    1. 1 Ontology Tools Survey Project Leader : Seongwook Youn Group Members : Anchit Arora Preetham Chandrasekhar Paavany Jayanty Ashish Mestry Shikha Sethi

    2. 2 Introduction Goal Understanding and evaluation of the tools Applicable for all stages of the ontology lifecycle From Creation to Evolution Many tools are still offered as research prototypes Require users to be trained in knowledge representation and predicate logic Standard compliance and support for RDF(S) and OWL is growing Semi-automation is maturing, but collaborative working is still weak

    3. 3 Introduction Ontology development tools Prot�g� 2000, Oiled, Apollo, RDFedt, OntoLingua, OntoEdit, WebODE, KAON, ICOM, DOE and WebOnto Commercial tools Medius Visual Ontology Modeler LinKFactory Workbench K-Infinity

    4. 4 Prot�g� 2000 Developed by Stanford Medical Informatics Extensible plug-in architecture Support Graph view, consistency check, web, merging No support Addition of new basic types Limited multi-user support

    5. 5 OilEd Developed by Information Management Group, CS Dept., Univ. of Manchester, UK Simple editor, not intended as a full ontology development environment Support Consistency check, web No support Graph view, extensibility

    6. 6 Apollo Developed by Knowledge Media Institute of Open University, UK Modeling is based on basic primitives ( classes, instances, functions, and relations) and hierarchical view Support � consistency check No support � graph view, web, multi-user

    7. 7 RDFedt Developed by Jan Winkler, Germany Textual language editor Not Java program, not platform independent, works only on Windows Support Limited consistency check, web, Dublin Core Element Set No support Graph view, multi-user

    8. 8 OntoLingua Developed by Knowledge systems lab., Stanford University Provides a distributed collaborative environment Support Consistency check, web access, multi-user No support Graph view, extensibility

    9. 9 OntoEdit Developed by Ontoprise, Germany 2 versions( Freeware and Professional) Support Graph view, consistency check, web No support Built-in inference engine, DBMS, collaborative working and ontology library

    10. 10 WebODE Developed by Technical University, Madrid Not an isolated tool Support Graph view, consistency check, web, multi-user, merging, extensibility and merging No support Ontology library

    11. 11 KAON Developed by FZI Research Center & AIFB Institute, University of Karlsruhe, Germany Provides two user-level applications: OiModeler and KAON PORTAL Support Consistency check and multi-user No support Graph view, merging

    12. 12 ICOM Developed by Free University of Bozen-Bolzano, Italy Written in Java 1.2, used on Linux & Windows, communicate via CORBA Support Graph view and consistency check No support Multi-user, web and information extraction

    13. 13 DOE (Differential Ontology Editor) Developed by National Audiovisual Institute, France Methodology proposed by Bruno Bachimont Support OWL and DAML+OIL, Interoperability using both RDFS and OWL and consistency check No support Graph view, merging and problems with Dublin Core Metadata

    14. 14 WebOnto Developed by Knowledge Media Institute of Open University, UK Aim of WebOnto is to easy-to-use, yet have scalability up to large ontologies Support Collaborative environment, multiple inheritance, multi-user and consistency check No support Extensibility, merging and online service only

    15. 15 Medius VOM Developed by Sandpiper Software, Inc UML-based modeling tool, add-in to Rational Rose Enterprise Edition Support Web, multi-user, consistency check and graph view No support Information extraction

    16. 16 LinKFactory Workbench Developed by Language and Computing Inc., Belgium Originally designed for very large medical ontologies Support Collaborative environment, consistency check, merging and multi-user No support Graph view

    17. 17 K-Infinity Developed by Intelligent Views, Germany For knowledge network Two different workspaces (graph editor and concept editor) Support RDF, graph view and automatic management of references No support Web and extensibility
