Retrieving Information based on Ontology Approach

Abstract

The huge number of available documents on the Web makes a challenging task to find relevant ones. The quality of result provided by traditional full-text search engines is still not optimal for many types of user queries. Especially the vagueness of natural languages, abstract concepts, semantic relations and temporal issues are handled inadequately by full-text search. To tackle these problems, ontologies and semantic metadata can be used with the help of meaningful semantic interrelationships. In this approach, a specific domain ontology was built using Resource Description Framework (RDF) and Resource Description Framework Schema (RDFS), and required information was provided with the semantic information of the contents and the relationship of the subconcepts using RDF Data Query Language (RDQL).
