Daisie: Information State Dialogues for Situated Systems

In this paper, we report on an information-state update (ISU) based dialogue management framework developed specifically for the class of situated systems. Advantages and limitations of the underlying ISU methodology and its supporting tools are first discussed, followed by an overview of the situated dialogue framework. Notable features of the new framework include its ISU basis, an assumption of agency in domain applications, a tightly-coupled, plugin-based integration mechanism, and a function-based contextualization process. In addition to reporting on these features, we also compare the framework to existing works both inside and outside of the situated dialogue domain.
