IBM Watson is a question answering computer system created by IBM to apply natural language processing, information retrieval, knowledge representation and automated reasoning to answer questions posed in natural language. It consists of 90 IBM Power 750 servers with 2880 POWER7 cores and can operate at 80 teraflops. Watson was initially created to compete on the game show Jeopardy! where it won against human champions in 2011. It has since been applied to answering customer service questions, analyzing news and text, and providing medical diagnoses.
