Abstract

PURPOSE:To reduce the burden of translated sentence editing works to an operator by automatically detecting a readjusted translated sentence containing a word string which can be used as a key for uniting a literary style and the original sentence corresponding to the translated sentence and displaying the translated and original sentences on a screen together with an original sentence and its translated sentence being edited. CONSTITUTION:A word string in a translated sentence being displayed on a screen is designated by means of a word string designating means and a readjusted sentence containing the designated word string and the original sentence corresponding to the translated sentence are respectively extracted from a translated sentence storing means 5 and original sentence storing means 2 by means of an extracting means. Then a controlling means 6 displays the translated and original sentences extracted by means of the extracting means on the screen together with the translated and original sentences used for designating the word string. Therefore, the burden of translating sentence editing work to an operator can be reduced and the translated sentence editing process for uniting the literary style can be performed efficiently.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a machine translation system that inputs an original text in Japanese or the like and translates this original text into another language such as English.

(Prior Art) In recent years, systems that use computers to machine translate input original texts have been attracting attention.

In general, this machine translation system converts the input original text into words (phrases) by performing processing such as morphological analysis and syntactic analysis.
The system divides into predetermined processing units, such as, searches the translation dictionary for each processing unit, extracts the corresponding translated words (translated phrases), etc., and combines them according to predetermined translation rules to obtain the translation. It is configured.

However, in such machine translation systems, it has been difficult to reliably obtain appropriate translations, partly because semantic interpretation techniques for natural languages, for example, have not been sufficiently established.

For this reason, conventionally, a plurality of translation candidates obtained as a result of translation are presented to the user (operator), and the translation is revised using the translation candidate judged by the user to be the most appropriate.

By the way, when a translated sentence is revised using such a method, other same sentences also need to be revised in the same way in order to unify the writing style.

Therefore, if the operator has completely memorized the revised translation, there will be no problem, but if the operator's memory is vague, he or she will have to display the revised translation and check it again on the screen. .

In the case of Snake, each translation had to be displayed on the screen one by one to find the desired translation, which placed a burden on the operator and made it difficult to efficiently edit the translations to standardize the writing style. .

(Problems to be Solved by the Invention) The present invention is intended to solve the problems in conventional machine translation systems, and aims to provide revised translations that include word strings that are key to unifying writing styles, and the corresponding solutions. By automatically detecting the original text to be edited and displaying these translations and the original text on the screen together with the translation and original text currently being edited, it is possible to reduce the burden of translation editing work on the operator and efficiently unify the writing style. The aim is to provide a machine translation system that can perform translation editing processing for translation.

[Configuration of the Invention (Means for Solving the Problem) In order to achieve the above-mentioned object, the machine translation system of the present invention includes an input means for inputting an original text, an original text storage means for storing the input original text, A translation means for translating an input original text using a translation dictionary, a translation storage means for storing the translated text, a display means for displaying the translated text and the original text on a predetermined screen, and a translated text displayed on the screen. a translated text correction means for modifying the translated text as necessary; a word string specifying means for specifying a word string in the translated text displayed on the screen; and a revised translated text containing the word string specified by the word string specifying means. an extraction means for extracting the corresponding original text from the translated text storage means and the original text storage means; and a control means for displaying the translated text and the original text extracted by the extraction means on a screen together with the translated text and the original text used for specifying the word string. It is equipped with the following.

(Function) In the machine translation system of the present invention, the word string specifying means first specifies a word string in the translated text displayed on the screen, and then the extracting means extracts a revised word string containing the specified word string. The translated text and the corresponding original text are extracted from the translated text storage means and the original text storage means, respectively. And the control means
Since the translated text and original text extracted by the extraction means are displayed on the screen together with the translated text and original text used to specify the word string, the burden on the operator of editing the translated text can be reduced, and the translated text can be edited for efficient writing style standardization. It becomes possible to perform processing.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram showing the configuration of a machine translation system according to an embodiment of the present invention.

As shown in the figure, this machine translation system includes an input unit 1, such as a keyboard device, for inputting the original text to be translated, and an original text storage unit for storing the original text (Japanese text in this case) input from the input unit 1. 2, and a translation dictionary 3 that stores various kinds of knowledge information used in translation processing (a rule/irregular variation dictionary 3a, a word/idiom dictionary 3b, an analysis grammar 3c, a conversion grammar 3d, a generative grammar 3e, and a morpheme generative grammar 3f). a translation unit 4 that uses the translation dictionary 3 to translate the original text stored in the original text storage unit 2; a translated text storage unit 5 that stores sentences (in this case, English sentences) translated by the translation unit 4; An editing control unit 6 that controls the entire system including word string search processing, a display unit 7 that displays a translated text and the corresponding original text, and a display control unit 8 that controls the display of the display unit 7. Display section 7
and a printing section 9 for outputting the contents displayed on the screen as a hard copy.

FIG. 2 is a diagram showing an example of the key arrangement of the input section 1 described above.

As shown in the figure, the input unit 1 includes a translation instruction key 100, edit keys 101-106, function keys 110-118, and cursor keys 130-133, in addition to a character key 1o for inputting English and Japanese sentences. It is equipped.

FIG. 3 is a diagram showing an example of the layout on the screen of the display section 7 mentioned above.

As shown in the figure, the input original text is displayed in the original text display area 20a on the right side of the screen 2o. The translated text obtained as a result of the translation process is displayed in the translated text display area 20b on the left side of the screen 20. The upper part of the screen is an editing area 2°C for displaying information necessary for various editing processes.

Next, the flow of translation processing in this embodiment system will be explained.

FIG. 4 is a flowchart showing the flow of translation processing by the editing control unit 6.

First, translation processing in this system is started by an operator's key operation on the input unit 1.

As a result, the editing control unit 6 performs steps 401 to 405.
Whether there is any key input from input unit 1 in
Then, the system enters a monitoring state to see if a translation completion signal is input from the translation section 5, and when any key input is made, the processing corresponding to each key is performed as follows.

When the operator operates any of the function keys 110-118, the editing control unit 6 detects this in step 4.5 and executes the process corresponding to the editing key 110-118 in step 406.

Further, when the operator operates the cursor keys 130 to 133 or other control keys, the editing control unit 6 performs processing for moving the cursor and other processing corresponding to the key operation via steps 401 to 405. (Step 4o7).

Furthermore, when the operator inputs the original text by operating the character keys 10, the editing control unit 6 detects the character keys 10 in step 403 and sequentially sets the corresponding character codes in an input buffer (not shown) in the editing control unit 6. (Step 408).

Thereafter, the input original text is displayed in the original text display area 20a of the display unit 7 via the display control unit 8 (step 409).

Further, when the operator operates the translation instruction key 100 after inputting the original text of the sentence, the editing control unit 6 detects the operation of the translation instruction key 100 in step 402, and transfers the original text in the input buffer to the translation unit 4. and instructs the start of translation processing (step 410).

Note that when performing editing processing such as correction, insertion, or deletion while inputting the original text, move the cursor to the desired position using the cursor keys 130 to 133, and then press the edit keys 101 to 106, such as the insert key or the delete key. These are executed by manipulating (step 411).

Next, the flow of translation processing in the translation section 4 of this embodiment system will be explained with reference to the flowchart of FIG.

First, when an original sentence is input, morphological analysis is performed to search the rule/irregular change dictionary 3a in the translation dictionary 3 for words that have changes in the ending, etc. in the original sentence and convert them into original forms (basic forms) (step 501). .

Thereafter, English words and phrases corresponding to the prototype words constituting the input original text are retrieved by searching the word/idiom dictionary 3b (step 502).

Next, each word candidate drawn from this word/idiom dictionary 3b is sent to the syntactic analysis unit via analysis control (step 503).

As a result, a syntactic analysis of the translation candidate is performed using the analysis grammar 3C, thereby generating an English word string having a Japanese sentence structure (step 504).

Note that if the analysis fails here, the process returns to analysis control in step 503.

Next, the word string consisting of the structure of the Japanese sentence generated by the syntactic analysis is converted into the structure of the English sentence according to the conversion grammar 3d (step 505).

If the conversion process is rejected during this structural conversion,
Returning to step 504, parsing.

Next, the word order of the word string converted to the English sentence structure is generated using grammar 3.
e (step 506).

Furthermore, after this, the morpheme generation process using the morpheme generation grammar 3f is performed to correct the word endings and the like for the word string whose word order has been determined (step 507).

With the above steps, the translation process ends.

Upon completion of this translation process, a translation completion signal is output to the editing control section 6.

The subsequent operation will be explained with reference to FIG. 4 again.

When a translation completion signal is output from the translation unit 4 to the editing control unit 6, the editing control unit 6 detects this translation completion signal in step 401, and displays translation candidates obtained as a result of processing by the translation unit 4 in the display control unit. 8 to the display section 7 to display them (step 412).

In this case, the display control unit 8 displays the translation candidates in the translation display area 2O.
Display within b. Further, when auxiliary information is obtained from the translation unit 4 together with a translation candidate, the translated word of this auxiliary information is displayed with high brightness or reversed, for example, so that the operator can identify it.

In this state, if there is any input from the edit keys 101 to 106, the edit control unit 6 detects this with the step knob 404, and then presses the edit keys 101 to 106 to input the word or phrase indicated by the cursor. The editing process according to the type is performed as follows (step 411).

For example, by operating the insert key 101, a character is inserted before the cursor position.

By operating the delete key 102, the character string in the range indicated by the cursor is deleted.

By operating the movement key 103, the range indicated by the cursor is moved.

By operating the cancel key 104, the effects of the three edit keys 101, 102, and 103 described above are nullified.

Modifications can be made using the auxiliary information by operating the key 105.
Other dependencies of the word/phrase pointed to by the cursor display candidates.

In addition, in this embodiment system, function keys 110 to 118
For example, the following functions can be realized by input operations using .

By operating the translated word display key 110, the translated word can be displayed for each word in the translated sentence.

By operating the dictionary display key 111, the contents of the dictionary can be displayed for words in the original text.

By operating the dictionary registration key 112, new words and phrases can be registered.

By operating the dictionary deletion key 113, words and phrases registered through dictionary registration can be deleted from the dictionary.

By operating the partial translation key 114, the translated text of the portion where translation has failed is displayed.

By operating the word string search key 115, a word string can be designated on the display screen 20, and the editing control section 6 can start a word string search process for unifying writing style.

Further, cursor keys 130 to 133 include a cursor movement key 130 for moving the cursor in the x/y direction on the display screen, a unit switching key 131 for switching the unit of the distance the cursor moves, and a unit switching key 131 for moving the cursor between each display area. The cursor is composed of an inter-area movement key 132 for changing the size of the cursor, and an enlargement/reduction key 133 for reducing the size of the cursor on a character-by-character basis or enlarging it on a word-by-word basis.

Next, 1 to unify the writing style in this example system.
The operation of the one-word string search will be explained with reference to FIGS. 6 and 7.

Note that FIG. 6 is a flowchart showing the flow of the 11-word string search process, and FIG. 7 is a diagram showing a specific example thereof.

First, if the word string search is to be performed for the first time in step 601, the process proceeds to step 602, and if the search is to be performed continuously, the process proceeds to step 603.

Then, in step 602, the search key 115 is operated to specify a word string A that is a key for unifying the writing style in the translated text displayed on the screen 20.

As a result, the editing control unit 6 searches for the same word string as the specified word string A in steps 603 and 604, starting from the sentence before the translated sentence used to specify the word string (step 605).

Then, when a corresponding word string is detected (step 606
), the editing control unit 6 reads the translated text containing this word string from the translated text storage unit 5, reads the original text corresponding to the translated text from the original text storage unit 2, and displays these translated texts and the original text on the screen 20, respectively. It is displayed in the editing area 20c (step 607).

At this time, the translated text and original text currently being processed remain and are displayed in the translated text display area 20b and the original text display area 20a on the screen 20, respectively.

Thereafter, the operator edits the translated text displayed in the translated text display area 20b as necessary while referring to the edited translated text and original text displayed in the edited text display area 20c.

Thus, according to the machine translation system of this embodiment, simply by using the word string search key 115 to specify a word string that is a key for unifying the writing style in the translated text displayed on the screen 20, this word can be retrieved. It is possible to automatically detect the translated text and original text of the editing process poem including columns, and display these translated texts and the original text on the screen 20 together with the translated text and original text currently being processed, so that the operator can edit the translated text. It is possible to reduce the workload and efficiently perform translation editing processing for unifying writing style.

[Effects of the Invention] As explained above, the machine translation system of the present invention can automatically detect revised translated sentences that include word sequences that are key to unifying writing styles and the corresponding original sentences. By displaying these translations and the original text on the screen together with the translation and original text that are currently being edited, the burden of translation editing work on the operator can be reduced, and the translation editing process for standardizing the writing style can be done efficiently. It can be carried out.
