On the links between argumentation-based reasoning and nonmonotonic
  reasoning
  In this paper we investigate the links between instantiated argumentation
systems and the axioms for non-monotonic reasoning described in [9] with the
aim of characterising the nature of argument based reasoning. In doing so, we
consider two possible interpretations of the consequence relation, and describe
which axioms are met by ASPIC+ under each of these interpretations. We then
consider the links between these axioms and the rationality postulates. Our
results indicate that argument based reasoning as characterised by ASPIC+ is -
according to the axioms of [9] - non-cumulative and non-monotonic, and
therefore weaker than the weakest non-monotonic reasoning systems they
considered possible. This weakness underpins ASPIC+'s success in modelling
other reasoning systems, and we conclude by considering the relationship
between ASPIC+ and other weak logical systems.
