DESCRIPTION:At this session of the NLIP Reading Group we’ll be discussin
 g the following paper:\n\nJoakim Nivre. 2005. "Dependency grammar and depe
 ndency parsing":http://stp.lingfil.uu.se/~nivre/docs/05133.pdf. Technical 
 Report\, School of Mathematics and Systems Engineering\, Växjö Universit
 y.\n\n*Abstract:* \nDespite a long and venerable tradition in descriptive 
 linguistics\, dependency grammar has until recently played a fairly margin
 al role both in theoretical linguistics and in natural language processing
 . The increasing interest in dependency-based representations in natural l
 anguage parsing in recent years appears to be motivated both by the potent
 ial usefulness of bilexical relations in disambiguation and by the gains i
 n efficiency that result from the more constrained parsing problem for the
 se representations. In this paper\, we will review the state of the art in
  dependency-based parsing\, starting with the theoretical foundations   of
  dependency grammar and moving on to consider both grammar-driven and data
 -driven methods for dependency parsing.\n\nAs this is a longer-than-usual 
 paper\, Laura and Andreas have provided the following reading suggestions:
 \n\nOur purpose in presenting this technical report is to give an introduc
 tion to dependency grammars and how they are used in parsing. It is worth 
 reading in its entirety\, but we'd like to focus on pages 1-5 (intro and s
 ome definitions)\, 10-11 (notion of projectivity and syntactic vs semantic
  heads) and 19-24 (data-driven dependency parsing and conclusions).
