A method and device for measuring the similarity of traditional Chinese medicinal materials

Abstract

The invention provides a method and an apparatus for measuring similarity between traditional Chinese medicinal materials. The method comprises the following steps of S1: giving two traditional Chinese medicinal materials, querying compatible medicinal materials compatible with the given traditional Chinese medicinal materials, and establishing compatibility sets corresponding to the given medicinal materials based on compatibility frequencies of the compatible medicinal materials; S2: obtaining a union set of the two compatibility sets; S3: establishing compatibility eigenvectors about the two given medicinal materials; and S4: measuring the similarity between the two traditional Chinese medicinal materials through a cosine value of an included angle between the two compatibility eigenvectors in an inner product space. According to the method provided by the invention, the similarity between the two traditional Chinese medicinal materials can be objectively reflected based on medicine compatibility laws in a large amount of Chinese medicinal formulae, thereby facilitating assessment of medicinal material similarity during search of substitutive medicinal materials for scarce traditional Chinese medicinal materials.

Description

technical field [0001] The invention relates to the field of medical data processing, in particular to a method and device for measuring the similarity of 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 t...
