Collaborative filtering meets next check-in location prediction

Defu Lian, Vincent W. Zheng, Xing Xie
2013 Proceedings of the 22nd International Conference on World Wide Web - WWW '13 Companion  
To this end, in this paper, we leveraged collaborative filtering techniques for check-in location prediction and proposed a short-and long-term preference model.  ...  Though location prediction in terms of check-ins has been recently studied, the phenomena that users often check in novel locations has not been addressed.  ...  (a)A typical scenario for next check-in location prediction. Given three successive checkins(tree icons) of a user(head icon), we predict her next location.  ...
