QA-Evaluation-Metrics
QA-Evaluation-Metrics is a fast and lightweight Python package for evaluating question-answering models. It provides various basic metrics to assess the performance of QA models. Check out our paper CFMatcher, a matching method going beyond token-level matching and is more efficient than LLM matchings but still retains competitive evaluation performance of transformer LLM models.
Installation
To install the package, run the following command:
pip install qa-metrics
Usage
The python package currently provides four QA evaluation metrics.
Exact Match
from qa_metrics.em import em_match
reference_answer = ["Charles , Prince of Wales"]
candidate_answer = "Prince Charles"
match_result = em_match(reference_answer, candidate_answer)
print("Exact Match: ", match_result)
Transformer Match
Our fine-tuned BERT model is this repository. Our Package also supports downloading and matching directly. More Matching transformer models will be available 🔥🔥🔥
from qa_metrics.transformerMatcher import TransformerMatcher
question = "who will take the throne after the queen dies"
tm = TransformerMatcher("distilroberta")
scores = tm.get_scores(reference_answer, candidate_answer, question)
match_result = tm.transformer_match(reference_answer, candidate_answer, question)
print("Score: %s; distilroberta Match: %s" % (scores, match_result))
F1 Score
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)
match_result = f1_match(reference_answer, candidate_answer, threshold=0.5)
print("F1 Match: ", match_result)
CFMatch
from qa_metrics.cfm import CFMatcher
question = "who will take the throne after the queen dies"
cfm = CFMatcher()
scores = cfm.get_scores(reference_answer, candidate_answer, question)
match_result = cfm.cf_match(reference_answer, candidate_answer, question)
print("Score: %s; CF Match: %s" % (scores, match_result))

Updates
- [01/24/24] 🔥 The full paper is uploaded and can be accessed here. The dataset is expanded and leaderboard is updated.
- Our Training Dataset is adapted and augmented from Bulian et al. Our dataset repo includes the augmented training set and QA evaluation testing sets discussed in our paper.
- Now our model supports Distilroberta, a smaller and more robust matching model than Bert!
