Abstract

This presentation highlights recent research relating to modeling moving objects where the focus is on spatiotemporal paths of objects and the semantics of these paths. Some of this work approaches moving objects research from an event-based perspective where the dynamic happenings or occurrents experienced by entities during movement are abstracted and modeled as events. This research gives insight into semantics including those of expected and unexpected events and movements, and provides a foundation for developing an ontology of movement types. This is useful, for example, for knowledge discovery tasks where different types of paths of movement may be revealed. Future research topics relating to moving objects and spatiotemporal paths are presented.
