Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine translation device for translating between different languages using a computer.

[0002]

2. Description of the Related Art In recent years, research and development of machine translation devices have been actively conducted. In this machine translation device, for example, an original sentence is translated based on a machine translation dictionary and grammatical rules that differ depending on the combination of the source language and the translated language.

In this machine translation device, for example, a dictionary for each field is prepared in addition to the basic dictionary so that a dictionary suitable for a sentence to be translated can be selected. Further, in this machine translation device, the dictionary is changed by appropriately adding a translation word to the dictionary or changing a translation word of the dictionary so that more appropriate translation is performed.

[0004]

However, since the sentence translated by the conventional machine translation device does not have information such as which dictionary was used and when it was translated, the dictionary of addition of translated words, translation of translated words, etc. When I made a change, I had no way to find out which sentence should reflect the dictionary change, that is, which sentence needed to be retranslated. Therefore, the conventional machine translation device has a problem that it is difficult to automatically reflect the contents of the dictionary change in the translated sentence, and it is difficult to keep the translated words in the translated sentence uniform.

SUMMARY OF THE INVENTION An object of the present invention is to provide a machine translation device capable of automatically reflecting the contents of dictionary changes in a translated sentence.

[0006]

A machine translation apparatus according to a first aspect of the present invention includes an input means for inputting an original sentence, a first translation instruction including information of a range to be translated and a dictionary to be used, and the input means. The range of actual translation and the information of the used dictionary based on the translation history including the information of the used dictionary and the date and time of translation of the input original sentence in the past and the first translation instruction input by the input means are displayed. Second translation instruction creating means for creating a second translation instruction including
A translation means for translating the original text input by the input means based on the second translation instruction created by the second translation instruction creation means, and a translation history for the original text translated by the translation means are created or updated. It is provided with a translation history creating and updating means.

In this machine translation apparatus, the original sentence and the first translation instruction are input by the input means, and the translation history and the first translation instruction for the input original sentence are input by the second translation instruction creating means.
A second translation instruction is created based on this translation instruction, and the original text is translated by the translation means based on this second translation instruction. Then, the translation history creating / updating means creates or updates the translation history of the translated original sentence.

According to another aspect of the machine translation apparatus of the present invention, an input means for inputting an original sentence and a first translation instruction including information of a range to be translated and a dictionary to be used, and an original sentence input by this input means are past. And a judgment means for judging whether or not there is a translation history including information on a dictionary used for translation and a translation date and time, and when the judgment means judges that there is no translation history, the first translation instruction is actually translated. The second translation instruction including information on the range and the dictionary used, and when the determination unit determines that there is a translation history, the translation history, the first translation instruction, the date and time of the dictionary update, and the date and time of translation are used in advance. Second translation instruction creating means for creating a second translation instruction according to a set rule, and input means based on the second translation instruction created by the second translation instruction creating means. And translation means for translating an input original sentence, in which a translation history creation updating means for creating or updating the translation history of original sentence translated by the translation means.

In this machine translation apparatus, the input means inputs the original sentence and the first translation instruction, and the determination means determines whether or not there is a translation history for the input original sentence.
When the second translation instruction creating means determines that the translation history does not exist by the determining means, the first translation instruction becomes the second translation instruction, and the determination means determines that the translation history exists. A second translation instruction is created according to a predetermined rule from the translation history, the first translation instruction, the update date and time of the dictionary, and the translation date and time information. Then, the original sentence is translated by the translation means based on the second translation instruction. Further, the translation history creating / updating means creates or updates the translation history of the translated original sentence.

A machine translation apparatus according to a third aspect of the present invention is the machine translation apparatus according to the second aspect, wherein the second translation instruction creating means is:
When the determination means determines that there is a translation history, the portion that has not been translated using the dictionary after the last update date and time of the used dictionary indicated by the first translation instruction is translated in the second translation instruction. It is a range.

In the ROM 13, the translation program 21,
Dictionary 22, grammar rule 23 and translation control program 25
Is stored. The translation program 21 translates the original sentence using the dictionary 22 and the grammar rules 23. Dictionary 2
2 and the grammar rule 23 differ depending on the combination of the source language and the translated language. As the dictionary 22, the basic dictionary O-DIC and the dictionary A-DIC, B-DIC for each field are used.
Etc. A rewritable ROM is used as the ROM 13, and the dictionary 22 can be updated.

FIG. 1 is a functional block diagram showing the functions of the machine translation device realized by the configuration shown in FIG. As shown in this figure, the machine translation device has input means 31 for inputting an input text and a first translation instruction indicating a range to be translated, a dictionary to be used, etc., and an original text of the input text input by this input means 31. Is provided with a translation history presence / absence determining means 32 for determining the presence / absence of a translation history including information on a dictionary used at the time of translation and translation date and time. It should be noted that the input text in the present embodiment is assumed to consist of only the original sentence if the original sentence has not been translated in the past, and to consist of the original sentence, the translated sentence, and the translation history if the original sentence has been translated in the past. .

The machine translation apparatus further includes a second translation instruction including the range of the actual translation and the information of the dictionary to be used for the first translation instruction when the translation history presence / absence determining unit 32 determines that there is no translation history. When the translation history presence / absence determining unit 32 determines that there is a translation history, the second translation instruction is made according to a predetermined rule from the information such as the translation history, the first translation instruction, the dictionary update date and time, and the translation date and time. A second translation instruction creating means 33 for creating the text and a translation means 34 for translating the original text of the input text based on the second translation instruction created by the second translation instruction creating means 33.

The machine translation apparatus further includes a translation history creating / updating unit 35 for creating or updating a translation history of the input text translated by the translation unit 34, and a translated sentence of the input text, which is translated by the translation unit 34 this time. A translation result including a translation part replacement unit 36 that replaces the translated part with a new translation sentence, a translation history created or updated by the translation history creating and updating unit 35, and a translation sentence in which the translation part is replaced by the translation part replacement unit 36. And an output means 37 for outputting

The translation means 34 in FIG. 1 has the configuration shown in FIG. 2, the translation program 21, the dictionary 22 and the grammar rules 23.
Others are implemented by the configuration shown in FIG. 2 and the translation control program 25.

Next, the operation of this embodiment will be described with reference to FIGS. FIG. 3 is a flowchart showing the operation of this embodiment.

As shown in FIG. 3, in the present embodiment, first, in step (hereinafter referred to as S) 101, the user inputs the input text and the first translation instruction by the input means 31. The input text and the first translation instruction are stored in the RAM 14. Here, the input text is the external storage device 19
Although it may be called from the file inside, when executing the operation of FIG. 3 after updating the dictionary by looking at the translation result of a certain original sentence in the middle of other processing, it is already stored in the RAM 14. There are also cases.

Here, the first translation instruction is "sentence numbers 1 to 4 of the input text having the text name" TEXT1 "are stored in the dictionary A.
-Translate using DIC and O-DIC. "

Next, in S102, the translation history presence / absence determining means 32 determines whether or not the translation history of the input text exists. If there is no translation history (“N”), the second translation instruction creating means 33 sets the first translation instruction as the second translation instruction in S103, and the process proceeds to S105. On the other hand, if there is a translation history (“Y”), in S104, the second translation instruction creating means 3
3, the second translation instruction is created according to a predetermined rule from the information such as the translation history, the first translation instruction, the update date and time of the dictionary, the translation date and time, and the process proceeds to S105.

FIG. 4 is an explanatory diagram showing an example of the translation history. As shown in this figure, the translation history includes text name information 41, sentence number information 42, information 43 on the combination of used dictionaries for each sentence number, and information 44 on the final translation date and time by the combination of the used dictionaries. Is included. In this example, for example, for the sentence number “1”, the dictionaries O-DIC and BD
Translated at 13:00 on March 15, 1990 using IC, and using dictionary O-DIC and A-DIC 1990
Translated on August 8, 14:00.

When there is a translation history, the rule for the second translation instruction creating means 33 to create the second translation instruction is, for example, that the dictionary is used after the last update date and time of the used dictionary indicated by the first translation instruction. All the untranslated parts are set as the translation range in the second translation instruction. As shown in FIG. 5, the dictionary update date and time information is managed and stored in association with a dictionary name 51 and an update date and time 52, as shown in FIG. Also, the date and time of translation is notified by the timer clock 15.

The date and time for translation is now September 9, 1990.
It is 16:50 on the day. In the case of the example of the translation history shown in FIG. 4 and the update date and time of the dictionary shown in FIG. 5, the last update date and time of the A-DIC is June 6, 1990, 9:22, and
-The last update date and time of the DIC is June 6, 1990, 10:25, so the last translation date and time when the A-DIC was used in the translation history is not June 6, 1990, 9:22 or later, or O -If the final translation date using DIC is not after June 25, 1990, 10:25,
The sentence numbers are "3" and "4". Therefore, "translating sentence numbers" 3 "and" 4 "using A-DIC and O-DIC" is the second translation instruction here.

Next, in accordance with the second translation instruction thus created, the translation means 34 translates the original sentence in S105. Here, the sentence numbers “3” and “4” are A-DI.
Translated using C and O-DIC. Next, S1
At 06, the translation history creating / updating means 35 creates a translation history if the input text has no translation history, and updates the translation history if the input text has a translation history. FIG. 6 shows the updated translation history. Here, the final translation dates and times of the sentence numbers “3” and “4” are updated.

Next, in S107, the translated portion replacing means 36 replaces the portion of the translated sentence translated by the current translation means 34 with a new translated sentence. Here, the sentence numbers “3” and “4” are replaced with new translated sentences.
Next, in S108, the external storage device 19 stores the translation result including the translation history created or updated by the translation history creating / updating means 35 and the translation sentence in which the translation part is replaced by the translation part replacing means 36 in S108. Output to a file and exit.

As described above, according to this embodiment, the dictionary A is translated by referring to the translation history and translating only the necessary sentences.
-Changes of DIC and O-DIC can be automatically reflected in the translated text, and the translated words in the translated text can be kept uniform.

In this embodiment, the input text consists of only the original sentence if the original sentence has not been translated in the past, and consists of the original sentence, the translated sentence and the translation history if the original sentence has been translated in the past. The original text, the translated text,
If the correspondence relationship of the translation history is managed, the input text may be the original text only. In this case, the translated sentence and the translation history are stored in a file in the external storage device 19,
Try to call or update when needed.

[0030]

As described above, according to the present invention, the range of actual translation and the dictionary to be used are determined by referring to the dictionary used in the past translation of the original sentence and the translation history including the information of the translation date and time. Since it is decided, there is an effect that the contents of the dictionary change can be automatically reflected in the translated sentence.
