A Note on Prototype Revision
Renata Wassermann, Eduardo Fermé

Abstract:
Belief revision deals with the problem of how to accommodate new assertions 
into an existent body of knowledge.  Traditionally, the body of knowledge is 
represented by a belief set, a set of  formulas closed under logical 
implication. A belief set can also be represented by the set of possible 
worlds where all its formulas hold.
The idea of this paper is to apply methods developed in the context of belief
revision in order to accommodate new information about concepts.
