近年来，抗议浪潮席卷各国和各大洲，在某些情况下导致政治和政府变革。许多媒体的注意力都集中在越来越多地使用社交媒体来协调和提供关于这些抗议活动的即时报道上。在这里，我们调查是否有可能通过定量分析照片共享网站Flickr上的活动来识别抗议爆发。我们分析了244个国家和地区在2013年上传到Flickr的2500万张照片，并确定了每个国家和地区每周有多少照片用34种不同的语言标记了“抗议”一词。我们发现，特定国家和地区一周内带有“抗议”标签的照片比例越高，《卫报》上有关该国家和地区以及该周抗议活动的报道数量就越多。我们的研究结果强调了上传到互联网上的照片作为全球、廉价和快速获得的真实的世界人类行为测量数据的来源的潜在价值。
Recent years have witnessed waves of protests sweeping across countries and continents, in some cases resulting in political and governmental change. Much media attention has been focused on the increasing usage of social media to coordinate and provide instantly available reports on these protests. Here, we investigate whether it is possible to identify protest outbreaks through quantitative analysis of activity on the photo sharing site Flickr. We analyse 25 million photos uploaded to Flickr in 2013 across 244 countries and regions, and determine for each week in each country and region what proportion of the photographs are tagged with the word “protest” in 34 different languages. We find that higher proportions of “protest”-tagged photographs in a given country and region in a given week correspond to greater numbers of reports of protests in that country and region and week in the newspaper The Guardian. Our findings underline the potential value of photographs uploaded to the Internet as a source of global, cheap and rapidly available measurements of human behaviour in the real world.
