Target object portrait construction method and system and storage medium

The invention discloses a target object portrait construction method and system and a storage medium, which are applied to the technical field of information and can dynamically update a target object portrait in real time and effectively improve the accuracy of the target object portrait. The method comprises the following steps: analyzing a use behavior event of a target object, and constructing behavior event data; wherein the behavior event data comprises a plurality of target object behavior events; creating a first behavior tree according to the behavior event data; wherein the first behavior tree comprises a plurality of behavior nodes, and the behavior nodes correspond to the target object behavior event; target object behavior data are obtained through a preset event-driven model, the first behavior tree is updated according to the target object behavior data, and a second behavior tree is generated; and analyzing the second behavior tree to construct and obtain the target object portrait. 本发明公开了一种目标
