连贯设置中的缺省逻辑

Default Logic in a Coherent Setting

Giulianella Coletti, Romano Scozzafava, Barbara Vantaggi

摘要:

在这次演讲中-基于即将发表的论文(Coletti,Scozzafava和Vobrugi 2002)的结果,也是由我们中的一个在“非经典逻辑,近似推理和软计算”会议(Anacapri,意大利,2001)上提出的-我们讨论了通过一个合适的一致的条件概率来表示默认规则的问题,定义在一个条件事件家族上。(在我们的方法中)一个事件被一个命题挑选出来,命题是一个可以是真或假的陈述;一个条件事件因此被两个命题定义,是一个3值实体,第三个值是(在这种情况下)一个条件概率。

英文摘要:

In this talk - based on the results of a forthcoming paper (Coletti, Scozzafava and Vantaggi 2002), presented also by one of us at the Conference on "Non Classical Logic, Approximate Reasoning and Soft-Computing" (Anacapri, Italy, 2001) - we discuss the problem of representing default rules by means of a suitable coherent conditional probability, defined on a family of conditional events. An event is singled-out (in our approach) by a proposition, that is a statement that can be either true or false; a conditional event is consequently defined by means of two propositions and is a 3-valued entity, the third value being (in this context) a conditional probability.
