== Agenda & Proceedings ==

* '''Dr. Leo Obrst''' of MITRE, and a co-convener of the Ontolog Forum, will be presenting to the community. His talk is entitled: "'''What is an ontology? - A Briefing on the Range of Semantic Models'''"

:http://ontolog.cim3.net/file/resource/presentation/LeoObrst_20060112/LeoObrst_20060112.png [picture of Dr. Leo Obrst]

: '''Abstract:''' (by LeoObrst)

: '''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.'''

* '''Session Format and Agenda''':
** ''this will be virtual session over a phone conference setting, augmented by shared computer screen support''
## Part-1: The session will start with a brief self-introduction of the attendees (~10 min.)
## Introduction of the Invited Speaker by [[PeterYim|Peter P. Yim]]
## Presentation by the invited speaker (80 min.)
## Part-2: we'll skip introductions and move straight into the continuation of the pressentation (45~60 min.)
## Q & A and Open discussion (~30 min.)

* '''Bio of Dr. Leo Obrst''':

: '''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 <nowiki>VerticalNet.com</nowiki>, 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.
