FactCheck Editor is an innovative text editor designed to address the widespread issue of misinformation by automating the fact-checking process. It supports over 90 languages and utilizes transformer models to assist human writers in the labor-intensive task of verifying the accuracy of their content.
The system consists of three key components:
Claim Detection: FactCheck Editor first identifies check-worthy claims in the written text using sentence segmentation, co-reference resolution, and a multilingual claim classification model. This model, fine-tuned on datasets in multiple languages, outperforms large language models (LLMs) in detecting claims that warrant verification.
Evidence Retrieval: The system then generates effective search queries to retrieve relevant documents from the web, including scholarly articles and previous fact-checks, to gather evidence for verifying the identified claims. It employs techniques like query generation, search engine retrieval, and deduplication to ensure comprehensive and credible sources.
Veracity Prediction: Finally, FactCheck Editor utilizes a Natural Language Inference (NLI) model, fine-tuned on multilingual datasets, to predict the veracity of each claim based on the retrieved evidence. It also generates summaries of the evidence and suggests textual revisions to correct any factual errors in the content.
The effectiveness of the models used for claim detection and veracity prediction is evaluated across multiple languages, demonstrating the system's ability to provide end-to-end fact-checking capabilities in a multilingual setting. This tool has the potential to assist human writers, particularly in sectors like news and media, by helping them detect and correct factual errors early in the content creation process.
