Eric Brown, IBM Research Scientist working on the DeepQA project which created the Watson Jeopardy playing system spoke at a NEOSA Tech Week event in Cleveland. Brown explained how they evaluate and authorize data sources and that the natural learning of Watson contributes to this though an attempt to use the Urban Dictionary was scuttled -- by humans. http://www.greatlakesgeek.com/other/reviews/events.htm
