   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, NAICS

Provide an inference engine for the Semantic Web -
subsumption, classification, constraints, well-formed
statement validation, diagnostics, justifications.
What web services interface? SOAP likely.

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.

       mainly lumber but offering hardware as well, but
