Moving Objects beyond Raw and Semantic Trajectories

Mobile applications, for example for road traffic monitoring, mobile health and animal data ecology, call for methods enabling rich and expressive representation of moving objects. This demand motivates the increasing concern for the paradigm of semantic trajectories. In this paper, I overview related research, focusing in particular on the novel data model of symbolic trajectories proposed for the efficient and flexible handling of semantics-aware trajectories through a Moving Object DBMS.
