Data analytics have interesting applications. Here is one famous example of data analytics in action.
Watson is a computer system created by a team of 25 IBM scientists over four years. In 2011, Watson competed against Ken Jennings for Brad Rutter on the game show Jeopardy (see Figure 1.5) in a three-day tournament and won. Watson received the clues as electronic texts at the same time they were made visible to Ken and Brad. Watson would then parse the clues into different keywords and sentence fragments in order to find statistically related phrases. Watson won by using its ability to quickly execute thousands of language analysis algorithms simultaneously to compile potential answers and determine its level of confidence in any given answer.
