Abstract
The paper focuses on an Information State (IS) based dialogue manager developed for Carl, an intelligent mobile robot. It uses a Knowledge Acquisition and Management (KAM) module that integrates information obtained from various interlocutors. This mixed-initiative dialogue manager (DM) handles pronoun resolution, is capable of performing different kinds of clarification/confirmation questions and generates observations based on the current knowledge acquired. An evaluation of the DM on knowledge acquisition tasks is shown.
