Abstract

Events are at least as important as objects in modeling the dynamic universe. Modeling the real world and weaving the web of events require Composite Events that are valid constitution of atomic and composite sub-events. The progress in event composition has been limited to construction of some entities and relationships in upper ontologies such as Event-Model-F, and DSO ontology that are extensions of BFO,DOLCE, and E-Model. For building a composite event from atomic events, different operators must be used to provide right attributes for this event. Event Composition Operators on all attributes of events should be defined. The knowledge of context semantics of sub-event facets should be used for valid population of the resulting composite event attributes. Our contribution and focus in this paper is to define and implement such event composition operators on spatial and temporal aspect of events.
