We present an extension of phrase-based statistical machine translation models that enables the straight-forward integration of additional annotation at the word-level — may it be linguistic markup or automati- cally generated word classes. In a num- ber of experiments we show that factored translation models lead to better transla- tion performance, both in terms of auto- matic scores, as well as more grammatical coherence.
