Choice revision is a sort of non-prioritized multiple revision, in which the agent partially accepts the new information represented by a set of sentences. We investigate the construction of choice revision based on a new approach to belief change called descriptor revision. We prove that each of two variants of choice revision based on such construction is axiomatically characterized with a set of plausible postulates, assuming that the object language is finite. Furthermore, we introduce an alternative modelling for choice revision, which is based on a type of relation on sets of sentences, named multiple believability relation. We show without assuming a finite language that choice revision constructed from such relations is axiomatically characterized with the same sets of postulates that we proposed for the choice revision based on descriptor revision, whenever the relations satisfy certain rationality conditions.

选择修改

选择修订是一种无优先级的多重修订，其中代理部分接受由一组句子表示的新信息。我们基于一种称为描述符修订的信念变化新方法研究了选择修订的构建。我们证明，假设对象语言是有限的，基于这种构造的选择修订的两个变体中的每一个都公理地具有一组合理的假设。此外，我们引入了一种用于选择修订的替代模型，该模型基于句子集上的一种关系类型，称为多重可信度关系。
