Section Title:
introduction

Context before the citation:
Both kinds of annotation were carried out using ANVIL (Kipp, 2004). For this study, we added semantic labels â including dialogue acts â and gesture annotation. In the subset of the corpus considered here, 82% of the feedback expressions bear stress or tone information, and 12% are unstressed; 7% of them are marked with onset or offset hesitation, or both.

Citation Sentence:

Context after the citation:
To distinguish among the various functions that feedback expressions have in the dialogues, we selected a subset of the categories defined in the emerging ISO 24617-2 standard for semantic annotation of language resources. This subset comprises the categories Accept, Decline, RepeatRephrase and Answer. Moreover, all feedback expressions were annotated with an agreement feature (Agree, NonAgree) where relevant. Finally, the two turn management categories TurnTake and TurnElicit were also coded.
