Machine translation method for performing translation between languages

A machine translation method comprising:

• receiving a translation-source sentence in a first language;
• generating a plurality of different forward-translated sentences resulting from translation of the received translation-source sentence into a second language;
• generating a plurality of backward-translated sentences resulting from backward translation of the plurality of different forward-translated sentences into the first language;
• and
• outputting, upon receiving an operation for selecting one of the plurality of backward-translated sentences during output of the plurality of backward-translated sentences on an information output device, a forward-translated sentence corresponding to the selected backward-translated sentence to the information output device,
• wherein the information output device has a display,
• wherein the method further comprising:
• displaying the plurality of backward-translated sentences in a first area on the display;
• and
• displaying the translation-source sentence in a second area on the display, the second area being different from the first area.

A machine translation method comprising:

• receiving a translation-source sentence in a first language;
• generating a plurality of different forward-translated sentences resulting from translation of the received translation-source sentence into a second language;
• generating a plurality of backward-translated sentences resulting from backward translation of the plurality of different forward-translated sentences into the first language;
• and
• outputting, upon receiving an operation for selecting one of the plurality of backward-translated sentences during output of the plurality of backward-translated sentences on an information output device, a forward-translated sentence corresponding to the selected backward-translated sentence to the information output device,
• wherein the receiving includes receiving, as the translation-source sentence, voice information via a microphone that receives a voice input performed by a user, or receiving, as the translation-source sentence, text information via a text input device that receives a text input performed by a user,
• wherein the method further comprising:
• generating a forward-translated sentence group that is a collection of forward-translated sentences resulting from translation of the received translation-source sentence into the second language, the forward-translated sentence group including the plurality of different forward-translated sentences;
• determining a subject or a predicate in each forward-translated sentence included in the forward-translated sentence group;
• and
• determining the plurality of different forward-translated sentences in the forward-translated sentence group, based on the determined subject or predicate.

A machine translation method comprising:

• receiving a translation-source sentence in a first language;
• generating a plurality of different forward-translated sentences resulting from translation of the received translation-source sentence into a second language;
• generating a plurality of backward-translated sentences resulting from backward translation of the plurality of different forward-translated sentences into the first language;
• and
• outputting, upon receiving an operation for selecting one of the plurality of backward-translated sentences during output of the plurality of backward-translated sentences on an information output device, a forward-translated sentence corresponding to the selected backward-translated sentence to the information output device,
• wherein the receiving includes receiving, as the translation-source sentence, voice information via a microphone that receives a voice input performed by a user, or receiving, as the translation-source sentence, text information via a text input device that receives a text input performed by a user,
• the method further comprising:
• generating a backward-translated sentence group that is a collection of at least one backward-translated sentence generated for each of the plurality of different forward-translated sentences, the backward-translated sentence group including the plurality of backward-translated sentences;
• calculating evaluation values obtained by evaluating similarities between the translation-source sentence and the at least one backward-translated sentence included in the backward-translated sentence group;
• and
• selecting the plurality of backward-translated sentences from the backward-translated sentence group, based on the evaluation values.
