Based on the analysis of the concept and characteristics of social perception,this paper analyzes the connotation and extension of user spatio-temporal behavioral profile and proposes a user spatio-temporal behavioral profile based on social sensing data,which includes three major modules:social sensing data collection and processing,profile implementation and profile application layer.The semantic association model is further proposed,and its implementation path in various scenarios is summarized.The effective integration of social sensing data,user profile technology and profile services can realize the innovation of user behavior research level and the application of cross-research,and provide theoretical support and decision-making basis for the information reconstruction of user spatio-temporal behavior and the implementation of user spatio-temporal behavioral profile in social sensing environment.
