Efficient Computation of Argumentation Semantics

Chapter 5

Relations between Global Semantics and Local Semantics

Abstract

Based on the notion of sub-frameworks and their semantics, in this chapter, we introduce the relations between the semantics of an argumentation framework and those of its sub-framework, which lays a foundation for the establishment of some efficient approaches for computing the semantics of argumentation.

5.1 Introduction

In Chapters 2 and 4, we introduce the semantics of an argumentation framework and that of its sub-frameworks (called the global semantics and the local semantics of the argumentation framework, respectively). Now, an important question arises: ...
