On some semantic consequences of turn taking
Implicit in most formal semantic work is the assumption that
in a conversation the participants have equal access to the (semantic) objects
in the context. In this paper I argue against this assumption by pointing out a
puzzle concerning the resolution options in dialogue of fact-operator ellipsis.
I develop an account of the puzzle within a dialogue-games approach by refining
the structure on the common ground facts and explicating the update potential
of utterances.
