Re: [ontolog-forum] Event Ontology

Dear Azamat and all


It is very interesting that on this mailinglist a similar discussion 
started that happened some time ago on the Linked Open Data mailinglist. 
Thus, firstly I like to refer to the relevant thread on the LOD list:
http://lists.w3.org/Archives/Public/public-lod/2009Jul/

In fact, the concept of events is well studied in foundational sciences 
such as philosophy. This work was the input for the development of the 
Event-Model-F. There is some brief description about that model in the 
LOD mailinglist archive as well:
http://lists.w3.org/Archives/Public/public-lod/2009Jul/0383.html

The Event-Model-F provides comprehensive support to represent time and 
space, objects and persons participating in events, and 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.
It will be presented this Friday at the Knowledge Capturing conference 
(K-CAP) in Redondo Beach, CA.

Further information on the ontology can be found on its web page, 
including the ontology itself, documentation, and a Java-based API 
implementation: http://isweb.uni-koblenz.de/eventmodel
