Preface
This book describes the development and evaluation of a novel type of spoken language dialogue system that proactively interacts in the conversation with two users. Spoken language dialogue systems are increasingly deployed in more and more application domains and environments. As a consequence, the demands posed on the systems are rising rapidly. In the near future, a dialogue system will be expected, for instance, to be able to perceive its environment and users and adapt accordingly. It should recognise the users’ goals and desires and react in a proactive and flexible way. Flexibility is also required in the number of users that take part in the interaction. An advanced dialogue system that meets these requirements is presented in this work. A specific focus has been placed on the dialogue management of the system on which the multi-party environment poses new challenges. In addition to the human-computer interaction, the human-human interaction has to be considered for dialogue modelling. A prevalent approach to dialogue management has been adapted accordingly. To enable proactive interaction a detailed dialogue history has been implemented. As opposed to common dialogue systems which start from scratch when the interaction begins, the system developed in the scope of this book starts modelling as soon as the conversation enters its specified domain. The knowledge acquired during this early stage of the conversation enables the system to take the initiative for m
