Abstract

The invention relates to a method for constructing a health knowledge graph. The method comprises the following steps of directly extracting entities of users, symptoms, diseases, experts, treatment schemes and commodities belonging to generalized representations in structured and semi-structured data from a network data source by utilizing an html label and a regular expression; extracting entities belonging to the six summarized representations from the unstructured data by using a conditional random field algorithm; using Bi-pairs of entities extracted in the same context The LSTM algorithmcarries out relation classification and determines a relation between entities; calculating the correlation between the entity names and the entity descriptions and achieving the disambiguation of the entity information; and complementing the knowledge graph relation by using an owl reasoning function of a jena tool, capturing ambiguous triplet by using a criterion, and feeding back the triplet which is judged to be possibly wrong to a domain expert for verification. The method has the beneficial effects that the health knowledge graph of the traditional Chinese medicine theory is constructed, the incomplete relation is automatically complemented by applying the knowledge reasoning technology, and the more perfect health graph is constructed.

Description

technical field [0001] The invention belongs to the technical field of health care, in particular to a method and system for constructing a health knowledge map Background technique [0002] At present, most of the knowledge maps in the field of health management are based on the theory of Western medicine. These maps pay more attention to disease prediction and rehabilitation treatment, and are lacking in regulating the body to prevent and treat diseases. Because Chinese medicine has a richer theoretical basis in the field of health management , so the knowledge graph based on TCM theory can make up for the deficiency of the existing health knowledge graph. There are too many, and it is impossible to recommend prescriptions for multiple symptoms, resulting in an incomplete map construction. Contents of the invention [0003] In order to solve the problem of incomplete map construction in the prior art, the present invention provides a method for constructing a health map...
