TITLE Belief Revision by Sets of Sentences: A General Framework for Belief Revision AUTHOR
نویسندگان
چکیده
The aim of this paper is to extend the system of belief revision developed by Alchourr on, G ardenfors and Makinson (AGM) to a more general framework. This extension not only enables a treatment of revision by single sentences but also by any sets of sentences, especially by in nite sets. The extended revision and contraction operators will be called general ones, respectively. A group of postulates for each operator is provided in such a way that it coincides with AGM's in the limit case. A notion of the nice-ordering partition is introduced to specify the general contraction operation. A constructive approach is provided for belief revision operations.

Explanations, belief revision and defeasible reasoning
We present different constructions for non-prioritized belief revision, that is, belief changes in which the input sentences are not always accepted. First, we present the concept of explanation in a deductive way. Second, we define multiple revision operators with respect to sets of sentences (representing explanations), giving representation theorems. Finally, we relate the formulated operato...
متن کاملConsiderations on a Similarity-Based Approach to Beleif Change
A foundational approach to modell ing belief contraction and revision is presented, based on a notion of similarity between belief sets. In contracting from a belief set, the result is the belief set(s) most similar to the original in which is not believed; similar considerations apply to belief revision. The modell ing of belief change generalises the Grove modell ing based on a system of sphe...
متن کاملBelief Change as Propositional Update
This study examines the problem of belief revision, defined as deciding which of several initially accepted sentences to disbelieve, when new information presents a logical inconsistency with the initial set. In the first three experiments , the initial sentence set included a conditional sentence, a non-conditional (ground) sentence, and an inferred conclusion drawn from the first two. The new...
متن کاملTowards a ‘sophisticated’ model of belief dynamics
It has been often noted that classical models of belief do not accurately represent the limits of human doxastic capacity, at least if belief is understood in a sufficiently internal sense. This is equally true of models of belief revision (Hansson, 2003). Furthermore, Rott (2004) has recently raised doubts about several of the most important of Gärdenfors postulates relating to belief revision...

Part I of this paper Rott has argued that doxastic states should be repre sented as revision functions that take sequences of sentences of arbitrary nite length as arguments and return belief sets that is sets of sentences closed under some background logic Cn as a result We have interpreted the well known rationality postulates for belief change given by Alchourr on G ardenfors and Makinson an...
