Re: Core Ontology on Events -- Re: looking for an event ontology/vocabulary

Dear All,

I was abroad these last weeks, and unable then to follow this thread 
with the necessary attention. It seems however evident to me that, when 
dealing contemporaneously with terms like "ontology" and "event", one 
should have at least a look at NKRL (Narrative Knowledge Representation 
Language). NKRL is, in fact, a language and software environment 
expressly created for dealing in a somewhat 'intelligent' way with 
"narratives", i.e., in practice, with streams of (complex) events.

To do this, NKRL makes use of two different ontologies, a 'standard' 
(binary) one for dealing with 'static notions' like, among other things, 
"objects and persons participating in events", and an n-ary one for 
describing general classes of events like "moving an object", "making a 
trip", "starting a company", "having a positive/negative attitude 
for/against someone/something", "living in a place", "receiving some 
money", "feeling ill" etc. Of course, NKRL is also endowed with all sort 
of conceptual tools to represent temporal information and event 
correlations ("connectivity phenomena"), and with high-level inference 
tools. Interested people can consult my recent (Springer, 2009) book on 
this subject: "Representation and Management of Narrative Information - 
Theoretical Principles and Implementation", see 
http://www.springer.com/computer/artificial/book/978-1-84800-077-3 or, 
for an introduction, my paper at the "2009 AAAI Spring Symposium on 
Intelligent Complex Event Processing//" in Stanford.
