Abstract
In this paper we propose a new modality, denoted by b, which allow preferences in propositional knowledge bases. Formulae with b are interpreted in a weighted propositional calculus. This new modality can be used in order to define a revision operator that satisfy Alchouron, Gärdenfors and Makinson postulates modified by Katsuno et Mendelzon.
