Another QA system enjoying wide recognition because of its televised victory in the Jeopardy! quiz show is IBM's “Watson” (Ferrucci 2012; Ferrucci et al. 2010; Baker 2011). Like Wolfram|Alpha, this is in a sense a brute force program, consisting of about a million lines of code in Java, C++, Prolog and other languages, created by a core team of 20 researchers and software engineers over the course of three years. The program runs 3000 processes in parallel on ninety IBM Power 750 servers, and has access to 200 million pages of content from sources such as Wordnet, Wikipedia (and its structured derivatives YAGO and DBpedia), thesauri, newswire articles, and literary texts, amounting to several terabytes of human knowledge. (This translates into roughly 1010 clausal chunks—a number likely to be around 2 orders of magnitude greater than the number of basic facts over which any one human being disposes.)
