Adaptive Hypermedia Presentation Modeling for Domain Ontologies

Adaptive hypermedia has become a hot topic as web-based on-line instruction keeps thriving. We propose a framework that supports the definition of dynamic hypermedia presentations without assuming a pre-established approach for pedagogical knowledge representation. In our system authors a) define ontologies that best fit a specific domain or the author’s understanding of the domain, and b) design abstract presentation models associated to knowledge categories. Web pages are generated dynamically from the domain and presentation model, with a strong correspondence between domain structure and the derived hyperspace structure. The system provides explicit support for adaptive presentation constructs, and admits external adaptive navigation mechanisms and user model update strategies.
