Medical knowledge graph construction method and device, medium and electronic equipment

Abstract

The invention provides a medical knowledge graph construction method and device, a medium and electronic equipment. The method comprises: acquiring a clinical data set, wherein the clinical data set comprises a plurality of doctor seeing records; calculating main diagnosis information in the treatment record, and performing data cleaning based on the main diagnosis information; extracting entitiesfrom the cleaned data, and determining entity relationship pairs and relationship weights among the entities in the entity relationship pairs according to at least two types of entities; and constructing a medical knowledge graph according to the entity relationship pair and the relationship weight between the entities in the entity relationship pair. According to the technical scheme, the flexibility of obtaining different entities is facilitated by setting the plurality of data sources, the entity information is further accurately obtained, and the accuracy of constructing the medical knowledge graph is further improved. Moreover, the process of constructing the medical knowledge graph supports cold start, and does not need to depend on the existing medical knowledge graph.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular, relates to a method for constructing a medical knowledge graph, a device for constructing a medical knowledge graph, a computer-readable medium, and an electronic device. Background technique [0002] Medical knowledge graph technology is a key technology that enables computer algorithm systems to understand medical knowledge. Exemplarily, the computer algorithm system can realize various medical tasks such as auxiliary diagnosis and treatment, medical record quality control, intelligent diagnosis guidance, and automatic underwriting based on medical knowledge map technology. How to establish a medical knowledge map is a concern of relevant staff. [0003] Medical knowledge generally comes from the following two aspects: on the one hand, literature knowledge, which is obtained through studying textbooks, clinical guidelines, monographs and papers, etc.; on the...

Problems solved by technology

Exemplary, related existing technologies can only be used if there is an "existing medical knowledge graph", which leads to limited use scenarios and cannot be applied to cold start conditions

However, it is generally difficult to obtain a perfect existing medical knowledge map. If there is an error in the medical knowledge map knowledge at the start of the project, the accuracy of the entity alignment algorithm will be greatly affected, and the error of the generated knowledge map will be greater.

[0006] It can be seen that the accuracy of the medical knowledge map determined by the method provided by the existing technology needs to be improved
