BeLink: Generative Re-Ranking for Biomedical Entity Linking

ai-technology · 2026-05-23

BeLink is a modular end-to-end system for Biomedical Entity Linking (BEL) that integrates a generative re-ranker. The system uses instruction-tuned open-source large language models at the re-ranking stage to improve efficiency and accuracy. A set-wise instruction-tuning formulation enables fast candidate selection. On multiple BEL benchmarks, BeLink achieves 3% to 24% improvement in linking accuracy while reducing inference time compared to state-of-the-art methods. The work addresses the computational inefficiency of LLM-based BEL in practical settings.
