This paper describes the phrase-based SMT systems developed for our participation in the WMT12 Shared Translation Task. Translations for English↔German and English↔French were generated using a phrase-based translation system which is extended by additional models such as bilingual, fine-grained part-of-speech (POS) and automatic cluster language models and discriminative word lexica. In addition, we explicitly handle out-of-vocabulary (OOV) words in German, if we have translations for other morphological forms of the same stem. Furthermore, we extended the POS-based reordering approach to also use information from syntactic trees.
