Abstract: There are two issues of ontology building and
evaluating: 1) ontology construction is apart from ontology
evaluation; 2) current methods more or less overlooked the role
of ontology end-user. Our contribution is that this paper
proposes a Web-based ontology development framework, with
domain experts, ontology engineers and end users to participate
in it, which emphasizes on the continuity between ontology
building and evaluating process and the importance of usercentric.
Its structure, work principle and three key factors about
implement were particularly discussed. Compared with the past
ontology development method, the framework makes full use of
information diversity, functional diversity and breadth of
audience of the Web, and emphasizes the user-centered concept
of ontology development
