Abstract

The embodiment of the invention provides a medical knowledge graph construction method and device based on electronic medical records. The method comprises the steps of extracting symptom entities from the electronic medical records with body parts as anchor points; constructing a binary entity pair of symptoms and symptom details for the symptom entity; determining a corresponding relationship type for the binary entity pair; and constructing a medical knowledge graph by taking two entities in the binary entity pair as nodes and taking the relationship type of the binary entity pair as an edge. According to the embodiment of the invention, the symptom entity is extracted by taking the body part as the anchor point in the electronic medical record, so that a relatively comprehensive symptom entity extraction result can be obtained, the completeness of the symptom entity in the medical knowledge graph is improved, and the reference value of the medical knowledge graph is further improved. In addition, a binary entity pair of symptoms and symptom details and a corresponding relationship type are constructed, so that the medical corresponding relationship between the symptoms and thesymptom details can be analyzed according to the medical knowledge graph.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, in particular to a method and device for constructing a medical knowledge map based on electronic medical records. Background technique [0002] Compared with the traditional knowledge representation, the knowledge map has the characteristics of rich semantics, friendly structure, massive scale, and excellent quality. When medical knowledge is represented in the knowledge map, the advantages of the knowledge map and related technologies can be used for disease reasoning applications. [0003] At present, in the process of constructing the medical knowledge map based on electronic medical records, there are problems of inaccurate, missing or wrong mention of symptom entities, which will affect the data integrity of the subsequent medical knowledge map and reduce the reference value of the medical knowledge map. . Contents of the invention [0004] In view of the prob...
