Description

The present invention relates to a translation support apparatus that translates a document in a language into another language, and more particularly to a translation support apparatus that performs translation by linking a machine translation apparatus and a translation memory apparatus.

  2. Description of the Related Art Conventionally, machine translation devices, translation memory devices, electronic dictionary devices, Internet term search devices, summary creation devices, and the like are known as translation support devices that translate English sentences into Japanese sentences, for example.

  A machine translation device is a computer system that translates a language into another language. After performing syntax analysis that converts the word order by focusing on the grammatical structure of the sentence to be translated, each machine translates each word based on information in the sentence. Semantic processing that interprets meaning and translates it.

  Machine translation devices currently do not have translation accuracy that can withstand actual translation work, but if you specialize in areas where regular sentence patterns and phrases frequently appear, you can generate a much larger number of documents than humans. Can be translated in style and translation. In addition, it is possible to translate with high accuracy and efficiency for words such as tables that have a fixed translation.

  The translation memory device accumulates the parallel translation of the translation target sentence and the translation sentence in the parallel translation database, searches the parallel translation database using the translation target sentence as a search key, and matches or is close to the parallel translation sentence that matches the translation target sentence. Display a translation similar to the sentence. This translation memory device is used for actual translation work, and contributes to quality improvement such as unification of style and translation, but efficiency is not so high.

  The electronic dictionary device is a support device that retrieves words and examples thereof from a CD-ROM or Internet homepage in order to make dictionary lookup work more efficient.

  The Internet term search device is a search engine or the like, and is a support device that searches a document including the word from a home page on the Internet using a word as a search key.

The summary creation device creates a summary of a target document when performing a large amount of translation work, and it is easy to translate by obtaining the summary.
Japanese Patent Laid-Open No. 10-254870 JP-A-9-26961

  However, such a conventional translation support apparatus includes various apparatuses such as a machine translation apparatus, a translation memory apparatus, an electronic dictionary apparatus, an Internet term search apparatus, and a summary creation apparatus, and performs translation work by combining these apparatuses. However, sufficient efficiency of translation work could not be realized for the following reasons.

  First, translated words retrieved from an electronic dictionary device or an Internet terminology retrieval device cannot be used for machine translation unless the dictionary is registered in the machine translation device, and there is a problem that it takes time and labor to register the dictionary.

  The translation memory device stores a large amount of parallel translations in the parallel translation database and uses it for searching. However, the parallel translation information stored in the parallel translation database has a different data format and cannot be imported as it is. It cannot be used on the device.

  Since the translation memory device can only perform matching at the surface level between the translation target sentence and the parallel translation sentence of the parallel translation database using the translation target sentence as a search key, the translation sentence to be originally searched for is syntactically buried.

  The translation memory device is a simple search system. For example, even if the word is different by one word and can be translated by automatically changing the word, the search result must be corrected manually.

SUMMARY OF THE INVENTION An object of the present invention is to provide a translation support apparatus, method, and translation support program that enhances automation of translation work through cooperation between a machine translation device and a translation memory device, improves work efficiency, and improves translation quality.

  FIG. 1 is a diagram illustrating the principle of the present invention.

  The translation support apparatus of the present invention includes an interface unit 10 that inputs a translation target sentence, outputs a translation sentence, and inputs / outputs instructions related to translation control, and a machine translation apparatus 12 that translates a document in one language into a document in another language, The parallel translation database 16 that stores the translation information, the translation memory device 14 that supports the translation of a document in one language into another language document by searching the parallel translation database 16, and the translation information translated by the machine translation device 12 It is characterized by comprising a data compatibility processing unit 18 that can share bilingual information translated by the translation memory device 14 and mutually import it as bilingual information.

  The bilingual database 16 includes a bilingual database 26 used in the translation memory device 14, an analyzed bilingual database 28 obtained by analyzing the bilingual text by morphological analysis and syntactic analysis, and a bilingual phrase and bilingual pattern used in the machine translation device 12. The registered dictionaries 32 and 34 are provided, and the data compatibility processing unit 18 adds the parallel translation obtained by the machine translation device 12 or the translation obtained by the translation memory device 14 to the parallel translation database 26. Adding the translated text obtained in the translation memory device 12 or the translated text translated by the user to the translated text database 26 and adding the analyzed translated text obtained by analyzing the translated text to the analyzed translated text database 28; Further, a parallel translation word and / or a parallel translation pattern is extracted from the analyzed parallel translation sentence and added to the dictionaries 32 and 34 on the machine translation apparatus 10 side.

  As a result, the parallel translation information obtained by the machine translation device is reflected in the search database used in the translation memory device, and the parallel translation information stored in the translation memory device search database is also reflected in the dictionary of the machine translation device. Since each bilingual information can be used as a common asset, the automation of the translation work is further promoted, and the work efficiency and the translation quality are expected to be improved.

  The data compatibility processing unit 18 displays the bilingual phrase candidate and the bilingual pattern candidate automatically extracted from the analyzed bilingual sentence in the bilingual database 16 with certainty. This allows the user to determine whether or not to register candidates with low certainty in the dictionary, and can also automatically register only those candidates with high certainty, which can cause incorrect translations and translations in the machine translation device. Prevents patterns from being registered.

  The translation support apparatus of the present invention further includes a similar sentence translation unit 36. When the translation memory device requests translation, the similar sentence translation unit 36 searches for a similar sentence by searching the parallel translation database using the input sentence, passes the input sentence to the machine translation apparatus, acquires the analysis result, and obtains a parallel translation base. The input word / phrase which is different by comparing the retrieval result of the above and the analysis result acquired from the machine translation device is passed to the machine translation device to obtain the parallel translation word / phrase, and the difference word / phrase in the parallel translation similar sentence is replaced.

  For this reason, when similar sentences are searched from the bilingual database, different words are automatically translated in cooperation with the machine translation device, and it is necessary to artificially correct the errors in the words of the bilingual sentences obtained from the translation memory device. Disappear.

  The translation support apparatus of the present invention further includes a structure search unit 38. The structure search unit 38 obtains an analysis result by passing the search input sentence of the translation memory device to the machine translation device via the data compatibility processing unit 18, and uses the analysis result as a search key to retrieve the structure from the analyzed parallel translation database. Search for similar translations and display them. For this reason, bilingual database searches are not surface-level matching of translation target sentences, and bilingual sentences with similar structures can also be searched.

  The translation support apparatus of the present invention further includes an expression search unit 40 that searches and displays examples of designated terms. For this reason, when neither the machine translation device nor the translation memory device has a correct bilingual phrase, the translation efficiency is improved by searching and displaying an example sentence including the phrase.

  In the translation support apparatus of the present invention, a certainty factor setting unit 42 is further provided. When the translation memory device and the machine translation device translate at the same time, the certainty factor setting unit 42 outputs the translation candidate output from the machine translation device in response to the output display of the translation candidate with a score indicating the certainty factor from the translation memory device. The candidate is displayed with a score indicating confidence.

  This is because the translation memory device displays the translation candidate with a certainty factor, but the machine translation device does not display the certainty factor of the translation candidate. From the translation candidates of the device and the opportunity translation device, it is possible to immediately distinguish the correct translation result with high certainty.

  The translation support apparatus of the present invention further includes a summary creation unit 44 that displays the meaning of the translation target document before translation. For this reason, a summary is created from the translation target document in the case of a large amount of translation work, and by translating this summary, the subsequent translation work can be predicted and translation becomes easy.

  The translation support apparatus of the present invention further includes an outline calculation unit 46 that calculates document information including the number of characters, the number of words, expressions, and the like of the translation target document and displays them in the order of appearance frequency. By document information regarding such sentence to be translated is automatically displayed, or may be the translation note in advance what kind of words and expressions, become obvious.

  In the translation support apparatus of the present invention, the interface unit 10 includes an original text display unit 20 that displays a translation target sentence, a system output display unit 24 that displays a translated sentence, machine translation, translation memory search, structure search, and terminology. And a translation editing unit 22 for performing an editing instruction including a search.

The translated text obtained in step 1 or the translated text translated by the user is added to the translated text database, and the analyzed translated text obtained by analyzing the translated text is added to the analyzed translated text database. A parallel translation word and / or a parallel translation pattern are extracted from the dictionary and added to the dictionary of the machine translation device.

  The translation support method further displays a bilingual word candidate or a bilingual pattern candidate automatically extracted from the analyzed bilingual sentence with certainty.

  The translation support method further retrieves a similar sentence by searching a parallel translation database using an input sentence when requesting translation from the translation memory device, and passes the input sentence to the machine translation apparatus to acquire an analysis result, A similar sentence translation is performed in which a different input word / phrase is compared to the machine translation apparatus by comparing the retrieval result of the above and the analysis result acquired from the machine translation apparatus to obtain a parallel translation phrase and the difference word / phrase in the parallel translation similar sentence is replaced.

  The translation support method further obtains an analysis result by passing the search input sentence of the translation memory device to the machine translation device via the data compatibility processing unit, and uses the analysis result as a search key to obtain the structure of the structure. Search for similar translations and display them.

  The translation support method further searches and displays an example of the specified term.

  The interface unit 10 includes an original text display unit 20, a translation editing unit 22, and a system output display unit 24, and inputs the translation target document 15 and outputs the translation result to the translation document 25. As this interface unit 10, for example, a translation work screen 11 as shown in FIG. 3 is prepared.

  The translation work screen 11 of FIG. 3 includes an original text display unit 20, a translation editing unit 22, a machine translation display unit 24-1, a translation memory display unit 24-2, and a parallel database match sentence display unit 35. The translation target document 15 shown in FIG.

  The translation editing unit 22 is provided with an editing display unit 106, below which a translation button 108, a translation memory button 110, a machine translation button 112, a structure search button 114, a term search as control buttons for the user to instruct a translation operation. A button 116 and an overwrite button 118 are provided.

  When the translation button 108 is operated, the same translation operation is performed as when all of the translation memory button 110, the machine translation button 112, the structure search button 114, and the term search button 116 are operated.

  The machine translation display unit 24-1 displays an original sentence as a translation target sentence and a machine-translated translation sentence. The translation memory display section 24-2 displays a sentence to be translated, a similar sentence acquired by searching the parallel translation database 16, and a parallel translation. In the parallel database matching sentence display section 35, a plurality of parallel sentence candidates matched by the search of the parallel translation database 16 by the translation memory device 14 are displayed. FIG. 4 is an example of a display during translation work using the translation work screen 11 of FIG.

  Referring back to FIG. 2, the machine translation apparatus 12 includes a machine translation unit 30, a parallel translation pattern dictionary 32, and a parallel translation phrase dictionary 34. In response to a translation request from the interface unit 10, the translation target document 15 is fetched. The sentence structure is analyzed for each sentence, the parallel translation pattern and the parallel phrase dictionary 34 are obtained by searching the parallel translation pattern dictionary 32 and the parallel translation phrase dictionary 34, and further the semantic processing is performed to create a parallel translation sentence.

  The machine translation apparatus 12 is realized by executing an independent machine translation program, and for example, “ATLAS” manufactured by Fujitsu Limited can be used.

  The translation memory device 14 cuts out the target document from the translation target document 15 in response to the translation request from the user from the interface unit 10, searches the search database 16-1 using this target document as a search input sentence, and the original language of the translation target sentence Get a translation that is close to the sentence. The translation memory device 14 is also realized as an independent program, similar to the machine translation device 12, and for example, "Translators Workbench" manufactured by TRADOS can be used.

  The bilingual database 16 includes a bilingual sentence database 26 and an analyzed bilingual sentence database 28 of the search database 16-1, and a bilingual pattern dictionary 32 and a bilingual phrase dictionary 34 on the machine translation apparatus 12 side. Among these, the parallel translation database 26 and the analyzed parallel translation database 28 are used as search memories of the translation memory device 14.

  The parallel translation pattern dictionary 32 and the parallel phrase dictionary 34 provided in the machine translation device 12 are used for machine translation by the machine translation unit 30, and are translated with the machine translation device 12 via the data compatibility processing unit 18. By sharing the data in the memory device 14, the bilingual pattern dictionary 32 and the bilingual phrase dictionary 34 are also functionally included in the category of the bilingual database 16 via the data compatibility processing unit 18.

  The data compatibility processing unit 18 constructs the bilingual database 16 so that the bilingual information obtained by the machine translation device 12 and the bilingual information obtained by the translation memory device 14 can be used as the bilingual information by sharing the data between them. To do.

  That is, the data compatibility processing unit 18 analyzes the parallel translation translated by the translation memory device 14 or the parallel translation translated by the user, adds it to the analyzed parallel translation database 28, and further extracts the translation pattern and the parallel phrase from the analyzed parallel translation. It is extracted and added to the bilingual pattern dictionary 32 and bilingual phrase dictionary 34 on the machine translation device 12 side.

  When the machine translation is performed by the machine translation device 12 and the translation is confirmed after correction by the user, the data compatibility processing unit 18 registers the confirmed parallel translation in the parallel translation database 26 and the analyzed parallel translation database 28. At the same time, the bilingual pattern and the bilingual phrase are additionally registered in the bilingual pattern dictionary 32 and the bilingual phrase dictionary 34.

  By reflecting the machine translation result and the translation memory search result in the parallel translation information by the data compatibility processing unit 18 as described above, the parallel translation information stored in the translation memory device 14 can be used by the machine translation device 12 and at the same time the machine translation device. Twelve translation results can be utilized on the translation memory device 14 side.

  When the similar sentence translation unit 36 obtains a similar sentence by searching the parallel translation sentence database 26 in response to the translation request to the translation memory device 14, the similar sentence translation unit 36 compares the search input sentence as the translation target sentence with the analysis structure and extracts a different phrase. Then, this word / phrase is translated using the machine translation device 12 to replace the different words / phrases in the similar sentence, thereby obtaining a parallel sentence.

  For this reason, even when a parallel translation result of a similar sentence in which one or more slight words or phrases are different is obtained by searching the parallel translation database 16 by the translation memory device 14, the user about the different part in the parallel translation result It is automatically corrected and translated in cooperation with the machine translation device 12 without requiring any correction, thereby greatly improving the translation efficiency of the translation memory device 14.

  Further, the structure search unit 38, the expression search unit 40, the certainty factor setting unit 42, the summary creation unit 44, and the summary calculation unit 46 provided to enhance the translation function of the present invention will be briefly described as follows.

  The structure search unit 38 analyzes the structure of the translation target sentence input by the interface unit 10, searches the parallel translation database 16 for a parallel translation sentence close to the structure, and displays it. The search result by the structure search unit 38 is displayed on the parallel database matching sentence display unit 35 of the translation work screen 11 in FIG. 3 as in the work screen in FIG.

  The expression search unit 40 uses the terminology examples and the like from the parallel translation pattern dictionary 32 and the parallel word phrase dictionary 34 of the machine translation device 12 included in the parallel translation database 16 of the translation support device of the present invention as a functional configuration, and from the Internet 45 as necessary. Search for expressions and display them on the translation screen if necessary.

  When the translation request for the same translation target document is made to both the machine translation device 12 and the translation memory device 14 from the interface unit 10, the certainty factor setting unit 42 preliminarily translates the translation result. Although the output is displayed with a certainty factor, since the certainty factor is not displayed for the translation result of the machine translation device 12, the certainty factor is also set for the translation result of the machine translation device 12 by the certainty factor setting unit 42. In addition, on the work screen realized as the interface unit 10, the translation result of the translation memory device 14 and the translation result of the machine translation device 12 are both displayed as a certainty factor, for example, as a percentage display, and either translation is performed by the user. It is made to judge whether a result can be used.

  The summary creation unit 44 creates a summary document by operating when handling a large number of translation target documents 15, and obtains a translation result for the automatically created summary document. It can be understood by the user and can facilitate the translation work.

  The outline calculation unit 46 calculates the number of appearances of words and expressions for the translation target document 15 to be translated, and displays them in the order of appearance. It is also possible to calculate and display the match rate of the translation target document with respect to the parallel translation database 16. The functions of these processing units will be further clarified in the later description.

  FIG. 5 is a flowchart of parallel translation database creation processing by the data compatibility processing unit 18 of FIG. The data compatibility processing unit 18 first performs a process of accumulating the parallel translation sentences in the parallel translation database in step S1. In the initial stage when the translation support apparatus of the present invention is started up, there is no accumulation of parallel translations. Therefore, parallel translations are extracted from the translation document 25 translated in the past and stored in the parallel translation database 26. FIG. 6 shows a bilingual sentence record 48 stored in the bilingual sentence database 26, which is composed of a combination of a translation target sentence 50 and its bilingual sentence 52.

  Referring to FIG. 5 again, when the extracted parallel translation is stored in the parallel translation database 26, the parallel translation is transferred to the machine translation device 12 in step S2, the structure is analyzed, and the analysis result is the analyzed parallel translation database 28. To accumulate. As this analyzed parallel translation, the translation target sentence 54 with analysis information in FIG. 7 obtained by the structural analysis of the translation target sentence 50 in FIG. 6 is registered in the analyzed parallel translation database 28.

  Here, the translation target sentence with analysis information registered in the analyzed parallel translation database 28 is linked to the corresponding parallel translation record in the parallel translation database 26.

  Next, in step S3 of FIG. 5, an expression that frequently appears is extracted from the analyzed parallel translation sentence in the analyzed parallel translation database 28, and the final determination is whether the user registers or not, and the determined expression is converted into a parallel translation pattern. Register in dictionary 32. Similarly, in step S4, frequently-occurring expressions are extracted from the analyzed parallel translation sentence, and after the final decision is made by the user, the determined phrase is registered in the parallel phrase dictionary 34.

  Further, when the translation memory device 14 has already stored the parallel translation text in the parallel translation database 26, the Japanese language stored in the parallel translation database 26 is converted in format and registered in the parallel translation pattern dictionary 32 and the parallel phrase dictionary 34. Is performed in step S5.

  The bilingual database 16 is created by the data compatibility processing unit 18 as well as when the translation result is determined by the machine translation device 12 as well as when the translation support device of the present invention is started up, or the translation memory device 14. Similarly, each time a translation result is determined, registration of the acquired bilingual sentence in the bilingual sentence database 26, registration in the analyzed bilingual sentence database 28, registration in the bilingual pattern dictionary 32, and bilingual phrase dictionary 34 Dynamic registration.

  FIG. 8 is an example of a parallel translation phrase extracted based on the translation target sentence 54 with analysis information in FIG. 7, and the parallel translation phrase 56 in FIG. 8A and the parallel translation phrase 62 in FIG. And is registered in the bilingual dictionary 34 on the machine translation device 12 side.

  FIG. 9 shows a translation pattern extracted from the parallel translation record 48 in FIG. 6 and the translation target sentence 54 with analysis information in FIG. 7. The translation pattern includes a translation target pattern 70 and a corresponding translation pattern 72. The record 68 is registered in the parallel translation pattern dictionary 32.

  FIG. 10 is a flowchart of another embodiment of the bilingual database creation processing by the data compatibility processing unit 18. In this embodiment, expressions and bilingual patterns that frequently appear in the analyzed bilingual sentence, and terms in the bilingual sentence database 26 accumulated in the translation memory device are displayed with a certain degree of certainty to the user. It is characterized in that the user decides whether to register a dictionary based on the degree.

  In FIG. 10, steps S1 and S2 are the same as the bilingual database creation processing of FIG. 5, and when the frequently occurring expression is extracted from the analyzed parallel sentence in step S3, a certainty is given to the extracted expression in step S4 for the user. To display. For this reason, the user can determine whether or not to register in the translation pattern dictionary 32 by looking at the certainty factor attached to the extracted expression. When the user gives an instruction to register the expression extracted based on the certainty factor, the expression selected and specified in step S5 is registered in the parallel translation pattern dictionary 32.

  Steps S6 to S8 are registration of the words extracted from the analyzed parallel translation sentence to the parallel translation word dictionary 34. In step S7, the extracted words and phrases are displayed with certainty to determine whether or not the user registers, and registration is performed. In step S8, the selected phrase is registered in the bilingual phrase dictionary 34.

  Further, in steps S9 and S10, the terms in the parallel translation database 26 on the memory side of the translation memory device 14 are similarly displayed with a certainty factor, displayed to the user, and the terms selected and designated by the user are converted in format and translated. It is registered in the phrase dictionary 34.

  In this way, when the certainty level is given to the expression or phrase extracted from the analyzed parallel translation, it is also possible to automatically perform dictionary registration for an expression or phrase having a high certainty level.

  FIG. 11 explains the processing contents of the similar sentence translation unit 36 of FIG. The similar sentence translation unit 36 refers to the parallel translation database 16 using the translation target sentence 74 as shown in FIG. 11A, for example, input by a translation request to the translation memory device 14 as a search key. It is assumed that the similar sentence 76 is acquired.

  With respect to the similar sentence 76, an analyzed parallel translation sentence is obtained by searching the analyzed parallel translation database 28 at the same time. This analyzed bilingual sentence can be used as analyzed word correspondence data 82 as shown in FIG. In the analyzed word correspondence data 82, the subject, verb, and object in the translation target similar sentence 84 are associated with the subject, verb, and object in the similar translation sentence 86 as indicated by a solid line.

  On the other hand, since the structure of the input translation target sentence 74 in FIG. 11A is not known, it is sent to the machine translation device 12 side to analyze the structure of the sentence and obtain the analyzed translation target sentence. To do.

  Then, by structurally comparing the analyzed translation target sentence and the similar sentence 76 that has already undergone structural analysis, the difference between the translation target sentence and the translation target similar sentence is determined as “We” and “Tokyo”. Can be extracted. The differences “We” and “Tokyo” extracted in this way are passed to the machine translation device 12 and “we” and “Tokyo” are acquired as parallel translation phrases by dictionary search.

  And, for “I” and “Yokohama”, which are the differences between the parallel translation similar sentences in the similar sentence 76, input by replacing “we” and “Tokyo” obtained as a translation result of the machine translation device 12. A translation 80 corresponding to the translation target sentence 74 can be automatically obtained.

  FIG. 12 is a flowchart of the similar sentence search process by the similar sentence translation unit 36 of FIG. First, in step S1, the translation target sentence requested to be translated is fetched into the translation memory device 14, and in step S2, the parallel translation database 26 and the analyzed parallel translation database 28 of the parallel translation database 16 are searched using the translation target sentence as a search key. Get similar sentences.

  Next, in step S3, the translation target sentence is analyzed by the machine translation device 12, and the analysis structure is compared between the analyzed similar search sentence and the translation target sentence to extract differences. Subsequently, in step S5, the word / phrase extracted as the difference is translated by dictionary lookup of the machine translation device 12. Finally, in step S6, the translation result obtained by the dictionary lookup of the machine translation device 12 is substituted into the different part of the similar sentence parallel translation, and the translation result is output and displayed.

  FIG. 13 is a time chart of processing operations when a translation request is made to the machine translation device 12 and the translation memory device 14 in the translation support device according to the present invention of FIG.

  In FIG. 13, the interface unit 10 operates as a main routine for performing overall control management of the translation processing operation. That is, since the interface unit 10 is provided as a translation work screen 11 as shown in FIG. 3, for example, the user performs a translation operation using the operation function of the translation editing unit 22 of the translation work screen 11.

  Specifically, when the user clicks the translation button 108 of the translation editing unit 22 on the translation work screen 11 in FIG. 11 with the translation target document input, the translation request in step S1 of the main routine by the interface unit 10 in FIG. Is sent to the machine translation device 12, and at the same time, the translation request in step S3 is made to the translation memory device.

  In the time chart of FIG. 13, the translation requests are issued in order to separate the translation operations of the machine translation device and the translation memory device, and a response to the request is obtained. The device 12 and the translation memory device 14 operate in parallel in response to the translation requests of steps S1 and S3 performed at the same time and return the translation result.

  When the translation request in step S1 is given to the machine translation device 12, the parallel translation database 16 is searched for the translation pattern dictionary 32 and the parallel phrase dictionary 34 for the expressions and phrases obtained by the structure analysis of the sentence to be translated in step S101. .

  On the parallel translation database 16 side, the dictionary search result is returned to the machine translation device 12 in step S301. Based on this, the machine translation device 12 performs machine translation of the translation target sentence in step S102. Is sent to the interface unit 10, and the translation result by machine translation is displayed in step S2.

  On the other hand, a translation request for the same translation target sentence is made to the translation memory device 14 in step S3, and the translation memory device 14 and the parallel translation database 26 provided in the parallel translation database 16 using the translation target sentence as a search key in step S201 and A search request is sent to the analyzed parallel translation database 28.

  In response to this search request, the parallel translation database 16 responds to the translation memory device 14 with the search results of the parallel translation database 26 and the analyzed parallel translation database 28 in step S302. If the response result from the parallel translation database 16 is a similar sentence, the difference between the translation target sentence and the search target sentence is compared with the result of the structural analysis in step S202 to detect the difference. In this case, in the machine translation processing in step S102, since the structure analysis result is obtained for the translation target sentence, it is not necessary to request the machine translation apparatus 12 to perform structure analysis again.

  In step S203, the machine translation device 12 is requested to perform a dictionary lookup for the difference detected by the comparison. In step S103, the dictionary lookup is performed and the result is returned to the translation memory device 14, and the translation memory device 14 receives the result. In step S204, translation is performed by replacing the dictionary lookup result with the parallel translation of the difference.

  This translation result is sent to the interface unit 10, and the translation result by the translation memory device 14, in this case, the translation result by the similar sentence translation sentence 36 is displayed in step S4. For this reason, the process of the part enclosed with the dashed-dotted line block 87 after the translation request of step S3 until the translation result of step S4 is displayed corresponds to the process by the similar sentence translation part 36 of FIG.

  In step S5, when the user corrects and confirms the translation result by the machine translation device 12 in step S2, the translation result after the correction is notified to the machine translation device 12, and a bilingual database update request is issued in step S104. Is performed on the parallel translation database 16.

  In response to this, the parallel translation database 16 updates the parallel translation database 16 in step S303. Specifically, expressions and phrases are extracted based on the analyzed parallel translations of the translation result and registered in the parallel translation pattern dictionary 32 and the parallel translation phrase dictionary 34. The confirmed parallel translation is added to the parallel translation database 26, and the analyzed parallel translation is registered in the analyzed parallel translation database 28.

  In addition, when the user makes a memory addition request for the translation result obtained in step S4 in step S6 of the interface unit 10, an addition request is made to the translation memory device 14, and an update request is made to the parallel translation database 16 in step S205. I do.

  In response to this update request, the bilingual database 16 adds the bilingual sentence to the bilingual sentence database 26, adds the analyzed bilingual sentence to the analyzed bilingual sentence database 28, and extracts the bilingual sentence after the structure analysis. The bilingual database 16 is updated by converting the data format of the expressions and phrases in the data compatibility processing unit 18 and registering them in the bilingual pattern dictionary 32 and the bilingual phrase dictionary 34 of the machine translation device 12.

  FIG. 14 is a flowchart of the structure search process by the structure search unit 38 provided in the translation support apparatus of the present invention shown in FIG. The structure search unit 38 supports the translation function of the translation memory device 14. That is, when the translation memory device 14 searches the parallel translation database 16 for a similar sentence using the translation target sentence as a search key, it searches for a sentence that is not similar as a superficial character string although it is structurally close. I can't.

  Therefore, in the structure search unit 38, the input translation target sentence is delivered to the machine translation device 12 to analyze the structure, and the analyzed translation target sentence is acquired, and the analyzed translation target sentence is used as a search key and translated. By performing a search including the analyzed parallel translation database 28 in the database 16, it is possible to search and output a sentence having a similar structure from the parallel translation database 16, thereby matching in the translation database search of the translation memory device 14. The sentence can be deep enough.

  In the process of FIG. 14 of the structure search unit 38, first, in step S1, the structure of the translation target sentence is analyzed in cooperation with the machine translation apparatus, and in step S2, the analysis result is used as a search key from the analyzed parallel sentence database. A sentence having a similar structure can be retrieved and output to the interface unit 10 for display, or provided as a similar sentence for the similar sentence translation unit 36 to perform similar sentence translation.

  FIG. 15 is a flowchart of processing by the expression search unit 40 of FIG. In this expression search process, when a target phrase requiring a search is input in step S1, the parallel translation database 16 is searched using the input target phrase as a search key, and the original sentence including the target phrase and its parallel translation are searched. And displayed on the interface unit 10. In this case, in step S2, the target word / phrase is further transmitted as a search key to the Internet 45, and an example sentence including the word / phrase or expression can be searched.

  The function of the expression search unit 40 is, for example, that when a certain English sentence is translated into Japanese, neither the translation memory device 14 nor the machine translation device 12 translates to obtain a correct translation result. However, if you do not know how to translate the expression in English to be translated, it is possible to improve the efficiency of translation work by displaying example sentences in the search by the expression search unit 40. .

    FIG. 16 is an explanatory diagram of display contents by the certainty factor setting unit 42 of FIG. In the translation memory device 14 of FIG. 2, the certainty level of the translation result is also displayed. On the other hand, the certainty factor is not displayed in the machine translation device 12.

  Therefore, when a translation request for the same translation target sentence is issued from the interface unit 10 to both the translation memory device 14 and the machine translation device 12, when the two translation results are displayed side by side as translation results, the translation memory device 14 Although the certainty factor is displayed for the translation result, the certainty factor is not displayed for the translation result of the machine translation device 12, and the user is wondering which translation result to select.

  Therefore, the certainty factor setting unit 42 displays the translation result of the machine translation device 12 with a certainty factor.

  In FIG. 16, the translation target sentence 88 is added by the certainty factor setting section 42 following the symbol “MT” indicating that the translation result 92 of the output display section 90 obtained by the machine translation apparatus 12 is machine translation. 100% is provided as the certainty level, and the translated text is displayed behind it.

  In this output display section 90, 78% and 42% are shown as the certainty behind the symbol “TM” indicating that the translation results 94 and 96 obtained by the translation memory device 14 are memory translations, and behind that. The target sentence and the bilingual sentence are displayed.

  As described above, even when the result of machine translation and the result of translation by the translation memory are mixed in the output display unit 90, the certainty factor is given to the translation result 92 of the machine translation by the certainty factor setting unit 42. It is possible to confirm and select the translation result from the translation candidates by confirming the certainty level of the translation result.

  FIG. 17 is an explanatory diagram of the contents displayed by the summary calculator 46 of FIG. In the summary calculation unit 46, the frequently used word list 100 of FIG. 17 that calculates and displays the phrase, expression, and match rate on the translation memory device 14 side for the translation target document 15 in this embodiment. In this case, a list of words calculated in descending order of appearance frequency is displayed. In the frequent expression list 102, expressions are displayed in a list in the same format as the translation pattern in descending order of appearance frequency. Further, as the match rate 104 of the translation memory, the number of match sentences in the translation target document and the match rate are listed in descending order of the match rate.

  The display unit 98 by the summary calculation unit 46 of the present invention as described above is the user can see a clear or may be translated in mind beforehand what words and expressions are translated target document, also the translation memory device 14 The translation result when used can also be predicted from the match rate, and it is possible to appropriately select translation work using both or one of the machine translation device 12 and the translation memory device 14.

  FIG. 18 is an explanatory diagram of another embodiment of the translation work screen used as the interface unit 10 of the present invention. In the translation work screen 120, an original text display unit 124 and a translation editing unit 122 are provided, and the translation work can be advanced using the translation editing unit 122.

  FIG. 19 is an example of the work on the translation work screen 120, the translation target document is displayed on the original text display unit 124, and the translation target document whose structure is analyzed is displayed on the translation editing unit 122. For example, when a translation portion is designated as shown in the inversion unit 126 for the display of the translation editing unit 122, a plurality of translation results are displayed together with the certainty factor in the translation window 128. For example, a translation result having a certainty factor of 100% is selected. So, you can translate as you edit.
