We evaluate two dependency parsers, MSTParser and MaltParser, with respect to their capacity to recover unbounded de- pendencies in English, a type of evalu- ation that has been applied to grammar- based parsers and statistical phrase struc- ture parsers but not to dependency parsers. The evaluation shows that when combined with simple post-processing heuristics, the parsers correctly recall unbounded dependencies roughly 50% of the time, which is only slightly worse than two grammar-based parsers specifically de- signed to cope with such dependencies.
