摘要：Recently, GPS and mobile devices allowed collecting a huge amount of mobility data. Researchers fromdifferent communities have developed models and techniques for mobility analysis. But they mainly focusedon the geometric properties of trajectories and do not consider the semantic facet of moving objects. Thetechniques are good at extracting patterns, but they are hard to interpret in a specific application domain.This paper proposes a methodology to understand mobility data and semantically interpret trajectorypatterns. The process considers four different behavior types such as semantic, semantic and space,semantic and time, and semantic and space-time. Finally, a system prototype was developed to evaluate thebehavior models in different aspects using one of the location based services. The results showed thatapplying the semantic association rules could significantly reduce the number of available services andcustomize the services based on the rules.
