A dialogue example
A dialogue from the user test of the Danish Dialogue System (translated from the Danish [Bernsen et al. 1998b]). The user interacts with the system for the first time. Turn numbers refer to the transcription of the dialogue with subject (or user) number 13 [Dybkjær et al. 1996m]. For ease of reference the turns are sub-divided into utterance units. For instance, “S1” is the first system turn which consists of two utterance units (S1a) and (S1b), and the user’s answer is turn “U1” which consists of one utterance unit (U1a).
