The invention relates to a malicious community discovery method and device, computer equipment and a readable storage medium, and the method comprises the steps: obtaining the ordering behavior data of a target user, and the ordering behavior data comprises a plurality of ordering behavior features; according to the ordering behavior data, classifying the target users to obtain a user classification result; obtaining a user system relationship, and constructing a first network topological graph according to the user classification result, the user system relationship and the ordering behaviordata; classifying the target users according to the first network topological graph and a preset label propagation rule to obtain a target community set; wherein the target community set comprises a plurality of target communities; and performing malicious group detection on the target community set according to a preset malicious detection rule to obtain malicious communities in the target community set. Through application of the method and the device, the problem that malicious groups in a community cannot be effectively detected in related technologies is solved.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a malicious community discovery method, device, computer equipment and readable storage medium. Background technique [0002] In the e-commerce scenario, there may be gangs of brushing orders or scalpers in some communities. If these communities are not detected by malicious groups, the risk control ability of the platform will be too low and the operating cost will be too high. , It will also lead to the problem of poor user experience. [0003] In related technologies, a community discovery algorithm is used to detect malicious groups in the community, so as to improve the risk control capability of the platform. However, this method can only realize the community discovery of a single attribute node, and it is impossible to accurately locate the malicious group in the community only by the community discovery result of a single attribute node, so that it is imposs...
