In recent years, analysis of data from social media has provided a wealth of information about phenomena at societal scale, at least to the extent to which interactions, intentions and beliefs measured on-line reflect their real-world counterparts. Data from Twitter, Facebook, Google+, and Weblogs in general have been used to predict elections, opinions and attitudes, movie revenues, andoscillations in the stock market, to cite few examples. Similar data provided insights into the mechanisms driving the formation of groups of interests, topical communities, and the evolution of social networks. They also have been used to study polarization phenomena in politics, diffusion of information and the dynamics of collective attention.
