Godel Fuzzy Argumentation Frameworks

Godel Fuzzy Argumentation Frameworks
Godel Fuzzy Argumentation Frameworks
In this paper we combine fuzzy set theory and argumentation to facilitate the use of fuzzy arguments and attacks. Unlike many existing approaches, our work does not require the use of any parameters, bringing it closer to Dung’s work in spirit. We begin by introducing Fuzzy Argumentation Frameworks, and specialise them using the Godel t-norm. We then examine this framework’s properties and show that the standard Dung extensions are obtained, though the stable semantics coincide with the preferred. Finally, we examine the relationship between our framework and Dung’s original system, as well as the existing fuzzy frameworks, describing where they overlap and differ.

Abstract

In this paper we combine fuzzy set theory and argumentation to facilitate the use of fuzzy arguments and attacks. Unlike many existing approaches, our work does not require the use of any parameters, bringing it closer to Dung’s work in spirit. We begin by introducing Fuzzy Argumentation Frameworks, and specialise them using the Godel t-norm. We then examine this framework’s properties and show that the standard Dung extensions are obtained, though the stable semantics coincide with the preferred. Finally, we examine the relationship between our framework and Dung’s original system, as well as the existing fuzzy frameworks, describing where they overlap and differ.
