An Online Ontology Navigator for Web Applications in Education

We have developed a tree-view browser to support development of information retrieval applications that utilize ontologies. The purpose of this browser is to shield the complexity of an ontology from the users. We have also reported three ontology-based Web applications in education and training. The scope of these applications is to cover the daily activities of instructors and trainers. For example, a professor can create highly customized study guides using a bioinformatics ontology, a trainer can define the training needs for a specific task based on a network security ontology, and a domain expert can generate the Web forms for specialized training based on a METOC ontology. These applications were developed using our tree-view browser. The reuse of the browser component has significantly reduced efforts in the development.
