Point of Interest Recommendation

Abstract

With the rapid development of wireless communication technologies, location-based social networks, such as Foursquare and Gowalla, have become very popular. This makes it possible to mine user’s preference on locations and provided favourite recommendations. However, check-in data is sparse, long-tail, temporal and sociability. In this talk, we consider recommendation system using tensor method for handling such types of data with various techniques. Experiments on a real check-in database show that the proposed method can offer better location recommendation. The work is done jointly with Yiyuan LIU, and Ya WANG.
