+
+[![PyPI version qa-metrics](https://img.shields.io/pypi/v/qa-metrics.svg)](https://pypi.org/project/qa-metrics/) 
+[![Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/drive/17b7vrZqH0Yun2AJaOXydYZxr3cw20Ga6?usp=sharing)
+
+QA-Evaluation-Metrics is a fast and lightweight Python package for evaluating question-answering models and prompting of black-box and open-source large language models. It provides various basic and efficient metrics to assess the performance of QA models. 
+
+### Updates
+- Uopdated to version 0.2.8 
+  - Supports prompting OPENAI GPT-series models and Claude Series models now. (Assuimg OPENAI version > 1.0)
+  - Supports prompting various open source models such as LLaMA-2-70B-chat, LLaVA-1.5 etc by calling API from [deepinfra](https://deepinfra.com/models).
+
+
+## Installation
+* Python version >= 3.6
+* openai version >= 1.0
+
+
+To install the package, run the following command:
+
+```bash
+pip install qa-metrics
+```
+
+## Usage/Logistics
+
+The python package currently provides six QA evaluation methods. 
+- Given a set of gold answers, a candidate answer to be evaluated, and a question (if applicable), the evaluation returns True if the candidate answer matches any one of the gold answer, False otherwise.
+- Different evaluation methods have distinct strictness of evaluating the correctness of a candidate answer. Some have higher correlation with human judgments than others.
+- Normalized Exact Match and Question/Answer type Evaluation are the most efficient method. They are suitable for short-form QA datasets such as NQ-OPEN, Hotpot QA, TriviaQA, SQuAD, etc.
+- Question/Answer Type Evaluation and Transformer Neural evaluations are cost free and suitable for short-form and longer-form QA datasets. They have higher correlation with human judgments than exact match and F1 score when the length of the gold and candidate answers become long.
+- Black-box LLM evaluations are closest to human evaluations, and they are not cost-free.
+
+## Normalized Exact Match
+#### `em_match`
+
+Returns a boolean indicating whether there are any exact normalized matches between gold and candidate answers.
+
+**Parameters**
+
+- `reference_answer` (list of str): A list of gold (correct) answers to the question.
+- `candidate_answer` (str): The answer provided by a candidate that needs to be evaluated.
+
+**Returns**
+
+- `boolean`: A boolean True/False signifying matches between reference or candidate answers.
+
+```python
+from qa_metrics.em import em_match
+
+reference_answer = ["The Frog Prince", "The Princess and the Frog"]
+candidate_answer = "The movie \"The Princess and the Frog\" is loosely based off the Brother Grimm's \"Iron Henry\""
+match_result = em_match(reference_answer, candidate_answer)
+print("Exact Match: ", match_result)
+'''
+Exact Match:  False
+'''
+```
+
+## F1 Score
+#### `f1_score_with_precision_recall`
+
+Calculates F1 score, precision, and recall between a reference and a candidate answer.
+
+**Parameters**
+
+- `reference_answer` (str): A gold (correct) answers to the question.
+- `candidate_answer` (str): The answer provided by a candidate that needs to be evaluated.
+
+**Returns**
+
+- `dictionary`: A dictionary containing the F1 score, precision, and recall between a gold and candidate answer.
+
+```python
+from qa_metrics.f1 import f1_match,f1_score_with_precision_recall
+
+f1_stats = f1_score_with_precision_recall(reference_answer[0], candidate_answer)
+print("F1 stats: ", f1_stats)
+'''
+F1 stats:  {'f1': 0.25, 'precision': 0.6666666666666666, 'recall': 0.15384615384615385}
+'''
+
+match_result = f1_match(reference_answer, candidate_answer, threshold=0.5)
+print("F1 Match: ", match_result)
+'''
+F1 Match:  False
+'''
+```
+
+## Efficient and Robust Question/Answer Type Evaluation
+#### 1. `get_highest_score`
+
+Returns the gold answer and candidate answer pair that has the highest matching score. This function is useful for evaluating the closest match to a given candidate response based on a list of reference answers.
+
+**Parameters**
+
+- `reference_answer` (list of str): A list of gold (correct) answers to the question.
+- `candidate_answer` (str): The answer provided by a candidate that needs to be evaluated.
+- `question` (str): The question for which the answers are being evaluated.
+
+**Returns**
+
+- `dictionary`: A dictionary containing the gold answer and candidate answer that have the highest matching score.
+
+#### 2. `get_scores`
+
+Returns all the gold answer and candidate answer pairs' matching scores.
+
+**Parameters**
+
+- `reference_answer` (list of str): A list of gold (correct) answers to the question.
+- `candidate_answer` (str): The answer provided by a candidate that needs to be evaluated.
+- `question` (str): The question for which the answers are being evaluated.
+
+**Returns**
+
+- `dictionary`: A dictionary containing gold answers and the candidate answer's matching score.
+
+#### 3. `evaluate`
+
+Returns True if the candidate answer is a match of any of the gold answers.
+
+**Parameters**
+
+- `reference_answer` (list of str): A list of gold (correct) answers to the question.
+- `candidate_answer` (str): The answer provided by a candidate that needs to be evaluated.
+- `question` (str): The question for which the answers are being evaluated.
+
+**Returns**
+
+- `boolean`: A boolean True/False signifying matches between reference or candidate answers.
+
+
+```python
+from qa_metrics.pedant import PEDANT
+
+question = "Which movie is loosley based off the Brother Grimm's Iron Henry?"
+pedant = PEDANT()
+scores = pedant.get_scores(reference_answer, candidate_answer, question)
+max_pair, highest_scores = pedant.get_highest_score(reference_answer, candidate_answer, question)
+match_result = pedant.evaluate(reference_answer, candidate_answer, question)
+print("Max Pair: %s; Highest Score: %s" % (max_pair, highest_scores))
+print("Score: %s; PANDA Match: %s" % (scores, match_result))
+'''
+Max Pair: ('the princess and the frog', 'The movie "The Princess and the Frog" is loosely based off the Brother Grimm\'s "Iron Henry"'); Highest Score: 0.854451712151719
+Score: {'the frog prince': {'The movie "The Princess and the Frog" is loosely based off the Brother Grimm\'s "Iron Henry"': 0.7131625951317375}, 'the princess and the frog': {'The movie "The Princess and the Frog" is loosely based off the Brother Grimm\'s "Iron Henry"': 0.854451712151719}}; PANDA Match: True

+## Updates
+- [01/24/24] 🔥 The full paper is uploaded and can be accessed [here](https://arxiv.org/abs/2402.11161). The dataset is expanded and leaderboard is updated.
+- Our Training Dataset is adapted and augmented from [Bulian et al](https://github.com/google-research-datasets/answer-equivalence-dataset). Our [dataset repo](https://github.com/zli12321/Answer_Equivalence_Dataset.git) includes the augmented training set and QA evaluation testing sets discussed in our paper. 
+- Now our model supports [distilroberta](https://huggingface.co/Zongxia/answer_equivalence_distilroberta), [distilbert](https://huggingface.co/Zongxia/answer_equivalence_distilbert), a smaller and more robust matching model than Bert!
