Web Science Summer School - Fifth keynote speech from Dr Chris Welty

Dr Chris Welty will give the fifth keynote on Thursday morning in Nightingale building. He is a Research Scientist at the IBM T.J. Watson Research Center in New York. His principal area of research is Knowledge Representation, specifically ontologies and the semantic web, and he spends most of his time applying this technology to Natural Language Question Answering as a member of the DeepQA/Watson team and, in the past, Software Engineering. The abstract for his speech is below: Watson is a computer system capable of answering rich natural language questions and estimating its confidence in those answers at a level rivalling the best humans at the task. On Feb 14-16, 2011, in an historic event, Watson triumphed, in a widely televised broadcast of the American quiz show Jeopardy!, over the best human players of all time. In this talk I will discuss how Watson works at a high level with examples from the show, and concentrate on the use of semantic technology in Watson.
