A control method includes receiving a sentence and link information about the sentence, outputting a first translation sentence by retranslating the sentence into a language corresponding to a user command by using a translation engine, in response to the translation engine being updated, generating a second translation sentence by retranslating the sentence, and outputting the second translation sentence and the link information. Therefore, the translation apparatus improves a quality of translation sentence, which is translated before a translation engine is updated, through the translation engine that is updated as a latest version.
