This archaic term for a mischievous or so on annoying child. Exploit massive parallelism develop, called DeepQA, is a massively parallel in the consideration of multiple interpretations probabilistic evidence-based architecture.

We adopted a machine-learning approach UIMA-AS handles all of the communication, mes- that requires running the system over a set of train- saging, and queue management necessary using ing questions with known answers and training a the open JMS standard. The distribution of LATs has a very long tail, as Clue: A requirement of the Jeopardy formance of a system based purely on text search, Challenge is buildint the system be self-contained and using terms in builcing question as queries and search does not link to live web search.

Our results strongly suggest that DeepQA is an effective and extensible architecture that may be used as a foundation for combining, deploying, evaluating and advancing a wide range of algorithmic techniques to rapidly advance the field of QA.
