Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kana-kanji conversion system, and more particularly to a kana-kanji conversion system used in word processors, personal computers, electronic notebooks, portable information terminals, POS terminals and the like.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Laid-Open No. 62-10763, a user can arbitrarily set a phrase range by using a phrase movement key, a phrase expansion key and a phrase reduction key provided on a keyboard. You can move it, stretch the phrase,
I am reducing the clause. For example, if "Ishii Fukushachosama" is entered, the conversion key is pressed, and "Ishii Copy Survey Ma" is displayed, the user can see that the copy has one phrase. "Fuck"
To shorten the phrase to "Fuku" → "Sub", use the phrase reduction key to change "Fukusha" to "Fukusha".
At this time, if "Fuku" has been converted into another homonym "Clothing", the conversion key is pressed several times to change from "Clothing" to "Sub". In order to read "sha" as "shachu", operate the phrase expansion key to change the phrase to "shachu". Then, the first notation "President" is displayed. Furthermore,
As for "Kuma", the bunsetsu is divided into "sa" and "ma", so the bunsetsu decompression key is operated to make the bunsetsu "sama". Then, the first notation "sama" is displayed. As a result, the sentence "Vice President Ishii" is obtained.

Recently, a word processor that can use a mouse has been put into practical use. For example, "I went to the doctor today"
If the text "Today's dentist" is pressed after the conversion key is pressed and the text "Today's dentist" is read, the user moves the cursor to the beginning of "Today" and instructs conversion again. Then, move the cursor to the end point "teeth" of the phrase and press the execute key. Then, the kanji is returned to Hiragana and "Kyohaissha nikita" is displayed. In addition,
The part that has been returned to hiragana is displayed in black and white or knitted, and the user moves the cursor between “ha” and “i” and presses the conversion key. Then you will get "I went to visit today". At this time, "Isha ni" is still displayed in black and white, or knitting or the like is still displayed, and the user moves the cursor between "ni" and "row" and presses the conversion key. Then you get "I went to the doctor today".

[0004]

As described above, in the conventional kana-kanji conversion system, the bunsetsu to be corrected starts to be corrected from the length of the bunsetsu determined by the system such as "copy" or "survey magic". , The system is pushing the phrase decided by the system, and the user judges how the system decides the division position and length of the phrase, and then moves the phrase, performs the phrase expansion / contraction process, and the re-conversion process to avoid erroneous conversion. It has to be corrected and it doesn't match the user's feeling. Also, even in a word processor that can use a mouse, the system returns to Hiragana for each punctuation unit of the phrase, so there is no merit of specifying the range with the mouse.

Furthermore, when the sentence "My neighbor's daughter is crying because her cat is dead." Is entered, the words "daughter" and "crying" are separated, so "crying" Follow the character string and find the subject "cat"
"The next daughter is crying because my cat is dead. ) Is likely to be output as a conversion, and the input character string is apt to cause incorrect conversion because it cannot correctly recognize the co-occurrence relationship between clauses.

The present invention has been made in order to solve the above problems, and the displayed contents can be corrected within the character range as the user feels, and the phrase accompanying the correction of erroneous conversion can be corrected. The purpose is to provide a kana-kanji conversion system that can perform conversion that matches the user's feeling without thinking about the definition, and that can recognize distant character strings as physically adjacent phrases and easily generate correct answer candidates. To do.

[0007]

According to the present invention, the above-mentioned object is to convert Japanese readings into kanji-kana mixed sentences based on phrase information by inputting kana or romaji and searching a word dictionary. A pen-operable kana-kanji conversion system for recognizing an input character string and a display means for displaying a converted character string, and recognizing the displayed converted character string traced by a pen, If only the recognized character string is restored to the original kana and is subject to re-conversion, and the part restored to the above kana is traced again with the pen, the characters that are not duplicated are not converted into the kana as they are. The kana-kanji conversion system according to claim 1, further comprising a target pen operating means.

According to the present invention, for the above-mentioned object, the pen operation means recognizes the erroneously converted character string by designating a start point and an end point with the pen, and uses the recognized character string as an original kana. 3. A character that has not been designated in duplicate is designated as a non-conversion target when the start point and the end point are designated again in the part that has been restored and re-converted into the kana. It is achieved by the Kana-Kanji conversion system described in.

According to the present invention, for the above-mentioned object, the pen operation means automatically recognizes a phrase including a character traced by the pen, and after the entire recognized phrase is subjected to reconversion, 4. The phrase reduction function is operated when is moved to the left, and the phrase expansion function is activated when the pen is moved to the right, and the reduced or expanded range is reconverted. Achieved by the Kana-Kanji conversion system.

According to the present invention, for the above-mentioned object, when the pen operation means operates the phrase reduction function or the phrase expansion function, and the pen is moved upward, the object to be reconverted is 1. It is achieved by the kana-kanji conversion system according to claim 4, recognizing that it is limited to bunsetsu and recognizing that the re-conversion target is not limited to one bunsetsu when the pen is moved downward.

According to the present invention, for the above-mentioned object, the pen operation means, when a plurality of ranges to be re-converted are designated by the pen, also uses the co-occurrence relationship to target the distant phrases. This is achieved by the Kana-Kanji conversion system described in 5.

According to the present invention, the above-mentioned object is to determine whether the pen operating means measures the distance between the character traced by the pen and the break of the phrase, and expands or contracts the break position on the left side of the phrase. The kana-kanji conversion system according to claim 6, which determines whether to expand or contract the break position on the right side of the phrase.

[0013]

In the kana-kanji conversion system according to claim 1, the converted kanji-kana mixed sentence is displayed on the display means, and the pen recognizes the traced character string displayed on the display means. Only the recognized character string is restored to the original kana regardless of the clause information and is subject to re-conversion, and when the part restored to the kana is traced again with the pen, the characters that are not duplicated with the pen are The pen operation means does not change the kana as it is. This simplifies the operation of correcting the incorrect conversion, and the displayed content can be corrected within the character range as the user feels, without having to think about the definition of the clause accompanying the correction of the incorrect conversion. You can perform conversion that matches the user's feeling.

In the kana-kanji conversion system according to claim 2, when the start point and the end point of the erroneously converted character string are designated by the pen by the pen operation means, the character string between them is recognized as an erroneously converted character, When the recognized character string is restored to the original kana string and is subject to re-conversion, and the start point and end point are specified again in the part restored to the kana character, the characters that are not duplicately specified are Kana remains as it is and is not converted. This can further simplify the operation when the erroneously converted character string is long.

In the kana-kanji conversion system according to claim 3, the pen operation means automatically recognizes a phrase including a character traced by the pen, and the entire phrase is targeted for re-conversion. Is moved to the left, the bunsetsu reduction function is operated, and when the pen is moved to the right, the bunsetsu decompression function is operated, and the reduced or expanded range is reconverted. This simplifies the range designation operation when the erroneous conversion range is one phrase.

In the kana-kanji conversion system according to the fourth aspect, when the pen is moved upward when the bunsetsu reduction function or bunsetsu expansion function is operated by the pen operation means, the re-conversion target is 1 It is recognized that it is limited to a phrase, and when the pen is moved downward, it is recognized that the reconversion target is not limited to one phrase. As a result, the operation of specifying the segment break can be simplified.

In the kana-kanji conversion system according to the fifth aspect, when a plurality of ranges for re-conversion are designated by the pen by the pen operating means, bunsetsus apart by utilizing the co-occurrence relation are also targets for conversion. It As a result, distant character strings can be recognized as physically adjacent phrases, correct answer candidates can be easily provided, and conversion that matches the user's feeling can be performed.

In the kana-kanji conversion system according to claim 6, the position of the character traced by the pen and the distance between the punctuation marks are measured by the pen operating means, and the left punctuation position of the bunsetsu is expanded or contracted. Is determined or whether the segmentation position on the right side of the clause is expanded or contracted. As a result, the left end of the phrase can be expanded or contracted, and the operation of designating the break position of the phrase can be simplified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First embodiment of the kana-kanji conversion system of the present invention.
An example of the above will be described with reference to the drawings.

The kana-kanji conversion system of this embodiment is shown in FIG.
As shown in FIG. 2, a control unit 1 including a microprocessor, a program, a table, an external storage device, and the like, and controlling each unit, and a CRT or LC for displaying a sentence mixed with Kanji and Kana.
A display unit 2 as a display unit composed of D, an input unit 3 for inputting characters and the like, a dictionary unit 4 for storing independent words, proper nouns, affixes, phonological dictionaries, user dictionaries, etc., and co-occurrence relation of words The example dictionary unit 5 for storing the example dictionary indicating the above is provided, and the buffer 6 for storing the input characters, the converted characters, and the like. The input unit 3 includes a tablet 33 that detects the XY coordinates of the display unit 2, a pen 31 that indicates an arbitrary position of the tablet 33, and a keyboard 32 that inputs characters and the like.
The buffer 6 includes an input character buffer 61, a conversion character buffer 62, a learning buffer 63, a homophone word buffer 64, a sentence buffer 65, and a screen buffer 6.
It is composed of 6.

The pen operating means includes a control unit 1 and a tablet 3.
3 and a pen 31.

The input character buffer 61 is a buffer for storing characters input from the input unit 3. The converted character buffer 62 is a buffer for storing the first candidate data when the data in the input character buffer 61 is converted. If there is a confirmed homophone, the learning buffer 63
This is a buffer for increasing the priority. The homophone word buffer 64 is a buffer that stores homophone words other than the first candidate in the converted character buffer 62 and other word data created during the conversion process. The text buffer 65 is a buffer that stores the confirmed text data. The screen buffer 66 has a form in which the input character buffer 61 or the converted character buffer 62 and the sentence buffer 65 are combined, and the buffer information of the input character buffer 61 and the converted character buffer 62 is also provided in the screen buffer 66.

Next, the operation of this embodiment will be described.

The kana string input from the input unit 3 is first stored in the input character buffer 61. Then, when it comes to the conversion timing, the control unit 1 refers to the dictionary unit 4, the example dictionary unit 5, and other tables to perform the Kana-Kanji conversion process, and the conversion character buffer 62 stores the first priority candidate. Further, the word data different from the word data other than the first priority candidate is stored in the homophone word buffer 64, is displayed on the display unit 2 by the operation of the input unit 3, and can be selected. When a homophone is selected by operating the input unit 3, the result is stored in the learning buffer 63. The determined text data is copied from the converted character buffer 62 to the text buffer 65.

For example, the contents of the respective data buffers 61 to 66 immediately after the character string “Kinenshi Tenkaisai” is actually input and converted in the middle of the text data “64th / preparatory meeting” As shown in FIG. The relationship between the input character buffer 61 and the conversion character buffer 62 is that reading information for each character of the conversion character string is stored in the conversion character buffer 62. The relationship between the input character buffer 61 and the homophone word buffer 64 is as follows:
That is, the word information when the phrase starts from that is stored in the homophone word buffer 64. If there is no undetermined character string in the screen buffer 66, the contents of the sentence buffer 65 are output as they are, and if there is an undetermined character string before conversion, the input character buffer 61 is inserted at the cursor position of the sentence buffer 65 and output. If there is an undetermined character string after conversion, the converted character string data is inserted at the cursor position of the text buffer 65 and output. In this case, information about where in the screen buffer 66 the undetermined character string is stored.

Next, an example of erroneous conversion correction will be described with reference to the flowchart of FIG.

When the character string "today" is input from the keyboard 32 of the input unit 3, the character string "today" is entered in the input character buffer 61 as shown in FIG. Is stored in the converted character buffer 62
Stores "today / to dentist / go", and the homophone buffer 64 contains the same phoneme for "today", the same phoneme for "dentist", and the same phoneme for "go".
Other candidates are stored, “Today / To dentist / I went” is stored in the screen buffer 66, and “Today / Today / To dentist” is stored in the display unit 2.
"I went to the dentist / I went there" is displayed. Note that the slash (/) represents a segment break and is not output in the actual display.

When the user traces the "today's tooth" portion with the pen 31 (step S1), it is determined by the controller 1 whether or not the unfixed character string in the screen buffer 66 has been traced (step S2). . When it is determined that the undetermined character string in the screen buffer 66 has been traced, the control unit 1 searches the undetermined character in the screen buffer 66 for the same character string in the converted character buffer 62 (step S3). If the same character string does not exist, an error will occur. When the same character string is found, the input character buffer 61 shown in FIG.
The hiragana character “Kyohaisha nikita” shown in FIG. 4A is taken out, and the character “Kyoto Tooth” traced by the pen 31 from the converted character string in the converted character buffer 62 is shown in FIG. 4B.
As shown in (4), it is returned to the hiragana "Kyoha" (step S4). The converted character buffer 62 stores “Today was a doctor / I went”. The "Kyoha" portion is shaded to indicate that it is traced by the pen 31. The contents of the converted character buffer 62 in which the characters traced by the pen 31 have been returned to the hiragana character are copied to the screen buffer 66 (step S).
5). The display unit 2 displays “Today I went to a doctor / I went”. The "Kyoha" portion is shaded to indicate that it is traced by the pen 31.

When the user presses the conversion key (step S6), the character string returned to hiragana is retrieved from the homophone word buffer 64 for word information satisfying the conditions (step S6).
7). If there is word information satisfying the condition, the corresponding word is set in the converted character string of the converted character buffer 62, and the reading character number information is also reset (step S8). Then, the conversion character string "I went to the doctor today" is set in the screen buffer 66 (step S10), and "Today went to the doctor / I went" is displayed on the display unit 2. If there is no word information that meets the conditions, the kana-kanji conversion process is performed again from the hiragana "Kyohaisha nikita", and the conversion character string buffer 6 is output from the homophone word buffer 64 or by the conversion process.
2 is updated and the reading character number information is also set (step S9).

In the above-mentioned embodiment, the "tooth today" is traced by the pen 31, but only the "tooth" is pen 3.
If traced with 1, the conversion work of “Kyoha” is not necessary and the number of operations can be reduced.

Now, another input example will be described.

When "Please remove kimono here" is input and the conversion key is pressed, "Here / take off / take off" is displayed. Therefore, the user uses the pen 3
When you trace "footwear" by 1, "Here / Footwear /
Please take it off ”is displayed. The “footwear” portion is shaded to indicate that it has been traced by the pen 31. Further, when the user traces the “kimono” with the pen 31, “Please remove / wear / remove kimono” is displayed. The “kimono” portion is a shaded display showing that it has been traced by the pen 31. If you trace the character string returned to hiragana again with the pen 31, only the duplicated character string will be converted.
Character strings that have not been traced are excluded from conversion. Then, when the user presses the conversion key, "here / wa / take off / take off" is displayed. Next, a second embodiment of the kana-kanji conversion system of the present invention will be described. The kana-kanji conversion system has the same configuration as that shown in FIG.

The feature of this embodiment is that the pen 31 designates the erroneously converted character string at the start point and the end point. This eliminates the need to trace the erroneously converted character string from the beginning to the end, improving operability.

When the starting point and the ending point of the erroneously converted character string are designated by the pen 31, only the character string is restored to the original hiragana string regardless of the clause information by the control unit 1 and is subject to re-conversion. . Further, when the start point and the end point are designated again by the pen 31, the characters not designated in duplicate are left as hiragana and are not converted. The control unit 1 determines whether or not the undetermined character string in the screen buffer 66 is designated. When it is determined that the undetermined character string in the screen buffer 66 is designated, the control unit 1 searches the undetermined character in the screen buffer 66 for the same character string in the converted character buffer 62. If the same character string does not exist, an error will occur. If the same character string is found, the hiragana character of the input character buffer 61 is extracted from the reading character information and converted character buffer 6
The character designated by the pen 31 is returned to the hiragana from the converted character string of 2. The contents of the conversion character buffer 62 in which the character designated by the pen 31 is returned to the hiragana are copied to the screen buffer 66. Then, when the user presses the conversion key, the homophone buffer 6 is added to the character string returned to the hiragana.
Word information that meets the conditions is searched from 4. When there is word information that meets the conditions, the corresponding word is converted character buffer 62.
Is set in the conversion character string of, and the reading character number information is also reset. Then, the conversion character string is set in the screen buffer 66. Also, if there is no word information that meets the conditions,
The hiragana-kanji conversion process is performed again, the conversion character string buffer 62 is updated from the homophone buffer 64 or by the conversion process, and the reading character number information is also set.

For example, when "now" and "tooth" in "Today / Visit / Dentist" are touched with the pen 31,
"Today / I went to the doctor / I went" is displayed. In addition,
The "Kyoha" portion is shaded to indicate that it has been designated by the pen 31. Further, instead of the characters themselves, the space between the characters may be designated.

Next, a third embodiment of the kana-kanji conversion system of the present invention will be described. The kana-kanji conversion system has the same configuration as that shown in FIG.

The feature of the present embodiment is that the bunsetsu of the character designated by the pen is automatically recognized, the whole bunsetsu is targeted for reconversion, and when the pen is moved to the left, the bunsetsu reduction function is performed. When the pen is moved to the right, the phrase decompression function works and the reduced or expanded range is subject to reconversion.

For example, the pen 31 touches the "today" portion of the "today" character string of "today / dentist / go". Then, “Today / I went to the dentist / I went” is displayed. The "today" portion is shaded to indicate that it has been designated by the pen 31. Pen 3
If the user moves to the right with 1 left, it is determined that the control unit 1 has instructed the expansion process, and "Kyoha / Doctor / Go" is displayed. The "Kyoha" part is a pen 3
The screen is shaded to indicate that it is designated by 1. Then, when the conversion key is pressed, "Kyoha" is converted, and "Today / To doctor / I went" is displayed.

Next, a fourth embodiment of the kana-kanji conversion system of the present invention will be described. The kana-kanji conversion system has the same configuration as that shown in FIG.

The feature of this embodiment is that when the phrase reduction function or the phrase expansion function is activated, if the position of the pen is before the cursor position of the screen buffer after being specified by the pen,
It is recognized that the target of reconversion is limited to one phrase, and if the pen position is after the cursor position, the pen position is
It is to be recognized that the reconversion target is a compound clause.

When the bunsetsu is extended as in the third embodiment described above, if the pen 31 is raised upward, the re-conversion target is 1
If it is limited to a phrase and the pen 31 is lowered downward, it is recognized that the target character string for reconversion is not necessarily one phrase.

For example, as shown in FIG. 6, "Keep usual" is input, the conversion key is pressed, "Always / Kawahara / Contents / Yes" is displayed, and then " The portion of the character string "Kawara" is touched with the pen 31. Then, "Always / Kara / Content / Yes" is displayed. The "kawara" portion is shaded to indicate that it has been designated by the pen 31. Pen 3
When 1 is moved to the right while it is left, it is determined that the decompression processing has been instructed by the control unit 1, and "Always / Do not change / do" is displayed. Note that the portion of "Never change" is still displayed as a shaded display indicating that it has been designated by the pen 31. When the pen 31 is moved further to the right, "Do / Change / Always" is displayed. As shown in Fig. 7, "Do not change"
The portion marked with is still in the shaded display indicating that it has been designated by the pen 31. If you move the pen 31 up,
"Do not change" is recognized as one phrase. As a result, the control unit gives priority to one phrase candidate. Then, when the conversion key is pressed, the conversion processing "Keep it unchanged" is performed and "Always / Do not change / Perform" is displayed.

Next, a fifth embodiment of the kana-kanji conversion system of the present invention will be described. The kana-kanji conversion system has the same configuration as that shown in FIG.

The operation of this embodiment will be described with reference to the flowchart of FIG.

The character string "Dog is crying beside my son is laughing" is input from the keyboard 32 of the input unit 3, and the user uses the pen 31 to "cry dog".
After tracing the two phrase portions of (step S11), the control unit 1 determines whether or not the undetermined character string in the screen buffer 66 has been traced (step S12). When it is determined that the undetermined character string in the screen buffer 66 has been traced,
The control unit 1 searches the unconfirmed character in the screen buffer 66 for the same character string in the converted character buffer 62 (step S13). If the same character string does not exist, an error will occur. If the same character string is found, the hiragana character "Inu ga my musume is not yoko ni wa ni" which is shown in FIG. 8A of the input character buffer 61 is taken out from the reading character information, and the conversion character buffer 62 is converted. The characters "dog" and "crying" traced from the character string with the pen 31 are shown in FIG.
As shown in (b), the hiragana "Inu ga" and "I have no"
(Step S14). Converted character buffer 62
"The dog is not beside my son laughing."
Is stored. The "inu ga" and "absent" portions are shaded to indicate that they are traced by the pen 31. The contents of the converted character buffer 62, in which the characters traced by the pen 31 have been returned to the hiragana character, are copied to the screen buffer 66, "the dog is not lying next to my son laughing" (step S15). Then, when the user presses the conversion key (step S16), it is checked whether or not there are a plurality of character strings returned to hiragana, and if there is one phrase, the homophone word buffer 64 is searched for word information satisfying the condition. In addition, if it is a compound phrase, that phrase "Inu ga""I am not"
Are adjacent to each other, and a combination of words that meet the conditions is searched from the example dictionary unit 5 (step S17). "animal"
From the combination of + “crowing”, “dog” and “crowing” are derived. If there is word information that meets the conditions, the corresponding word is set in the converted character string of the converted character buffer 62, the read character number information is reset, and the read character number information is also set (step S18). Then, the conversion character string "Dog is crying beside my son laughing" is set in the screen buffer 66 (step S20), and "Dog crying beside my son is laughing" is displayed on the display unit 2. Is displayed. If there is no word information that meets the conditions, the Hiragana to Kana-Kanji conversion process is performed again, and the homophone buffer 6
4 or from the conversion processing, the conversion character string buffer 62 is updated, and the reading character number information is also set (step S19).

Next, a sixth embodiment of the kana-kanji conversion system of the present invention will be described. The kana-kanji conversion system has the same configuration as that shown in FIG.

The feature of the present embodiment is that the distance between the character position traced by the pen 31 and the break of the phrase is measured by the control unit 1, and the break position on the left side of the phrase is expanded or contracted or the position on the right side of the phrase is changed. It is to decide whether to extend or contract the break position.

As in the third embodiment described above, the pen 31 somewhere in the character string of "today" of "today / dentist / go"
When touched by, the distance between the position touched with the pen and the left and right breaks of the phrase is measured, and whether the break position on the left side of the phrase or the break position on the right side of the phrase is expanded or contracted is controlled. Judged by 1.

For example, when the "tooth" position of "Today / To dentist / I went" is touched with a pen, the control unit 1 determines that the division position of "Today / Dentist" is corrected from the distance, and "Today.""/ Haisasha / I went" is displayed. In addition, the portion of "Haisha ni" is a shaded display indicating that it is designated by the pen 31. When the pen 31 is moved to the right, the phrase reduction function is activated and "Today / Issha / I went" is displayed. Note that the "Isha ni" portion remains in a shaded display indicating that it has been designated by the pen 31. Then, when the conversion key is pressed, "issha ni" is converted, and "Today / I went to the doctor / I went."
Is displayed. The reason is that "tooth" is to be changed to "ha", and in the present embodiment, only the left side of the phrase was expanded or contracted, but the right side of the specified phrase can be expanded or contracted.

It is possible to perform the operation of this embodiment in the same manner with a mouse. However, when the mouse and the pen are compared, the mouse cannot move the cursor position from the screen, but in the case of the pen, the cursor does not move. There is an advantage that the position can be directly moved to a desired position and specified without moving the position on the screen.
