Ontology-based Framework for User Model Interoperability in Distributed Learning Environments

Abstract

This paper presents an update of our work on developing a distributed architecture for adaptive E-Learning. We introduce ADAPT – an extension of KnowledgeTree architecture that was presented at one of the past E-Learn conferences. To accommodate a larger variety of adaptive components, ADAPT employs a higher-level mechanism for ontology-based interoperability of self-contained adaptive Web-based systems within our architecture. We provide an overview of ADAPT, argue for the importance of ontology-based interoperability, and describe our implementation of this functionality in ADAPT.
