Abstract

The invention discloses a risk gang identification method and device. The method comprises the steps that a risk knowledge graph is constructed based on user historical behaviors and a lost user list,the risk knowledge graph comprises non-user nodes, lost user nodes hitting the lost user list and common user nodes not hitting the lost user list, and the non-user nodes represent attribute characteristics of a user; the risk template is acquired, Wherein the risk template comprises a plurality of template nodes and connecting edges between the template nodes, the template nodes comprise one ormore of a non-user node, a lost credit user node and a common user node, and the connecting edges are used for representing that the connected template nodes have an association relationship; nodes matched with the risk template and connecting edges between the nodes are extracted from the risk knowledge map to form a risk map; And the nodes in the risk map are divided into a plurality of groups by adopting a community division algorithm, and the nodes in each group are identified as the same risk gang.

Description

technical field [0001] This specification relates to the field of artificial intelligence technology, and in particular to a method and device for identifying risk groups. Background technique [0002] With the rapid development of Internet finance, Internet fraud is gradually on the rise. Gangs with security risks such as black industry and black intermediaries control a large number of user accounts through illegal means, and use these user accounts for arbitrage, disrupting Internet financial security. Contents of the invention [0003] In view of this, this specification provides a method and device for identifying risk groups. [0004] Specifically, this specification is realized through the following technical solutions: [0005] A method for identifying a risk group, comprising: [0006] Construct a risk knowledge map based on user history behavior and a list of dishonest users, the risk knowledge map includes: non-user nodes, dishonest user nodes that hit the lis...
