Abstract

PURPOSE:To easily confirm both a sentence of a translation and a text of the original text at a time by displaying the sentence of the original text nearby the display position of the indicated sentence of the translation only at a request to display the original text. CONSTITUTION:When an English sentence is inputted from an original text input means 1, a translating means 3 performs sentence analysis and sentence generation processing by using a dictionary 2 and outputs the respective sentences of the original text and its translation in pairs to a translation information storage means 4. The translation information storage means 4 give a sentence number to each sentence of the original text and its translation each time they are outputted from the translating means 3 and stores them inside. A user when confirming the original text so as to correct the translation indicates the translation whose original text is to be confirmed and makes an original text confirmation request. An original text display control part 54 recognizes the sentence number of the sentence of the translation, reads the sentence of the original text out of the translation information storage means 4 and stores it in an original text buffer 55, and specifies the size and position of a window for original text display and sends a display request to a display/input control part 56, thereby displaying the sentence on the screen of a CRT 7.

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 sentences, and more particularly to a machine translation device devised in a method of displaying an original sentence corresponding to a translated sentence.

[0002]

2. Description of the Related Art Generally, a machine translation device cannot always obtain a correct translated sentence because of its translation accuracy.
Therefore, it is often necessary to manually correct the translated text after translation. To correct the translation after translation,
Since it is necessary to refer to the original sentence, many conventional machine translation devices display the original sentence at the same time when the translated sentence is displayed on the display device. That is, the translation result is displayed on the display device in a bilingual format.

However, in such a bilingual display, since the space for displaying translated texts is reduced due to the display space, many translated texts cannot be displayed within one screen, and the contents of the document can be understood. However, it is not convenient for reading. In addition, since the original text is always displayed, the display content is complicated, and in parallel display, the translated text and the original text are often separated by one sentence and displayed in correspondence with each other. Therefore, the flow of the text is divided and difficult to read. There are also inconveniences.

Therefore, as disclosed in, for example, Japanese Patent Laid-Open No. 64-15870, in addition to the parallel translation mode in which the original sentence and the translated sentence are displayed in correspondence with each other, the translated sentence mode in which only the translated sentence is displayed and the original sentence mode in which only the original sentence is displayed. A machine translation device has been proposed in which three display modes such as and can be arbitrarily selected.

[0005]

In this conventional machine translation apparatus, since the translated text can be displayed using the entire screen of the display device by selecting the translated text mode, many translated texts can be displayed at one time. It is convenient to read while understanding the contents of the document. Also, it is convenient to select the parallel translation mode or the original sentence mode because the contents of the original sentence can be referred to.

However, when a sentence whose meaning is not well understood appears while reading the translated sentence displayed in the translated sentence mode, if the original sentence mode is selected to refer to the original sentence, the original sentence can be referred to but the translated sentence is It disappears from the screen. Therefore, in order to confirm the translated text again, it is necessary to switch to the translated text mode again. Then, to refer to the original sentence again, it is necessary to change to the original sentence mode again, and it becomes necessary to alternately change the translated sentence mode and the original sentence mode.

On the other hand, if the parallel translation mode is selected, it is convenient because both the translated text and the original text can be confirmed at one time. However, if the translation mode is changed to the parallel translation mode, the translated text is displayed on the entire screen. The screen is switched to display the translated text in half and the original text in the other half, so the display position of the translated text that you are currently interested in will change, and you will need to revisit the entire document to find the translated text that you are interested in. There is. Further, in the parallel translation mode, since the display amount of the translated text is reduced to about half, the translated text part that is currently focused on may disappear from the screen in some cases. As a result, work efficiency is reduced.

The present invention has solved such a conventional problem, and its purpose is to display and use only the translated text on the screen so that it is convenient for reading while understanding the content of the document. Only when there is a request from the person to display the original sentence that indicates a certain sentence in the translated sentence, by displaying the original sentence near the display position of the designated translated sentence, there is a problem that is currently being noticed. It is an object of the present invention to provide a machine translation device capable of easily confirming both a translated sentence and its original sentence at once.

[0009]

In order to achieve the above object, the present invention provides a machine translation device having a translation means for translating an input original sentence using a dictionary to generate a translated sentence, wherein the translation means Parallel translation information storage means for storing the obtained translated text and the original text corresponding to the translated text in association with each other,
It is provided with a display device, an input device, and a display editing means. The display editing means displays the translated sentence stored in the parallel translation information storage means on the display device, and an original sentence display request indicating any sentence of the translated sentence displayed on the display device is input from the input device. The original sentence corresponding to the instructed translated sentence is read from the parallel translation information storage means and displayed near the instructed translated sentence displayed on the display device.

[0010]

In the machine translation apparatus of the present invention, the parallel translation information storage means holds the translated text obtained by the translation means and the corresponding original text in sentence units, and displays and edits when the translated text is obtained. The means first displays only the translated text stored in the parallel translation information storage means on the display device. When a user reads a translated sentence and finds a sentence whose meaning is not well understood, when a user inputs an original sentence display request instructing the sentence from the input device, the display editing means displays the original sentence corresponding to the instructed sentence. Is read from the parallel translation information storage means and displayed near the sentence of the designated translation on the display device.

[0011]

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 an English-Japanese translation apparatus in which the source language is English and the target language is Japanese, and a source text input means 1, a dictionary 2 and Translation means 3, parallel translation information storage means 4, and display editing means 5
A translated text output means 6, a CRT 7, a keyboard 8,
It is composed of a mouse 9 and. It goes without saying that the present invention can be applied to translation between other arbitrary languages such as Japanese-English translation.

The original sentence input means 1 is a means for inputting an original sentence to be translated. It is generally composed of a CRT and a keyboard, but may be a device for reading a document file output by an OCR input device or another system that handles documents.

The dictionary 2 is a vocabulary of knowledge necessary for sentence analysis and sentence generation when translating English into Japanese, and morpheme level information for morphological analysis and morpheme generation. , Syntax level information for parsing and generating, semantic level information for semantic analysis,
Holds information about bilingual words.

The translation means 3 is means for receiving an original sentence from the original sentence input means 1 and performing a translation process. That is, the original sentence received from the original sentence input means 1 is subjected to sentence analysis of the original sentence using the dictionary 2 and internal analysis rules to generate an analysis result. A sentence is generated using the generation rule to generate a translated sentence. The translated text, which is the translation result, is sent to the parallel translation information storage means 4 in pair with the original original text.

The parallel translation information storage means 4 is means for storing the translated text obtained by the translation means 3 and the corresponding original text in pairs. FIG. 2 shows an example of parallel translation information stored in the parallel translation information storage unit 4. As shown in the figure, the parallel translation information storage means 4 of this embodiment stores an original sentence and a translated sentence in pairs on a sentence-by-sentence basis, and further assigns sentence numbers to them. This sentence number is assigned and assigned by the parallel translation information storage means 4 in order from 1, for example.

The translated text output means 6 is means for finally outputting the translated text stored in the parallel translation information storage means 4. In general, it is a printer, but a device that outputs in the form of a document file for use as an input to a CRT or another system is also used.

The display / editing means 5 is the most characteristic part of the present invention. The translated text stored in the parallel translation information storage means 4 is displayed on the CRT 7 for checking or the keyboard 8 from the user. When there is a request to display the original text by operating the mouse or the mouse 9, the corresponding original text is displayed on the CRT 7, and the translated text is edited in response to the editing operation of the translated text by the keyboard 8 or the mouse 9. It has a function to do. In this example, the display / editing means 5 comprises a translated text display / editing control section 51, a correspondence table 52, a translated text buffer 53, an original text display control section 54, an original text buffer 55, and a display / input control section 56.

The translated text buffer 53 is a buffer for temporarily holding translated texts to be displayed on the screen of the CRT 7, and is composed of areas corresponding to each row and each column of the translated text display screen of fixed size. On the other hand, the original text buffer 55 is a buffer that temporarily holds the original text to be displayed on the screen of the CRT 7. The original text held in the original text buffer 55 is displayed in a variable size original text display window as described later.

The translated text display / edit control unit 51 is a part that controls the determination and editing of the translated text to be displayed. The translated sentence display edit control unit 51 reads a translated sentence and a sentence number for one screen from the parallel translation information storage unit 4, and manages the translated sentence while managing the sentence number and the display position of the translated sentence corresponding thereto with the correspondence table 52. Displaying is enabled by storing in the buffer 53. When the screen scroll is instructed from the keyboard 8 through the display / input control unit 56, the contents of the translation buffer 53 are rewritten in accordance with the scroll direction to realize scrolling, and at the same time, the contents of the correspondence table 52 are rewritten. Furthermore, when an editing instruction such as insertion or deletion of a character is input from the keyboard 8 or the like via the display / input control unit 56, the translated text in the translated text buffer 53 is updated or deleted, and at the same time the translation information storage means 4 is stored. The original translation is also corrected, and the contents of the correspondence table 52 are rewritten.

FIG. 3 shows an example of the contents of the correspondence table 52.
As shown in the figure, the correspondence table 52 holds the sentence number and the screen display position of the translated sentence displayed on the screen of the CRT 7. Here, in the screen display position, in the present embodiment, the first character and the last character of each sentence of the translated sentence are CR.
It is represented by a row number and a column number that indicate which row and which byte of the screen of T7 is displayed.

The original text display control unit 54 is operated by the CRT 7 from the keyboard 8 or the mouse 9 through the display / input control unit 56.
When an original sentence display request indicating the display position of the sentence is input, the sentence number of the indicated translated sentence is obtained from the indicated display position and the contents of the correspondence table 52, and the original sentence of the sentence number is stored in the parallel translation information storage means. After reading the data from No. 4 and storing in the original text buffer 55, the display / input control unit 56 is requested to display the original text by designating the size and display position of the window for displaying the original text.

Here, the size and display position of the window for displaying the original text are obtained as follows in this embodiment. First, the screen display position of the last character of the translated sentence for which the display of the original sentence is requested is acquired from the correspondence table 52, and there is a predetermined M bytes (for example, half the screen horizontal size) or more space behind the last character. For example, the horizontal width of the window is the width of the space, and the vertical width is obtained from the number of characters of the original text to be displayed and the horizontal width of the window. Then, the display position is determined so that the upper left corner of the window is located immediately after the last character. On the other hand, if there is no space of M bytes or more after the last character, the horizontal width of the window is set as the maximum size, and the vertical width is obtained from the number of characters of the original sentence to be displayed and the horizontal width of the maximum size of the window. Then, the display position is determined so that the upper left corner of the window is located at the beginning of the line next to the line where the final character is located.

The display / input control unit 56 uses the translated text buffer 5
The translated text in 3 and the original text in the original text buffer 55 are actually displayed on the screen of the CRT 7, and the original text display request and various editing instructions are accepted from the keyboard 8 and the mouse 9, and the translated text display edit control unit 51 and the original text display control unit are received. It is a means for transmitting to 54.

The operation of the machine translation apparatus of this embodiment having the above structure will be described below. As an example, let us consider a case where the following English sentence is input from the original sentence input means 1. Specification of the application.The applicati
on is described in more detail in this section.Th
e appli-cation provides three functions.

When the above-mentioned English sentence is input from the original sentence input means 1, the translation means 3 uses the dictionary 2 to execute sentence analysis and sentence generation processing, and each sentence of the original sentence and its translated sentence are paired and translated information is translated. Output to the storage unit 4. Each time the translation unit 3 outputs each sentence of the original sentence and its translated sentence, the parallel translation information storage unit 4 assigns a sentence number to the sentence and accumulates it internally. As a result, in the case of the English sentence, the contents shown in FIG. 2 are accumulated in the parallel translation information storage means 4.

The translated text display edit control section 51 of the display editing means 5
When the translated texts are stored in the bilingual information storage means 4, reads sequentially. First, the sentence number 1 and its translated sentence "application specifications" are read out and stored in the beginning of the translated sentence buffer 53. From the correspondence between the translated sentence buffer 53 and the translated sentence display screen, the screen of the first letter "A" of the translated sentence is read. Display position “row = 1, column = 1” (hereinafter, “row = X, column = Y” is simply expressed as “X, Y”) and the screen display position “1,21” of the final character “sama” And the sentence number 1 as shown in FIG.
And the screen display positions “1,1” and “1,21” are registered in the correspondence table 52. Then, the sentence number 2 and its translation "The application is described in more detail in this chapter." And the sentence number 3 and its translation "The application provides three functions." Perform the same processing as. This operation is continued until the translated text buffer 53 is full or all translated texts have been processed, and then the display / input control unit 56 displays the translated text buffer 5.
Request the display of the translated text in 3.

As a result, the translated text is displayed on the screen of the CRT 7 in the form as shown in FIG. 4, for example.
That is, only the translated sentence of the parallel translation information stored in the parallel translation information storage means 4 is displayed on the screen of the CRT 7. Therefore, many translated texts can be displayed in one screen, and the translated texts are not separated one by one unlike the bilingual format, which makes the translated texts easy to read.

In the example of FIG. 4, only at most three sentences are displayed, but if there are four or more translated sentences generated, it goes without saying that they are also displayed at the same time. . For a portion that cannot be displayed on one screen because there are many translated texts, the translated text display edit control unit 51 rewrites the translated text buffer 53 to scroll the translated text screen by giving a scroll instruction from the keyboard 8 or the like. At this time, the contents of the correspondence table 52 are also updated at the same time.

Now, the user is reading through the translated text as shown in FIG. 4 to correct the translated text "The application is described in more detail in this chapter." When confirming the original sentence, the original sentence confirmation request is issued by instructing the translated sentence for which the original sentence is desired to be confirmed.

As a method of instructing the translated text for confirming the original text,
In the present embodiment, a method of placing the cursor of the mouse 9 on any character in the translated text and clicking is adopted,
The clicked display position is transmitted to the original text display control unit 54 through the display / input control unit 56, and the original text display control unit 54 is transmitted.
Recognizes the sentence number of the translated sentence displayed at the clicked display position from the clicked display position and the contents of the correspondence table 52. For example, if the character "A" at the beginning of the second line on the screen of FIG. 4 is clicked, the clicked position is "2, 1", so sentence number 2 is obtained from the content of FIG.

Next, the original sentence display control unit 54 causes the sentence "The application is described" of the original sentence corresponding to the obtained sentence number 2.
in more detail in this section. "is read from the parallel translation information storage means 4 shown in FIG. 2 and stored in the original text buffer 55, and the size and position of the window for displaying the original text is designated to the display / input control unit 56. Request display. In this case, since the display position of the final character "." Of the designated translation is "3, 7" and there is a space of 36 bytes which is more than half the screen size, the width of the window is 36. A byte and the display position of the upper left corner of the window is "3, 9". In addition, the vertical width is 2 lines based on the number of characters in the original sentence. As a result, an original text display window as shown by symbol W in FIG. 5 is opened on the screen of the CRT 7, and the contents of the original text are displayed there.

In this way, the user can confirm the content of the original sentence as necessary on the screen displaying the translated sentence. Here, if various editing instructions such as correction and deletion are given from the keyboard 8 or the like, the translated text can be corrected. That is, when the translated text display edit control unit 51 receives editing instructions such as insertion, deletion, and addition of characters from the keyboard 8 or the like through the display / input control unit 56, the translated text display edit control unit 51 updates the corresponding portion of the translated text buffer 53. At the same time, the correspondence table 52 is rewritten according to the updated contents, and the updated translated sentence is updated with the updated translated contents in the parallel translation information storage means 4.

The displayed window W for displaying the original sentence is erased by the display / input control unit 56 by inputting an erase instruction from the keyboard 8 or the like, and the screen returns to the screen for displaying only the translated sentence.

The translated text in the parallel translation information storage means 4 which has been corrected as described above can be printed out by the translated text output means 6, for example.

[0036]

As described above, according to the present invention, the following effects can be obtained.

Normally, only the translated text is displayed on the screen of the display device, so the display amount of the translated text is reduced as in the parallel translation display.
Since it is displayed on a sentence-by-sentence basis, there is no inconvenience such as division of the flow of translated sentences, and it is convenient for reading while understanding the contents of the document.

When the original sentence display request is made, the original sentence is displayed near the display position of the designated translated sentence, so that the translated sentence and the original sentence can be confirmed at the same time. In this case, since the original translated sentence is displayed at the same position and the original sentence is displayed in the vicinity of the original position, it is possible to easily confirm the translated sentence and the original sentence that are currently focused. In the conventional machine translation device in which the parallel translation mode, the original text mode, and the translation mode can be selected, there is no inconvenience such as when the translation mode is changed to the parallel translation mode, and the work efficiency is improved.
