Overview

OpenFactCheck is an open-source repository designed to facilitate the evaluation and enhancement of factuality in responses generated by large language models (LLMs). This project aims to integrate various fact-checking tools into a unified framework and provide comprehensive evaluation pipelines.

Installation

You can install the package from PyPI using pip:

pip install openfactcheck

Usage

First, you need to initialize the OpenFactCheckConfig object and then the OpenFactCheck object.

from openfactcheck import OpenFactCheck, OpenFactCheckConfig

# Initialize the OpenFactCheck object
config = OpenFactCheckConfig()
ofc = OpenFactCheck(config)

Response Evaluation

You can evaluate a response using the ResponseEvaluator class.

# Evaluate a response
result = ofc.ResponseEvaluator.evaluate(response: str)

LLM Evaluation

We provide FactQA, a dataset of 6480 questions for evaluating LLMs. Onc you have the responses from the LLM, you can evaluate them using the LLMEvaluator class.

# Evaluate an LLM
result = ofc.LLMEvaluator.evaluate(model_name: str,
                                   input_path: str)

Checker Evaluation

We provide FactBench, a dataset of 4507 claims for evaluating fact-checkers. Once you have the responses from the fact-checker, you can evaluate them using the CheckerEvaluator class.

# Evaluate a fact-checker
result = ofc.CheckerEvaluator.evaluate(checker_name: str,
                                       input_path: str)
