NIEVES, Juan Carlos; OSORIO, Mauricio  e  CORTES, Ulises. An Overview of Argumentation Semantics. Comp. y Sist. [online]. 2008, vol.12, n.1, pp. 65-88. ISSN 1405-5546.

The main purpose of argumentation theory is to study the fundamental mechanisms that humans use in argumentation, and to explore ways to implement these mechanisms on computers. During the last years, argumentation has been gaining increasing importance in Computer Science, especially in areas as Artificial Intelligence, e-commerce, Multi-agent Systems and Decision-Making. In this paper, we present a brief overview of abstract argumentation semantics. In order to promote and disseminate this young area, we describe the fundamental role of argumentation in a medical application. Moreover, we present some results in order to close the huge gap between argumentation theory and argumentation systems. We will see that these results also suggest a general method for exploring some challenges in argumentation theory.
