Clinical pathway mining method based on body and topic model

The invention provides a clinical pathway mining method based on a body and a topic model. A clinical pathway conforming to the reality of a hospital is finally obtained according to given real charging data of the hospital and through five-stage processing containing data preprocessing, semantic approximate processing, topic clustering, topic sequence processing and clinical pathway mining. By using the clinical pathway mining method based on the body and the topic model, the clinical pathway of disease diagnosis and treatment, which conforms to the real situation of the hospital, can be obtained by starting from the real charging data of the hospital and through a series of data processing, so as to assist in making the clinical pathway conforming to the reality of the hospital; compared with manual making, the method is higher in efficiency and is moreover more objective and comprehensive.
