Referring under Restricted Interactivity Conditions
Raquel Fernández, Tatjana Lucht, David Schlangen · 2007
We report results on how the collaborative process of referring in task-oriented dialogue is affected by the restrictive interactivity of a turn-taking policy commonly used in dialogue systems, namely push-to-talk.Our findings show that the restriction did not have a negative effect.Instead, the stricter control imposed at the interaction level favoured longer, more effective referring expressions, and induced a stricter and more structured performance at the level of the task.
