The Copenhagen Networks Study interaction data

The data represents the multi-layer temporal network which connects a population of more than 700 university students over a period of four weeks. The dataset was collected via smartphones as part of the Copenhagen Networks Study. We include the network of physical proximity among the participants (estimated via Bluetooth signal strength), the network of phone calls (start time, duration, no content), the network of text messages (time of message, no content), and information about Facebook friendships. Thus, we provide multiple types of communication networks expressed in a single, large population with high temporal resolution, and over a period of multiple weeks, a fact which makes the dataset shared here unique. We expect that reuse of this dataset will allow researchers to make progress on the analysis and modeling of human social networks.本数据集呈现的是一个多层时序网络（multi-layer temporal network），该网络覆盖700余名大学生群体，采集周期为四周。本数据集通过智能手机采集，作为哥本哈根网络研究（Copenhagen Networks Study）的组成部分。本次数据集包含四类数据：一是参与者间通过蓝牙信号强度估算得到的物理邻近网络；二是包含通话起始时间与时长（不含通话内容）的电话通话网络；三是包含短信发送时间（不含短信内容）的短信网络；四是Facebook好友关系信息。因此，本数据集在大规模同质性群体中提供了多类型通信网络数据，且兼具高时间分辨率与多周的采集周期，这一特性使得本次共享的数据集独具特色。我们期望本数据集的复用能够助力研究者在人类社会网络的分析与建模领域取得进展。
