In our experiments, the phrase-based MT system uses an un-lexicalized reordering model, which might make the effects of the syntactic reordering method more pronounced.
in an early experiment 4 submitted to the official NIST 2006 MT evaluation, the reordered system also improved the BLEU score substantially (by 1.34 on NIST 2006 data) over a phrase-based MT system with lexicalized reordering models .
