Embodiment Construction

[0023] The invention provides a method for recommending traditional Chinese medicinal materials based on an LDA topic model, which includes the following contents:

[0024] 1. Medical case preprocessing

[0025] Firstly, the medical record information of multiple cases of a certain disease is collected, and the medical record data are preprocessed. After processing, each medical record information contains a set of syndrome words s and medicinal material words h.

[0026] 2. Mining hidden pathogenesis to build a model

[0027] Based on the syndrome word s and drug word h in the processed medical records, a topic model based on syndrome-treatment-drug is constructed, and parameter learning and training are carried out.

[0028] Assuming that each medical case is regarded as a document, and a pathogenic mechanism is regarded as a subject, let |C| be the number of clinical medical records, each medical case c contains a set of syndromes and n kinds of drugs, h cn is the nth dru...

Abstract

The invention discloses a traditional Chinese medicine recommendation method based on an LDA topic model, relates to the technical field of traditional Chinese medicine recommendation, and aims to apply a hidden Dirichlet model in machine learning to traditional Chinese medicine recommendation and establish a corresponding topic model so as to observe the accuracy of recommended medicines and provide preliminary screening and decision support for traditional Chinese medicine recommendation. The invention has the advantages that the problem that in the prior art, traditional Chinese medicine formula rule mining lacks consideration on implicit treatment methods is solved, traditional Chinese medicine formula recommendation precision and efficiency are improved, and preliminary screening and auxiliary decision support are provided for formulas in the diagnosis and treatment process of traditional Chinese medicine doctors.

Description

technical field [0001] The invention belongs to the technical field of recommending traditional Chinese medicinal materials, and in particular relates to a method for recommending traditional Chinese medicinal materials based on an LDA topic model. Background technique [0002] Traditional Chinese medicine culture is a medical culture formed in the long-term practice and clinical treatment of famous Chinese medicine practitioners in the past dynasties. It carries the valuable experience and theoretical knowledge of the Chinese nation for thousands of years. Syndrome is a general term for a series of interrelated symptoms, that is, the state of body reaction and its movement and changes at the overall level in the disease process learned through the four clinics of looking, smelling, asking, and cutting, referred to as syndrome or syndrome, syndrome It is also the basic basis for Chinese medicine to establish treatment principles and adopt the most appropriate technical metho...
