A new study published on arXiv explores the potential of large language models (LLMs) to annotate bioassay metadata, aiming to improve data readiness for molecular property prediction. Researchers quantified significant gaps in metadata coverage within the PubChem database, with over 36% of assays lacking an assay format and nearly 90% missing a BioAssay type. The study found that both open-source and proprietary LLMs demonstrated high recall in predicting assay formats and detection methods, often agreeing with existing labels and even prompting expert curators to revise their own annotations. While LLMs show promise for large-scale metadata curation and auditing, the research indicates that per-class reliability estimates and human review are still essential before these labels can be integrated into downstream machine learning pipelines.

IMPACT LLMs can potentially automate and improve the quality of bioassay metadata, accelerating downstream ML pipelines in drug discovery and chemical research.
