Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a character processing device that performs kana-kanji conversion processing, and more specifically, a procedure for re-converting an input character string when it is not converted into a correct word. This invention relates to a character processing device that can easily perform the following operations.

<a> Conventional technology Conventionally, in this type of character processing device, a character string as conversion information inputted from a keyboard is temporarily stored in a power buffer, and when a conversion instruction is given from the keyboard, it is stored from the input buffer. The system is configured such that character strings are extracted in units of clauses, and kana-kanji conversion processing is performed sequentially from the beginning of the extracted clauses. If the phrase is not correctly extracted during continuous clause conversion and the conversion instruction is issued again, the length of the phrase will be replaced with a shorter phrase, or the phrase will be converted based on the phrase extraction position specified by the operator with the cursor. I was redoing it.

(c) Problems to be solved by the invention However, in the continuous clause conversion in the above character processing device, although it is possible to change the length of the clause, it is not possible to change the position of the initially extracted clause. Therefore, even if the conversion is performed again, the desired text cannot be obtained in most cases.

Further, (1) to (9) in FIG. 11 show a processing procedure for obtaining a desired sentence by the operator changing the position of phrase extraction. In (3) of the same figure, you find that the cutting position is incorrect and press the Cancel key to return to the state of (4) in the same figure. However, in order to move the cursor to the conversion position, press the cursor movement key. key or day key)
It was necessary to use the keys to move one space at a time, making key operations time-consuming. Further, this key operation is necessary from (6) in the same figure, and the longer the conversion target after the cursor position, the more times the cursor movement key is pressed. Therefore, such key operations have placed a significant burden on the operator.

The present invention has been made in consideration of the above circumstances, and provides a character processing device that can easily perform reconversion procedures when erroneous conversion occurs.

(d) Means for Solving the Problems The character processing device of the first invention includes an input means 1 for inputting character information and various instructions, and a character processing apparatus for storing the character information inputted from the input means 1 as a character string. column storage means 2;
Dictionary means 3 storing a large number of words corresponding to character information
, a display means 4 for displaying various information, a phrase cutting means 5 for receiving the first conversion instruction and cutting out a character string from the character string storage means 2 for each sentence yt5, and sequentially converting the cut out phrases into corresponding words. a conversion means 6 which outputs the converted word to the display means 4; and a conversion cancellation means 7 which reads the character string again from the character string storage means 2 and replaces it with the converted word currently displayed on the display means 4 when receiving a conversion cancellation instruction. and a phrase position indicating means 8 for instructing the phrase break when converted by the first conversion instruction, and a phrase for moving the specified phrase break in response to an instruction from the input means 1, in the replaced character string. and a delimiter moving means 9, when the second conversion instruction is given,
The present invention is characterized in that a clause is cut out based on the moved clause break and converted into a corresponding word.

Further, the character processing device of the second invention stores the phrase delimiter at the time of conversion in the phrase delimiter storage means 10, and causes the cursor movement means 11 to move the cursor at the time of canceling the conversion in units of the stored phrase delimiters. It is constructed so that it can be moved.

Further, the character processing device of the third invention stores the bunsetsu cutout position at the time of conversion in the bunsetsu delimiter storage means 10, and uses the cursor control means 12 to control the input means 1 when the conversion is undetermined.
The cursor is moved to the beginning or the end of the sentence in units of clauses in the direction of the beginning of the sentence, and when canceling the conversion, the cursor is moved in units of clauses in the direction of the beginning of the sentence, and the cursor is moved in units of clauses in the direction of the end of the sentence. The cursor is skipped and moved to the end of the undo range.

(E) Effect When the first character processing device issues a conversion cancellation instruction from the input means when an erroneous conversion occurs, the erroneously converted sentence being displayed is replaced with the character string before conversion, and the character string Inside, the bunsetsu separation when converting is indicated. Next, when the bunsetsu break is moved by an instruction from the input means and a conversion instruction is given again, bunsetsu segmentation is performed based on the moved bunsetsu break and conversion is performed.

Furthermore, in the second character processing device, when a predetermined cursor movement key is pressed when canceling conversion, the cursor moves toward the end of the sentence in units of clauses.

Furthermore, in the third character processing device, when a predetermined cursor movement key is pressed when the conversion is unconfirmed, the cursor moves toward the beginning or end of the sentence in units of clauses, and when a predetermined cursor movement key is pressed when canceling the conversion, the cursor moves. It moves in the direction of the beginning of the sentence in units of phrases, and in the direction of the end of the sentence, it moves to the end of the cancellation range.

(F) EXAMPLES The present invention will be described in detail below based on examples shown in the figures. Note that this invention is not limited by this.

4 to 6 illustrate an embodiment of the character processing device of the first invention, and FIGS. 7 to 9 illustrate an embodiment of the character processing device of the second invention. , 7 and 10, an embodiment according to the third invention will be described.

FIG. 4 is a block diagram showing the configuration of an embodiment of the first invention, and 40 is a keyboard as an input means for inputting a character string as conversion information for kana-kanji conversion. Note that the input means is not limited to the keyboard, but may also be constructed from a tablet device, OCR, or magnetic tape.

41 is a storage device as a storage means, and a keyboard 4
It stores the character string input from 0. The storage means includes, for example, a core memory, an IC memory, a magnetic disk, and the like.

Reference numeral 42 denotes a CRT as a display means, which outputs the results stored and saved in the storage device 41. Note that the display means is not limited to a CRT, and may be configured by, for example, a printer, a magnetic tape, a magnetic disk device, or the like.

43 is a sentence cutting processing device as a phrase cutting means;
When the character string stored in the storage device 41 is cut out in units of sentences and then in units of phrases, phrase breaks are stored as extraction positions. Sentence cutting processing device 43
For example, it can be configured from core memory, IC memory, ROM, magnetic disk, etc.

44 performs the following processing according to a program written in device M, which is composed of, for example, a 16-bit microprocessor. That is, when a conversion instruction is received from the keyboard 40, the sentence cutting processing device 43 is instructed to cut out a character string for each phrase from the storage device 4I, and the cut out phrases are sequentially converted into corresponding words and sent to the CRT 42. When a conversion cancellation instruction is received from the keyboard 40, the character string is read out again from the storage device 4I and replaced with the converted word currently displayed on the CRT 42, and the previously converted word is included in the replaced character string. A vertical ruled line is used to indicate a break between phrases, and when a conversion instruction is received from a keyboard 40, the position of the vertical ruled line is moved. Note that the control device 44 is equipped with a kana-kanji conversion dictionary.

Next, the operation of the above embodiment will be explained according to the flowchart shown in FIG. It is assumed that a character string is input from the keyboard 40 and stored in the storage device 4l, and that the character string is displayed on the screen of the CRT 42.

First, when the conversion key is pressed (step 50), the text extraction processing device 43 extracts the character string stored in the storage device 41 for each clause (step 51), and converts it into words by referring to the kana-kanji dictionary. (Step 52
). When the operator looks at the conversion result and finds that the cropping position is wrong (when the correct conversion is not done), the function +
When the conversion key is pressed (step 53), the converted text being displayed is restored to the character string before conversion (step 5).
4) At the same time, delimiters are indicated in the character string using vertical ruled lines (step 55). Here, the cursor is moved by operating the cursor movement key (step 5B-57).
, if you press the execution key at the position indicated by the vertical ruled line, the vertical ruled line will be erased and there will be no separation between clauses in that part.

Also, if you press the execution key at a position where there is no vertical ruled line, a new phrase break will occur at that position. When the setting of the bunsetsu break is completed, the bunsetsu break stored in the bunsetsu extraction processing device 43 is changed to the newly set bunsetsu break (step 58), and when the conversion key is pressed again (
Step 59), return to step 51, perform conversion again based on the changed phrase delimiter (step 52), and register the newly set phrase delimiter by the permanent function (step 60). When converting similar sentences, the desired sentence can be obtained by operating the conversion key - times.

Note that if there are no conversion candidates in the forcibly separated clauses, all processing is performed without conversion.

FIGS. 6(a) and 6(b) are diagrams showing an operation example of the above embodiment, and in both figures, the symbol A is a vertical ruled line indicating the phrase break of the revised phrase, and the symbol B is the phrase break after the change. This is a vertical ruled line that indicates.

As can be seen from the operation example shown in FIG. 6(b), because the segmentation of phrases was incorrect at a certain point, subsequent conversions were not performed correctly. Therefore, according to this example:
Even if the conversion is not performed correctly and the conversion is to be performed again, the conversion can be performed by simply changing the phrase break at a certain location instead of reconverting each phrase, and the desired sentence can be quickly obtained.

FIG. 7 is a block diagram showing the configuration of an embodiment of the second invention. Note that the same components as those in the first invention are designated by the same reference numerals, and the description thereof will be omitted.

70 is a device 70a composed of, for example, a 16-bit microprocessor, a kana-kanji conversion processing 170b, and an input editing processing section 7.
Qc, a storage controller 70d, and a display controller 70e. The key determination unit 70a determines which key among the function key, cursor movement key, cancel key, and other keys (conversion key, execution key, kana key, etc.) has been pressed.

The kana-kanji conversion processing unit 70b converts the character string input from the keyboard 40 and stored in the kana character string storage unit 41a into a sentence containing kana-kanji characters, and converts the character string input from the keyboard 40 into a sentence containing kana and kanji, and stores the character string in the converted character string storage unit 4 [c
to be memorized. The input editing processing unit 70c is in an undetermined state,
Determine the cancellation state, the state of the pond, and process the range of the undefined state, the range of the cancellation state, and the cursor position,
Edit information storage section 41dl. of storage device 41. : Stored as congestion information. The storage control unit 70d controls information input to or output from the storage device 41, and controls the display control unit 70.
e converts the information output from the input editing processing section 70c into a display signal.

The control device 70 in an embodiment of the second invention performs the following processing according to a program written in a ROM (not shown). That is, upon receiving a conversion instruction, a character string is cut out for each clause from the kana character string storage section 41a of the storage device 4l, and the segmentation of the segmented clauses is stored in the delimiter information storage section 4l.
b, and sequentially converts the cut out phrases into corresponding words and stores them in the converted character string storage section 41c, and outputs them to the display control section 70e. When the conversion cancellation right is received, the kana character string storage section The kana character string is read out again from 41a and replaced with the erroneously converted word displayed on the display means 42, and when the conversion cancellation instruction is given, the cursor is moved to the clause break stored in the break information storage unit 4lb. Move the cursor as a unit.

Next, the operation of the above embodiment will be explained according to the flowchart shown in FIG. 8 and the operation example shown in FIG. 9. In addition, as an example of a sentence to be converted into kana-kanji, ``estimate the expected amount゜゜ will be explained.

First, the character string "Mikomigaku wo sukuishuru" is input from the keyboard 40 (step 80).The input character string is determined to be a character by the key determination unit 70a (step 81), and the input editing processing unit 70c, it is stored in the kana character string storage section 41a of the storage device 41 by the storage control section 70d (step 82), and is displayed on the display means 42 via the display control section 70e (step 83).

FIG. 9(1) shows the display state.

When a conversion key is pressed from the keyboard 40 in this state, the key determination unit 70a determines that it is a conversion key (step 84), and the kana-kanji conversion processing unit 70b converts the character string stored in the kana character string storage unit 41a. , converted into a sentence containing kana and kanji, and the result is stored in the converted character string storage section 41 of the storage device 41.
c, and the phrase delimiter is stored in the delimiter information storage section 41b (step 86). Next, based on this result, the input editing processing unit 70c performs input editing, and the sentence containing kana and kanji is displayed on the display means 42 via the display control unit 70e (step 83). The display condition is shown in FIG. 9 (2). In the figure, the symbol “D” indicates the cursor position. Also, the character with an underline E placed before the cursor D “estimate” is one of the clauses automatically cut out from the character string. One of the following is shown. At this stage, the correct conversion has not been performed, so correction is necessary.

Next, as a correction work, when the execution key of the keyboard 40 is pressed to move the cursor D in units of clauses (step 87), the input editing processing unit 70c moves the cursor D in units of clauses via the key determination unit 70a. , move toward the beginning of the character string to be canceled (step 8g-8).
9) Display the cursor position on the display means 42 (step 83).

If there is no character string to be converted to be canceled, move cursor D to the phrase position in the next character string (step 90). FIG. 9(3) shows a state in which the execution key is pressed twice.

In this state, if you press the Cancel key to cancel the character string “Prospects are difficult” located in front of cursor D and reconvert (
Step 91), the input editing processing unit 70c moves the cursor D
When the previously located sentence containing kana and kanji is returned to the character string in the conversion library (step 92), the cursor D is moved according to the number of times the cancel key is pressed, and the cursor position is displayed on the display means 4.
2 (step 83). FIG. 9(4) shows a state in which the cancel key is pressed twice.

Next, the operator performs an operation to move the cursor D to a break between phrases that he or she believes will result in correct conversion. When the cursor movement key (day key) is pressed, the cursor position is as shown in Figure 9 (5) (steps 93-94), and when the conversion key is pressed here, the character string "Mikomi" is converted to "Mikomi". . The flow of the conversion process is as described above (step 84).
→85-86→83). FIG. 9(6) shows the converted state.

Next, the cursor movement process, which is a feature of this implementation ρj, will be explained. In conventional cursor movement, by pressing the cursor movement key (day key) three times, the cursor D
was moved to the position of the character ``pusu''.

In this embodiment, when the execution key is pressed, the phrase delimiter is stored in the delimiter information storage section 41b, so the cursor D can be moved. FIG. 9 (7) shows a state in which the execution key is pressed twice. From the example sentences in the example, it seems that there is not much difference between the conventional cursor movement operation and the cursor movement operation in this example.
However, the longer the conversion target that remains behind, the more effective the cursor movement processing of this embodiment becomes.

If you press the conversion key here, the character string ``Gaku wo'' will be converted to ``Amount wo''. FIG. 9(8) shows the converted state. Note that FIG. 9(9) shows the final converted result, and shows the state in which the execution key is further pressed to move the cursor D to the next character input position.

Note that if the cursor movement key is not pressed in step 93, the process moves to other processing (step 95).
.

(Hereinafter, blank space) Further, the control device 70 in an embodiment of the third invention is as follows:
ROM1. :Performs the following processing according to the written program. That is, upon receiving a conversion instruction from the keyboard 40, a character string is cut out from the kana character string storage unit 41a for each clause, the segmentation of the segment at the time of segmentation is stored in the delimiter information storage unit 41b, and the segmented clauses are sequentially handled. When an instruction to cancel the conversion is received, the character string is extracted again from the kana character string storage section 41a and is displayed on the display means 42. When replacing and conversion is unconfirmed, the cursor is moved in the direction of the beginning or end of the sentence in response to instructions from the keyboard 40, and when canceling the conversion, the cursor is moved toward the beginning of the sentence in response to instructions from the keyboard 40. , it is moved in units of clauses, and in the direction of the end of the sentence, it is moved to the end of the cancellation range.

Next, the operation of the above embodiment will be explained according to the flowchart shown in FIG.

The processing from step 80 to step 86 in the figure is the same as the operation of the second embodiment of the invention, so the explanation will be omitted. When the function cursor movement key is pressed following step 84 (step 100), the input editing processing section 70
Step 101) to determine whether c is in an undetermined state.
If it is in an undetermined state, it is further determined whether it is in a canceled state (step 102).

If it is in the cancellation state, check the M type of the cursor movement key (step 103), and if it is the day key, move the cursor to the end of the cancellation range (step 104).
, and if it is the day key, the cursor is moved to the break of the phrase on the left (step 105).

The range to which the cursor has moved becomes the cancellation range.

In addition, if the state is not canceled in step 102, that is, the state is unconfirmed, and if it is a day key, the cursor is moved to the bunsetsu break on the right (step 108-10).
7) If it is a day key, move it to the next bunsetsu break on the left (steps 106-108).This allows you to move the cursor in both directions for each bunsetsu, so it is possible to move the cursor in both directions for clauses that have not been properly converted. The cursor movement required when converting the next candidate is performed efficiently.

Also, if it is not in an undetermined state at step lot,
Step IQ9) to determine the type of cursor movement key
, if it is a day key, the cursor is moved to the end of the line (step 110), and if it is a day key, the cursor is moved to the beginning of the line (step 1ll).

(g) Effects of the Invention According to the first invention, when the desired sentence cannot be obtained in the conversion, the operator can change the break position of the clause in the conversion process, thereby improving the efficiency of the conversion process. be able to.

Furthermore, according to the second invention, in the state of cancellation of conversion, the cursor can be moved toward the end of the sentence in units of clauses, so the number of operations for moving the cursor is reduced, and the efficiency of reconversion is improved. can be improved.

Further, according to the third invention, in the undetermined state, the cursor can be moved in the direction of the beginning of the sentence and the end of the sentence, in units of clauses, and in the canceled state, the cursor can be moved in the direction of the beginning of the sentence, in units of clauses, and in the direction of the end of the sentence. In the direction, you can jump to the end of the undo range, so if an incorrect conversion occurs, you can quickly move the cursor to that location, and in the undo state, you can correct the clause that caused the incorrect conversion. After doing so, you can move the cursor all at once to the end of the undo range and reconvert.
