AI system uses knowledge graphs for improved conversational medical diagnosis

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a conversational diagnosis system that leverages diagnostic knowledge graphs to improve accuracy and efficiency. The system first generates diagnostic hypotheses based on dialogue context and then verifies these hypotheses through clarifying questions. To evaluate the system, they utilized PatientSim, a persona-driven patient simulator, along with patient data from MIMIC-IV, and adapted it to reflect vague symptom reporting from real-world patients. Experiments demonstrated superior diagnostic accuracy and efficiency compared to existing methods, with physician evaluations confirming the simulator's realism and the clinical utility of the generated questions. AI

IMPACT This research could lead to more accurate and efficient AI-powered diagnostic tools, improving patient care and medical training.

    Think Like a Doctor: Conversational Diagnosis through the Exploration of Diagnostic Knowledge Graphs

    arXiv:2602.01995v2 Announce Type: replace Abstract: Conversational diagnosis requires multi-turn history-taking, where an agent asks clarifying questions to refine differential diagnoses under incomplete information. Existing approaches often rely on the parametric knowledge of a…
