The aim of Semantic Web is to provide distributed information with
well-defined meaning, understandable for humans as well as machines.
E-learning is an important domain which can be benefited from the Semantic
Web technology. Ontologies, as a building structure of Semantic Web, will
fundamentally change the way in which e-learning systems are constructed. The
explicit conceptualization of system components in a form of ontology
facilitates knowledge sharing, knowledge reuse, communication and
collaboration among system components, and construction of intensive and
expressive systems. In previous research, we implemented tutoring system
named Protus (PRogramming TUtoring System) that is used for learning basic
concepts of Java programming language. Protus uses principles of learner
style identification and content recommendation for course personalization.
The new version of the system called Protus 2.0, supported by several
ontologies, as well as examples of its usage for performing personalization
are presented in this paper. Architecture of new system extends the usage of
Semantic Web concepts, where the representation of each Protus 2.0 component
is made by a specific ontology, making possible a clear separation of the
tutoring system components and explicit communication among them.
