Semantic Knowledge Source Integration: A Progress Report

Semantic Knowledge Source Integration is an ongoing research project at Cycorp which is developing technologies that enable users to integrate structured knowledge sources in a variety of formats with the Cyc Knowledge Base. Once integrated, the contents of the external sources are available to Cyc for question answering as if the source were “part of” the Knowledge Base. In this paper, we give a brief overview of the Semantic Knowledge Source Integration project at Cycorp, discuss its recent, current, and future research directions, and demonstrate the added value of integrating a source with Cyc by showing how Cyc’s inference engine extrapolates knowledge from the source that could not be obtained by querying the source directly.
