SUMMARY:Evaluation of Dependency Parsers on Unbounded Dependencies - Laura

DESCRIPTION:Joint work with Joakim Nivre\, Ryan McDonald and Carlos Gómez
 -Rodríguez.\n\nWe evaluate two dependency parsers\, MSTParser and MaltPar
 ser\, with respect to their capacity to recover unbounded dependencies in 
 English\, a type of evaluation that has been applied to grammar-based pars
 ers and statistical phrase structure parsers but not to dependency parsers
 . The evaluation shows that when combined with simple post-processing heur
 istics\, the parsers correctly recall unbounded dependencies roughly 50% o
 f the time\, which is only slightly worse than two grammar-based parsers s
 pecifically designed to cope with such dependencies.
