<i>MetaHarmonizer</i> : robust biomedical metadata harmonization and a contamination control for inflated LLM performance on public benchmarks

2026-06-17

Abstract excerpt

Public biomedical repositories hold substantial reuse potential, but inconsistent metadata routinely blocks integration across studies. Recent LLM-based harmonization approaches address scale but suffer from non-determinism, hallucinated ontology terms, and, in their highest-accuracy configurations, dependence on proprietary APIs or labeled fine-tuning data. A more fundamental concern is that LLM accuracies on wid...
