Argumentation as a General Framework for Uncertain Reasoning
  Argumentation is the process of constructing arguments about propositions,
and the assignment of statements of confidence to those propositions based on
the nature and relative strength of their supporting arguments. The process is
modelled as a labelled deductive system, in which propositions are doubly
labelled with the grounds on which they are based and a representation of the
confidence attached to the argument. Argument construction is captured by a
generalized argument consequence relation based on the ^,--fragment of minimal
logic. Arguments can be aggregated by a variety of numeric and symbolic
flattening functions. This approach appears to shed light on the common logical
structure of a variety of quantitative, qualitative and defeasible uncertainty
calculi.
