Detailed Description of the Invention

[0001]

The present invention relates is related to conversion control method in character processing apparatus and a character processing apparatus for converting by referring to the dictionary the character string input to the kanji kana Pepper string.

[0002]

2. Description of the Related Art As a conventional document processing apparatus, there is a technology of directly inputting a Chinese character string by handwriting with a pen. However, in the case of directly inputting a kanji, there is a case where the user forgets the kanji to input and cannot remember it, or there is a kanji that is troublesome to write. In such a case, the character may be handwritten in a kana.

There is also a technique of inputting a kana by handwriting pen input or the like and converting it into kanji by kana-kanji conversion. In this case as well, it is easier to input the kanji as it is rather than write it in hiragana. , It may be difficult to recognize some kana characters, so you may want to input by handwriting in kanji.

For example, the user wants to input "Katarin" and convert it into "Katarin".

There are mainly the following two methods as a method of inputting a character string containing kanji and kana and converting it into an appropriate kanji character string.

The first method is disclosed in JP-A-62-20966.
As described in Japanese Patent Laid-Open No. 7, the kanji-kana-combination conversion is performed by having a dictionary of kanji-kana-combination headings and a corresponding kanji description. For example, in the case of "Katarin", a method is to have a dictionary containing the heading "Katarin" and the corresponding Kanji notation "Katarin".

The second method is disclosed in JP-A-63-37465.
As described in the official gazette, by having a dictionary that converts kanji into kana, it converts kanji in the input character string into kana and performs normal kana-kanji conversion for the corrected kana character string. It is a thing. For example, in the case of "Katarin,""Kata" is converted into the kana "Hen, Katata,""Henrin,Katarin" is converted into Kana-Kanji, and "Katascale" that matches the input character string is used as a candidate. is there.

[0008]

As described above, it may be easier to write a character by handwriting with a pen, when writing a combination of hiragana and kanji, and writing the hiragana part in katakana. For example, instead of writing “meeting”, it is desirable to input “meeting” and convert it to “meeting”. This is because katakana is usually more linear than hiragana, it is easy to input by handwriting, and the number of strokes is often small.

However, in the case of performing kanji-kana mixing conversion by using a conventional kanji-kana mixing heading and a dictionary of kanji notation corresponding to it, since a heading such as "kaigi" is not usually included in the heading, it is called "meeting". It cannot be converted.

Further, by having a dictionary for converting kanji into kana, the kana of the input character string is converted into kana and the kana-kanji conversion can be performed normally for the corrected kana character string. If you read it in Hiragana, it may be erroneously converted.

For example, suppose that the sentence "local Xiamen city" is entered as "Jiyuan Xiamen Shino" to convert kanji and kana. If this "Amoi" is an unregistered word and is not in the dictionary, if you simply correct katakana to Hiragana, you can use "Local Amo Ishino", "Local Amo Ishino", "Local Amo Ishino", " There is a possibility that it will be converted such as "Local Ammo Ishino".

[0012]

The present invention has been made for the purpose of solving the above problems. In the present invention, kanji and hiragana are used.

In FIG. 1, according to the present invention, a CPU 1 for controlling the entire apparatus, a ROM 2 for storing a control program for controlling the CPU, a RAM 3 for storing various data,
It is composed of a ROM 4 for storing dictionary data and a grammar table necessary for conversion, a tablet 5, an LCD 6, and a controller 7. The ROM 2 stores a dictionary search program, a katakana analysis program, a conversion device program, and the like. The RAM 3 stores the input character string, stores temporary data in the middle of conversion, and stores the conversion result. The tablet 5 is transparent and is a coordinate detection device that detects characters handwritten with a pen or the like as coordinate data. The LCD 6 is a display device that displays a text creation / editing screen, a character input result, and the like. Controller 7
Controls the tablet 5 and the LCD 6. Tablet 5
The controller 7 corresponds to the input device, and the LCD 6 and the tablet 7 correspond to the output device.

<Embodiment 1> Referring to FIG. 2, the apparatus of the first embodiment has an input unit (11), a Katakana replacement unit (12), a Katakana analysis unit (13), a dictionary 1 (14), and a switch (15). ), A conversion unit (16), a dictionary 2 (17), and an output unit (18).

The input unit (11) is for inputting a character string mixed with Kana and Kana by a handwriting input device, etc., and the Katakana replacement unit (12) is judged by the Katakana analysis unit (13) to be not Katakana (originally Hiragana). Characters are replaced with katakana from hiragana, and the katakana analysis unit (13) analyzes whether the characters input in katakana are originally katakana or the places in hiragana are input in katakana. The dictionary 1 (14) is necessary for performing katakana analysis, and the switch (1
5) is katakana replacement (12) and katakana analysis (13)
The conversion unit (1
6) is for converting a character string containing kanji and kana into an appropriate character string, the dictionary 2 (17) is necessary for conversion by the conversion unit (16), and the output unit (18) is The converted character string is output to an LCD or the like.

In this embodiment, the katakana analysis unit (13) determines whether or not there is a word including all katakana continuous character strings. Dictionary 1 in this case
(14) may be only the heading portion of the dictionary 2 (17) used at the time of conversion.

Next, the processing of the first embodiment will be described with reference to FIG.
This will be described with reference to the flowchart of FIG. Step 101
Is a process for inputting a character string including kanji and kana from the input unit (11). In step 102, the switch (15) is O
N (You can use katakana to input in hiragana)
Or OFF (if you enter in Hiragana, you cannot enter in Katakana). If ON (YES), the process proceeds to step 103, and if OFF (NO), the process proceeds to step 108. Step 103 is a process of extracting a continuous katakana portion of the input character string. Step 104 is a process for replacing katakana with hiragana.
Step 105 is a process of checking whether or not it matches the dictionary 1 (14). If it matches (YES)
Moves the process to step 107, and if there is no match (N
O) shifts the processing to step 106. Step 106 is a process of replacing the hiragana part replaced in step 104 with katakana again. Step 107 is a process of checking whether there is another continuous katakana part.
If there is (YES), the process returns to step 103, and if there is no (NO), the process moves to step 108. Step 108 is a process of converting kanji and kana. However, the part returned to katakana in step 106 is not converted as a conversion target. Step 109 is Step 10
This is a process of outputting the character string converted in 8.

Next, an actual input character string will be described as an example. First, the case where "Meeting" is input will be described. The input character string "kaigi" is input from the input unit (11) (step 101). It is judged whether or not the switch (15) is ON (step 102), and now the switch (15).
Is ON (YES), the katakana continuous part is extracted from the input character string (step 103). In this case, "gi" is taken out. Next, katakana is replaced with hiragana (step 104). In this case, the input character string is "meeting". Then, it is checked whether or not there is a word including the katakana continuous part "Gi" in the dictionary 1 (14) (step 105). Now, assume that the heading of the dictionary 1 (14) is as shown in FIG. Now, the word "meeting" is found in the dictionary headline, and since there is a match (YES), the process proceeds to step 107. In step 107, it is checked whether there is another katakana sequence (step 107). Since there is nothing else in this case, the process is moved to step 108, and conversion is performed by the conversion unit (16) (step 108).
The target character string is now "meeting" and is converted to "meeting". The "conference" is output to the output unit (18) (step 109).

Next, description will be made on the case where "the original Amoy Shino" is input. The input character string "The original Amoy Shino" is input from the input unit (11) (step 101). It is determined whether the switch (15) is ON (step 10
2) Since the switch is now ON (YES), the Katakana continuation part is extracted from the input character string (step 10).
3). In this case, "ji" is taken out. Next, katakana is replaced with hiragana (step 104). in this case,
The input character string becomes "Jigen Amoy Shino". Then, it is checked whether or not there is a word including the katakana continuous part "ji" in the dictionary 1 (14) (step 105). Now that the dictionary has "jimoto", it will match (YES)
The processing moves to step 107. In step 107, it is checked whether or not there is another katakana sequence (step 107). In this case, since there is still more, the process is returned to step 103.

In step 103, the continuous katakana part is extracted (step 103). In this case, "AMOY" is taken out. Next, katakana is replaced with hiragana (step 104). In this case, the input character string is "Jijimoto Amoishino". Then, it is checked whether or not there is a word including the katakana continuous part "AMOY" in the dictionary 1 (14) (step 105). Since it is not in the dictionary now (NO), the process is moved to step 106. Then, the portion replaced with hiragana in step 104 is replaced with katakana again (step 106). In this case, the input character string becomes "Same original Amoy Shino". In step 107, it is checked whether there is another katakana sequence, and in this case, it is not (N
O), the process moves to step 108. Step 108
Then, "Amoi" is converted into Katakana and a candidate "Local Amoy City" is obtained (Step 1
08). Then, the "Local Amoy City" is output (18)
(Step 109).

By thus performing the katakana analysis, more accurate conversion can be performed. Also, by enabling a switch to allow or disallow katakana crosswriting, it is possible to input with a high degree of freedom in modes that allow katakana crosswriting, and eliminate incorrect conversion due to katakana in modes that do not allow katakana crosswriting. Therefore, highly accurate conversion is possible.

<Embodiment 2> In FIG. 5, the apparatus of the second embodiment has an input unit (21), a conversion unit (22), a dictionary lookup unit (23), a Katakana analysis unit (24) and a dictionary (25). ), A switch (26) and an output section (27).

The input unit (21) is for inputting a character string of kanji and kana mixed with a handwriting input device or the like, and the conversion part (22) is for converting the input character string of kanji and kana mixed into an appropriate character string. The dictionary lookup unit (23) is included in the conversion unit (22), and is characterized in that it draws a character string with kanji and kana without distinction between Katakana and Hiragana. The Katakana analysis unit (24). Is to analyze whether the characters entered in katakana are originally katakana or whether the characters in hiragana are entered in katakana. The dictionary (25) is a dictionary lookup (23) and a katakana analysis part (24). And the conversion unit (22) requires the entire process, and the switch (26) draws the process of the dictionary lookup unit (23) without distinguishing Katakana and Hiragana, or the Katakana analysis unit (24). A switch for switching whether to perform processing, the output unit (27) and outputs the converted string like the LCD.

Next, the processing of the second embodiment will be described with reference to FIG.
This will be described with reference to the flowchart of FIG. Step 201
Is a process for inputting a character string containing kanji and kana. In step 202, it is determined whether the switch is ON (where hiragana can be input in katakana) or OFF (where hiragana can be entered in katakana). If it is ON (YES), move the process to step 203 and turn it OFF.
If (NO), the process moves to step 207. In step 203, the dictionary is searched for the input character string without distinguishing between katakana and hiragana. Specifically, it is assumed that the character string handled in the conversion process is managed by the JIS code, and when looking up a dictionary, if it is hiragana or katakana, only the lower byte is searched. (Hiragana is 0x24 in JIS code.
??, Katakana is 0x25 ??, and the same character has the same low-order byte. For example, "Gi" is 0x242E, "Gi" is
It is 0x252E. ) Step 204 is a process for checking whether or not the searched word includes all katakana continuation parts. If included (YES), the process proceeds to step 205, and if not included (NO), the process proceeds to step 206. In step 205, the word retrieved in step 204 is used as a word candidate for the conversion process in step 207, and RA
This is a process of saving in M3. In step 206, the word retrieved in step 204 is not left as a word candidate in the conversion process in step 207. Step 207 is a process for converting kanji and kana. However, the words stored in the RAM in step 205 are candidates for conversion. Step 208 is step 20
This is a process of outputting the character string converted in 7.

Next, an actual input character string will be described as an example. The case where "Meeting" is input will be described. The input character "kaigi" is input by the input unit (21) (switch 201). It is determined whether the switch (26) is ON (step 202), and now the switch (26) is ON.
Therefore, (YES), the dictionary is looked up without distinguishing katakana and hiragana from the input character string (step 20).
3). It is assumed that the dictionary (25) has the same heading as in FIG. The input character string is "kaigi" and the JIS code "0x3271,"
"0x252E", but hiragana (higher byte 0x24) and katakana (higher byte 0x25) are searched by lower byte only, so the dictionary heading "Meeting" (JIS code "0x327"
1, 0x242E ”). It is checked whether the word retrieved in step 203 includes all katakana continuation parts of the input character string (step 204). Now, the katakana continuous part is "Gi" and includes all (YES)
The process moves to step 205. In step 205, the word "meeting" retrieved in step 204 is used as a word candidate,
It is stored in the RAM 3 (step 205). Step 20
In step 5, the kanji and kana are converted using the words stored in the RAM 3 as candidates and converted into a character string "meeting" (step 207). Then, the "conference" is output to the output unit (27).

By performing katakana analysis in this way, more accurate conversion can be performed. Also, by enabling a switch to allow or disallow katakana crosswriting, it is possible to input with a high degree of freedom in modes that allow katakana crosswriting, and eliminate incorrect conversion due to katakana in modes that do not allow katakana crosswriting. Therefore, highly accurate conversion is possible.

<Embodiment 3> In FIG. 7, the apparatus of the third embodiment has an input unit (31), a Katakana recognition unit (32), a conversion unit (33), a dictionary (34) and an output unit (35). Composed of and.

The input unit (31) is for inputting a character string mixed with Kana and Kana using a handwriting input device or the like, and marks katakana that is not converted. The katakana recognition unit (3)
In 2), among the input character strings, the one with a mark is originally katakana, and the part without a mark is judged to have been inputted with hiragana, and the conversion part (33) is A dictionary (34) is for converting an input character string into an appropriate character string on the premise of the unconverted katakana part recognized by the katakana recognition part (32).
Is necessary for conversion by the conversion unit (33), and the output unit (35) outputs the converted character string to an LCD or the like.

Next, the processing of the third embodiment will be described with reference to FIG.
This will be described with reference to the flowchart of FIG. Step 301
Is a process for inputting a character string including kanji and kana from the input unit (31). Step 302 is a process of inputting a katakana that is not converted, that is, an underline “_” in this embodiment. Step 303 is a process of recognizing the underline input in step 302 and determining a conversion target. Step 304 is a process of converting the input character string into an appropriate character string on the assumption that the part other than the part recognized in step 303 is converted. As the conversion including the katakana part, either the method of replacing katakana with hiragana in the first embodiment or the method of searching the dictionary without distinguishing katakana and hiragana in the second embodiment may be used. Step 305 is a process of outputting the character string converted in step 304.

Next, an actual input character string will be described as an example. The case where "the original Amoy Shino" is input will be described. The input character string "The original Amoy Shino" is input (step 301). Underline "AMOY" as katakana that is not converted (step 302). FIG. 10 shows this state. The underline of "AMOY" is recognized (step 303), and it is determined that "AMOY" is not converted. Assuming that the characters other than "Xiamen" recognized in step 303 are converted, kanji and kana will be converted into "local Xiamen city" (step 30).
4). "Local Amoy City" is output to the output unit (35) (step 305).

By marking katakana that is not converted in this way, erroneous conversion associated with katakana input can be eliminated, and highly accurate conversion can be realized.

In the above, the katakana not to be converted is marked, but the katakana to be converted may be marked. As shown in FIG. 8, the device in that case has an input section (41) and hiragana. It is composed of a recognition unit (42), a conversion unit (43), a dictionary (44), and an output unit (45). The input unit (41) is for inputting a character string with kanji and kana using a handwriting input device or the like, and marks the katakana to be converted, and the hiragana recognition unit (42) is for inputting a character string in the input character string. The ones marked with are the ones entered in hiragana in katakana, and the ones not marked are to be judged as katakana originally, and the conversion part (43) is recognized by the hiragana recognition part (42). The input character string is converted into an appropriate character string on the premise of the katakana part to be converted, and the dictionary (44) is a conversion part (4
This is necessary when performing the conversion of 3), and the output section (4
In 5), the converted character string is output to an LCD or the like.
