Abstract

PURPOSE:To improve an analytical method for composite words in a machine translator. CONSTITUTION:An original analyzing part 1-1 analyzes the grammatical structure or meaning relation of an original based upon the information of a translating dictionary 1-4 and transfers the analyzed result to a composite word processing part 1-2. The processing part 1-2 refers to the contents of a dictionary and the analyzed result, and at the time of judging a composite word, executes the processing of the composite word and transfers the processed result to a translated sentence forming part 1-3. The forming part 1-3 outputs a translated sentence matched with the grammer of output side language based upon the analytical result obtained from the processing part 1-2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a machine translation device for translating a sentence written in a natural language into another natural language. The present invention relates to a machine translation device that can obtain a translated text of higher quality by eliminating the harmful effects of registration.

[0002]

2. Description of the Related Art In the current technology of machine translation, when a compound word is not registered in a dictionary, it is often difficult to select a translated word or the translation becomes awkward. However, when a compound word is registered in the dictionary, when a character string that matches the character string appears in the original sentence, the compound word is always prioritized in the dictionary. Therefore, there are cases in which the analysis of the input sentence fails because the words that should originally be dictionary-divided separately are dictionary-divided. For example, "high s
It is assumed that a compound word composed of the adjective "peed" and a noun is registered in the dictionary as a noun with the translated word "high speed". When the original text is "high speed system", it becomes "high speed system" and can be translated well, but the original text is "ve
In the case of “ry high speed system”, the adverb “very” has the property of modifying only adjectives, and thus cannot be translated well. In this case, if the compound word is deleted from the dictionary, "ve
"ry" can be translated successfully because it can modify the adjective "high", but then "high speed"
The translated word "high speed" in "d system" cannot be obtained.

[0003]

In the conventional machine translation device, when the input sentence analysis fails due to the dictionary lookup of the words that should originally be dictionary lookups as compound words,
The user can either modify the source text, delete the compound dictionary,
There is a disadvantage that there is no way to get the correct translation except to specify the word cut, and it takes time and effort to correct it.

[0004]

A machine translation apparatus of the present invention is a machine translation apparatus that analyzes a language and translates it into another language. The condition for becoming a compound word and a compound word and the condition are satisfied. A dictionary describing the processing method of the compound word in the case of being processed, and analyzing means for analyzing the grammatical structure, meaning, etc. of the input sentence using the dictionary, and the compound word in the dictionary from the analyzed sentence. A compound word processing unit that processes the compound word detected by referring to a condition according to the processing method, and a translation sentence generation unit that generates a translated sentence from the sentence processed by the compound word processing unit. ..

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
The present invention includes an original sentence analysis unit 1-1, a compound word processing unit 1-2, a translated sentence generation unit 1-3, and a translation dictionary 1-4.

The original sentence analysis unit 1-1 analyzes the grammatical structure and the semantic relationship of the original sentence 1-01 based on the information of the translation dictionary 1-4, and the result is sent to the compound word processing unit 1-2. I will give you. The compound word processing unit refers to the dictionary contents and the analysis result, processes the compound word when it judges that it is a compound word, and outputs the result to the translation generation unit 1.
-3. The translation generation unit 1-3 uses the analysis result obtained from the compound word processing unit 1-2 to translate the translation 1 according to the grammar of the output language.
Output -25.

FIG. 2 shows the flow of translation when using the present invention. First, the original sentence 1-01 is input and passed to the original sentence analysis unit 1-1 (2-1). The source sentence analysis unit 1-1 analyzes the source sentence by referring to the translation dictionary 1-4,
The analysis result is passed to the compound word processing unit 1-2 (2-2). The compound word processing unit 1-2 refers to the translation dictionary 1-4,
If the compound word information is described in the word, it is judged whether or not the condition is met (2-4). If they match, the processing described in the dictionary as a compound word is performed (2-
5). The result is output as a translated sentence to the translated sentence generation unit 1-3 (2-6). If they do not match, the result is output as a normal word as it is to the translated text generation unit 1-3, and the translated text is output (2-6).

A specific example will be described. It is assumed that the translation is from English to Japanese and the information of the compound word "high speed" is described in the dictionary of "speed". A plurality of translated words are described in the dictionary as shown in FIG. No condition is described in the first translation, and this translation is the normal translation. The condition for becoming a compound word is described in the second translated word, and only when this condition is met, the original sentence analysis unit selects the translated word and performs the process as the compound word.

The original text is "very high speed"
In the case of “system”, the condition 1 of the translated word “high speed” is satisfied, but the condition 2 is not satisfied, so “speed” is selected as the translated word, and finally the translated sentence “very "High speed system" is obtained.

The original sentence is "high speed system".
In the case of "em", since the conditions 1 and 2 of the translated word "high speed" are satisfied, "high speed" is selected as the translated word. At this time, the processing when a compound word is described in the dictionary is performed and the information of "high" is deleted. This is because he includes the meaning of "high" in the translated word "high speed." In this way the final translation "High speed system"
Is obtained. Finally, the analysis result after the compound word processing is passed to the translated sentence generation unit 1-3 to generate a translated sentence (2-6).

[0012]

As described above, according to the present invention, by improving the dictionary registration of a compound word and the analysis method thereof in the machine translation device, it is possible to correct the word without the user cutting the word and correcting the translated sentence. It is possible to generate a translated sentence, save the trouble of correction, and improve the translation efficiency.
