Description

Description: TECHNICAL FIELD The present invention relates to a machine translator that inputs a sentence in a certain language such as English and converts it into a sentence in another language such as Japanese.

(Prior Art) In recent years, machine translation devices have been widely used as devices for translating from one language to another.

For example, in the case of an English-Japanese machine translator, two windows are displayed, and the user can select “As we refered in the argument, there are many k
Entering "inds of Programming Languages." and instructing the translation, the translation result window displays the translation result, "There are many programming languages, as mentioned in the overview."

Furthermore, the user instructs the use of a terminology dictionary or the like and “In C Language, function are often called with s
When the user instructs translation by inputting "ome arguments.", the translation result is displayed in a window for editing the translation as "function is often called with some arguments in C language".

(Problems to be Solved by the Invention) However, in the conventional machine translator described above, when the user instructs the use of the technical term dictionary and redoes the translation of the two sentences in the above example, the first one occurs. Would be translated incorrectly as "There are many programming languages, as mentioned in the argument." Therefore, the user needs to check whether the translation results are correct for all the sentences that have been retranslated.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention compares the translation results before and after the re-translation is performed when re-translation is performed in addition to the conventional machine translation device. If there is a change, the change is displayed in a form that can be understood by the user.

(Operation) According to the above configuration, when the user performs the translation again, the changed translation result can be quickly recognized, so that the user only needs to check only the sentence whose translation result has changed, which enables efficient translation work. Becomes

(Embodiment) Hereinafter, a machine translator according to an embodiment of the present invention that converts an English sentence into Japanese will be described with reference to the drawings.

FIG. 1 is a functional block diagram of a machine translation apparatus according to an embodiment. 1 is an input of an original sentence, correction of a translated sentence, an instruction for translating an original sentence to a translated sentence, an instruction for selecting whether to input the original sentence or to correct a translated sentence, and technical terms An input unit for inputting a tool change instruction for instructing a change of a use state of a translation tool such as a dictionary; 2 associates an original sentence input from the input unit 1 with a translation result, and furthermore, the translation result is obtained before and after retranslation. An original text translation sentence pair management table that stores information (change flag) indicating whether or not there is a change, 3 is a translation execution unit that translates the original text stored in the original text translated sentence pair management table 2, and 4 is a multiple translation for the same original text. When instructed, the immediately preceding translation result storage unit that stores the immediately preceding translation result in association with the original sentence. Reference numeral 5 indicates the current translation result obtained by comparing the content of the immediately preceding translation result storage unit 4 with the content of the original sentence translation sentence pair management table 2. A translation result comparison unit that determines whether the translation result is the same as the immediately preceding translation result, and 6 reflects the original sentence input by the user and the translation result output by the translation execution unit in the original translation pair management table. An editing control unit 7 is a display unit that displays the original sentence input by the user, the translation result output by the translation execution unit, and the translation result that has been changed by re-translation so that the user can understand the change. .

FIG. 2 is a circuit block diagram of the machine translation apparatus of the present embodiment, in which 8 is a keyboard, 9 is a central processing unit (hereinafter, CPU).
Abbreviated. ), 10 are cathode ray tube displays (hereinafter, CR
Abbreviated as T display. ) And 11 are read-only memories (hereinafter abbreviated as ROM), and 12 are random access memories (hereinafter abbreviated as RAM).

The input means 1 shown in FIG. 1 is operated by the keyboard 8, the original / translation sentence pair management table 2 is operated by the RAM 12, and the translation execution unit 3 executes the program stored in the ROM 11 while the CPU 9 exchanges data with the ROM 11 and the RAM 12. Thus, the display means 7 is realized by the CRT display 10.

FIG. 3 is a flowchart schematically showing an embodiment of the present invention.

First, in step (3-1), the user operates the input unit 1
Choose what you want to do in the future. In other words, if the user wants to enter English text,
"English input mode" When the user wants to translate a specific English sentence, "Translation mode", when the user wants to change the usage status of a technical term dictionary, etc., "Dictionary status change mode", when he wants to end all the processing Selects "End".

If the user selects “end” by this selection operation, all the processing ends, and if the user selects any other, “English input mode”, “translation mode”, “dictionary state change mode” To three states.

When the user has completed the work to be done in each state,
It returns to step (3-1).

The operation of the English-Japanese machine translator according to the embodiment of the present invention configured as described above will be described below with reference to the flowchart of FIG.

First, in step (4-1), when the user instructs to input an English sentence, an English sentence input mode is set.

FIG. 5A is a flowchart in the English sentence input mode. First, in step (5-1), when the user inputs an English sentence from the input means 1, step (5-2)
Then, the contents are written into the original / translated sentence pair management table 2 by the editing control unit 6. Next, in step (5-3), the edit control unit 6 refers to the original-translated sentence pair management table 2 and
Display is performed on the display means 7.

When the user reads the following two statements, “As we refered in the argument, there aer many k
inds of Programming Languages. "“ In C Language, functions are often called with
Fig. 5 (b) shows the contents of the original sentence translation sentence management table 2 when "some arguments." is input. Fig. 5 (c) shows the state of the editing screen at this time.

This completes the process in the English input mode.
Proceed to step (4-2) in the figure.

In step (4-2), the user instructs translation, and the mode becomes the translation mode.

FIG. 6A is a flowchart in the translation mode.

First, in step (6-1), when the user specifies the original text to be translated from the input means 1 by using a pointing device such as a cursor key or a mouse, or by specifying a sentence number, in step (6-2), The editing control unit 6 refers to the original-translation sentence pair management table 2 and determines whether or not the specified original has already been translated based on whether or not the translated sentence has already been written. Here, it is assumed that a translation is designated for the sentence input in step (4-1). In this case, since the sentence has not been translated, the process proceeds to step (6-4).

In step (6-4), the edit control unit 6 refers to the original sentence translated sentence pair management table 2 and passes the original sentence to the translation executing unit 3. The translation execution unit 3 receives the original sentence, returns the translation result to the editing control unit 6, and proceeds to step (6-5).

In the above example, the translation results are as follows: "As mentioned in the outline, there are many programming languages." In C language, relations are often called with several outlines.

In step (6-5), the edit control unit 6 converts the translation result received from the translation execution unit 3 into the original sentence pair management table 2.
Write to.

Next, in step (6-6), the translation result comparison unit 5 compares the translation in the original text translation sentence pair management table 2 with the translation stored in the immediately preceding translation result storage unit 4. In the example above, it is the first translation, so the translation result has not changed.

In step (6-7), the translation result comparison unit 5 determines whether the translation result has changed before and after retranslation.

Further, in step (6-8), as a result of the determination, if the value has changed, the change flag = on, and if not, the change flag = off is written in the original sentence translation sentence management table 2.
In the above example, since the translation result did not change, the change flag is set to off.

In step (6-9), when the edit control unit 6 refers to the original-translated sentence pair management table 2 to change the original sentence and the translated sentence, and the translation before and after the translation (as shown in FIG. 6 (f)) 2), and outputs it to the ideographic means 7 in a form that the user can understand. The symbol in the column of the number in FIG. 6 (f) indicates that the translation has changed.

FIG. 6 (b) shows the contents of the original sentence translation sentence pair management table 2 when the user instructs translation of the above example sentence. FIG. 6C shows the editing screen at this time.

Since the processing in the translation mode ends here, the process proceeds to step (4-3) in FIG.

In step (4-3), the user changes the use state of the technical term dictionary and the like, and proceeds to step (4-4).

Step (4-4) is a case where the user instructs the translation again. In this case, the mode shifts to the translation mode. That is, the process proceeds to step (6-1) in FIG.

“As we refered in the argument, there are many k
inds of Programming Languages. "“ In C Language, functions are often called with
Then, it is assumed that the translation is instructed again for "some arguments." Then, in step (6-2), the edit control unit 6 refers to the original-translation sentence pair management table 2 and this time, it is determined that "already translated". judge. Accordingly, the process proceeds to step (6-3), and in step (6-3), the translation result immediately before the editing control unit 6 performs retranslation is stored in the immediately preceding translation result storage unit 4.

In step (6-4), the edit control unit 6 refers to the original sentence translated sentence pair management table 2 and passes the original sentence to the translation executing unit 3. The translation execution unit 3 receives the original sentence, returns the translation result to the editing control unit 6, and proceeds to step (6-5).

In the above example, the translation results are as follows: "There are many programming languages, as mentioned with arguments.""In C language, functions are often called with some arguments."

In step (6-5), the edit control unit 6 converts the translation result received from the translation execution unit 3 into the original sentence pair management table 2.
Write to.

Next, in step (6-6), the translation result comparison unit 5 compares the translation in the original text translation sentence pair management table 2 with the translation stored in the immediately preceding translation result storage unit 4.

In step (6-7), the translation result comparison unit 5 determines whether the translation result has changed before and after retranslation.

Further, in step (6-8), as a result of the determination, if the value has changed, the change flag = on, and if not, the change flag = off is written in the original sentence translation sentence management table 2.
In the above example, since the translation result has changed, the change flag is set to on. FIG. 6D shows the contents of the original-translated sentence pair management table 2 at this time, and FIG. 6E shows the immediately preceding translation result storage unit 4.
FIG. 6 (f) shows the state of the screen.

In step (6-9), the editing control unit 6 refers to the original-translated sentence pair management table 2 to display the original sentence and the translated sentence, and, if the translation has changed before and after the translation, in a form that the user can recognize the change. 7 is output. This is followed by a processing routine for determining whether to use the translation of the original translation pair management table or the translation of the immediately preceding translation result storage unit 4.

The translation result of the translation execution unit 3 can of course be modified by the user and the corrected translation can be treated as the translation result.

(Effect of the Invention) As described above, according to the present invention, when the user performs a translation again, it is made clear to the user whether or not the translation result has changed compared with the previous translation. Therefore, even when a large number of sentences are re-translated, the user only needs to check the sentences whose translation has changed, and the translation can be performed efficiently.
