  1. Is OpenCyc doomed to be the new Esperanto, or is OOR doomed to be the new Electronic Data Interchange, or -- even worse -- both! Doug Lenat Cycorp • Our content • 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?

  2. Our Content • OpenCyc (www.opencyc.org) • The Cyc Ontology made 100% freely available (yes, 100% free even for commercial purposes) • Available for download on SourceForge • Over 30,000 “users” • ResearchCyc (researchcyc.cyc.com) • OpenCyc + millions of hand-engineered assertions • Free for R&D purposes • Current users: 300 research groups (1/2 academic)

  3. 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

  4. What’s in OpenCyc Explicitly: 300k terms; 14k predicates; 57k classes; 2 million assertions; infin. more nonatomic terms and inferred assertions • (#$isa 596215) • (#$genls 99198) • (#$disjointWith 6114) • (#$resultIsa 4277) • (#$resultGenl 1206) • (#$argIsa 35617 • (#$argGenl 5398) • (#$arg1Isa 16748) • (#$arg1Genl 2354) • (#$arg2Isa 14114 • (#$arg2Genl 2283) • (#$arg3Isa 3486) • (#$argFormat 5493) • (#$arg2Format 3320) • (#$functionalInArgs 1427) • (#$arity 16416) • (#$arityMin 958) • (#$comment 57305) • (#$genlPreds 7440) • (#$negationInverse 990) • (#$genlMt 26078) • (#$denotationInEnglish 409745) • (#$synonymousExternalConcept 13916)

  9. 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

  10. 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
