The international has turn into electronic and technological advances have increased circuits with entry to info, their processing and their diffusion. New applied sciences have now reached a undeniable adulthood. facts can be found to every person, wherever on this planet. The variety of web clients in 2014 used to be 2.9 billion or forty-one% of the area inhabitants. the necessity for wisdom is changing into obvious on the way to comprehend this multitude of information. We needs to train, tell and educate the loads. the improvement of similar applied sciences, comparable to the appearance of the web, social networks, "cloud-computing" (digital factories), has elevated the to be had volumes of information. at present, each one person creates, consumes, makes use of electronic info: greater than 3.4 million e-mails are despatched around the globe each moment, or 107,000 billion every year with 14,600 e-mails in keeping with 12 months according to individual, yet greater than 70% are unsolicited mail. Billions of items of content material are shared on social networks comparable to fb, greater than 2.46 million each minute. We spend greater than 4.8 hours an afternoon on the net utilizing a working laptop or computer, and 2.1 hours utilizing a cellular. info, this new airy manna from heaven, is produced in actual time. It is available in a continuing flow from a mess of assets that are normally heterogeneous.
This accumulation of knowledge of every kind (audio, video, documents, pictures, etc.) generates new actions, the purpose of that's to research this huge, immense mass of knowledge. it's then essential to adapt and check out new ways, new equipment, new wisdom and new methods of operating, leading to new homes and new demanding situations for the reason that website positioning good judgment has to be created and applied. At corporation point, this mass of information is hard to control. Its interpretation is essentially a problem. This affects those who find themselves there to "manipulate" the mass and calls for a selected infrastructure for production, garage, processing, research and restoration. the largest problem lies in "the valuing of information" to be had in volume, variety and entry speed.

It is possible to obtain better results by making better use of available data. Twitter has become a popular source for Big Data exploitation, but working with Twitter data represents a huge methodological challenge that is seldom taken up. 3. A methodological challenge: Twitter When researchers encounter a set of data, they need to understand not only the limits of the available set of data, but also the limits of the questions that it can respond to, as well as the range of possible appropriate interpretations.
2 In this sense, Viktor Mayer-Schönberger has underscored the difficulty in quantifying the value of data in his book, Big data, A Revolution That Will Transform How We Live, Work and Think. 4 Big Data, Open Data and Data Development scholars add another three “Vs”, namely3: “Variability”, “Veracity”, and “Visualization”. The first V refers to data whose meaning evolves constantly. The second qualifies the result of the data’s use, since even though there is a general consensus about the potential value of Big Data, data has almost no value at all if it is not accurate.
Interpreting this large volume of data is the greatest challenge facing Big Data, since information resulting from it can be the basis for new knowledge that brings about development opportunities. Technology now offers a perspective on data as structured and therefore, static. Technological limits, in terms of performance and storage, reduce the scope of possible analysis to sets of explicit data. Most solutions provide the couple: “storage and processing”. It is worth noting that growth in the volume of data has been accompanied by a reduction in the price of storage.
