Abstract

PURPOSE: To display another equivalent independently of the delimiter unit of the original in the process of translation, and in addition, to designate delimiter simultaneously by only executing operation to select the equivalent. CONSTITUTION: A translation processing part 2 translates the original, and outputs a translation, the original, and bilingual information including relational information between the delimiter unit of the original executed during the process of the translation and the equivalent in the translation corresponding to it. The translation and the original are displayed on a display device 8, and when a user requests dictionary consultation in which the equivalent in that translation is designated, a dictionary consulting part 5 retrieves a dictionary 1 about all the thinkable delimiter units starting from the leading character of the delimiter unit of the original corresponding to the designated equivalent, and displays that equivalents on the display device 8. When the user selects one equivalent of them, a retranslation instructing part 6 gives delimiter instruction information to designate the original word corresponding to the selected equivalent as the delimiter unit and equivalent selection instruction information to designate the selected equivalent to the translation processing part 2 as user instruction information so as to retranslate the original.

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, such as translation from English to Japanese. In particular, a correct translation was not generated because the original text was cut off in the translation process. At this time, the present invention relates to a machine translation device capable of automatically specifying word segmentation at the same time only by performing an operation of selecting a correct translation word.

[0002]

2. Description of the Related Art The current machine translation device has a limit in translation accuracy, and it is difficult to expect the ability of a translation expert. Therefore, it is necessary to work to compensate for the incompleteness of machine translation. One of the tasks is to replace an incorrect translated word in the translated sentence obtained as a result of translation by the user with a correct translated word. To support this task, for example, Japanese Patent Laid-Open No. 4-310182.
The technique found in the publication is known.

In this technique, an original sentence and a translated sentence are displayed in a state of being cut into words, and when a user designates a word cutting unit in the original sentence, a translated word corresponding to the original word of the word cutting unit is displayed. When all the displayed words are displayed and the user selects the correct translated word from them, the translated word instruction information is generated so that the selected translated word is selected instead of the original translated word at the time of retranslation.

[0004]

This conventional technique is effective when the word segmentation process of the original sentence performed in the translation process is correct, but is not useful when the process is incorrect.
That is, for example, in a machine translation device that translates an English sentence "Andso am I."
It is assumed that the translated sentence "Therefore I am." is obtained as a result of segmenting into "d so", "am", "I", and ".". Actually, I want to get the translated sentence "And me too." However, since "And so" is processed as one word-cutting unit in the translation process, the display of another translated word is only "And so". It is impossible to replace the translated word and even display the correct translated word. In such a case, it is inconvenient because it is necessary to correct an error in word cutting by specifying the word cutting, perform retranslation, and check the translated word again. In addition, since the word cut specification is an instruction to the original text side, there is a problem that the user needs knowledge of the original word on the original text side in order to perform it.

The present invention has solved the above-mentioned conventional problems, and an object thereof is to display another translated word without being affected by the word-cutting unit of the original sentence in the translation process, and still the correct translated word. An object of the present invention is to provide a machine translation device capable of automatically specifying word breaks at the same time only by performing an operation of selecting.

[0006]

In order to achieve the above object, the present invention provides a machine translation apparatus for translating between different languages, in which a dictionary for translation and an inputted original sentence are stored in the dictionary contents and If there is user instruction information that has been input separately, the instruction information is also referred to and translated, and the translated sentence, the original sentence that is the source of the translated sentence, the word segmentation unit of the original sentence that was used in the translation process, and the corresponding unit Translation processing means for outputting parallel translation information including relational information with the translated word in the translated text, parallel translation information holding means for holding the parallel translation information output from the translation processing part, and parallel translation held by the parallel translation information holding means. A translation result output unit for displaying a translated sentence in the information on a display device, and a dictionary lookup request specifying a translated word in the translated sentence displayed on the display device by the translation result output unit, an original sentence corresponding to the designated translated word Of the word cutting unit Another translation word dictionary drawing means for searching the dictionary for all possible word cutting units starting from the initial letters and displaying the translated word on the display device, and the other translation word dictionary drawing means displayed on the display device. When one of the translated words is selected, word cutting instruction information that indicates that the original word corresponding to the selected translated word should be used as a word cutting unit, and translated word selection that indicates that the selected translated word should be used Re-translation instruction means for creating instruction information and user instruction information and giving it to the translation processing means to re-translate the original sentence in the parallel translation information holding means.

In the above construction, the separate word dictionary lookup means processes only the translated words specified by the user, but the translated words in the translated text displayed on the display device without waiting for the user's designation. You may make it perform the same process as the above. In addition, the original sentence is displayed in addition to the translated sentence, and a separate word dictionary is provided for the word cutting unit including the translated word specified by the user in the original sentence, or for each word cutting unit in the original sentence without waiting for such specification. The pulling means may perform the same processing as described above.

[0008]

In the machine translation apparatus of the present invention, the translation processing means translates the input original sentence by also referring to the contents of the dictionary for translation and the separately input user instruction information, if any. , Translated information, the original sentence that is the source of the translated sentence, the word segmentation unit of the original sentence that was used in the process of translation, and the relation information of the translated word in the translated sentence corresponding to this unit are output, and the translated information is retained. The means holds the output parallel translation information, and the translation result output means displays the translated text in the parallel translation information on the display device. Then, when the dictionary translation request is made by the translation word dictionary lookup means that designates the translation word in the translation displayed on the display device, it starts from the first character of the word segmentation unit of the original sentence corresponding to the specified translation word, and all conceivable When the dictionary is searched for the word segmentation unit and the translated word is displayed on the display device, and the retranslation instructing means selects one of the translated words displayed on the display device by the another translated word dictionary drawing means, The word cutting instruction information for instructing that the original word corresponding to the selected translation word should be used as the word cutting unit and the translation word selection instruction information for instructing that the selected translation word should be used are created as user instruction information. To the translation processing means to retranslate the original text in the parallel translation information holding means.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings.

Referring to FIG. 1, an embodiment of a machine translation apparatus of the present invention is a machine translation apparatus for translating English into Japanese, which includes a dictionary 1, a translation processing unit 2, and a parallel translation information holding unit 3.
And a translation result output unit 4, another translation word dictionary drawing unit 5, a retranslation instruction unit 6, an instruction information holding unit 7, a display device 8, and a keyboard 9. The present invention can be applied to other machine translation devices between different original languages, such as translating Japanese into English.

The dictionary 1 is a dictionary for translation, and holds dictionary contents such as translated words, parts of speech, and examples for each headword in the original language, English. The instruction information holding unit 7 is a translation processing unit 2.
Is a part for holding the user instruction information for. In the present embodiment, the instruction information holding unit 7 is configured to hold the word cutting instruction information and the translated word selection instruction information at the time of retranslation described later.

FIG. 2 is a flow chart showing an example of the operation of the machine translation device shown in FIG. When the user inputs an English original sentence from the keyboard 9, the translation processing unit 2 inputs this original sentence (S1) and performs translation processing (S2). In this translation processing, morphological analysis, syntactic analysis, and sentence generation for the original sentence are performed using the dictionary contents of the dictionary 1 and the analysis rules incorporated in the translation processing unit 2. At this time, the translation processing unit 2 refers to the instruction information holding unit 7, and if the word cutting instruction information is present, performs the word cutting processing as instructed by this information, and the translated word selection instruction information is sent. If so, use the translation as indicated by the information. If there is no such word cut instruction information or translated word selection instruction information, word cut processing and translated word selection are executed according to the analysis rule. Since the user instruction information does not exist during the first translation when the original sentence is input from the keyboard 9, the translation processing unit 2 executes word segmentation processing and translation word selection according to the analysis rule. When the translation processing unit 2 completes the translation process of the original sentence, the relationship between the generated translated sentence, the original original sentence, the word segmentation unit of the original sentence performed in the process of the translation process, and the translated word in the translated sentence corresponding to the unit. The parallel translation information including the information is stored in the parallel translation information holding unit 3.

When the bilingual translation information is stored in the bilingual translation information holding unit 3, the translation result output unit 4 displays the translated sentence in the bilingual translation information on the display device 8 and presents it to the user (S3). At this time, in this embodiment, the original text is also displayed on the display device 8.

When the user who sees the translated sentence displayed on the display device 8 judges that a certain translated word is inappropriate and selects the translated word and requests the keyboard 9 to display another translated word, this request is issued. It is input to the extra-translation word dictionary drawing unit 5 and detected here (S4), and the extra-translation word dictionary drawing unit 5 refers to the bilingual translation information in the bilingual translation information holding unit 3 and corresponds to the translation word designated by the user. The word segmentation unit of the original sentence is recognized, the dictionary 1 is searched for dictionary contents having all possible word segmentation units as headwords starting from the first character, and the obtained translated word is displayed on the display device 8 (S6). ).

As another embodiment, the separate word dictionary lookup unit 5 determines the word segmentation unit of the original sentence corresponding to each translated word in the translated sentence displayed on the display device 8 without waiting for the user's designation. You may make it perform the same process. In addition, whether to perform the same processing as above for the word cutting unit including the original word specified by the user in the displayed original text, or
Alternatively, the processing similar to the above may be performed for all word segmentation units in the original sentence without waiting for such designation.

Next, when the user selects one of the translation word candidates displayed on the display device 8 from the keyboard 9 (YES in S7), the another translation word dictionary drawing section 5 replaces the original translation word with the original translation word. The selection information including the selected translated word and the corresponding original word heading (original word heading when the selected translated word is looked up in the dictionary) is passed to the re-translation instruction unit 6, and the re-translation instruction unit 6 divides the word into words. Whether or not there is a change is determined by comparing the original word heading passed from the separate translation word dictionary drawing unit 5 with the original word of the original translated word in the bilingual translation information (S9).
Then, when the word cut unit is changed (YE in S9).
S) That is, when the original word heading and the original word of the original translation do not match, the new source word heading is created as word cutting unit information and set in the instruction information holding unit 7 ( S10), then, for the original word, translated word selection instruction information indicating that the selected translated word should be used is created and set in the instruction information holding unit 7 (S11), and the original sentence is retrieved from the parallel translation information holding unit 3. And transmits it to the translation processing unit 2 to instruct retranslation. As a result, the translation processing unit 2 translates the original original sentence again (S12). At this time, since the word cutting instruction information and the translation word selection instruction information are set in the instruction information holding unit 7, the translation processing unit 2 advances the translation process with reference to them.

On the other hand, if the retranslation instructing section 6 determines in step S9 that the word segmentation unit has not been changed, that is, if the original word headline and the original word of the original translated word match, step S10 is skipped. Therefore, only the translated word selection instruction information is created and set in the instruction information holding unit 7.

When the translated text is displayed, the user presses the keyboard 9
When the end instruction is input from (YES in S5) and when the end instruction is input without selecting a translated word when another translated word is displayed (YES in S8), the machine translation apparatus ends the translation process of the original sentence. At this time, the user instruction information in the instruction information holding unit 7 is cleared.

Next, the operation of the machine translation apparatus of this embodiment will be described by taking a concrete English sentence as an example. For example, "And
so am I. Will be taken up.

When the user inputs the above-mentioned English sentence from the keyboard 9, the translation processing unit 2 inputs this English sentence (S1),
A translation process is performed (S2). In this translation processing, since the user instruction information does not exist in the instruction information holding unit 7, the translation processing unit 2 executes translation processing such as word segmentation processing and translation word selection according to the dictionary content of the dictionary 1 and the analysis rule. Now, when the above English sentence is cut into words "And so", "am", "I", and ".", And "so" is selected as the translation word of "Andso", for example, as shown in FIG. Original text,
The parallel translation information including the original word position, the translated sentence, the translated word position, and the parallel translation is generated and held in the parallel translation information holding unit 3, and the original sentence and the translated sentence are displayed on the display device 8 (S
3).

In the case of the present embodiment, the source word position, the target word position, and the bilingual translation in FIG. 3 indicate the relationship between the word segmentation unit of the source sentence performed in the translation process and the target word in the source sentence corresponding to that unit. Becomes The original word position indicates the byte position of each word cut in the original sentence. In this case, "And s
Since the words "o", "am", "I", and "." are cut off, it is indicated by the original word position that each starts from the 0th, 7th, 10th, and 11th bytes in the original sentence. The translated word position also stores the translated word start position in the translated sentence, like the original word position. The bilingual translation stores the position of the original word, which is the dictionary heading for each translated word. That is, the original word for "so" is "And s
Since the original words of "o" and "I" correspond to "I", their original word positions 0 and 10 are set. The translation "ga"
And "." Are not the translated words obtained as a result of looking up the dictionary, so that there is no corresponding original word position and it is -1.

When the user who sees the translated sentence displayed on the display device 8 selects the translated word "according to" in the translated sentence and requests the display of another translated word, the translated word dictionary drawing unit 5 holds the translated information. By referring to the bilingual information in Part 3, the word segmentation unit "And so" of the original sentence corresponding to the translated word "according to" specified by the user is recognized, and all the conceivable starting from the first character "A" are recognized. Dictionary 1 for word cutting unit
Is displayed and its translation is displayed on the display device 8 (S6).
In this case, all possible word-cutting units are "An
d ”,“ And so ”,“ And so am ”,
"And so am I", "And so am
I. Therefore, the dictionary 1 is searched with these as the original word headings. The leading A is processed as a lower case a.

FIG. 4 shows an example of the translated words retrieved. In this case, there are original word headings matching "and" and "andso" in the dictionary 1, and "and so am", "An"
Since there was no original word heading matching "dso am I" and "And so am I.", "and"
And translated words corresponding to "and so" are displayed.
In the conventional device, only the translated word for "and so" is displayed, but in this embodiment, the translated word for "and" is also displayed. The corresponding original word headings are shown in parentheses.

Next, when the user selects "and" from the candidate translations shown in FIG. 4, the original translation "according to" is displayed.
The selected translated word "and" and the corresponding original word heading "and" are passed to the re-translation instruction unit 6, and the re-translation instruction unit 6 changes the original word heading "and" to the original translated word "accordingly". Since it is different from the original word "And so" of, it is determined that the word cutting unit has been changed (N in S9
O), word cut instruction information indicating that the new original word heading "and" should be used as a word cut unit, and a translated word selection instruction indicating that the selected translated word "and" should be used for the original word "and" Information is created and set in the instruction information holding unit 7 (S10, S11).

FIG. 5 shows an example of the word cutting instruction information and the translated word selection instruction information. The word segmentation instruction information “0-3” has a length of 3 bytes from the 0th byte of the original sentence (that is, “And”) set to 1
It is instructed that the word should be cut out as one word cutting unit, and the translation word selection instruction information "0-" and "" indicates that "and" should be selected as the translation word of the word from the 0th byte (that is, "And"). Instructing.

When the retranslation instruction unit 6 completes the setting of the translation word selection instruction information and the word segmentation instruction information, the parallel translation information holding unit 3
The original sentence "And so am I." is extracted from the above and transmitted to the translation processing unit 2 to instruct retranslation (S12). As a result, the translation processing unit 2 refers to the instruction information held in the instruction information holding unit 7 and retranslates it. As a result, "An
The dictionary contents having the words "d", "so", "am", "I", "." and the translation "and" for "And" are selected to proceed the processing. This allows
The translation changes from "So I am." To "And I am."

[0027]

As described above, according to the present invention, since all possible word-cutting units starting from the first character of the word-cutting unit processed in the translation process of the original sentence are dictionary-displayed, the translated word is displayed. , A translation word can be displayed without being affected by the word break unit of the original sentence in the translation process, and a word indicating that the original word corresponding to the translated word selected by the user should be the word break unit. Since the cutting instruction information is automatically created and re-translated, the word cutting can be automatically specified at the same time only by selecting the correct translation word. As a result, there is no need to separately specify word segmentation, which is tedious in operation and difficult to understand, and there is an effect that work efficiency is improved.
