Abstract:
The present invention discloses a method and a device for constructing a medical knowledge graph and an assistant diagnosis method. The assistant diagnosis method based on a medical knowledge graph comprises the steps of: acquiring complaint data and examination data of a patient and processing the data to obtain symptom entities and sign entities of the patient; searching, from the medical knowledge graph, disease entities associated with the symptom entities and the sign entities, calculating a posterior probability of each disease entity separately under a set of its corresponding symptom entities and sign entities; and outputting a disease entity with a maximum posterior probability as well as data corresponding to its associated nodes. The present invention provides an intelligent assistant diagnosis for clinical medicine to reduce the work burden of medical staff, relieve the medical pressure and reduce medical accidents.

Claim (Index 5):
An auxiliary query method for a medical knowledge graph based on the method according to  claim 2 , comprising the steps of:\n acquiring complaint data and examination data of a patient; preprocessing the complaint data and the examination data to obtain a set of symptom entities and sign entities of the patient; searching, from the medical knowledge graph, a set of disease entities associated with the symptom entities and the sign entities; calculating, based on the set of the disease entities and the set of the symptom entities and the sign entities corresponding to each disease entity, a posterior probability of each disease entity separately under a set of its corresponding symptom entities and sign entities; and outputting a disease entity with a maximum posterior probability as well as data corresponding to its associated nodes.
