... present a novel model of transliteration min- ing defined as a mixture of a transliteration model and a non-transliteration model. The transliteration model is a joint source channel model (Li et ... labelled information for training. Our sys- tem extracts transliteration pairs in an unsupervised fashion. It is also able to utilize labelled information if available, obtaining improv...

... all models, and for the LM we use an interpolated Kneser-Ney 5-gram model. For GIZA ++, we use the standard training reg- imen up to Model 4, and combine alignments with grow-diag-final-and. For ... noted that forcing align- ments smaller than the model suggests is only used for generating alignments for use in heuristic extrac- tion, and does not affect the training process. 5...
