Abstract

PURPOSE:To easily obtain the proper results of translations by adding a different interpretation key to the function keys of an input part in order to attain translation in plural ways of interpretation with simple constitution and also to simplify the editing operation of an operator. CONSTITUTION:An editing control part 4 detects the key input given from an input part 1 or the translation end signal sent from a translation part 5 and then displays the translated sentence candidates and the auxiliary information on a display part 8. In this case, a different interpretation key added to the function keys of the part 1 is operated as long as another different interpretation exists and another kind of interpretation is newly used for the second translation. In other words, an operator pushes the different interpretation key to obtain a different type of interpretation after looking at both an original sentence and its translated one displayed on the part 8. In such a case, the part 4 indicates the new interpretation to an analysis control part and the second translation is carried out via a series evolution table. Then the second translation is displayed on the part 8. Thus it is possible to perform the translation in plural kinds of interpretation and also to simplify the editing operations. Then the proper translation results are obtained.

Description

[Detailed description of the invention] 3. Detailed description of the invention [Purpose of the invention] (Field of industrial use) The present invention relates to a machine translation system.

(Prior Art) In recent years, systems that automatically machine translate input original texts using computers have been attracting attention.

This machine translation system basically analyzes the input original text by morphologically and syntactically, divides it into predetermined processing units such as words (f'i3), and searches the translation dictionary for each processing unit. It is configured to find translated words (translated phrases) and combine them according to predetermined translation rules to obtain the translated text.

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

Also, when analyzing the original text, if multiple interpretations are possible,
The system selected one of them, translated it, and provided the result to the operator.

For example, when the original text is in Japanese, there are expressions that can be interpreted in multiple ways, including the position of clause breaks, pronunciation, and part of speech.

The Japanese sentence ``I matched with the person in question.'' can be separated into two clauses: ``Today/the person'' or ``Now/1] the person,'' but the conventional system uses only one of these two. I chose one and translated it.

(Problems to be Solved by the Invention) In the machine translation system described above, the system translates only the interpretation that it considers optimal, provides the result to the operator, and rejects other interpretations. Therefore, if the interpretation was not what the operator expected, the operator had to either edit the translation into an appropriate translation, or rewrite the original text into a sentence that could only be interpreted clearly and then have it retranslated. In other words, in the example above, you could say, ``I just met a Japanese person.'' or ``I met a Japanese person today.''

” I had to rewrite the original text.

These operations are extremely troublesome and place a heavy burden on the operator.

The present invention provides a machine translation system that enables translation with a simple configuration and multiple interpretations, and at that time, simplifies editing operations by an operator and can easily obtain appropriate translation results. The purpose is to

[Structure of Pronunciation] (Means for Solving the Problems) In order to achieve the above object, the present invention includes an input section, and the original text inputted through the input section is divided into words and translated. a morphological analysis unit that parsimoniously searches a dictionary to examine the grammatical attributes of each word; and a syntax that examines the syntactic connection relationships of each word examined by the morphological analysis unit, extracts syntactically possible connection relationships, and stores them. an analysis unit, a structure conversion unit that examines case relationships from the connection relationship information extracted by the syntactic analysis unit and converts the case relationships into case relationships of the target language, and generates a translated sentence based on the case relationship information of the target language. a display unit that displays the original text and the translated text; and a display unit that displays the original text and the translated text; and when editing the translated text displayed on the display unit, when a different interpretation of the translated text is instructed via the input unit, the syntax analysis unit Provided is a machine translation system comprising: a separate interpretation control unit that selects other stored syntactic connection relationship information, sends this connection relationship information to the structure conversion unit, and prompts retranslation. do.

(Function) In the device configured as described above, when editing the translated text displayed on the display section, if a different interpretation of the translated text is instructed via the human power section, the different interpretation control section receives this instruction and Other syntactic connection relationship information stored in the syntactic analysis unit is selected, and this connection relationship information is sent to the structure conversion unit. The structure conversion unit examines case relations according to this connection relation information and changes the case relations to those of the target language. Then, the translation generation unit generates a translation based on the case relationship information of the eight target words.

In this way, the operator can easily obtain a different interpretation of the translated text.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure is an overall block diagram of a Japanese-English machine translation system that is an embodiment of the present invention. This system includes an input section 1 consisting of a keyboard, an original text storage section 2 that stores the human-written Japanese text as the original text, a translation storage section 3 that stores the English text corresponding to the human-written Japanese text as the translated text, and controls the entire system. an editing control section 4 that executes the translation process, a translation section 5 that executes the translation process, a translation dictionary 6 that stores knowledge information used in the translation process, a display control section 7 that controls the display of the original text, the translated text, etc., a display section 8, and the original text and the translated text. and a printing section 9 for confirming documents and outputting them as hard copies.

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

The input unit 1 is equipped with the following various keys in addition to the character keys for [1] Japanese language and literary skills.

Translation instruction key = 100 Edit key: 101-100 Function key: 110-118 Cursor key: 130-133 Other keys FIG. 3 is a diagram showing the layout of the screen of the display section 8. As shown in FIG.

The human 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 each insertion.

FIG. 4 is a flowchart showing the flow of dialog translation processing by the editing control section 4. In the interactive translation process, the operator can input the original text and edit and control the corresponding translated text as appropriate. In steps 81 to S5, the editing control unit 4 monitors whether there is any key input from the input unit 1 or whether a translation completion signal is received from the translation unit 5, and if there is any key input, Perform the corresponding processing.

If the operator operates any of the function keys, this is detected in step 5, and the process corresponding to the function key is performed in step S12.

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 S13 via steps s1 to S5. When the operator inputs the original text by operating the character keys, each character key is detected in step S3, and the corresponding character codes are sequentially set in the input buffer (not shown) in the editing control unit 4 (
Step S8). This human-written original text is displayed in the original text display area of the display unit 8 via the display control unit 7 (step S9).
. When the operator presses the translation instruction key 100 at any time, for example, when the human effort of the - sentence is completed, step S
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 it to start translation processing (step 5IO). If input editing such as correction, insertion, deletion, etc. is required during the original writing, move the cursor to the desired editing location using the cursor keys, and then use editing keys such as the insert key 101 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 clause analysis unit (S51) converts the input original text into clause units using the words obtained from the dictionary search unit (S52) and the adjunct connection/conjugation inflection dictionary 6a. The dictionary search unit (S52) searches the word dictionary 6b for words that can constitute the input original text. Information such as its part of speech and translation is also requested. Analysis control section (S53)
performs processing to send translation candidates to the syntax analysis section. The syntactic analysis unit (S54) uses the parsing grammar 6C to analyze the translation candidate hli.
parses the syntax of , and generates a structure that still contains semantic ambiguity in interpretation. If the analysis fails, the process returns to the analysis control section. The semantic analysis unit (S55) uses the semantic analysis grammar 6d to generate a Japanese structure that eliminates ambiguity in interpretation. The structure conversion unit (S56) converts the Japanese structure into an English structure using the conversion grammar 6e. If rejected,
Return to fM syntax analysis section. The syntax generation unit (S57) determines the English word order from the English structure according to the generative grammar 6f.
Convert to j-word string. The morpheme generation unit (958) completes the translated sentence by changing the ending of the word by +1 using the morpheme generation grammar 6g.

Each of the processing sections described below outputs a signal to the editing control section 4 at the time of starting processing.

Referring again to FIG. 4, when the editing control unit 4 detects the translation completion signal in step S1, the process proceeds to step S7, where it sends the translation candidates and auxiliary information obtained from the translation unit 5 to the display control unit 7 and displays the translated text. (Step S7). The display control unit 7 displays the translation candidate in the translation display area at a position corresponding to the input original text (on the left side of the screen), and if there is auxiliary information, displays the translation with high brightness or in reverse video so that the operator can It is made so that it can be identified.

From this state, when the edit key is pressed, the edit control unit 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 511). For example, insert key 10
Operation 1 inserts a character 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 effects of the keys 101, 102, and 103 are nullified. The modification is done by operating the key 105.
Using the auxiliary information, other modification candidates for the word or phrase pointed to by the cursor are displayed.

Note that the following functions can be realized using the function keys.

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 the word in the current sentence. New words and phrases can be registered by operating the dictionary display key 112. By operating the dictionary deletion key 113, words and phrases registered through dictionary registration can be deleted. Partial translation key 1
By the operation 14, when the translation fails, the partial translation is displayed. By operating the different interpretation key 115, if another interpretation exists, the translation can be performed again with a different interpretation from the one used when the translation was already performed.

Further, as cursor keys, cursor movement keys 130 move the cursor in each direction, and a unit switching key 131 moves the cursor (1'L position).
, an inter-area movement key 132 for moving the cursor between display areas, and an enlargement/reduction key 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 system configured as described above, another interpretation of editing processing will be described in detail with reference to the flowchart shown in FIG. First, when the operator looks at the original text and translated text displayed on the display section 8 and wants to give a different interpretation, presses the different interpretation key 115 (<601), then the editing control section 4 sends a message to the analysis control section (S53). Instruct another interpretation. The analysis control unit (S53) investigates the stored series development table (602).

Here, the sequence expansion table is stored in the analysis control unit (S53) and includes translation candidate information indicating possible syntactically conjunctive relations, and which translation candidates are particularly appropriate among the conjunctive relations that each translation candidate has. It consists of translation priority information indicating whether each translation candidate has already been translated, and a translated flag indicating whether each translation candidate has already been translated. The translated flag is set to "0" if it has not been translated, and "1" if it has been translated.

In step 602, the analysis control unit (S53) examines the series expansion table, and if there is an untranslated translation candidate (step 603
), sends the translation candidate with the highest priority among the untranslated candidates to the syntax analysis unit (S54), and prompts for retranslation (605)
. If retranslation fails, return to 602 (6 (16
). If there is no untranslated translation candidate in 603 and there is only one series (607), the analysis control unit (S
53) sends the information to the editing control section 4, and the editing control section 4 displays the message "There is no alternative interpretation h17" on the display section 8, and ends the alternative interpretation processing.

If all translation candidates have been translated in step 607, “
At the same time as displaying the message "All candidates have been translated", the analysis control unit (S53) clears the translated flag to 0 and ends the separate interpretation process (60g).

Hereinafter, the structure of the series development table and display screen in the separate interpretation process will be explained in detail using FIGS. 7 to 10. First, Figures 7 and 8 show the translation of the original sentence, ``The Buddha has now met the Japanese.'' When the original text is input, the phrase analysis section (S51) and the dictionary search section (S51)
Based on the information sent via 52), the analysis control unit (
In step S53), the series development table shown in FIG. 7 is created and stored.

Depending on the interpretation of the phrase breaks, the translation candidates are ``today/himself'',
There are two possibilities: ``now/Japanese''. Analysis control section (S
53) sends the one "Today/Principal" which is considered to be appropriate among these two translation candidates Mi to the parsing unit (S54) and sets the translated flag to "1".

Therefore, as shown in FIG. 8, the translated results based on this interpretation are shown (S81). Here, when the operator presses another interpretation key 115, the analysis control unit (S53
) sends the untranslated candidate "now/Japanese" in the series expansion table to the syntax analysis section (S54), and changes the translation section flag from "0" to "1".

Therefore, the translated results will be displayed based on this interpretation (
S82).

Next, FIGS. 9 and 10 show the translation of the original sentence "I went." There are two possible translation candidates: ``ita'' and ``okonatta'' depending on the interpretation of ``ita'' reading. The word ``ita'' with a higher priority is translated first (SIOI), and the candidate ``okatata'' is translated according to instructions for another interpretation (S102).

As described above, since the operator can obtain multiple translation results by simply pressing the different interpretation key 115, there is no need for the conventional work of rewriting the original text and retranslating it, and it is easy to obtain the appropriate translation results. You can get a translation.

[Effects of the Invention] According to the present invention, it is possible to perform translations with multiple interpretations, and when performing different interpretations, it is possible to simplify the operator's editing operations and easily obtain appropriate translation results. .
