Abstract

The invention discloses a knowledge graph generation method and device, a relation mining method and device, equipment and a medium, and relates to the field of knowledge graphs. According to the specific implementation scheme, the method comprises the steps of obtaining an initial knowledge graph, wherein the initial knowledge graph comprises a plurality of nodes with a connection relationship; determining a plurality of target map elements meeting set attribute information requirements from the initial knowledge graph, the map elements comprising at least one of a target node and a target edge; and combining the plurality of target map elements to generate a knowledge graph. According to the embodiment, the nodes and the edges can express more attribute information, and the expression capability of the knowledge graph is improved; moreover, the graph structure can be reduced, and when the knowledge graph is applied to business scenes such as dynamic relationship mining, the analysisprocess can be simplified, the calculation amount can be reduced, and the calculation efficiency can be improved.

Description

technical field [0001] This application relates to computer technology, especially to the field of knowledge map technology. Background technique [0002] Knowledge graph (Knowledge Graph) is called knowledge domain visualization or knowledge domain mapping map in the library and information industry. Analyze, construct, map and display knowledge and their interconnections. [0003] Taking the social relationship knowledge graph as an example, the nodes in the graph represent people, and the edges between nodes represent the relationship between people; taking the financial knowledge graph as an example, the nodes in the graph represent accounts, and the edges between nodes represent accounts The transfer relationship with the account. The lack of expressive ability of existing knowledge graphs makes it difficult for knowledge graphs to play an effective role when applied to business scenarios such as relationship mining.
