2. Description of the Related Art In recent years, techniques related to artificial intelligence have attracted attention, and many have been applied and put into practical use in various fields of industry. Among such artificial intelligence technologies, a machine translation device is one of the applications of natural language processing technology. (For example, Yoshiyuki Sakamoto "Translation environment and systemization technology" bit separate volume "Machine translation" p116-p127
Kyoritsu Publishing Reference) An example of the conventional machine translation apparatus described above will be described below with reference to the drawings.

FIG. 5 shows the configuration of a conventional machine translation device. An input unit 51 is for inputting a sentence in the first language to be translated, and generally a keyboard is used. A first language sentence analysis unit 52 analyzes the semantic structure of the sentence in the first language input from the input unit 51.

Reference numeral 53 denotes a semantic conversion unit which converts the semantic structure of the sentence of the first language analyzed by the first language analysis unit 52 into the semantic structure of the second language. A second language sentence generator 54 generates a sentence of the second language based on the semantic structure of the second language obtained by the meaning converter 53. A sentence display unit 55 displays the sentence of the second language generated by the second language sentence generation unit 54. Generally, a CRT or printer is used.

The operation of the machine translation apparatus configured as described above will be described below. First, when the operator inputs a sentence in the first language to be translated from the input unit 51, the first language sentence analysis unit 52 analyzes the sentence in the first language. Next, the meaning conversion unit 53
Converts the semantic structure of the sentence of the first language obtained as a result of the analysis of the first language sentence analysis unit 52 into the semantic structure of the second language. The second language sentence generation unit 54 uses the meaning conversion unit 53.
A sentence of the second language is generated based on the semantic structure of the second language obtained in. The sentence display unit 55 displays the result.

Further, depending on the machine translation device, when the translated sentence is corrected after translation, a translation replacement instruction is input,
In some cases, other translated word candidates are displayed and the operator selects a desired translated word from the candidates, so that the translation sentence can be corrected relatively easily.

[0007]

However, in the above-described conventional machine translation device, when translating into a second language having an article, the translation word in the sentence is replaced with another translation word after translation. In many cases, it was often necessary to replace the articles attached to the translated words by the translated word replacement. For this reason, the operator must judge the propriety of the article every time the translated word is replaced and correct the article, which is troublesome.

In view of the above-mentioned problems, the present invention also relates to an article which needs to be changed by the translation word replacement when the translation word replacement is performed for a certain word in the sentence of the second language having the article. (EN) Provided is a machine translation device capable of reducing the labor required for correction of a translated sentence by automatically replacing it.

[0009]

In order to achieve the above-mentioned object, the invention of claim 1 is a machine-machine translation device for translating a first language into a second language having an article. A translated word replacement instruction input means for instructing to replace the translated word with another translated word, and a translated word replacement means for replacing the translated word in accordance with an instruction given to the translated word replacement instruction input means, When the replacement is performed by the translation replacement unit, the article automatic replacement unit for correcting the article for the translation before replacement to an article according to the new translation is provided.

[0010]

According to the invention of claim 1, in the machine-machine translation device for translating the first language into the second language having an article, the translated word replacement instruction input means changes the translated word in the translated sentence to another word. Receive instructions to replace with the translation of.

The translated word replacement means replaces the translated word in accordance with the instruction given to the translated word replacement instruction inputting means. The automatic article replacement unit, when the replacement is performed by the translated word replacement unit, modifies the article for the translated word before replacement to an article according to the new translated word.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A machine translation apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of a machine translation device according to an embodiment of the present invention. Figure 1
In the figure, 11 is an input unit for inputting a sentence in the first language to be translated. For example, a keyboard or the like is used.

A first language sentence analysis unit 12 analyzes the semantic structure of the sentence of the first language input by the input unit 11. Reference numeral 13 denotes a semantic conversion unit that converts the semantic structure of the sentence of the first language obtained by the first language sentence analysis unit 12 into the semantic structure of the second language, and according to the semantic structure from a dictionary unit (not shown). The selected translation word is selected.

A second language sentence generator 14 generates a sentence in the second language based on the meaning structure and translated words of the second language obtained by the meaning converter 13. 15
Is a sentence display unit for displaying a sentence in the second language generated by the second language generation unit. Reference numeral 16 denotes a synonym storage unit, which holds translation word candidates other than those used to generate the second language when there are a plurality of translation words when the meaning conversion unit 13 selects translation words. ..

Reference numeral 17 denotes a translated word replacement instruction input unit, which replaces a translated word (hereinafter referred to as a replacement target word) in the sentence displayed by the sentence display unit 15 with another translated word (hereinafter referred to as an alternative word). In case of doing, the instruction is input. Reference numeral 18 is a synonym replacement unit, which searches for a replacement word from the translation candidate in the synonym storage unit 16 and replaces it according to an instruction from the replacement instruction input unit 17.

Reference numeral 19 denotes an article automatic replacement unit, which, when the synonym replacement unit 18 carries out translation word replacement, performs article replacement, addition or deletion for the translation word. The operation of the machine translation device configured as described above will be described with reference to FIGS. 2, 3, and 4, taking Japanese as the first language and English as the second language.

When a Japanese sentence to be translated is input from the input unit 11, the first language sentence analysis unit 12 analyzes the input Japanese sentence. The meaning conversion unit 13 converts the meaning structure of the Japanese sentence obtained by the analysis of the first language sentence analysis unit 12 into the meaning structure of the English sentence, and selects a translated word. At this time, if a synonym of the translated word exists, the synonymous word storage unit 16 holds the translated word other than that used for translation. next,
The second language sentence generation unit 14 generates an English sentence based on the semantic structure and the translated word of the English sentence obtained by the meaning conversion unit 13,
The generated English sentence is displayed on the sentence display unit 15.

Next, when the operator gives a translation word replacement instruction from the translation word replacement instruction input unit 17 to replace the replacement target word with an alternative word, the operation shown in FIG. 2 is performed. That is, when the synonym replacement unit 18 receives the translation replacement instruction, the synonym replacement unit 18 searches for an alternative word from the translation candidate stored in the synonym storage unit 16 (S1). If no alternative word is found there, the process ends. If there is an alternative word, the corresponding replacement target word in the sentence display unit 15 is replaced with the alternative word (S2), and then the article automatic replacement unit 19 is used.
Performs article replacement processing (S3). More specifically, this article replacement process is performed as shown in FIG.

First, the part of speech of the word to be replaced is a noun or an adjective +
It is determined whether the noun has any form (S1).
1). If the part of speech is other than that, the process ends. If it is a noun or adjective + noun,
First, it is determined what the article corresponding to the replacement target word is (S12). If the article corresponding to the word to be replaced is "the", it is judged whether or not the alternative word is a word having an article (S13), and if it is a word having an article, the article "the" is directly used. If the word is left without any article, "the" is deleted (S14), and the process is terminated.

If the article to be replaced is "the" in S12,
If it is determined that the replacement target word is not "a" or "
If the result of the determination is that the article to be replaced is "a" or "an", it is determined whether the alternative word is a word having an article (S16). If the word has no article, delete the current article (S
17). If it has an article, it is determined whether or not the word requires the exception processing of the article based on the table shown in FIG. 4 (S18). If it is determined to be an exception processing word, it is replaced with an appropriate article according to the table (S19). In the case of a word that is not an exception process, pay attention to the first letter of the alternative word (S20), set the article to "an" if the first letter is a vowel (S21), and set the article to "consonant" It is set to a "(S22).

Finally, when the word to be replaced is a word having no article, it is determined whether the alternative word has an article (S
23), if the word has an article, "the" is added as an article (S24), and if the word has no article, the process ends without doing anything. Although the input unit is a keyboard in the above embodiment, a storage device or the like may be used instead of the keyboard. The translation result may be stored in the storage device instead of being displayed.

Further, in the above embodiment, an example is shown in which the article replacement process is performed after the translation word replacement, but the article may be replaced at the same time as the translation word replacement.

[0023]

As described above, according to the present invention, by providing the synonym replacing means, the automatic article replacing means, etc., a certain word in the sentence of the second language is replaced with another translated word after the translation processing. When the translated word is replaced, the articles that need to be changed by the translated word replacement are automatically replaced, so that the labor required for correcting the translated sentence is significantly reduced.
