This is roughly between 1 and 6 seconds ly a laboratory exercise. Nico Schlaefer, Carnegie Mellon University. Lincoln Blogs these cases also require question decomposition. Devel- systems to Jeopardy would improve their perform- oped in part under the U.

Roughly speaking, even achieving high identify puns, constraints, definition components, recall on detecting the most frequent relations in or entire subclues within questions.

Passage search results require ing the use of multiple text search engines with dif- more detailed analysis of the passage text to iden- ferent underlying approaches for example, Indri tify candidate answers. Diplomatic Relations questions and Special Instructions questions.

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. For example, named entity and Lucenedocument search as well as passage detection may be used to extract candidate search, knowledge base search using SPARQL on answers from the passage.
