Abstract

Abstract. Domain ontology as an instrument for knowledge representation, sharing, reuse and interoperability takes an increasingly important role in the approaches for personalised intelligent e-learning architectures and systems. However, wider practical acceptance of domain ontology as an engineering product and as a part of web-based learning systems is still needed. We believe that one of the barriers for wider spreading of domain ontologies in different fields, including e-learning, is the problem of the design and maintenance of high quality ontologies. As the importance of the quality of learning resources is obvious, the quality of domain ontology for e-learning is even more important, because ontology is intended to be re-used in design and implementation of various learning resources. In this paper, we analyse the quality-related characteristics of domain ontology. We propose a framework for evaluation of the quality of domain ontology for web-based learning. Further, we propose a model for ontology evaluation, based on its technical and complexity-related characteristics. We identify main conceptual (semantic) quality characteristics, and analyse the relationship between both types of ontology quality characteristics. Also we present an application of proposed framework to the evaluation of ontologies for web based learning.
