Abstract

PURPOSE:To perform the KANA (Japanese syllabary)/KANJI (Chinese character) conversion based on the correct paragraph punctuation information by analyzing an input character string to recognize the paragraphs and to display the punctuation of paragraphs and correcting the paragraph punctuation errors if detected. CONSTITUTION:The KANA character strings inputted from an input part 1 are successively sent to a paragraph recognizing part 2 where the punctuation of paragraphs recognized via a means applying the largest length coincidence method, etc. An input KANA character display part 4 displays the input character strings and the punctuation of paragraphs. If the punctuation of paragraphs has an error, this error is corrected by a paragraph punctuation correcting part 3 via a paragraph punctuation process carried out by an input operator. When the error is corrected, a KANA/KANJI conversion part 5 performs a KANA/KANJI conversion process based on the paragraph punctuation information. Then a conversion result display part 6 displays the result of the KANA/ KANJI conversion. As a result, the KANA/KANJI conversion is carried out based on the correct paragraph punctuation information.

Description

[Detailed Description of the Invention] [Object of the Invention] (Field of Industrial Application) The present invention relates to a kana-kanji conversion method for converting a character string expressed in kana to a sentence containing kanji and kana.

(Prior Art) Conventionally, methods for inputting kana character strings into a kana-kanji conversion device include a method of inputting the pronunciation for each kanji (single kanji conversion method), a method of inputting each clause (bunsetsu input conversion method), There is a method for inputting kana character strings (solid input method), regardless of kanji or bunsetsu. Of these, the solid input method has become mainstream in recent Japanese word processors.

This solid input method is convenient because there is no need to worry about kanji or phrases when inputting them. However, on the other hand, you can input a document without pressing the conversion key, so if you type for too long and make an input error, that part will be converted into unexpected kanji, so the mistake will be corrected on the display screen. The problem was that it was difficult to discover. Furthermore, since the text is converted sequentially without pressing a conversion key, there is a problem in that the person inputting the text has no way of knowing how the input sentence is being analyzed within the word processor.

(Problem to be solved by the invention) Although the solid input method that has been adopted in Japanese word processors in recent years is convenient, when inputting long documents, it is difficult to check the input characters later. If there is an input error, conversion is performed based on the incorrect input character string, and it is difficult to correct it.

In addition, it was unclear how the kana-kanji converter would divide the input hiragana character string into phrases, leaving the inputter feeling uneasy during conversion.

In view of this point, the present invention makes it easy to discover mistakes in the input Kana character string, and furthermore, if there is an error in the segmentation of the Kana-Kanji converter for the input Kana character string, it can be corrected before conversion. To provide a display correction method for the kana character string that can be corrected.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the kana-kanji conversion method of the present invention first sequentially analyzes input kana character strings and obtains the results from the analysis. It is characterized by explicitly displaying bunsetsu segmentation information by inserting blanks, slashes, or special bunsetsu segmentation codes into character strings.

Second, the present invention is characterized by having a means for changing the character string displayed by the means when the inputting person notices that the phrase is incorrectly cut.

(Function) According to the present invention, the inputter can accurately grasp in a short time whether or not the input characters are incorrect, and can also correct the errors if they are found.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is a kana input section, 2 is a phrase recognition section, 3 is a phrase cut correction section, 4 is an input kana character display section, 5 is an ephemeral kanji conversion section, and 6 is a conversion result display section.

The kana character strings input from the kana input section 1 are sequentially sent to the bunsetsu recognition section 2, and the bunsetsu cut is recognized by means such as longest-dispersion. The input kana character display section 4 displays the input character string and its phrase segment.

At this time, if an error occurs in the bunsetsu cutting, the bunsetsu cutting is corrected in the bunsetsu cutting correction section 3 after the bunsetsu cutting processing is performed by the inputter. Further, after the correction, the kana-kanji conversion section 5 performs kana-kanji conversion processing by making use of the phrase cut information, and the conversion result display section 6 displays the obtained results.

FIG. 2 is a flowchart of the phrase recognition section.

Every time you input a kana character, if bunsetsu can be cut after the input character in the part that is currently unconverted, set flag "1" and output the input character as is.If bunsetsu cut is not possible and flag= If it is 1, insert the bunsetsu cut code and output the input character, and
Let it be lag-0. It is impossible to cut bunsetsu and fla
When it is gmO, the input characters are output as they are.

Furthermore, when the user notices an error in the bunsetsu cut, the bunsetsu cut correction section recuts the bunsetsu. Repeat this operation sequentially until the number of input characters reaches the specified number of phrases, or ".

”, “,” is input, the kana-kanji conversion unit 5 performs kana-kanji conversion processing based on the segmentation.

FIG. 3 is a flowchart regarding the bunsetsu cut correction section. Activated by pressing the cursor key, bunsetsu segmentation key, or delete key. When the cursor key is pressed, the cursor is moved, and when the bunsetsu segmentation key is pressed, the bunsetsu segmentation code is inserted under the cursor, and it is deleted. If it is a key, the character under the cursor (including the bunsetsu separation code) is deleted.

FIG. 4 is an example of actually inputting "Please take off your footwear here." However, here it is assumed that the conversion starts when the number of phrases reaches three. The first letter ``
When you input koJ, ``ko'' is not a particle, so you cannot cut a phrase after ``ko''. Therefore, the flag remains at flag-0. The same goes for the next ``ko''. Since the next "de" is a particle and "koko" is one word, there is a possibility that a phrase will be cut after "de", resulting in flag-1. However, at the stage when "wa" is input, "de" becomes a particle, so there is a possibility that the sentence will be cut, and flag-1 will result.

However, when ``ki'' is input, ``ki'' is a - character and is not a particle, and even when combined with the previous character, it does not become a particle, so it becomes impossible to break a clause after ``ki'', and f
Since it is lag-1, phrase break occurs before "ki". Therefore, the display becomes 4-4.

The following processing is sequentially performed in the same way up to 4-6. However, the bunsetsu cut shown in 4-6 is different from the desired bunsetsu cut, ``Please take off your shoes here.''

Here, move the cursor to the phrase-cutting code between "ha" and "ki" (4-7) and press the delete key to delete the phrase-cutting code (
4-8). Also, move the cursor over “wa” (4
-9) Insert a phrase segmentation code by pressing the phrase segmentation key (4-10).

Then, if the cursor is returned to the human key (4-11), the continuation can be input, and when "<" is input, three clauses are recognized, so it is automatically converted (4-12). After that, ``.''
Performs the conversion when input, and obtains the final conversion result (
4-13). Furthermore, in a case like this example, the same effect can be obtained by moving the bunsetsu cut code using the movement key.

[Effects of the Invention] As described above, according to the present invention, in solid writing conversion, the user can perform input work while easily determining whether or not the input Kana character string is correct. In addition, the word processor's bunsetsu cut for the input character string is explicitly shown, so if it is different from what the inputter expects, the word processor can correct the bunsetsu cut and convert based on the correct bunsetsu cut information. It becomes possible to do so. Also,
Input errors can be easily detected and corrected before the input string is converted.
