Ev2R: Evaluating Evidence Retrieval in Automated Fact-Checking

no code implementations8 Nov 2024 Mubashara Akhtar, Michael Schlichtkrull, Andreas Vlachos

Current automated fact-checking (AFC) approaches commonly evaluate evidence either implicitly via the predicted verdicts or by comparing retrieved evidence with a predefined closed knowledge source, such as Wikipedia.

AVeriTeC: A Dataset for Real-world Claim Verification with Evidence from the Web

3 code implementations NeurIPS 2023 Michael Schlichtkrull, Zhijiang Guo, Andreas Vlachos

Existing datasets for automated fact-checking have substantial limitations, such as relying on artificial claims, lacking annotations for evidence and intermediate reasoning, or including evidence published after the claim.
