Abstract

The invention provides a Chinese electronic case text analysis method and system. The method includes following steps: obtaining a case data set by employing case texts; separating value variables andtext information through regularization processing, determining value information meaning according to context description, and searching and structurally saving time information of different categories by employing a regular expression; performing word segmentation and part-of-speech tagging on the texts by employing natural language processing, performing further screening with the combinationof medical entity identification, and determining positions and types of medical key vocabularies in the texts; analyzing and screening the medical key vocabularies and information; simulating cases by employing the above related results; converting content of the texts to value vectors; adding similarity tags to the case texts; learning marks of the case texts; and screening the cases with the similarity on new case samples from the case data set according to the marks and training results. According to the method and system, for different evaluation standards, different similar case text clusters can be found from existed case texts for each new case text.

Description

technical field [0001] The invention relates to the technical field of machine learning, in particular to a text analysis method and system for Chinese electronic medical records. Background technique [0002] Auxiliary diagnosis system based on electronic medical information analysis has been widely used with the improvement of hospital electronic and informationalization. In addition to gaining diagnosis and treatment experience for new patients from past medical records, doctors can also get inspiration from the treatment methods of other similar patients stored in the auxiliary diagnosis system. Analyzing and utilizing information stored in electronic medical records can help doctors make accurate diagnoses. The purpose of the present invention is to analyze the past medical records. If the experts have already made a judgment on the similarity of some of the medical records, the present invention will analyze the newly arrived medical records according to the similarit...
