Ontology workshop

Abstract

Semantic Web is a World Wide Web where information stored on web content may be read not only by humans but by machines and software. With the Semantic Web, the current web can be evolved by having software agents roaming the web, browsing and searching for information as we human beings currently do. An important factor needed in the semantic web is knowledge representation, understood as using knowledge in order to give meaningful content to a web page. This can be achieved by having logic rules and data in knowledge representations. This is done by using languages like XML and RDF and OWL. These languages are able to define an ontology. This project is proposing an ontology workshop. By ontology workshop it is understood as an ontology toolkit. The toolkit is able to construct ontologies in OWL format. Ontologies are represented graphically. The toolkit is considered as a workshop as it has added functionality including mapping from ER diagrams and similarity measures. The mapping between an ER diagram and ontology is done automated, reducing to the minimal human intervention. The project attempts to find similarity between concepts in ontologies, by using a similarity measure. This measure would be capable of giving a similarity value for two concepts residing in different ontologies. Similarity was conducted by using graph theory. The ontologies were represented as two separate graphs. Using similarity on graphs, the similarity value of two concepts will be computed.
