Web databases when queried result in huge number of records when users of query need a portion of those results which are real interest to them. This problem can be solved using concept hierarchies. Knowledge representation in the form of concepts and the relationships among them (Ontology) allows effective navigation. Recently the researcher presented provisions for categorization and ranking in order to reduce the number of results of query and also ensure that the navigation is effective.
