Claim2Source system improves multilingual scientific claim-source retrieval · arXiv cs.IR

Researchers have developed a novel multi-stage retrieval framework to improve multilingual scientific claim-source identification. This system combines structured representations of claims and sources with a progressive refinement process. It addresses multilingual challenges by using bilingual claim representations, enhancing source representations with metadata, and adapting dense retrieval models for specific languages. The framework first generates a pool of candidate sources, then refines the ranking using similarity and verification signals to pinpoint the best supporting source, achieving a top ranking on the CheckThat! 2026 leaderboard with an MRR@5 score of 0.7628 across English, German, and French claims.

    Claim2Source at CheckThat! 2026: Improving Multilingual Scientific Claim-Source Retrieval with Verification-based Re-Ranking

    Multilingual scientific claim-source retrieval aims to identify the scientific publication supporting a claim shared on social media. This task is challenging because claims often differ from source publications in terms of language, wording, and level of detail, which weakens th…
