Human face-to-face interaction network.
Using active RFID tag and a dedicated experimental apparatus thanks to the collaboration to the Sociopatterns project (http://www.sociopatterns.org), data of time-resolved person-to-person interaction networks were collected at conferences, schools, hospital wards to analyze their dynamics. Behavioral characteristics can hence be studied, for instance in a school to quantify interaction between children. Having only one realization of these networks, we developed a bootstrapping method using constrained graphs to probe with statistical confidence the behavior of a group in such a network.
