Ontology-Based Adaptive presentation for Course Management System

Abstract

Course management systems (CMS) require flexible supports for the modeling of multimedia content models. Many CMS provide the synchronized, sequential or concurrent, and possible interactive, transfer of streams multimedia data such as audio, video, text and annotations using with network facilities. However, we investigated the exist standards and applications for multimedia documents models such as HTML, MHEG, SMIL, HyTime, RealPlay and MS Windows Media. These content model standards and media applications didn’t provide adequate supports for adaptation presentation facility and fundamental semantic. Consequently, we proposed an ontology-based approach for the modeling of reusable and adaptable multimedia content. We developed a comprehensive system for advanced multimedia content production: support for recording the presentation, retrieving the content, summarizing the presentation, weaving the presentation and customizing the representation. This approach significantly impacts and supports the multimedia presentation authoring processes in terms of methodology and commercial aspects.
