(945) AN ONTOLOGY EDITOR: CREATING CONCEPT MAPS FOR SEMANTIC WEB BASED E-LEARNING SYSTEMS

摘要

Ontologies play a significant role on Semantic Web based E-learning systems. This paper presentsthe development of an ontology editor. The main function of the editor is to create concept mapsintegrated with a ranking tool enabling running mathematical queries on the maps. An E-learningsystem built on ontology maps and semantic web tools offers unique capabilities such as evaluatingthe level of student's understanding and making content suggestions. In order to achieve this ultimategoal the first step is to create an ontology editor. While developing the editor, there are challenges thatneed to be explored in this study: Which concepts should be suggested when a subject is notunderstood? Is it possible to create mathematical models to determine concepts? What are thetechnical requirements to implement mathematical models in ontology maps? What are theadvantages and disadvantages of storing concept maps in different environments such as XML andGraph Database? What is the feasibility of using query tools such as SPARQL, SQL and Cypher tointegrate mathematical models with concept maps? This paper explores the answers to thesequestions and includes some examples with future directions.
