Abstract

One or more embodiments of the invention provide a risk group identification method and device, and the method comprises the steps: obtaining the business behavior data of a to-be-risk-controlled target business; based on the service behavior data and the at least one target medium type, constructing a first relationship network graph, wherein the first relational network graph comprises a user node and a medium node corresponding to a target medium type, and the target medium type is determined based on edge weight data obtained by using a trained graph deep learning model. And performing group division on the plurality of user nodes in the first relationship network graph by using a preset group division mode to obtain a plurality of target groups. And in the plurality of target groups,determining a risk group according to the business behavior data of each target group.

Description

technical field [0001] This document relates to the computer field, in particular to a risk group identification method and device. Background technique [0002] At present, with the advent of the Internet age, the Internet has been widely used in people's daily study, work and life. People's daily affairs can be processed and presented through the Internet. However, there are more and more Internet fraud incidents, especially gang fraud will bring a lot of financial losses. Therefore, it is particularly important to accurately identify and quickly prevent and control gang fraud incidents. [0003] At present, since group attacks are a group of users using similar methods to commit crimes, the users used to commit crimes will have close aggregation in some dimensions. Therefore, community discovery methods are usually used to detect such a group of users with close relationships. to identify. Among them, when applying the community discovery method, both users and media (...
