Abstract

The invention relates to a behavior recognition method and device, an electronic device and a storage medium, and relates to the technical field of the Internet. The method comprises the following steps of constructing a graph model based on order data corresponding to historical behaviors of a user, and determining the initial confidence coefficient of each node contained in the graph model; obtaining community features and comprehensive features for the user through the order data; determining a message value of the graph model according to the community features, the comprehensive features,the initial confidence coefficient and a message updating rule, determining the graph model according to the message value, and calculating the confidence coefficient of the order data correspondingto a current behavior through the graph model so as to determine a recognition result of the current behavior according to the confidence coefficient. According to the method, the graph model for theuser can be established from multiple dimensions, so that the graph model is more accurate, the user behavior is accurately recognized, and the accuracy is improved.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and in particular, to a behavior recognition method, a behavior recognition device, electronic equipment, and a computer-readable storage medium. Background technique [0002] Due to the large transaction volume and imperfect monitoring methods of Internet finance, it is easy to become the first choice for fraudsters to swipe orders and cash out. However, the single amount of mobile phone recharge payment is small and the daily transaction volume is large, and the fraudulent behavior that occurs in it is more likely to be missed by the monitoring system. [0003] In the common mobile phone recharge anti-fraud scheme, it is generally judged whether the user's current recharge request is a fraudulent act based on real-time information such as the user's account information and behavior characteristics. The input data are all single feature data, and the graph model constructed from s...
