  1. OntoMap.ORGProject Proposal Atanas Kiryakov OntoText Lab, Sirma AI Ltd. (http://www.OntoText.com)

  2. OntoMap.ORG Project Proposal The Idea Semantic web portal for upper-level ontologies • Host the most popular upper-level ontologies • Provide them in many formats • Make an application server • Map them to each other • Classify them by conformance dimensions OntoMap.ORG Project Proposal

  3. OntoMap.ORG Project Proposal Next Slides • Upper-Level Ontologies • Unified Representation • Formats and Representations, Application Server • The Initial Set of Ontologies • Mappings • The Dream Team • Ontology Unification Services OntoMap.ORG Project Proposal

  4. OntoMap.ORG Project Proposal Upper-Level Ontologies What’s special about them? • Primitive concepts grounded in the common sense • Mostly defined by taxonomic relations • Naturally “light-weight” (according to Rudi Studer) Why? – Try to answer for Table class and Leg slot: • What’s the minimal and maximal cardinality? • What’s the type restriction? OntoMap.ORG Project Proposal

  5. OntoMap.ORG Project Proposal Upper-Level Ontologies (II) It seems standard and universal, right? (picture from OntoTerm) But what about the Stuff/Object distinction? OntoMap.ORG Project Proposal

  6. OntoMap.ORG Project Proposal Unified Representation OntoMapO – a meta-ontology in the spirit of: • A Formal Ontology of Properties (Guarino and Welty, EKAW2000) • Concept Upper Model (CUM in ODE, Gomez-Perez et all.) • the Upper Cyc Ontology primitives • Semantic patterns (according to Rudi Studer) OntoMap.ORG Project Proposal

  7. OntoMap.ORG Project Proposal Formats and Representations • PROLOG, LISP • KIF, Ontolingua • XML (according to OIL and OntoMapO) • RDF(S) • HTML – static pages • HTML – ontology browser • SQL scripts, MDB (Access), DBF (DBase, etc.) OntoMap.ORG Project Proposal

  8. OntoMap.ORG Project Proposal Application Server Online application server providing API for access to the ontologies via: • CORBA • EJB and RMI • SOAP (an RPC protocol based on XML) OntoMap.ORG Project Proposal

  9. OntoMap.ORG Project Proposal The Initial Set of Ontologies • Upper Cyc Ontology [UCYC] • EuroWordnet Top Ontology [ETOP] • EuroWordnet Clusters [ECLUST] • WordNet 1.5 unique beginners [WNUB5] • WordNet 1.6 unique beginners [WNUB6] • CORELEX [CLEX] - made on top of WNUB5 • SIMPLE Core Ontology [SIMC] • SIMPLE Recommended Ontology [SIMR] OntoMap.ORG Project Proposal

  10. UCYC ETOP WNUB6 ECLUST WNUB5 SIMR CLEX SIMC OntoMap.ORG Project Proposal Mappings Agenda: Given (natural/made creation time) Already existing and available To be developed under the project OntoMap.ORG Project Proposal

  11. OntoMap.ORG Project Proposal The Dream Team OntoText Lab. – a coordinator.Members (organizations): • Guru in the ontology design • Lexical knowledge base developer • User of domain specific ontologies • User of lexical knowledge bases OntoMap.ORG Project Proposal

  12. OntoMap.ORG Project Proposal Ontology Unification Services Services for upper-level and domain specific ontologies on top of the OntoMap server: • Loading and hosting an ontology in OntoMap • Available in multiple formats • Clear conformance profile • Public/Private access • Mapping to other ontologies OntoMap.ORG Project Proposal
