Specificity and Context Dependent Preferences in Argumentation Systems.

Dung and Son [6] argue that specificity as a criterion for resolving conflicts between arguments, is context dependent. They propose to use arguments to address the context dependency of specificity in combination with a new special argumentation semantics. Unfortunately, their solution is restricted to argumentation systems without undercutting arguments. This paper presents a more general solution which allows for undercutting arguments and allows for any argumentation semantics. Moreover, the solution is applicable to any form a context dependent preferences.
