Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine translation system for analyzing a sentence in a first language and translating it into a sentence in a second language based on the sentence. The present invention relates to a machine translation system that can easily and accurately check items that cannot be uniquely determined from the language.

[0002]

2. Description of the Related Art In recent years, a machine translation system for automatically translating a first language into a second language using a computer has been receiving attention.
Moreover, it can be carried out efficiently and is expected to become more and more important in the future.

For example, when a Japanese sentence is translated into an English sentence by such a machine translation system, there is no information in the Japanese sentence and the sentence cannot be uniquely determined. However, there are some items that are indispensable for composing English sentences. For example, this is the article. This article has "a" and "the", but in order to create an accurate English sentence, it is necessary to properly use them in consideration of various conditions.

In such a case, the conventional machine translation system generates an article according to the set condition when the condition is set in the system itself, and the operator himself in advance when the condition is not set in the system itself. It was generating the articles set in the system.

For example, when translating Japanese "students study" into English, if the condition is not set in the system itself, the article that the operator has set in the system (for example, "the") Based on "The stud
ent studies. It was translated uniformly.

[0006]

However, it cannot be said that the articles generated as described above are always accurate. For example, the articles themselves set in the system by the operator are set based on the operator's intention. Although it is relatively accurate, it is not necessarily accurate, and the articles generated based on the conditions set in the system itself include the type of text to be translated, It may not always be appropriate in view of the degree of knowledge of the operator about the second language, English.

Therefore, the operator has to carefully check all articles translated as described above at the time of post-editing the translated text. Such a check operation is very complicated, and in particular, when it is unknown under what condition the article generated as a result of the translation is generated, there is a problem that the check operation becomes more complicated.

The present invention has been made in order to solve this problem, and it is a check condition corresponding to a plurality of translation conditions for translating an item of the second language that cannot be uniquely determined from the sentence of the first language. By setting, the above items can be checked efficiently with a simple operation according to the type of sentence to be translated, the degree of knowledge of the operator regarding the second language, etc. It is an object of the present invention to provide a machine translation system that enables efficient translation.

[0009]

To achieve this object, the present invention provides an input unit for inputting a sentence in a first language,
In a machine translation system having a translation unit that translates a sentence in a first language input from an input unit into a sentence in a second language, and a display unit that displays a sentence in a second language translated by the translation unit. When translating an item that cannot be uniquely determined by the translation unit among the items that compose a sentence in two languages, a translation condition setting unit that sets a plurality of translation conditions and a translation condition set by the translation condition setting unit are set. Generating means for generating the item based on the information, information giving means for giving information on the translation condition to the item generated by the generating means, and a check condition for setting a plurality of check conditions corresponding to each of the translation conditions The item is displayed on the display unit according to the information given by the information giving unit based on the check condition set by the setting unit and the check condition setting unit. It is configured to include a display control unit.

[0010]

In the present invention having the above-described structure, first, the text of the first language is input by the input unit, and the text of the first language is displayed on the display unit. Next, when translating the sentence of the first language into the sentence of the second language via the translation unit, a plurality of translation conditions are set for items that cannot be uniquely determined by the translation unit of the items constituting the sentence of the second language. It is set by the translation condition setting means.

After each of these translation conditions is displayed on the display unit, one translation condition is selected from the translation conditions via the selecting means. After that, the generation unit generates the item based on the translation condition selected by the selection unit, and the item is provided with information regarding the translation condition at the time of generation through the information provision unit.

Further, at the time of checking the items, the check conditions are set by the check condition setting means in correspondence with the respective translation conditions, and the display control means displays the items according to the information on the display unit based on the check conditions. To be done. Then, the operator checks the items displayed on the display unit according to the translation conditions and the check conditions corresponding thereto.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the drawings. For convenience of understanding and description of the invention, the first language which is a translated language is Japanese and the second language which is a translated language is English.

FIG. 1 is a block diagram schematically showing the configuration of the machine translation system of this embodiment. The system comprises an input unit 1 made of an input device such as a keyboard, a display unit 2 made of a display device such as a CRT, It is composed of a printing unit 3 including a printing device such as a scanning printer, and a data processing unit 4 that performs data processing for translating Japanese into English.

As shown in FIG. 1, the data processing section 4 further comprises an editing section 5, a translation section 6 and a dictionary section 7.

The editing unit 5 is for pre-editing sentences suitable for translating Japanese into English and for post-editing the translated English sentences into appropriate English, as shown in FIG. As described above, a translation condition setting unit 5A that sets a plurality of translation conditions to be described later for articles that cannot be uniquely translated into English from Japanese information, a display control unit 5B that displays the set translation conditions on the display unit 2, A translation condition selection unit 5C that selects a translation condition selected via the input unit 1 from the translation conditions displayed on the display unit 2 as a system, and a translation unit 6 and a dictionary based on the translation condition thus selected. A translation control unit 5D that executes translation through the unit 7 to generate an article, an information addition unit 5E that adds information about the selected translation condition to the generated article, and a plurality of check conditions corresponding to each of the translation conditions. Set up Check condition setting unit 5F to consists article display control unit 5G for displaying the article to the display unit 2 in accordance with information provided by the information assigning unit 5E based on check conditions described later.

The translation unit 6 executes a translation process from Japanese to English, and divides Japanese into words by a morphological analysis unit 8 and dictionary information for each word divided based on an analysis dictionary 13 described later. A syntax analysis unit 9 that analyzes the structure of Japanese while adding a sentence, a syntax conversion unit 10 that converts a word and a syntax from Japanese to English based on a conversion dictionary 14 described later, and a syntax conversion based on a generation dictionary 15 described later. A syntax generation unit 11 for generating a correct English syntax from the English converted by the unit 10.
And a morpheme generation unit 12 for generating a translation result sentence in English
Composed of and.

Further, the dictionary unit 7 stores an analysis dictionary 13 which stores information necessary for analyzing a Japanese structure, and information necessary for converting Japanese words and syntax into English. The conversion dictionary 14 and the generation dictionary 15 that stores information necessary for generating the English syntax from the English thus converted are provided.

Next, the operation of the machine translation system of this embodiment having the above configuration will be described. The Japanese sentence input from the input unit 1 is pre-edited by the editing unit 5 into a form suitable for translation into English, and then converted into morphological analysis information stored in the analysis dictionary 13 by the morphological analysis unit 8. It is divided into words based on. After that, the syntactic analysis unit 9 adds dictionary information to each word divided based on the syntactic analysis information in the analysis dictionary 13 and analyzes the Japanese syntax.

Then, in the syntax conversion unit 10, the Japanese words and the syntax are converted into English based on the conversion information stored in the conversion dictionary 14. As a result, the syntax generation unit 11 generates the correct English syntax based on the dictionary information stored in the generation dictionary 15 for the words and syntax converted into English as described above.

Here, taking an article as an example of an English item that cannot be uniquely determined from Japanese information, the control for generating such an article will be described with reference to FIG.

In FIG. 3, the operator corrects Japanese sentences input from the input unit 1 into the data processing unit 4 into Japanese suitable for translation into English in the editing unit 5, and first sets an article in S1. To do. In this way, the articles are set in advance in order to be able to generate articles according to the operator's intention even for words for which there is no article information in the conversion dictionary 14 and the generation dictionary 15 of the data processing unit 4. is there. Here, it is assumed that the operator has set the article "a".

Next, in S2, it is determined to what extent the article set by the operator in S1 is reflected in the translation result sentence. At this time, an option indicating the degree of reflection is displayed on the display unit 2 for use in the operator's judgment.

Here, the article generation section 11 of the translation section 6
In the case of generation by, the following three generation criteria (label 1 to label 3) can be considered.

(Label 1) First, for example, as shown in FIG. 5, when the article information stored in the generation dictionary 15 (for example, the definite article "the" is added immediately before the adjectives "same" and "following"). 6) to generate an article from the article information that is stored in the conversion dictionary 14 (for example, “ther information”).
When a bilingual English word is used in the meaning of a Japanese heading such as “right”, when the article to be used is always fixed, the article may be generated based on the determined article information). In these cases, the generated articles are all highly accurate.

(Label 2) Next, according to the condition of the syntax generator 11, article information for generating an article based on the conventional usage of English (for example, immediately after a preposition, such as "... in the box", or , "... the ca
This is a case where an article is generated based on definite article "the" often immediately before the antecedent of a relative clause such as "ke whileI made"). In this case, since there are exceptions, the accuracy of the generated article is lower than that in (1).

(Label 3) Finally, since there is no article information as described above regarding articles, the article is set based on the article information preset by the operator (for example, the article "a" set in S1). This is the case of generation. In this case, the accuracy of the articles generally generated depends on the English ability of the operator, but is lower than that in the case (2).

Considering the above-mentioned three article generation criteria, the following options are considered as options to be displayed on the display unit 2 in S2. A. The article generated based on the article information stored in the conversion dictionary 14 or the generation dictionary 15 is preferentially used,
For other articles, the articles set by the operator are used (corresponding to label 1). B. The articles generated based on the article information according to the conventional usage of English according to the condition of the syntax generation unit 11 are used, and the articles set by the operator are used for other articles (corresponding to label 2). .. C. The articles set by the operator are used as all articles (corresponding to label 3).

Option C is selected when the operator's English ability is extremely high or when special Japanese is translated, and option B is selected when the operator's English ability is relatively high or the translation result sentence It is selected when accuracy is required up to a relatively small portion, and option A is selected when the operator's English ability is low or the translation result sentence is not required to be very accurate.

The above three options are displayed on the display unit 2 in S2. When the operator selects option C in S2, the article "a" set by the operator in S3 is reflected in all articles, and "a" is generated for all articles.

When the operator selects the option A in S2, the process proceeds to S4, in which the articles set by the operator are the articles other than the articles generated based on the article information of the conversion dictionary 14 and the generation dictionary 15. This is reflected, and the article “a” set in S1 is generated for this article.

Further, if the operator selects option B in S2, the process proceeds to S5, in which the article set by the operator is based on the article information according to the conventional English usage according to the syntax generator 11. The articles other than the articles generated by the above are reflected, and the articles “a” set in S1 are generated for the articles. To each of the articles generated as described above, information (translation label information) relating to the translation condition that is used as a reference for generation of the articles by the information adding unit 5E is added.

S6 to S11 are flow charts of the article check program generated as described above. In S6, it is determined which label is used to display the generated article on the display unit 2. At this time, the display unit 2 displays three selection menus of label 1, label 2 and label 3 as check conditions.

When the operator selects label 1 in S6, the process proceeds to S7, and in S7 the display unit 2 distinguishes the article generated based on the article information of the conversion dictionary 14 and the generation dictionary 15 from other words. Highlight it. When the operator selects the label 2 in S6, the process proceeds to S8, and in S8, the article generated based on the condition of the syntax generation unit 11 is displayed in reverse on the display unit 2. Further, when the operator selects the label 3 in S6, the article preset by the operator in S9 is highlighted on the display unit 2.

Thereafter, after the translation result sentence is generated through the morpheme generation unit 12 and the translation is completed, in S10, at the time of post-editing, each article is checked by highlighting each article in S7, S8 or S9. Is performed, the post-editing is performed in S11 such as checking other items, and the translated sentence is printed through the printing unit 3.

As described in detail above, the machine translation system of the present embodiment, when translating Japanese into English, information (labels 1, 2) at the time of generating an article that cannot be uniquely determined from the information in Japanese. (Label information of 3) is added to the information adding unit 5
It is given to the article generated via E, and when checking the article, each label 1, 2, based on the label information,
Since it is displayed in reverse on the display unit 2 for each 3, the articles can be efficiently checked without omission according to the type of sentence to be translated, the degree of English ability of the operator, and the like. As a result, it is possible to reduce the work of checking articles and perform efficient translation.

In this embodiment, the generated article is displayed on the display unit 2.
When the label 1 is selected in S7, not only the article of the label 1 but also the label 2 and the label 3 are displayed according to each label selected by the operator. The belonging articles may be highlighted at the same time, and if the label 2 is selected in S8, the article of label 2 and the article of label 1 may be highlighted.

By controlling the display in this way, all articles whose accuracy is lower than the article of the selected label are displayed in reverse video, which is more flexible according to the sentence to be translated and the English ability of the operator. You can check articles. By controlling the display in this way, if high translation accuracy is required, label 1 can be selected and all articles can be highlighted and checked, and in other cases, label 3 can be selected. If so, only the articles set by the operator can be highlighted so that the articles can be checked efficiently.

[0039]

As described above, according to the present invention, it is possible to set check conditions corresponding to a plurality of translation conditions for translating an item in a second language that cannot be uniquely determined from a sentence in a first language. Depending on the type of sentence to be translated, the degree of knowledge of the operator regarding the second language, etc., the above items can be efficiently checked with a simple operation, thus reducing the check work and providing an efficient translation. It is possible to provide a possible machine translation system, and its industrial effect is great.
