Design And Implementation Of Ontology Editor Based On Silverlight Technology

The ontology building can't do without the support of tools. The ontology has been a hot research point as the widespread use in many fields, such as artificial intelligence (AI), semantic web, electronic commerce, information retrial and extraction and so on. And a lot of ontology build out tools appear. All kinds of ontology edit tools have their own strengths and certain shortages as well. We are lacking in a predominantly tool which is widely approved by the domain experts and ontology researchers.The main problems of current ontology edit tools are including those the owl description languages used by different tools are not compatible, and most of the tools store the ontology contents using documents, only few supports database storage and most of the tools don't support ontology reuse and distributed development.On account of the shortages of the present ontology edit tools and conforming to the development tendency of the tools, this paper is introducing the design and implementation of an ontology editor based on rich client. This system mainly implements the ontology graphic browsing and edits functions. The main work of this paper contains:Summarize the related theories of ontology and the current ontology research situation. Then the paper discusses the necessity of creating new ontology edit tool by analyzing the current ontology edit tools.Summarize and analyze the ontology description languages adopted by the current ontology edit tools. By comparing their shortages and strengths, we choose the web ontology language OWL. It has wide applicability using standard ontology description language to create ontology.Introduce the whole structure and functions of the system and the ontology database building in detail. Realize the functions of graphic browsing and editing. The graphic expression is richer. Users can drag the graphics, unfold and fold the class graphics. When you unfold the class graphic, it shows the details of the class, including properties, kinds of relationships and operations. And when you fold the class graphic, it only shows the class name. We also realize the multi-view browsing. It can show the graphics view and the ontology description document view at the same time. The ontology edit function includes creating and details editing and so on.
