<ul><li>Slide 1</li></ul> <p>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 wed 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? Slide 2 2 Our Content OpenCyc (www.opencyc.org)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&amp;D purposes Current users: 300 research groups (1/2 academic) Slide 3 3 What are people doing with it? USAF 45 th 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 Slide 4 4 Whats in OpenCyc (#$isa 596215) (#$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) Explicitly: 300k terms; 14k predicates; 57k classes; 2 million assertions; infin. more nonatomic terms and inferred assertions Slide 5 5 Systems and Processes lifetime of system energy source boundary resource conveyer resource synthesizer providerOfMotiveForce doneBy transporter eventOccursAt Slide 6 6 FunctionalSystem Specializations AutocatalyticProcess Ecosystem EcologicalProcess Organization Organism Culture-Practice Metabolism componentInSystem agentInEcosystem hasMembers anatomicalParts Slide 7 7 Ecosystem Classes Ecosystem Biome Aquatic Life Zone Desert Ecosystem Tropical Rainforest Ecosystem Chaparral Ecosystem Tundra Ecosystem Taiga Ecosystem Grassland Ecosystem genls Slide 8 8 Chaparral Ecosystem Mediterranean Climate Cycle climateOfEcosystemType Mediterranean Scrub terrainClimateType Geographical Region Eco- system genls Territory Of Santa Barbara, CA hasClimateType Slide 9 9 What Wed 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 Slide 10 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 Slide 11 11 Slide 12 12 FP7 IP - LarKC Consortium OrganisationCountry Universitt InnsbrukAustria AstraZenica AB, R&amp;DSweden CEFRIEL S.c.r.l.Italy Cycorp, Raziskovanje in Eksperimentalni Razvoj, d.o.o.Slovenia Universitt Stuttgart, HPCCGermany Max Plank GesellshaftGermany Sirma Group, Ontotext LabBulgaria SaltluxKorea Siemens AktiengesellshaftGermany University of SheffieldUnited Kingdom Vrije Universiteit AmsterdamNetherlands Beijing University of TechnologyPRC WHO: International Agency for Research on CancerFrance Slide 13 13 Slide 14 14 </p>
