Also, many researches about transliteration have been accomplished for clean data, however, as far as we know, there have been no research about transliteration for noisy query data.
we investigated which method is the best for query transliteration, using the parallel data of the alphabetic queries which did not provide any products when non-Japanese people searched (i.e., the Alphabet Queries) and the Japanese queries which are transcribed from them (i.e., the Correct Queries).
