DecomposeRL: Learning to Ask Useful, Informative, and Diverse Questions for Semi-Supervised, Traceable Claim Verification

DecomposeRL presents a novel reinforcement learning approach to claim verification that achieves high accuracy while maintaining interpretability through decomposition-based reasoning. A 7B parameter model trained on just 5K curated claims matches 32B baselines and GPT-4.1-mini across 11 benchmarks while enabling semi-supervised learning, demonstrating efficient scaling through intelligent data curation.

Fine-Grained Uncertainty Quantification for Long-Form Language Model Outputs: A Comparative Study

Researchers introduce a comprehensive framework for detecting hallucinations in long-form language model outputs through fine-grained uncertainty quantification, finding that simpler claim-level consistency methods outperform complex alternatives. The study provides practical guidance for improving factuality in extended LLM generations across STEM and geography domains.

BioDivergence: A Benchmark and Evaluation Framework for Hidden Contextual Contradictions in Biomedical Abstracts

Researchers introduce BioDivergence, a new evaluation framework that distinguishes between genuine contradictions and context-dependent divergences in biomedical research claims. The framework includes a six-class taxonomy and 13-axis ontology to capture why studies produce seemingly conflicting results, with a released benchmark of 11,865 claim pairs showing that current NLI models struggle with contextual understanding.

Neurosymbolic Learning for Inference-Time Argumentation

Researchers introduce Inference-Time Argumentation (ITA), a neurosymbolic framework that combines large language models with formal argumentation semantics for claim verification. The system generates arguments, scores them, and produces ternary (true/false/uncertain) predictions with faithful, inspectable reasoning structures rather than post-hoc justifications.

DeepSciVerify: Verifying Scientific Claim--Citation Alignment via LLM-Driven Evidence Escalation

Researchers present DeepSciVerify, an LLM-based system that verifies scientific claims against cited evidence by combining abstract-level analysis with selective full-text passage retrieval. The two-stage pipeline achieves 86.7% accuracy on benchmarks while reducing computational overhead by avoiding unnecessary full-text analysis in 67% of cases, addressing a critical reliability issue in AI-generated scientific content.

Checking Fact with Better Retrieval: Dynamic Contrastive Learning for Evidence Retrieval

Researchers propose DACLR, a dynamic contrastive learning method that improves evidence retrieval for multimodal fact-checking by converting diverse media types to text and extracting event-level features. The approach uses a two-stage recall-rerank system with adaptive loss functions to better match claims with relevant evidence rather than merely semantically similar content.
