Location and Time Aware Social Collaborative Retrieval for New Successive Point-of-Interest Recommendation

A new model called location and time aware social collaborative retrieval model (LTSCR) is proposed, which has two distinct advantages: (1) it models the location, time, and social information simultaneously for the successive POI recommendation task; and (2) it efficiently utilizes the merits of the collaborative retrieved model which leverages weighted approximately ranked pairwise (WARP) loss for achieving better top-n ranking results.
