  1. Designing the Team-oriented Ontology Management System with Ajax Technology Ze Li, Johannes Keizer, Zhong Wang, Margherita Sini, Yelu Zheng The Institute of Sci-Tech Information, Guangdong Academy of Agricultural Sciences (GDAAS-ISTI) Group of Information and Library, Food and Agricultural Organization of United Nations (FAO-GIL)

  2. Outline • Background • Gap identification • Proposal • Candidate technology • System design and development framework • Uncertainties

  3. Background -Where does it from NeOn conference, Mar 22-24 Hi, I’m Ze Li. this paper will give a brief introduction on some related discussions with FAO-GIL colleagues during my visiting Rome in March 2006…

  4. We and Protégé • KAON was introduced in the 5th AOS workshop in Beijing, 2004 ( good, but slow, then dropped) • One domain specialist (Jackie Chen) was trained to use Protégé, and ISTI deployed it in the first collaboration project in 2005(Ontology Conversion and adaptation) • One IT specialist (Ze Li) was trained to apply Protégé to perform some ontology management (Ontology merging, concept structure reengineering) and semantic related trials in 2006

  5. We and Protégé Ctd. • Functionalities • 58,676 registered users • 81 plug-ins (7 types, 13 topics) • Performance (Lack of experimental data) • Resource hungry (memory, CPU) • Net environment? Worse • Team-work on the Net? You tell … We have been working with Protégé for almost two years, it could hardly say that we get alone well with each other…

  6. The Gap • What may happen with the C/S Protégé configuration • Fat-Client end (2M DDR, 2.3GHZ CPU) • Patience required …… • Unexpected exception alert during loading the file • …… Sorry for not collecting enough experimental stuff to support this, but these are the real situations we experienced…

  7. For a Team based ontology construction task…

  8. And need to concern… 1 2 3 6 5 4 4:Auditing the data which are extracted from domain knowledge in the step 3 and editing the precise text definitions for concepts and relationships to clearly define the expressions of these concepts and relationship terminologies. 5:Integrating concepts and terminologies from other related areas integrating new concepts, attributes and relationships extracted from domain information, to improve domain ontology information. 6:Managing the dynamic status of Domain Ontology, such as the versions control and the transformation among multilingual languages.

  9. The environment required by collaborative ontology development … • Functionalities • Ontology management and construction • Team members with different roles • Performance • Quick responses on the Net • Collaborate with existing tools (e.g. Protégé’s plug-ins) • Non-conflict ontology maintenance ?

  10. TOMS Which indicate… • Multi-user access • Efficiency of ontology database management and access • Experience similar to desktop applications • Capability of protégé collaboration ! Yes, They are TOMS’ objectives

  11. Candidate Techs • Ajax: Asynchronous JavaScript and XML • Comprised by the technology of HTML, JavaScript™, DHTML and DOM. • Jesse James Garrett. ajax: a new approach to web applications. http://www.adaptivepath.com/publications/essays/archives/000385.php. • Jena package: Java framework for building Semantic Web applications • Rule-based inference engine included • To store Ontology models in the related databases • Originate from internal projects of HP Lab

  14. System design

  15. Framework Yes, it intend to be developed with Open Source

  16. System Structure

  17. Uncertainties • Pros • Collaborative features • User experience • Prototype need to be developed and evaluated • User interface • Collaboration with Protégé • Multi-user access

  18. Acknowledgement • FAO: AOS Project • Personnel • Ms. Marta Iglesias • Ms. Gauri Salokhe.
