Abstract
We consider the problem where a set of individuals has to classify $m$
objects into $p$ categories by aggregating the individual classifications, and
no category can be left empty. An aggregator satisfies \emph{Expertise} if
individuals are decisive either over the classification of a given object, or
the classification into a given category. We show that requiring an aggregator
to satisfy \emph{Expertise} and be either unanimous or independent leads to
numerous impossibility results.
