Abstract In last decades Europe has become one of principal continents of the phenomen of the immigration. Italy is one of the European countries most exposed to the phenomenon. If you consider the political, economic and social italian context in the last ten years, you can grasp how these demographic changes have come with "inter-group tensions" (Coenders, Lubbers and Scheepers 2003; Semyonov, Raijman and Gorodzeisky,2006) and consequetly a pervasive negative opinion on immigration developed sometimes in hate speech. However, while the literature is rapidly growing, the field is still confronted with inconclusive results and question marks about the relationship between public opinion and contextual factors (Marie-Sophie Callens, 2015). In this study, seven European countries (Italy, Uk, Croatia, Bulgaria, Romania, Greece & Czech Republic) have been compared on the basis of 10 common keywords through tweets, posts and social media in order to discover the nature and the trend of hate speech orientend to migrants.
