Resumen:  The rise of social media has changed the way people express their views and their opinions. Facebook, Twitter and other social media can be considered as an important source of information about what people think. For this reason, in the last few years there has been an increase in studies on how to extract people opinions from qualitative textual data in order to explore and forecast different real-world outcomes (as electoral results, stock market, audience behaviour, product performance etc.). The main statistical method to extract opinions of the web users, called Sentiment Analysis, and some of its scientific applications will be presented.
