Abstract

The invention relates to a knowledge graph construction method and device based on knowledge node affiliation degree, computer equipment and a storage medium. The method comprises the steps of obtaining a target knowledge node and a subordinate knowledge node of the target knowledge node, wherein the target knowledge node and the subordinate knowledge node are knowledge nodes in a preset domain; calculating the affiliation degree from the subordinate knowledge node to the target knowledge node according to the path length from the target knowledge node to the subordinate knowledge node, wherein the path length is determined by the number of intermediate knowledge nodes connected from the target knowledge node to the subordinate knowledge node; when the affiliation degree from the subordinate knowledge node to the target knowledge node is lower than a threshold value, deleting the subordinate knowledge node, and obtaining residual knowledge nodes in the preset domain; and constructing aknowledge graph according to the remaining knowledge nodes in the preset domain. By adopting the method, the construction efficiency of the knowledge graph can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a method and device for constructing a knowledge graph based on the degree to which a knowledge node belongs. Background technique [0002] A knowledge graph is a large-scale semantic network that uses entities or concepts as knowledge nodes and is connected by semantic relationships. By exploring the associations between entities and integrating semi-structured and unstructured data, knowledge graphs can help machines understand data, explain phenomena, and reason about knowledge, so as to discover deep relationships, realize intelligent search and intelligent interaction. At present, it is widely used in banking, insurance, securities, court, logistics, finance and taxation and other fields. The knowledge graph is composed of multiple knowledge nodes, and the multiple knowledge nodes are related to each other, and their interrelated relationships are represent...
