Cascaded Dialogue Modelling for Situated Human-Robot Interactions

The paper discusses new requirements for dialogue modelling that situated human-robot interactions and increasingly demanding smart contexts impose on dialogue systems. Based on Constructive Dialogue Modelling, the paper describes human communication enablements (contact, perception, understanding and reaction) and their modelling as a hierarchy which supports the agent to produce appropriate dialogue behaviour. The hierarchy is compared to the subsumption architecture for mobile robots, and a cascaded model with multiple parallel yet hierarchical dialogue processing tasks is proposed as a model for context-aware dialogue management.
