Description

Translation device and translation method

[0001] The present disclosure relates to a translation device and a translation method.

[0002] There is a translation device that translates an original text to be translated. For example, Patent Document 1 discloses a translation device that includes a processing control unit that translates an original text in a source language into a first language, displays the translation into the first language on a screen, and translates the translation into the first language back into the source language and displays the back-translation into the source language on a screen.

[0003] Japanese Patent Application Laid-Open No. 2001-318918

[0004] The translation device disclosed in Patent Document 1 is only intended to translate an original text written in a source language into a first language. Therefore, in order to translate an original text written in a source language into multiple languages, it is necessary to use multiple translation devices as disclosed in Patent Document 1. When using multiple translation devices as disclosed in Patent Document 1 to translate an original text written in a source language into multiple languages, if the back-translated text differs from the user's intention, the user must correct the original text in each of the multiple languages ​​to be translated. This means that the user has to perform the same correction work multiple times, which takes a long time to translate into multiple languages.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a translation device that can translate an original text to be translated into multiple languages ​​and reduce the time required to translate into multiple languages.

[0006] A translation device according to the present disclosure includes an original text acquisition unit that acquires an original text to be translated, a first translation unit that translates the original text acquired by the original text acquisition unit into a first language, a back translation unit that back-translates the translation by the first translation unit, a display processing unit that displays the back-translated text by the back translation unit on a display device, and a correction accepting unit that accepts corrections to the original text after the back-translation is displayed by the display processing unit. The translation device also includes a second translation unit that, when the corrections to the original text are accepted by the correction accepting unit, translates the corrected original text accepted by the correction accepting unit into a second language.

[0007] According to the present disclosure, an original text to be translated can be translated into multiple languages, and the time required for translation into multiple languages ​​can be reduced.

[0008] FIG. 1 is a configuration diagram showing a translation system including a translation device 1 according to embodiment 1. FIG. 2 is a hardware configuration diagram showing the hardware of the translation device 1 according to embodiment 1. FIG. 3 is a hardware configuration diagram of a computer in the case where the translation device 1 is realized by software, firmware, or the like. FIG. 4 is a flowchart showing a translation method which is a processing procedure of the translation device 1. FIG. 5 is a configuration diagram showing a translation system including a translation device 1 according to embodiment 2. FIG. 6 is a hardware configuration diagram showing the hardware of the translation device 1 according to embodiment 2.

[0009] In order to explain the present disclosure in more detail, embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0010] Embodiment 1. Fig. 1 is a configuration diagram showing a translation system including a translation device 1 according to embodiment 1. Fig. 2 is a hardware configuration diagram showing the hardware of translation device 1 according to embodiment 1. The translation system shown in Fig. 1 includes translation device 1, translation engine 2, and display device 3. Translation device 1 provides an original text to be translated to translation engine 2, obtains translations in multiple languages ​​from translation engine 2, and displays each translation on display device 3. When the original text to be translated is provided from translation device 1, translation engine 2 translates the original text into each language and outputs the translations in each language to translation device 1. Display device 3 displays the translations in each language, etc.

[0011] The translation device 1 includes an original text acquisition unit 11, a first translation unit 12, a back translation unit 13, a correction acceptance unit 14, a second translation unit 15, and a display processing unit 16. The original text acquisition unit 11 is realized, for example, by an original text acquisition circuit 21 shown in FIG. 2. The original text acquisition unit 11 acquires an original text to be translated. The original text acquisition unit 11 outputs the original text to be translated to the first translation unit 12, the correction acceptance unit 14, the second translation unit 15, and the display processing unit 16, respectively.

[0012] The first translation unit 12 is realized, for example, by the first translation circuit 22 shown in FIG. 2 . The first translation unit 12 acquires an original text to be translated from the original text acquisition unit 11. The first translation unit 12 translates the original text acquired by the original text acquisition unit 11 into a first language. Specifically, the first translation unit 12 provides the original text to be translated to the translation engine 2 and acquires a translation in the first language from the translation engine 2. In the translation system shown in FIG. 1 , the translation engine 2 is provided outside the translation device 1. However, this is merely an example, and the translation engine 2 may be provided inside the translation device 1. For example, if the first translation unit 12 includes a translation engine, the first translation unit 12 translates the original text to be translated into the first language. The first translation unit 12 outputs the translation in the first language to the back translation unit 13 and the display processing unit 16.

[0013] The back translation unit 13 is realized, for example, by the back translation circuit 23 shown in FIG. 2 . The back translation unit 13 obtains a translation in the first language from the first translation unit 12. The back translation unit 13 back-translates the translation by the first translation unit 12. Back translation is a process of translating the translation by the first translation unit 12 into the language used in the original text to be translated. Specifically, the back translation unit 13 provides the translation in the first language to the translation engine 2 and obtains the back-translated text from the translation engine 2. In the translation system shown in FIG. 1 , the translation engine 2 is provided outside the translation device 1. However, this is merely an example, and the translation engine 2 may be provided inside the translation device 1. For example, if the back translation unit 13 includes a translation engine, the back translation unit 13 back-translates the translation in the first language. The back translation unit 13 outputs the back-translated text to the display processing unit 16.

[0014] The correction accepting unit 14 is realized by, for example, the correction accepting circuit 24 shown in Fig. 2. The correction accepting unit 14 acquires the original text to be translated from the original text acquiring unit 11. The correction accepting unit 14 accepts corrections to the original text after the back-translated text is displayed by the display processing unit 16. The correction accepting unit 14 outputs the accepted corrected original text to each of the first translation unit 12 and the second translation unit 15.

[0015] The second translation unit 15 is realized by, for example, the second translation circuit 25 shown in FIG. 2 . If the correction receiving unit 14 has accepted a correction, the second translation unit 15 acquires the corrected original text from the correction receiving unit 14. If the correction receiving unit 14 has not accepted a correction, the second translation unit 15 acquires the Japanese original text from the original text acquisition unit 11. If the correction receiving unit 14 has accepted a correction, the second translation unit 15 translates the corrected original text accepted by the correction receiving unit 14 into the second language. If the correction receiving unit 14 has not accepted a correction, the second translation unit 15 translates the original text acquired by the original text acquisition unit 11 into the second language. Specifically, the second translation unit 15 provides either the corrected original text accepted by the correction receiving unit 14 or the original text acquired by the original text acquisition unit 11 to the translation engine 2, and acquires a translation in the second language from the translation engine 2. 1 , the translation engine 2 is provided outside the translation device 1. However, this is merely an example, and the translation engine 2 may be provided inside the translation device 1. For example, if the second translation unit 15 is provided with a translation engine, the second translation unit 15 translates either the original text corrected by the correction receiving unit 14 or the original text acquired by the original text acquisition unit 11 into the second language. The second translation unit 15 outputs the translation in the second language to the display processing unit 16.

[0016] The display processing unit 16 is realized by, for example, the display processing circuit 26 shown in Fig. 2. The display processing unit 16 displays the original text to be translated output from the original text acquisition unit 11 on the display device 3, and displays the translation in the first language output from the first translation unit 12 on the display device 3. The display processing unit 16 also displays the back-translation output from the back translation unit 13 on the display device 3, and displays the translation in the second language output from the second translation unit 15 on the display device 3.

[0017] 1, it is assumed that each of the components of the translation device 1, namely, the source text acquisition unit 11, the first translation unit 12, the back translation unit 13, the correction acceptance unit 14, the second translation unit 15, and the display processing unit 16, is realized by dedicated hardware as shown in Fig. 2. That is, it is assumed that the translation device 1 is realized by a source text acquisition circuit 21, a first translation circuit 22, a back translation circuit 23, a correction acceptance circuit 24, a second translation circuit 25, and a display processing circuit 26. Each of the original text acquisition circuit 21, the first translation circuit 22, the back translation circuit 23, the correction reception circuit 24, the second translation circuit 25, and the display processing circuit 26 may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination thereof.

[0018] The components of translation device 1 are not limited to those realized by dedicated hardware, and translation device 1 may be realized by software, firmware, or a combination of software and firmware. Software or firmware is stored as a program in the memory of a computer. A computer refers to hardware that executes a program, such as a CPU (Central Processing Unit), GPU (Graphics Processing Unit), central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, processor, or DSP (Digital Signal Processor).

[0019] 3 is a hardware configuration diagram of a computer when translation device 1 is realized by software, firmware, etc. When translation device 1 is realized by software, firmware, etc., programs for causing a computer to execute the respective processing procedures of original text acquisition unit 11, first translation unit 12, back translation unit 13, correction acceptance unit 14, second translation unit 15, and display processing unit 16 are stored in memory 31. Then, a processor 32 of the computer executes the programs stored in memory 31.

[0020] 2 shows an example in which each of the components of translation device 1 is realized by dedicated hardware, while Fig. 3 shows an example in which translation device 1 is realized by software, firmware, etc. However, this is merely an example, and some of the components in translation device 1 may be realized by dedicated hardware, and the remaining components may be realized by software, firmware, etc.

[0021] Next, the operation of the translation system shown in Fig. 1 will be described. Fig. 4 is a flowchart showing a translation method, which is a processing procedure of the translation device 1. For the sake of convenience, in the translation system shown in Fig. 1, it is assumed that the original text to be translated is Japanese, the first language is English, and the second language is Brazilian.

[0022] The original text acquisition unit 11 acquires a Japanese original text as the original text to be translated (step ST1 in FIG. 4 ). For ease of explanation, it is assumed here that the acquired Japanese original text is "After fastening the fastener again, please turn it to check." The original text acquisition unit 11 outputs the original text to be translated to each of the first translation unit 12, the correction acceptance unit 14, the second translation unit 15, and the display processing unit 16. The display processing unit 16 displays the original text to be translated output from the original text acquisition unit 11 on the display device 3.

[0023] The first translation unit 12 acquires the original Japanese text from the original text acquisition unit 11. The first translation unit 12 translates the original Japanese text acquired by the original text acquisition unit 11 into English, which is the first language (step ST2 in FIG. 4 ). Specifically, the first translation unit 12 provides the original Japanese text to the translation engine 2 and acquires an English translation from the translation engine 2. The first translation unit 12 outputs the English translation to both the back translation unit 13 and the display processing unit 16. The display processing unit 16 displays the English translation output from the first translation unit 12 on the display device 3.

[0024] The back translation unit 13 obtains the English translation from the first translation unit 12. The back translation unit 13 back-translates the translation by the first translation unit 12 (step ST3 in FIG. 4 ). Specifically, the back translation unit 13 provides the English translation to the translation engine 2 and obtains the back-translated text from the translation engine 2. The back translation unit 13 outputs the back-translated text to the display processing unit 16. When the English translation of the original text is provided to the translation engine 2, the translation engine 2 may output, for example, "Please reattach the fastener and turn it to check." This back-translated text may be interpreted as implying that the fastener is being reattached, which differs from the nuance of the original text. In other words, the original text needs to be corrected and translated again. The display processing unit 16 displays the back-translated text output from the correction receiving unit 14 on the display device 3 (step ST4 in FIG. 4 ).

[0025] The correction receiving unit 14 acquires the original Japanese text from the original text acquisition unit 11. The correction receiving unit 14 is realized by, for example, a man-machine interface, and if a user who has checked the back-translated text recognizes a difference in nuance between the original text and the back-translated text, the user can correct the original Japanese text by operating the correction receiving unit 14.

[0026] When the user performs an operation to correct the original Japanese text (step ST5 in FIG. 4 : YES), the correction receiving unit 14 accepts the correction of the original text (step ST6 in FIG. 4 ) and outputs the corrected original text to the first translation unit 12. Here, for the sake of convenience, it is assumed that the original text has been corrected to "Please make sure to turn the fastener again after installing it and check it thoroughly." If the user does not perform an operation to correct the original Japanese text (step ST5 in FIG. 4 : NO), the correction receiving unit 14 does not accept the correction of the original text.

[0027] When the corrected original text is output from the correction receiving unit 14, the first translation unit 12 acquires the corrected original text. The first translation unit 12 provides the corrected original text to the translation engine 2 and acquires an English translation from the translation engine 2. The first translation unit 12 outputs the English translation to both the back translation unit 13 and the display processing unit 16.

[0028] The back translation unit 13 obtains the English translation from the first translation unit 12. The back translation unit 13 provides the English translation to the translation engine 2 and obtains the back-translated text from the translation engine 2. The back translation unit 13 outputs the back-translated text to the display processing unit 16. When the English translation of the corrected original text is provided to the translation engine 2, the translation engine 2 may output a back-translated text such as, "After re-installing, be sure to turn the fastener again and check thoroughly." The nuance of this back-translated text matches the nuance of the original text, so there is no need to re-correct the original text. The display processing unit 16 displays the back-translated text output from the correction receiving unit 14 on the display device 3 (step ST4 in FIG. 4 ).

[0029] If the user, after checking the back-translated text, recognizes the difference in nuance between the corrected original text and the back-translated text, the user can correct the Japanese original text by operating the correction accepting unit 14. If the user performs an operation to further correct the corrected original text (step ST5 in FIG. 4: YES), the correction accepting unit 14 accepts the correction of the original text (step ST6 in FIG. 4) and outputs the corrected original text to the first translation unit 12. If the user does not perform an operation to further correct the corrected original text (step ST5 in FIG. 4: NO), the correction accepting unit 14 does not accept the correction of the original text. If the original text has been corrected one or more times, the correction accepting unit 14 outputs the most recently corrected original text to the second translation unit 15.

[0030] The second translation unit 15 acquires either the original text most recently corrected by the correction receiving unit 14 or the original Japanese text acquired by the original text acquisition unit 11. The second translation unit 15 translates either of the acquired original texts into Brazilian, which is the second language (step ST7 in FIG. 4 ). Specifically, the second translation unit 15 provides either of the acquired original texts to the translation engine 2 and acquires a Brazilian translation from the translation engine 2. The second translation unit 15 outputs the translation in the second language to the display processing unit 16.

[0031] When the Japanese original text acquired by the original text acquisition unit 11 is given to the translation engine 2, the translation engine 2 may output a Brazilian translation such as, for example, "I repeat, after installation, please be sure to undo the zipper and check." The nuance of this Brazilian translation matches the nuance of the original text, so there is no need to re-edit the original text.

[0032] The display processing unit 16 causes the Brazilian translation output from the second translation unit 15 to be displayed on the display device 3 .

[0033] In the first embodiment described above, translation device 1 is configured to include original text acquisition unit 11 that acquires an original text to be translated, first translation unit 12 that translates the original text acquired by original text acquisition unit 11 into a first language, back translation unit 13 that back-translates the translation by first translation unit 12, display processing unit 16 that displays the back-translation by back translation unit 13 on display device 3, and correction receiving unit 14 that accepts corrections to the original text after the back-translation is displayed by display processing unit 16. Translation device 1 also includes second translation unit 15 that, when corrections to the original text are accepted by correction accepting unit 14, translates the corrected original text accepted by correction accepting unit 14 into a second language. Thus, translation device 1 can translate an original text to be translated into multiple languages ​​and can reduce the time required for translation into multiple languages. The reason why the time required for translation can be reduced in this way is that after the display processing unit 16 displays the translated text, the correction receiving unit 14 receives corrections to the original text, and the second translation unit 15 translates the corrected original text received by the correction receiving unit 14 into the second language, thereby enabling the translation into the second language to reflect the results of the translation into the first language. For example, if the original text is written in the user's native language, the original text may contain a mixture of colloquial and written expressions, resulting in a sentence that is understandable to a native speaker but has an ambiguous grammatical structure. For this reason, it is generally considered difficult to translate the original text into a correct translation in one translation run, and the original text may need to be corrected. Since translation device 1 translates an original text into a first language, displays the back-translated text, allows the user to confirm and correct the original text, and then translates the text into a second language using the corrected original text, translation into the second language can be performed using the corrected original text that is already easy to translate, making it possible to obtain a translation with higher translation accuracy in a shorter time than before. Also, even if the similarity between the grammar in the first language and the grammar in the second language is higher than the similarity between the grammar in the language used in the original text and the grammar in the first language, translation device 1 translates the original text into the second language using the back-translated text that the user has confirmed and corrected, making it possible to obtain a translation with higher translation accuracy in a shorter time than before.

[0034] 1, the back translation unit 13 back-translates the English translation by the first translation unit 12. The back translation unit 13 may also back-translate the Brazilian translation by the second translation unit 15. In this case, the display processing unit 16 may display the back-translated Brazilian translation on the display device 3, and then the correction receiving unit 14 may receive corrections to the original text.

[0035] Second Embodiment In a second embodiment, a translation device 1 will be described in which a second translation unit 17 translates either the corrected original text received by the correction receiving unit 14 or the original text acquired by the original text acquisition unit 11 into one or more languages ​​different from each of the first language and the second language.

[0036] FIG. 5 is a configuration diagram showing a translation system including a translation device 1 according to embodiment 2. In FIG. 5, the same reference numerals as those in FIG. 1 indicate the same or corresponding parts, and therefore detailed description thereof will be omitted. FIG. 6 is a hardware configuration diagram showing the hardware of the translation device 1 according to embodiment 2. In FIG. 6, the same reference numerals as those in FIG. 2 indicate the same or corresponding parts, and therefore detailed description thereof will be omitted. The translation system shown in FIG. 5 includes a translation device 1, a translation engine 2, and a display device 3. The translation device 1 shown in FIG. 5 includes an original text acquisition unit 11, a first translation unit 12, a back translation unit 13, a correction acceptance unit 14, a second translation unit 17, and a display processing unit 16.

[0037] The second translation unit 17 is realized by, for example, the second translation circuit 27 shown in FIG. 6 . If the correction receiving unit 14 has accepted a correction, the second translation unit 17 acquires the corrected original text from the correction receiving unit 14. If the correction receiving unit 14 has not accepted a correction, the second translation unit 17 acquires the Japanese original text from the original text acquisition unit 11. If the correction receiving unit 14 has accepted a correction, the second translation unit 17 translates the corrected original text accepted by the correction receiving unit 14 into the second language and also translates the corrected original text into one or more languages ​​different from each of the first language and the second language. If the correction receiving unit 14 has not accepted a correction, the second translation unit 17 translates the original text acquired by the original text acquisition unit 11 into the second language and also translates the original text into one or more languages ​​different from each of the first language and the second language. Specifically, the second translation unit 17 provides the translation engine 2 with either the corrected original text received by the correction receiving unit 14 or the original text acquired by the original text acquisition unit 11, and acquires a translation in the second language and translations in one or more languages ​​different from each of the first language and the second language from the translation engine 2. The second translation unit 17 outputs the translation in the second language and the translations in one or more languages ​​different from each of the first language and the second language to the display processing unit 16.

[0038] 5, it is assumed that each of the components of the translation device 1, namely, the original text acquisition unit 11, the first translation unit 12, the back translation unit 13, the correction acceptance unit 14, the second translation unit 17, and the display processing unit 16, is realized by dedicated hardware as shown in FIG. 6. That is, it is assumed that the translation device 1 is realized by an original text acquisition circuit 21, a first translation circuit 22, a back translation circuit 23, a correction acceptance circuit 24, a second translation circuit 27, and a display processing circuit 26. Each of the original text acquisition circuit 21, the first translation circuit 22, the back translation circuit 23, the correction acceptance circuit 24, the second translation circuit 27, and the display processing circuit 26 may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

[0039] The components of translation device 1 are not limited to those realized by dedicated hardware, and translation device 1 may be realized by software, firmware, or a combination of software and firmware. When translation device 1 is realized by software, firmware, or the like, programs for causing a computer to execute the respective processing procedures of original text acquisition unit 11, first translation unit 12, back translation unit 13, correction acceptance unit 14, second translation unit 17, and display processing unit 16 are stored in memory 31. Then, a processor 32 of the computer executes the programs stored in memory 31.

[0040] 6 shows an example in which each of the components of translation device 1 is realized by dedicated hardware, while Fig. 3 shows an example in which translation device 1 is realized by software, firmware, etc. However, this is merely an example, and some of the components in translation device 1 may be realized by dedicated hardware, and the remaining components may be realized by software, firmware, etc.

[0041] Next, the operation of the translation system shown in FIG. 5 will be described. If the correction receiving unit 14 has accepted a correction, the second translation unit 17 acquires the corrected original text from the correction receiving unit 14. If the correction receiving unit 14 has corrected the original text one or more times, the second translation unit 17 acquires the original text most recently corrected by the correction receiving unit 14 as the corrected original text. If the correction receiving unit 14 has not accepted a correction, the second translation unit 17 acquires the Japanese original text from the original text acquisition unit 11. If the correction receiving unit 14 has accepted a correction, the second translation unit 17 translates the corrected original text accepted by the correction receiving unit 14 into a second language, similar to the second translation unit 15 shown in FIG. 1. Furthermore, the second translation unit 17 translates the corrected original text accepted by the correction receiving unit 14 into one or more languages ​​different from each of the first language and the second language. The one or more languages ​​different from each of the first language and the second language may be, for example, Spanish, German, Italian, Chinese, Korean, or Tagalog.

[0042] If no correction has been accepted by the correction accepting unit 14, the second translation unit 17 translates the original text acquired by the original text acquiring unit 11 into the second language, similar to the second translation unit 15 shown in Fig. 1. The second translation unit 17 also translates the original text acquired by the original text acquiring unit 11 into one or more languages ​​different from each of the first language and the second language. The second translation unit 17 outputs the translation in the second language and the translation in one or more languages ​​different from each of the first language and the second language to the display processing unit 16.

[0043] The display processing unit 16 displays the original text to be translated, which is output from the original text acquisition unit 11, on the display device 3. The display processing unit 16 displays the English translation, which is output from the first translation unit 12, on the display device 3. The display processing unit 16 displays the back-translation, which is output from the back translation unit 13, on the display device 3. The display processing unit 16 displays the Brazilian translation, which is output from the second translation unit 15, on the display device 3. The display processing unit 16 also displays the translations, in one or more languages ​​different from each of the first language and the second language, which are output from the second translation unit 15, on the display device 3.

[0044] In the second embodiment described above, the translation device 1 is configured so that the second translation unit 17 translates either the corrected original text received by the correction receiving unit 14 or the original text acquired by the original text acquisition unit 11 into the second language, and also translates either the corrected original text received by the correction receiving unit 14 or the original text acquired by the original text acquisition unit 11 into one or more languages ​​different from the first language and the second language. Therefore, the translation device 1 can reduce mistranslations when translating an original text to be translated into multiple languages.

[0045] In addition, the present disclosure allows for free combination of the respective embodiments, modification of any of the components of the respective embodiments, or omission of any of the components of the respective embodiments.
