Belief change and pre-orders: a brief overview
Abstract:This paper deals with iterated belief change. Epistemic states are suitable to represent an intelligent agent's knowledge. Most of the time, when dealing with geographic information, the agent faces incomplete, uncertain, or inaccurate information and needs a mechanism for either revision, update, or fusion to handle their change in beliefs in the presence of new items of information. After some preliminaries on the representation of epistemic states by means of pre-orders, the paper presents three approaches to belief change: revision, update, and fusion. For each of these approaches, the background, postulates, representation by pre-orders, and semantic and syntactic requirements are given. In each case, the approaches are illustrated by examples.
