Abstract

One or more embodiments of the invention disclose an information prediction method and device based on label propagation, which are used for realizing high efficiency and high accuracy of informationprediction based on a label propagation mode. The method comprises the following steps: acquiring first tags of specified types of a plurality of sample users; acquiring behavior information of each sample user and a to-be-predicted user; determining an initial label of the to-be-predicted user according to the first label and the behavior information; determining a dynamic label propagation algorithm corresponding to each iteration; and, according to the first label, iterating the initial label by using the dynamic label propagation algorithm, and when the iteration meets a preset convergencecondition, determining that the label obtained by the last iteration is the second label of the specified type of the user to be predicted.

Description

technical field [0001] This specification relates to the technical field of information prediction, and in particular to an information prediction method and device based on tag propagation. Background technique [0002] With the rapid development of mobile Internet and financial technology, code scanning payment has gradually become a mainstream payment method due to its fast and safe features, bringing great convenience to people's lives. In the entire payment link of scan code payment, the payee (B-end merchant, hereinafter referred to as the merchant) is one of the very important participants. However, due to information asymmetry and other reasons, some unscrupulous merchants engage in some abnormal commercial activities (such as fraud, gambling, etc.) by means of scanning code payment, which poses a serious threat to the property safety of customers and seriously affects the normal business environment and business. order. [0003] In order to deal with merchant risk...
