  abstract  = {This paper presents our Chinese-to-Japanese patent machine translation system
	for WAT 2016 (Group ID: ntt) that uses syntactic pre-ordering over Chinese
	dependency structures. Chinese words are reordered by a learning-to-rank model
	based on pairwise classification to obtain word order close to Japanese. In
	this year’s system, two different machine translation methods are compared:
	traditional phrase-based statistical machine translation and recent
	sequence-to-sequence neural machine translation with an attention mechanism.
	Our pre-ordering showed a significant improvement over the phrase-based
	baseline, but, in contrast, it degraded the neural machine translation
	baseline.},
