Analysis
This paper addresses the limitations of Large Language Models (LLMs) in clinical diagnosis by proposing MedKGI. It tackles issues like hallucination, inefficient questioning, and lack of coherence in multi-turn dialogues. The integration of a medical knowledge graph, information-gain-based question selection, and a structured state for evidence tracking are key innovations. The paper's significance lies in its potential to improve the accuracy and efficiency of AI-driven diagnostic tools, making them more aligned with real-world clinical practices.
Key Takeaways
- •MedKGI integrates a medical knowledge graph to ground reasoning in validated medical ontologies.
- •The framework selects questions based on information gain to maximize diagnostic efficiency.
- •An OSCE-format structured state is used to maintain consistent evidence tracking across turns.
- •MedKGI outperforms strong LLM baselines in both diagnostic accuracy and inquiry efficiency.
