Proceedings of the 9th SIGdial Workshop on Discourse and Dialogue

We are pleased to present in this volume, the Proceedings of the 9th SIGdial Workshop on Discourse and Dialogue. These proceedings could not have been produced without the assistance of this year's excellent program committee. The quality of the collection is a result of their efforts and we are indebted to them for donating their time and expertise. 19 of the 46 submissions were accepted as long papers and another 10 were accepted as short papers. This selection of papers follows the SIGdial tradition of providing a venue for work on theory, implemented systems, developed work and new approaches. The topics covered include generation for dialogue systems, dialogue system evaluation, opinions, persuasion, multi-party dialogue, probabilistic methods for dialogue, grounding and the use of dialogue features for improving speech processing. We are optimistic that the breadth and quality of the selected papers will contribute to a lively and interesting workshop event and will prove a valuable resource for the SIGdial readership.
