  abstract  = {This paper describes the NICT-2 translation system for the 3rd Workshop on
	Asian Translation.  The proposed system employs a domain adaptation method
	based on feature augmentation.              We regarded the Japan Patent Office
	Corpus as a
	mixture of four domain corpora and improved the translation quality of each
	domain.  In addition, we incorporated language models constructed from Google
	n-grams as external knowledge. Our domain adaptation method can naturally
	incorporate such external knowledge that contributes to translation quality.},
