Evaluation

The evaluation of the generated answers should follow the criteria below.

Evaluation Standards

We employ a combination of "Strict" and "Flex" approaches for a fair evaluation of answer correctness. Questions are labeled as either "Strict" or "Flex" to indicate which evaluation method should be used.

• Strict: For questions with a definite answer, such as a numerical or textual value explicitly labeled on the chart. This approach uses exact string matching for evaluation.
• Flex: For questions that require estimation of values, such as for unlabeled numerical data. This approach allows for a 5% tolerance when evaluating the correctness of the answer.
