Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for adjusting transliteration weights. One methods includes maintaining transliteration rules and a weight for each rule and receiving training pairs comprising a first word in a first writing system and a second word in a second writing system, where the second word is a transliteration of the first word. The method further includes processing the training pairs to determine, for each transliteration rule, one or more good weight adjustments and one or more bad weight adjustments, and for one or more of the transliteration rules, selecting a good weight adjustment for the transliteration rule that has a highest associated gain and updating the weight for the transliteration rule to reflect the selected good weight adjustment for the rule.
