Sino-Japanese machine translation device, Sino-Japanese machine translation method, and Sino-Japanese machine translation program

摘要

A Japanese-to-Chinese machine translation apparatus includes an unregistered word determining unit that determines whether a Japanese word of a Japanese sentence is an unregistered word not registered in a Japanese-to-Chinese translation dictionary. The Japanese-to-Chinese translation dictionary contains Japanese words into which the Japanese sentence is divided, associated with Chinese words. The apparatus also includes an unregistered-word translation generating unit that, when the unregistered word determining unit determines that the Japanese word is the unregistered word, divides the unregistered word into a hiragana string and a non-hiragana string, generates a translation of the non-hiragana string, and does not generate a translation of the hiragana string.
