Side Effect Free Dialogue Management in a Voice Enabled Procedure Browser

摘要

We describe a general side-effect free dialogue management architecture suitable for command and control tasks, which extends the "update semantics" framework by including task as well as dialogue information in the information state. We show that this enables simple and elegant treatments of several dialogue management problems, including corrections, confirmations, querying of the environment, and regression testing. The architecture is discussed in the context of an implemented application, a voice enabled procedure browser for an astronautics domain.
