Traditional Chinese medicine meridian prescription ancient book knowledge graph construction and syndrome mining system

Abstract

The invention discloses a traditional Chinese medicine meridian prescription ancient book knowledge graph construction and syndrome mining system. The system comprises a knowledge graph construction module which is used for obtaining concept terms, carrying out entity classification, obtaining the relation between corresponding entities, constructing a knowledge graph, and importing the knowledge graph into a graph database to form an entity graph; and a knowledge mining module which further comprises a graph mapping unit which is used for extracting all symptom nodes in the entity graph as sub-graph nodes, and counting the number of times of symptom co-occurrence as a weight of edges in a sub-graph, wherein the co-occurrence is that two symptom nodes are connected through the same intermediate node in the entity graph, and the category of the intermediate node is not limited; and a community discovery calculation unit which is used for acquiring symptom sub-graph data after graph mapping, calculating a community distribution rule of symptoms, and obtaining the number of communities, modularity, the number of nodes and specific nodes, namely specific symptoms, included in each community, wherein each community represents one syndrome, and the number of the nodes represents symptoms possibly appearing under the syndromes.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a knowledge map construction and syndrome mining system of ancient books of classic prescriptions of traditional Chinese medicine. Background technique [0002] The main clinical manifestations of diabetes are polydipsia, polyphagia, polyuria, thirst, fatigue, weight loss, or sweet-smelling urine, which can be seen in modern medicine such as diabetes. Traditional Chinese medicine has clear advantages in improving low insulin resistance and protecting islet function. However, physicians in the past dynasties have different understandings of diabetes, resulting in a lack of standardization of its syndrome. Jingfang is a theoretical system of Han and Tang Dynasty prescription medicine based on Zhang Zhongjing's six meridian syndrome differentiation as the theoretical core. Syndrome differentiation of the six meridians reclassifies deficiency, excess, cold and heat on the exteri...

Problems solved by technology

Although factor analysis and other methods can find the co-occurrence of symptoms, the premise assumes that the symptoms of different syndromes are relatively independent, which is inconsistent with the clinical reality; the dimensionality reduction of the data in the calculation also leads to information loss
