A Study of EMR-based Medical Knowledge Network and Its Applications

Highlights • We construct an EMR-based medical knowledge network (EMKN) to represent medical knowledge. • The network shows some complex properties, including small-world property, scale-free property and community structure. • Based on the network, we propose a simple but universal diagnosis model. This model takes symptom entities as inputs, and returns the disease entities as outputs. • This model only needs simple features as inputs, and is not restricted to a specific disease. • Our study results experimentally demonstrate the effectiveness of EMKN.
