Abstract. This paper presents an approach to modelling and reasoning about ar-
guments that exploits and combines two of the most popular mechanisms used
within computational modelling of argumentation: argumentation schemes and
abstract argumentation frameworks. Our proposal combines the desirable prop-
erties of each by representing the components of argumentation schemes as ar-
gumentation frameworks. This allows us to make use of the structure provided
by the schemes to guide dialogues and provide contextual elements of evalua-
tion, whilst retaining the desirable properties of abstract frameworks to enable
evaluation with respect to the logical relations between arguments. Our proposal
takes account of dialogical aspects within a debate, such as burden of proof, and
we illustrate our approach through a particular argumentation scheme, namely
argument from expert opinion.
