Policy Activation for Open-Ended Dialogue Management
Pierre Lison, Geert-Jan M. Kruijff · 2010
An important difficulty in developing spoken dialogue systems for robots is the open-ended nature of most interactions. Robotic agents must typically operate in complex, continuously changing environments which are difficult to model and do not provide any clear, pre-defined goal. Directly capturing this complexity in a single, large dialogue policy is thus inadequate. This paper presents a new approach which tackles the com-plexity of open-ended interactions by breaking it into a set of small, independent policies, which can be acti-vated and deactivated at runtime by a dedicated mecha-nism. The approach is currently being implemented in a spoken dialogue system for autonomous robots.
