We present a novel model of transliteration min- ing defined as a mixture of a transliteration model and a non-transliteration model. The transliteratio...

... different qualities. For example, both topic “css test” and “test suite” are the bi-gram matching for query “css test suite”; however, the former might be more informative. To model that, we use ... following sub-sections, we will detail two sub-models: the expert matching model P(c|e) and the evidence matching model P(e|q). 3.2 Expert Matching Model We expand the evidence...

Thus, if there is an error in the database, it is more likely that other errors will be for the same languages. In order...
