DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine translator, and more particularly to a machine translator capable of selecting a correct translation without imposing a burden on a user.

[0002]

2. Description of the Related Art A problem in performing machine translation is as follows.
There may be multiple translations for one word. For example, the translation for Japanese “Haku” is v
omit, sweep, wear, and the like.

As described above, when a plurality of translations exist for one word, it has been conventionally performed to select a translation according to a co-occurrence condition (for example, Japanese Patent Laid-Open No.
No. 301869). For example, the word "haku" is selected as "SWEEP" for "waste garbage" and "WEAR" for "underwear". Case), a word related to the word, that is, a co-occurrence word (garbage and underwear in this example) which is a key of the co-occurrence condition, and a translated word (SWEE in this example)
(P, WEAR) is stored in the knowledge base, and an attempt is made to select a correct translation using the knowledge information for translation selection.

[0004]

However, conventionally, there is a problem in that the user has to register knowledge information for selecting a translated word in a knowledge base, which places a burden on the user.

An object of the present invention is to provide a machine translation apparatus capable of selecting a correct translation without putting a burden on a user.

[0006]

In order to achieve the above object, the present invention provides a knowledge base in which knowledge information for selecting a translation is stored, a dictionary in which grammar information and translation information are stored, and a content in the dictionary. An analyzer for analyzing the original sentence, an analysis result of the analyzer, the contents of the dictionary, the contents of the knowledge base, and when creating a translation based on the correction instruction,
For words whose translations are stored in the dictionary,
If the translated word can be specified based on the content of the knowledge base, a translation is generated using the translated word, and if the translated word cannot be specified based on the content of the knowledge base, a plurality of translations are stored in the dictionary. A translation device that selects one of the translations and generates a translation using the selected translation, and a knowledge base management device that manages the knowledge base. After the translation is generated by the generator and a correction instruction is given if necessary,
When shown is, after storing the knowledge base to generate knowledge information about the new shelf translation for selection on the basis of said analysis analysis results and translated sentences generated by the generating device of the apparatus, the new Translation selection knowledge inconsistent with translation selection knowledge

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. An input device 1, an analysis device 2, a generation device 3, an output device 4, a dictionary 5, a knowledge base 6, and a knowledge base management device And 7.

The input device 1 has a function of inputting an original text to be translated, a correction instruction, and an end instruction.

The analysis device 2 has a function of analyzing the original text, the correction instruction, and the end instruction input from the input device 1.

The generating device 3 translates the original sentence analyzed by the analyzing device 2 to generate a translated sentence, corrects the translated sentence according to the correction instruction, and sends the translated sentence to the knowledge base management device 7 according to the end instruction. Output function.

The output device 4 has a function of outputting the translation generated by the generation device 3.

The dictionary 5 stores grammatical information and translated word information necessary for analyzing an original sentence and generating a translated sentence.

The knowledge base 6 stores knowledge information for selecting a translation word.

The knowledge base management device 7 has a function of managing the knowledge base 6.

Next, the operation of this embodiment will be described.

When performing translation, a user inputs an original sentence from the input device 1.

When the original sentence is input from the input device 1, the analyzing unit 2 grammatically analyzes the original sentence based on the grammatical information stored in the dictionary 5, and obtains a connection relation of each word.

Now, for example, if the original sentence input from the input device 1 is "I wear garden garbage", the analysis result of the analysis device 2 is as shown in FIG. 2, for example.

The analysis result of the analysis device 2 is sent to the generation device 3 and the knowledge base management device 7.

When the analysis result of the original sentence is sent from the analysis device 2 to the generation device 3, the translation of each word in the analysis result is translated into the dictionary 5.
Is obtained by referring to.

When there is only one translation for each word in the analysis result obtained by referring to the dictionary 5, the generating device 3 performs translation using the translation obtained by referring to the dictionary 5.

When a plurality of translated words are obtained by referring to the dictionary 5 among the words in the analysis result, the generating device 3 determines the number of the translated words for each acquired word. All combinations of a word and another word in the analysis result are created. Thereafter, the generation device 3 passes the word from which the plurality of translations are obtained and a combination including the word to the knowledge base management device 7 and obtains a translation from the knowledge base 6 for the word from which the plurality of translations are obtained. To the knowledge base management device 7.

For example, as shown in FIG. 3, when there are words (haku, garbage) having a plurality of translations in the analysis result, "haku" and a combination thereof "i, haku", The "garbage, haku" and "garden, haku" are passed to the knowledge base management device 7, requesting that the translation of "haku" be extracted from the knowledge base 6, and the "garbage" and its combination " I, garbage "," haku, garbage ", and" garden, garbage "are passed to the knowledge base management device 7, and a request is made to extract a translation for" garbage "from the knowledge base 6.

When the above request is added from the generating device 3,
The knowledge base management device 7 searches the knowledge base 6 for a combination included in the request. When the combination is found, the translation registered in correspondence with the combination is notified to the generation device 3. When the combination is not found, the generation device 3 is notified that the translation is not registered.

When the knowledge base management device 7 notifies a translation for a word in which a plurality of translations are stored in the dictionary 5, the generation device 3 deletes the translation notified from the knowledge base management device 7. The translation is performed, and the translated sentence is output to the output device 4.

When the knowledge base management device 7 notifies that the translation is not registered, the generation device 3 translates using the translation acquired by referring to the dictionary 5. At this time, for a word having a plurality of translations, one of the plurality of translations is selected for translation.

When the translated sentence is output to the output device 4, the user needs to correct the translated sentence.
Input a correction instruction, and input an end instruction when there is no need for correction.

The correction instruction and the end instruction input from the input device 1 are sent to the generation device 3 via the analysis device 2.

When a correction instruction is input, the generating device 3 corrects the translated sentence in accordance with the input, and outputs the corrected translated sentence to the output device 4.

When an end instruction is input, the generating device 3 outputs a translated sentence to the knowledge base managing device 7.

When the translated sentence is sent from the generating device 3, the knowledge base managing device 7 decomposes the analysis result already sent from the analyzing device 2 into a combination of two words.
Further, a translation word corresponding to the combination is obtained from the translation sent from the generation device 3.

Thereafter, the knowledge base management device 7 stores the above-mentioned combination and the corresponding translation in the knowledge base 6.

Thereafter, the knowledge base management device 7 searches the knowledge base 6 for the same combination as the combination stored this time.

If the search is not completed, the process is terminated.

If the translation can be found, it is determined whether the translation corresponding to the combination found is the same as the translation corresponding to the combination registered this time, that is, the knowledge information for translation selection stored this time and the translation for selection of the searched translation. Is determined whether or not there is a contradiction in the knowledge information.

If it is determined that they are the same, one of them is deleted from the knowledge base 6, and then the processing is terminated. Also,
If it is determined that they are different, both are deleted from the knowledge base 6, and then the processing is terminated.

Now, for example, when the knowledge base 6 is in the initial state and no information is stored, the analysis result shown in FIG. Each word “I” in the analysis results based on the sentence,
The translations of “garden”, “garbage”, and “haku” are “I”,
"GARDEN", "GARBAGE", "SWEE
If it is determined to be "P", the knowledge base management device 7 first stores the contents shown in FIG. After that, the knowledge base management device 7
Search, the combination registered this time "I, Haku",
It is determined whether or not “garbage, foil” and “garden, foil” are already stored. In this case, since only the combination and the translation word stored this time are stored in the knowledge base 6,
The knowledge base management device 7 ends the processing. Therefore,
The contents of the knowledge base 6 are as shown in FIG.

Thereafter, it is assumed that the user has input an original sentence "I put on my underwear."

When the original text "I wear underwear." Is input, the analysis device 2 grammatically analyzes the original text based on the grammatical information stored in the dictionary 5 in the same manner as described above. Are passed to the generation device 3 and the knowledge base management device 7.

When the analysis result shown in FIG. 5 is sent from the analysis device 2, the generation device 3 acquires a translation of each word in the analysis result by referring to the dictionary 5.

Now, for example, it is assumed that the translated words shown in FIG. 6 are obtained for each word in the analysis result by referring to the dictionary 5.

The generating device 3 generates a plurality of translated words “SWEEP”,
Since the word “Haku” having “WEAR” and “VOMIT” exists in the analysis result, the word “Haku” from which a plurality of translated words are acquired and the combination “I, Ha” including the word “Haku” "Ku", "Underwear, Haku" to the knowledge base management unit 7,
It is requested that a translation for the word “Haku” be extracted from the knowledge base 6.

At this time, the contents of the knowledge base 6 are as shown in FIG. 4, and since the combination of "I, Haku" is stored in the knowledge base 6, the knowledge base management device 7 sets "I, Translated word “SWEE” corresponding to the combination of “Haku”
"P" is sent to the generation device 3 as a translation corresponding to the word "Haku".

The generation device 3 acquires the translation of the word “Haku” by referring to the dictionary 5 by referring to the dictionary 5 “SWEEP” passed from the knowledge base management device 7 and other translations of the words “I” and “underwear”. The translation is performed as “I” and “UNDEWEAR”, and the translation is output to the output device 4.

However, in the case of "I wear underwear."
Since the correct translation of “Haku” is “WEAR”, the user inputs a correction instruction from the input device 1 to instruct to correct “SWEEP” to “WEAR”.
This correction instruction is sent to the generation device 3 via the analysis device 2.

The generating device 3 corrects the translated sentence in accordance with the correction instruction, and outputs the corrected translated sentence to the output device 4.

When the user determines that the translated sentence output to the output device 4 is correct, the user inputs an end instruction.

The end instruction is sent to the generation device 3 via the analysis device 2, and when the end instruction is input, the generation device 3
The corrected translation (the translation obtained by correcting the translation of “Haku” into “WEAR”) is passed to the knowledge base management device 7.

When the corrected translation is sent from the generator 3, the knowledge base manager 7 converts the analysis result shown in FIG. 5 already sent from the analyzer 2 into a combination of two words. It is decomposed, and a translated word corresponding to the combination is obtained based on the translation sent from the generating device 3. After that, the knowledge base management device 7 stores the above combination and the corresponding translation in the knowledge base 6.

In the case of this example, the knowledge base management device 7 includes “I, Haku, I, WEAR”, “Underwear, Haku, UNDE”.
RWEAR, WEAR "," I, underwear, I, UNDER
WEAR "is stored in the knowledge base 6. As a result, the contents of the knowledge base 6 are as shown in FIG.

After that, the knowledge base management device 7 searches the knowledge base 6 and searches for the same combination as the combination "I, Haku", "Underwear, Haku", "I, Underwear" stored this time. In this example, since the combination of "I, Haku" is found, the knowledge base management apparatus 7 translates the translation corresponding to the found combination "I, Haku" and the combination "I, Haku" stored this time. It is determined whether or not the translated word corresponding to is identical, that is, whether or not the two pieces of knowledge information are inconsistent.

In this example, the translation corresponding to the combination "I, Haku" stored this time is "I, WEAR", and the translation corresponding to the found combination "I, Haku" is "I, SWEEP". , It is determined that the two pieces of knowledge information are inconsistent, and the two pieces of knowledge information are
Remove from.

As a result, the contents of the knowledge base 6 are as shown in FIG.

By repeating such processing, only the knowledge information for translation word selection including the co-occurrence word serving as a key for translation word selection remains in the knowledge base 6.
