What Big Data Is and How Can We Use It

di Luigi Laura

In recent years, we have witnessed an exponential growth of the amount of data we are generating. As an example, consider the numbers depicted in Figure 1, that shows what happens in one minute in Internet, for both the years 2016 and 2017. In a single minute, approximately 150 million email are sent, 350 thousand new tweets appear in Twitter, and 40 thousand posts in Instagram, both in 2016 and in 2017. But the figure allows us also to see the impressive growth, in a single year, of some statistics: the search queries in Google raised from 2.4 to 3.5 million, video views in Youtube jumped from 2.78 to 4.1 million, and Uber Rides almost triplicated, from approximately 1300 to 3800. WhatsApp messages exchanged went from 20 to 29 million. There is an explosion of data, and the natural question is whether we can use it to improve our daily lives. We already witnessed some examples in which we can exploit the data: Google Maps has real time information about traffic data, and suggests us the fastest route available according to this info. Amazon knows what we bought, i.e., what we like, and can suggest us similar items based on shopping preferences of people that have similar tastes. Apple (and other companies) can recognize our friends in the pictures, that are geolocalized thanks to the built-in GPS in our smartphones, and helps us in retrieving and organizing them. We choose restaurants and hotels based on the feedback of thousands of customers in Tripadvisor. Big Data is already in our lives. In the following section, we will try to provide a better picture of what Big Data is. Then, the natural question become “How can we use it?”
