“Fueled by big data collected by a wide range of high-throughput tools and technologies, a new wave of data-driven, interdisciplinary science have rapidly proliferated during the past decade, impacting a wide array of disciplines, from physics and computer science to cell biology and economics. In particular, the ICT’s are inundating us with huge amounts of information about human activities, oering access to observing and measuring human behavior at an unprecedented level of details. These large-scale datasets, oering objective description on human activity pat- terns, have started to reshape, and are expected to fundamentally alter, our discussions on quantifying and understanding human behavior. An impressive shift has been witnessed in statistical physics and complex system theory since the beginning of the new millennium, when the possibility of analyzing large datasets of human activities and social interactions has boosted a renewed interest in the study of human mobility on one side, and of social networks on the other side”
