This book edition highlights recent trends and important issues that still remain only partially solved or even unsolved within the broad ?eld of discourse and dialogue. The ?eld is discussed and illustrated both from an overall spoken (multimodal) dialogue system perspective as well as from a more compone- related perspective. Issues discussed include, for example, discourse and dialogue modelling in research versus industrial spoken dialogue systems, evaluation, miscommunication and error handling, grounding, statistical and corpus-based approaches to discourse and dialogue modelling, data analysis, and corpus annotation and annotation tools. We believe that jointly this collection of chapters provides a good picture of how far we are today within discourse and dialogue and of important ch- lenges ahead. On this background we hope that computer scientists, engineers, and others who work in the broad area of discourse and dialogue, no matter if from an academic or industrial perspective, may bene?t from the book and ?nd it useful to their own work. Graduate students and Ph.D. students focusing on topics in discourse and dialogue may also ?nd the book interesting and pro?t from reading it. This book edition is based on a selected subset of papers from the successful 6th SIGdial Workshop on Discourse and Dialogue held in Lisbon, Portugal, in September 2005 in conjunction with the 9th Eurospeech (Interspeech) conf- ence. SIGdial is a special interest group on discourse and dialogue sponsored jointly by the two parent organisations ACL (Association for Computational Linguistics) and ISCA (International Speech Communication Association).
This book is a collection of eleven chapters which together represent an original contribution to the field of (multimodal) spoken dialogue systems. The chapters include highly relevant topics, such as dialogue modeling in research systems versus industrial systems, evaluation, miscommunication and error handling, grounding, statistical and corpus-based approaches to discourse and dialogue modeling, data analysis, and corpus annotation and annotation tools. The book contains several detailed application studies, including, e.g., speech-controlled MP3 players in a car environment, negotiation training with a virtual human in a military context, application of spoken dialogue to question-answering systems, and cognitive aspects in tutoring systems. The chapters vary considerably with respect to the level of expertise required in advance to benefit from them. However, most chapters start with a state-of-the-art description from which all readers from the spoken dialogue community may benefit. Overview chapters and state-of-the-art descriptions may also be of interest to people from the human-computer interaction community.
