....of minimal change is taken into account during the revision of the situation: the parts of S that are consistent with d are maintained in S 0 while the inconsistent ones are modified minimally in order to keep consistence. F. P. Ramsey proposed a method for evaluating a conditional proposition [17]. Ramsey s method was later formulated within the Theory of Epistemic Change [9] That formulation clearly states the close relation between the evaluation of conditionals and a belief change process. In this work we discuss the adequacy to IR of the implementation of the relevance test with ....

....are conditional statements of the form if p were true, q would hold , where p is assumed to be false in the current state of affairs. They are also called conditionals for short. Along this work we will use both names interchangeably. Ramsey anticipated a test for evaluating conditionals [17] that was summarized by Grdenfors as follows [9] in order to find out whether a conditional proposition is acceptable in a given state of belief, one first adds the antecedent of the conditional to the given stock of beliefs. Second, if the antecedent together with the former stocks of beliefs ....

....by y. The selection mechanisms are by nature so corpus specific that in general the original mechanism oe is inappropriate for the new belief set (K; oe; x) This problem is called the problem of iterated belief change. Belief change is closely related to the logic of conditionals. Frank Ramsey [19] suggested that in evaluating a conditional of the form if p (is were true) then q (is would be true) an agent should first make the minimal change in her body of beliefs so that p is accepted, and then check whether q is accepted in this new body of beliefs. If q is indeed accepted in this ....

....jumps. This fact may be explained by ascribing to the agent a conditional belief kangaroo skippy jumps skippy. Note the subjunctive nature of the conditional . This way of determining which conditionals are accepted by an agent in a given belief state is originally due to Frank Ramsey [11]. In some cases of belief change, belief in such conditionals will be carried over to the next belief state, whereas, in others, the evidence will nullify such conditional beliefs. It is only by learning what conditional beliefs are carried over to the new belief state from the old, and what ....

....In the example above, minimal change could mean that we give up either the fact Tweety is a bird , or the rule All birds can fly , but not both. The notion of minimal change also plays a role in defining the meaning of counterfactual implications. This is explicitly expressed in the Ramsey Rule [31]. The Ramsey Rule is summarized by Gardenfors [15] as follows: Accept a proposition of the form if A, then B in a state of belief [or knowledge ] K, if and only if the minimal change of K needed to accept A, also requires accepting B. Gardenfors [13, 15] has shown that with certain assumptions ....
