DESCRIPTION:Pedro Ramaciotti\, Chair of AI in Social Sciences and Humaniti
 es at the French National Research Center CNRS\nA large number of works ta
 ke interest in the role of social media platforms – including their affo
 rdances\, particular culture\, and algorithmic mediation – on phenomena 
 such as the segregation of political communities\, polarization\, and lack
  of diversity of news diets. Behind this new field of studies\, an importa
 nt methodological lever is the political characterization of users and con
 tent into Left-Right or Liberal-Conservative scales and communities. In th
 is talk\, we will review the work of the European Polarisation Observatory
  (EPO)\, an initiative led by Sciences Po and CNRS together with seven add
 itional partners in Europe.\n\nOne of the main activities of the EPO is th
 e production of populations of social media users in different countries\,
  mapped onto several comparable ideology and issue dimensions: Left-Right\
 , attitudes towards the EU\, immigration\, environmental protection\, or t
 rust in elites and institutions\, to name a few. These populations\, mappe
 d along the dimensions that are relevant for different case studies in dif
 ferent national contexts\, constitute the basis for different works carrie
 d out at EPO. We will illustrate some of these works with studies regardin
 g the political dimensionality related to the spread of misinformation onl
 ine\, the cartography of political competition online\, and the mapping of
  profiles learned by algorithms computing recommendation in social media.\
