Social media, online news and the comment space are having far-reaching effects on the manner in which individuals and communities communicate, organize and express themselves. Can the information circulating on these platforms be tapped to better understand and analyze the enormous problems facing our contemporary society? Could this help us to better monitor the growing number of social crises due to differences in culture and diverging world-views? Would this allow an early detection and perhaps even ways to resolve conflicts before they lead to violence? These are the main questions of the European Porject, Opinion Dynamics and Cultural Conflict in European Spaces (ODYCCEUS).
