A method and device for mining similar Chinese medicinal materials

Abstract

The present invention provides a method and device for mining similar Chinese herbal medicines. The method includes: S1: For a given set of medicines, construct a set of commonly used compatible medicines and a word frequency set of compatible medicines for each of the medicines; S2: Based on step S1 Calculate the similarity between any two medicinal materials in the drug collection, and form a drug similarity matrix; S3: take each medicinal material in the drug collection as a cluster, according to the step The drug similarity matrix obtained in S2 is used to establish a cluster set of clusters whose similarity is greater than the reference threshold by means of hierarchical clustering, and the medicinal materials in each cluster are similar medicinal materials. The present invention uses a big data mining method instead of mining the similarity relationship of traditional Chinese medicines, which can deal with the analysis of massive data of traditional Chinese medicines, and has high mining precision.

Description

technical field [0001] The invention relates to the field of medical data mining, in particular to a method and device for mining similar Chinese medicinal materials. Background technique [0002] Chinese medicinal materials are the constituent units of traditional Chinese medicine prescriptions and Chinese patent medicines, and are indispensable raw materials for major Chinese medicine clinics, pharmacies and Chinese medicine pharmaceutical factories. In actual situations, it often happens that a certain medicinal material, such as tiger bone and rhino horn, has been listed as an endangered species of traditional Chinese medicine or is protected from being mined by the state, or a certain medicinal material cannot be available in time due to market shortages. At the same time, According to the patient's financial ability, some precious Chinese medicinal materials are also excluded from the scope of medication consideration. Above all situations, all make the compatible dru...

Problems solved by technology

All of the above situations lead to the lack of compatible drugs in the original prescription and make the patient unable to take the medicine according to the prescription.

At present, most of the search for substitutes for scarce Chinese medicinal materials relies on the knowledge and experience of Chinese medical practitioners to search manually. Facing the massive data of Chinese medicinal materials and the huge demand for substitutes for scarce medicinal materials, it seems powerless
