BioELX framework achieves SOTA in cross-lingual biomedical entity linking

Researchers have developed BioELX, a novel two-stage framework for cross-lingual biomedical entity linking that does not require task-specific annotated training data. The first stage enhances a retriever with multilingual aliases from Wikidata to improve candidate retrieval across languages. The second stage employs a pre-trained LLM ranker for context-aware disambiguation, considering both mention context and candidate entities. Experiments demonstrate that BioELX achieves new state-of-the-art performance on several benchmarks, particularly for low-resource languages. AI

IMPACT This framework could significantly improve cross-lingual biomedical NLP applications, especially for low-resource languages, by reducing the need for extensive annotated data.
