Abstract

PURPOSE:To automatically correct and point out an error of a unisonal expression by inputting automatically the corresponding unisonal part, when the unisonal part does not exist in a sentence in which a unisonal adverb is used. CONSTITUTION:As for an input sentence, its sentence structure is analyzed by retrieving a Japanese language dictionary 5 in a sentence structure analyzing part 1. As for the input sentence whose sentence structure is derived, in a unisonal adverb searching part 2, whether a unisonal adverb exists or not is searched. If the unisonal adverb exists, the corresponding correct unisonal part is inputted by retrieving a unisonal adverb dictionary 6. In a comparing part 3, whether the unisonal part corresponding to the unisonal adverb in the input sentence and the unisonal part inputted by the unisonal adverb searching part 2 are the same or not is compared. When they are not the same, in a corrected sentence generating part 4, a sentence which has corrected the input sentence to a correct unisonal expression is generated, and also, a message of a unisonal expression error is outputted.

Description

[Detailed Description of the Invention] [Summary] This invention relates to a method for pointing out errors in vocative expressions in Japanese sentences and automatically correcting them to correct expressions.

The purpose is to point out errors in vocative expressions in Japanese input sentences and automatically correct them to correct expressions.

The present invention is configured to include a modified sentence generation unit that generates a sentence in which an input sentence is corrected into a correct conjugative expression.

[Industrial application field]

The present invention relates to a Japanese sentence processing ability formula, and particularly to a method for pointing out errors in phonological expressions in Japanese sentences and automatically correcting them to correct expressions.

(Conventional technology) There are many opportunities to write sentences in Japanese.

That's why it's difficult to create appropriate sentences.

An elaboration support system has been developed. The redaction support system is composed of 1 Japanese dictionary, 1 Japanese grammar dictionary, redaction knowledge, etc. 1. It redacts the created sentences and automatically corrects typos, etc.

Below is an example of automatic correction of inappropriate sentences by the elaboration support system.

Examples - Automatic correction/misprint Gradually → Gradually/Inappropriate term Ura-Nihon - Sea of Japan side/Punctuation I got it yesterday. Movies - Yesterday's movies and redundancies From 3cm or more to 5cffl -3
1 to 5C11・Bracket support I read this book (released in September)・Writing style
I had a day off yesterday, so I was late → ・・・・・・
I'm late/duplicate I fell off a horse/no leg sentences I think this paper is correct/denial of like I don't work like him/long strings Thank you very much/ambiguous If there is any damage/literary language I like it Whether you like it or not → don't like it/double negative It's not like you can't make it in time - you can make it in time/misuse You can see the effect → You can see the effect/Long sentence He did,..., and...・Old... did → He did... Then, stop using the combination Go to Tokyo and investigate - Go to Tokyo and then investigate - Collocation Translate by machine → Translate by machine - Unregistered word - Visited an oil field - Omitted Translate with ATLAS - Correspondence
The Movie I Saw Tomorrow - Co-occurrence The translation rate increases → becomes higher [Problem that the invention aims to solve] When a human composes a sentence in Japanese, "it's like a teacher."
You may create a sentence. but.

This sentence is bad sentence. This is because the adverb ``as if'' must correspond to ``it seems.'' Therefore, the above sentence is "just like a teacher."
The sentence must be corrected.

However, with conventional revision support systems.

As mentioned above, there is a problem in that it is not possible to point out incorrect vocative expressions.

SUMMARY OF THE INVENTION An object of the present invention is to provide a Japanese sentence processing method that can point out errors in vocative expressions in nine Japanese input sentences and automatically correct them to correct expressions.

[Means to solve the problem]

In order to achieve the above objects, 1) the Japanese text processing method of the present invention uses a revising processing system having a syntactic analysis unit that searches a Japanese dictionary to find the syntactic structure such as modification relationships of an input sentence; In a Japanese text processing method that points out errors in vocative expressions and automatically corrects them to correct expressions, it searches for the existence of vocative adverbs in the input sentence based on the results of the syntactic analysis unit, and If it exists, a vocative adverb search unit that searches the vocative adverb dictionary and retrieves the correct vocative part corresponding to the vocative adverb, and the vocative part of the input sentence corresponding to the vocative adverb and the vocative adverb that has been taken in by the vocative adverb search unit. A comparison section that compares the corresponding correct response section and the result of the comparison in the comparison section.

If the vocative part of the input sentence corresponding to the vocative adverb and the correct vocative part corresponding to the vocative adverb taken in by the vocative adverb search unit do not match, a corrected sentence generation unit that generates a sentence in which the input sentence is corrected to a correct vocative expression. The system is configured to provide the following.

FIG. 1 is a diagram explaining the principle of the present invention.

In the first II, 1 is a syntactic analysis unit, 2 is a vocative adverb search unit, 3 is a comparison unit 34 is a corrected sentence generation unit, 5 is a Japanese dictionary,
6 is a vocative adverb dictionary 6. The syntactic analysis unit 1 searches the Japanese dictionary 5 to find the syntactic structure of the input sentence.

The consonant adverb search unit 2 searches for the presence of a consonant adverb in the input based on the result of the syntactic analysis unit 1, and if the consonant adverb exists, searches the consonant adverb dictionary 6 to search for the consonant adverb. Retrieve the correct corresponding response part.

The comparison unit 3 compares whether the vocative part of the input sentence corresponding to the vocative adverb and the correct vocative part corresponding to the vocative adverb taken in by the vocative adverb search unit 2 are the same.

The corrected sentence generation unit 4 is the result of the comparison between the two comparison units 3.

The vocative part of the input sentence corresponding to the vocative adverb and the vocative adverb search unit 2
If the correct vocative part corresponding to the vocative adverb that has been imported does not match, a sentence is generated by correcting the input sentence to the correct vocative expression.

The Japanese dictionary 5 stores the notation of each word and its attribute information such as semantic attributes, 1 and grammatical attributes.

The vocative adverb dictionary 6 stores vocative adverbs and correct vocative parts corresponding thereto.

example) (choric adverb) (choric part) It looks like □ Nothing □ Not necessarily □ No full fever [Effect] The present invention will be explained in detail using a specific example.

First, it is assumed that the grammar ``He is like a teacher'' has been input.

After this input sentence is analyzed into morphemes, the syntactic structure is determined by searching the Japanese dictionary 5 in the syntactic analysis unit 1. In other words, a syntactic structure is required in which ``he is'' and ``maru'' are the dependencies of ``teacher da'', and ``teacher da'' is the subject of these terms.

The input sentence whose syntactic structure has been determined in the lateral sentence analysis section 1 is searched for in the vocative adverb searching section 2 to see whether or not a vocative adverb exists therein.

As a result, if the vocative adverb exists, the vocative adverb search unit 2 searches the vocative adverb dictionary 6 and retrieves the correct vocative that corresponds to the vocative adverb. Namely.

``Since j is a vocative adverb, the corresponding vocative part ``yoda'' is imported from the vocative adverb dictionary 6.

Then, the comparing unit 3 compares the vocative part corresponding to the vocative adverb in the five-person sentence and the correct vocative part corresponding to the vocative adverb taken in by the vocative adverb search unit 2 to see if they are the same. In other words, "Sensei da" and "Yoda" are compared.

As a result of the comparison in the comparing unit 3, if the vocative part in the input sentence corresponding to the vocative adverb in the input sentence and the correct vocative part corresponding to the vocative adverb taken in by the vocative adverb searching unit 2 do not match, the corrected sentence generating unit 4 In this step, a sentence is generated by correcting the human sentence into a correct conjugative expression, and the corrected sentence is output together with a message that the conjugative expression is incorrect. Namely.

The vocative expression is incorrect.

“He’s just like a teacher,” I correct.

A message is output like this.
