Abstract

Search engines history goes back to the field of Information Retrieval, that has gone through a tremendous change over the period of time. Though search Engines have experienced many enhancements in the last few years, the query processing Techniques that the Information Retrieval (IR) Technology relies on are still based on Keywords. It is difficult to formulate queries which are well designed for retrieval purpose. Query Expansion can solve this problem. Query Expansion is normally aimed to form a query into one that is more responsive for Information Retrieval. Though there are many approaches aimed at query expansion, ontology based query expansion has been found to have more advantages compared to the traditional ones. This paper compares the performance of the Traditional query processing methodology with the Domain Independent Ontology based query expansion Methodology.
