Importance of Data Science in today’s world
A majority of organizations carry out business based on insights gained from data analysis. Nowadays, the digital universe has experienced a huge shift in the size, type and form of data and in the way data is analyzed. Among stunning facts showing the data explosion tendency, it is worth mentioning that (i) unstructured data is doubling every three months, (ii) the year 2011 saw 47 percent overall growth and (iii) by 2015 the number of networked devices will be twice the global population. Moreover, another example of proliferating and valuable data source is represented by social media. For instance, the 300 millions of tweets processed daily by Twitter and the huge amount of data generated every day by the 585 million Facebook active users, represent a gold mine for businesses that make value out of advertisement and users habits.The Data Scientist professional figure comes into play when the need of extracting valuable insights from a huge amount of data emerges. From the figures mentioned above, and from the fact that data is nowadays considered as the “new oil”, it is not surprising that Data Scientist has been defined as the “sexiest job of 21st century”, according to a 2012 Harvard Business Review article. In the workshop, we will describe the most important skills required by companies that are looking for Data Scientist profiles. Furtherly, we will examine why a professional figure having a PhD background can be considered as a good candidate to cover a Data Scientist position. Finally, an overview of the most common applications in which Data Science gives its highest contribution will be given.
