is opencyc doomed to be the new esperanto, or is oor doomed to be the new electronic data...

Is OpenCyc doomed to be the new Esperanto, or is OOR doomed to be the new Electronic Data Interchange, or -- even worse -- both!

What we’d want a good host to provide

Given the other, funded, open ontology repository projects going on in the world (e.g. OKKAM), does it need one more?

Our Content

OpenCyc (www.opencyc.org)The Cyc Ontology made 100% freely available (yes, 100% free even for commercial purposes)Available for download on SourceForgeOver 30,000 “users”

ResearchCyc (researchcyc.cyc.com)OpenCyc + millions of hand-engineered assertionsFree for R&D purposes Current users: 300 research groups (1/2 academic)

What are people doing with it?

• USAF 45th Space Wing: Decision Support• USNavy: Threat Scenario Detection• US Forest Service: Regulatory Compliance• LarKC: Large Knowledge Collider• Medical Research Center: Clinical Trial Cohort Selection (doctors can now directly formulate complex FOPC queries via interactive clarification dialogue; DBs)• Glaxo: semi-automatic ontology alignment across multiple large domain-specific info sources

What We’d Want a Good Host to Provide

A commitment to use – to have contributors all provide content under – some Creative Commons license, as opposed to e.g. a GNU license

Retention of the provenance/lineage of contributed ontological content

Agreement on some of the most fundamental ontological relations

Agreement on a small set of inter-ontology alignment relations

Given the other, funded, open ontology repository projects going on in the world (e.g. OKKAM), does it need one more?

OKKAM is already a funded UE FP7 project (~$10M, 3-years) that started 2 months ago. Ontologizing individuals (including organizations such as the USArmy and IBM as individuals), providing a unique identifier and agreed-on set of properties for each individual

DBpedia extracted the content of fact boxes from Wikipedia + 35 open-source ontologies; KBpedia EU STREP ($3M) follow-on and will include true ontology-merging

Lots of other projects which other speakers in this panel will no doubt mention
