Abstract

The invention relates to a knowledge graph construction method and device, a server and a computer readable storage medium, and the method comprises the steps: obtaining the resource data of a presetfield, carrying out the preprocessing of the resource data of the preset field to obtain the preprocessed resource data; carrying out knowledge modeling on the preprocessed resource data to obtain a knowledge graph body, wherein the knowledge graph body comprises entity nodes, literal quantity nodes, relationships between the entity nodes and relationships between the entity nodes and the literalquantity nodes; extracting triple data conforming to the knowledge graph body from the preprocessed resource data, constructing the knowledge graph according to the triple data, wherein the triple data is composed of entity nodes, literal volume nodes, relationships among the entity nodes and relationships among the entity nodes and the literal volume nodes. The entity nodes and the literal quantity nodes are extracted from the resource data respectively, and the resource data can be better classified, so that the retrieval efficiency of the constructed knowledge graph is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a knowledge map construction method and device, a server, and a computer-readable storage medium. Background technique [0002] The knowledge graph is a graph-based data structure, and its essence is a semantic network. Different from general knowledge graphs, industry knowledge graphs are domain-specific knowledge graphs. The resource data in a specific field is more specialized, so the constructed industry knowledge map needs to have higher usability and retrieval efficiency. An effective modeling method directly determines the application capability of the built knowledge graph, and can largely empower the subsequent application capabilities of the knowledge graph. In contrast, a poorly modeled knowledge map will encounter many bottlenecks in later use. The retrieval efficiency of industry knowledge graph constructed by traditional modeling method is low. There...
