The provision of content, especially information, is one of the most important lifelines in the current information society. It is a fundamental process of the current information society multimedial knowledge is presented on Web pages, virtual objects are visualized in Virtual Reality applications, Web services are used in business processes and e-Learning content can be learned in educational systems. Especially the provision of information content is targeted in this work. It is the step of the information life cycle where its value is at highest (Tallon and Scannell, 2007). It is necessary to pre-select, prepare and provide them in adequate ways to the user. Especially for e-Learning this is a tremendous venture. It was the aim of this chapter to propose semantic technology approaches in order to enable the usage of didactical expertise as well as adapted content provision. Semantic Web technologies, especially ontologies, are seen as the key approach with tremendous potential to future applications (Hendler, 2008). They "fit so well with education, by building a strong platform for it, by bringing reflection and by interweaving everything." (Devedzi, 2006). In this chapter and the referenced literature, numerous approaches are described that fundamentally base on Semantic Web technologies in order to enhance selected aspects of eLearning. Ontologies were for example used for the description of didactical expertise, course definitions, learning content recommendations, course enrichment, quality driven content selection to name only a few. |
