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.

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.
