Evaluation of domain ontology requirements in e-tutor framework

Abstract

The domain module within Intelligent Tutoring Systems is used to describe the course topics including the knowledge units and competencies.  Ontology is a good solution for knowledge management as it can provide a standardized way and a reasoning engine for the related knowledge management tasks. In this paper, we analyze the functionality of the usual OWL-based ontology construction and set the main requirements to enhance the usability of the ontology knowledge modelling language. Based on these shortcomings, we set the main requirements against an efficient ITS domain ontology description language. This language should be based on simplified Manchester syntax and it should contain additional structural elements too.
