DBS-PSI: a new paradigm of database search

Abstract

Abstract:The advent of the World Wide Web made search engines the most essential component of our everyday life. However, the analysis of information provided by current search engines often presents a significant challenge to the client. This is to a large extent because the client has to deal with many alternatives (solutions) described by contradictory criteria, when selecting the most preferable (optimal) solutions. Furthermore, criteria constraints cannot be defined a priori and have to be defined interactively in the process of a dialog of the client with computer. In such situations, construction of the feasible solution set has a fundamental value. In this paper, we propose a new methodology for systematically constructing the feasible solution set for database search. This allows to significantly improving the quality of search results. 2 R.
