Description
The present inventlon relates to a machine transla-tion system for processing an original sentence oE a first language to obtain a translated sentence of a second language and, more particularly, to a machine translation system which can improve translation efficiency.
In recent years, various machine translation sys-tems for translation using a computer system have been developed, e.g., a processing system for transla-ting English sen-tences into Japanese sentences or vice versa, and the like.
A basic processing operation in these systems will be briefly described. Morphemes constituting an input original sentence or its sentence structure is analyzed to divide the original sentence into predetermined processing units, e.g., words (or phrases). A trans-lation dictionary is referred to for each processing unit to obtain a translated word (or phrase) corre-sponding to the processing unit. The translated words (or translated phrases) are combined in accordance with a given translation rule, thus obtaining a translated sentence.
However, since a reliable technique Eor interpret-ing the meaning of a natural language has not yet been established, it is difficult to immediately obtain an appropriate translated sentence through the machine translation. More specifically, an English word "find", *
for example, has meaning.s includiny "to learn", "to perceive~, "to come upon", "to attain", "to solve", "to detect", "to uncover"~ and "to discover". When this word must be translated into Japanese, it has different translated words corresponding to the above meanings.
In this manner, a single original word often has a plurality of -translation possibilities. In this case, selection of a translated word possibility largely influences the translation quality from an original sentence into a translated sentence.
In a conventional system, a plurality of transla-tion possibilities corresponding to a processing unit (original word) are presented to an operator, and the operator determines and selects an appropriate translat-ed word to constitute a translated sentence.
However, even if a translated sentence is obtained in this manner, an inappropriate translated word often still remains in the translated sentence. For this reason, the operator must correct the inappropriate translated word in the translated sentence through post-edit processing.
When such edit processing is performed, if a dis-play device has a fixed display format -Eor the transla-tion result, this results in very poor operability.
For example, when a translated sentence including translated words to be corrected and its original sentence are displayed to correspond to each other ~s~
and translation/edit processing ls per~ormed while comparing the two sentences, this allows easy under-s-tanding of the correspondence between the two sen-tences. However, it is hard to grasp consistency or context in the document. As a result, even though appropriate translated words can be obtained for each translated sentence, the translated sentence may be inappropriate in the entire document.
In contrast to this, original sentences and their translated sentences can be displayed continuously, respectively. In this case, the above-mentioned draw-backs can be compensated for, and the context or con-sistency in the entire document can be satisfactorily grasped.
However, with this method, it is difficult to easily and reliably grasp the correspondence between the original and translated sentences and that between orig-inal and translated words therein.
The efficiency of the translation/edit processing is impaired in accordance with display formats of the translation result, thereby interfering with effective post processing.
It is an object of the present invention to provide a machine translation system with which conte~t or con-sistency in a document can be appropriately grasped, andthe correspondence between an original sentence and a translated sentence can be easily understood to allow , . .

efficient translation/edit processiny.
According -to -the present in~ention, a machine translation system performs translation processing of an original sentence by referring to linguistical infor-mation necessary for translation stored in a dictionary section, and the resultant translated sentence and theoriginal sentence are displayed to perform edit process-ing of the translated sentence. In this system, the original and translated sentences are managed to corre-spond to each other. Upon switching of a display modeof a display section, only the original or translated document is continuously displayed on a main portion of the display section, or a display screen of the display section is divided, 50 that the corresponding sentences of the original and translated documents are displayed in correspondence with each other. In this manner, the translation result can be displayed in an appropriate format in acccordance with translation/edit state for the translated sentence.
According to the present invention, since the display format of the original sentence and/or the translated sentence can be appropriately changed upon switching of the display mode. When the original and translated sentences are displayed to correspond to each other, translation/edit processing for the translated sentence can ~e effectively performed while clearly understanding the correspondence therebetween. When only the original sentences are displayed successively as a document, this allows easy understanding of the context in the docurnent. In addition, when the trans lated sentences are successively displayed as a docu-ment, this also allows easy understanding of the context in the document.
Therefore, it is easy for an operator to determinethe quality of the translation result and to perform a translation/edit operation, thus effectively obtaining a translated sentence of appropriate linguistical expression.

An English sentence input at input section 1 com-prising a keyboard is stored in original storage section
2 as an original sentence to be translated.
Translation section 4 is operated under the control of edit control section 3. Translation section 4 refers to linguistical information necessary for translation processing prestored in dictionary section 5 to sequen-tially translate predetermined processing units of the original sentence stored in section 2.
Note that the linguistical information stored in dictionary section 5 includes, e.g., inflection (regular and irregular inflection) information 5a, word (translated word) information 5b, analysis grammar ~L~S~
information 5c, conversion grarnmar inEormation 5d, generative grammar infortnation 5e, and morpherne genera-tive grammar information 5f. Japanese sentences as translated sentences, which are obtained through machine translation by referring to the linguistical informa-tion, are sequentially stored in translation storage section 6.
Edit control section 3 drives display control sec-tion 7 to simultaneously display, on display section 8, the English and Japanese sentences respectively stored in sections 2 and 6, so that the display positions of the corresponding sentences are arranged side by side, thus preparing for post-edit processing for the trans-lated sentences. The post-edit processing is executed by, e.g., referring to the linguistical information stored in dictionary section 5 in accordance with con-trol infcrmation input from input section 1.
The translated sentences (Japanese sentences) corresponding to the original sentences (English sen-tences), which are subjected to the post-edit process-ing, are hard-copied by printer 9.
Fig. 2 illustrates a keyboard constituting input section 1. The keyboard includes charactsr data input key group la, translation instruction key group lb, edit key group lc, function key group ld, cursor control key group le on display section ~, and the like.
Fig. 3 illustrates a display screen of display ~5~
section 8 for displaying the original and translated sentences. In this embodiment, the display screen is divided into three regions, edit information reyion 8a at an upper side of the screen, original display region 8b a-t the left of the screen, and translation display region 8c at -the right of the screen~ The input origi-nal sentences stored in storage section 2 are sequen-tially displayed on region 8b, and the translated sen-tences stored in storage section 6 are displayed on region 8c at positions corresponding to the original sentences. Note that informa-tion necessary for transla-tion processing, e.g., translation possibili-ties, which are searched from dictionary section 5 and are subjected to translation processing, is displayed on region 8a.
Fig. 4 shows a basic operation sequence of the system shown in Fig. 1. Edit control section 3 discrim-inates translation end information supplied from trans-lation section 4 and various key information input from input section 1 in accordance with the operation se-quence shown in Fig. 4, and controls the translation/
edit processing in a conversational manner.
Edit control section 3 causes display section 8 to display the original and translated sentences side by side in the first display mode, as shown in Fig. 3 (step O). Section 3 then monitors a translation proc-essing state in translation section 4 (step A). When section 3 detects completion of the translation ~2S~
g processing for a single original sentence, it causes storage section 6 ~o gtore the translated se~tence and causes display section 8 to display it in correspondence with its original sentence (step B).
During the translation processing in translation section 4 or when no translation processing is per-formed, section 3 discriminates key information input from input section 1 (steps C, D, E, and F). If the input key information represents a "translation instruc-tion key" (step C), section 3 transfers the input origi-nal sentence stored in storage section 2 to transla-tion sec-tion 4 to initiate the translation processing (step G).
If the input key information represents a "charac-ter key" (step D), its character code is stored in aninput bu~fer (step H) and is also stored in storage section 2, and the character (character pattern) is displayed on display section 8 (step I). When the characters corresponding to the character codes stored in the input buffer are displayed, an original sentence input from section l is displayed.
If the input key information represents an "edit key" (step E~, edit processing associated with the edit key is executed for the translated sentence (step J).
Similarly, if the input key information represents a "function key" (step F), processing corresponding thereto is executed (step K).
If there is no key inEormation or if the input key inEormation is other than the above-mentioned keys, other processing, e.g., hard-copy output of the trans-lated sentence stored in section 6 (by means of printer 9), is executed.
With this operation sequence of edit control sec tion 3, when an operator operates character input key group la of the keyboard to input characters, the character information is sequentially set in the input buffer, and is also stored in storage section 2 as an original to be translated (steps D and H). Tne inpu-t original sentence is displayed on region 8b of section 8 (step I).
If translation instruction key lb is opera-ted at an arbitrary time during a character input opera-tion, e.g., when inputting of one sentence is completed, the trans-lation processing for the input original stored in the input buffer is started in accordance with the key input (steps C and G). Upon completion of the translation processing, the translated sentence obtained there-through i5 displayed on region 8c of section 8 (steps A
and B).
If the input original sentence must be edited, e.g., corrected, for example, cursor control key group le is operated to adjust a cursor position at a correc-tion position during the original sentence input opera-tion using key group la, and the edit processing is then ~;~5~
executed by operating edit key group lc, e.g., correct, insert, delete keys, and the like (steps E and J)O
In this manner, the basic operation of the machine translation processing is controlled.
The translation processing ~step G) for the origi-nal sentence is executed, e.g., as follows.
Fig. 5 shows a processing sequence of the transla-tion processing (step G).
Translation section 4 first receives an original sentence to be translated (step P), and analyzes the input original sentence in units of morphemes (step Q).
Morpheme analysis processing includes processing for converting an original word, which is, for example, conjugated or inflected, into its original form (funda-lS men-tal form), using inflection dictionary 5a stored in dictionary section 5. For the morpheme analyzed origi-nal words, their part-of-speech information and -trans-lated word information and other properties are derived with reference to word information 5b (step R). This processing is performed by accessing word information 5b using the original word as a keyword.
Sentence-structure analysis of the original sen-tence is performed (s-tep T) under the predetermined analysis control according to analysis grammar informa-tion 5c (step S). Sentence-structure analysis is repetitively performed until it is successful. With this sentence-structure analysis, the arrangement of part-of-speeches of the original words constitutiny the original sentence, their modiEication relationship, the mode of tense, and the like are obtained.
Thereafter, the analyzed sentence structure is converted to the sentence structure of the translated sentence using conversion grammar information 5d (step U). In other words, the sentence structure of an English sentence (original sentence) is converted to that of a Japanese sentence (translated sentence) us-ing conversion grammar information 5d. If sentence-structure conversion is unsuccessful, it is determined that sentence-structure analysis of the original sen-tence is erroneously performed and is performed again.
Translation possibilities obtained for the respec-tive words of the original sentence based on the sen-tence structure of the translated sentence are sorted in a word order according to the linguistical format of the translated sentence to obtain a translated sentence possibility corresponding to the original sentence (step V). This sentence-structure generation processing is executed in accordance with generative grammar infor-mation 5e. The translated word possibi~ities constitut-ing the translated sentence possibility are conjugated and inflected in accordance with the sentence-structure generation result and morpheme generative grammar information 5f, thus completing the translated sentence (step W).
The translated sentence corresponding to its oriyi-nal sentence obtained through the translation processing is stored in storage section 6, and is displayed to correspond with the original sentence. If a plurality of translated sentences corresponding to a single origi-nal sentence are obtained, for example, only one trans-lated sentence is displayed and, at the same time, a message indicating the presence of other translated sentences is displayed.
After the translated and original sentences are displayed on display section 8, if there is an input representing edit key lc, the following translation/edit processing for the translated sentence is performed.
Basically, the translation/edit processing for the translated sentence is realized by executing processing corresponding to operated edit key lc with respect to a word (original word, original phrase, translated word, or translated phrase) indicated by the cursor on the screen of display section 8. More speciEically, this processing is performed as follows:
(1) Upon operation of an insert key, a character is inserted before a cursor position.
(2) Upon operation of a delete key, a character string within a range indicated by the cursor is deleted.
5 (3) Upon operation of a move key, a character string within a range indicated by the cursor is moved.
(4) Upon operation of a cancel key, respective edit functions specified by the corresponding keys are made invalid.
(5) Upon operation of a modification key, other modifi-cation possibilities of a word indicated by -the cursor are displayed.
When function key 16d is operated, the following functions can be used in the translation/edit processing for the translated sentence.
(l) Upon operation of a translated word display key, a translated word for a word in an original sentence indicated by the cursor is displayed.
(2) Upon operation of a dictionary display key, the content of dictionary section 5 is displayed using a word in an original sentence indicated by the cursor as a keyword.
Translation section 4 is operated under the control of edit control section 3. Translation section 4 refers to linguistical information necessary for translation processing prestored in dictionary section 5 to sequen-tially translate predetermined processing units of the original sentence stored in section 2.
Note that the linguistical information stored in dictionary section 5 includes, e.g., inflection (regular and irregular inflection) information 5a, word (translated word) information 5b, analysis grammar ~L~S~
information 5c, conversion grarnmar inEormation 5d, generative grammar infortnation 5e, and morpherne genera-tive grammar information 5f. Japanese sentences as translated sentences, which are obtained through machine translation by referring to the linguistical informa-tion, are sequentially stored in translation storage section 6.
Edit control section 3 drives display control sec-tion 7 to simultaneously display, on display section 8, the English and Japanese sentences respectively stored in sections 2 and 6, so that the display positions of the corresponding sentences are arranged side by side, thus preparing for post-edit processing for the trans-lated sentences. The post-edit processing is executed by, e.g., referring to the linguistical information stored in dictionary section 5 in accordance with con-trol infcrmation input from input section 1.
The translated sentences (Japanese sentences) corresponding to the original sentences (English sen-tences), which are subjected to the post-edit process-ing, are hard-copied by printer 9.
Fig. 2 illustrates a keyboard constituting input section 1. The keyboard includes charactsr data input key group la, translation instruction key group lb, edit key group lc, function key group ld, cursor control key group le on display section ~, and the like.
Fig. 3 illustrates a display screen of display ~5~
section 8 for displaying the original and translated sentences. In this embodiment, the display screen is divided into three regions, edit information reyion 8a at an upper side of the screen, original display region 8b a-t the left of the screen, and translation display region 8c at -the right of the screen~ The input origi-nal sentences stored in storage section 2 are sequen-tially displayed on region 8b, and the translated sen-tences stored in storage section 6 are displayed on region 8c at positions corresponding to the original sentences. Note that informa-tion necessary for transla-tion processing, e.g., translation possibili-ties, which are searched from dictionary section 5 and are subjected to translation processing, is displayed on region 8a.
Fig. 4 shows a basic operation sequence of the system shown in Fig. 1. Edit control section 3 discrim-inates translation end information supplied from trans-lation section 4 and various key information input from input section 1 in accordance with the operation se-quence shown in Fig. 4, and controls the translation/
edit processing in a conversational manner.
Edit control section 3 causes display section 8 to display the original and translated sentences side by side in the first display mode, as shown in Fig. 3 (step O). Section 3 then monitors a translation proc-essing state in translation section 4 (step A). When section 3 detects completion of the translation ~2S~
g processing for a single original sentence, it causes storage section 6 ~o gtore the translated se~tence and causes display section 8 to display it in correspondence with its original sentence (step B).
During the translation processing in translation section 4 or when no translation processing is per-formed, section 3 discriminates key information input from input section 1 (steps C, D, E, and F). If the input key information represents a "translation instruc-tion key" (step C), section 3 transfers the input origi-nal sentence stored in storage section 2 to transla-tion sec-tion 4 to initiate the translation processing (step G).
If the input key information represents a "charac-ter key" (step D), its character code is stored in aninput bu~fer (step H) and is also stored in storage section 2, and the character (character pattern) is displayed on display section 8 (step I). When the characters corresponding to the character codes stored in the input buffer are displayed, an original sentence input from section l is displayed.
If the input key information represents an "edit key" (step E~, edit processing associated with the edit key is executed for the translated sentence (step J).
Similarly, if the input key information represents a "function key" (step F), processing corresponding thereto is executed (step K).
If there is no key inEormation or if the input key inEormation is other than the above-mentioned keys, other processing, e.g., hard-copy output of the trans-lated sentence stored in section 6 (by means of printer 9), is executed.
With this operation sequence of edit control sec tion 3, when an operator operates character input key group la of the keyboard to input characters, the character information is sequentially set in the input buffer, and is also stored in storage section 2 as an original to be translated (steps D and H). Tne inpu-t original sentence is displayed on region 8b of section 8 (step I).
If translation instruction key lb is opera-ted at an arbitrary time during a character input opera-tion, e.g., when inputting of one sentence is completed, the trans-lation processing for the input original stored in the input buffer is started in accordance with the key input (steps C and G). Upon completion of the translation processing, the translated sentence obtained there-through i5 displayed on region 8c of section 8 (steps A
and B).
If the input original sentence must be edited, e.g., corrected, for example, cursor control key group le is operated to adjust a cursor position at a correc-tion position during the original sentence input opera-tion using key group la, and the edit processing is then ~;~5~
executed by operating edit key group lc, e.g., correct, insert, delete keys, and the like (steps E and J)O
In this manner, the basic operation of the machine translation processing is controlled.
The translation processing ~step G) for the origi-nal sentence is executed, e.g., as follows.
Fig. 5 shows a processing sequence of the transla-tion processing (step G).
Translation section 4 first receives an original sentence to be translated (step P), and analyzes the input original sentence in units of morphemes (step Q).
Morpheme analysis processing includes processing for converting an original word, which is, for example, conjugated or inflected, into its original form (funda-lS men-tal form), using inflection dictionary 5a stored in dictionary section 5. For the morpheme analyzed origi-nal words, their part-of-speech information and -trans-lated word information and other properties are derived with reference to word information 5b (step R). This processing is performed by accessing word information 5b using the original word as a keyword.
Sentence-structure analysis of the original sen-tence is performed (s-tep T) under the predetermined analysis control according to analysis grammar informa-tion 5c (step S). Sentence-structure analysis is repetitively performed until it is successful. With this sentence-structure analysis, the arrangement of part-of-speeches of the original words constitutiny the original sentence, their modiEication relationship, the mode of tense, and the like are obtained.
Thereafter, the analyzed sentence structure is converted to the sentence structure of the translated sentence using conversion grammar information 5d (step U). In other words, the sentence structure of an English sentence (original sentence) is converted to that of a Japanese sentence (translated sentence) us-ing conversion grammar information 5d. If sentence-structure conversion is unsuccessful, it is determined that sentence-structure analysis of the original sen-tence is erroneously performed and is performed again.
Translation possibilities obtained for the respec-tive words of the original sentence based on the sen-tence structure of the translated sentence are sorted in a word order according to the linguistical format of the translated sentence to obtain a translated sentence possibility corresponding to the original sentence (step V). This sentence-structure generation processing is executed in accordance with generative grammar infor-mation 5e. The translated word possibi~ities constitut-ing the translated sentence possibility are conjugated and inflected in accordance with the sentence-structure generation result and morpheme generative grammar information 5f, thus completing the translated sentence (step W).
The translated sentence corresponding to its oriyi-nal sentence obtained through the translation processing is stored in storage section 6, and is displayed to correspond with the original sentence. If a plurality of translated sentences corresponding to a single origi-nal sentence are obtained, for example, only one trans-lated sentence is displayed and, at the same time, a message indicating the presence of other translated sentences is displayed.
After the translated and original sentences are displayed on display section 8, if there is an input representing edit key lc, the following translation/edit processing for the translated sentence is performed.
Basically, the translation/edit processing for the translated sentence is realized by executing processing corresponding to operated edit key lc with respect to a word (original word, original phrase, translated word, or translated phrase) indicated by the cursor on the screen of display section 8. More speciEically, this processing is performed as follows:
(1) Upon operation of an insert key, a character is inserted before a cursor position.
(2) Upon operation of a delete key, a character string within a range indicated by the cursor is deleted.
5 (3) Upon operation of a move key, a character string within a range indicated by the cursor is moved.
(4) Upon operation of a cancel key, respective edit functions specified by the corresponding keys are made invalid.
(5) Upon operation of a modification key, other modifi-cation possibilities of a word indicated by -the cursor are displayed.
When function key 16d is operated, the following functions can be used in the translation/edit processing for the translated sentence.
(l) Upon operation of a translated word display key, a translated word for a word in an original sentence indicated by the cursor is displayed.
(2) Upon operation of a dictionary display key, the content of dictionary section 5 is displayed using a word in an original sentence indicated by the cursor as a keyword.
(3) Upon operation of a dictionary registration key, a character string indicated by the cursor is registered in dictionary section 5 as a new word or phrase.
(4) Upon operation of a dictionary clear ke~, the registered new words or phrases are cleared.
(5) Upon operation of a partial translation key, a partial translation for an original sentence which is indicated by the cursor and has not been successfully translated is displayed.
Note that indication oE a character string (word) by means of the cursor is perEorrned while moving the cursor on the display screen using cursor moviny keys le and enlarging or reducing a cursor size by a cursor control key.
Upon use of the above functions, post processing, e.g., correction of translated words, for the translated sentence is performed in a conversational manner.
The basic translation/edit processing in this system has been described. In addition to this, the system of this embodimen-t has the following display control function.
Original sentences are sequentialy input from input section 1 and are stored in storage section 2 using a forma-t, e.g., shown in Fig. 6A. In this case, these original sentences are stored in section 2 to be managed in terms of their storage starting addresses and the number of characters constituting each sentence. In contrast to this, the translated sentences obtained from the corresponding original sentences are stored in stor-age section 6 using a format, e.g., shown in Fig. 6B, to be managed in terms of their storage starting addresses and the number of characters constituting each sentence in the same manner as original sentences.
Edit control section 3 manages the original and translated sentences to correspond to each other using their storage starting addresses in storage sections 2 and 6 as pointers, as shown in Fig. 6C. More specifi-cally, original sentence #l is stored from address 0 of r~ 3 ~ 16 -storage section 2, and translated sentence #1 is stored from address 0 oE storage section 6. Thus, edit control section 3 manages sentences #1 to correspond to each other, so that it sets an original-sentence pointer for sentence #1 to be (0) and sets a translated-sentence pointer Eor sentence #l to be (0). Similarly, since original sentence #2 is stored from address 117 of sec-tion 2 and translated sentence #2 is stored from address 126 of section 6, edit control section 3 manages these sentences to correspond to each other, so as to set the original-sentence pointer to be (117) and set the translated-sentence pointer to be ( 126 ) .
Display control section 7 controls the original and translated sentences managed and stored in sections 2 and 6, respectively, as follows, in accordance with a display mode designated from the keyboard of input section 1 (e.g., function keys ld).
More specifically, since display control section 7 executes display control, in step O shown in Fig. 4~ in the first display mode in which the original and trans-lated sentences are displayed to correspond to each other, the first display mode is selected in the normal state. In the first display mode, display of the origi-nal and translated sentences stored in sections 2 and 6 is controlled in accordance with a control sequence, e.g., shown in Fig. 7.
More specifically, the original-sentence and translated-sentence pointers associated with the first sentence number are derived from a table shown in Fig. 6C (step a). An original sentence specified by the original-sentence pointer is derived from storage sec-tion 2 (step _). Similarly, a translated sentencespecified by the translated-sentence pointer is derived from section 6 (step c).
Thereafter, the original sentence obtained in step b is displayed on region 8b of display section 8. In this case, the original sentence is displayed in a new paragraph after its sentence number, as shown in Fig. 8A, so as to distinguish it from the previous sentences. The translated sentence obtained in step c is displayed on region 8c of section 8, so that its display position is aligned with the display start line position of the corresponding original sen-tence. As a result, the original and translated sentences are dis-played on the respective display regions dividing the display screen so that their display start line posi-tions coincide with each other.
In this manner, after a single original sentenceand its translated sentence are displayed to correspond to each other, it is checked in step f if there is a margin for displaying other sentences on the remaining display regions.
If YES in step f, the sen-tence number is incre-mented by one (step ~), and the next original sentence and the corresponding translated sen-tence are similarly read out. When this processing is repeated sequential-ly, a plurality of original sentences and translated sentences corresponding thereto are displayed to corre-spond to each other.
Display control in the second and third display modes is performed as one processing ~step K in Fig. 4) corresponding to an operated func-tion key.
Fig. 9 shows detailed processing (step K in Fig. 4) corresponding to the function keys.
In -this case, function keys ld on the keyboard as input section 1 include an "original-sentence key" for designating an original display mode as the second display mode and a "translated-sentence key" for designating a translation display mode as the third display modeO
When function key ld i5 depressed, it is checked in step k whether the depressed function key is the "original-sentence key" or "translated-sentence key" or other key. If it is determined in step k that the depressed key is other than the "original-sentence key"
and the "translated-sentence key", the flow advances to step ~, and processing corresponding to the depressed key is executed, thus ending the processing (the flow returns to step A in Fig. 4).
If the depressed key is the "original-sentence key", since the second display mode for displaying only - ` ~zs~
the original sentence is selected, display control sec-tion 7 successively reads out the original sen-tences stored in storage section 2, and successively displays a plurality of original sentences using all or almost all the display screen (i.e., interrupting division display of display regions) (step m), as shown in FigO 8B.
Thus, the operation mode is switched to an edit mode for the original sentences, and edit processing using character keys la, edit keys lc, and the like is execut-ed until an end key is depressed (steps n and o). Whenthe end key is depressed, the first display mode is restored (step ~: processing shown in Fig. 7), thus ending the processing (the flow returns to step A in Fig. 4).
If the depressed key is the "translated-sentence key", since the third display mode for displaying only the translated sentences is selected, display control section 7 successively reads out the translated sen-tences stored in storage section 6, and displays a plurality of translated sentences using all or almost all the display screen of display section 8 (i.e., interrupting division display of the display regions) (step ~), as shown in Fig. 8C. q'he display mode is thus switched to an edit mode for the translated sen-tences, and edit processing using character keys la, edit keys lc, and the like is executed until the end key is de-pressed (steps r and _). When the end key is depressed, the first display mode (step _) is restored ln the same manner as in step O in Fig. 4, thus ending the process-ing (step t: the processing in Fig. 7), thus ending the processing (the flow returns to step A in Flg. 4).
Display of the original or translated sentences in step m or ~ is made by successively reading out a plurality original or translated sentences as long as the display region has a margin.
With the system of this embodiment which performs display control described above, the original sentences are successively displayed in the second display mode to allow easy understanding of the entire original docu-ment. In the third display mode, the translated sen-tences are successively displayed to allow easy under-standing of the entire translated document. In addi-tion, in the first display mode, the original and trans-lated sentences are displayed to correspond to each other to allow easy and reliable understanding of the correspondence between original words and translated words, thus efficiently supporting the translated-sentence correction processing.
Therefore, an operator can confirm the context or consistency of translated sentences while grasping the context or consistency of original sentences, and can carry out effective translation/edit processing of original and translated sentences displayed to corre-spond with each other.
~25i~
According to the system of the present invention, translated sentences having appropriate linguistical expression can be obtained taking the context oE origi~
nal sentences into consideration. In addition, simple, efficient translation/edit procegsing can be realized.
Note that the present invention i5 not limited to the above embodiment.
For example, the format for divisional display regions oE display section 8 can be appropriately deter-mined in accordance with the specifications of thesystem.
When original and translated sentences are dis~
played to correspond to each other, a difference in sentence lengths caused by different linguistic forms may occur. In this case, if a predetermined number of blank lines are displayed below each dislayed original sentence, -the display start line position of each trans-lated sentence can be aligned with that of a correspond-ing original sentence.
Switching control for the display modes is not limited to that described above. For example, switching control can be performed by interruption processing by means of keys. Alternatively, switching control can be performed only during specific processing, e.g., edit processing.
Various other changes and modifications may be made within the spiri-t and scope of the invention.
Note that indication oE a character string (word) by means of the cursor is perEorrned while moving the cursor on the display screen using cursor moviny keys le and enlarging or reducing a cursor size by a cursor control key.
