It’s been one of the buzzwords of recent weeks (months?). Big Data makes a lot of talk, but also a lot of dreams. Behind this word hides the incredible amount of data available, especially on the net. And above all the way in which it can be processed to obtain useful information. Trends in society, consumption, uses or opinions, epidemics… Everything is potentially possible. The key is knowing how to use this data, knowing where to look and how to do it. A very simple example that can illustrate this concept is Google Flu .
The search engine has thus set up indicators making it possible to follow the spread of the flu throughout the world, based on the searches launched on its engine. Yes, but… If Big Data seems to represent for some one of the major challenges of the next decade, not everyone agrees on this point. Obviously complicated to distinguish between useful and useless data, to know where to look, and in the end to provide relevant information. The first problem in terms of information being, according to the strategist Alan Mitchell (relayed in an exciting paper by Internet Actu) to bring the right information to the right person, and not necessarily to process a multitude of data.
Big Data Makes a Lot of Talk
Hence the opposition between Small Data and Big Data. The second question that arises concerns the opposition between organizations (main beneficiaries and users of Big Data) and individuals. General and impersonal statistics that will not adapt to the unique cases Japan WhatsApp Number of each one. Does all this remind you of anything? The announcement of Facebook Graph Search yesterday relies heavily on this concept of Big Data and mass processing of information. Except that it is more centered on the individual, and brings to the surface a lot of personal information.
Big Data Seems to Represent
Tomorrow, they will therefore be exploited, sorted and analyzed to give them meaning. The project will of course raise its share of problems, between the outdated data, the incomplete information given by many and the interest not necessarily existing for most of the information thus put forward (personally, knowing the films that my friends under 25 living in Montpellier does not interest me). But above all, it will bring up a lot of personal data that you do not necessarily want to expose to everyone, whether they were public one day or not.
And even less to give them meaning by allowing them to be matched. This is where the question of digital identity will take on its full meaning, that of confidentiality too… But back to our subject, namely the proliferation of online data. The IDC firm , commissioned by EMC (specialist in software and storage systems), has carried out a study on the proliferation of this data and is already anticipating what this will bring in 2020. The results are particularly interesting.
