3. 22-23 Nov. 2000 OntoMap.ORG Project Proposal2 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 The Idea

4. 22-23 Nov. 2000 OntoMap.ORG Project Proposal3  Upper-Level Ontologies  Unified Representation  Formats and Representations, Application Server  The Initial Set of Ontologies  Mappings  The Dream Team  Ontology Unification Services Next Slides

5. 22-23 Nov. 2000 OntoMap.ORG Project Proposal4 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? Upper-Level Ontologies

6. 22-23 Nov. 2000 OntoMap.ORG Project Proposal5 It seems standard and universal, right? (picture from OntoTerm) Upper-Level Ontologies (II) But what about the Stuff/Object distinction?

7. 22-23 Nov. 2000 OntoMap.ORG Project Proposal6 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) Unified Representation

8. 22-23 Nov. 2000 OntoMap.ORG Project Proposal7  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.) Formats and Representations

9. 22-23 Nov. 2000 OntoMap.ORG Project Proposal8 Online application server providing API for access to the ontologies via:  CORBA  EJB and RMI  SOAP (an RPC protocol based on XML) Application Server

10. 22-23 Nov. 2000 OntoMap.ORG Project Proposal9 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 ]

11. 22-23 Nov. 2000 OntoMap.ORG Project Proposal10 OntoMap.ORG Project Proposal Mappings Agenda: Already existing and available To be developed under the project Given (natural/made creation time) ETOP ECLUST UCYC CLEX WNUB5 WNUB6 SIMR SIMC

12. 22-23 Nov. 2000 OntoMap.ORG Project Proposal11 OntoMap.ORG Project Proposal 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 The Dream Team

13. 22-23 Nov. 2000 OntoMap.ORG Project Proposal12 OntoMap.ORG Project Proposal 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 Ontology Unification Services
