REVIEW ON ONTOLOGY BASED TECHNIQUES IN INFORMATION RETRIEVAL SYSTEMS

Abstract

Information Retrieval [IR] is a method used for searching documents, searching information contained by documents, and for searching metadata about documents, and also for relational databases searching and the World Wide Web (WWW). There stands similarity in the usage of the terms such as data retrieval and document retrieval as well as information retrieval and text retrieval, but each of these has its own body of literature survey, philosophy, and technologies. The ontologies have been established for local information sharing and are widely used as a means for conceptually structuring domains of interest. The aim of semantic web research is to permit the enormous range of webaccessible information and services to be more efficiently exploited by either humans or automated tools. To assist this process, RDF and OWL have been established as standard formats for the sharing and integration of data and knowledge. Different methodologies are there for information retrieval based on ontology from which review of some methodologies is presented in this paper
