hmm word and phrase alignment for statistical machine translation
Yonggang Deng William Byrne
The idea of introducing constraints over a model to better guide the learning process has appeared before . In the context of word alignment , Deng and Byrne ( 2005 ) use a state-duration HMM in order to model word-to-phrase translations . The fertility of each source word is implicitly encoded in the durations of the HMM states .
