DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine translation apparatus for translating between languages such as Japanese to English, and more particularly, to a machine having a translation correction function for correcting a translation with another translation specified by a user. It relates to improvement of a translation device.

[0002]

2. Description of the Related Art At present, a machine translation apparatus has a limit in translation accuracy, and it is difficult to expect a capability equivalent to a translation expert. For this reason, work to compensate for the incompleteness of machine translation is required. One of the tasks is for the user to replace inappropriate translations in translations obtained as a result of translation with appropriate translations, and in order to support this work, instruct users to change translations in translations to other translations There is a machine translation device that obtains a corrected translation by performing only a process of replacing a designated translation in a translation with another translation and utilizing the translation in the translation.

However, in this machine translation apparatus, a grammatically incorrect translated sentence may be obtained by replacing the translated word. For example, the original sentence "I decided to be a person who has a plan" is translated into "Itwas determined on the per.
son who has aplan. Is generated, if “some” is selected as a translation of “has” corresponding to the original word “aru”, the translated text after correction is “It”
was dedicated on the person
n who some a plan. ", Which is grammatically incorrect.

A machine translation apparatus disclosed in Japanese Patent Application Laid-Open No. 64-78375 (hereinafter, referred to as Japanese Patent Application Laid-Open No. 64-78375) has been proposed to realize the replacement of a translation in a translation with another translation while preventing generation of a grammatically incorrect translation. , A conventional device).

[0005] In this conventional apparatus, dictionary information of a designated alternately-translated word is compared with dictionary information of a translated word before replacement, and it is determined whether or not grammatical change is required by the replacement of the translated word. If there is a difference in case information, part of speech, or attribute information that may require changes to the sentence structure, particles, etc. of the translated sentence, re-execute the translation from the original sentence parsing process using the specified alternate translation, Otherwise, only the replacement of the designated translation in the translation with another translation and the utilization process are performed. As a result, in the case of the above example sentence, if another translation word “some” corresponding to the original word “aru” is specified, the dictionary information of the original translation word “has” and the dictionary information of the translation word “some” are compared, and Processing is determined to be necessary, and the specified alternate translation "s
Ome "is used to re-translate from the parsing process. Therefore, in addition to the replacement and utilization processing of another translated word, grammatical processing of other parts accompanying the replacement is also performed, for example, "The pl
an was dedicated on some pe
rson. Is generated.

[0006]

However, in the above-mentioned conventional apparatus, the retranslation method can be compared with the retranslation from the parsing process by comparing the dictionary information of the designated alternately translated word with the dictionary information of the translated word before replacement. Since it is only divided into translation replacement and utilization processing, even if it is enough to re-translate from the translation generation processing, it is re-translated from the parsing processing, and it takes time to perform the parsing processing again. Was wasted. That is, the above-described conventional apparatus does not have a function of determining a case of a translation replacement that can be dealt with by retranslation from the translated sentence generation process and a function of retranslating from the translated sentence generation process. There was a problem that it might be.

Accordingly, a first object of the present invention is to provide a total of three retranslation methods: retranslation from syntactic analysis, retranslation from generation of a translated sentence, and retranslation that performs only translation word replacement and utilization processing. The object of the present invention is to provide a machine translation apparatus capable of shortening the processing time required for retranslation by adopting the above.

In the conventional machine translation, for example, “rotation of an object” is referred to as “rotating of the object”.
Although it was possible to specify the translation form, such as whether to translate as "t" or "object rotating",
If the translation needs to be replaced and you want to specify the translation form for the translated word after the replacement, you need to instruct the replacement of the translation once and re-translate, then specify the translation form and re-translate. The translation form cannot be specified at the same time as the replacement instruction, and it takes time to correct the translation.

Accordingly, a second object of the present invention is to provide a machine translation apparatus capable of simultaneously designating a translation form at the time of instructing to replace a translated word.

[0010]

In order to achieve the first object, a machine translation apparatus according to the present invention comprises a display device, an input device, and an original language dictionary for each grammatical attribute for each headword of the original language. A dictionary for translation that holds information, and that holds generator-side dictionary information for the corresponding translated word in association with each source-language-side dictionary information; and an original sentence input from the input device, the contents of the dictionary and instructions separately input. A translation unit that translates by referring also to the instruction information when there is information; a translation result output unit that displays a translation result of the translation unit on the display device;
At the time of another translation word display request, another translation word dictionary lookup unit that looks up the dictionary with the surface words of the original language in the original text and displays all the translations of the closed dictionary information on the display device, and a translation word to be replaced with the original translation word. When selected, the source dictionary information of the translated word before replacement, the generator dictionary information of the translated word after replacement, and the source word dictionary information related to them are comprehensively determined, and the analysis process of the original sentence is repeated. Whether to translate or re-translate from the translation generation process,
Retranslation method determining means for determining whether to execute only the translation replacement and utilization processing, and, when the retranslation method determination means determines to retranslate from the original text analysis processing, an original text analysis instruction based on the selected translated word Generates information and instructs the translation means to retranslate from the original sentence analysis processing, and when it is determined to retranslate from the translated sentence generation processing, generates translated sentence generation instruction information based on the selected translated word, and When the translation means is instructed to perform retranslation from the translation generation processing, and it is determined that only the translation replacement and utilization processing is to be performed, translation translation instruction information for instructing replacement with the translation is generated, and the translation Retranslation instructing means for executing only replacement and utilization processing.

In order to achieve the second object, when a translation to be replaced with the original translation is selected, a translation form candidate of the replaced translation is displayed on the display device. A translation form candidate display means for generating translation form instruction information for instructing the translation means to perform translation by the selected translation form candidate.

[0012]

In the machine translation apparatus according to the present invention, the translation dictionary holds the source word side dictionary information for each grammatical attribute for each headword of the source word, and translates the corresponding word in association with the source word side dictionary information. When the original sentence is input from the input device, the translation unit refers to the contents of the dictionary and the instruction information, if any, which is separately input, when the original sentence is input from the input device. The translation is performed, and the translation result output means displays the translation result on a display device. At the time of a request for displaying a translated word from the user, the translated word dictionary lookup unit looks up the dictionary with the surface words of the original language corresponding to the translated word in the translated sentence specified by the user, for example. When the translation is displayed on the display device and the user selects a translation to be replaced with the original translation, the retranslation method determining means determines whether the translation-side production dictionary information before the replacement and the translation-side production dictionary information after the replacement are Comprehensively determine the related source language dictionary information and determine whether to retranslate from the original sentence analysis process, retranslate from the translated sentence generation process, or execute only the translated word replacement and utilization process. . When the retranslation instruction means determines that retranslation is to be performed from the original text analysis processing by the retranslation method determination means, it generates source text analysis instruction information based on the selected translated word, and sends the original text analysis processing information to the translation means. Instruct the re-translation of, and when it is determined to re-translate from the translation generation process, instruct the translation means to generate a translation generation instruction information based on the selected translation, and instruct the translation means to re-translate from the translation generation process, When it is determined that only the translation word replacement and utilization processing is to be executed, translation word substitution instruction information for instructing the replacement with the translation word is generated, and the translating means executes only the translation word substitution and utilization processing.

Further, in the configuration provided with the translation form candidate display means, when a translation word to be replaced with the original translation word is selected, the translation form candidate of the replaced translation word is displayed on a display device to allow the user to select one. Then, translation form instruction information for instructing the translation means to translate with the selected translation form candidate is created.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, one embodiment of the machine translator according to the present invention is a machine translator for translating Japanese into English, comprising a dictionary 1, a translation unit 2, a memory 3, and a translation result output. Section 4, a translation word dictionary lookup section 5, and a retranslation method determination section 6
, A retranslation instruction unit 7, an instruction information holding unit 8, a display device 9, and an input device 10.

The dictionary 1 is a dictionary for translation. The dictionary 1 holds source word-side dictionary information for each grammatical attribute for each headword of Japanese as a source language, and associates the corresponding word with each source word-side dictionary information. Holds the generation-side dictionary information for. On the other hand,
The instruction information holding unit 8 is a unit that holds instruction information for the translation unit 2. In the present embodiment, the instruction information holding unit 8
Any of the original sentence analysis instruction information, the translated sentence generation instruction information, and the translated word replacement instruction information is set at the time of retranslation described later.

FIGS. 2 and 3 show examples of dictionary information stored in the dictionary 1. FIG. The example shown in FIG. 2 shows dictionary information relating to the original word “aru”, 101 is an original word heading, and 102-
1 to 102-3 are original language side dictionary information, and 103-1 to 103-3
-5 is generation side dictionary information. The original word “aru” has verbs “aru” and “being” and adnominal “aru”, and the verb has a case pattern of 2
Divided into That is, since there are a total of three different grammatical attributes, the source language dictionary information 1
02-1 to 102-3 are held. On the other hand, the example shown in FIG.
4 is the original language heading, 105 is the original language dictionary information, 106-1
Reference numerals 106-4 denote generation-side dictionary information. Since the original word "rotation" is interpreted only as a stem of the verb, only the corresponding original word side dictionary information 105 is stored.
These original language side dictionary information 102-1 to 102-3, 10
5 stores grammatical attributes such as part of speech and case patterns and semantic attributes such as semantic classification.

On the other hand, as for the translated word information, the translated words corresponding to the original words having the same grammatical attribute are collectively classified, connected to the corresponding original word side dictionary information on the original word side, and registered as the generation side dictionary information. That is, the source-side dictionary information 102-1 of the original word "have" is connected to the source-side dictionary information 102-1 of the original word "aru", and The generated dictionary information 103-2 and 103-3 of "be" and "exist" are connected, and the translated word "so" is added to the original word dictionary information 102-3 of the original word "aru".
"", the dictionary information 103- on the generator side of "certain"
4,103-5 are connected. Also, the source word dictionary information 105 of the source word “rotation” includes the translation “rotation” as a noun, the generation dictionary information 106-1 and 106-2 of “spin”, and the translation “rota” as a verb.
te ", generator dictionary information 106-3, 1 of" spin "
06-4 are connected. Grammar attributes such as part of speech and case patterns are registered in the generation side dictionary information 103-1 to 103-5 and 106-1 to 106-4. The translation unit 2 registers translation form variation information indicating what translation form is possible for each grammatical attribute (part of speech, case pattern, etc.) of the translated word. In addition to the registration of the translation form variation information, since the generation-side dictionary information of a plurality of translation words having different parts of speech is registered for the same source-side dictionary information, the translation unit 2 can translate in various parts of speech and usage. It is possible.

FIG. 4 is a flowchart showing an example of the operation of the machine translation apparatus shown in FIG. When a user inputs a Japanese original from an input device 10 such as a keyboard, the translator 2 inputs the original (S1) and performs a translation process (S1).
2 to S5). That is, for each original word in the input original text, the dictionary 1 is looked up and the dictionary content is loaded (S2), and then the syntax analysis process is performed on the original text using the dictionary content and a pre-installed analysis rule. (S3), the structure of the original sentence is analyzed. At this time, if the original text analysis instruction information is set in the instruction information holding unit 8, the translation unit 2 proceeds with the syntax analysis according to the instruction, but otherwise operates only according to the analysis rules. Next, in accordance with the analysis result, the dictionary 1 is loaded for the dictionary information required for generating the translated sentence by loading the dictionary 1 and the dictionary content is loaded (S4), and a translated sentence is generated using the dictionary content and the pre-installed generation rules. (S5). Also at this time, the translation unit 2 refers to the instruction information holding unit 8, and if the translation generation instruction information is set, the translation unit 2 proceeds with the translation generation according to the instruction. If not, the translation unit 2 operates only according to the generation rule. . Then, the translation unit 2 outputs the generated translation, the original original text, and bilingual information indicating the correspondence between all the original words in the original text and the translated words in the translated text to the memory 3 as translation results (S8). The memory 3 also stores dictionary information and syntax analysis results obtained as a result of dictionary lookup in steps S2 and S4. In the process after the translation is generated, if the translation information replacement instruction information is set in the instruction information holding unit 8, the translation unit 2 performs the translation word replacement according to the instruction, and performs the utilization process as needed (S
6, S7).

When the translation result including the translation is output from the translation unit 2 to the memory 3, the translation result output unit 4 displays the generated translation on the display device 9 and presents it to the user (S9).
At this time, in this embodiment, the original text is also displayed on the display device 9.

A user who sees the translation displayed on the display device 9 judges that a certain translation is inappropriate, designates an original language corresponding to the translation, and requests the input device 10 to display another translation. Then, this is detected by the translation word dictionary lookup unit 5 (S1).
0), the alternate-language dictionary lookup unit 5 displays, on the display device 9, all the translated words obtained by referring to the dictionary 1 with the surface words of the designated original language, regardless of the grammatical attributes of the translated word and the translated word. (S11). It should be noted that the alternate translation dictionary lookup unit 5 stores the dictionary contents thus retrieved in the memory 3.

Next, when the user selects one of the translation candidates displayed on the display device 9 by operating the input device 10 (YES in S12), the translation word dictionary lookup unit 5 selects the selected translation word. The translated word (the translated word after the replacement) and the original translated word (the translated word before the replacement) are notified to the retranslation method determination unit 6, and the retranslation method determination unit 6 starts to determine the retranslation method.

First, the retranslation method judging section 6 reads out the generated dictionary information of the translated word before and after replacement from the memory 3 and checks whether or not those grammatical attributes are the same (S13). In the same case (NO in S13), it can be dealt with only by the translated word replacement and utilization processing, so the retranslation instructing unit 7 is notified of the fact, and the retranslated instruction unit 7 transmits the translated word replacement instruction information specifying the translated word before and after the replacement. It is set in the instruction information holding unit 8 (S15), and the translation unit 2
At step S6 in FIG.
As a result, the translation unit 2 replaces the translated word in the translated sentence (which is stored in the memory 3) indicated by the translated word replacement instruction information with the translated word after the replacement, and uses the translated word as necessary. Do. As a result, the translated text and the bilingual information in the memory 3 are corrected, and the translated text after the correction is displayed on the display device 9 by the translation result output unit 4.

If the grammatical attributes of the translated word before and after the replacement are different (YES in S13), the retranslation method determining unit 6 determines whether or not the generated dictionary information of the translated word before and after the replacement is linked to the different original word side dictionary information. That is, it is checked whether or not the grammatical attributes of the source language are different (S14). If the grammatical attributes of the source language are different (YES in S14), the parsing structure of the original text changes due to translation replacement, and it is necessary to retranslate from the parsing process. Therefore, the retranslation instruction unit 7 is notified of the fact.
Sets the original sentence analysis instruction information specifying the translated word before and after the replacement in the instruction information holding unit 8 (S17), and causes the translating unit 2 to perform the translation again from the time of step S3 in FIG. As a result, the translation unit 2 executes the translation process again from the syntax analysis process for the original original sentence (which is stored in the memory 3), but this time the original sentence analysis instruction information is set in the instruction information holding unit 8. Therefore, at the time of parsing, the original sentence is analyzed in accordance with the instruction, the subsequent processing is executed, the translation result including the new translated sentence is output to the memory 3, and the translated sentence after the correction is output by the translation result output unit 4. It is displayed on the display device 9.

Further, when the grammatical attributes of the source language are the same (S1
4), there is no change in the analytic structure of the original sentence due to the replacement of the translated word, and this can be dealt with by re-translating from the generation of the translated sentence. The unit 7 sets the translated sentence generation instruction information specifying the translated word before and after the replacement in the instruction information holding unit 8 (S16), and causes the translating unit 2 to perform the translation again from the time of step S5 in FIG. As a result, the translation unit 2 executes the translation process again from the generation of the translated sentence based on the original original sentence analysis result and the dictionary lookup information (these are stored in the memory 3), but this time the instruction information holding unit 8 Is generated, a translation is generated according to the instruction, and the translation result including the new translation is stored in the memory 3.
And the translated sentence after correction is displayed on the display device 9 by the translation result output unit 4.

After completion of the re-translation, the information in the instruction information holding unit 8 is cleared.

Next, the operation of the machine translation apparatus according to the present embodiment will be described using a specific original text as an example. First, reference numeral 501 in FIG.
The original text "I decided to have a plan" is taken up.
It should be noted that the original word “aru” in this original text has ambiguity regarding the part of speech.

The user inputs the above-mentioned original text 501 into the input device 10
, The translation unit 2 inputs this original sentence (S1 in FIG. 4) and performs a translation process (S2 to S5). At this point, since no information is set in the instruction information holding unit 8, the translating unit 2 proceeds with the syntax analysis according to the dictionary contents of the dictionary 1 and the analysis rules, and proceeds with the generation of the translated sentence. As a result,
The translation “It was d” as shown by reference numeral 502 in FIG.
educated on the person who
has a plan. Is displayed on the display device 9 together with the original sentence.

When the user looks at the translation displayed on the display device 9 and finds that the translation is not correct, the user requests the display of the translation of the original word “aru” in the original text from the input device 10. Looks up the dictionary 1 with the original word "aru"
All the translated words are displayed on the display device 9 in the format shown in FIG. The content of FIG. 6 corresponds to the content of FIG. 2, and the translation “have” of the verb “aru” and the translation “b” of the verb “aru”
e "," exist "and the translation of the adjectival" aru "into" som "
e "and" certain "are displayed.

Next, when the user selects the translated word "some" from among the translated word candidates displayed on the display device 9 and instructs to replace the original translated word "has" with "some", the retranslation method judgment is made. The unit 6 generates the generator dictionary information 103-1 of the translated word “has” before the replacement and the translated word “some” after the replacement.
The re-translation method is determined by comprehensively judging the generation-side dictionary information 103-4 and the source-side dictionary information 102-1 and 102-3 associated with them. In this case, “has” is a translation of the verb “aru”, and “some” is the adverb “aru”.
It is determined that it affects the interpretation of the syntax analysis because the related source language dictionary information is different, and the retranslation method from the syntax analysis is determined. As a result, the retranslation instruction unit 7
Then, original sentence analysis instruction information instructing that the translated word "some" should be used as "a" is generated and set in the instruction information holding unit 8, and the translation unit 2 retranslates from the syntax analysis processing. As a result, the translated text “Theplan was decided on s” as shown by reference numeral 503 in FIG.
ome person. Is corrected.

Next, the original sentence "energy is obtained by rotation of the object" shown by reference numeral 701 in FIG.

The user inputs the original text 701 into the input device 10
, The translation unit 2 performs a translation process on this original sentence. At this point, since no information is set in the instruction information holding unit 8, the translating unit 2 proceeds with the syntax analysis according to the dictionary contents of the dictionary 1 and the analysis rules, and proceeds with the generation of the translated sentence. As a result, the translation “Energy is generated by t” as indicated by reference numeral 702 in FIG.
he rotation of the object
t. Is displayed on the display device 9 together with the original sentence.

When the user looks at the translation displayed on the display device 9 and finds no grammatical error, the translated word "rotatio"
In order to use “rotate” instead of “n”, when requesting the display of another translation of the original word “rotation”, the alternative word dictionary lookup unit 5 pulls the dictionary 1 with the original word “rotation”, and for example, as shown in FIG. All the translated words are displayed on the display device 9 in a format. The contents of FIG. 8 correspond to the contents of FIG. 3, and the noun rotation, sp
In and the verbs rotate and spin are displayed.

Next, when the user selects the translated word “rotate” from among the candidate translated words displayed on the display device 9 and instructs to replace the original translated word “rotation” with “rotate”, the retranslation method determination is made. The unit 6 generates the generator-side dictionary information 106-1 of the translated word “rotation” before the replacement.
-Side dictionary information 10 of the translated word "rotate" after replacement
The retranslation method is determined by comprehensively judging 6-3 and the source language dictionary information 105 related to them. In this case, although the grammatical attributes of the translated word before and after the replacement are different, since it is connected to the same source language side dictionary information 105, it is determined that the syntax analysis result is not affected, and the retranslation method from the translated sentence generation is determined. . As a result, the retranslation instructing unit 7 generates translated sentence generation instruction information instructing that the translated word “rotate” should be used as “rotation”, sets it in the instruction information holding unit 8, and sets the translated sentence generation processing in the translation unit 2. Retranslated from As a result, the translated sentence is corrected to a translated form as shown by one of reference numerals 703 to 705 in FIG. Here, which of 703 to 705 is to be modified follows the generation rule of the translation unit 2 in the case of the present embodiment.

On the other hand, in the conventional apparatus, since the grammatical attributes of the translated word before and after substitution are different, the translation is retranslated from the syntax analysis processing. However, the part of speech of "rotation" on the source language side is "sa varitic stem", and there is no change in the analysis result of the original sentence, so performing the syntax analysis process again is useless. In addition,
In a machine translation apparatus that performs only the replacement of a translated word, reference numeral 7 in FIG.
A grammatically incorrect translated sentence as shown at 06 is generated.

FIG. 9 is a block diagram of another embodiment of the machine translation apparatus according to the present invention.
1 is a translation form candidate display section, and 12 is a translation form instruction information holding section. FIG. 10 is a flowchart showing an operation example of the machine translation apparatus of FIG. 9, in which the same reference numerals as those in FIG. 4 indicate the same steps, and S21 to S24 indicate newly added steps. The machine translation apparatus of this embodiment is designed to be able to simultaneously specify the translation form when instructing the replacement of a translated word. Hereinafter, the operation of the machine translation apparatus of the present embodiment will be described focusing on the differences from the embodiment shown in FIG.

When the user inputs a Japanese original sentence from the input device 10 such as a keyboard, the translator 2 inputs the original sentence and performs a translation process as in the previous embodiment (S1 to S5).
5) The generated translation, the original source text, and bilingual information indicating the correspondence between all the source words in the source text and the target words in the target text are output as translation results to the memory 3 (S8). At this time, as in the previous embodiment, if there is instruction information in the instruction information holding unit 8, it is followed according to the instruction information, and if there is instruction information in the translation form instruction information holding unit 12, it is translated according to the instruction. The memory 3 also stores dictionary information as a result of the dictionary lookup in steps S2 and S4 and an original sentence analysis result. When the translation result including the translation is output from the translation unit 2 to the memory 3, the translation result output unit 4 displays the generated translation and the original original on the display device 9 and presents them to the user (S9). When the user who sees the translated sentence displayed on the display device 9 determines that a certain translated word is inappropriate, specifies the original word corresponding to the translated word, and requests the input device 10 to display another translated word, another message is displayed. The translation dictionary lookup unit 5
All the translated words obtained by referring to the dictionary 1 with the surface words of the designated original language are displayed on the display device 9 (S11), and the user waits for the selection.

When the user selects one of the translation words displayed on the display device 9 by operating the input device 10 (YES in S12), the translation word dictionary lookup unit 5 selects the selected translation word. The translated word after the replacement and the original translated word (the translated word before the replacement) are notified to the retranslation method determination unit 6, and the generated dictionary information of the replaced word after the replacement is notified to the translation form candidate display unit 11.

The translation form candidate display section 11 recognizes the grammatical attribute of the translated word from the notified translated word generating dictionary information, and translates the translated form variation information registered in the translation section 2 corresponding to the grammatical attribute. It is determined whether or not a plurality of translation forms are possible based on the above. If possible, the candidate of the translation form is displayed on the display device 9 (S21), and the user waits for selection. The translation form candidate means a variation of the translation form due to a difference in usage, word order, or the like. When the user selects one of the translation form candidates (Y in S22)
ES), the translation form candidate display section 11 generates translation form instruction information for instructing the translation section 2 to translate with the selected translation form candidate, and sets this in the translation form instruction information holding section 8. (S23). If no translation form candidate is selected by the user, no translation form instruction information is created. When the translation form is designated, the translation form is notified to the retranslation method determining unit 6.

The retranslation method judging section 6 judges the retranslation method based on substantially the same logic as in the previous embodiment. However, there is a difference in that when the translation form is designated even if the grammatical attributes of the translated word before and after the replacement are the same, the translation is determined to be the re-translation (S24). In accordance with the retranslation method determined by the retranslation method determining unit 6, the retranslation instruction unit 7 can provide the translated word replacement instruction information designating the translated words before and after the replacement if it can be dealt with only by the translated word replacement and utilization processing. Set to (S
15) The translation unit 2 is made to perform translation again from the time of step S6 in FIG. In the case of re-translation from the syntax analysis processing, the original sentence analysis instruction information specifying the translated word before and after the replacement is set in the instruction information holding unit 8 (S17), and the translation unit 2 performs the translation again from the time of step S3 in FIG. Is performed. Further, when re-translating from the translation generation, the translation generation instruction information designating the translated word before and after the replacement is set in the instruction information holding unit 8 (S16), and the translation unit 2 performs the translation again from the time of step S5 in FIG. Let it do.

Next, an example of the original sentence "energy is obtained by rotation of the object" shown by reference numeral 701 in FIG.
The operation of this embodiment will be described.

The user inputs the original text 701 into the input device 10
, The translation unit 2 performs a translation process on this original sentence. At this time, since no information is set in the instruction information holding unit 8 and the translation mode instruction information holding unit 12, the translating unit 2 proceeds with the syntax analysis according to the dictionary contents of the dictionary 1 and the analysis rules, and generates a translated sentence. Advance. As a result,
The translation “Energy i” as indicated by reference numeral 702 in FIG.
s generated by the rotati
on of the object. Is displayed on the display device 9 together with the original sentence.

When the user looks at the translation displayed on the display device 9 and finds no grammatical error, the translated word "rotatio"
Since it is desired to use “rotate” instead of “n”, when requesting the display of another translation of the original word “rotation”, the alternative word dictionary lookup unit 5 looks up the dictionary 1 with the original word “rotation” and, as in the case of FIG. Display all translations in the format shown in FIG.
To be displayed.

Next, when the user selects the translated word “rotate” from among the translated word candidates displayed on the display device 9 and instructs to replace the original translated word “rotation” with “rotate”, the translation form candidate The display unit 11 displays, on the display device 9, translation form candidates, for example, as shown in FIG. 11, based on the translation form variation information corresponding to the grammatical attribute of the translated word "rotate" after replacement. The translation form candidate corresponds to the translation form based on the difference between the transitive verb or the intransitive verb “rotate” and the difference in the translation position.

Next, the user selects, for example, “rotating of” from the translation form candidates displayed on the display device 9.
When "..." is selected, the translation form candidate display section 11 displays "ro
"rotating of"
.. Is generated and set in the translation form instruction information holding unit 12, and the translation form determination unit 6 is notified of the designation of the translation form.

On the other hand, the retranslation method determining unit 6 generates the generator dictionary information 106-1 of the translated word “rotation” before replacement and the generator dictionary information 103 of the translated word “rotate” after replacement.
-3 and the related source language dictionary information 105 and the presence / absence of the translation form are comprehensively determined, and the retranslation method is determined to be the retranslation method from the generation of the translated sentence. Therefore, in the retranslation instructing unit 7, the translation “rotate” is used as “rotation”.
Is generated and set in the instruction information holding unit 8, and the translation unit 2 re-translates from the translated sentence generation processing. As a result, FIG.
Of the reference numerals 703 to 705, the translated sentence of the reference numeral 703 corresponding to the translation form designated by the translation form instruction information is corrected. That is, in the machine translation apparatus of the embodiment shown in FIG. 1, it is up to the apparatus to determine in which of the translation forms 703 to 705, but in the machine translation apparatus of this embodiment, any one of them is used. The translation form can be specified at the same time as the specification of the replacement of the translated word.

In the above embodiment, Japanese-to-English translation is taken, but the present invention is of course applicable to translation between other languages. Finally, the operation when the machine translation apparatus of the embodiment of FIG. 9 is applied to English-Japanese translation will be described with reference to an example sentence.

The English sentence 1201 shown in FIG.
The translation unit 2 performs a translation process on this original sentence. At this time, since no information is set in the instruction information holding unit 8 and the translation mode instruction information holding unit 12, the translating unit 2 proceeds with the syntax analysis according to the dictionary contents of the dictionary 1 and the analysis rules, and generates a translated sentence. Advance. As a result, if a translated sentence “the sailing boat is interesting” as indicated by reference numeral 1202 in FIG. 12 is obtained, this translated sentence is displayed on the display device 9 together with the original sentence. In this translation, the original word “sailing” is a noun, and the translated word corresponds to the noun “sail”.

When the user looks at the translation displayed on the display device 9 and requests the display of another translation of the original word “sailing” corresponding to the translation “hosai”, the another translation word dictionary lookup unit 5 uses the original translation “sailing”. The dictionary 1 is looked up, and all translated words are displayed on the display device 9, for example, in a format as shown in FIG. FIG. 13 shows translations of nouns such as “sail” and “voyage”,
Verbal translations such as "sail", "sail" and "sail" are displayed, and intransitive and transitive verbs are distinguished and displayed.

When the user selects a translation word “sail” from the translation candidates displayed on the display device 9 and instructs to replace the original translation word “sail” with “sail”, a translation form candidate The display unit 11 displays a plurality of translation form candidates, for example, “sail (boat)” and “sail (boat), based on the translation form variation information corresponding to the grammatical attribute of the translated word“ sail ”after replacement. ",
"Sailing (boat)" is displayed on the display device 9 in the format shown in FIG.

Next, when the user selects, for example, “sail” from the translation form candidates displayed on the display device 9, the translation form candidate display section 11 displays “sailin”.
Translation form instruction information indicating that “sail” should be used as the translation form of “g” is generated and set in the translation form instruction information holding unit 12.

On the other hand, the retranslation method judging unit 6 generates the generator side dictionary information of the translated word “Sailing” before the replacement, the generator side dictionary information of the translated word “Sailing”, and the original language side information related to them. Judging comprehensively whether or not the translation form is specified,
Determine the retranslation method. In this case, the translated word before sailing, “Sailing”, is a noun, and the translated word after sailing, “Sailing”, is a transitive verb, and both have different grammatical attributes. Since the latter is different for a transitive verb, the retranslation method from the parsing process is determined. As a result, in the retranslation instruction unit 7, original sentence analysis instruction information indicating that the translated word “sail” should be used as “sailing” is generated, set in the instruction information holding unit 8, and analyzed by the translation unit 2. Retranslated from processing. As a result, the translated sentence as shown by reference numeral 1203 in FIG. 12 is corrected. When the translated form “sail (boat)” is selected, a translated sentence as indicated by reference numeral 1204 in FIG. 12 is generated. When the translated form “sails (boat)” is selected, the translated form is indicated by reference numeral 1205. Such a translation is generated. If you do not specify the translation form,
One of the reference numerals 1203 to 1205 is output.

[0053]

According to the machine translation apparatus of the present invention described above, the following effects can be obtained.

The influence on the interpretation of the original text is checked by referring not only to the dictionary information on the generation side of the translated word before and after the substitution, but also to the dictionary information on the source language to which it is related. If the translation does not affect the interpretation of the original text but cannot be dealt with simply by the translation and use of the translation, the translation is re-translated from the translation generation, and the rest is performed only by the translation and use. With the optimal retranslation method, a grammatically correct translated sentence can be efficiently obtained.

In the configuration provided with the translation form candidate display means,
Since the user can also specify the translation form of the translated word at the same time as specifying the translated word, the user can efficiently perform the correction work to a more appropriate translated sentence.
