SciTrue: Evidence-Grounded Claim Verification in Science

AbstractLarge language models (LLMs) have expanded the potential for AI-assisted scientific claim verification, yet existing systems often exhibit unverifiable attributions, shallow evidence mapping, and hallucinated citations. We present SciTrue, a claim verification system providing source-level accountability and evidence traceability. SciTrue links each claim component to explicit, verifiable scientific sources, enabling users to inspect and challenge model inferences, addressing limitations of both general-purpose and search-augmented LLMs. In a human evaluation of 300 attributions, SciTrue achieves high fidelity in summary traceability, attribution accuracy, and context alignment, substantially outperforming RAG-based baselines such as GPT-4o-search-preview and Perplexity Sonar Pro. These results underscore the importance of principled attribution and context-aware reasoning in AI-assisted scientific verification. A system demo is available at .
