A novel approach to measuring uncertainty and uncertainty-based inform
ation in Dempster-Shafer theory is proposed (independently also propos
ed by Maeda et al. [1993]). It is shown that the proposed measure of t
otal uncertainty in Dempster-Shafer theory is both additive and subadd
itive, has a desired range, and collapses correctly to either the Shan
non entropy or the Hartley measure of uncertainty for special probabil
ity assignment functions. The paper is restricted, for the sake of sim
plicity, to finite sets.
