Semantic Information Retrieval Based on Domain Ontology

Abstract

Most of the current search engines are based on the keyword search and it returns a large amount of irrelevant information in response to the user query. This is because of the keyword matching does not consider the semantics of the keyword term. Ontology has been increasingly used to efficiently capture the semantics of the information which overcomes the problems associated with traditional keyword search. The importance of ontology is identified in the area of building semantic information retrieval systems for the specific domain and gains greater significance over the tradition keyword search.
