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...
