... 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 the proposed models, we train for 100 iterations, and use the ... discrimi- native model that performs joint word alignment and phrase extraction, and found that joint estimation of word alignments and extraction sets improves both wor...

... 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 ... distribu- tion and require supervised/semi-supervised infor- mation for learning. We propose a flexible genera- tive model for transliteration mining usable for both unsuperv...
