结构化论证中的内在论证强度:一种原则性的方法

Intrinsic Argument Strength in Structured Argumentation: a Principled Approach

Utrecht University(乌得勒支大学)

Jeroen Paul Spaans

摘要:

抽象论证为我们提供了诸如渐进式和Dung语义学等方法,用于在其他论证的潜在攻击之后评估论证。其中一些方法可以将参数的内在强度作为输入,以调节参数之间的攻击效果。这些方法来自抽象论证,只关注论证之间的关系,而不关注论证本身的结构。在结构化论证中,通过从前提开始链接推理规则来构建论证的方式被考虑在内。在本文中,我们研究的方法分配的论点,其内在的力量,根据的前提和推理规则的优势,用于形成说的论点。我们首先定义一组原则,这些原则是强度分配方法可能满足的属性。然后,我们提出了两个这样的方法,并分析它们满足哪些原则。最后,我们提出了一个通用的系统,用于创建新的强度分配方法,并谈到这个系统的属性有关的建议原则。

英文摘要:

Abstract argumentation provides us with methods such as gradual and Dung semantics with which to evaluate arguments after potential attacks by other arguments. Some of these methods can take intrinsic strengths of arguments as input, with which to modulate the effects of attacks between arguments. Coming from abstract argumentation, these methods look only at the relations between arguments and not at the structure of the arguments themselves. In structured argumentation the way an argument is constructed, by chaining inference rules starting from premises, is taken into consideration. In this paper we study methods for assigning an argument its intrinsic strength, based on the strengths of the premises and inference rules used to form said argument. We first define a set of principles, which are properties that strength assigning methods might satisfy. We then propose two such methods and analyse which principles they satisfy. Finally, we present a generalised system for creating novel strength assigning methods and speak to the properties of this system regarding the proposed principles.
