The article, entitled “How to measure sessions of mobile phone use: Identification, evaluation, and applications”, has been published on Mobile Media & Communication by Jonathan Zhu, Hexin Chen, Taiquan Peng, Haixing Dai, and Xiaofan Liu. They proposed a variable-length measure called “session” to uncover unmeasured temporal characteristics of mobile phone use. An open source dataset was used to demonstrate how to quantify sessions, aggregate the sessions to higher units of analysis within and across users, evaluate the results, and apply the measure for theoretical or practical purposes.
