Sentimento, analisi ed elezioni

Abstract

Since search engines and social networks have started being widely used by an enormous amount of users, advertising has always been their primary business model: presenting the “right” ad to the right user, especially focusing on her interests. We assisted therefore to an important and pivotal change from the generically focused traditional advertising industry to a highly specific way to match ads and users, thanks to personal data the same users convey for free to search engines and social networks. Advanced sentiment analysis techniques allow these same service providers to target their users with extremely personal political contents, therefore influencing democracy at a level that should be carefully taken into account.
