Abstract

PURPOSE:To bring the KANA (Japanese syllabary) character-string which is corrected to KANA to KANJI (Chinese character) conversion again by executing a correction of reading by executing a space insertion into the front of an arbitrary character of a reading correction object KANA character-string, a deletion of an arbitrary character, and also, a substitution to other KANA character by one character unit. CONSTITUTION:A homonym which is outputted as a result of KANA to KANJI conversion is accumulated in a conversion result storage buffer 27. An editing work part 24 displays a temporary conversion result by using a screen display processing part 26. When a function key 13 and a space key 17 are operated in order to correct reading and its fact is detected by an input control part 21, the editing work part 24 retrieves a homonym group, reads out a word consisting of KANA characters, and delivers it to the screen display processing part 26. When a notice from the editing work part 24 is received, the input control part 21 delivers a KANA character-string to a KANA to KANJI converting part 22. The KANA to KANJI converting part 22 executes a KANA to KANJI conversion (reconversion) with respect to the KANA character-string containing a reading correction character which is delivered form the input control part 21.

Description

[Detailed Description of the Invention] [Purpose of the Invention (Field of Industrial Application) This invention relates to a document creation device using a kana-kanji conversion method that converts an input kana character string into a character string containing kanji, and in particular, The present invention relates to a kana-kanji conversion control system suitable for correcting and reconverting input characters after converting them into kana-kanji characters.

(Prior Art) Conventionally, in this type of document creation device, it is common to apply either Method 1 or Method 2 shown below as a correction method when an error in human characters is found after Kana-Kanji conversion. Met.

■ Method 1 involves performing key operations to return all converted character strings (character strings containing kanji) to the character strings before conversion (kana character strings), and then performing key operations to correct incorrect characters (or words). This involves performing key operations and finally converting everything again. With this method, after converting all the characters into the original kana string, the cursor must be moved character by character to indicate the character to be corrected. Therefore, if the kana string has a large number of characters, the number of key presses will be required. The disadvantage was that it increased. Furthermore, it is not easy to find incorrect characters in a kana character string.

■ Method 2 is applied to document creation devices that cannot convert character strings after kana-kanji conversion back to kana character strings before conversion. Next, key operations are required to open up a space in order to secure a manual character area for the kana character string necessary for correction (a kana character string that indicates the correct reading of the desired converted character string), or to delete unnecessary character strings. The user performs key operations to manually override the correct kana character string to the character string to be corrected, and finally converts the newly input kana character string. In this method,
The correction procedure is very complicated because it is not possible to correct only the incorrect characters, and a new reading string must be entered for the incorrectly converted character string (i.e., a homophone). Ta.

(Problem to be Solved by the Invention) As mentioned above, conventionally, when attempting to correct characters input by mistake after converting kana-kanji, the device cannot return the converted character string to the pre-converted kana character string. However, since it is not possible to correct only the incorrect characters, and it is necessary to correct the incorrectly converted character strings (i.e. homophones), the correction procedure becomes extremely complicated. . In addition, with devices that can only correct incorrect characters, reading corrections, insertions, and deletions cannot be performed until all character strings that have been converted to kana-kanji are returned to the original kana character strings. It was difficult to find the location, and moreover, it required many cursor movement operations to indicate the location.

Therefore, the problem to be solved by the present invention is to make it possible to easily replace, insert, and delete characters necessary for correcting erroneously input kana characters even after kana-kanji conversion.

[Structure of the invention] (Means for solving the problem) This invention instructs to correct the pronunciation of a homophone candidate that is a homophone selection target in a character string containing kanji that has been converted into kana-kanji. and means for converting a corresponding homophone candidate into a kana character string in response to an instruction from the reading correction instructing means, and displaying the same character string as a kana character string to be corrected with a specific display attribute. a means for instructing to vary the range of the kana character string subject to reading correction on a character-by-character basis; and a means for instructing to vary the range of the kana character string subject to reading correction to be displayed on the screen with a specific display attribute in response to instructions from this means. a kana character indicating means for indicating kana characters to be read corrected one by one; and a space for one character to be inserted before the kana character indicated by the kana character indicating means according to the instruction of the kana character indicating means. means for inserting a kana character, means for deleting a kana character designated by the kana character designation means in accordance with an instruction from the deletion designation means, and replacement for replacing the kana character designated by the kana character designation means with another kana character. The present invention is characterized in that the kana character string whose reading has been corrected by the deletion means or the replacement means is subjected to kana-kanji conversion again.

(Operation) According to the above configuration, when a correction instruction is given by the pronunciation correction instruction means, the homophone currently being selected is converted into a kana character string indicating its pronunciation. This converted kana character string is displayed on the screen with a specific display attribute to indicate that it is a kana character string subject to reading correction. The range of kana character strings subject to reading correction that is displayed on the screen with this specific display attribute is determined by the instruction from the reading correction range change instruction means.
Vary per character. Then, insert a space in front of any character in the kana character string to be corrected, delete any character, and replace each character with another kana character to read it. By correcting
This corrected kana character string can be subjected to kana-kanji conversion (re-conversion) again.

(Embodiment) FIG. 1 is a functional block configuration diagram showing an embodiment of a document creation device to which the present invention is applied. In the figure, lO is a keyboard. In addition to various character keys (not shown), the keyboard IO includes a left cursor key 11 for instructing cursor movement to the left, a right cursor key 12 for instructing cursor movement to the right, and Function keys 13 are provided for realizing various instruction functions in combination with invisible up and down cursor keys and other keys. In this embodiment, the function key 13 is used in combination with another predetermined key, such as a space key 17 to be described later, to instruct correction of the pronunciation of a homophone candidate that is a homophone selection target. The keyboard 10 further includes a conversion/next candidate key 14 for instructing conversion of input kana character strings into kana-kanji characters, switching to the next candidate for the homophone that has been converted to kana-kanji (switching display), Selection/Execution key 15 for instructing selection etc., Cancel key 1B for canceling various instruction states from the keyboard 10, Space key 17.1 for instructing insertion of a character space. A key 18 and a delete key 19 for instructing deletion of one character are provided.

21 is an input control unit that performs key manual processing and key discrimination processing from the keyboard IO, and gives instructions to various parts within the device according to the key discrimination results; 22 converts input kana character strings into character strings containing kanji; a kana-kanji conversion unit that performs processing to re-convert (re-convert) a kana character string corrected by reading correction after kana-kanji conversion;
3 is a dictionary consisting of a word dictionary in which independent words and grammatical information are stored, and an attached word dictionary in which dependent words are stored, which are used for kana-kanji conversion by the kana-kanji conversion unit 22; 24 is an input control unit 21;
This is an editing work unit that performs various editing processes in accordance with instructions from the editor. 25 is a display device such as a liquid crystal display for displaying documents, etc.; 2B is a screen display processing unit that displays documents on the display device 25; and 27 is a homophone (homonym) converted by the kana-kanji conversion unit 22. This is a conversion result storage buffer in which candidates for different synonyms are stored.

Next, the operation of one embodiment of the present invention will be explained with reference to FIGS. 2 to 6.

When creating a document, the user operates the character keys on the keyboard lo to input a kana character string (reading character string) indicating the pronunciation of a desired sentence using kana or Roman characters. Here, in order to create the sentence ``It's nice weather today.'', we will show the pronunciation, ``Today is good weather.''

”, but instead of inputting the character string ``Kiyo ha yoi mata nkitezu.

When a character key on the keyboard 10 is operated and a kana character string with a pronunciation of "Kiyo hayoi tenkitezu" is input, the input side part a 21 displays this kana character string character by character. The editing work unit 24
Notify. The editing section 24 uses the screen display processing section 2B to sequentially display the characters stacked in the input buffer by the input control section 21 on the screen of the display device 25, starting from the cursor position currently displayed. This device is equipped with a cursor position register (not shown) that stores the coordinates of the X digit and Y line on the screen, and a display memory (not shown) that stores the coordinates of the X digit and Y line on the screen. (which the processing unit 26 has) is managed. Then, the screen display processing section 26 writes the cursor pattern into the display memory according to the contents of the cursor position register and displays the cursor. Further, the editing work unit 24 shown in FIG. 1 and the like are configured so that the current cursor position can be determined by looking at the contents of the cursor position register. Also, since the line column position at the top of the screen is managed separately, adding the contents of the cursor position register and the X and Y coordinates of the top line Fti position on the screen will determine the line in the page where the cursor is currently located. It is now possible to grasp the position of the digits. Therefore, editing work section 2
4 reads the contents of the cursor position register, sequentially increases the product from this position coordinate, and passes the display position coordinate and character code to the screen display processing section 26. In this state, enter punctuation, use the conversion/next candidate key 14 or the selection/execution key 1.
5 is performed, or when the input buffer 28 becomes full, the input control section 21 passes the kana character string accumulated in the input buffer to the kana-kanji conversion section 22, and converts the kana-to-kanji character string. Start it up. Here, it is assumed that the kana-kanji conversion unit 22 is activated to perform kana-kanji conversion in response to the input of a period. The subsequent operation is shown in the flowchart of FIG.

The kana-kanji conversion unit 22 performs a kana-kanji conversion process on the kana character string passed from the input control unit 21 in response to a kana-kanji conversion instruction from the input control unit 21 (step SL). That is, the kana-kanji conversion unit 22 converts the input kana character string into the dictionary 23.
Search for independent words and adjunct words, extract clauses by taking into consideration grammatical connections, use of predicates, etc., output homophones of independent words for which the grammar check was successful, and convert them into kana-kanji. Perform the conversion.

Since the method of kana-kanji conversion is well known to those skilled in the art, detailed explanation will be omitted.

The homophones output as a result of the kana-kanji conversion in step S1 are stored in the conversion result storage buffer 27 in accordance with their readings. FIG. 4 shows the output code when homonyms exist. If the conversion result is a uniquely determined character (plain name, katakana, alphanumeric character, symbol), the character code indicating that character is the document buffer in which the document is stored (not shown/each code storage location in the document buffer is a page). ), but if there is a homophone as a result of the conversion of the reading, the conversion result of this reading will be the fourth one.
It is stored in the document buffer in the form of the code shown in the figure. The homophone corresponding to the reading is the conversion result ta /< ffa 2
This code (hereinafter referred to as undefined conversion result code) contains a pointer (homophone buffer pointer) indicating the beginning of the area where homophones are stored.
1 is set. Also, a flag 42 for distinguishing this code from a normal character code, and a flag 4 for indicating that this homophone is a target of selection processing.
3 is also provided. That is, the attribute that a homophone exists is indicated by a flag 42, and the corresponding homophone group is stored from the storage position of the conversion result storage buffer 27 indicated by the pointer 41.

Here, input the above input kana string ``Kiyo ha yo tenki tezu.

” is shown in FIG. 5. There are homophones for the pronunciations of ``kiyo'', ``yoi'', and ``tenki'', and ``ha''.
, ``desu'' has been confirmed as a particle or auxiliary verb in the plain name. Therefore, the character string stored in the document buffer is in the form indicated by reference numeral 51. Note that the same unconfirmed conversion result code is embedded for the number of characters of the currently displayed candidate. In addition, the unconfirmed conversion result code of the last reading where a homophone exists has a selection flag (
43) will be erected. This indicates that this reading is subject to homophone selection. The conversion result storage buffer 27 includes a character code storage section 52, a character count storage section 53, a flag (displaying flag) 54 indicating a word to be displayed as a candidate from a homophone group, and the next homophone for the same-yomi. Each storage section 55 is provided with a pointer to a word (if an end code E is stored in the pointer storage section, it indicates that the word is the last of the homophones). As shown in Figure 5, for “Kiyo”, “
There are 9 homonyms for ``contribution 7 kuyo/.../kiyo'', and there are 7 homonyms for ``yoi'' and ``tenki'' each.
It has been shown that there are three homonyms.

In this embodiment, words written in hiragana are also stored as one of the homonyms. A display flag 54 is set for each reading to be displayed as a candidate. As shown in FIG. 5, a display flag 54 is currently set for each of the candidates "contribution,""good," and "weather."

When the conversion is completed, the processing is passed to the editing section 24. The editing section 24 uses the screen display processing section 26 to display the tentative conversion result. That is, the editing section 24 reads codes one by one from the storage position of the document buffer corresponding to the cursor position at the time when reading input is started. If the read code is a character code, the editing work unit 24 passes the character code to the screen display processing unit 2B, and the screen display processing unit 2B displays the character corresponding to the position specified by the cursor position register, and the cursor Update the contents of the position register by one digit.

If the code is an undefined conversion result code, pointer (4
Access the conversion result storage buffer 27 from the contents of 1), read the code of the word whose display flag 54 is set,
The character codes corresponding to the number of characters stored in the character number storage section 53 are passed to the screen display processing section 26 with overlined attributes attached. In this state, "Contribution is good weather." is displayed as shown by reference numeral 31 in Figure 3, and the cursor (the rectangular pattern with diagonal lines in Figure 3) is displayed at the position next to the period point "." be done.

Here, if the conversion result "contribution" is not the desired one because the user mistakenly entered "kiyo" instead of "kyo", the user corrects the pronunciation as follows. First, the user moves the cursor to, for example, the final character position of a homophone that was incorrectly converted due to a reading input error, that is, a character string to be corrected (here, "contribution") (step S2). Perform operations for. The contents of this operation are notified to the editing section 24 via the input control section 21, and the editing section 24 reads out the contents of the cursor position register and changes the line column position in the instructed direction, as well as changing the cursor position. is converted into a line column position within the page, the document buffer (51) is accessed, and the code at the position is read. Now, from the position corresponding to “y” [1: 0:
It is assumed that the undefined conversion result code of Al has been read. When the undefined conversion result code is read, the input control unit 2
1 searches up to the first code in the list of unconfirmed conversion result codes, and changes the selected flag 43 to "1#."Then, the editing section 24 sets the pointer (A) of this unconfirmed conversion result code. The character code pointed to is given an underlined attribute to the screen display processing unit 26.

Now, the "contribution" part becomes the homophone selection/confirmation target, and the display becomes as shown in the screen 32 of FIG. 3 and the upper part of FIG. 5. At this time, the cursor is at the "give" position (not shown in FIG. 5).

When the function key 13 and the space key 17 are operated for reading correction in the display state of the screen 32 in FIG. 3, and this is detected by the input control unit 21 (step Sl,
S4), the editing section 24 moves from the pointer (in this case, "A") of the undefined conversion result code in the document buffer (51) specified by the current cursor position to the (pronounced " Search for a group of homophones (for "kiyo") and read out a word (character code string corresponding to the reading/here "kiyo") consisting of hiragana characters. And editing work department 2
4 newly loads the read word (plain name character string) into the input buffer, and also displays this word in black and white inversion to indicate that it is the word (plain name character string) that is subject to reading correction. It is given an attribute and passed to the screen display processing unit 2B, and is displayed as shown in the screen 83 of FIG. 3 instead of the previous word ("contribution") (step S5). At the same time, the character string following this word is also redisplayed. At this time, if there is an increase or decrease in the number of characters, the editing work unit 24 changes the number of characters to the conversion result storage buffer 2.
Based on the number of characters of the homophone candidate read from 7, the unconfirmed conversion result code (here, (1:1:Al)) is deleted (when the number of characters becomes small) or inserted (the number of characters is increases),
It also performs padding and padding ρ processing for subsequent character strings. Note that the flat plate name character string (“
There is no change in the state of the homophone group in the same buffer 27 corresponding to "Kiyo"). If another key operation is performed in place of the operation of the function key 13 and space key 17, conventional processing indicated by the contents of the key operation is performed (step S6).

After requesting reading correction by operating the function key 13 and space key 17, if the user wishes to cancel this request, the user operates the cancellation key 16 to cancel the reading correction range (range of kana character strings subject to reading correction). If a change is necessary, operate the left cursor key 11 or right cursor key 12, and if the currently highlighted kana character string is read as is and is to be corrected, select/execute key 15 is operated.

If the cancel key 16 is operated and the input control unit 21 detects this (steps S7 and S8), the editing unit 24 changes the state of the display screen from the state of the screen 33 to the state of the screen 32 in FIG. That is, step S8. returns to the state before the function key 13 and space key 17 were operated. S
9), the control is returned to the input control unit 21 (the process of step S3). That is, when the cancel key 1G is operated, the editing work unit 24 selects the unconfirmed conversion result code [1: 1:
A] based on the pointer A of the conversion result storage buffer 27
Search for homophones within the group and read out the word (character code) for which the display flag 54 is set (in this case, "contribution")
). Since the selection flag (43) is set on the unconfirmed conversion result code, this character code with an underline attribute is sent to the screen display processing section 26 to be displayed on the screen. At this time, if there is an increase or decrease in the number of characters, an undefined conversion result code (here [
1: 1: A) ] ) is deleted or inserted, and subsequent character string filling and tracking processing is performed.

Further, when the left cursor key 11 is operated (step 512), the editing work unit 24 shortens the highlighted kana character string to be corrected by one character to the left (step 513).
) Delete the last character of the kana string in the input buffer. Similarly, when the right cursor key 12 is operated (step 514), the editing section 24 extends the highlighted kana character string to be corrected by one character in the right direction (step S15), and in the document buffer (51 ) (that is, the character code of the final character of the new highlighted character string) is loaded into the input buffer.

Furthermore, when the selection/execution key 15 is operated (step 510), the editing section 24 reads out the hiragana-kana character string in the manual buffer (which matches the highlighted flat name character string). And the editing work section 24.

The read plate name character string is given an underlined attribute and passed to the screen display processing unit 26 to be displayed on the screen (cancels the reverse display), and the contents of the cursor position register are changed to the last character position of the character string. It is updated so that it is pointed to (step 511).

Now, in this embodiment, the kana character string "Kiyo" which is highlighted on the screen 33 of FIG. 3 and the next character "Kiyo"
In order to read ``Kiyoha'' consisting of ``ha'' and make it a kana character string to be corrected, this state 1. ! The right cursor key 12 is operated once. As a result, "ha" is loaded in the input buffer following the character string "Kiyo" (pronunciation) for "contribution", and while only "Kiyo" was displayed in reverse video in the state of screen 33 in FIG. 3, As shown in the screen 34 of FIG.
"Kiyoha" will be highlighted. Select here/execute key 15
When is operated, the kana character string to be corrected is determined (to "Kiyoha"), and the state of the display screen changes from screen 34 to screen 35 in FIG. 3.

After the user operates the selection/execution key 15 to confirm the kana character string to be corrected, if he wishes to cancel this state, he operates the cancel key 1B and selects the position of the character to be corrected whose reading is indicated by the cursor. If a change is necessary, operate the left cursor key 11 or right cursor key 12, and if a space needs to be inserted for reading correction (addition of reading), press the insert key 1.
8, and if you need to delete unnecessary characters, press the delete key 1.
9, and if the reading needs to be corrected, manually input a kana character indicating the correct reading at the character position indicated by the cursor. When the reading correction is completed, the user operates the selection/execution key 15 or the conversion/next candidate key 14.

If the cancel key 1G is operated and the input control unit 21 detects this (steps 316 and 817), the editing unit 24 changes the state of the display screen (function key 13 and space key) in the same way as step S9. Step S to return to the state of the screen 32 (immediately before the key 17 was operated)
1g), the control is returned to the input control unit 21 (the process of step S3). In addition, the editing work unit 24 uses the left cursor key 11
is operated (step 520), the cursor position is moved back by one character (toward the left) (step 521), and when the right cursor key 12 is operated (step 522), the cursor position is moved back by one character (step 521). rightward) (step 52).
3), the control is returned to the input control unit 21 (the process of step S16).

Further, when the insert key 18 is operated (step 5
24) The input control unit 21 advances the character string by one character after the storage position in the input buffer corresponding to the current cursor position, and writes a space code at the same storage position. At this time, the editing work unit 24 uses the screen display processing unit 26 to advance the character string after the current cursor display position by one character and redisplay it based on the instruction from the input control unit 21, and also inserts a space character at the same position. is displayed with an underline (step 525).

At this time, the cursor position is advanced by one character.

Furthermore, when the delete key 19 is operated (step 5
2B), the input control unit 21 deletes the character at the storage position in the input buffer corresponding to the current cursor position, and pads the subsequent character string by one character. At this time, editing work section 2
4 uses the screen display processing section 26 to erase the character at the current cursor display position, and redisplays the subsequent displayed character string by padding it by one character in response to an instruction from the input control section 2I (step 527). - On the other hand, if kana characters are entered,
The input character is replaced with the character in the memory position in the human buffer corresponding to the current cursor position, and the input character is passed from the human control unit 21 to the editing work unit 24, and the character on which the cursor is displayed is replaced with the character stored in the human buffer. The text is displayed again (step 828). At this time, the cursor is advanced by one.

In this embodiment, it is necessary to add one character of the flat name before the underlined "ha" of "Kiyoha" shown on the screen 35 of FIG. is operated once. As a result, one character's worth of space is inserted before "ha" as shown in screen 3B of FIG. 3. Next, press the left cursor key 11 to correct the underlined ``yo'' in ``kiyo wa'' in screen 3B of Figure 3 to ``yo''.
When is operated twice, “
The cursor is moved to the ``Yo'' position. Next, on the screen 37 of FIG. 3, "yo" is overwritten from the position of "yo" indicated by the cursor, and the reading is corrected as shown on the screen 38 of FIG. At this time, the human buffer has
This means that ``Kiyoha'' is piled up. Note that the states of the document buffer (51) and the conversion result storage buffer 27 remain unchanged.

When the user finishes correcting the pronunciation, the user presses the select/execute key 1.
5 or the conversion/next candidate key 14.

The input control unit 21 manually selects the key in step 51G.
When it is detected that the execution key 15 or the conversion/next candidate key 14 has been operated (step 519), the editing section 24 is notified of this fact. The editing section 24 edits the document buffer (5
1) Detects the beginning position of the subsequent character string that was not subject to reading correction, and the character string from this position onwards to the character string immediately before the first occurrence of a punctuation mark or confirmed homophone. (plate name character string) and stores it in the input buffer. However, even if the input buffer is full, if no punctuation mark or confirmed homophone is found, or if the last character is loaded into the input buffer, the above operation ends. In addition, in order to obtain the above-mentioned flat name character string, if the code in the document buffer (51) is an undefined conversion code, it is sufficient to search the conversion result storage buffer 27 using the pointer (41). Needless to say. Here, ``Good Tenkitez'' is required.

When the editing unit 24 obtains the above-mentioned flat name character string, it loads this character string in the position subsequent to the flat name character string (“Kyoha”) already stacked in the input buffer, and sends a message to that effect to the input control unit 21. Notify. The input control section 21 is an editing section 2.
When the notification from 4 is received, the plain name character string (``Kiyoha Tenkitezu'') stored in the input buffer is passed to the kana-kanji conversion unit 22, and the kana-kanji conversion is activated.

The kana-kanji conversion unit 22 converts (reconverts) the kana character string including the reading correction characters passed from the input control unit 21 into kana-kanji characters in the same manner as in step S1 (step 529). As a result, as shown in FIG. 5
Furthermore, a group of homonyms for ``good'' and ``tenki'' are stored. Also, the contents of the cursor position register are
In the document buffer (51), the row column position is changed to correspond to the storage position of the first code of the unconfirmed conversion result code string with the same content for which the selection flag (43) is set, and from this storage position, the line shown in FIG. As shown, the undefined conversion result code corresponding to the homophone of "kiyo" is El: 1: A.
] instead of the undefined conversion result code [
1: 1: D] is written for the number of characters to be displayed (here, two characters). The writing of character codes or undefined conversion result codes to subsequent storage locations is also performed as shown in FIG. Then, according to the contents of the document buffer (51) and the conversion result storage buffer 27, a screen 39 shown in FIG. 3, that is, a kana-kanji conversion result for the correct reading is displayed.

In the above embodiment, the reading correction instruction is given by a combination of the function key 13 and the space key 17, but it is also possible to provide a dedicated reading correction instruction key.

[Effects of the Invention] As detailed above, according to the present invention, if an incorrect kana-kanji conversion result is obtained due to input of an incorrect pronunciation, the incorrect word (homonym) after conversion is selected. By doing this, it is possible to convert only this word into a kana character string that indicates its reading, and based on this converted kana character string, insertions, deletions, and even reading corrections can be performed, so only incorrect characters can be corrected. can be corrected very easily.
