Ontologies,
Ontolingua, and the Knowledge Sharing stack
In the early 1990's, a group of
AI and DB groups got together to define a standard
architecture stack for allowing intelligent systems to
interoperate over a knowledge bus and share data, models, and
other knowledge without sharing data schema or formats. Tom
was part of a collaborative team comprised of colleagues from
different institutions and companies, and he co-led the effort
for the part of the stack related to ontology sharing. He established
the DARPA
Knowledge Sharing Library, a web-based public exchange
for ontologies,
software, and knowledge bases. He gets
cited a lot for clarifying a
definition of ontology for the AI community and for promoting
the vision of ontologies as enabling technology for the Semantic
Web.
