Ontology-guided multi-agent framework for explainable differential diagnosis
A new arXiv paper (arXiv:2610.36325v1) proposes an ontology-guided, multi-agent framework that grounds differential diagnosis in an expert-curated medical knowledge base, decomposes inference into auditable reasoning steps, and generates targeted follow-up questions to reduce uncertainty; the authors report improvements in transparency and reduced hallucination and have made the source code public. The approach is designed to constrain model output to evidence-backed associations while mirroring iterative clinical inquiry.
KEY POINTS
- A new arXiv paper (arXiv:2610.36325v1) proposes an ontology-guided, multi-agent framework that grounds differential diagnosis in an expert-curated medical knowledge base, decomposes inference into auditable reasoning steps, and generates targeted follow-up questions to reduce uncertainty; the authors report improvements in transparency and reduced hallucination and have made the source code public.
- The approach is designed to constrain model output to evidence-backed associations while mirroring iterative clinical inquiry.
- Grounding diagnostic reasoning in an expert ontology and explicit multi-step agents can reduce hallucination and make AI-assisted differential diagnosis more transparent and auditable, with code available for replication.
