Abstract

The invention discloses a risk gang identification method and device. The method comprises the following steps: constructing a risk knowledge graph based on historical behaviors of a trusted user, wherein the risk knowledge graph comprises a non-user node, a trusted user node and a common user node associated with the trusted user; Extracting nodes matched with a risk template and connection edgesbetween the nodes from the risk knowledge map to form a risk map; For each node in the risk map, according to the time parameter of the occurrence time of the incidence relation between the node anda neighbor node and the degree of the neighbor node, carrying out iteration on the label of the node, and after one round of iteration is completed, judging whether a modularity function with time aggregation is converged or not; And when the modularity functions with the time aggregation converge, identifying the nodes with the same tags as the same risk gangs.

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 graph based on the historical behavior of untrustworthy users. The risk knowledge graph includes: non-user nodes, untrustworthy user nodes, and common u...
