Abstract
Dialogue systems research is traditionally focused on dialogues between two interlocutors, largely ignoring group conversations. Moreover,
most previous research is focused either on task-oriented dialogue (e.g. restaurant bookings)
or user engagement (chatbots), while research on systems for collaborative dialogues is an under-explored area. To this end, we introduce a dataset containing collaborative conversations on solving a cognitive task, consisting of 226 group dialogues and 6693 utterances. Furthermore, we propose a novel annotation schema that captures deliberation cues and release 50 dialogues annotated with it. Finally, we demonstrate the usefulness of the annotated data in training classifiers to predict the constructiveness of a conversation
