Abstract

PURPOSE:To simplify an editing operation by checking whether a single sentence of the corresponding 2nd language is translated or not and displays it after the success of analysis of the entire single sentence of the 1st language. CONSTITUTION:When an English sentence is supplied through an input part 1, a translation part 5 analyzes the input English sentence by means of a translation dictionary 6 to translate it into an equivalent Japanese sentence. Here the part 5 sends the information showing whether the English sentence is translated or not as a Japanese sentence to an editing control part 4. Thus the part 4 deletes (omits) the mark part (incl.., !, ?, etc.) at the end of the translation according to the information given from the part 5 and in case the English sentence is not translated as a Japanese sentence. Then a display part 8 displays both the original and the translation according to the indication of the part 4. While the period marks are omitted at the end of each translated sentence 74, 75 and 77 respectively since these sentences are obtained from each partial translation after the failure of analysis of the entire single original sentence. Thus a partially translated sentence can be immediately discriminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a machine translation system that suggests the type of translation to a user.

[Technical background of the invention and its problems]

In recent years, systems that automatically machine translate input original texts using computers have been attracting attention. This machine translation system basically divides the input original text into predetermined units of processing such as words (phrases) by morphologically and syntactically analyzing it, and searches a translation dictionary for each unit of processing. It is configured to find translated words (translations), etc., and combine them according to predetermined translation rules to obtain the translated text.

Such systems usually analyze a sentence in a first language, and if successful, translate it into a corresponding sentence in a second language. However, in the translation dictionary section, which is a finite storage device,
It is impossible to memorize all the translation information (linguistic information) of a language and a second language, and since humans have an infinite ability to create words, it is possible to successfully analyze all sentences in the first language. It cannot be translated into a single sentence in a second language. Also, the user (
It is also desirable to divide a sentence in a first language into semantic units and translate them into a second language according to the operator's wishes.

Therefore, there has been a desire for a child that can display the distinction of whether or not a sentence in the first language has been translated as a sentence in the second language (whether or not the length and body have been successfully analyzed).

[Purpose of the invention]

An object of the present invention is to provide a machine translation system that allows easy editing operations by an operator.

Another object of the invention is to convert one sentence in the first language into one sentence in the second language.
An object of the present invention is to provide a machine translation system that distinguishes whether or not a sentence has been translated.

[Summary of the invention]

In a machine translation system that translates a sentence in a first language into a sentence in a second language, this invention is based on whether or not a sentence in the first language is successfully analyzed and translated as a corresponding sentence in the second language. This feature is characterized by a distinguishing display of the following.

〔Effect of the invention〕

According to this invention, simply by checking whether all the translation information in the second language corresponding to one sentence in the first language has been output,
Level of translation (is a sentence in the first language translated as a sentence in the second language, or are each unit of meaning translated?)
It becomes possible to know.

Therefore, the percentage editing operation can be significantly simplified, and appropriate translation results can be easily obtained.

[Implementation sequence of the invention]

FIG. 1 is an overall block diagram of an English-Japanese machine translation system as an embodiment of the present invention. This system consists of an input section 11 consisting of a keyboard; an original text storage section 2 that stores English text input manually as the original text; Translation storage unit 3 that stores the Japanese text corresponding to the input English text as a translation; Editing leg unit 4 that controls the entire system; Translation unit 5 that executes translation processing; Translation unit that stores knowledge information used in translation processing; Dictionary 6. It is comprised of a display leg 7 for controlling the display of the original text, translated text, etc., a display section 8, and a printing section 9 for transcribing the original text, translated text, etc. and outputting it as a hard copy.

FIG. 2 is a diagram showing an example of the key layout of the input unit 1.

The input unit 1 is equipped with the following % bulls in addition to character keys for English characters.

Translation instruction keys: 100 Edit keys: 101-106 Function keys: 110-117 Cursor keys: 130-133 Other keys FIG. 3 is a diagram showing an example of the screen layout of the display unit 8. The input original text is displayed in the original text display area on the left side of the screen. The translated text obtained as a result of the translation process is displayed in the translated text display area on the right side of the screen at a position corresponding to the original text. Additionally, the editing area at the top of the screen can be used to display information necessary for various types of 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 and edit the corresponding translated text as appropriate. In steps 81 to S6, the editing control unit 4 monitors whether there is any key input from the input unit 1 or whether it has received a translation completion signal from the translation unit 5, and when there is some key input, perform the corresponding processing.

If the operator operates any of the function keys, this is detected in step S5, and the process corresponding to the function key is performed in step 812.

When the operator operates any of the edit keys, the operation is discarded in step S4, and the process corresponding to the edit key is performed in step 811.

When the operator operates the cursor key 130 or other control keys, processing for moving the cursor corresponding to the key operation and other processing are performed in step 813 via steps 81 to S6.

When the operator inputs the original text by operating the character keys, each character key is detected in step S3, and the corresponding character code is sequentially changed to (in the editing section 4).
(not shown) is set in the input buffer (step S
8). This input original text is displayed in the original text display area 4 of the display section 8 via the display rlfll cape section 7 (step S9).

When the operator presses the translation instruction key 100 at any time, for example, when he has finished inputting a sentence, the process proceeds to step S2.
When this key is detected, the editing inhibiting section 4 supplies the original text in the input buffer to the translation section 5 and instructs it to start translation processing (step 510). If you need a collection of input cursors for corrections, insertions, deletions, etc. while editing the original text, use the cursor keys to move the cursor to the desired editing location, and then use the edit keys such as the insert key 1011 and the delete key 102. You can do this with

FIG. 5 is a flowchart showing the flow of translation processing in the translation section 5. The translation unit 5 first searches the regular/irregular conversion dictionary 6a for the input original text, thereby converting words with changes in the ending etc. to their original forms (basic forms).

Next, the translation unit 5 first performs morphological analysis processing on the input original text using the regular/irregular conversion dictionary 6a (step 521
). Since the translation dictionary 6b stores information such as the translated word and its part of speech corresponding to each word, information such as the translated word and its part of speech is obtained for each word constituting the input original sentence. In step 823, the translation unit 5 uses the above information to find grammatically valid translation candidates. When deciding on this translation candidate.

In order to eliminate sequences that form combinations of non-consecutive part-of-speech sequences among all combinations of translations for each word found in step 822, the non-consecutive part-of-speech sequence rule dictionary 6
In step S24, the translation unit 5 uses C to obtain a plurality of grammatically correct translation word sequences as translation candidates.
to analyze the syntax of each translation candidate. That is, the translation dependency refers to the dictionary 6d, and if each translation word in each translation candidate has a modification candidate or polysemous word candidate, these are added as auxiliary information. When the above processing is completed, the translation section 5 outputs a translation completion signal to the editing sterilization section 4.

Again in FIG. 4, when the 1-edit bacteriostatic section 4 detects the translation completion signal in step S1, it proceeds to step S7, where it sends the translation candidate and auxiliary information obtained from the translation section 5 to the display control section 7 and displays the translated text. (step s7). The display control unit 7 displays the translation candidate at a position corresponding to the input original text (on the left side of the screen) in the translation display area, and displays the translated word in high f4 degrees or in reverse on the platform where the auxiliary information is located. This allows the operator to identify this fact.

If the 1 edit key is pressed from this state, 1 edit sterilization section 4
detects this in step S4, and performs editing processing corresponding to each key on the word or phrase indicated by the cursor at this time (step-11).

For example, by operating the insert key 101, a character is inserted before the cursor position.

By operating the delete key 102, the character string in the range indicated by the cursor is deleted.

By operating the movement key 103, the range indicated by the cursor is moved.

By operating the cancel key 104, the above keys 101, 102
．． Nullifies the effect of 103.

Modifications can be made using the auxiliary information by operating the key 105.
Other dependencies of the word/phrase pointed to by the cursor display candidates.

Note that the following functions can be realized using one function key.

By operating the translated word display key 110, the translated word can be displayed for each word in the translated sentence.

By operating the dictionary display key 111, a dictionary can be displayed for a word in the original text.

By operating the dictionary registration key 112, new words and phrases can be registered.

By operating the dictionary deletion key 113, words and phrases registered through dictionary registration can be deleted.

By operating the partial translation key 114, if the translation fails, the partial translation is displayed at run time.

The cursor keys include 130° cursor movement keys for moving the cursor in each direction, 131% unit switching keys for changing the unit in which the cursor moves, 131% inter-area movement keys 132 for moving the cursor between display areas.
It consists of enlargement/reduction keys to reduce the size of the cursor on a character-by-character basis or enlarge it on a word-by-word basis.

Therefore, the operator can interactively obtain a translated text while inputting the original text and editing the translated text as appropriate.

In the system configured as described above, further detailed explanation will be given of the display unit's processing to determine whether or not a sentence in the first language has been translated as a sentence in the second language.

FIG. 6 is a diagram showing a processing flowchart of the display control. An example will be described below in which the first language is English and the second language is Japanese.

First, an English sentence is input in the input section 1 of FIG. 1 (61 in FIG. 6). Then, the translation section 5 analyzes this English sentence using the dictionary dictionary 6 and translates it into the corresponding Japanese sentence (FIG. 6, 62). Here, the translation unit 5 sends information on whether or not one English sentence has been translated as one Japanese sentence (whether or not the analysis process for the English one-length body was successful) to the editing control unit 4 ( 6 (Fig. 63). According to this information, the editing control unit 4
If it is not translated as a single Japanese sentence, the symbol (,, l, 'i'...) at the end of this translated sentence will be deleted (minus (
1υ (omitted) (Fig. 6, 64). The display section 8 displays the original text and the translated text according to the instructions from the editing control section 4 (FIG. 6, 65). FIG. 7 is a diagram showing an example of the display screen, in which %5 corresponding original texts and translated texts are displayed in the original text display area 71 and the translated text display area 72. Among these, translated sentences 73 and 76 are the translated sentences obtained as a result of successful analysis of more than one sentence of the corresponding original sentences, and as usual, a period is added at the end of the sentence.

On the other hand, translated sentences 74, 75, and 77 fail to analyze the original sentence and are translated into partial units (word units or phrase units), so the period at the end of each sentence is omitted. There is. The main point for users is that these translations do not have periods.

At first glance, it can be seen that the translation is a partial translation unit.

Note that the present invention is not limited to the above embodiments. For example, one sentence in the first language may be translated as one sentence in the second language, and the symbol at the end of the sentence may be deleted just in case. Also, if the first language is Japanese and the second language is English, one sentence in the first language is translated as one sentence in the second language (if one is not translated, the beginning of the sentence in the second language may be lowercase). Furthermore, if the first language cannot be translated as a single sentence in the second language, the first language may be output as is.In short, the present invention can be implemented with various modifications without departing from the gist thereof.
