Abstract

The embodiment of the invention provides an abnormal group identification method and device. The method comprises the steps of obtaining a feature value of each user to be analyzed in a plurality of users to be analyzed; Determining a high-frequency characteristic value and a low-frequency characteristic value in the characteristic values of the users to be analyzed; Mining a maximum frequent itemset according to the high-frequency characteristic value of each to-be-analyzed user and a preset frequent item set mining strategy, and obtaining a low-frequency maximum frequent characteristic value in the maximum frequent item set; Constructing a target bipartite graph according to the low-frequency maximum frequent characteristic value and the low-frequency characteristic value in the characteristic values of the users to be analyzed, and defining the weight of an edge in the target bipartite graph; And determining an abnormal group in the to-be-analyzed user according to the weight of the edge in the target bipartite graph and a clustering result of a plurality of to-be-analyzed users obtained by performing graph clustering on the target bipartite graph. According to the embodiment of the invention, the accuracy of abnormal group recognition is improved, and the steps are simple and easy to execute.

Description

technical field [0001] This specification relates to the field of computer technology, in particular to a method and device for identifying abnormal groups. Background technique [0002] At present, in various scenarios in the field of risk control (such as spam registration, marketing cheating, stealing cards and stealing accounts, fraudulent insurance, etc.), the tendency of gangs to commit crimes is becoming more and more obvious, which seriously affects the normal business order and brings great harm to merchants. caused huge losses. Therefore, how to identify gangs (that is, abnormal groups) has become one of the important issues in the operation process of merchants. [0003] In the commonly used identification methods of abnormal groups, the accuracy of identifying abnormal groups is low due to the lack of labeled samples and the variability of abnormal groups' crime methods. Contents of the invention [0004] The purpose of one or more embodiments of this specifi...
