Tutorial: Model-Driven Software Development with Semantic Web Technologies
Event-Model-F
Abstract
The lack of a formal model of events hinders interoperability in distributed event-based systems. In this paper, we present a formal model of events, called Event-Model-F. The model is based on the foundational ontology DOLCE+DnS Ultralight (DUL) and provides comprehensive support to represent time and space, objects and persons, as well as mereological, causal, and correlative relationships between events. In addition, the Event-Model-F provides a flexible means for event composition, modeling event causality and event correlation, and representing different interpretations of the same event. The Event-Model-F is developed following the pattern-oriented approach of DUL, is modularized in different ontologies, and can be easily extended by domain specific ontologies.
Ontology
The event ontology F is available here: model.owl
Example
emergency-example.zip - This file is an example of an event modeled in our F ontology. It demonstrates the application of the composition pattern and participation pattern in the domain of emergency response and is taken from the technical report.
flooding-example.zip - Another example in the emergency response domain. It models an excerpt from a flooding.
soccer-example.zip - This zip-archive contains a set of ontologies describing a soccer game event in our event model F. It demonstrates the full use of all patterns of F, namely participation, causality, correlation, composition, and interpretation. It further shows how a domain specific ontology can be embedded and used to describe the events happening during a soccer game.
weekend-example.zip - This ontology is an example of an event modeled in our F ontology from the domain of tourism. It defines a two-day weekend trip with three people participating in it. On the first day, there is a sub-event dinner. On the second day are two sub-events a visit to a museum and a sight.
