Fact-checking benchmarks still contaminated despite dynamic evaluation

By PulseAugur Editorial · [1 sources] ·

A new study examines contamination risks in dynamic evaluation benchmarks for multimodal automated fact-checking (MAFC). The research found that even benchmarks designed with post-knowledge cut-off claims still suffer from contamination, with 17-29% of claims being potentially verifiable using pre-cut-off knowledge. This contamination can inflate MAFC performance estimates by up to 11.34 Macro-F1 points and alter system rankings. The study proposes guidelines for more trustworthy MAFC evaluation by strictly controlling for contamination. AI

IMPACT Highlights the need for more robust evaluation methods to accurately assess AI fact-checking capabilities.

    Novel Claim or Déjà Vu? Rethinking "Contamination-Free'' Dynamic Evaluation for Multimodal Automated Fact-Checking

    Multimodal automated fact-checking (MAFC) verifies claims by retrieving and reasoning over external evidence. However, most existing static benchmarks risk contamination: they primarily consist of outdated claims verifiable using an LLM's internal knowledge without external evide…
