User behavior analysis method and device and computer readable storage medium

The invention provides a user behavior analysis method and device, and a computer readable storage medium. The method comprises the steps of determining behavior characteristics of each user node in atime window; processing the behavior characteristics of each user node by using a machine learning model to obtain a first evaluation value of each user node, the user node of which the first evaluation value is greater than a first threshold being a first user node; determining a second evaluation value of the first user node according to a knowledge graph, the second evaluation value representing an association degree between the first user nodes; determining a third evaluation value of the first user node according to the first evaluation value and the second evaluation value of the firstuser node; and judging the first user node of which the third evaluation value is greater than a second threshold value as a target user node. By means of the method, group behavior characteristics such as real person gang che
