On some classes of fuzzy information relations

Abstract

Recently, E. Orlowska (1999) has proposed a many-valued generalization of modal information logics which are logical systems for reasoning from incomplete and many-valued information. Following her ideas, we consider a fuzzy generalization of some information relations. We provide basic properties of these relations and their characterizations formalized by means of fuzzy relational operators. For particular classes of fuzzy information relations the corresponding classes of fuzzy information logics are defined and briefly discussed.
