Embodiment Construction

[0050] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0051] figure 1 A flowchart showing the method for constructing the medical knowledge map of the present invention.

[0052] refer to figure 1 , the method for constructing the medical knowledge map of the present invention specifically includes the following steps:

[0053] S11. Collect data in the medical database and build a user dictionary.

[0054] In this embodiment, in the existing medical database, relevant data are collected according to ICD-10 and ICD-9-CM, and a user dictionary is constructed.

[0055] S12. Process the electronic medical record data according to the user dictionary and the stop word thesaurus.

[0056] In this embodiment, the data used to c...

Abstract

The invention discloses a method and device for establishing a medical knowledge graph, and an auxiliary diagnosis method. The method for establishing the medical knowledge graph comprises the steps that a user dictionary is established according to a medical database; electronic medical record data is processed, and named entity recognition is conducted; correlation relations are established for each recognized entity; and the medical knowledge graph is established according to the correlation relations. The auxiliary diagnosis method based on the medical knowledge graph comprises the steps that a patient's chief complaint data and inspection data are acquired and processed, so that a symptom entity and a sign entity of the patient can be obtained; a disease entity correlated with the symptom entity and the sign entity is searched in the medical knowledge graph, and a posterior probability of each disease entity in a set composed of the corresponding symptom entity and the sign entity is computed respectively; and the disease entity with the maximum posterior probability and data corresponding to correlated nodes of the disease entity are output. According to the invention, intelligent auxiliary diagnosis is provided for clinical medical science, so that working burdens of medical workers are relieved; medical stress is relieved; and occurrence rate of medical accidents is reduced.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a construction method, device and auxiliary diagnosis method of a medical knowledge map. Background technique [0002] As a structured information network, the knowledge map breaks the limitations of the original relational database and has a very powerful expressive ability. It plays an increasingly important role in the fields of information retrieval and information integration, and can provide users with A wider and deeper knowledge system is constantly expanding. [0003] At present, the knowledge map is widely used. In the medical field, the construction of a medical knowledge map can build a database through the intricate relationship between diseases, diseases and diagnosis and treatment methods, so as to provide medical staff with good information. Auxiliary diagnostic tools. However, the structure of the existing medical knowledge map is relatively sim...
