As a result of our tests on English-Japanese (enja) and Japanese-English (ja-en) machine translation, we find that a T2S system not considering these elements performs only slightly better than a standard PBMT system.
after accounting for all these elements we see large increases of accuracy, with the final system greatly exceeding not only standard PBMT, but also state-of-the-art methods based on syntactic pre-or post-ordering.
