A First Approach to Multiple Credibility Limited Belief Base Revision

Belief revision deals with the problem of modelling the dynamics of knowledge in intelligent systems, that is, how the beliefs of a cognitive agent are modified in some dynamic scenarios. In this paper we present a first approach to credibility-limited multiple belief base revision, that is, a way of non prioritized belief revision where i) epistemic states are represented by belief bases, ii) epistemic inputs are represented by finite sets and iii) the epistemic input is bounded to credible beliefs. This paper tries to advance in constructive methods, postulates and representation theorems for this new kind of revision operators.
