Abstract
A machine translation method includes translating a source sentence using a first model, determining a back-translation probability of a translation result of the source sentence being back-translated into the source sentence using a second model, applying the back-translation probability to context information extracted from the source sentence in the first model, and retranslating the source sentence using the first model and the context information to which the back-translation probability is applied.
Claims23
A processor-implemented machine translation method comprising:
- translating a source sentence using a first model;
- determining a back-translation probability of a translation result of the source sentence being back-translated into the source sentence using a second model;
- applying the back-translation probability to context information extracted from the source sentence in the first model;
- and
- retranslating the source sentence using the first model and the context information to which the back-translation probability is applied,
- wherein the back-translation probability is determined for each of words included in the source sentence.
A machine translation apparatus comprising:
- a processor;
- and
- a memory storing at least one instruction to be executed by the processor,
- wherein the processor executing the at least one instruction configures the processor to:
- translate a source sentence using a first model;
- determine a back-translation probability of a translation result of the source sentence being back-translated into the source sentence using a second model;
- apply the back-translation probability to context information extracted from the source sentence in the first model;
- and
- retranslate the source sentence using the first model and the context information to which the back-translation probability is applied,
- wherein the processor is further configured to determine the back-translation probability for each of words included in the source sentence.
A processor-implemented machine translation method comprising:
- translating a source sentence comprising words based on context information of the words of the source sentence using a first model to obtain a target sentence;
- determining a back-translation probability of the target sentence being back-translated into the source sentence using a second model;
- applying the back-translation probability to the context information to obtain modified context information;
- and
- retranslating the source sentence based on the modified context information using the first model to obtain an updated target sentence.
