Meta-level Argumentation with Argument Schemes

Firewall configuration: An application of multiagent metalevel argumentation

“…This is close to the approach adopted by [34], though the latter paper captures critical questions though the use of undercutting [39] rules, which (in our example) would deny the applicability of the transitivity rule rather than (as we do) ensuring that the argument generated using the rule is defeated. Of course, undercutting attacks are implicitly a metalevel notion.…”

“…As already mentioned, metalevel argumentation was formally introduced in [32], and the idea of metalevel argumentation has been used [31] to provide an abstract integration of accrual and dialectical argumentation and to integrate argumentation-based reasoning about preferences with the object level arguments. [44] presented an argumentation-based model of social interaction integrating both object-level and metalevel argumentation, and, as already mentioned, [34] integrated structured argumentation and metalevel argumentation to express argumentation schemes. Both these latter papers are a close fit with what we discuss here, though neither addresses our firewall domain.…”

Meta-Argumentation Frameworks for Multi-party Dialogues

“…This paper presents an approach for reasoning about trust in dialogues that combines three of the most popular mechanisms used within computational modelling of argumentation: ASPIC+ [10], argument schemes [12] and meta-argumentation [7,11].…”

“…We map arguments and attacks in our hierarchical system to arguments and defeats in a bimodal argument graph [7] by stating that argument a defeats argument b iff a attacks b and there are some meta-arguments α, β such that α supports a and β supports b and α attacks β. Properties of the argument framework at the object level is encoded using a fragment of ASPIC+.…”

“…Since we consider the arguments advanced during the dialogue, as well as argument about those arguments, our approach builds on Muller's meta-argumentation system [7]. Here, object-level arguments are advanced which deal with the topic of the dialogue.…”
