This volume covers key topics in the field from a variety of leading researchers. In one volume, readers gain exposure to several perspectives in the areas of corpus annotation and analysis, dialogue system construction, theoretical perspectives on communicative intention, context-based generation, and modeling of discourse structure. Based on the 2nd SIGdial workshop on Discourse and Dialogue held in conjunction with Eurospeech 2001, it is of interest to researchers and practitioners in dialogue and discourse processing.
