Abstract

The invention provides a disease diagnosis method based on path reasoning of a medical knowledge graph, and relates to the field of the medical knowledge graph. The method comprises the steps that: a user inputs first symptom information, queries in the medical knowledge graph, queries in a synonym table, and searches for diseases associated with similar symptoms by adopting an entity alignment method, symptoms associated with the diseases are summarized and returned to the user, score ranking in a first candidate disease list is updated through real-time interaction with the user, and finally the diseases in the first candidate disease list serve as diagnosis results and are returned to the user.

Description

technical field

[0001] The present invention relates to the field of medical knowledge graphs, in particular to a disease diagnosis method based on path reasoning of medical knowledge graphs. Background technique

[0002] The biggest problem facing the current medical care is still the problem of insufficient medical resources. As one of the research hotspots of smart medical care, intelligent disease diagnosis can not only reduce the pressure on medical staff, but also improve the accuracy of disease diagnosis. Traditional rule-based knowledge reasoning methods mainly use simple rules or statistical features on the knowledge graph for reasoning, and use the relationship between triples on the knowledge graph for disease diagnosis.

[0003] At present, for common diseases, in the absence of inspection and inspection indicators, according to the age, gender, pregnancy and related symptoms provided by the user, the path reasoning technology based on the medical knowledge map i...

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] This application relates to a disease diagnosis method based on path reasoning of medical knowledge graph, including the following steps:

[0039] S1: According to the first input symptom input by the user, select initial symptoms and candidate diseases, and generate a first symptom list and a first candidate disease list;

[0040] Further, the selection of the initial symptoms inclu...
