Abstract

Abstract - There is a boost in the interest on ontology with the developments in Semantic Web technologies. Ontologies play a vital role in semantic web. Even though there is lot of work done on ontology, still a standard framework for ontology engineering has not been defined. Even though current ontology engineering methodologies are available they need improvements. The effort of our work is to integrate various methods, techniques, tools and etc to different stages of proposed ontology engineering life cycle to create a comprehensive framework for ontology engineering. Current methodologies discuss ontology engineering stages and collaborative environments with user collaboration. However, discussion on increasing effectiveness and correct inference has been given less attention. More over, these methodologies provide little discussion on usability of domain ontologies. We consider these aspects as more important in our work. Also, ontology engineering has been done for various domains and for various purposes. Our effort is to propose an iterative and incremental approach for ontology engineering especially for e-learning domain with the intention of achieving a higher usability and effectiveness of e-learning systems. This paper introduces different aspects of the proposed ontology engineering framework and evaluation of it.

Highlights

  • Interest in researchers on ontology engineering has increased in last few years

  • Semantic Web can be seen as an extension of the current Web, aimed at augmenting the information with well-defined semantics, to enable computers and people to work in cooperation [1]

  • One of the prime objectives of the Semantic web is to define Web resources and the relationships between them at a conceptual level. In this task knowledge structures intended at the conceptual level such as ontologies play a major role

Summary

INTRODUCTION

Interest in researchers on ontology engineering has increased in last few years. One of the main reasons for this is the rapid evolution of Semantic Web. One of the prime objectives of the Semantic web is to define Web resources and the relationships between them at a conceptual level In this task knowledge structures intended at the conceptual level such as ontologies play a major role. The objective of this paper is to propose an enhanced ontology-engineering framework to develop ontologies in the e-learning domain. It is not practical to build an ontology in a single giant step, it has to be done in a set of phases. In this process, the ontology engineering happens in an iterative and incremental fashion seamlessly.
