Efficient content creation on the semantic web using metadata schemas with domain ontology services

Abstract

Metadata creation is one of the major challenges in developing the Semantic Web. This paper discusses how to make provision of metadata easier and costeffective by an annotation editor combined with shared ontology services. We have developed an annotation system supporting distributed collaboration in creating annotations, and hiding the complexity of the annotation schema and the domain ontologies from the annotators. Our system adapts flexibly to different metadata schémas, which makes it suitable for different applications. Support for using ontologies is based on ontology services, such as concept searching and browsing, concept URI fetching, semantic autocompletion and linguistic concept extraction. The system is being tested in various practical semantic portal projects. © Springer-Verlag Berlin Heidelberg 2007.
