ABSTRACT

Ontologies are formal theories that are suitable for implementing the semantic web, which is a new technology that attempts to achieve effective retrieval, integration, and reuse of web resources. Ontologies provide a way of sharing and reusing knowledge among people and heterogeneous applications systems. The role of ontologies is that of making explicit specified conceptualizations. In this context, domain and generic ontologies can be shared, reused, and integrated in the analysis and design stage of information and knowledge systems. This study aims to design an ontology for international organizations, and build an Internet web retrieval system based on the proposed ontology, and finally conduct an experiment to compare the system performance of the proposed system with that of Internet search engines focusing relevance and searching time. This study found that average relevance of ontology- based searching and Internet search engines are 4.53 and 2.51, and average searching time of ontology-based searching and Internet search engines are 1.96 minutes and 4.74 minutes.
