BioELX: Cross-lingual Biomedical Entity Linking via Alias-based Retrieval and LLM Ranking

Researchers introduce BioELX, a two-stage cross-lingual biomedical entity linking system that maps medical mentions across languages to knowledge base identifiers without requiring task-specific training data. The framework combines multilingual alias-enriched retrieval with LLM-based ranking, achieving state-of-the-art results across five benchmarks with substantial improvements for low-resource languages.

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.

Generalistic or Specific Embeddings, Which is Better? An Empirical Study on Search for Clinical Coding in Non-English Languages

Researchers demonstrate that fine-tuning Spanish biomedical embeddings with synthetic data generated by large language models significantly improves clinical code retrieval across multiple European languages. The two-stage retrieval system outperforms existing benchmarks like BioBERT-ST, particularly for non-English languages, addressing a critical gap in multilingual medical AI applications.

Beyond Agreement: Scoring Panel-Surfaced Biomedical Entity Candidates for Curator Triage

Researchers introduce BioConCal, a supervised scoring system that evaluates biomedical entity candidates surfaced by multiple LLMs across five public datasets. The tool improves candidate verification from 75.3% to 91% AUROC by leveraging agreement patterns and document features, enabling more efficient curator review workflows rather than recovering missed entities.
