Mapping Ontologies into Cyc

Mapping Ontologies into Cyc- By Stephen L. Reed and Douglas B. Lenat, Cycorp Inc., Austin, USA, 2002. The authors present the process by which several ontologies have been mapped or integrated with Cyc, a large commonsense knowledge base, over 15 years. ODP was among the chosen ontologies but was removed because the constant enhancements in the directory created a high maintenance burden.
