Background -Where does it from
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…
NeOn conference, Mar 22-24
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
We and Protégé Ctd.
Functionalities58,676 registered users81 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…
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…
For a Team based ontology construction task…

6: Managing the dynamic status of Domain Ontology, such as the versions control and the transformation among multilingual languages.
5: Integrating concepts and terminologies from other related areas integrating new concepts, attributes and relationships extracted from domain information, to improve domain ontology information.
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.

Multi-user access Efficiency of ontology database management and access Experience similar to desktop applications Capability of protégé collaboration
!Yes, They are TOMS’ objectives
Candidate Techs
Ajax: Asynchronous JavaScript and XML
Comprised by the technology of HTML, JavaScript™, DHTML and DOM.
