Amara,
Cycorp is taking the semantic integration approach that you describe. We
are participants in the DARPA DAML project and I am adapting a DAML Query
Language (DQL) java component written by Stanford to provide a DQL
facility for OpenCyc.
Likewise this year we have a team of programmers working on generalized
semantic integration of relational databases. The objective of our work
is to make structured information from databases and web services appear
to be Cyc assertions for the purpose of deductive inference.
We have demonstrated success in using the Cyc ontology as reference
ontology for mapping a wide variety of external schema and ontologies. We
are demonstrating this ability within the DARPA GENOA II program with our
Terrorism Knowledge Base, which is Cyc greatly augmented by
terrorism-related assertions and mapped/integrated external structured
terrorism sources.
