*REMINDER*    (01)

Happy New Year, everyone!    (02)

This long anticipated session on "What is an ontology?" is coming 
up in a few days. Whether you are just trying to find out for the 
first time, or if you are a seasoned software professional, 
system designer, librarian, knowledge engineer, taxonomist or 
ontologist, there are good reasons why you shouldn't miss the 
session!    (03)

RSVP (if you haven't already) ... we're looking forward to having 
you at the session.    (04)

Regards.  =ppy

> Session Duration: 2 Hours
> Dial-in Number: +1-702-851-3330 (Las Vegas, Nevada, USA)
> Participant Access Code: "686564#"

> Topic: *What is an ontology? - A Briefing on the Range of Semantic Models*
> *Abstract*:
> The Ontology Spectrum describes a range of semantic models of increasing 
> expressiveness and complexity: taxonomy, thesaurus, conceptual model, 
> and logical theory.
> This presentation initially describes the Ontology Spectrum and 
> important distinctions related to semantic models, e.g., the distinction 
> among term, concept, and real world referent; the distinction among 
> syntax, semantics, and pragmatics; the distinction between intension and 
> extension; and de facto distinctions that the ISO 11179 standard makes 
> (as do many others): data objects, classification objects, terminology 
> objects, meaning objects, and the relationships among these.
> The individual semantic model types are then discussed: weak and strong 
> taxonomies, thesauri, and weak and strong ontologies (conceptual model 
> and logical theory, respectively). Each of these are defined, 
> exemplified, and discussed with respect to when a more expressive model 
> is needed.
> If time permits, semantic integration and interoperability are discussed 
> with respect to the models.
> Finally, a pointer to an expansion of the logical theory portion of the 
> Ontology Spectrum is given: the Logic Spectrum, which describes the 
> range of less to more expressive logics used for ontology and knowledge 
> representation.

> *Dr. Leo Obrst* is a principal artificial intelligence scientist at 
> MITRE’s (http://www.mitre.org) Center for Innovative Computing and 
> Informatics, where he leads the Information Semantics group (semantics, 
> ontological engineering, knowledge representation and management), and 
> has been involved in projects on Semantic Web rule/ontology interaction, 
> context-based semantic interoperability, ontology-based knowledge 
> management, conceptual information retrieval, metadata and thesaurus 
> construction for community knowledge sharing, intelligent agent 
> technology, and ontology-based modeling of complex decision-making, He 
> was recently Director of Ontological Engineering at VerticalNet.com, a 
> department he formed to create ontologies in the product and service 
> space to support Business-to-Business e-commerce. Leo's PhD is in 
> theoretical linguistics with a concentration in formal semantics from
