英文摘要：
  With the large-scale penetration of the internet, for the first time, humanity has become linked by a single, open, communications platform. Harnessing this fact, we report insights arising from a unified internet activity and location dataset of an unparalleled scope and accuracy drawn from over a trillion (1.5$\\times 10^{12}$) observations of end-user internet connections, with temporal resolution of just 15min over 2006-2012. We first apply this dataset to the expansion of the internet itself over 1,647 urban agglomerations globally. We find that unique IP per capita counts reach saturation at approximately one IP per three people, and take, on average, 16.1 years to achieve; eclipsing the estimated 100- and 60- year saturation times for steam-power and electrification respectively. Next, we use intra-diurnal internet activity features to up-scale traditional over-night sleep observations, producing the first global estimate of over-night sleep duration in 645 cities over 7 years. We find statistically significant variation between continental, national and regional sleep durations including some evidence of global sleep duration convergence. Finally, we estimate the relationship between internet concentration and economic outcomes in 411 OECD regions and find that the internet\'s expansion is associated with negative or positive productivity gains, depending strongly on sectoral considerations. To our knowledge, our study is the first of its kind to use online/offline activity of the entire internet to infer social science insights, demonstrating the unparalleled potential of the internet as a social data-science platform.

中文摘要：
随着互联网的大规模渗透，人类第一次被一个单一、开放的通信平台联系起来。利用这一事实，我们报告了一个统一的互联网活动和位置数据集所产生的见解，该数据集的范围和准确性无与伦比，来自于对最终用户互联网连接的一万多亿（1.5美元乘以10 ^{12}美元）的观察，在2006-2012年间，时间分辨率仅为15分钟。我们首先将此数据集应用于互联网本身在全球1647个城市群的扩展。我们发现，独特的人均IP数达到饱和，大约每三个人有一个IP，平均需要16.1年才能实现；使蒸汽发电和电气化的估计100年和60年饱和时间相形见绌。接下来，我们使用日间互联网活动特征来放大传统的夜间睡眠观察，得出了7年来645个城市夜间睡眠持续时间的第一个全球估计值。我们发现大陆、国家和地区的睡眠时间之间存在统计上的显著差异，包括一些全球睡眠时间趋同的证据。最后，我们估计了411个经合组织地区互联网集中度与经济成果之间的关系，并发现互联网的扩张与生产率的负增长或正增长相关，这在很大程度上取决于部门因素。据我们所知，我们的研究是首次利用整个互联网的在线/离线活动来推断社会科学见解，展示了互联网作为社会数据科学平台的无与伦比的潜力。

二级分类：Social and Information Networks        社会和信息网络
分类描述：Covers the design, analysis, and modeling of social and information networks, including their applications for on-line information access, communication, and interaction, and their roles as datasets in the exploration of questions in these and other domains, including connections to the social and biological sciences. Analysis and modeling of such networks includes topics in ACM Subject classes F.2, G.2, G.3, H.2, and I.2; applications in computing include topics in H.3, H.4, and H.5; and applications at the interface of computing and other disciplines include topics in J.1--J.7. Papers on computer communication systems and network protocols (e.g. TCP/IP) are generally a closer fit to the Networking and Internet Architecture (cs.NI) category.
涵盖社会和信息网络的设计、分析和建模，包括它们在联机信息访问、通信和交互方面的应用，以及它们作为数据集在这些领域和其他领域的问题探索中的作用，包括与社会和生物科学的联系。这类网络的分析和建模包括ACM学科类F.2、G.2、G.3、H.2和I.2的主题；计算应用包括H.3、H.4和H.5中的主题；计算和其他学科接口的应用程序包括J.1-J.7中的主题。关于计算机通信系统和网络协议（例如TCP/IP）的论文通常更适合网络和因特网体系结构（CS.NI）类别。
