Abstract:
Requirements elicitation for a multimedia presentation system for e-learning led the writers to propose a video segmentation process that adapts learning materials through online interventions between the student and tutor. The tutor tailors audio/visual segments by dynamically inserting new fragments that provide supplementary updates in response to questions from students. A survey of advanced adaptive approaches revealed that processing of manually or automatically generated metadata would provide better adaptation. Automated use of metadata requires storage and processing of context dependent ontology hierarchies that describe the semantics of the curriculum. Data and semantic models needed to adaptively process multimedia presentations in real-time are derived. The design models are implemented using HTML, XML and Flash. The authors conclude that the use of context-based rules that process meta-level descriptions of segmented multimedia components stored according to a bounded ontology can produce a system that dynamically adapts learning materials.
