A Flexible Scheme for Representing and Retrieving Multimedia Contents in Computer-Based Educational Systems
نویسندگان
چکیده
Computer based educational systems are faced with an increasing range of challenges. The use of multimedia provides a number of technical and conceptual demands, the volume and nature of the material requires sophisticated knowledge representation techniques, and a continuously increasing level of interactivity between learner and system is desired. This paper suggests a concept for an advanced learning system, which addresses these issues. The concept is based on the Flexible Structured Coding Language, FSCL, a natural language-like, formalised description language. A range of extensions regarding the use of ontologies, inference of knowledge and the formulation of freeform queries based on FSCL are discussed.

متن کاملA semi-automated Framework for Supporting Semantic Image Annotation
Advanced semantic description of multimedia data significantly improves representing, labeling, and retrieving multimedia-based contents. In this paper we present an intelligent framework for attaching semantic annotations to image contents based on the extraction of elementary low-level features, user’s relevance feedback and the usage of ontology knowledge. This approach facilitates image ann...
