Nowadays, Facebook and Twitter, two of the largest social networks in the world, already have more than 1 billion users and more than 340 million posts daily (Zephoria. 2017). Consequently, the amount of data available is growing every day. With the easiness of access (through mobile devices), users update their profile almost in real time. Therefore, there are many relevant events reported first through social networks post, and only then reported in journalistic media sources. Wherefore, it is necessary to detect this kind of information at early stages.

In project REMINDS we will develop systems to perform an analysis of public information transmitted through Social Networks, to automatically filter and show the information that is potentially relevant to a general audience.
