Thanks in great part to IBM's Watson technology and its ability to answer queries presented in natural language, artificial intelligence (AI) has received much attention in the past few years. This was especially true after Watson competed on the quiz show Jeopardy! in 2011 and won against prior champions. Watson evolved from IBM's DeepQA project and the Deep Blue chess computer that defeated chess champion Garry Kasporov in 1997.
Watson, whose design goal was to win at Jeopardy!, had major enhancements including the ability to leverage natural language processing, data retrieval, massively parallel processing, as well as access to vast amounts of structured and unstructured data. It also could generate hypotheses and "learn" from it results in order to modify and improve its logic and algorithms.
