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 it’s 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, NAICSProvide 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 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.

• Hardwood International is an online store, selling mainly lumber but offering hardware as well, but NAICS is a monohierarchy.
