  1. What We’d Want a Good Host to Provide Doug Lenat Cycorp Doug@cyc.com • 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 Content that Cycorp could provide to be be hosted: * OpenCyc (www.opencyc.org) 100% free even for commercial purposes * ResearchCyc (researchcyc.cyc.com) free for R&D purposes In both cases, there are ontologies plus inference engines and API-level and graphical interface tools Meta-level message: Look at OKKAM, LarKC, etc., and decide what role, if any, OOR can/should play, and how it should tie in with those other efforts.

  2. What’s in OpenCyc Explicitly: 300k terms; 14k predicates; 57k classes; 2 million assertions Implicitly: There are infinitely more nonatomic terms and inferred assertions More subtle but crucial point: There are infinitely many contexts (microtheories) defined compositionally rather than having only explicitly reified contexts • (#$isa 596215) • (#$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) • (#$synonymousExternalConcept13916) This means there are 596k “isa” assertions in OpenCyc E.g., mapping between a term in OpenCyc and a WordNet synset
