  The paper addresses the problem of representing ambiguities in a way that
allows for monotonic disambiguation and for direct deductive computation. The
paper focuses on an extension of the formalism of underspecified DRSs to
ambiguities introduced by plural NPs. It deals with the collective/distributive
distinction, and also with generic and cumulative readings. In addition it
provides a systematic account for an underspecified treatment of plural pronoun
resolution.
