Abstract

PURPOSE:To obtain a character processor improved in conversion efficiency by retrieving ideographic characters of which reading is partially different from an inputted phonetic character string when ideographic characters having the same reading as the inputted phonetic character string are not retrieved from an ideographic character dictionary. CONSTITUTION:When the ideographic characters having the same reading as the inputted phonetic character string are not retrieved from the ideographic character dictionary, the ideographic characters of which reading is partially different from the inputted phonetic character string are retrieved. When a input is applied from a keyboard 5 for instance, character processing is executed in accordance with a control means stored in a read-only memory 12 or the like under the control of microprocessor 1. When the start of ''kana'' (Japanese syllabary)/''kanji'' (Chinese character) conversion is decided by a data string inputted from the keyboard 5, the ideographic characters having the same reading as the inputted phonetic character string are retrieved from the word dictionary. If there is no registered word coincident with the inputted character data string as the result of retrieval, characters of which reading is different from the inputted character data string only by one ''kana'' character are retrieved and the retrieved characters are stored in a data register DTABL and outputted.

Description

TECHNICAL FIELD The present invention relates to a character processing device that is improved so that it can efficiently convert phonetic characters into ideographic characters, such as kana-kanji conversion.

Prior Art In the kana-kanji conversion method of conventional character processing devices, the operator inputs pads to output "Minister".
When inputting , if the word ``Minister'' is registered as ``Daijin'' in the dictionary of the storage device ``2'', ``Minister J'' can be output as the conversion output. but,
Registered word dictionary-H has the word “minister” as “daijin”
If the kanji is registered with the reading ``Minister'', even though there is a single dΔ for ``Minister'' that the operator intended, only one character ``ji'' in the input Kana character is different, and that kanji [Minister J] cannot be converted. There wasn't.

Purpose In view of the above, an object of the present invention is to convert an input phonetic character data string into an ideogram, and when there is no ideogram with a reading corresponding to the input phonetic character data string, It is possible to convert the input phonetic character data string into an ideographic character whose reading is partially different, thereby obtaining a conversion output similar to that obtained by correcting a part of the operator's input phonetic character data string. It is an object of the present invention to provide a character processing device which can improve conversion efficiency significantly.

Example The present invention will be described in detail below with reference to the drawings.

FIG. 1(A) shows an example of the overall configuration of the character processing device of the present invention. In the illustrated configuration, 1 is a microprocessor sensor, and 2 is an address bus that specifies the address of each input/output memory. Further, 3 is a data bus, which is a bidirectional path used for transferring various data, and 4 is a control/bus, which is used for reading, writing, etc. of each memory, etc.
It is used to accept Interab I, transmit data set timing, etc. Furthermore, 5 is a keyboard, on which various keys such as alphabet keys and hiragana keys are arranged, and 6 is a keyboard controller.

The keyboard controller 6 encodes data inputted through the keyboard 5 and sends an interwoven signal to the control path 4. Next, 7
is a CRT controller, and a display (CRT) device 8,
Character generator 8, refresh memory 10.
The refresh memory controller 11 is controlled. Further, the display (CRT) device 8 can perform a display similar to that of a normal television receiver, and the character generator 8 can input the character code, line address, etc. of the character pattern 7 by inputting the character pattern. The pattern of that row is sequentially output, and the Ritzch memory 10 stores the character code to be displayed on the CRT device 8.
The refresh memory controller 11 repeatedly outputs the character code in response to display instructions from the GRT controller 7, and the refresh memory controller 11 performs two consecutive refresh cycles and a microprocessor for the CR7 display in response to instructions from the CRT controller 7. Controls writing and reading of data from 1. Further, reference numeral 12 denotes a read-only memory, ie, a so-called ROM, which stores the control procedures shown in FIGS. 5 and 7 as well as various processing procedures. Further, 13 is a controller for the ROM 12, and 14 is a random access memory, that is, a so-called RAM, which is used for storing various data. As shown in the figure, each register DO
It has D2SBUF, DTABL, DC5L, etc. Each of these registers will be described later. 15 is RAM 14
16 is a floppy disk, 17 is a floppy drive device, and 18 is a controller for the floppy drive device. Further, 18 is a printer, and 20 is a controller for the printer.

The character processing device of the present invention, which is composed of the above-mentioned components, is operated by input from the keyboard 5. When an input is made from the keyboard 5, an inclination signal is transmitted to the microprocessor l. Various control operations necessary for character processing are performed according to the control means stored in the RO old 2.

FIG. 1(B) shows a part of a group of keys arranged on the keyboard 5. As shown in FIG. In the figure, 22 to 2θ are cursor movement keys, 22 is a key that moves the cursor up one position on the display screen, 23 is a key that moves the cursor one position to the left, and 24 is a key that moves this cursor to the top left corner of the display screen. 25 is a key to move the cursor one place to the right, and 28 is a key to move the cursor one place down.

Further, 27 and 28 are monitor cursor movement keys, 27 is a key to move the monitor cursor on the monitor one position to the left, and 2 is a key to move the monitor cursor one position to the right. 28 is a key for displaying a homophone string for the input character data string after conversion into kana-kanji characters on the monitor 2, and 30 is a key for moving the homophone string on the monitor cursor to the cursor position on the display screen.

Next, FIG. 2 shows an example of the structure of a word dictionary registered on an IC memory or a memory disk. Therefore, each word to be registered is made up of 8 words, and each word is made up of, for example, 18 bits. In a word with this structure, the first 7 bytes contain reading information, the next l /< ite contains grammatical information, and the next 3 words following those first 4 words contain kanji. Enter the code, and enter the grammar information in the last word as shown. Therefore, in the structure of such a word dictionary, there is a restriction that only up to 7 characters can be input for reading information, and up to 3 characters can be input for kanji.

Next, FIGS. 3(A) and 3(B) each show a data registrar table DTABL.

The data register DODISBUF shown in FIG. 3A stores the readings of the homophone string and the JIS code string of the kanji obtained by converting the input character data string into kana-kanji. When displaying on the display device CRT, the contents of this data register DODISBUF are output as homophones to the monitor area of the display device CRT. Data register I] The same kana character data string as the input character data string is placed at the beginning of QDISBUF, and then the delimiter II
, 11 kanji JIS code string is entered as pa, and the last j
Two punctuation marks are inserted after the ψ JIS code.

Data register table DTABL shown in FIG. 3(B)
stores a reading data string and a kanji data string of words whose readings match the input character data string except for the I character, which is not the first character. For tm words, a total of 7 words are drawn, consisting of 4 words as 8 reading characters and 3 words as 3 kanji characters.

FIGS. 4(A) and (B) show data register 000
The contents of TSBUF and the display mode on the display device 8 at that time are shown.

In the situation shown in both figures, if you typed in '°°' to output "minister", or if the data was read in the word dictionary,
There is no registered word that is ``, and even the kana-kanji conversion did not result in a conversion that corresponds to the reading of °daijin°. In this case, data register column I]OI]l5
If the JIS code is stored as shown in Figure 4 (A), the word ``Minister'' registered in the dictionary with the reading ``Daijin'' is shown in Figure 4 (B). displayed on the monitor. In addition, in the figure, C
8 is a cursor, and MC3 is a monitor cursor.

Moreover, FIG. 4(C) shows the state of the display screen after the selection key is pressed as described later in the state shown in FIG. 4(B).

Next, the operation of the character processing apparatus of the present invention will be explained according to the flowchart 1 shown in FIGS. 5(A) and 5(B).

First, in FIG. 5A, an input data string is read from the keyboard 5 in step 55-1.

In step 55-2, it is determined whether or not it is the beginning of ephemeral kanji conversion. If the kana-kanji conversion has not started, the process moves to step 55-3 and performs various processes such as code input, English character input, kana character input, etc., which are performed in a normal word processor. If it is the start of Kana-Kanji conversion, step 55
-Move to 4. In step 55-4, a word whose first character matches the input character data string and which is registered first in the dictionary is found from the word dictionary. For example, if you enter "Daijin", "Da"
Find words starting with in the dictionary. In the following,
The explanation will be based on an example in which "Daijin" is input.

In step 55-5, it is determined whether all the readings of the single 5h obtained in step 55-4 match the input data string "Daijin". If they all match, the process moves to step S5-11 and normal kana-kanji conversion is performed.

If they do not match, the process moves to step 55-6.

In step 55-6, the obtained reading is! Determine if everything matches except for the characters. If the pronunciation of the word you are currently identifying is "daijin",
Since everything else matches the input character data string except that "ji" is changed to "ji", the process moves to step 55-7. In step 55-7, it is determined whether or not the table DTABL of the data register has overflowed. If it has overflowed, the process moves to step S5-'10, and if it has not overflowed, the process moves to step 55-9. In step 55-8, the currently obtained word reading and kanji JIS code are stored in the data register table DTABL, and the process moves to step S5-10.

Here, you will be registered as ``Daishin'' and ``Minister.''

On the other hand, in step S55-6, if the input character data string and the data of two or more readings are different, step S5-1
Move to 0.

In step S5-10, it is determined whether there are any words starting with the first character of the input character data string in the dictionary. If there are more words, the process moves to step 55-8 to check the next registered word. If such a search is repeated and there are no registered words with a matching first character, the process moves to step S5-11.

In step S5-11, normal kana-kanji conversion is performed.

Next, in step S5-12 in FIG. 5(B), it is determined whether or not the input character data string °'Daijin' has been converted into a corresponding kanji character. If the conversion to kanji cannot be performed, the process moves to step S5-13. In step S5-13, words that differ by one character from the input character data string are stored in the data register table DTA.
It is determined whether or not it is stored in the BL. If the word is not stored, the process moves to step S5-15, and if it is stored, the process moves to step S5-14.

In step S5-14, the contents of the data register table DTABL are stored in data register 00015BUF.
Store in.

Here, FIGS. 6A and 6B show how the table DTABL and register DODISBUF are stored at that time. As shown in the figure, the reading and kanji JIS code strings stored in the data register table DTABL are
Transfer it to the area where the S code is stored and store it together,
A code corresponding to °°・”′ is entered at the end of the reading and kanji. Then, the process moves to step 95-18.

Referring again to FIG. 5(B), in step S5-15, the input character data string and the JIS code string of homophone kanji obtained by kana-kanji conversion are stored in the data register 0001SBUF as shown in FIG. .

If no kanji string corresponding to the input character data string is obtained during kana-kanji conversion, only the input character data string is stored.

In step S5-18, the homophones obtained as described above are displayed on the display screen of the display device 8.

In step S5-17, other processes associated with the word processor are performed.

Next, FIG. 7 is a flowchart showing the process of selecting homophones after the kana-kanji conversion.

In step 58-1, it is determined whether or not the selection search key 28 has been pressed. If it has not been pressed, the process moves to step 58-2 and other normal word processor processing is performed. If key 29 is pressed, step 58-3
Move to. In step 58-3, the reading and homophone data in the data register DODISBUF shown in FIG. 4(A) are sent to the monitor display area on the display screen of the display device 8, as shown in FIG. 4(B). Display on monitor. In step 58-4, wait until the selection key 30 is pressed, and when the selection key 30 is pressed, step 5
Move to 8-5. In step 58-5, the data of the homophone string located at the position of the monitor cursor MfES is transferred to the data register DC9L. In step 58-6, it is determined whether there is a code for the delimiter °゛Φ゛' in register [)C9L. If this code is found, the process moves to step 58-7.

If there is no code, the process moves to step 58-8. In step 58-7, the kanji code data after the delimiter in the register DC3L is stored again in the register DC8L, thereby leaving only the kanji code data in the register DC9L. In step 58-8, the kanji code data string in register DC8L is transferred to the address indicated by cursor C5 on the display screen.

Through the above process, the selected homophone on the monitor is moved to the position of the cursor CS on the display screen (Figure 4 (C)
reference).

In the above embodiment, if there is no registered word that matches the input character data string, only words whose kana pronunciation differs by one character from the input character data string are stored in the data register [
Although it is possible to store and output in 1 TABL, this number may be 2 or 3 characters, and the number of characters can be set arbitrarily.

Effects As is clear from the above explanation, according to the present invention, it is possible to obtain as a conversion output a word that differs from the input character data string in only a part but is the same as the input character data string. It is possible to convert and output words that are registered in the dictionary due to input errors or partially different characters, and realizes a character processing device that greatly increases the efficiency of conversion from phonetic characters to ideographic characters, such as in the case of Kanji conversion. can do.
