Abstract

PURPOSE:To simply execute correction by canceling a selection definite state of a single KANJI (Chinese character), when a single KANJI selection cancellation is instructed, and redisplaying a candidate word displayed immediately before the selection is decided definitely. CONSTITUTION:When it is informed that a cancellation key 14 is depressed to an input/output control part 21 from a key input part 10 after a single KANJI conversion is decided definitely, the contents of a cursor position register which is drawn back are read out of a drawback buffer 29, and the contents of the cursor position register are restored. Subsequently, an indefinite conversion result code which is drawn back in advance is read out and a homonym group in a conversion result storage buffer 30 is searched, and a word in which a displaying flag is set is read out. Next, since is selecting flag is set in an indefinite conversion result code, this character code is sent to a display part 22 by adding an underline attribute. The display part 22 displays a character by adding an underline from a designated position by the cursor position register, and displays a cursor in a designated position by the cursor position register.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a document creation device having a single kanji conversion function for converting input reading into a single kanji. The present invention relates to a cancellation method for canceling a state in which one of the selected single kanji candidates has been selected and confirmed.

(Prior Art) In general, document creation devices using the Kana-Kanji conversion method are
The reading data string input from the key manual means is divided into phrases using a word dictionary that stores grammatical information about the words and an adjunct dictionary that stores conjunctions, etc. It performs kanji conversion and displays the converted character string numbers containing kanji on the screen. However, in Japan, there are kanji with the same reading but different characters (letter notation), that is, homophones (homophones), so the converted word may be different from the word intended by the user. Therefore, the document creation device uses the converted homophone (
(Kana character strings may also be treated as homonyms) are not treated as the final conversion result, but are treated as homonyms that can be switched to other homonyms at the user's request, that is, homonyms that are subject to selection operations. The homophone that is currently the target of selection operation (selected homophone) is displayed on the screen with specific display attributes so that the user can recognize it.

In such document creation devices, if the homophone that is the target of a selection operation is not the desired word, the user can perform a key operation to request switching to another homophone (homophone candidate). . However, for personal names, place names, technical terms, etc., there are often no candidates registered in word dictionaries, and even if you switch homophones for these types of terms, you cannot obtain the desired word. First, simply converting kana to kanji using a word dictionary is not sufficient.

Therefore, the above-mentioned document creation device is
As shown in Publication No. 82, a dictionary (single kanji dictionary) is prepared in which the reading of one kanji character and candidates for kanji with that reading (referred to as single kanji) are registered.
A single kanji conversion function is provided to convert the u position into kanji. In a document creation device having this single kanji conversion function, when single kanji conversion is instructed for an input reading, single kanji candidates for this reading are displayed on the screen. When one of the single kanji candidates displayed on the screen is selected by a user operation, the single kanji for the above reading is determined, and the character code (kanji code) corresponding to that kanji is included in the document string information. embedded in. This is called single kanji selection confirmation. When this selection is confirmed, the kanji code is embedded in the document character string, so if the selection is confirmed by mistake, the character must be deleted and the single kanji conversion operation must be repeated from the beginning.

(Problem to be solved by the invention, A) As mentioned above, in the past, once one of the candidates converted into a single kanji was selected and the kanji for the reading was confirmed (selection confirmed), this kanji was corrected. There was a problem in that complicated procedures were required to do so.

Therefore, it is an object of the present invention to provide a method for easily correcting even if an incorrect selection instruction is given in selecting a kanji obtained by single kanji conversion.

[Structure of the Invention] (Means for Solving the Problem) This invention provides a method for selecting one of the single kanji candidates obtained by converting the input reading into a single kanji, and selecting the designated single kanji. A cancellation instructing means for instructing cancellation of the selected and confirmed single kanji in a state that it is confirmed and displayed on the screen, and a discriminating means for discriminating whether or not an instruction is given by the cancel instructing means are provided, and the discriminating means makes a distinction. Depending on the result, the selection confirmation state of the single kanji is canceled, and the candidate word that was displayed immediately before the selection confirmation (having the same reading as the previously selected kanji) is redisplayed. .

(Operation) According to the above configuration, when a cancellation instruction by the cancellation instruction means is determined by the discrimination means, the selection confirmation state of a single kanji is canceled and the candidate word that was displayed immediately before the selection confirmation is redisplayed. Therefore, it is possible to select this candidate word again, and even if you select a single kanji incorrectly, you can correct it by re-entering the reading of the single kanji that has been selected as before. becomes possible.

(Embodiment) FIG. 1 shows a functional block configuration of main parts of a document creation device according to an embodiment of the present invention. In the figure, reference numeral 10 denotes a key input section, including various character keys (not shown) and single kanji keys 11 for instructing conversion into one kanji character (ie, single kanji conversion). Conversion/next candidate key 12 for instructing kana-kanji conversion of the input reading, switching to the next candidate of the homophone converted to kana-kanji (switching display), etc., selection of the single kanji candidate obtained by single kanji conversion, homophone It has various function keys such as a selection/execution key 13 for instructing the selection of word candidates, and a cancel key 14 for instructing cancellation of the confirmed selection of a single kanji.

Reference numeral 21 denotes an input/output control unit that receives key human power from the key human power unit 1O, instructions to each unit corresponding to the input, and execution results of each unit in response to the instructions, and 22 an input/output control unit 2.
This is a display unit (comprised of a liquid crystal display, etc.) used for screen display under the control of 1. 23 is a kana-kanji conversion control unit that controls processes such as kana-kanji conversion according to instructions from the input/output control unit 21; 24 is a kana-kanji conversion control unit that performs kana-kanji conversion processing under the control of the ephemeral kanji conversion control unit 23, and converts homophones for each clause A kana-kanji conversion processing section 25 for obtaining candidates is a single kanji conversion processing section that similarly performs a single kanji conversion process and obtains a single kanji candidate.

2B General dictionary 4 consisting of a word dictionary storing independent words and grammatical information and an attached word dictionary storing attached words used in the kana-kanji conversion process of the short kana-kanji conversion processing unit 24! (including a proper noun dictionary), 27 is a single kanji dictionary that stores the readings of single kanji used in the single kanji conversion processing of the single kanji conversion processing unit 25 and homophones corresponding to these readings.

28 is an input buffer in which readings (reading data string) inputted from the key human power section IO are accumulated; 29 is a homophone that is the target of selection operation when single kanji conversion is instructed by operation of the single kanji key 11; This is a save buffer for saving word candidates (candidate words). 30 is a conversion result storage buffer in which the homophone candidates converted by the ephemeral kanji conversion processing section 24 are stored; 31 is a single kanji conversion result storage buffer in which the single kanji candidates converted by the single kanji conversion processing section 25 are stored; .

Each of these buffers 28 to 31 is placed in a memory (not shown) composed of, for example, a RAM or the like. Note that a printer device used to output documents, etc., a floppy disk device used to save documents, etc. are omitted.

Next, the operation of one embodiment of the present invention will be explained with reference to FIGS. 2 to 5.

First, when the character keys of the key human power unit 10 are operated and a kana character string with reading is input (for example, "Kono Fukei wo Kaku"), the input/output control unit 21 inputs this kana character string in units of characters. Loaded into input buffer 28.

The input/output control section 21 displays the characters loaded in the input buffer 28 in order from the cursor position currently displayed on the screen. Note that this device is equipped with a cursor position register that stores the coordinates of the X digit and Y line on the screen, and also stores the coordinates of the display memory (which the display section 22 has) corresponding to the coordinates on the screen. Storage locations are managed. Then, the display section 22 writes the cursor pattern into the display memory according to the contents of the cursor position register and displays the cursor. Further, each control section shown in FIG. 1 is configured so that the current cursor position can be determined by looking at the contents of the cursor position register. Also, since the position of the first line on the screen is managed separately, adding the contents of the cursor position register and the X and Y coordinates of the first line 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, the input/output control unit 21 reads the contents of the cursor position register, sequentially increments digits from this position coordinate, and passes the display position coordinate and character code to the display unit 22. When the conversion/next candidate key 12 is operated in this state, the input/output control unit 21 passes the kana character string stored in the input buffer 728 to the kana-kanji conversion control unit 23, and activates the kana-kanji conversion.

The kana-kanji conversion control unit 23 starts the ephemeral-kanji conversion processing unit 24, searches a general dictionary from the input kana character string, extracts independent words and adjunct words, and takes into account grammatical connections, use of predicates, etc. The system extracts phrases using the syntax check, outputs homophones of independent words for which the grammar check was successful, and performs kana-kanji conversion. Since the method of kana-kanji conversion is well known to those skilled in the art, detailed explanation will be omitted.

The homophone j meaning words outputted as the result of the above-mentioned kana-kanji conversion are stacked in the conversion result storage buffer 8° in accordance with their readings.

FIG. 4 shows the output code when homonyms exist. If the conversion result is a uniquely determined character (hiragana, katakana, alphanumeric characters, symbols), 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 on the page). If a homophone exists as a result of the conversion of the reading, the conversion result of this reading is stored in the document buffer in the form of the code shown in Figure 4. be done.

Homonyms corresponding to readings are stored in the conversion result storage buffer 30
This code (hereinafter referred to as the 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 30 indicated by the pointer 41.

Here, the conversion result of the above-mentioned input kana character string ``Kono Fukei wo Kaku'' is shown in FIG. There are homophones for the readings ``ko'', ``fuukei'', and ``kaku'', and ``no''.
``Ha'' has been confirmed as a particle in hiragana. 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.

Further, a selection flag 43 is set in the undefined conversion result code of the last reading part where the homophone exists. This indicates that this reading is subject to homophone selection. The conversion result storage buffer 30 includes a character code storage section 52, a character count storage section 53, a flag (display flag) 54 indicating a word to be displayed as a candidate from a homophone group, and the next homophone for the same reading. A pointer storage section 55 (if the end code E is stored in the pointer storage section indicates that the word is the last of the homophones) is provided. As shown in Figure 5, there are four homonyms for "ko": "ko/ko/ko/ko", and there are also two and eight homonyms for "fuukei" and "gaku", respectively. It has been shown that there is a homophone power of j. 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 "ko", "landscape", and "writing".

When the conversion is completed, the process is returned to the input/output control unit 21, and a temporary conversion result is displayed. The human output control unit 21 reads codes one by one from the storage position of the document buffer (51) corresponding to the cursor position at the time when reading input is started. If the read code is a character code, the input/output control unit 21 passes the character code to the display unit 22, and the display unit 22 displays the character corresponding to the position specified in the cursor position register, and displays the character code in the cursor position register. Update the contents by one digit. If the code is an undefined conversion result code, pointer 4
accesses the conversion result storage buffer 30 from the contents of 1;
The code of the word for which the on-display flag 54 is set is read, and the character codes corresponding to the number of characters stored in the number-of-characters storage section 53 are passed to the display section 22 with overlined attributes attached. In this state, "Write this scenery" is displayed, and the cursor is "<
" is displayed next to ".

Here, if the conversion result of "write" is not what you want,
Move the cursor to the "Write" position.

When the input/output control unit 21 detects that a cursor key is pressed, it reads out the contents of the cursor position register, changes the line position in the instructed direction, converts the changed cursor position to the line position within the page, and stores it in the document buffer. (51) and read the code at the relevant position. It is now assumed that an undefined conversion result code of [1: O: C] is read from the position corresponding to "<". When the undefined conversion result code is read, the input/output control unit 21 searches up to the first code in the list of undefined conversion result codes while updating the contents of the cursor position register, and sets the selection flag 43 to "1#". Then, the input/output control unit 21 adds an underlined attribute to the character code pointed to by the pointer (C) of this undefined conversion result code and gives it to the display unit 22.Then, the "write" part is changed. Homophone selection/confirmation target,
The display will be as shown at the top of Figure 5 (the cursor will point to
location of the book (not shown).

When the conversion/next candidate key 12 is pressed in this state, the human output control unit 21 points out the unconfirmed conversion result code pointer (41).
The conversion result storage buffer 30 is accessed, the next homophone is newly searched from the pointer (pointer storage section) 55 of the word for which the currently displayed flag 54 is set, and the currently displayed flag 54 is turned on. At the same time, the string after this word is redisplayed. At this time, the number of characters increases or decreases, so the input/output control unit 21 deletes the undefined conversion result code (when the number of characters decreases) based on the number of characters of the homophone candidate read from the conversion result storage buffer 30. , insertion (when the number of characters increases), and also processes the padding and tracking of subsequent character strings. Confirmation of the desired word is performed by pressing the selection/execution key 13, but when the selection/execution key 13 is pressed while the desired word is displayed, the input/output control unit 21 changes the information in the document buffer (51). In place of the undefined conversion result code of the portion to be selected, the character code of the homophone pointed to by the pointer (41) of this code is entered.

Then, the display section 22 is instructed to display this portion again. At this time, since no attributes are specified, the characters are displayed normally.

Now, as shown in FIG.
If there is no desired homonym among the homonyms stacked on 0 (,
For example, if conversion from "kaku" to "stroke" is desired, Illll-11 is pressed to use the single kanji dictionary 27 to convert "kaku" into a single kanji whose reading is "kaku". The subsequent operation is shown in the flowchart of FIG. single kan key 1
When the input/output control unit 21 detects that 1 has been pressed, the document buffer (51
) in [1: 1: The code of C1 and the contents of the current cursor position register are saved to the save buffer 29,
Further, the corresponding homophone group in the conversion result storage buffer 30 is left without being cleared (step Sl).
. Next, the input/output control unit 21 searches for a homophone group based on the undefined conversion result code pointer (in this case, "C") in the document buffer (51), and searches for a string of hiragana characters (equivalent to the reading). The single kanji conversion processing unit 25 accesses the single kanji dictionary 27 to read homophones and allographs, and the single kanji conversion result storage buffer 31
(Step S2). Next, the input/output control section 21 numbers the kanji stored in the single kanji conversion result storage buffer 31 in units of a predetermined number (10 in this case) and passes them to the display section 22, which displays the kanji as shown in FIG. As shown in screen a, each kanji is numbered and displayed (if it cannot be displayed, convert/
When the next candidate key 12 is pressed, the homophones of the next unit are displayed) (step S3).

If the operator sees a desired kanji on the screen, he or she presses the key corresponding to that number. When a number key (for example, "5") is pressed, the input/output control unit 21 reads the corresponding kanji ("kanji") from the single kanji exchange result storage buffer 31 (step S).
4), the arrangement of the undefined conversion result codes in the document buffer (51) (here El: 1:・C]
The beginning of [1: 1: C1) is replaced with this Kanji code and other undefined conversion result codes are deleted. If a code exists after the deleted undefined conversion result code, fill in the characters.

Then, the code stored after the specified position with the cursor in the document buffer is sent to the display section 22, and the conversion result is displayed as "enlarged" as shown on the display screen of FIG. 3b. Finally, the contents of the cursor position register are updated by one digit, and the cursor changes as shown in the display screen in Figure 3.
is displayed in the next digit position after the character “Expansion” (step S5).
.

Here, when the input/output control unit 21 is notified from the key input unit 1O that the cancel key 14 has been pressed (step 513), the input/output control unit 21 reads the contents of the save buffer 29, and The state is restored (step S7).

That is, the contents of the cursor position register that were previously saved are read from the save buffer 29, and the contents of the cursor position register are restored. Next, the previously saved unconfirmed conversion result code [1: 1: C] is read out, the homophone group in the conversion result storage buffer 30 is searched, and the word for which the display flag 54 is set ( character code) (in this case, ``written <''). Since the selection flag (43) is set on the unconfirmed conversion result code, this character code is sent to the display section 22 with an underline attribute attached. The display section 22 displays an underlined character ("written <") from the position specified by the cursor position register, and also displays a cursor at the position specified by the cursor position register. If the display screen d in FIG. 3 is displayed and the screen stops, this operation enters the key-operation standby mode, but in the case of the display screen C, steps S1, S2. Repeat the operation of S3 to wait for key power during single kanji conversion. Note that if another key is pressed before the cancel key 14 is pressed, the input/output control section 21 clears the contents of the save buffer 29 and executes the specified process.

[Effects of the Invention] As detailed above, according to the present invention, when a single kanji selection cancellation is instructed, the single kanji selection confirmation state is canceled and the candidate word that was displayed immediately before the selection confirmation is redisplayed. Therefore, it becomes possible to perform a selection operation again targeting this candidate word. Therefore, even if a single kanji is selected incorrectly, it is now possible to correct the reading of the single kanji once the selection has been confirmed, without re-entering it after securing an input area for the number of readings. .
