Honestly, we were a little pressed for time toward the end of the 
session yesterday. There were a few more slides that Leo could 
have covered, and I'm sure some of the members of the audience 
didn't get their chance to ask questions. I have, since, received 
requests for a follow-up session.    (01)

*Good New!* - I have got this worked out, and Dr. Obrst has 
graciously agreed to set aside 1.5 hours next Thursday 
(2006.01.19) as a Part-2 session of this talk. The session will 
start at the usual time. Call details as follows:    (02)

Date: Thursday, Jan. 19, 2006
Start Time: 10:30am PST / 1:30pm EST / 18:30 UTC (World Time:
Session Duration: 1.5 Hours
Dial-in Number: +1-702-851-3330 (Las Vegas, Nevada, USA)
Participant Access Code: "686564#"
VNC shared-screen support available    (03)

Please refer to other session details on our wiki session page 
(same page as before) at:
[note especially details pertaining to the Part-2 session]    (04)

I suggest we'll just jump straight into the talk without much 
introductions at the front for this upcoming session. That would 
give us more quality time for Dr. Obrst's material, and allow us 
more time for Q&A's and discussion after he finishes on the 
prepared content.    (05)

RSVP to the undersigned at <peter.yim@xxxxxxxx> offline, so that 
I can arrange enough conferencing resources for the session. I 
shall look forward to having you at this Part-2 session.    (06)

Regards.  =ppy    (07)

P.S. If you missed the first part of the talk, you may consider 
catching up by going over the audio archive of the Part-1 session 
which is now available (refer to details in my previous message.)

 >> 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.
 >> *About the Speakers*:
 >> *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 the University of Texas-Austin. He has worked over 
20 years in computational linguistics, knowledge representation, 
and in the past nine years in ontological engineering. Leo is a 
member of the Executive Committee of the National Center for 
Ontological Research (NCOR, http://ncor.us/), and the chair of 
the NCOR Technical Committee. He was a member of the W3C Web 
Ontology Working Group (http://www.w3.org/2001/sw/WebOnt/) that 
developed the Web Ontology Language OWL. He is a member of the 
IEEE Standard Upper Ontology working group 
(http://suo.ieee.org/), the Semantic Web Services Initiative 
(http://www.swsi.org/), the Ontolog community 
(http://ontolog.cim3.net, which he co-founded and which focuses 
on the promotion of ontological engineering and semantic 
technologies), and the W3C Rule Interoperability group. He is a 
member of AAAI, ACL, LSA, and ACM. His research interests include 
semantic interoperability/integration, formalization of context 
for ontology mapping and merging, and formal upper ontologies, 
Semantic Web rules, and the application of formal ontology and 
formal semantics to ontological engineering.
