Loki: An Open-source Tool for Fact Verification
Overview
Loki is our open-source solution designed to automate the process of verifying factuality. It provides a comprehensive pipeline for dissecting long texts into individual claims, assessing their worthiness for verification, generating queries for evidence search, crawling for evidence, and ultimately verifying the claims. This tool is especially useful for journalists, researchers, and anyone interested in the factuality of information.

from factcheck import FactCheck

factcheck_instance = FactCheck()

# Example text
text = "Your text here"

# Run the fact-check pipeline
results = factcheck_instance.check_response(text)
print(results)

Used as a Web App
python webapp.py --api_config demo_data/api_config.yaml

Multimodal Usage
# String
python -m factcheck --modal string --input "MBZUAI is the first AI university in the world"
# Text
python -m factcheck --modal text --input demo_data/text.txt
# Speech
python -m factcheck --modal speech --input demo_data/speech.mp3
