We discuss explanations for formal (abstract and structured) argumentation—the question of whether and why a certain argument or claim can be accepted (or not) under various extension-based semantics. We introduce a flexible framework, which can act as the basis for many different types of explanations. For example, we can have simple or comprehensive explanations in terms of arguments for or against a claim, arguments that (indirectly) defend a claim, the evidence (knowledge base) that supports or is incompatible with a claim, and so on. We show how different types of explanations can be captured in our basic framework, discuss a real-life application and formally compare our framework to existing work.

论证解释的基本框架


我们讨论对形式（抽象和结构化）论证的解释——在各种基于扩展的语义下是否以及为什么某个论证或主张可以被接受（或不能）的问题。我们引入了一个灵活的框架，它可以作为许多不同类型解释的基础。例如，我们可以根据支持或反对某个主张的论据、（间接）捍卫某个主张的论据、支持或与某个主张不相容的证据（知识基础）等来进行简单或全面的解释。我们展示了如何在我们的基本框架中捕获不同类型的解释，讨论现实生活中的应用程序，并将我们的框架与现有工作进行正式比较。
