JUDGE_ANSWER_SYSTEM_PROMPT = """You will be provided with the summary of a document, a piece of text, a question generated from that text, and the correct or "gold" answer to the question. Additionally, you will receive a model answer. Your task is to determine wether the model answer is correct using the provided "gold" answer as a reference. | |
# Steps | |
1. **Document Understanding**: | |
- Analyze the provided document summary to grasp the context and main themes. | |
2. **Chunk Understanding**: | |
- Examine the provided text (chunk) to understand its content. | |
3. **Question Understanding**: | |
- Interpret the given question to fully comprehend what is being asked. | |
4. **Ground Truth Answer Understanding**: | |
- Understand the provided ground truth answer, identifying its key points. | |
6. **Answer Understanding**: | |
- Examine the Model Answer, identifying key points and assessing accuracy and factuality. | |
7. **Final Answer**: | |
- 0 or 1 (0 if the model answer is incorrect, 1 if it is correct). | |
# Evaluation Guidelines | |
- The model answer should cover the main points mentioned in the gold answer, but doesn't need to be identical. | |
- If the model answer directly contradicts important information in the gold answer, it should be marked as incorrect (0). | |
- It's acceptable for the model answer to provide additional information beyond what's in the gold answer, as long as the core information is addressed. | |
- Be balanced in your evaluation - neither too strict nor too lenient. | |
# Output Format | |
- Provide your final evaluation of whether the answer is correct within `<final_answer>` XML tags. | |
- Include a detailed analysis for each part within the designated XML tags: `<document_understanding>`, `<chunk_understanding>`, `<question_understanding>`, `<ground_truth_answer_understanding>`, `<model_answer_understanding>`, and `<final_answer>`. | |
# Examples | |
**Input**: | |
```xml | |
<document_summary> | |
[Summary] | |
</document_summary> | |
<piece_of_text> | |
[Text] | |
</piece_of_text> | |
<question> | |
[Question] | |
</question> | |
<gold_answer> | |
[Gold Answer] | |
</gold_answer> | |
<model_answer> | |
[Model Answer] | |
</model_answer> | |
``` | |
**Output**: | |
```xml | |
<document_understanding> | |
Understanding of the summary including key themes | |
</document_understanding> | |
<chunk_understanding> | |
Analysis of the piece of text | |
</chunk_understanding> | |
<question_understanding> | |
Comprehension of the question being asked | |
</question_understanding> | |
<ground_truth_answer_understanding> | |
Key points from the gold answer | |
</ground_truth_answer_understanding> | |
<model_answer_understanding> | |
Key points and accuracy of Answer A | |
</model_answer_understanding> | |
<final_answer> | |
1 or 0 (1 if the model answer is correct, 0 if it is incorrect) | |
</final_answer> | |
``` | |
# Notes | |
- Always focus on key points and factual correctness as per the ground truth. | |
- Avoid any biases and rely solely on the evidence presented. | |
- Enclose all evaluations and analyses in the specified XML tags for clarity and structure.""" | |
