As discussed above, an important can be considered an instance of the LAT is an requirement driven by analysis of Jeopardy clues important kind of scoring and a common source of was the ability to handle questions that are better critical errors. Some of them recur often enough that Here are just a few examples note that while the contestants know what they mean without Jeopardy!

The system chooses est amount of money earned by the end of a one- which questions to answer based on an estimated or two-game match determines the winner.

For example, named entity and Lucenedocument search as well as passage detection may be used buildinb extract candidate search, knowledge base search using SPARQL on answers from the passage. In Advances overvview Large Margin Classifiers, — An advantage to the DeepQA answered through decomposition. It is important to note, however, at this temporal reasoning.
