Peter:
I've just been listening to the mp3 file of last week's call, and deeply
regret not being able to have been there. I must also give my apologies for
today's part2 follow-up call, as I will not be able to participate either:
it's a bad time of day for me calling from Vienna, Austria, but at least I
can follow asynchronously...! Hope to have more opportunities to participate
at future meetings... (01)
Best regards, (02)

> >>
> >> *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.
