Dynamic test generation over ontology-based knowledge representation in authoring shell

Intelligent tutoring systems are kind of asynchronous e-learning systems designed to support and improve learning and teaching process in particular domain knowledge. An authoring shells are kind of e-learning systems that feature authoring environments for System users. Domain knowledge in such systems can be represented by using different knowledge representation specifications and presentation of tests mainly depends on the type of domain knowledge. We propose templates for dynamical generation of questions as a test over previously formalized domain knowledge. In our approach we encourage expressiveness of ontology for describing domain knowledge. Tests described in this paper entails declarative knowledge formalized by Web Ontology Language (OWL) and are realized as a dynamic quiz. By pronouncing OWL ontology as domain knowledge formalism we deal with the problem of generating tests and understanding presentation of the tests. (C) 2008 Elsevier Ltd. All rights reserved.
