论文摘要
执法部门的社交媒体监控变得司空见惯，但是对它的软件包的了解知之甚少。通过公共记录请求，我们从Corvallis（俄勒冈州）警察局使用了名为DigitalStakeOut的社交媒体监控软件中获得了日志文件。这些日志文件包括数字策略的专有搜索结果，这些结果已在13个月内运行，其中包括7240个社交媒体帖子。在本文中，我们专注于登录此数据的推文，并考虑由Digital StakeSkout标记的用户的种族和种族身份（通过手动编码）。与该地区的Twitter用户的人口统计相比，我们观察到用户的人口统计数据的差异，但是，我们的样本量太小，无法确定重要性。此外，该地区的Twitter用户的人口统计似乎并没有反映该地区居民的人口统计学，而黑人和西班牙裔人士显然具有更高的代表。我们还重建了与数字策略为Corvallis警察局设置的麻醉品报告有关的关键字，并发现这些关键字标志着与麻醉品或标志性的标志推文或与大麻相关的FLAG Tweet无关的标志推文，这是一种与大麻相关的药物，该药物是在俄勒冈州进行休闲使用的合法使用的药物。几乎所有关键字都具有与麻醉品无关的共同含义（例如\ \ \ obraking，snow，hop，high），这些含义质疑了这种基于关键字的搜索可能必须执行执法的实用程序。
Social media monitoring by law enforcement is becoming commonplace, but little is known about what software packages for it do. Through public records requests, we obtained log files from the Corvallis (Oregon) Police Department's use of social media monitoring software called DigitalStakeout. These log files include the results of proprietary searches by DigitalStakeout that were running over a period of 13 months and include 7240 social media posts. In this paper, we focus on the Tweets logged in this data and consider the racial and ethnic identity (through manual coding) of the users that are therein flagged by DigitalStakeout. We observe differences in the demographics of the users whose Tweets are flagged by DigitalStakeout compared to the demographics of the Twitter users in the region, however, our sample size is too small to determine significance. Further, the demographics of the Twitter users in the region do not seem to reflect that of the residents of the region, with an apparent higher representation of Black and Hispanic people. We also reconstruct the keywords related to a Narcotics report set up by DigitalStakeout for the Corvallis Police Department and find that these keywords flag Tweets unrelated to narcotics or flag Tweets related to marijuana, a drug that is legal for recreational use in Oregon. Almost all of the keywords have a common meaning unrelated to narcotics (e.g.\ broken, snow, hop, high) that call into question the utility that such a keyword based search could have to law enforcement.
