论证是人工智能和多智能体系统中的一种重要方法，它为单个智能体做出理性决策、为多个智能体达成协议提供基础，也是支持广泛智能体交互的一种机制。在这样的工作中，攻击的概念在论点之间发挥了至关重要的作用，攻击的概念得到了很好的研究。例如，有一系列不同的方法来确定一组论点中的哪一种应该被接受，因为它们之间存在攻击。较少研究的是论据之间的支持的概念，然而，一个论据可能支持另一个论据的想法是非常直观的，在决策选择可能有多个赞成和反对的论据的决策领域似乎特别相关。在过去的十年里，对论证中的支持的研究重新引起了研究者的注意，但大多数方法都是在抽象论证的背景下研究支持，而忽略了构成论点的要素。相反，本文在结构化论证系统的背景下研究了论点之间的支持的概念，在结构化论证系统中，构成论点的要素起着至关重要的作用。提出了不同的支持形式，每种支持形式都考虑了论点的结构；并研究了这些支持形式之间的关系。然后，本文考察了支持的结构化形式和抽象形式之间是否存在对应关系，并确定抽象形式是否可以用具体的支持形式在结构化论元方面进行实例化。结论是，结构化论证中的支持与抽象论证中的支持并不能很好地契合，这表明需要更多的工作来开发抽象论证中的支持形式，以模拟结构化论证中发生的事情。
Argumentation is an important approach in artificial intelligence and multiagent systems, providing a basis for single agents to make rational decisions, and for groups of agents to reach agreements, as well as a mechanism to underpin a wide range of agent interactions. In such work, a crucial role is played by the notion ofattackbetween arguments, and the notion of attack is well-studied. There is, for example, a range of different approaches to identifying which of a set of arguments should be accepted given the attacks between them. Less well studied is the notion ofsupportbetween arguments, yet the idea that one argument may support another is very intuitive and seems particularly relevant in the area of decision-making where decision options may have multiple arguments for and against them. In the last decade, the study of support in argumentation has regained attention among researchers, but most approaches address support in the context of abstract argumentation where the elements from which arguments are composed are ignored. In contrast, this paper studies the notion of support between arguments in the context of structured argumentation systems where the elements from which arguments are composed play a crucial role. Different forms of support are presented, each of which takes into account the structure of arguments; and the relationships between these forms of support are studied. Then, the paper investigates whether there is a correspondence between the structured and abstract forms of support, and determines whether the abstract formalisms may be instantiated using concrete forms of support in terms of structured arguments. The conclusion is that support in structured argumentation does not mesh well with support in abstract argumentation, and this suggests that more work is required to develop forms of support in abstract argumentation that model what happens in structured argumentation.
