Abstract

PURPOSE:To prevent a numeric string from being divided by punctuation mark, comma, and period in the numeric string by preventing a character string from dividing when numerics exist immediately before and after a punctuation mark. CONSTITUTION:A punctuation mark extracting means 3 retrieves a KANA (Japanese syllabary) string stored in a character string memory means 2, and extracts punctuation marks such as a comma and a period. An immediately before non-numeric deciding means 4 receives the position of the punctuation mark from the punctuation mark extracting means 3, and outputs a signal to an OR gate when the character immediately before the punctuation mark is not a numeric. An immediately after non-numeric deciding means 5 outputs a signal to the OR gate 6 when the character immediately after the punctuation mark is not numeric. When the signal is transmitted from the OR gate 6, a conversion unit reading means 7 receives the position of the punctuation mark from the punctuation mark extracting means 3, reads in the KANA string up to the position of the punctuation mark from the character string memory means 2, and outputs it to a KANA/KANJI (Chinese character) converting means 8.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is a method for automatically dividing character strings into multiple processing units, which is required as preprocessing for converting solid input from kana to kanji, etc. in a word processor or the like. It's about how to do it.

(Prior art and its problems) Conventionally, in word processors and the like, division of a kana character string input in solid writing into kana-kanji conversion processing units is sometimes performed using delimiters such as punctuation marks, commas, and periods. An example of this is shown below.

Kyoha, Yoitenkides.

1/Kyoha, lyoitenkides,! In this case, ``Kyoha'' and ``Yoitenkides'' will be converted into kana and kanji in two separate steps. In addition,
l'' is a signal indicating division.

However, this method of simply dividing by punctuation marks has the disadvantage that the number string is divided by punctuation marks, commas, and periods as shown below.

55% Datta J Although the result of Kana-Kanji conversion may not be an error, this division error is often fatal when performing calculations based on numerical values, reading together, etc. For example, in the above example, when reading together, if the number part is read aloud, the following erroneous reading will occur due to an error in division.

/nee, 'yuk l hahi yak... l rokujugo l gojugo... (Objective of the invention) An object of the present invention is to prevent a number string from being divided by a comma, comma, or period in the number string. , to provide a method that can correctly split strings.

(Structure of the Invention) When dividing a character string into a plurality of units, the present invention extracts delimiters such as commas, commas, and periods from the character string, and determines whether the characters before and after the delimiter are numbers. , and if there is no number immediately before or after the delimiter, divide the string using the delimiter, and if there are numbers immediately before or after the delimiter, do not divide the string using the delimiter. This is a string segmentation method featuring the following.

(Example) The configuration of the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram showing an embodiment of a Japanese literary device that embodies the character string division method of the present invention. 1st
In the figure, 1 is a character string input means, and a kana keyboard or the like is used to input a kana character string.

Reference numeral 2 denotes a character string storage means, which stores the kana character string inputted by the character string input means 1. magnetic disk device,
This can be realized using a magnetic tape device, IC memory, etc.

3 is a delimiter extracting means, which searches the kana character string stored in the character string storage means 2 and extracts period marks (.) and commas (,).
, a comma (1), a period (,), etc., and output the position of the extracted delimiter to the immediately preceding non-numeric determining means 4, immediately following non-numeric determining means 5, and conversion unit reading means 7.

4 is the immediately preceding non-numeric determining means, and the delimiter extracting means 3
The position of the delimiter is taken from , and it is determined whether the character immediately before the delimiter is a number.

A signal is output to the OR gate 6 when the character immediately before the delimiter is not a number.

5 is a non-numeric determination means immediately after, and a delimiter extraction means 3
The position of the delimiter is taken from , and it is determined whether the character immediately after the delimiter is a number.

A signal is output to the OR gate 6 when the character immediately after the delimiter is not a number.

Reference numeral 6 denotes an OR gate, which outputs a signal to the conversion unit reading means 7 when a signal is sent from at least one of the immediately preceding non-numeric determining means 4 and the immediately following non-numeric determining means 5.

7 is a conversion unit reading means, which receives the position of a delimiter from the delimiter extraction means 3 when a signal is sent from the OR gate 6, and stores the kana character string up to the position of the delimiter as a character string. It is read from the means 2 and output to the kana-kanji conversion means 8.

Reference numeral 8 denotes a kana/kanji conversion means, which converts the kana character string sent from the conversion unit reading means 7 into a character string containing kanji/kana and outputs the converted character string. This kana-kanji conversion means 8 can be realized using known technology.

Next, the operation of the Japanese language input device of this embodiment will be explained using an example.

It is assumed that the following kana character string is input by the character string input means 1 and stored in the character string storage means 2.

Ichiro Kunha, Otsuriki Inikimashita, 2゜500 Entsu Ka Sabukatsuchi, 1 Man Ensawodashimashita, Otsuri Haikuladesho, Konomon Dai no Seiriki Iritsuha,
95.5% Datta.

At this time, the delimiter extracting means 3 first extracts the comma (1) immediately after "Ichiro Kunha", and the 8th character at that position is passed to the immediately preceding non-numeric determining means 4, immediately following non-numeric determining means 5, and conversion. It is output to the unit reading means 7. Immediately before non-numeric character determining means 4 determines whether or not the position immediately before the 8th character (7th character) is a numeric character.

Since "c" is not a number, a signal is output to the OR gate 6. At the same time, the immediately following non-numeric character determining means 5 determines whether or not the 8th character (9th character) is a numeric character. "O"
Since is not a number, it outputs a signal to OR gate 6. As a result, the OR gate 6 outputs a signal to the conversion unit reading means 7. The conversion unit reading means 7 receives the signal from the OR gate 6 and converts the character string "Ichiro Kunha," up to the 8th character of the delimiter extracted from the delimiter extracting means 3 into the kana-kanji converter 8. Output to. The kana-kanji conversion means 8 converts this into a kanji-kana mixed character string ``Part-kun-kimi wa,
” and output.

Next, the delimiter extracting means 3 extracts the period (.

). The preceding non-numeric character determining means 4 outputs a signal to the OR gate 6 since the <18th character>"Yu" is not a numeric character. Immediately after, the non-numeric determining means 5 detects the <20th character> [
Since 2) is a number, no signal is output to the OR gate 6. Since the OR gate 6 receives the signal from the immediately preceding non-numeric determining means 4, it outputs the signal to the conversion unit reading means 7. The conversion unit reading means 7 receives the signal from the OR gate 6 and converts the character string "Otsuriki iniikimashita," from the 9th character to the 19th character into the kana-kanji conversion means 8.
Then, by the kana-kanji conversion means 8, a character string containing kanji and kana characters such as ``I went to run an errand.'' is obtained.

Next, the delimiter extraction means 3 extracts <21 immediately after “2”.
Extract the comma (1) in the character>. The immediately preceding non-numeric determining means 4 does not output a signal to the OR gate 6 because the <20th character> r2J is a numeric value. Immediately after, the non-numeric determining means 5 determines that the <22nd character>"5" is a number, so O
No signal is output to R gate 6. As a result, no signal is input to the OR gate 6 from either the immediately preceding non-numeric determining means 4 or the immediately following non-numeric determining means 5, and no signal is output to the conversion unit reading means 7. Therefore, the conversion unit reading means 7 and the kana-kanji conversion means 8 do not operate.

Similarly, <34th character> comma (1), <48th character> period (,), <60th character> period (
, ), the <75th character> comma (1), and the last period (.

), a signal is output from the OR gate 6, but <
For the period (,) of the 78th character, use OR gate 6.
As a result, no signal is output from the character string storage means 2.
The kana character strings stored in the .

Claims (1)

[Claims] When dividing a character string into multiple units, extract delimiters such as commas, commas, and periods from the character string, determine whether the characters before and after the delimiter are numbers, and select the characters immediately before the delimiter. Alternatively, when there is no number immediately after the delimiter, the character string is divided by the delimiter, and when there are numbers immediately before and after the delimiter, the character string is not divided by the delimiter.
