Every day, we create 2.5 quintillion bytes of data.* This data comes from everywhere—from posts to social media sites, digital pictures and videos posted online, and cell phone GPS signals, to name a few. The amount of data in our world has been exploding. Analyzing large data sets, so called “big data,” becomes a key basis of competition and innovation. The question is: How are we going to harvest all this data? Traditional BI is too clumsy to get the job done. Why?
Every day, we create 2.5 quintillion bytes of data.* This data comes from everywhere—from posts to social media sites, digital pictures and videos posted online, and cell phone GPS signals, to name a few.

Every few minutes, the system searches the world’s newly posted blog entries for occurrences of the phrases “I feel” and “I am feeling” and stores 15,000 to 20,000 new emotions per day. I used the API to extract the data (in QlikView, developers can define web files as data source). Then I started asking questions and exploring this unstructured data.
Do women feel fat more often than men? Does rainy weather affect how we feel? What are the happiest cities in the world? Do Europeans feel sad more often than Americans? You can download my application from QlikCommunity, to ask your own questions and formulate your own insights about the human condition.
