Exploring Attention in a Multimodal Corpus of Guided Tours

This paper explores the possibility to annotate engagement as an extra-linguistic information in a multimodal corpus of guided tours in cultural sites. Engagement has been annotated in terms of gain or loss of perceived attention from the audience, and this information has been aligned to the transcription of the speech from the guide. A preliminary analysis suggests that the level of engagement cor-relates with some specific linguistic features, opening up to possible future exploitation.
