... the reordering model is that it can better model global phrase reordering using a four-valued reordering pattern, and it can be easily 718 Figure 5: BLEU score for the clustered and lexical reordering ... their model, the global reordering is not explicitly modeled. In this paper, we present a global reordering model that explicitly models long distance re- orde...

The target language model ... re- orderings for the discussed constraints is listed as a function of the sentence length. We see that for longer sentences the ITG constraints allow for more reorderings than th...
