A Fuzzy Dynamic Belief Logic

Abstract

This paper introduces a new logic approach to reason about the dynamic belief revision by extending wellknown Aucher's dynamic belief revision approach to fuzzy environments. In our system, propositions take a valuation in linguistic truth term set, and a belief revision is also in a qualitative way. Moreover, we reveal some properties of our system in epistemic style and do a comparison between our fuzzy belief system with famous AGM postulats.
