摘      要：With the development of network services and location-based systems,many mobile applications begin to use users’geographical location to provide better *** terms of social networks,geographical location is actively shared by *** some applications with recommendation services,before the geographical location recommendation is provided,the authors have to obtain user’s *** kind of social network integrated with geographical location information is called location-based social networks(abbreviate for LBSNs).In the LBSN,each user has location information when he or she checked in hotels or feature *** on this information,they can identify user’s trajectory of movement behaviour and activity *** general,if there is friendship between two users,their trajectories in reality are likely to be *** this study,according to user’s geographical location information over a period of time,they explore whether there exists friendly relationship between two users based on trajectory similarity and the structure theory of *** particular,they propose a new factor function and a factor graph model based on user’s geographical location to predict the friendship between two users in the real LBSN.
