Semi-Automatic Merging of Ontologies using Protégé

Abstract

Ontologies play a crucial role in bringing the Semantic Web vision to its full potential. Ontologies are developed at different levels of abstraction and by different people for various purposes. Knowledge represented by the ontologies is scattered because of existence of many ontologies representing the same concepts, therefore it becomes difficult to analyse, study and use the knowledge spread across many ontologies if they are studied individually. Knowledge represented by ontologies can be combined into a single ontology which is shown in this paper. Ontologies can be merged to combine the knowledge from different ontologies. In this paper we have shown the merger of two ontologies first ontology is university second ontology is the Student profile ontology containing details of Student which were developed in educational domain. Ontologies were developed and merged using protégé 4.0 alpha tools.
