While there is great interest and activity in building spoken dialogue
systems today, most applications involved very limited domains that
require no significant reasoning. Our goal is to design and build
systems that approach human performance in conversational interaction
in demains that require significant reasoning. We limit our study to
`practical dialogues': dialogues in which the conversants are
cooperatively pursuing specific goals or tasks. These include planning
(e.g., designing a kitchen), information retrieval (e.g., finding out
the weather in New York), customer service (e.g., booking an airline
flight), advice-giving (e.g., helping assemble some modular furniture)
or crisis management (e.g., a 911 center assistant). In fact, our
belief is that the class of practical dialogues includes most anything
about which people might want to interact with a computer.
While each of these different genres of tasks require significantly
different reasoning components and have different structures, we
believe that we can develop an overall model of practical dialogue
that enables us to build domain-independent systems that can
relatively easily be adapted to different domains. The key is
developing an abstract model of collaborative problem solving and
interaction. I will describe our work so far and illustrate with
examples from some systems we have built over the past five years.
