Translation device and translation method

A translation device configured to translate from a first language into a second language and retranslate from the second language into the first language, by means of a translation server, the translation device comprising:

• a storage configured to store a word in the first language, a univocal in the first language for the word in the first language, a replaced translation word in the second language for the univocal, and a translation word in the second language for the word in the first language;
• a first language acquisition unit configured to acquire a sentence in the first language;
• a polyseme processor configured to determine whether or not the translation word for the word in the first language included in the sentence is a polyseme, and replace the word in the first language with the univocal to generate a replaced sentence in the first language when the translation word is determined as a polyseme;
• a communication unit configured to transmit the replaced sentence to the translation server, and receive, from the translation server, a replaced translation sentence in the second language generated by translation of the replaced sentence into the second language and including the replaced translation word, and a replaced retranslation sentence in the first language generated by retranslation of the replaced translation sentence into the first language and including the univocal;
• a first language output unit configured to output a retranslation sentence in the first language generated by replacement of the univocal included in the replaced retranslation sentence with the word in the first language;
• and
• a second language output unit configured to output a translation sentence in the second language generated by replacement of the replaced translation word included in the replaced translation sentence with the translation word.
