Constraints associated with Choquet integrals and other aggregation-free ranking devices

Souhila Kaci, Henri Prade.

The paper contrasts Choquet
integral-based aggregation method
with a rank-ordering approach based
on the specification of constraints
induced by generic principles (or by
examples of ranking of particular
vectors of attribute values). The
latter approach does not use any
aggregation operation for evaluating
the vectors. It is based on the
minimal specificity principle (which
amounts to demote vectors as much
as they violate constraints) in order
to get a complete preorder on the
vectors. This approach is compared
on an illustrative example to a
Choquet integral-based method.
We point out the specificity of
constraints expressing relative
importance that underly Choquet
integral.
