Traditional Chinese medicine intelligent syndrome differentiation auxiliary decision-making method based on topic model technology

Abstract

The invention discloses a traditional Chinese medicine intelligent syndrome differentiation auxiliary decision-making method based on the topic model technology. The method comprises the following steps: normalizing symptom names in a medical record set; preprocessing a medical case data set: performing word segmentation processing on each medical case by using a language technology platform tool;generating a medical case topic model to obtain all topics implied in the medical case set; constructing a standard syndrome database based on the Internal Science of the Traditional Chinese Medicine, and obtaining the labels of the topics by calculating the similarity between symptom groups under the themes and standard syndromes, namely syndrome names; and performing syndrome prediction based on the mined syndrome groups. The symptom names in the medical record set are normalized, and the automatic standardization function of traditional Chinese medicine books is achieved. According to thesyndrome prediction method, the standardized medical record data is analyzed and processed, the syndrome differentiation function of the traditional Chinese medicine diagnosis and treatment system isachieved, and the syndrome differentiation result is more accurate.

Description

technical field [0001] The invention relates to an auxiliary decision-making method of traditional Chinese medicine, in particular to an auxiliary decision-making method of intelligent syndrome differentiation of traditional Chinese medicine based on topic model technology. Background technique [0002] "Syndrome differentiation and treatment" is the main feature of traditional Chinese medicine, which is to analyze and summarize the symptoms collected by looking, smelling, asking, and feeling (four diagnoses) according to the principle of combining the four diagnoses to determine the pathology, nature, location and pathogenic factors of the disease. Positive relationship, so as to determine the syndrome type of the disease, and choose the corresponding treatment. Syndrome differentiation in TCM is the theoretical core of TCM diagnosis of diseases, and it is also a difficult problem in TCM diagnostics. [0003] The syndrome differentiation mode of traditional Chinese medicin...
