Abstract

In the line of some earlier work done on belief dynamics, we propose an abstract model of belief propagation on a graph based on the methodology of the revision theory of truth. A set of postulates is proposed, a dynamic language is developed for portraying the behavior of this model, and its expressiveness is discussed. We compare the proposal of this model with some of the existing frameworks for modelling communication situations.
