On Structured Belief Bases ­ Preliminary Report
Renata Wassermann

In this paper some ideas for adding structure to belief bases are
presented. Structured belief bases can be seen as graphs, where each
node is a belief and two nodes are adjacent if and only if they are
related. Some notions of relatedness are defined. We then show how
this extra structure can be used for implementing local change as
defined in [HW98].
