Philippe Muller & Laurent Prévot:
Grounding information in route explanation
dialogues
Abstract
This paper studies the role of several factors influencing the grounding
of information in a French corpus of direction-giving dialogues. We focussed
on how speakers agree on specific locations that are part of an explanation.
Spatial knowledge is thus seen here as a means of a precise semantic analysis
of the meaning of a certain type of dialog act (feedback responses). We show
here how the different kinds of feedbacks that can be accounted for by our
data, looking at the type of lexical cues in utterances, the type of dialog
act targetted by the feedback and the span of the conversation that falls
under the scope of such a feedback. We then propose an interpretation of
this as different mechanisms for speakers' agreement.
