The Patterns
We deal with situations where argumentation frameworks are not generated from a knowledge base, but where the knowledge engineer has to directly design the arguments and attacks. In many cases, for the engineer is easier to reuse parts of existing frameworks, so a methodology for representing abstractions facilitating such reuse and for defining their meaning is needed.
Argumentation patterns are visual descriptions for how to solve design problems of argumentation frameworks, that can be used in many situations. Argumentation patterns are sets of arguments related to each other in such a way that they cannot be expressed directly with the basic attack relation.
The higher-order attack pattern, and its behaviour when attacks from external arguments are present.
The conjunctive and disjunctive pattern, and their behaviour when attacks from external arguments are present.
The proof standard pattern.
