摘要：Search and navigating the query results on various large databases in different domains often gives a vast number of results in which only a small number of results required by the user. To reduce this information overload problem categorization and ranking techniques were used earlier. Efficient navigation through results categorization and ranking is the focus of the work. In this paper we are using a combined approach of ranking and categorization. In Our approach we are also using a clustering technique that performs offline query processing of all the query results of the users. Later we are using an efficient navigation over these clusters that reduces the navigational cost so that user can easily navigates and match his needs. We are also proposing a generalized Top down approach of efficient navigation of database query results for all databases. We show experimentally that system out performs state of the art categorization system and works well for the data sets in different domains.
