Abstract

PURPOSE:To easily execute a correcting work by retrieving automatically a character-string in an input original or version, based on a designation of a specific character-string, and displaying its character-string and a character- string in the version or the input original corresponding thereto so as to be discriminated from other part by an inversion display, etc. CONSTITUTION:When a specific character-string in an input original or version is designated by an input part, 1 based on an input operation of an operator, its character-string in the input original or version is retrieved automatically. Also, a character-string in the version or the input original corresponding to the character-string in the input original or the version which has been retrieved is checked, and parts of these character-strings are displayed on a display part 7 so as to be discriminated from other part by, for instance, an inversion display, a high luminance display, an underline display, etc. In such a way, the operator can decide at a glance the correspondence relation of each character- string in the version or the original, and the corresponding character-string in the original or the version, and a correction based on a propriety decision thereby is also executed easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a machine translation device, and particularly to a machine translation device that facilitates editing work.

(Prior Art) Machine translation devices are being developed that utilize computer technology to automatically convert an original text in a first language input using a keyboard or the like into a translated text in a second language. This machine translation device basically divides the input original text into predetermined processing units consisting of words or phrases by morphological analysis, syntactic analysis, etc., and searches a translation dictionary for each processing unit to find the corresponding translation or A translated text is obtained by finding translated words and phrases and combining them according to predetermined translation rules.

In such a machine translation device, when extracting a second language translation corresponding to a word/idiom (in the present invention, words/idioms are collectively referred to as a character string) in a first language from a word/idiom dictionary of a translation dictionary, Although the most likely translation is uniquely determined based on the co-occurrence relationship of character strings in the input original text, etc., the most appropriate translation is not necessarily output for each character string in the input original text. Therefore, in practice, as part of the editing work after the translation is completed, it is necessary to perform correction work to replace the translated words with the most appropriate ones. At this time, it is not possible to judge the suitability of each translated word by looking only at the translated text. In order to correctly judge the suitability of a translated word, it is necessary to look at how the corresponding string is used in the input source text, and even if the translated word is the same, the corresponding string in the input source document may be completely different. Because there is.

For this reason, conventionally, when correcting a translated text, the operator first searches for the required string in the input source text, then finds the string in the translated text that corresponds to the searched string, that is, the translated word, and then The process of replacing the translated word with an appropriate one is repeated.

In addition, for example, there may be a request to modify a term in the original text that corresponds to a translated word, but in such a case, similarly, search for the necessary character string in the translated text, and then search for the required character string in the original text that corresponds to that character string. You must take the steps to find the string and replace it with the appropriate string.

(Problem to be solved by the invention) In this way, with conventional machine translation devices, when modifying character strings in the translated text or the original text, the operator has to search for the same character string or match the character strings between the translated text and the original text. This poses a problem of placing a heavy burden on the operator and reducing efficiency.

An object of the present invention is to provide a machine translation device that can easily modify character strings in a translated text or an original text.

[Structure of the Invention] (Means for Solving Problems) The present invention provides an editing control section that controls each section based on information from a human resources section, in which one of the input original text in the original text storage section and the translated text in the translated text storage section. means for searching for a character string specified by an input section, and a display section distinguishing the searched character string in one of the input original text and the translated text and the corresponding character string in the other of the input original text and the translated text from other parts. The basic idea is to have a means of displaying the information in a way that is possible.
Furthermore, it has means for replacing the character string in the other of the input original text and the translated text corresponding to the character string in one of the input original text and the translated text specified by the input unit with another character string specified by the input unit as necessary. It is characterized by

(Operation) When a specific character string in the input original text or translated text is specified by the input unit based on an input operation by the operator, that character string in the input original text or translated text is automatically searched. Then, the translated text or character strings in the input original text that correspond to the character strings in the searched input original text or translated text are examined, and portions of these character strings are displayed on the display section, for example, in reverse video, in high-intensity display,
It is displayed so that it can be distinguished from other parts by underlining or the like. This allows the operator to judge at a glance the correspondence between each character string in the translated text or the original text and the corresponding character string in the original text or translated text, and makes it easy to make corrections based on the suitability judgment.

Furthermore, by adding a means to automatically replace the character string in the translated text or input original text corresponding to the character string in the input original text or translated text specified by the input part, with the character string specified by the input part, Modification becomes easier.

(Embodiment) FIG. 1 is a block diagram showing the overall configuration of an English-Japanese machine translation device according to an embodiment of the present invention.

This device has an input section 1 consisting of a keyboard, and stores an English sentence as an input source text in a first language that is input from this input section 1 or input from an input source file (not shown) based on instructions from the input section 1. An original text storage unit 2 and a translation dictionary unit 3 that stores information on various dictionaries used for translation processing.

A key 17 is provided for modifying other modifications of the word indicated by the cursor using auxiliary information.

As a function key, there is a translated word display key 19 which gives an instruction to display the translated word for a word in the translated sentence. Dictionary display key 20 for giving dictionary display instructions for words in the input original text. Dictionary registration key 21 for registering new words and phrases. Dictionary deletion key 22 for deleting words and phrases registered through dictionary registration. Partial translation key 2 to display the partial translation when translation fails
3, a search key 24 for controlling functions according to the gist of the present invention. Replacement key 25. A full replacement key 26° and a selection full replacement key 27 are provided.

The search key 24 is used to sequentially search for the same character string (word/compound) in the original text specified by the operator, and the replacement key 25 is used to search for the same character string (word/idiom) in the original text specified by the operator, and the replacement key 25 is used to search for the same character string (word/compound) in the original text specified by the operator. This is used to replace a string (translated word) with a specified string. The replace all key 26 is used to replace the translated words corresponding to all the searched character strings in the original text with the specified character string, and the select all replace key 27 is used to replace all the searched characters in the original text. This is for replacing the specified translated word among the translated words corresponding to the column with the specified character string (translated word).

Cursor keys include 10. cursor movement keys for moving the cursor in up, down, left and right directions; A unit switching key 28 for switching the unit in which the cursor moves; an inter-area movement key 29 for moving the cursor between display areas of the display section 7; It is provided with an enlargement/reduction key 30 for reducing the size of the cursor on a character-by-character basis or enlarging it on a word-by-word basis.

FIG. 3 shows an example of the layout on the screen of the display section 7. As shown in FIG. The input original text is displayed in the original text display area on the left side of the screen, and the translated text that is the translation result is displayed in the translated text display area on the right side of the screen so as to correspond to the input original text. Furthermore, the editing area at the top of the screen is used to display information necessary for various edits.

FIG. 4 shows the editing control section 9 using the input section 1 and display section 7.
This figure shows the flow of processing when performing dialogue translation processing. In interactive translation processing, an operator can appropriately edit a translated text corresponding to an input original text while interacting with the device. In steps 31 to 35, the editing control unit 9 monitors whether there is any key input from the input unit 1 or whether a translation completion signal is received from the translation unit 4, and if there is any key input, it Perform the corresponding processing.

When the operator operates any of the function keys 19 to 27, the editing control section 9 detects this in step 35, and performs the process corresponding to that function key in step 42.

When the operator operates any of the editing keys 13 to 18, the editing control unit 9 detects this in step 34, and performs processing corresponding to the editing key in step 41.

When the operator operates the cursor keys 10.28-30 or other control keys, the editing control section 9 executes step 33.
performs processing for moving the cursor in response to key operations and other processing.

When the operator inputs the original text by operating the character keys 11, the character keys are detected in step 33, and then the corresponding character codes are sequentially set in an input buffer (not shown) in the editing control unit 9 (step 38). This input original text is displayed in the original text display area of the display section 7 via the display control section 6 (step 39). After the operator enters the original text,
When the translation instruction key 12 is pressed, this is detected in step 32, and the editing control section 9 supplies the input original text in the input buffer to the translation section 4, and instructs the translation section 4 to start translation processing (step 40). ). If input editing such as correction, insertion, deletion, etc. is required while inputting the original text, the operator moves the cursor to the desired editing location using the cursor keys, and then presses the insert key 13. Editing operations can be performed using editing keys such as the delete key 14.

FIG. 5 is a flowchart showing the flow of translation processing in the translation section 4. First, when the translation unit 4 is given an input English sentence, it converts words with changes in endings, etc. into original forms (basic forms) using the inflection/inflection dictionary 3a, and performs morphological analysis (step 51).

Next, the translation of the original word broken down into each word by morphological analysis is added to the word/idiom dictionary 3 along with its part-of-speech information.
Search from b (step 52).

When a translation word is searched, in step 53, the translation candidates are controlled one by one to be subjected to syntactic analysis processing, and then the translation candidates are syntactically analyzed using the parsing grammar dictionary 3C to generate an English sentence structure ( Step 54). Next, the success or failure of the parsing is determined in step 55. If the parsing fails, the process returns to the parsing control step 53, and if the parsing is successful, the process proceeds to step 56, where the conversion grammar dictionary 3
d to convert the structure of the English sentence into the structure of the Japanese sentence. It is determined in step 57 whether or not the structure of the Japanese sentence has been rejected in this structure conversion step 56. If rejected, the process returns to the parsing step 54. Furthermore, if it is determined that the structure of the Japanese sentence is correct, the Japanese word order is determined from the Japanese structure based on the generative grammar dictionary 3e, and a syntax generation process is performed to convert it into a word string. next,
In step 59, the morpheme generation grammar dictionary 3f is used to change the word forms, etc. to complete the translated sentence of the Japanese sentence.

The translation section 4 sends a signal to the editing control section 9 each time it starts processing steps 51 to 59 in FIG. .

Returning to the flowchart of FIG. 4, when the editing control unit 9 receives the translation completion signal from the editing unit 4 in step 31, the process proceeds to step 37, where the translation candidates and auxiliary information obtained from the translation unit 4 are displayed on the display control unit. 6 and display the translation.

The display control unit 6 displays the translation candidate in the translation display area in FIG. 3 at a position corresponding to the input original text, and
If there is auxiliary information, the translated word is displayed with high brightness or reversed so that the operator can identify it.

When the editing keys 13 to 18 are pressed in this state, the editing control unit 9 detects this in step 34 and performs editing processing corresponding to each key on the word or phrase indicated by the cursor at that time. (Step 41).

Next, when the operator operates the keys 24 to 27 on a text (referred to as translated text) consisting of a pair of original and translated texts for which translation processing has been completed, the editing control unit 9 performs processing (step 42 in FIG. 4). (processing) will be explained. FIG. 6 is a flowchart showing the details of this process, and FIG. 7 is a diagram showing an example of display of the original text and translated text after the translation process has been completed.

The underline in Figure 7 and (1) (2) (3
) (1) '(2)'(3)' are added for explanation purposes and are not displayed. In Figure 7,
“system” (parts (1) and (2)) in the original <l> is both “system J (
The translated word is (1)'(2)' part).

Also, “writingtable” in the original text <2>
(Part (3)) is “des
The translation is ``Desk J ((3)' part), which is the same as the translation of ``k''.

Here, in order to make such a translation result an appropriate translation, the operator needs to change the "system" for (2) of the original text <1>.
It is necessary to replace the translation word corresponding to "m" with "system",
Also, of the translated word “desk” in the translated sentence <2>, the original sentence <2
Suppose that it is determined that it is necessary to replace the translated word corresponding to ``writing table'' from ``desk'' with ``book table.'' In such a case, the operator can easily correct the translated text by operating the keys 24 to 27 and the inter-region movement key 29, following the procedure shown in FIG.

FIG. 8 shows an example of the display on the display unit 7 in this process, in which the word "5yste II" is searched for in the original text and the translated word "system" is replaced with "system".

First, when the operator moves the cursor to the original text display area and then presses the search key 24, the editing control unit 9 detects this in step 61, and the operator inputs from the cursor position at that point using the character keys 11. A character string or a character string in the range where the operator moves the cursor using the cursor key 10 (this is referred to as character string A)
is set in an internal buffer (step 62). Here, when the operator presses the search key 24 again, the editing control section 9 detects this and finishes setting the buffer. Next, search for the character string A in the original text from the current cursor position toward the back of the translated text (
Step 64).

8(a) shows the display on the display section 7 before proceeding to step 64, and FIG. 8(b) shows the operator specifying the character string A "5yste11" in steps 61 to 63, and "5yste11" in step 64. This is the display when searching in the original text.In this case, as shown in the figure, 'System
By highlighting ", the operator can easily identify the location of the searched "5ysten+". At the same time, as shown in Figure 8 (C), the operator can easily identify the position of the searched "5ysteal". Highlight the translated word "system", which is a character string in the translated sentence. In addition, during the translation process, the order of character strings in the original text (1, 2,
3...) and the positions of their corresponding translated words, we can now determine the character string A in the original text and the translated text necessary to display the display shown in Figure 8 (C). You can see the correspondence with character strings.

Next, when the operator presses the search key 24 again, the editing control unit 9 detects this in step 65 and searches again for the next character string A after the current cursor position (step 64). As a result, the original text of Figure 7 <1>
Even if there are multiple occurrences of the same character string A in the sentence, as in -
The highlighted display moves from (1) to (2) in the original text (1>) and from (1)' to (2)' in the translated text <1>.Here, when the operator presses the inter-area movement key 29, The editing control unit 9 detects this in step 66, and the cursor moves from the original text display area to the translated text display area.At this time, the character string A
The translated word corresponding to (this is character string B) is set in the buffer (step 67).

Next, when the operator presses the replacement key 25, the editing control section 9 detects this in step 68, and when the operator inputs a character string from the cursor position at that point using the character keys 11, or the operator inputs a character string using the cursor keys 10. The character string within the range to which the cursor has been moved (this is referred to as character string C) is set in the buffer (step 69). Here, when the operator presses the replace key 25 again, the editing control unit 9 detects this in step 70, finishes setting the character string C to the buffer, and replaces the translated word corresponding to the character string A with the character string C. Replace (step 71).

FIG. 8(d) is a display when the operator inputs the characters "system" as the character string C using the character keys 11. In addition, in FIG. 8(e), in step 71, the "system"
This figure shows the display after the associated translated word is replaced with the character string C.

Next, when the operator presses the replace all key 26 after step 71 or without pressing the replace key 25, the editing control unit 9 detects this in step 72 and finishes setting the character string C to the buffer. Then, from the character string A highlighted in the original text to the final original text of the translated text, all translated words of the character string A in the original text are replaced with the character string C (step 73).

Furthermore, when the operator presses the select all replace key 27 instead of the all replace key 26, the editing control unit 9 detects this in step 74, finishes setting the character string C to the buffer, and Replace all translated words of character string A in the original text that are the same as translated word B with character string C, starting from the character string A that is highlighted and ending with the final original text of the translated text (step 75).

In addition, the operator selects the all replacement key 261 and the all replacement key 2
If you press the search key 24 again without pressing the key 7, the editing control unit 9 detects this in step 76, finishes setting the character string C to the buffer, and selects the highlighted character in the original text. The character string A is searched for in the original text from after column A toward the rear of the translated text (step 77). below,
While the operator presses the search key 24, step 78
This is detected and the next appearing character string A is searched for (step 77). Then, at an arbitrary search position, the operator presses the replace key 25. All replacement key 26. Alternatively, if the selection all replacement key 27 is pressed, steps 70, 72 .
74, the above-mentioned processing is performed, and the same processing is repeated as appropriate depending on the case.

In this way, the desired character string A in the input original text is searched,
The character string A and the corresponding character string in the translated text (translated word)
is displayed so that it can be distinguished from other parts by displaying it in reverse video, etc., and from this display, it is possible to judge the suitability of the translated word for character string A and replace the translated word, so that the suitability of the translated text can be checked while comparing it with the original text. Judgments and corrections can be made efficiently.

The present invention is not limited to the embodiments described above, and can be implemented with various modifications as listed below.

In the example, a character string in the original text is searched and the translation word of that character string is replaced with the specified translation word, but conversely, the specified translation word is searched and the character string in the original text that is the translated word is replaced. It may be replaced with the specified string. That is, the words and phrases in the original text may be corrected from the translated words. This is effective, for example, when correcting technical terms such as technical terms used in the original text. Specifically, it may be done as follows.

(1) In Fig. 6, in the first substitution, the search key 24 is pressed on the original display area, and the replacement key 25 is pressed on the translation display area to replace the translated word. Without limiting the target, when you first press the search key 24 on the original text display area, the translation replacement process starts, and conversely, when you first press the search key on the translation display area, the replacement process for the character string in the original text starts. may be started.

(2) When the search key 24 in the embodiment is used as the first replacement key that targets the original text display area, and the replacement key 25 is used as the second replacement key that targets the translated text display area, and the cursor is at an arbitrary position. When you first press the first replacement key, the cursor automatically moves to the source text display area and starts replacing the translated word, and conversely, when you first press the second replacement key, the cursor automatically moves to the translated text display area. Alternatively, the user may move to the display area and start replacing the character string in the original text.

(3) The operator specifies in advance whether to replace the translated word or replace the character string in the original text, and first Which of the second replacement keys is pressed first may be determined arbitrarily.

In the example, character string A, translated word B, and translated word C were specified in the translated text, but the system outputs a message in the editing area of FIG. The search/replacement process may be started by inputting the translated word C and the translated word C. Furthermore, instead of the operator inputting the translated word B, the system displays all the translated words of the character string A in the translated text on the screen, and the operator selects the translated word B that needs to be replaced from among them. It's okay.

Further, instead of inputting the translation word C by the operator, the translation words of the character string A in the dictionary may be restored by display, and the operator may select an appropriate translation word from among them.

The number of character strings A and translation word B is not limited to one, but a plurality of character strings A and a plurality of translation words B may be provided for each translation word B, so that the translation word C to be replaced for each translation word B may be specified.

In addition, although the example targeted translation text from English to Japanese, it is not limited to texts in which one language is replaced by another language, but texts in which one language is replaced by the same language. may be targeted. For example, in a summarization device that summarizes a certain sentence in a certain language, corresponding terms may be replaced between the original text and the summarized text.

[Effects of the Invention] According to the present invention, based on the operator's designation of a specific character string for the input original text or translated text, the character string in the input original text or translated text is automatically searched and By displaying the corresponding string in the translated text or the input original text in a way that makes it distinguishable from other parts, such as by highlighting it, the operator can easily recognize the mutual correspondence of each string between the translated text and the original text. Therefore, it becomes easier to correct the character strings in the translated text or the original text if they are not appropriate. Furthermore, if a means is added to automatically replace one character string in the input original text or translated text with a character string specified by the input section, correction becomes easier.
