Abstract

This paper presents an approach for modeling semantics associated with occurrents in geospatial domains. Occurrents correspond to what is commonly thought of as a happening or activity in the real world. We describe a modeling approach where representations of occurrents are modeled as classes of events. Additional semantics are gained by modeling specialized subclasses of event classes as derived events. Significant occurrents are modeled as noteworthy events, i.e., happenings or activities in a domain that require intervention, for example, an automated notification that a noteworthy event has been detected. The representation is extended to treat event sequences that capture a variety of occurrent-based semantics, modeling both routine and unexpected occurrents as experienced, for example, by moving entities, such as vessels in a harbor.
