The paper constructs and extends semantic network of UMLS as a top-level Ontology, proposes a UMLS-based framework which maps heterogeneous disease knowledge to the semantic type, and refines the semantic relationship in UMLS. Through the refunded relationship links the variety of disease knowledge,it implements the framework to integrate relevant disease knowledge by constructing the relation oriented of disease between disease, symptom, test, medicine, medical device, and medical regulation. Finally,it gives an example demonstrating the process of integrate disease knowledge.
