DeepQA was a project by IBM to develop a software architecture that could answer questions over a wide range of subjects in human rather than computer terms. Watson, the product of DeepQA, uses machine learning and natural language processing to answer questions, quickly extract information, and analyze large amounts of unstructured data. Recent applications of Watson stretching from healthcare to customer service have been upshots of DeepQA technology. In 2011, Watson defeated Jeopardy champions Ken Jennings and Brad Rutter to win the 1 million dollar Jeopardy prize.
