Continuing a series of successful workshops in Hong Kong, Aalborg, Philadelphia, Sapporo and Boston, this workshop spans the ACL and ISCA SIGdial interest area of discourse and dialogue. The workshop series provides a regular forum for the presentation of research in the discourse and dialogue area to both the larger SIGdial community as well as to researchers outside this community. The workshop is organised by SIGdial, which is sponsored jointly by ACL and ISCA.
