在本文中，我们阐述了危机中的大型公共调查采用众包方式时出现的道德困境。我们重点关注波士顿马拉松爆炸事件发生后两个在线团体的行为的公众舆论变化。这些团体收集和组织对受害者的救济，收集爆炸现场的照片和视频，并创建在线机制来共享和分析在线收集的图像。他们还利用大量的数据和互联网的可供性来回答“谁是肇事者，使用了哪种炸弹？”这个问题。我们通过公众舆论、Twitter 样本并对这些数据进行情绪分析来观察他们的行为。我们使用这个工具来确定危机调查期间公众对在线公众的行为变得更加积极或消极的时刻。我们用它作为社会认可或反对他们行为的替代品或代理，这暴露了在线公众跨越道德界限时公众情绪的大幅波动。
In this paper we illustrate the ethical dilemmas that arise when large public investigations in a crisis are crowdsourced. We focus the variations in public opinion concerning the actions of two online groups during the immediate aftermath of the Boston Marathon Bombing. These groups collected and organized relief for victims, collected photos and videos taken of the bombing scene and created online mechanisms for the sharing and analysis of images collected online. They also used their large numbers and the affordances of the Internet to produce an answer to the question, "who was the perpetrator, and what kind of bomb was used?" We view their actions through public opinion, through sampling Twitter and applying a sentiment analysis to this data. We use this tool to pinpoint moments during the crisis investigation when the public became either more positively or negatively inclined toward the actions of the online publics. We use this as a surrogate, or proxy, for social approval or disapproval of their actions, which exposes large swings in public emotion as ethical lines are crossed by online publics.
