Comments - from Jean CarlettaI think there are two areas of overlap between my interests and the work in AIAI in this area: 1. the possible development of a better tool for the design of spoken dialogue systems which draws on standards in representing plans and processes (for the tool I described, see http://cslu.cse.ogi.edu/toolkit/) ; and 2. work on business process modelling which integrates our understanding of the properties of group communication (see http://www.cogsci.ed.ac.uk/~jeanc/publications.html, papers in Psychological Science, Small Group Research, and Ergonomics).
