Abstract

PURPOSE:To give correction to a converted character string in a simple way by deleting the characters one by one at the position of a cursor and then deleting the word of the converted character string when the reading characters corresponding to a word of the converting string are all deleted. CONSTITUTION:A character string 'SYUGOJIKAN O KAERU' is displayed on a converted character string display area 44, and a cursor 48 and a character string 'KAERU' are displayed with inversion (Fig. A). When a character deletion key 58 of an input device is operated, the characters indicated by a cursor 40 are deleted among those reading characters shown in an input character string display area 46. In this case, a character is deleted for each operation of a character deletion key 56. The cursor 40 indicates a character 'E' after a character 'KA' is deleted since the cursor 40 has no change of its position. Thus the reading characters are deleted successively and no reading character is displayed any more in the area 46. Then only the cursor 40 remains (Fig. D). In this case, the corresponding converted character string 'KAERU' is also deleted from the area 44.

Description

[Detailed Description of the Invention] 1. The present invention relates to a string processing device, particularly a string processing device that derives a corresponding string from an input string, such as a Japanese word processor or a translation machine. This paper concerns a character correction method in solid kana-kanji conversion.

For example, the Kana-Kanji conversion method, which is widely used in Japanese word processors, generates a converted string from an input string in units of words or segments.
Since word processing such as confirmation and correction of Kanji words is performed on a word-by-word or segment-by-segment basis, there is a drawback that the frequency of operator intervention, that is, the frequency of keystrokes, is high.

On the other hand, in the so-called "solid writing conversion" method, the word breaks are extracted and converted to kanji for a string of reading characters input continuously in kana or romaji, and therefore the processing of the string is done in writing. Since it is a unit, it has the advantage of being simple to operate.

When inputting text using a keyboard, it may be necessary to correct the input character string due to an input error or a change of intention.

Such corrections or modifications are required to be easily performed by simple operations.

Traditionally, corrections or corrections were made by manipulating the "Backward" (/henkspace) key and other function keys on the keyboard. For example, when converting kana-kanji at the idiom level or phrase-cutting level, operate the back key to move the display cursor back, erase characters in order from the end of the input string, and then press the desired character key and ``Null''. The user operated the "Convert" key 16 to add a new character to the end of a sentence.

However, in the solid kana/kanji conversion method, such a correction method that requires many key operations is not desirable. In other words, although it is a solid kana kanji conversion method,
It is necessary to indicate the break between words or phrases by operating the ``conversion'' key or ``no conversion'' key. This not only requires the operator to make a decision each time he or she performs these complicated key operations, but also does not take full advantage of the features of the solid kana/kanji conversion system.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the drawbacks of the prior art and to provide a character correction method that allows a converted character string to be corrected with simple operations even in a solid writing conversion method.

1-1 In order to achieve the above-mentioned object, the present invention provides a character correction method for converting a first character string into a corresponding second character string by solid-letter kana-kanji conversion. The first of the second strings displayed
A first character string related to the word indicated by the cursor is displayed on the display device, and in response to the operation of the character deletion key,
This method is characterized in that the character indicated by the second cursor is deleted from the first character string displayed on the display device. Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

Referring to FIG. 1, an embodiment in which the present invention is applied to a Japanese word processor is shown in a conceptual functional block diagram. As shown in the figure, this embodiment uses an input device 20 such as a keyboard, a display device 22, and a kana-kanji conversion algorithm 24 that executes solid kana-kanji conversion by referring to a conversion dictionary 28 such as a kanji dictionary or a grammar dictionary. and has.

In this embodiment, the input device 20 is a kana or alphabetic input device.
It has a reading character key for inputting reading (phonetic) characters such as / ), and various cursor control keys. The cursor control key is used to control the display screen 38 (
A "cursor forward" key advances the cursor 40 displayed in the input character string display area 4G (Fig. 2) and the cursor 48 ('Fig. 3) displayed in the converted character string display area 44; It consists of a "cursor back" key that moves the cursor back.

Also, a converted character string display area 44 of the display device 22, which will be described later.
"insert" key, which is operated when inserting the desired character into
Converted character string display area 44 and input character string display area 46
It also has function keys such as a ``character delete'' key 56 (FIG. 3) that is operated to delete a desired character from among the characters displayed on the screen, and a ``convert'' key that instructs kana-kanji conversion. It also has a numeric keypad that is used when selecting multiple kanji candidates extracted during kana-kanji conversion.

The input device 20 further includes a mode designation key for designating the operating mode of the device. This will be discussed later. Of course, the input device 20 has other function keys, etc.
Since these are not directly related to the understanding of the present invention, their explanation will be omitted. Note that in this specification, the term "character" includes not only kana or alphabet letters, but also punctuation marks and other symbols.

Display device 22 may be, for example, a CRT character display device;
The reading character string input into this system and the character string resulting from Kana-Kanji conversion are visually displayed. The display screen 38 consists of areas, or lines, in which a plurality of characters are displayed in a plurality of horizontal rows, and in this embodiment, it consists of a total of 24 lines. The hatched part 3B is
As shown in FIG. 3, it consists of a converted character string display area 44 on the 22nd line and an input character string display area 4B on the 24th line. The remaining area 37 is a display work area where processing such as editing and arithmetic operations are performed on the data that has undergone kana-kanji conversion.

Character cursor 4 displayed in input character string display area 4B
In this embodiment, 0 is an underline "-" located below a single character, and the word cursor 48 displayed in the converted character string display area 44 normally indicates the character displayed in the converted character string. This is to display each word in black and white.

In the converted character month display area 44, the converted character string that is the conversion result is displayed. In addition, input character string display area 46
The conversion operation mode is displayed in the first half of the screen, and in the example shown in FIG. 3, an indication ``Kana/Kanji'' indicating that the mode is the Kana/Kanji conversion mode is displayed. Furthermore, an input character string and a cursor 40 are displayed inside the parentheses [] 47 in the latter half. Note that herein, the character string after conversion will be referred to as a converted character string.

In this embodiment, as shown in FIG. 3, the pronunciations are displayed in square brackets, and the breaks between words are shown as break marks, such as "/". That is, when reading a word in hiragana mode (kana-kanji conversion mode), delimiter marks "/" are displayed on the left and right sides of the reading.

The operating modes of this device are broadly divided into a direct input mode and a kana-kanji conversion mode. The direct input mode further includes an alphanumeric mode and a katakana mode, both of which allow direct input into the work area 37 by manual input. The kana-kanji conversion mode is a mode in which an input character string is converted into kana-kanji to create a converted character string and displayed in the display area 3B. In this mode, by operating the confirmation key of the input device 20, the converted character string in one display area 36 is transferred to the work area 37 and displayed there as a confirmed character string.

The Kana-Kanji conversion mode of this embodiment also includes Hiragana,
There are 10 modes: katakana, alphanumeric, proper noun, single kanji, symbol, ruby, period, fixed phrase, and 2-stroke. Furthermore, there are sub-modes such as Romaji input and full-width/half-width mode. Any of these modes can be selected using the mode designation key of the input device 20 described above.

The kana-kanji conversion algorithm 24 is a functional block that converts an input character string into a character string containing kanji, kana, and kanji using a commonly available kana-kanji conversion method. Broadly speaking, this has a word extraction function that extracts words from input reading character data, and a kanji conversion function that converts portions of the extracted words that correspond to kanji into kanji. When a predetermined amount of input character strings are accumulated in the temporary input data back 72B, the kana-kanji conversion algorithm 24 takes in data indicating the input reading character strings, indexes the conversion dictionary 28 such as a kanji dictionary and a grammar dictionary, and indexes the input character strings. Executes the Kana-Kanji conversion process. Since the specific processing in these functions is not directly related to the understanding of the present invention, a description thereof will be omitted.

The Kana-Kanji conversion 7' algorithm 24 and other blocks are advantageously implemented by a processing system such as a microprocessor, and are shown in blocks according to their functions in the figure. For example, the input device 20 is associated with a temporary input buffer 26 that temporarily stores input signals generated in response to operations of these keys.

The editing processing unit 34 provides input data to the kana-kanji conversion algorithm 24 and converts the kana-kanji conversion algorithm 24
The Kana-Kanji conversion process, such as selection of candidate words output from Process.

The display circuit 30 is a circuit that controls the display device 22,
The display data is stored in the display memory 32. The display memory 32 has two storage areas: a conversion row area and an input row (reading) area. The contents of the editing processing section 34 are transferred to the conversion line area under the control of the display circuit 30. This is displayed by the display circuit 30 on the conversion line 44, ie, the 22nd line, of the display screen of the display device 22 shown in FIG. Further, the contents of the temporary input buffer 2B are transferred to the input row area under the control of the display circuit 3Q. This is displayed by the display circuit 30 in the input display section 46 of the display screen, that is, in [ ] 47 on the 24th line.

In the hiragana mode of the kana-kanji conversion mode, input device 2
When a reading character string is input by 0, it is temporarily accumulated in the input temporary buffer 2B and displayed in the input character string display area 4.
It is displayed on B. This is converted into a kanji-kana mixed sentence of the converted character string by the editing processing unit 34 and the kana-kanji conversion algorithm 24, and is displayed in the converted character string display area 44.

For example, in the example shown in FIG. 3, the converted character string "Change meeting time" is displayed in the converted character string display area 44, and the character string "Change" is highlighted as the cursor 48 ((A)). Along with this, the pronunciation character string "kaeru" corresponding to the highlighted character string "kaeru" is displayed in the input character string display area 48, and the cursor 4o is normally positioned at the beginning of the pronunciation character string "kaeru". indicates the character ``ka''.

Then, when the input device 200 character deletion key 56 is operated, the input character string display area 46 appears as shown in (B) and (C).
The character indicated by the cursor 40 among the reading characters displayed on the screen is deleted. This is character deletion key 5
Each time you operate 6, one character is deleted. cursor 40
Since the position of does not move, when the character "ka" is deleted, the cursor 40 points to the next character "e".

When the reading characters are deleted one after another in this way, there are no reading characters displayed in the input character string display area 46, and only the cursor 40 remains ((D)). At this time, the corresponding converted character string "Change" is also deleted from the converted character string display area 144. That is, until then, the corresponding converted character string "Kaite" remains displayed in the converted character string display area 44, but only when all the pronunciations of one word in the converted character string are deleted does that word appear. will also be deleted.

Such control is performed by the editing processing section 34 and the display circuit 30.
An example of the II control flow is shown in FIG. First, when the character deletion key 5B of the input device 2o is operated, it is processed as an error if it is not in the correction mode (122), and if it is in the correction mode, the processing is different depending on whether the input mode is the kana-kanji conversion mode or not. (102).

First, if you are in Kana-Kanji conversion mode, move the reading cursor 4
It is determined whether 0 indicates a character or a non-character, that is, a delimiter (104), and if it indicates a character, the number of reading characters displayed in the input character display area 46 is determined. (toe), number of reading characters is 2
If there are more than characters.

The character indicated by the cursor 40 in the input character display area 4B is deleted (108), and the remaining character string is displayed (110).

If the number of reading characters displayed in the input character display area 46 is one character, first, the converted character display area 44
112), and if there is a word following it, the word cursor 48 is moved to the position of the latter word (+
14). Therefore, the input mode of the following word is determined,
If this is input in Kana-Kanji conversion mode,
The reading is displayed in the input character display area 4G. At the same time, the latter word is highlighted as a cursor 48 (+20).

Note that the embodiments described here are for explaining the present invention, and the present invention is not necessarily limited thereto, and modifications and variations that can be made by those skilled in the art without departing from the spirit of the present invention. Modifications are within the scope of this invention. For example, in the illustrated embodiment, the conversion line and the reading area are provided separately, but the conversion line may have a separate reading area and the reading characters may be stored and displayed in the conversion line.

肱-1 In this way, the character correction method according to the present invention can delete the reading character at the cursor position one character at a time, and when all the reading characters corresponding to one word in the conversion string are deleted, the conversion Words in the string are also removed. This makes it possible to modify the converted character string with a simple operation even in the solid writing conversion method.
