Bipolar Queries: An Approach and its Various Interpretations.
Sławomir Zadrożny, Janusz Kacprzyk · European Society for Fuzzy Logic and Technology Conference · 2009
The concept of a bipolar query is studied in the framework of the flexible fuzzy querying of databases. The focus is on the aggregation of the negative and positive conditions forming a bipolar query. Three formal logical representations of such an aggregation are proposed and analyzed taking into account various possible interpretations of fuzzy logical connectives. The relation to other approaches known in the literature is shown. Keywords— aggregation operators, bipolar queries, flexible queries, fuzzy logic, logical connectives modeling.
