Generalized abstract argumentation: Handling arguments in FOL fragments

Abstract

Generalized argumentation frameworks relate formulae in classical logic to arguments based on the Dung's classic framework. The main purpose of the generalization is to provide a theory capable of reasoning (following argumentation technics) about inconsistent knowledge bases (KB) expressed in FOL fragments. Consequently, the notion of argument is related to a single formula in the KB. This allows to share the same primitive elements from both, the framework (arguments) and, the KB (formulae). A framework with such features would not only allow to manage a wide range of knowledge representation languages, but also to cope with the dynamics of knowledge in a straightforward manner. © 2009 Springer Berlin Heidelberg.
