Beyond Verdicts: A Graph-Based Analysis of Human and LLM Reasoning in Scientific Fact-Checking

The paper introduces a typed reasoning graph framework to compare human and large language model (LLM) reasoning paths in scientific fact‑checking. By modeling explanations as graphs linking false claims to study context, findings, premises, and fallacy labels, the authors enable one‑to‑one alignment of human and LLM reasoning at the sub‑graph level. Using 84 false claims from MISSCIPLUS, they evaluate GPT‑5, Claude Opus 4.7, and Qwen3‑32B, finding distinct performance patterns: Qwen3‑32B has the lowest verdict failure rate, GPT‑5 shows the highest human alignment, and Claude Opus 4.7, while weak at verdict prediction, often produces valid reasoning in successful cases.

VeriGraph: Towards Verifiable Data-Analytic Agents

arXiv:2606. 16603v1 Announce Type: cross Abstract: LLM-based agents have demonstrated strong capabilities in data-intensive analytical tasks, yet their outputs are rarely verifiable: a reliance on linear text trajectories makes their reasoning difficult to audit.

Provenance-Enhanced Statements in Knowledge Graphs

arXiv:2606. 15246v1 Announce Type: cross Abstract: Provenance-enhanced statements of the form "according to $X$, $\varphi$" are pervasive in contemporary knowledge graphs, especially in domains where graph content primarily represents claims, interpretations, and hypotheses (\emph{capta}) rather than observer-independent facts (\emph{data}).

Generating Biomedical Fact-Checking Reports with RL-Enhanced Agentic Search

The paper introduces BioCheck Agent, an LLM-based system that generates structured biomedical fact‑checking reports using agentic search and a reinforcement‑learning framework called EG‑GRPO. Unlike prior methods that output only supported or refuted labels, BioCheck Agent synthesizes conclusions with retrieved evidence from PubMed, employing advanced Boolean search operators. Experiments show that, compared to the base Qwen3.5‑4B model, BioCheck Agent improves label prediction accuracy on SciFact by 9.95 %, raises evidence quality by 3.7 %, and reduces hallucinations by 19.63 %.
