FRAUD GANG IDENTIFICATION METHOD AND DEVICE

摘要

Implementations of the present specification provide a fraud gang identification method and device. The method includes: constructing a relational network that includes a plurality of nodes; performing cluster discovery based on the relational network to obtain at least one fraud gang included in the relational network, each fraud gang including the plurality of nodes; determining a weak node from the nodes included in the fraud gang, the weak node being a node whose association with the fraud gang meets a weak association criterion; and removing the weak node from the fraud gang to identify a final target fraud gang.
