All, (01)
Sorry for the delay on this: here's my introduction. (02)
I am a senior AI scientist at the MITRE AI Center in Northern Virginia
(www.mitre.org) and the technical coordinator for knowledge
representation and semantics, involved in projects on context-based
semantic interoperability, ontology modeling of complex decision-making,
conceptual information retrieval, community metadata and semantic
markup, and semantic mapping/brokering. I was recently Director of
Ontological Engineering at VerticalNet.com, a department I formed to
create ontologies in the product and service space to support
Business-to-Business e-commerce. (03)
My PhD is in theoretical linguistics with a concentration in formal
semantics from the University of Texas-Austin. I have worked nearly 20
years in computational linguistics, knowledge representation, and in the
last seven years in ontological engineering. (04)
I am a member of the W3C Web Ontology Working Group
(http://www.w3.org/2001/sw/WebOnt/) and the IEEE Standard Upper Ontology
working group and am currently the assistant technical editor for one
proposed standard upper ontology candidate, the Information Flow
Framework (http://suo.ieee.org/). In addition, I participate in the
OntoWeb network (http://www.ontoweb.org/index.htm). (05)
My general research interests include formal models, the semantics and
pragmatics of natural language, ontology representation and reasoning,
the Semantic Web, constraint and logic programming, intelligent agents,
and category theory. I am currently most interested in the formalization
of context for ontology mapping and integration, and semantic mapping
methods. (06)
