Abstract:
Today, Information Technology (IT) is rapidly improving and then large-scale available data and information is demanded by information society. To get relevant and related information, efficient Information Retrieval (IR) system which is needed provides advanced searching facilities. To organize large information repositories and access these repositories efficiently, metadata can be used. Closely related to metadata is Ontology. Ontology is a formal explicit description of concepts in a domain of discourse, properties of each concept describing various features and attributes of the concept, and restrictions on slots. This paper intended to present the features and benefits of the IR system by applying ontology concepts and also point out how metadata is critical in supporting effective discovery.
