Negative expression translation in Japanese and Chinese machine translation

Because there are many differences between Chinese and Japanese about the nature, history, culture, life, manners and customs, it is natural that there are particular words in each language. It is necessary that these particular words meaning are mastered right and translated accurately in translation. Because of the complex corresponding relationship with Chinese in Chinese-Japanese machine translation, it is easy to occur a vagueness, due to the negative in the sentence, many mistranslations are caused by the commercial translation software. In this paper, we analyzed the negative expressionways in Chinese and Japanese languages to translate Chinese negative sentences by using the selection rules of Chinese negative words and position rules. If we translate the basic Japanese negative expression naide1 into Chinese, its meaning is mei2, bie. Translate nakute into Chinese, according to its negative meaning and grammatical rule, it may be translated into bu. In the current research, we investigated a rough use rules which abstracted from each typical examples including naide and nakute.
