This paper describes the German-English translation system developed by the ARK research group at Carnegie Mellon University for the Sixth Workshop on Machine Translation (WMT11). We present the results of several modeling and training improvements to our core hierarchical phrase-based translation system, including: feature engineering to improve modeling of the derivation structure of translations; better handing of OOVs; and using development set translations into other languages to create additional pseudo-references for training.
