Abstract

PURPOSE:To suitably execute KANA (Japanese syllabary)/KANJI (Chinese character) conversion even when a parenthesis exists by processing a character after the front parenthesis symbol in the same way as the input character from a sentence head and processing the character after a rear parenthesis as the continuation of the character before the front parenthesis. CONSTITUTION:When a character is inputted from a keyboard 2, it is judged whether or not it is a front parenthesis, and at the time of the front parenthesis, the word information inputted early is transferred to a temporary storing part 25 of a converting processing part 6. Thus, the character inputted thereafter is processed in the same way as the character to start from the character head. Next, it is judged whether or not the rear parenthesis is obtained, and at the time of the rear parenthesis, the inputted character is converted and after the completion, the word information stored in the temporary storing part 25 is returned to a storing part. Thus, the character in continuation to the rear parenthesis is processed as the continuation of the character before the front parenthesis.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a kana-kanji conversion device, and more particularly, to a kana-kanji conversion device that compares input kana with the previous word every predetermined number of times and converts it into kanji. .

(Prior Art) Kana-Kanji conversion devices are used in Japanese input devices such as Japanese word processors, and so-called solid input Kana-Kanji conversion devices are often used because they allow easy input operations by operators.

Conventionally, in such a kana-kanji conversion device that uses solid writing input, when a predetermined number of characters are input from the first character, the input kana characters are converted into kanji, and the conversion is performed while sequentially comparing each predetermined number of characters with the previous word. Convert it to kanji. If a phrase, comma, etc. that indicates a break in the sentence is inserted in the middle, the conversion to kanji is performed even if the predetermined number of characters has not been reached.

(Problem to be solved by the invention) However, in such conventional kana-kanji conversion devices, input characters are converted into kanji while comparing each predetermined number of characters with the previous word, and periods and commas are , even if the number of input characters did not reach a predetermined number, Kana-Kanji conversion was performed, so even if parentheses were input, they were evaluated and converted in the same way as Kana characters. Therefore, there was a problem in that input characters inside and outside the parentheses were evaluated as continuous characters, resulting in kana-kanji conversion that was not appropriate for the text.

To solve this problem, it may be possible to convert parentheses into kana-kanji characters by interpreting them as text delimiters, but if the parentheses are considered to be text delimiters and processed, the pairs of front and rear parentheses will be converted. The sentences before and after the parentheses are converted into kana-kanji without any connection, and there is no connection between the sentences. However, normally, the sentences before and after the parentheses have a certain textual connection, If this is determined to be a break in a sentence, a problem arises in that appropriate kana-kanji conversion cannot be performed.

(Purpose of the Invention) Therefore, in the present invention, when a front parenthesis symbol is detected, the following literary characters are processed in the same way as input characters from the beginning of the sentence, and when a pair of trailing parenthesis symbols are detected, the end of the sentence is processed. At the same time, by processing the input characters after the trailing parenthesis symbol as a continuation of the characters input before the front bracket symbol, the sentences inside the pair of parentheses are converted into kana-kanji as independent sentences, and The aim is to convert the characters input before and after the parentheses symbol into kana-kanji as continuous character input, and to appropriately convert the sentences inside the parentheses and the sentences before and after the parentheses.

(Structure of the Invention) In order to achieve the above object, the present invention detects front parenthesis symbols in a kana-kanji conversion device that converts input kana characters into kanji by comparing each predetermined number of kana characters with the previous word. Then, the input characters after the front parenthesis symbol are determined to be kana input from the beginning of the sentence and are converted to kana-kanji, and when a trailing parenthesis symbol that pairs with the core parenthesis symbol is detected, it is determined to be the end of the sentence and is converted to kana-kanji. This system is characterized in that the input character input after the symbol is converted into kana-kanji as a continuation character of the input character input before the core parenthesis symbol.

Hereinafter, the present invention will be specifically explained based on examples.

1 to 4 are diagrams showing one embodiment of the present invention.

In FIG. 1, 1 is a kana-kanji conversion device, and character codes and the like are inputted from a keyboard 2 to the kana-kanji conversion device l. The keyboard 2 is provided with character keys, symbol keys, numeric keys, function keys, etc., and character codes and the like are inputted by the operator's key operations. The character code entered on the keyboard 2 is inputted to the conversion processing unit 6 via the input/output interface 3, buffer 4 and driver 5, converted into characters by the conversion processing unit 6, and sent to the CRT which is the display unit via the CRT driver 7. (
Cathode Ray Tube) 8. In addition, on the keyboard 2, instructions such as hiragana input and conversion methods are performed by key operations, and conversion processing is performed in the conversion processing section 6 according to these instructions.Conversion to kanji in the conversion processing section 6 is performed using the dictionary 10 with the kanji DO 39. search for.

This is done by searching the dictionary 10 according to the reading of the kana character and reading out the kanji that matches the reading.

Character data that has been converted by the conversion processing unit 6 and whose reading has been determined by operating the keyboard 2 is transferred via the buffer 11 and the input/output interface 12 to a word processor or the like to which the Honkana-Kanji conversion device 1 is applied.

As shown in FIG. 2, the conversion processing section 6 includes a character code acquisition section 21, a conversion section 22, a dictionary search section 23, a previous word information storage section 24, and a simple word information-time storage section 25. , a character string storage section 26, and display data is output from the character string storage section 26 to a display section 27 composed of the CRT driver 7 and CRT 8.

The character code acquisition unit 21 receives the character code input from the driver 5 and converts the cocodo data into "kana" according to the conversion method instructed by the keyboard 2, such as kana conversion.
It also detects various symbol codes and converts them into symbols. In particular, the front parenthesis symbol, e.g. “(” [”
It detects and converts symbols such as ")" and ")", and outputs the detection results to the converter 22.

The conversion unit 22 converts the kana input from the character code acquisition unit 21 into kanji, and the character code acquisition unit 2
It is equipped with a reading buffer that stores the kana input from 1. When the number of kana characters input from the character code acquisition section 21 reaches a predetermined number, the conversion section 22 determines the reading of the input kana and instructs the dictionary search section 23 to search the dictionary 10. The dictionary 10 is searched according to instructions from the converter 22. The dictionary search unit 23 reads out the kanji corresponding to the reading from the dictionary 10 and outputs it to the conversion unit 22 . When the kanji information is input from the character code acquisition unit 21, the conversion unit 22 converts the word number, reading size, notation size,
Furthermore, learning values, part-of-speech codes, starting codes, etc. are created and stored in the previous word information storage unit 24, which is a word information buffer, and the previous word information storage unit 24 is used for single! ! The word number, which has a fixed number of bytes of information for one word, is the word number from the beginning in the word information buffer, and the reading size indicates the size of the word in the reading buffer. Also, the notation size is determined by the character string storage section 26 which is the notation buffer of the word.
The learning value shows the number of past selections, etc.

When the kanji corresponding to the kana reading is input from the dictionary search unit 23 in this way, the conversion unit 22 outputs the kanji data to the character string storage unit 26 which is a notation buffer, and the character string storage unit 26 outputs the kanji data to the display unit 27. That is, the kanji is displayed on the CRT 8 via the CRT driver 7. When this series of kana-kanji conversion processing is displayed formantly for each buffer, it is shown as shown in FIGS. 3(a), (b), and (c).

The previous word information storage unit (word information buffer) 24 stores word information for a predetermined number of words (for example, 2 to 3 words), and is sequentially updated as the number of input words increases.

When performing the kana-kanji conversion, the conversion unit 22 refers to word information such as the previous word and the word before the previous time stored in the previous word information storage unit 24, and performs the kanji conversion while evaluating the continuity with the previous word.

Further, when data indicating that a front parenthesis symbol has been detected is inputted from the character code acquisition unit 21, the conversion unit 22 converts all the previous word information stored in the previous word information storage unit 24 into simple word information - hour storage. 25 and stores it, and the previous word information storage section 24 is cleared. Character data input after this front parenthesis symbol (ie, kana) is processed in the same way as input from the beginning of the sentence. In other words, every time the number of characters input after the front parenthesis symbol reaches a predetermined number, 1@ next kana-kanji conversion is performed,
The previous word information is stored in the previous word information storage section 24. After that, when data indicating that a trailing parenthesis symbol has been detected is input from the character code acquisition unit 21, the ° conversion unit 22 converts the character data (kana) input before the trailing bracket symbol in the same manner as the end-of-sentence processing.
At the same time, all the previous word information stored in the previous word information storage section 24 is cleared, and the word information before the front parenthesis symbol stored in the simple word information-time storage section 25 is read out and the previous word information stored in the previous word information storage section 25 is read out. The word information is stored in the word information storage section 24. The conversion unit 22 performs kana-kanji conversion processing on the character data (kana) input after the back parenthesis symbol as a continuation of the word before the front parenthesis symbol, that is, converts the kana input after the back parenthesis symbol into kanji. At this time, the word information before the front parenthesis symbol stored in the previous word information storage section 24 is referred to and converted into a kanji character.

Next, the effect will be explained.

The present invention is characterized by processing when a parenthesis symbol is detected in kana-kanji conversion.

This kana-kanji conversion process will be explained below according to the flowchart shown in FIG.

First, when the character code acquisition unit 21 acquires the character code input from the keyboard 2 (step P), it converts it into a kana or symbol and outputs it to the character string storage unit 26.
Detect parentheses (steps Pg, P3)
, when the character code acquisition unit 21 does not detect a front parenthesis symbol, it determines whether or not to convert it into a kanji (step P4).
), when converting into kanji, the dictionary search unit 23 searches the dictionary 10 according to the input kana reading and converts into kanji (step Ps) - At this time, referring to the previous word information, First, select the appropriate kanji for the series. The selected kanji reading is stored in the character string storage section 26 (step P,) and displayed on the CRT 8 of the display section 27 (step pv).

In addition, whether or not to convert to kanji in step P4 depends on whether the number of input kana characters reaches a preset number of characters, whether a symbol indicating the end of a sentence such as a phrase or comma is input, or whether the operator converts using the keyboard 2. The judgment is made based on whether a key operation was performed to instruct.

When it is not time for conversion, the input characters and symbols are stored as kana or symbols in the character string storage section 26 and displayed on the CRT 8 of the display section 27 (step pt).

When the character code acquisition section 21 detects a front parenthesis symbol in step pt, first, the conversion section 22 converts the kana up to the front parenthesis symbol into kanji by referring to the previous word information in the previous word information storage section 24.Step P ), then all the previous word information in the previous word information storage section 24 is transferred to the simple word information-time storage section 25 to clear the previous word information storage section 24 (step P
9). Therefore, for kana input after the front parenthesis symbol, the processing shown in steps P to P7 is performed, that is, the same processing as for kana input from the beginning of the sentence.

Then, when detecting the trailing parenthesis symbol, step P, ),
Even if the predetermined number of kana characters input has not been reached, the kana-kanji conversion process is performed in the same way as at the end of a sentence (step P10), the previous word information storage section 24 is cleared, and the simple word information-hour storage section 2 is stored.
The word information before the front parenthesis symbol stored in step 5 is stored in the previous word information storage section 24 (step P+t), and the kanji converted to kana-kanji is stored in the character string storage section 26 (step P,), and the display section 27 is Display on CRT 8 (step P?).

Therefore, a pair of parentheses can be used to independently convert kana input into kana-kanji from the beginning of the sentence in the same way as kana input, and the text within the parentheses can be appropriately converted to kana-kanji.

Further, the kana input after the trailing parenthesis symbol is converted into kana-kanji according to steps P and P, and at this time, the previous word information stored in the previous word information storage section 24 is referred to for kana-kanji conversion.

Therefore, the sentence with the trailing parenthesis symbol can be converted into kana-kanji as a continuation of the front bracket symbol by referring to the sentence before the front bracket symbol, and the sentences before and after the parenthesis symbol can be properly converted into kana-kanji as a continuous sentence. be able to.

In addition, the same process is applied to sentences that contain duplicate parentheses, such as parentheses containing another parenthesis, and each pair of parentheses separates the sentence and refers to the sentences before and after it. When the character data thus converted into Kanji is determined by operating the keyboard 2, it is outputted via the buffer 11 and input/output interface 12 to a word processor (not shown) or the like.

In the above embodiment, when a front parenthesis symbol is detected, 1, the kana input before the front parenthesis symbol is first converted into kanji, and then the previous word information is transferred from the previous word information storage unit 24 to the simple word information - However, the present invention is not limited to this, and if a predetermined number of characters is reached even if a front parenthesis symbol is detected, or if a key operation instructing conversion is not performed, the conversion process to kanji is not performed. First, the reading data may be temporarily stored in another buffer, and the previous word information in the previous word information storage section 24 may be transferred to the simple word information-time storage section 25. in this case,
When a trailing parenthesis symbol is detected, the reading data before the front bracket symbol is copied to the reading buffer, and the kana entered manually after the trailing bracket symbol is processed as a continuation of the kana before the front bracket symbol.

(Effects) According to the present invention, it is possible to convert a sentence within a pair of parentheses into kana-kanji as an independent sentence, and to convert characters input before and after the pair of parentheses into kana-kanji as continuous character input. Sentences inside parentheses and sentences before and after the parentheses can be appropriately converted into kana-kanji.
