Abstract
We explore the use of restricted dialogue
contexts in reinforcement learning (RL)
of effective dialogue strategies for infor-
mation seeking spoken dialogue systems
(e.g. COMMUNICATOR (Walker ... start of a
dialogue) .
Finally, let us note that the performance of the
RL strategies is close to optimal, but that there is
some room for improvement. With respect to the
HLG05 metric, the optimal...
