The last decade has witnessed the prevalence of sensor and GPS technologies that produce a high volume of trajectory data representing the motion history of moving objects. However some characteristics of trajectories such as variable lengths and asynchronous sampling rates make it difficult to fit into traditional database systems that are disk-based and(More)
Route recommendation is one of the most widely used location-based services nowadays, as it is vital for nice-driving experience and smooth public traffic. Given a pair of user-specified origin and destination, a route recommendation service aims to provide users with the routes of the best travelling experience according to given criteria. However, even(More)
In this paper, we study a route summarization framework for Personalized Navigation dubbed PerNav - with which the goal is to generate more intuitive and customized turn-by-turn directions based on user generated content. The turn-by-turn directions provided in the existing navigation applications are exclusively derived from underlying road network(More)
The proliferation of GPS-enabled smart mobile devices enables us to collect a large-scale trajectories of moving objects with GPS tags. While the raw trajectories that only consists of positional information have been studied extensively, many recent works have been focusing on enriching the raw trajectories with semantic knowledge. The resulting data,(More)
