چکیده
|
We propose three novel reordering models for statistical machine translation. these reordering models use dependency tree to improve the translation quality. all reordering models are utilized as features in a log linear framework and therefore guide the decoder to make better decisions about reordering. these reordering models are tested on two english-persian parallel corpora with different statistics and domains. the bleu score is improved by 2.5 on the first corpus and by 1.2 on the other.
