Ontology of SCIENCE
This is a slightly improved version of the KA² ontology developed by
Knowldge Annotation Initiative of the
Knowledge Acquisition Community. The original ontology is available at the
KA² portal, coded in
F-Logic, DAML
and OIL and on the Spanish mirror
of the Ontolingua, under login "ontologias-ka2" and password
"adieu007". Papers describing it can be found in both sites.
I developed this ontology as a domain testbed for a multi-agent system architecture (to
be published in SSGRR-2001) to
search, classify pages and extract information from them that correspond to classes of the
ontology. Although I decided to organize a science ontology prior to finding KAČ
ontology, I could benefit from the reuse of ontologies, one of the good advantages of
employing them.
I made minor modifications along all of it, particularly asserting new inverse
relations and trying to assign the correct allowed classes for the relations, but at least
two changes deserve comments.
The first one relates to publications. Instead of having a single class for
publications with subclasses book, article, etc, I created two sub classes:
- Dividable-Publication, which contatins publications that can be divided, with
subsclasses Book, Journal, Proceedings and Magazine, and
- Part-Publication, with publications that appears as part of the Dividables, like
Journal-Article, Conference-Article, Book-Chapter, etc.
The other modification concerns the class Events, which is now divided on
Scientific-Event and Educational-Event. I assumed that Scientific-Events are the ones
which have scientific committees and deadlines, and Educational Events are the ones in
which courses are given.
In making these two modifications I aimed at allowing for a better understanding of
some classes like Journal, which is a publication but also an event (it has a committe and
deadline) and School (seen as an event), which inherits from both Scientific-Event and
Educational-Event.
It includes (and depends upon) two very simple ontologies of time and locations that
may be substituted by more adequate ones.
