Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a machine translation system in which a user can input auxiliary information regarding the expression form of a third language.

(Prior Art) In recent years, systems that use computers to mechanically translate input original texts have been attracting attention. This machine translation system basically divides the first language to be translated into predetermined processing units such as words or phrases (phrases) that are groups of words by morphologically and syntactically analyzing the original text. However, the translation dictionary is searched for each processing unit to find corresponding words and phrases, and these are combined according to predetermined translation generation rules to obtain the translation.

However, for natural languages, it is extremely difficult to reliably obtain appropriate translations, partly because semantic analysis technology has not yet been fully established.

For this reason, conventionally, multiple translation candidates obtained as a result of translation are presented to the user, and the user selects and specifies the translation candidate that is the most appropriate.
There remains a need for the user or operator to re-edit the translation into an appropriate translation.

Here, if we consider an example of Japanese-English translation that requires operator re-editing, firstly, English has a grammatical system called articles, but Japanese does not have a corresponding framework. For this reason, when translating a Japanese sentence into English, it is often not possible to obtain enough information from the original text to decide what kind of articles to generate or whether to use no articles. , the only option was to leave it to the default processing provided by the system. Naturally, this often does not meet the user's wishes, and it is even more impossible to judge the content of a document and change the default content for each document.

Second, as a variation in the way of connecting words of compound modifiers of noun phrases, which are compound words, in general, rphone
tlc-equivalent coretron
How to connect words with a hyphen like J, and r
phonetic equivalent core
There are methods such as ctlonJ that leave blanks between words, but conventional methods for connecting these words are as follows:
The system only performed one process unilaterally, and if it did not meet the user's wishes, the only option was to re-edit it.

A third example is a variation of the translation method for su-modal nouns, which can also function as verbs by adding ``...suru'' to the end of the Japanese word. In particular, when translating sentences that can be expressed as noun phrases or gerund phrases, the system has up until now decided which form of expression to use. If it did not meet the user's wishes, the only option was to re-edit it.

The fourth example is a variation of the translated expression of a Japanese sentence that ends with "...to do."

For example, it is possible to use the expression "rllovLo...", or it can be expressed using a gerund phrase. Conventionally, the system would only perform one process unilaterally, and if it did not meet the user's wishes, the user would have no choice but to re-edit it.

(Problems to be Solved by the Invention) As described above, conventional machine translation systems often do not output what the user desires when processing English articles or other translation methods that have variations, and there are opportunities for re-editing. There were many errors, and the translation efficiency was poor.

Therefore, the present invention provides variations in expression methods, such as the default processing for English article generation, the expression method for compound noun phrases, the expression method for subversive nouns, and the expression method for sentences whose clauses end with "to...". By giving the user the right to choose what processing they want the system to perform on a given item, we provide a machine translation system that can obtain the translation of the user's desired expression and minimize the amount of re-editing. It's about doing.

[Structure of the Invention] (Means for Solving the Problems) The present invention for solving the above problems includes an operation section having at least a character key, an edit key, and a cursor key, and a method for inputting information from these operation sections or an appropriate input section. an original text storage unit that stores an original text to be translated; a translation dictionary unit that stores knowledge information used in translation processing; and a translator that executes translation processing of the input original text using the contents of the translation dictionary unit. a translation storage unit that stores the translation obtained by the translation unit;
In a machine translation system comprising: a display unit for displaying the original text and the translated text; and an editing control unit for editing the original text or the translated text displayed on the display unit, When it comes to language, what articles should be generated?
Alternatively, the present invention is characterized in that a condition storage unit is provided to store an article condition, such as whether the article is no article, and the article condition can be arbitrarily set via the operation unit.

Second, when English is the second language, a condition storage unit is provided to store compound modifier conditions such as whether to connect the words of the compound modifier with a hyphen or to insert a blank between the words, The present invention is characterized in that the compound modifier condition can be arbitrarily set via the operation section.

Thirdly, when Japanese is the first language and English is the second language, it is important to know whether to use the English noun phrase expression or the gerund phrase expression for the Japanese proverbial noun. The present invention is characterized in that a condition storage unit is provided to store a s-sound noun condition, and the ss-ssss noun condition can be arbitrarily set via the operation unit.

Fourth, when Japanese is the first language and English is the second language, the translation conditions for how to express sentences that end in Japanese with "To do..." in English. The present invention is characterized in that a condition storage section for storing the translation conditions is provided, and the translation conditions can be arbitrarily set via the operation section.

Each of the first to fourth conditions can be arbitrarily set for one or a plurality of conditions in an appropriate combination.

(Function) The machine translation system of the present invention is provided with a condition setting section as described above, and each condition setting section has the following information: ■ When English is used as a second language, which article to generate or whether to use no article? Article conditions, ■ Compound modifier conditions such as connecting the words of a compound modifier with a hyphen or putting a blank between words when English is the second language, ■ Compound modifier conditions when Japanese is the first language and English is the first language. When using Japanese as a second language, there are two conditions: Japanese is used as a noun phrase in English, or as a gerund phrase. When using English as a second language, you can individually set the translation conditions for how to express Japanese sentences that end with "To do..." in English. The user can change the default processing when generating English articles, how to translate compound modifiers in noun phrases, how to translate strange nouns, and how to translate sentences that end with "to...". This can be easily and selectively specified, and appropriate translation results can be obtained without re-editing by the user's specification according to the document.

(Embodiment) FIG. 1 is a block diagram showing the overall configuration of a machine translation system according to an embodiment of the present invention. This system includes a keyboard 1 as an operation unit, an original text storage unit 2 that stores original texts input from the keyboard 1 or an input unit such as a communication device (not shown), a translation storage unit 3 that stores translated texts, and controls the entire system. an editing control section 4 that executes translation processing, a translation section 5 that executes translation processing, a translation expression specification control section 6 that controls processing related to selection and specification of translation expressions and controls processing in the translation section 5, and knowledge used in translation processing. It is comprised of a translation dictionary 7 that stores information, a display control unit 8 that controls the display of the original text, translated text, etc., a display unit 9, and a printing unit 10 that cleans the original text, translated text, etc. and outputs it as a hard copy. ing. Furthermore, in this example, a translation condition storage section 11 is particularly provided, so that conditions can be set as appropriate using the keyboard 1 and display section 9.

As shown in FIG. 2, the keyboard 1 has character keys 12 for inputting original text such as Japanese or English on its operation surface;
Translation instruction key 13 and document deletion.

Edit keys 14 to 19 for issuing commands such as connection, function keys 20 to 27 for operating various functions, cursor movement key 28 within the film, and other cursor control keys 29, 30 as appropriate. .31...

FIG. 3 is an explanatory diagram showing an example of the layout of the screen 9A of the display section 9. The input original text is in the original text display area A1 on the left side of the screen.
will be displayed. The translated text obtained as a result of the translation process is displayed in the translated text display area A2 on the right side of the screen at a position corresponding to the original text. Furthermore, an editing area 3 is provided at the top of the screen for displaying information necessary for various editing.

FIG. 4 is a flowchart showing an example of the flow of dialog translation processing by the editing control unit 4.

In the interactive translation process, the operator can input the original text and edit the corresponding translated text as appropriate.

In FIG. 4, the editing control unit 4 performs steps 401 to 40.
5, by inputting some key from keyboard 1,
Alternatively, it monitors whether a translation completion signal is received from the translation unit 5, and performs corresponding processing if there is any key input.

When the operator operates any of the function keys 20 to 27..., this is detected in step 405, and the process corresponding to the function key is performed in step 406.

Further, when the operator operates any of the edit keys 14 to 19, this is detected in step 404, and the process corresponding to the edit key is performed in step 407.

When the operator operates the cursor key 28 or other control keys, in step 408 processing for moving the cursor and other processing corresponding to the key operation are performed.

Further, when the operator operates the character keys 12 to input, for example, a Japanese sentence as the original text, each character key 12 is detected in step 403, and then the corresponding character code is sequentially displayed in the editing control unit 4 in step 409. set in the input buffer that is not used.

This input original text is displayed in the original text display area A1 of the display section 9 via the display control section 8 in step 410.

When the operator presses the translation instruction key 13 at any time, for example, when inputting the - sentence, step 40
This key is detected in step 2, and the editing control unit 4 supplies the original text in the input buffer to the translation unit 5, and instructs the start of translation processing in step 411. If you need to edit the input such as correction, insertion, or deletion while inputting the original text, press the cursor key 2.
After moving the cursor to the desired editing location using 8, this can be done using editing keys such as the insert key 14 and the delete key 15.

When the editing control section 4 detects a translation completion signal from the translation section 5 in step 401, the process proceeds to step 412, where it sends the translation candidates and auxiliary information obtained from the translation section 5 to the display control section 8 to display the translation.

The display control unit 8 displays the translation candidate at a position corresponding to the input original text in the translation display area A2, and if there is auxiliary information, the translated word is highlighted with high brightness or inversion, so that the operator can is made so that it can be identified. From this state, if any of the editing keys 14 to 19 is pressed, the editing control unit 4 detects this in step 404, and in step 407, presses each key for the word or phrase indicated by the cursor at this time. Perform the corresponding editing process.

In the editing process, for example, by operating the insert key 14, a character is inserted before the cursor position. By operating the delete key 15, the character string in the range indicated by the cursor is deleted. By operating the movement key 16, the range indicated by the cursor is moved.

By operating the cancel key 17, the above keys 14, 15° 16
negates the effect of Modifications are made using auxiliary information by operating the key 18, and other modification candidates for the word or phrase indicated by the cursor are displayed.

In addition, the following functions can be realized using the function keys.

By operating the translated word display key 20, the translated word can be displayed for each word in the translated sentence. By operating the dictionary display key 21, a dictionary can be displayed for a word in the original text.

By operating the dictionary registration key 22, new words and phrases can be registered. By operating the dictionary deletion key 23, words and phrases registered in the dictionary can be deleted. By operating the partial translation key 24, when translation fails, the partial translation is displayed. Further, as cursor keys, cursor movement keys 28 for moving the cursor in each direction,
Unit switching key 29 for switching the unit in which the cursor moves
, an inter-area movement key 30 for moving the cursor between display areas, and an enlargement/reduction key 31 for reducing the size of the cursor in units of characters or in units of words. Therefore, the operator can interactively obtain a translated text while inputting the original text and editing the translated text as appropriate.

In the machine translation system configured as described above, in this example, for example, in Japanese-English translation, the default processing when generating English articles, the method of translating compound modifiers in noun phrases,
The system selects and specifies the process that the system should take from among the variations regarding the translation form of ``sunoun'' and the translated expression of sentences ending in ``...'', and controls the translation process accordingly. It is configured as follows.

That is, in the machine translation system of this example, the selection and designation of various translation expressions for each of the above-mentioned translation expression methods is performed before starting translation of a certain document, and then the translation procedure is performed.

Figures 5 to 8 show the default processing when generating English articles, how to translate compound modifiers in noun phrases, the form of translation of s-modifier nouns, and when the phrase is "to do...". FIG. 6 is an explanatory diagram showing an example of a screen configuration that prompts selection and designation of a process to be set in the system from among variations of translated expressions of ending sentences.

When the user specifies a document to be translated, the translation expression specification control section 6 displays the information shown in FIGS. 5, 6, 7, and 8 on the display section 9 via the editing control section 4 and display control section 8. Double-sided 9B, 9C, 9D, and 9E are displayed to prompt such a designation. When there is a user's specification input from the keyboard 1, the content is first passed to the translation expression specification control unit 6 via the editing control unit 4, and then passed to the translation unit 5 according to the specification of the translation expression specification control unit 6. .

Here, in this example, a translation condition storage unit 11 is provided, and in each memory 1.1a, llb, llc, and lid, information is stored as to which article to generate or nothing when English is the second language. Article conditions for whether to use an article as an article, ■ If English is the second language, compound modifier conditions such as whether to connect the words of a compound modifier with a hyphen or a blank between words, ■ When one language is used as one language and English is the second language, there is a staggered noun condition that determines whether the Japanese stoop noun is expressed as a noun phrase or as a verb phrase in English. When using Japanese as the first language and English as the second language, the translation conditions for how to express a Japanese sentence ending in "To do..." in English are stored and set respectively. ing.

Therefore, these memories lla, llb, 11c, l
5 to 8 are displayed according to the stored contents of the id,
By making a selection using the keyboard 1, default contents are set in the translation expression designation control section 6.

FIG. 9 is a flowchart showing the flow of processing in the translation section 5. In the morphological analysis in step 901, the conjugation/inflection dictionary 7a is used in the input original text to convert words with changes in the ending, etc. into their original forms (basic forms).

In the dictionary search in step 902, the word/idiom dictionary 7b is searched for each word constituting the input original text to obtain information such as its part of speech and translation.

In the analysis control at step 903, a process of sending translation candidates to the next syntactic analysis is performed.

In the syntactic analysis in step 904, the structure of the original sentence is analyzed using the analysis grammar 7C, and the conceptual structure of the Japanese sentence is generated. If the analysis fails, proceed to step 9 via step 905.
Return to analysis control in 03.

The structure conversion in step 906 uses the conversion grammar 7d,
Converting Japanese conceptual structure to English conceptual structure. Here, if the translation expression specification control unit 6 sends the user specification contents regarding the translation form of the Su-modular noun and the translation expression of the sentence ending with "...to do", then according to the specification. Performs structural conversion processing. If rejected, the process returns to step 904 for parsing via step 907.

Syntax generation in step 908 determines the word order of the English surface sentence from the English conceptual structure according to the generative grammar 7e, and converts it into a word string. Here, the translation expression specification control unit 6
If user specifications regarding default processing when generating English articles and how to translate compound modifiers in noun phrases are sent, article generation can be controlled according to those specifications, and compound modifiers can be translated according to the specifications. Decide how to translate a word.

In the morpheme generation in step 909, the translated sentence is completed by changing the form of the word using the morpheme generation grammar 7f.

In each of the above processes, a signal is output to the editing control section 4 at the time of starting the process.

In this way, by specifying various translation expressions according to the document in advance, it is possible to obtain a translated text with the desired expression, which greatly reduces the need to re-edit the translation results. Editing efficiency is improved.

The present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof. Naturally, the options presented to the user may be other than those listed in the above embodiment.

[Effects of the Invention] As described above, since the present invention is a machine translation system as described in the claims, the user can adjust each item prepared by the system according to the type of document to be translated. By selecting and specifying the desired translation expression, appropriate translation results can be obtained without the need for re-editing.
