Embodiment 1

[0116] refer to image 3 , which shows a flow chart of the steps of Embodiment 1 of a method for constructing a knowledge graph in the present invention. This embodiment is used to construct a knowledge graph, and may specifically include the following steps:

[0117] Step 301. Determine the problem entity according to the disease characteristic entity; the above problem entity is used to represent the problems related to the above disease characteristic entity;

[0118] Step 302, in the knowledge map, establish the association between the above-mentioned disease feature entity and the above-mentioned question entity.

[0119] In step 301, the disease feature entity may represent features related to the disease, which may include: disease features that appear in the disease, or include: disease features that cannot appear in the disease.

[0120] In an optional embodiment of the present invention, the process of determining the disease characteristic entity may include: deter...

Embodiment 2

[0166] refer to Figure 4 , shows a flow chart of the steps of Embodiment 2 of a method for constructing a knowledge map of the present invention, and this embodiment may specifically include the following steps:

[0167] Step 401, determine the main complaint list;

[0168] In practical applications, chief complaints can be obtained from medical inquiry data and / or medical record data, chief complaints can be screened according to preset criteria, and a chief complaint list can be established based on the screened chief complaints.

[0169] Step 402, determining the list of diseases;

[0170] The doctor constructs a list of diseases according to the diseases corresponding to each chief complaint. These diseases are the collection of diseases in the knowledge graph.

[0171] Step 403, feature expansion;

[0172] In practical applications, the disease characteristics in the disease list can be expanded based on medical resources such as medical books and network resources, ...

Embodiment 3

[0180] refer to Figure 5 , which shows a flow chart of the steps of an embodiment of a method for using a knowledge map in the present invention. This embodiment is used for medical inquiry. The method may specifically include the following steps:

[0181] Step 501, according to the disease characteristic entity corresponding to the target disease characteristic, obtain the corresponding question entity from the knowledge map; the above question entity is used to represent the problems related to the above disease characteristic entity;

[0182] Step 502: Determine the target question according to the above question entity, and the above target question is used to inquire the user.

[0183] The embodiment of the present invention can be applied to the scenario of consultation. Inquiry is a method of diagnosing diseases by purposely inquiring patients or agents to understand the occurrence, development, diagnosis and treatment process, current symptoms and other conditions re...

Abstract

The embodiment of the invention provides a knowledge graph construction and use method and device and a medium. The method specifically comprises the following steps: determining a problem entity according to a disease feature entity, wherein the question entity is used for representing a question related to the disease feature entity; and in the knowledge graph, establishing association between the disease feature entity and the question entity. According to the embodiment of the invention, the effect of the knowledge graph on inquiry can be improved, and the processing accuracy of the medical information can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of medical technology, and in particular to a method for constructing and using a knowledge map, a device and a medium. Background technique [0002] With the popularity of the Internet and the increase of medical resources, more and more users will search for medical information on the Internet to determine possible diseases. [0003] The current medical information processing methods usually use the knowledge graph to connect the trivial and scattered medical information knowledge to each other. The knowledge graph usually includes the edge relationship between the disease entity and the symptom entity; and based on the above edge relationship, the user's symptom prediction is obtained the corresponding disease. [0004] In the process of implementing the embodiment of the present invention, the inventor found that an important factor in medical information processing is to obtain enough s...
