众包用于吸引工人作为各种应用程序的资源，包括灾难响应。但是，诸如图像标签之类的简单任务通常会感到单调并导致工人脱离接触。这为设计成功的众包系统提供了挑战。现有的工作设计研究表明，任务品种是工人动机的关键因素。因此，我们要求亚马逊机械土耳其人的工人完成一系列与灾难响应有关的子任务，这些子任务包括图像标签或地图上的照片区域。我们改变了工人遇到不同子任务类型的频率，并发现以不同频率切换子任务类型会影响工人参与度的措施。这表明子任务中有一定数量的种类比统一的子任务类型更好地吸引众包工人。
Crowdsourcing is used to enlist workers as a resource for a variety of applications, including disaster response. However, simple tasks such as image labeling often feel monotonous and lead to worker disengagement. This provides a challenge for designing successful crowdsourcing systems. Existing research in the design of work indicates that task variety is a key factor in worker motivation. Therefore, we asked Amazon Mechanical Turk workers to complete a series of disaster response related subtasks, consisting of either image labeling or locating photographed areas on a map. We varied the frequency at which workers encountered the different subtask types, and found that switching subtask type at different frequencies impacted measures of worker engagement. This indicates that a certain amount of variety in subtasks may engage crowdsourcing workers better than uniform subtask types.
