An Efficient Dialogue Control Method under System’s Limited Knowledge

This paper presents a novel method that controls a dialogue
between a spoken dialogue system and a user efficiently so that
the system responds as helpfully as possible within the limits of
its knowledge. Due to speech recognition errors, a system and
user must engage in a "confirmation dialogue" to clarify a user’s
request. Although a confirmation dialogue is unavoidable, it
should be as concise as possible. Previous methods do not
sufficiently allow for the effect of the limits of the system’s
knowledge on the efficiency of dialogue. The result is
unnecessarily long dialogues to confirm a user’s request
minutely even if the request is beyond the system’s knowledge.
This paper describes a method that controls a dialogue
efficiently so as to avoid an unnecessary confirmation dialogue
and presents a computational efficiency criterion for dialogue
control within the limits of the system’s knowledge.
