Abstract
本说明书提供了一种异常业务识别的方法、装置、存储介质及电子设备。在本说明书提供的异常业务识别方法中,将各业务分别作为各节点,根据业务信息判断各业务之间的关联关系,并根据关联关系确定各节点之间的边;根据确定出的各节点和边,构建业务图;针对每个节点,确定参与该节点对应的业务的用户,将预先获得的用户的用户特征添加到该节点的节点信息中,其中,用户特征是预先根据用户执行该业务的业务信息,确定出的用户对应于每个预设的可疑用户识别规则集的特征;当接收到针对目标业务的识别请求时,在业务图中提取目标业务对应的节点的子图;将子图输入预先训练的识别模型中,根据识别模型的输出结果识别所述目标业务是否为异常业务。
