Analysis of changes of opinions and social network structure of NetSense experiment participants — •Bartłomiej Zwoliński and Piotr Górski — Faculty of Physics, Warsaw University of Technology, Warsaw, 00-662 Poland

We study the interrelation between interactions and opinions by using data on Bluetooth contacts between college freshmen. We research evolution of social network structure and their opinions on eight topics within two-year period.

We find weak but significant correlation between students' vectors of opinions and their further interactions. Higher number of interactions had different impact on students' opinions depending on the period of the study, polarising them or leading to opinion alignment.

Throughout the experiment, we observed change of the students' contact network from overall community to smaller groups worse interconnected with each other.
