Analyzing Mobile Phone Data With Network Science

• In Event: Temporal and Spatial Analysis of Mobility Data

Abstract

With the widespread use of mobile computing devices in contemporary society, our trajectories in the physical space and virtual world are increasingly closely connected. In the perspective of network science, we can study the communication network, mobility network, and attention network using the anonymous smartphone data. Using the anonymous smartphone data of 10,000 users in a major city of China, we study the interplay between online and offline human behaviors by constructing the mobility network (offline) and the attention network (online). Using the network renormalization technique, we find that they belong to two different classes: the mobility network is small-world, whereas the attention network is fractal.
