Abstract

The invention provides a fraudulent group mining method, device and electronic equipment. In the method, the original data is preprocessed to obtain the processed data. The preprocessing process can delete the noise data before the map is constructed. , reducing the influence of noise data on map building. At the same time, the process of iterative preprocessing and division processing is carried out until the number of nodes in each group of community data in the finally obtained multiple groups of community data is not greater than the preset threshold, or , until the number of nodes in each group of community data in multiple groups of community data no longer changes, and then visualize each group of divided community data to obtain a community network graph. In this way, each community network graph obtained does not have a large number of The node conforms to the characteristics of fraudulent gangs, and is convenient for visualization and subsequent evaluation of fraudulent gangs. The finally determined fraudulent gangs have good accuracy, which alleviates the technical problem of poor accuracy of existing fraudulent gang mining methods.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a fraud group mining method, device and electronic equipment. Background technique [0002] With the popularity of various loans or loan-like businesses in the financial field, gang fraud cases have gradually increased, causing varying degrees of losses to investors, companies and the country. Various companies and institutions are eager to seek a technical solution to discover gang fraud cases, so as to take precautions, prevent and recover losses in time. [0003] The existing method of mining fraudulent gangs is to first segment the data through the community discovery algorithm, obtain multiple communities after segmentation, and then evaluate the fraudulent gangs in each community to determine the fraudulent gangs. However, the existing community discovery algorithms are all based on the technical segmentation of data based on the characteristics of the network topology, ...
