DESCRIPTION:At this session of the NLIP Reading Group we'll be discussing 
 the following paper:\n\nRonald M. Kaplan\, Stefan Riezler\, Tracy Holloway
  King\, John T. Maxwell III\, Alexander Vasserman and Richard Crouch. 2004
 . "Speed and Accuracy in Shallow and Deep Stochastic Parsing":http://aclwe
 b.org/anthology-new/N/N04/N04-1013.pdf. In Proceedings of NAACL-HLT-04.\n\
 n*Abstract:*\nThis paper reports some experiments that compare the accurac
 y and performance of two stochastic parsing systems. The currently popular
  Collins parser is a shallow parser whose output contains more detailed se
 mantically relevant information than other such parsers. The XLE parser is
  a deep-parsing system that couples a Lexical Functional Grammar to a logl
 inear disambiguation component and provides much richer representations th
 eory. We measured the accuracy of both systems against a gold standard of 
 the PARC 700 dependency bank\, and also measured their processing times. W
 e found the deep-parsing system to be more\naccurate than the Collins pars
 er with only a slight reduction in parsing speed.
