Toward a Characterization of Uncertainty Measure for the Dempster-Shafer
  Theory
  This is a working paper summarizing results of an ongoing research project
whose aim is to uniquely characterize the uncertainty measure for the
Dempster-Shafer Theory. A set of intuitive axiomatic requirements is presented,
some of their implications are shown, and the proof is given of the minimality
of recently proposed measure AU among all measures satisfying the proposed
requirements.
