The invention discloses a mining and auxiliary decision intelligent system for traditional Chinese medicine text medical records and relates to the technical field of natural language processing and traditional Chinese medicine diagnosis auxiliary information. The system is based on unstructured text medical record of real standard clinic medical record; automatic traditional Chinese medicine principle-method-recipe-medicines, treatment according to syndrome differentiation and knowledge extraction and expression are realized; the system comprises a database which is in a rear end server and traditional Chinese medicine and pharmacy knowledge atlas on-line\off-line applications in a front end computer; major formulas, symptom pairs, syndromes, traditional Chinese medicine pathogenesis evolution rule and data links of mutual relation among the above knowledge elements are stored in the database according certain data storage structure. Through the map node retrieval, node set retrieval and area positioning of the traditional Chinese medicine and pharmacy knowledge atlas, the obtained analysis results are mixed with features such as directed network, semantic distance, coordinate setting and topology analysis based on hierarchical cluster, which greatly increases the discovery capability of major formulas, symptom pairs, syndromes, traditional Chinese medicine pathogenesis evolution rule and mutual relation among the above knowledge elements.
