... Linguistics. Chris Quirk, Arul Menezes, and Colin Cherry. 2005. De- pendency treelet translation: Syntactically informed phrasal smt. In Proceedings of 43rd Annual Meeting of the Association for ... Note that we do not prune the phrase-pair emitting rules. Over- all, we consider this a much more informed pruning criterion than those based on probability values (that are not compar...

... Several researchers have subsequently formulated models which incor- porate the intuition that syntactically close con- stituents tend to stay close across languages. Below are descriptions of ... a couple of these in the near future. Among these are discontinuous constituents, head switching, phrasal translation, English word stemming, and improved modeling of structural changes. Acknowl...

The predicate ... according to the error study by Wu and Fung (2009a). This suggests that conventional lexical and phrasal translation models adopted in those SMT systems are not sufficient to correctly tra...
