DAML Ontology Interoperation Using Cyc Steve Reed Cycorp
DAML Excitement at Cycorp Promoting DAML ontology interoperability through Cyc, as a reference ontology. Cyc now imports and exports DAML, paraphrases and reasons about it. Cyc lexical tools assist the mapping of imported DAML ontologies into Cyc. Both UDDI categorization schemes imported as DAML into Cyc: –UNSPSC (via KSL) and NAICS Cycorp is featuring DAML in its upcoming release of OpenCyc (this fall).
DAML Challenges at Cycorp How to automate mapping and translation of DAML ontologies. How to get the user community to help map numerous DAML terms -- interest growing at OpenCyc. Importation of large DAML schema is daunting but underway, WordNet, OpenDirectory, UNSPSC, NAICS Provide an inference engine for the Semantic Web - subsumption, classification, constraints, well-formed statement validation, diagnostics, justifications. What web services interface? SOAP likely.

UNSPC/NAICS Mapping Universal Standard Products and Services Classification, North American Industrial Classification System Both business taxonomies are monohierarchies, entities should have one code assigned for them. Cyc: #$MonohierarchyClassificationSystem implies that each collection is #$partitionedInto its narrower terms. Mapping is targeted at facets of the reference Cyc terms via functional composition.
