Syntax- based MT often suffers from inadequate constraints in the translation rules extracted, or from striving to combine these rules together towards ... applicable to phrase-pair emission rules and features for both translation directions are used, while (d) is only triggered by structural rules. These extra features assess translatio...

... is possible for translation models to contain “unnecessary” translations. In this paper, we attempt to identify and decrease the pro- portion of unnecessary translations in a translation model ... in modeling the translation of phrases as a whole. More precise translation can be determined for phrases than for words. It is thus reasonable to expect that using such phrase translation...

We propose a metric that evaluates ...
