OntoCodex: a multi-agent biomedical ontology enrichment framework [PDF]
npj Health SystemsOntology enrichment is a critical but labor-intensive step in semantic knowledge representation. To address this challenge, we propose OntoCodex, a multi-agent framework that integrates large language models (LLMs), ontologies, curated knowledge sources,
