On July 30, Center Director, Dr. Boleslaw Szymanski presented an invited paper titled “Interaction Patterns in a Multilayer Social Network” co-authored Ashwin Bahulkar at the 27th International Conference on Computer Communications and Networks (ICCCN 2018) in Hangzhou,China. The paper studies the interaction patterns among university students whose interactions are recorded in an aligned multilayer social network. One layer of this network represents the smartphone communications, including calls and text messages. The other layer represents face-to-face interactions. The paper analyzes this multilayer network to find whether communication and face-to-face interactions are correlated, and what impact the aging, that is the growing over time familiarity of each node with its peers, has on students’ interaction patterns. It also investigates to what extent the academic year structure and external events, such as holidays, affect the network and the interactions between the nodes, and how the individual’s communication pattern profile varies as a function of the node’s degree and intensity of its interactions. The results described in the paper shed a light on how students’ interaction patterns are impacted by the structure of a social network, its age, and social profiles of its nodes.
