A generic presentation modeling system for adaptive web-based instructional applications

We propose a generic presentation system for adaptive educational hypermedia that is highly independent from domain knowledge representation and application state management. Generality is achieved by providing a framework for the definition of ontologies that best fit specific domains and/or authors. Presentations are described in terms of ontology object classes and relations. An explicit presentation model, separate from course contents, is used to provide course designers with extensive control over the generation of all aspects of presentation, at a moderate development cost.
