1DAML Ontology Interoperation Using Cyc Steve ReedCycorp
2DAML 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 NAICSCycorp is featuring DAML in it’s upcoming release of OpenCyc (this fall).
3DAML 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, NAICSProvide an inference engine for the Semantic Web - subsumption, classification, constraints, well-formed statement validation, diagnostics, justifications.What web services interface? SOAP likely.

7UNSPC/NAICS MappingUniversal Standard Products and Services Classification, North American Industrial Classification SystemBoth 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.
