Overview

Randomized trial integrates knowledge graphs with AI to improve clinical question answering, indicating better data management.

Key Points

The study aims to construct a medical knowledge graph and enhance clinical practice through efficient knowledge services.
Integrated 44,157 entities and 291,170 relationships from an open-source database into a local medical KG using Neo4j.
Applied graph algorithms including degree centrality, Louvain community detection, K-nearest neighbor, and Dijkstra’s algorithm.
Developed a dual-channel question-and-answer system combining KG retrieval results with the Spark Lite model.
Identified highly related entities like acute urethritis and blood routine tests.
Detected 35 disease communities and 17 department communities.
Uncovered potential therapeutic pathways linking diseases and treatments.
