DATA PUSHING METHOD AND SYSTEM BASED ON BEHAVIOR TRAJECTORY, AND COMPUTER DEVICE

摘要

A data pushing method based on a behavior trajectory. The method comprises: receiving a data pushing instruction triggered by a target user by means of a target user terminal (S100); according to the data pushing instruction, acquiring target historical behavior data of the target user from a behavior log system (S102); constructing a target trajectory graph of the target user according to the target historical behavior data (S104); extracting a target trajectory feature vector of the target user according to the target trajectory graph (S106); inputting the target trajectory feature vector into a recall model so as to obtain a plurality of pieces of initial pushing data (S108); inputting the plurality of pieces of initial pushing data into a classification model so as to obtain a plurality of pieces of target pushing data (S110, S112); and pushing the plurality of pieces of target pushing data to a front end for presentation (S114). In the method, a trajectory graph is constructed for a user according to behavior trajectories of the user, and similarity matching is performed on the trajectories of the user by means of a classification model and a regression model, thereby improving the accuracy and efficiency of data recommendation.
