Group deliberation enables people to collaborate and solve problems, however, it is understudied due to a lack of resources. To this end, we introduce the first publicly available dataset containing collaborative conversations on solving a well-established cognitive task, consisting of 500 group dialogues and 14k utterances. In 64% of these conversations, the group members are able to find a better solution than they had identified individually, and in 43.8% of the groups who had a correct answer as their final solution, none of the participants had solved the task correctly by themselves. Furthermore, we propose a novel annotation schema that captures deliberation cues and release all 14k utterances annotated with it. Finally, we use the proposed dataset to develop and evaluate two methods for generating deliberation utterances. The data collection platform, dataset and annotated corpus are publicly available at https://delibot.xyz.

翻译：群体商议使人们能够协作解决问题，然而缺乏相关资源导致这一领域研究不足。为此，我们推出了首个公开可用的数据集，包含针对经典认知任务进行协作对话的数据，涵盖500组群体对话及1.4万条话语。其中64%的对话中，群体成员能够找到比个人独立时更优的解决方案；在最终答案正确的群体中，43.8%的群体成员此前均未独立解决该任务。此外，我们提出了一种新颖的标注方案以捕捉商议线索，并发布经此标注的全部1.4万条话语。最后，我们利用该数据集开发并评估了两种生成商议话语的方法。数据收集平台、数据集及标注语料库可通过 https://delibot.xyz 公开获取。
