Embodiment 1

[0057] figure 1 It is a flow chart of the knowledge graph construction method provided by the embodiment of the present invention.

[0058] refer to figure 1 , the knowledge map construction methods include:

[0059] Step S101, establishing the infrastructure of the knowledge graph according to common data standards;

[0060] Step S102, unify and standardize the relationship between entities in the infrastructure to obtain a standard dictionary table with standard specifications;

[0061] Further, step S102 can be implemented by taking the following steps:

[0062] Convert entity attributes of entities into triple data RDF (Resource Description Framework, triple data);

[0063] According to RDF, entity attributes and entity relationship types and naming rules are standardized.

[0064] Here, medicine is taken as an example for explanation. Medical textbooks and medical literature are the main basis and basis for establishing traditional medical knowledge maps. It has ma...

Abstract

The invention provides a knowledge graph establishment method and system. The knowledge graph establishment method comprises the steps that a basic architecture of a knowledge graph is established according to general data standards; the relations of entities in the basic architecture are normalized in a unified mode to obtain a standard dictionary table having standard specifications; semi-structural data associated with contents in the knowledge graph is obtained; entity information of key entities is extracted from the semi-structural data; data fusion is conducted on the entity information according to the standard dictionary table to form structural data; the structural data form corresponding data structure pairs, and the data structure pairs are stored as the knowledge graph. The data is obtained and data fusion is completed by establishing the basic architecture of the knowledge graph and utilizing multiple network channels, the function converting the semi-structural data into the structural data is achieved, and a foundation is laid for further development of artificial intelligence technologies on the basis.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a method and system for constructing a knowledge graph. Background technique [0002] The construction of knowledge graph is the core of realizing the application of artificial intelligence technology in specific industries. Previous knowledge graphs were mainly based on existing subject textbooks and literature knowledge, and were obtained through secondary processing and editing. These knowledge graphs have shortcomings such as huge manual workload, limited coverage of knowledge fields, and few entities and related relationships, making it difficult to meet the current application requirements for processing massive data scenarios. [0003] In addition, a large amount of structured data is the basis for specific applications and services of artificial intelligence technology. At the same time, for highly specialized disciplines, the research progresses...
