Abstract

(57) [Summary] A desired conversion candidate is obtained by using both pinyin input and double pinyin input without switching input modes. An input unit is provided in a double pinyin input mode.
When a read character string to be converted is input by the following, the double read-in / pin-in replacement unit 25 replaces the input read character string with pinyin. At that time, the input control processing unit 22
Checks whether the read character string after replacement conforms to the Pinyin rule, and if the character string does not conform to the Pinyin rule, assumes that it was input by Pinyin and returns to the state at the time of input. The conversion unit 23 converts the read character string returned to the state at the time of input into Chinese, and outputs the conversion candidate by the output unit 26. Thus, in the double pinyin input mode, a desired conversion candidate can be obtained even if a reading character string is input in pinyin.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Chinese input conversion device such as a Chinese word processor used for creating a Chinese document, and more particularly to a reading method using two input modes of pinyin input and double pinyin input. The present invention relates to a Chinese input conversion processing device suitable for use in inputting a Chinese character, a Chinese input conversion processing method used in the Chinese input conversion processing device, and a recording medium recording a Chinese input conversion processing program.

[0002]

2. Description of the Related Art Chinese input methods can be broadly classified into two methods: an input method using character information (character input method) and an input method using character information (character input method). The former character shape information is information obtained from the shape of a kanji, and corresponds to a radical, a stroke, the number of strokes, and the like. The latter character information is information obtained from reading a kanji.
In the syllabary input method, vowels, syllables, rhymes, tones obtained by phonetically decomposing kanji readings, and syllabic information including combinations of these are often used.

At present, the former character-shape input method is popular, but the demand for a character-sound input method suitable for inputting while considering a sentence by oneself has been increasing recently. The phonetic input method mainly uses a phonetic symbol called pinyin, which represents all Chinese syllables using 26 letters of the alphabet and u and e.

That is, in Chinese, the pronunciation of one kanji is always one syllable. One syllable further includes a leading consonant called "vowel" (a consonant at the beginning of the syllable),
It is composed of parts excluding "vowels" called "final vowels" (including vowels, diphthongs, nasal vowels, etc.). There is also a tone called "four voices" (similar to Japanese accent) which represents the inflection of a syllable, and one syllable is composed of three elements, a vowel, a final and a four voice.

Examples of vowels: b, p, m, f, d, t, n,
l, zh, ch, sh,... Examples of rhyme: a, o, e, i, u, ai, en, ang,
ong,... The character input method is a method of inputting such a voice and a final in pinyin. Since Pinyin can be learned in basic education in recent years, it can be said that the Pinyin input method is easy to learn.

However, in the case of pinyin input, a large number of keys must be input to input one syllable, so that there is a problem that input efficiency is poor. For example, if you input a syllable with pinyin to convert it to “floor”, “chua”
ng "and 6 keys.

To solve this problem, a method called double pin-in input has been proposed. The double pinyin input method is a method in which one key is assigned to each of vowels and finals, which are syllable elements, and one syllable is input with two keys. Using this double pinyin input, the "floor"
Is input by inputting "uh" and 2 keys.

The voice of "chuang" is "c".
h, the final is “uang”. In the case of double pinyin input, the initial “ch” is assigned to the “u” key of the first keystroke, and “uang” is assigned to the final of the “h” key of the second keystroke. I have. Therefore, “chuang” can be input with “uh”.

[0009]

As described above, double pinyin input requires only two keys to input one syllable.
For this reason, if the user learns the double pinyin input, the input efficiency will be greatly improved.

[0010] However, since the phonetic symbol has few chances to be in contact with each other, the rule may be forgotten and the input may take time. In such a case, it is sufficient to switch to the normal pinyin input only for the forgotten portion, but switching between modes is also troublesome because it takes time and effort.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and provides a Chinese input system capable of obtaining a desired conversion candidate by using both pinyin input and double pinyin input without switching input modes. An object of the present invention is to provide a conversion medium, a Chinese input conversion method, and a recording medium on which a Chinese input conversion processing program is recorded.

[0012]

That is, according to a first aspect of the present invention, there is provided a Chinese input conversion processing apparatus comprising: a mode setting means for setting a pinyin input mode or a double pinyin input mode; In the state where the input mode is set, input means for inputting a reading character string to be converted, replacement means for replacing the reading character string input by the input means with Pinyin, and replacement with Pinyin by the replacement means Pinyin rule checking means for checking whether or not the read character string conforms to the Pinyin rule. If the result of the Pinyin rule check means does not conform to the Pinyin rule, it is deemed to have been input in Pinyin, Replacement return means to return the column to the state at the time of input, reading of Pinyin notation and corresponding heading A conversion for searching the Chinese dictionary based on the registered Chinese dictionary and the reading character string returned to the state at the time of input by the replacement return unit, and extracting a heading corresponding to the reading character string as a conversion candidate Means, and output means for outputting a conversion candidate obtained by the conversion means.

According to such a configuration, when there are two input modes, the pinyin input mode and the double pinyin input mode, the read character string to be converted is input while the double pinyin input mode is set. Then, the input reading character string is replaced with Pinyin.
At that time, it is checked whether or not the replaced read character string conforms to the Pinyin rule. If the character string does not conform to the Pinyin rule, the character string is assumed to have been input by Pinyin and the state at the time of input is returned. Then, a Chinese dictionary is searched based on the read character string returned to the state at the time of input, and a heading corresponding to the read character string is extracted as a conversion candidate. Therefore, in the double pinyin input mode, a desired conversion candidate can be obtained even if a reading character string is input in pinyin.

According to a second aspect of the present invention, there is provided a Chinese input conversion processing device, wherein a mode setting means for setting a pinyin input mode or a double pinyin input mode, and the pinyin input mode is set by the mode setting means. In the state, input means for inputting a reading character string to be converted, a Chinese dictionary in which reading of Pinyin notation and a corresponding heading are registered, and the Chinese character string based on the reading character string input by the input means. A conversion means for searching a word dictionary and extracting a heading corresponding to the read character string as a conversion candidate; and, if no conversion candidate is obtained by the conversion means, it is regarded as having been input by double pinyin. Replacement means for replacing the column with pinyin,
A conversion control unit that supplies the read character string replaced by Pinyin to the conversion unit and performs a conversion process again; and an output unit that outputs a conversion candidate obtained by the conversion unit. And

According to such a configuration, when there are two input modes, the pinyin input mode and the double pinyin input mode, a read character string to be converted is input in a state where the pinyin input mode is set. Then, a Chinese dictionary is searched based on the input reading character string, and a heading corresponding to the reading character string is extracted as a conversion candidate. At that time, if it is not obtained as a conversion candidate, it is assumed that it has been input in double pinyin, the read character string is replaced with pinyin, and the conversion process is performed again based on the read character string after this replacement. Therefore, in the pinyin input mode, a desired conversion candidate can be obtained even if a reading character string is input by double pinyin.

According to a third aspect, in the first aspect, when a conversion candidate is not obtained by the conversion means, the input character string is divided into a pinyin on the front side and a double pinyin on the rear side. Reading division means;
A conversion control unit that gives the Pinyin part of the read character string divided by the reading division unit to the conversion unit and performs conversion again, and replaces the double Pinyin part with Pinyin and then gives the conversion unit and performs conversion again. It is characterized by having.

According to such a configuration, when the reading input in the double pinyin input mode does not conform to the pinyin rules, and a conversion candidate is not obtained even if the dictionary is referred to as being input in pinyin For example, by dividing and converting the reading with the front side being pinyin and the rear side being double pinyin, conversion candidates can be obtained even in the double pinyin input mode even if the reading character string includes pinyin on the front side.

According to a fourth aspect of the present invention, in the first aspect, when a conversion candidate is not obtained by the conversion means, the input character string is divided into a double pinyin on the front side and a pinyin on the rear side. Reading division means;
Conversion control means for replacing the double pinyin part of the read character string divided by the reading division means with pinyin, and then giving it to the conversion means for conversion again, and giving the pinyin part to the conversion means for conversion again. And characterized in that:

According to such a configuration, when a reading input in the double pinyin input mode does not conform to the pinyin rules, and a conversion candidate is not obtained even if the dictionary is referred to as being input in pinyin For example, split the reading with the front side as double pinyin and the back side as pinyin,
By converting, in double pinyin input mode,
Conversion candidates can be obtained even for a read character string in which pinyin is mixed on the front side.

According to a fifth aspect, in the third or fourth aspect, there is provided a reading position correcting means for correcting the reading position of the pinyin portion and the double pinyin portion divided by the reading dividing means. And

According to such a configuration, when the position of the double pinyin and the pinyin determined by the system are incorrect, the user can arbitrarily correct the position and follow the corrected position. Conversion candidates can be obtained.

According to a sixth aspect, in any one of the first to fifth aspects, when a conversion candidate is not obtained by the conversion means, the read character string is converted to hiragana, and It is characterized by having a hiragana conversion means for outputting.

According to such a configuration, if a conversion candidate is not obtained even when the input read character string is replaced with Pinyin or Double Pinyin, the read character string is finally replaced with Hiragana. Is output. Thus, even when the pinyin input mode or the double pinyin input mode is set, it is possible to input hiragana without switching the input mode.

According to a seventh aspect of the present invention, in any one of the first to fifth aspects, the final output character designating means for designating the type of the final output character and the conversion means failing to obtain a conversion candidate. And a character type conversion means for converting the read character string into a character type designated by the final output character designation means and outputting the converted character string as a final character.

According to such a configuration, by specifying the type of the final output character in advance, if a conversion candidate is not obtained even when the input read character string is replaced with pinyin or double pinyin, The read character string is finally replaced with the specified character type and output. Thus, even when the pinyin input mode or the double pinyin input mode is set, a desired character type can be input without switching the input mode.

Next, the functional configuration of the Chinese input conversion processing device realized by the system configuration shown in FIG. 1 will be described. FIG. 2 is a block diagram showing a functional configuration of the Chinese input conversion processing device realized by the system configuration of FIG. As shown in FIG. 2, the Chinese input conversion processing device according to the present embodiment includes an input unit 21, an input control processing unit 22,
It has a conversion unit 23, a Chinese dictionary 24, a double pinyin / pinyin replacement unit 25, and an output unit 26.

The input unit 21 inputs a character string to be converted, a conversion instruction, and the like. The input control processing unit 22 receives and manages information input from the input unit 21. The input control processing unit 22 stores an input mode buffer 22 for storing the currently set input mode (pinyin input mode / double pinyin input mode).
a, a pinyin rule table 22b storing pinyin rules (see FIG. 6), a readout character string buffer 22c for storing a readout character string input by pinyin or double pinyin, and finally if no conversion candidate is obtained, And a final output character buffer 22d for storing the type of the character to be output to the printer.

The input control processing section 22 calls the double pinyin / pinyin replacement section 25 and replaces the read character string input in double pinyin with the character string in pinyin, and vice versa. A process of replacing the read character string with a double pinyin character string is performed. Also,
A control key such as a conversion key is also accepted, and if it is a conversion key, the conversion unit 23 is called to perform a Chinese conversion process.

Hereinafter, the reading input in Pinyin is referred to as Pinyin reading, and the reading input in Double Pinyin is referred to as Double Pinyin reading. The conversion unit 23 refers to the Chinese dictionary 24 and converts the Pinyin reading received from the input control processing unit 22 into Chinese kanji. In the Chinese dictionary 24, information such as reading of Chinese Pinyin notation, heading (Chinese kanji), and part of speech are registered for each word (see FIG. 3).
This word dictionary 24 is used as a standard dictionary in the external storage device 15.
Is stored in

The double pinyin / pinyin replacement section 25
It has a double pinyin rule table 25a that stores a double pinyin rule (see FIG. 7) in which pinyin and double pinyin are associated, and under the control of the input control processing unit 22,
Replacing a double pinyin reading character string with a pinyin reading character string or replacing a pinyin reading character string with a double pinyin reading character string.

The output unit 26 displays the input Pinyin or Double Pinyin character string, conversion candidates corresponding to the input Pinyin or Double Pinyin character string, and the like.
4 for output processing.

FIG. 3 shows the structure of the Chinese dictionary 24. In the Chinese dictionary 24, information necessary for the Pinyin kanji conversion processing, such as Chinese Pinyin reading, headline, part of speech, and the like, is registered for each word. In the example of FIG.
A Chinese kanji character such as “slumber” is registered as a heading with the reading “itonang”. Also, "ke
A Chinese kanji such as "Kado" is registered as a heading with the reading "tang." In the Chinese dictionary 24, all readings are registered in pinyin.

Here, the pinyin will be briefly described. In Chinese, phonetic symbols called Pinyin are used to represent Chinese sounds. Pinyin is alphabet 2
It represents all Chinese syllables using 6 letters and u and e. One syllable is basically “vowel” and “final”
Consists of The "vowel" is a consonant at the beginning of a syllable, and 21 types are defined as shown in FIG.
The “final” is a part of the syllable excluding the vowel, and FIG.
As shown in the table, 35 types are defined (actually, there are er and the like).

In Chinese sounds, one syllable generally consists of a combination of one vowel and one rhyme, but there are some combinations that are impossible in practice, so there are about 400 types. FIG.
Shows some syllable types consisting of a combination of the initial and final. The combination indicated by “○” in the figure is used as a standard Chinese standard tone. FIG. 6 shows only a part of the combinations, but there are actually many more combinations.

In the Pinyin rule table 22b of FIG. 2, the combination of the initial and the final used as such Chinese standard sounds is stored in advance as the Pinyin rule. When inputting Chinese kanji readings in Pinyin, it is necessary to input in accordance with the Pinyin rules.

On the other hand, there is an input method called double pinyin, which is different from the input method by pinyin. This is a method in which one key is assigned to each of the initials and finals, which are syllable elements, and one syllable is input with two keys. For example, in Pinyin, the initial of "chuang" is "ch" and the final is "uang", but in double Pinyin, the initial "u" key is the initial key "ch" and the second key is the "h" key. "Uang" is assigned to the rhyme mother. for that reason,
"Chug" can be input with "uh".

FIG. 7 shows a part of the combination of the initial and final by double pinyin. In the double pinyin rule table 25a, a combination of the initial and final by such double pinyin is stored in advance as a double pinyin rule. When inputting Chinese kanji reading with double pinyin, it is necessary to input according to this double pinyin rule.

Next, the conversion processing operation according to the first embodiment of the present invention will be described. Conventionally, the pinyin input and the double pinyin input are separated according to the mode, and if a pinyin is input in the double pinyin input mode, only an erroneous input has occurred.

Therefore, in the first embodiment, when the input double pinyin does not conform to the pinyin rule, the pinyin is converted assuming that it has been input, so that pinyin and double pinyin can be performed without switching the input mode. Can be used together.

FIG. 8 is a flowchart showing a conversion processing operation according to the first embodiment of the present invention. First, the double pinyin input mode is selected as the input mode (step A11). It is assumed that the user can arbitrarily select an input mode (a pinyin input mode / a double pinyin input mode) on, for example, an environment setting screen (not shown). The input mode selected here is the input mode buffer 22a of the input control processing unit 22.
Is held.

Here, as shown in FIG. 9A, if a character string such as "chentong" is inputted as a reading from the input unit 21 (Yes in step A12),
The input control processing unit 22 stores the read character string in the read character string buffer 22c (Step A13). The reading here is double pinyin reading according to the currently set input mode.

After the reading and input, if there is a conversion instruction by pressing the conversion key (Yes in step A14), the input control processing section 22 sends the input read character string to the double pinyin / pinyin replacement section 25, and sends it to the pinyin. The character string of the reading is replaced (step A15).

In this case, the double pinyin / pinyin replacement unit 25 converts the input reading character string "chentong" into the pinyin reading according to the double pinyin rule stored in the double pinyin rule table 25a as shown in FIG. 9B. Replace with a character string such as "ciangiutonang". The double pinyin rule is, as shown in FIG. 7, a character (a, b, c...) Assigned to each of a vowel and a final, which are syllable elements, and an actual pinyin character string corresponding to the combination of the characters. It summarizes the rules for

The input control processing section 22 converts the read character string replaced with the Pinyin reading into the Pinyin rule table 22b.
(Step A16). The pinyin rules are, as shown in FIG. 6, a set of rules relating to pinyin such as a possible initial and final.

As a result, if the reading character string conforms to the Pinyin rule (Yes in step A16), the input control processing unit 22 assumes that the reading has been input by double pinyin as in the input mode, and Leave it replaced with Pinyin reading. On the other hand, if the read character string does not conform to the Pinyin rule (No in step A16), the input control processing unit 22 returns the read character string to the state at the time of input (the character string before replacement with Pinyin). (Step A1
7).

In the example of "ciangiutonang", since [c + ian] is a non-combinable voice and a final, it can be determined that the input reading character string has been input in a pinyin different from the input mode (double pinyin). . Therefore, as shown in FIG. 9C, the read character string after the replacement is the read character string “chenton” at the time of input.
g ".

The read character string thus obtained is passed to the converter 23. The conversion unit 23 converts the read character string into Chinese kanji by referring to the Chinese dictionary 24 and extracting a heading corresponding to the read character string (step A1).
8).

In this case, when the Chinese dictionary 24 is searched for “chentong”, “slumber” is present as a heading. Therefore, as shown in FIG. Display (Step A1
9).

As described above, when the input double pinyin does not conform to the pinyin rule, the conversion is performed assuming that the pinyin is input, so that a desired conversion candidate can be obtained without switching the input mode. it can.

(Second Embodiment) Next, a conversion processing operation according to a second embodiment will be described. In the second embodiment, when there is no conversion candidate in the input pinyin, it is assumed that the input is the double pinyin and the conversion is performed, so that the pinyin and the double pinyin can be used together without switching the input mode. Things.

FIG. 10 is a flowchart showing a conversion processing operation according to the second embodiment of the present invention. First, a pinyin input mode is selected as an input mode (step B11). It is assumed that the user can arbitrarily select an input mode (a pinyin input mode / a double pinyin input mode) on, for example, an environment setting screen (not shown). The input mode selected here is held in the input mode buffer 22a of the input control processing unit 22.

Here, as shown in FIG. 11A, when "ketg" is input from the input unit 21, the input control processing unit 22 stores the read character string in the read character string buffer 22c (step S11). B13). The reading here is a pinyin reading according to the currently set input mode.

After reading and input, when there is a conversion instruction by pressing the conversion key (Yes in step B14), the input control processing unit 22 passes the input read character string to the conversion unit 23. The conversion unit 23 refers to the Chinese dictionary 24 and extracts a heading corresponding to the read character string, thereby converting the read character string into Chinese kanji (step B15).

If there is a conversion candidate (step B1)
6), the conversion candidates are displayed on the screen through the output unit 26 (step B18). On the other hand, if there is no corresponding conversion candidate (No in step B16), the input control processing unit 22 determines that the input read character string is double pinyin reading, and converts the read character string to double pinyin /
It is sent to the pinyin replacement section 25 and replaced with pinyin reading (step B17).

In the case of "ketg", no conversion candidate is obtained because it is not registered in the Chinese dictionary 24. Therefore,
The reading is sent to the double pinyin / pinyin replacement unit 25, and as shown in FIG.
g ".

When the pinyin reading is obtained, the conversion process is performed again by the conversion unit 23 (step B15). In this case, if the Chinese dictionary 24 is searched for “ketang”, a conversion candidate such as “kadou” is obtained.
As shown in (c), the conversion candidates are displayed on the screen.

As described above, when there is no conversion candidate in the input pinyin, the conversion is performed assuming that the input is the double pinyin, so that a desired conversion candidate can be obtained without switching the input mode.

(Third Embodiment) Next, a conversion processing operation according to a third embodiment will be described. In the double pinyin input mode, when a plurality of syllables are successively input, there is a possibility that pinyin may be mixed and input due to inputting of the reading in double pinyin, which is an abbreviation.
In the pinyin input mode, since pinyin input is premised, there is little possibility that double pinyin, which is an abbreviation, is mixed and input.

Therefore, in the third embodiment, in the double pinyin input mode, if a conversion candidate is not obtained even if a reading input by double pinyin is regarded as input by pinyin and conversion is not performed, the input is performed. It is assumed that Pinyin is mixed in the front side of the read character string, and the reading is divided into Pinyin on the front side and Double Pinyin on the back side, and the conversion is performed again.

FIG. 12 is a flowchart showing the conversion processing operation according to the third embodiment of the present invention. First, the double pinyin input mode is selected as the input mode (step C11). It is assumed that the user can arbitrarily select an input mode (a pinyin input mode / a double pinyin input mode) on, for example, an environment setting screen (not shown). The input mode selected here is the input mode buffer 22 of the input control processing unit 22.
a.

Here, as shown in FIG. 13A, assuming that “tianqhrhd” is input from the input unit 21 (Yes in step C12), the input control processing unit 22
Holds the read character string in the read character string buffer 22c (step C13). The reading here is double pinyin reading according to the currently set input mode.

After the reading and input, if there is a conversion instruction by pressing the conversion key (Yes in step C14), the input control processing unit 22 sends the input reading character string to the double pinyin / pinyin replacement unit 25, and this is input. Replace with a reading character string (step C15).

In this case, the double pinyin / pinyin replacement unit 25 converts the input character string “tianqhrhrd” into the pinyin reading as shown in FIG. 13B in accordance with the double pinyin rule stored in the double pinyin rule table 25a. Replace with a character string such as "tianqihenhao".

The input control processing section 22 converts the read character string replaced with the Pinyin reading into the Pinyin rule table 22b.
(Step C16).

As a result, if the reading character string conforms to the Pinyin rule (Yes in step C16), the input control processing unit 22 assumes that the reading has been input by double pinyin as in the input mode, and converts the reading character string. Leave it replaced with Pinyin reading. On the other hand, if the read character string does not conform to the Pinyin rule (No in step C16), the input control processing unit 22 returns the read character string to the state at the time of input (the character string before replacement with Pinyin). (Step C1
7).

In the example of “tianqihenhao”,
Since [a + n] is a non-combinable initial and final, it can be determined that the input reading character string has been input in a pinyin different from the input mode (double pinyin input mode). Therefore, as shown in FIG. 13C, the read character string after replacement is the read character string “tianq” at the time of input.
ihrhd ”.

The read character string thus obtained is passed to the conversion unit 23. The conversion unit 23 refers to the Chinese dictionary 24 and extracts a heading corresponding to the read character string, thereby converting the read character string into Chinese kanji (step C1).
8).

If there is no heading corresponding to the Chinese dictionary 24 and no conversion candidate is obtained (step C1).
9), the input control processing unit 22 shortens the end of the read character string by one character (step C20), and then performs the Chinese conversion process again through the conversion unit 23 (step C1).
8). This process is repeated until a conversion candidate is obtained.

In this case, in the example of “tianqhrhd”, there is no conversion candidate since the information of the word is not registered in the Chinese dictionary 24. Therefore, "tianqih
rhd ”to“ tianqi ”. Thereby, as shown in FIG. 13D, the conversion candidate “weather” is obtained and displayed on the screen through the output unit 26 (step C).
21).

When all the readings have been converted, the process ends. if,
If there are any remaining readings (Yes in step C22), it is assumed that the reading in this portion has been input by double pinyin as in the input mode. Therefore, after the remaining portion is replaced with Pinyin reading through the double Pinyin / Pinyin replacement unit 25 (Step C23), the conversion is performed in Chinese through the conversion unit 23 (Step C24), and the conversion candidates are also displayed (Step C25). .

In the above example, the remaining readings are “hrhd”
It is. When this is replaced with Pinyin reading, FIG.
As shown in (e), it is "henhao". As a result, "great" is obtained from the Chinese dictionary 24, and FIG.
As shown on the screen.

As described above, when the reading input in the double pinyin input mode does not conform to the pinyin rules and the conversion candidate is not obtained even if the dictionary is referred to as the pinyin input, for example, By dividing and converting the reading as Pinyin and the back side as Double Pinyin,
In the double pinyin input mode, conversion candidates can be obtained even for a read character string in which pinyin is mixed on the front side.

(Fourth Embodiment) Next, a conversion processing operation according to a fourth embodiment will be described. As described above, in the double pinyin input mode, when a plurality of syllables are input consecutively, there is a possibility that pinyin may be mixed and input due to inputting in the abbreviated form double pinyin. There is. In the pinyin input mode, since pinyin input is premised, there is little possibility that double pinyin, which is an abbreviation, is mixed and input.

Therefore, in the fourth embodiment, in the double pinyin input mode, if a conversion candidate is not obtained even if the reading input by double pinyin is converted assuming that it is input by pinyin, the input is not performed. It is assumed that Pinyin is mixed on the back side of the read character string, and the reading is divided into Double Pinyin on the front side and Pinyin on the back side, and the conversion is performed again.

FIG. 14 is a flowchart showing a conversion processing operation according to the fourth embodiment of the present invention. First, the double pinyin input mode is selected as the input mode (step D11). It is assumed that the user can arbitrarily select an input mode (a pinyin input mode / a double pinyin input mode) on, for example, an environment setting screen (not shown). The input mode selected here is the input mode buffer 22 of the input control processing unit 22.
a.

Here, as shown in FIG. 15A, if "tjqihenhao" is input from the input unit 21 (Yes in step D12), the input control processing unit 22
Holds the read character string in the read character string buffer 22c (step D13). The reading here is double pinyin reading according to the currently set input mode.

After the reading and input, when there is a conversion instruction by pressing the conversion key (Yes in step D14), the input control processing unit 22 sends the input reading character string to the double pinyin / pinyin replacement unit 25, and this is input. Replace with a reading character string (step D15).

In this case, the double pinyin / pinyin replacement unit 25 converts the input reading character string “tjqihenhao” into the pinyin reading in accordance with the double pinyin rule stored in the double pinyin rule table 25a as shown in FIG. Replace with a read character string such as "tianqiheniango".

The input control processing unit 22 converts the read character string replaced with the Pinyin reading into the Pinyin rule table 22b.
(Step D16).

In the case of “tianqiheniangao”, since there is no part that does not conform to the Pinyin rule (Yes in step D16), the read character string after the replacement is
3 and the Chinese dictionary 24 is checked (step D17).

If there is no heading corresponding to the Chinese dictionary 24 and no conversion candidate is obtained (step D1).
No. 8), the input control processing unit 22 shortens the read character string by one character from the end (step D20), and performs the Chinese conversion process again through the conversion unit 23 (step D2).
1). This process is repeated until a conversion candidate is obtained.

In this case, "tianqiheniang"
In the example of "ao", there is no conversion candidate because the information of the word is not registered in the Chinese dictionary 24. Therefore, "ti
"anqiheniangao" is shortened to "tianqi". As a result, as shown in FIG. 15C, the conversion candidate “weather” is obtained and displayed on the screen through the output unit 26 (step D22).

When all the readings have been converted, the process ends. if,
If there is any remaining reading (Yes in step D23), this part is regarded as having been pin-in input. Then, after returning to the original reading (step D24), it is converted into Chinese through the conversion unit 23 (step D25), and the conversion candidate is displayed together (step D26).

In the above example, the remaining readings are "henia
ngao ”, and when the original reading at the time of input is returned, FIG.
As shown in (d), it becomes "henhao". As a result, “great” is obtained from the Chinese dictionary 24, and FIG.
As shown on the screen.

As described above, when the reading input in the double pinyin input mode does not conform to the pinyin rules, and the conversion candidate is not obtained even if the dictionary is referred to as the pinyin input, for example, The double pinyin,
By dividing and converting the reading with the back side being pinyin, in the double pinyin input mode, conversion candidates can be obtained even if the reading character string includes pinyin on the front side.

(Fifth Embodiment) Next, a conversion processing operation according to a fifth embodiment will be described. In the fifth embodiment, when the input reading character string is automatically divided as in the third or fourth embodiment, the reading position can be arbitrarily corrected by the user.

FIG. 16 is a flowchart showing a conversion processing operation according to the fifth embodiment of the present invention. Note that the description here is based on the fourth embodiment. The processing in steps E11 to E26 in the figure is the same as the processing in steps D11 to D26 in FIG.

That is, first, the double pinyin input mode is selected as the input mode (step E1).
1). It is assumed that the user can arbitrarily select an input mode (a pinyin input mode / a double pinyin input mode) on, for example, an environment setting screen (not shown). The input mode selected here is held in the input mode buffer 22a of the input control processing unit 22.

Here, as shown in FIG. 15A, if "tjqihenhao" is input from the input unit 21 (Yes in step E12), the input control processing unit 22
Holds the read character string in the read character string buffer 22c (step E13). The reading here is double pinyin reading according to the currently set input mode.

After the reading and input, if there is a conversion instruction by pressing the conversion key (Yes in step E14), the input control processing section 22 sends the input reading character string to the double pinyin / pinyin replacement section 25, and this is input. Replace with a reading character string (step E15).

In this case, the double pinyin / pinyin replacement unit 25 converts the input reading character string “tjqihenhao” into the pinyin reading in accordance with the double pinyin rule stored in the double pinyin rule table 25a as shown in FIG. Replace with a read character string such as "tianqiheniango".

The input control processing section 22 converts the read character string replaced with the Pinyin reading into the Pinyin rule table 22b.
(Step E16).

In the case of “tianqiheniangao”, since there is no part that does not conform to the Pinyin rule (Yes in step E16), the read character string after the replacement is
3 and the Chinese dictionary 24 is checked (step E17).

Here, when there is no heading corresponding to the Chinese dictionary 24 and no conversion candidate is obtained (step E1).
No. 8), the input control processing unit 22 shortens the read character string by one character from the end (step E20), and then performs the Chinese conversion process again through the conversion unit 23 (step E2).
1). This process is repeated until a conversion candidate is obtained.

In this case, "tianqiheniang"
In the example of "ao", there is no conversion candidate because the information of the word is not registered in the Chinese dictionary 24. Therefore, "ti
"anqiheniangao" is shortened to "tianqi". Thereby, as shown in FIG. 15C, the conversion candidate “weather” is obtained and displayed on the screen through the output unit 26 (step E22).

When all readings have been converted, the process ends. if,
If there is any remaining reading (Yes in step E23), it is regarded that this part has been pin-in input. Then, after returning to the original reading (step E24), it is converted into Chinese through the conversion unit 23 (step E25), and the conversion candidates are displayed together (step E26).

In the above example, the remaining readings are "henia
ngao ”, and when the original reading at the time of input is returned, FIG.
As shown in (d), it becomes "henhao". As a result, “great” is obtained from the Chinese dictionary 24, and FIG.
As shown on the screen.

Here, in the fifth embodiment, after "weather" and "greatly good" are displayed as described above, a key for correcting the reading length (separation position) is accepted (step E27). In the above example, the first input reading character string “tj
Of the “qihenhao”, it was assumed that up to “tjqi” was input in double pinyin and “henhao” was input in pinyin, but as shown in FIG. 17A, the portion input by the user in double pinyin was “tjqi”. Suppose that the part input in Pinyin is corrected to "qihenhao".

When the length of double pinyin and pinyin reading is changed (Yes in step E28), the input control processing section 22 re-cuts the read character string at a specified position, and uses the re-cut position as a reference. Double pinyin on the front side
The Chinese language conversion is performed again with the rear side being pinyin (step E29).

In this case, as shown in FIG. 17 (b), the reading part on the front side is replaced by the pinyin reading "tian" by the double pinyin / pinyin replacement unit 25 and then converted into Chinese. As a result, as shown in FIG. 17C, a conversion candidate such as “heaven” is obtained. Also, the back side is converted to Chinese as it is, as shown in FIG.
A conversion candidate such as “Place of Place” as shown in FIG.

As described above, when the position of the double pinyin and the pinyin determined by the system are incorrect, the user can arbitrarily correct the position and obtain a conversion candidate according to the corrected position. Will be able to do it.

Note that such correction of the reading position is also applicable to the third embodiment. When applied to the third embodiment, by adding the processing of steps E27 to E29 after the processing of step C25 in FIG. 12, the read character string is re-cut according to the position designated by the user, The Chinese conversion may be performed again with the front side being pinyin and the back side being double pinyin.

(Sixth Embodiment) Next, a conversion processing operation according to a sixth embodiment will be described. In the sixth embodiment, in the above first to fourth embodiments, when the input read character string cannot be converted even if it is replaced with Pinyin or Double Pinyin, the input read character string is replaced with "Hiragana". Things.

FIG. 18 is a flowchart showing a conversion processing operation according to the sixth embodiment of the present invention. Note that the description here is based on the first embodiment. The processing in steps F11 to F18 in the drawing is the same as the processing in steps A11 to A18 in FIG.

That is, in the state where the double pin-in input mode is selected (step F11), for example, FIG.
As shown in (a), it is assumed that a reading character string such as "kounotori" is input and conversion is instructed (steps F12 to F14). In response to the conversion instruction, the double pinyin / pinyin replacement unit 25 replaces the read character string with pinyin reading (step F15), and then the input control processing unit 2
2. Compare with Pinyin rule in Step 2 (Step F1)
6).

As a result, if the reading character string conforms to the Pinyin rule (Yes in step F16), the input control processing unit 22 assumes that the reading has been input by double pinyin as in the input mode, and Leave it replaced with Pinyin reading. On the other hand, if the read character string does not conform to the Pinyin rule (No in step F16), the input control processing unit 22 returns the read character string to the state when it was input (the character string before replacement with Pinyin). (Step F1
7).

In the above example, as shown in FIG. 19B, the input reading character string “kounotori” is changed to “kuotori”.
uiengensh ”. In the example of "kuouiuengensh", [u +
iu] is an uncombinable initial and final, so that it can be determined that the input reading character string has been input in a pinyin different from the input mode (double pinyin input mode). Therefore, as shown in FIG. 19C, the read character string after replacement is the read character string “kounotor” at the time of input.
i ".

The read character string thus obtained is passed to the conversion unit 23. The conversion unit 23 converts the read character string into Chinese kanji by referring to the Chinese dictionary 24 and extracting a heading corresponding to the read character string (step F1).
8).

Here, in the sixth embodiment, if there is a conversion candidate (Yes in step F19), the input control processing unit 22 displays the conversion candidate on the screen via the output unit 26 (step F21).

On the other hand, if there is no conversion candidate (step F1)
9), the input control processing unit 22 determines that Roman characters have been input, replaces the read character string with hiragana (step F20), and displays this (step F2).
1).

In the above example, since "kounotori" is not registered in the Chinese dictionary 24, it is considered that Roman characters have been input. As a result, as shown in FIG. 19 (d), "Konotori" replaced with Hiragana characters is displayed on the screen.

As described above, in the double pinyin input mode, when a conversion candidate is not obtained even when the input reading character string is replaced with the pinyin reading, the conversion is performed by regarding the input as a Roman character. Hiragana can be input without switching the input mode.

Note that such substitution with hiragana is also applicable to the second to fourth embodiments. That is,
In each embodiment, if a conversion candidate is not obtained even when the input reading character string is replaced with Pinyin or Double Pinyin, the input reading character string is replaced with Hiragana as a final Roman character input. What is necessary is just to add processing.

(Seventh Embodiment) Next, a conversion processing operation according to a seventh embodiment will be described. In the sixth embodiment, the input character string is replaced with "Hiragana" when conversion is not possible even if it is replaced with Pinyin or Double Pinyin. Can be arbitrarily selected by the user such as “Hiragana”, “Katakana”, “Alphabet”, and the like.

FIG. 20 is a flowchart showing a conversion processing operation according to the seventh embodiment of the present invention. Note that the description here is based on the first embodiment. The processing of steps G11 and G13 to G19 in the figure is the same as in FIG.
Is the same as the processing of steps A11 to A18.

That is, while the double pinyin input mode is selected (step G11), the final output character is selected (step G12). The final output characters are "Hiragana", "Katakana", "Alphabet"
And the user can arbitrarily select from these. The type of the character selected here is held in the final output character buffer 22d of the input control processing unit 22.

Here, for example, as shown in FIG. 21 (a), it is assumed that a reading character string such as "kounotori" is input and conversion is instructed (steps G13 to G1).
5). According to the conversion instruction, the read character string is replaced with the Pinyin reading by the double Pinyin / Pinyin replacement unit 25 (step G16), and the input control processing unit 22 compares the read character string with the Pinyin rule (step G17).

As a result, if the reading character string conforms to the Pinyin rule (Yes in step G17), the input control processing unit 22 assumes that the reading has been input in double pinyin as in the input mode, and Leave it replaced with Pinyin reading. On the other hand, if the read character string does not conform to the Pinyin rule (No in step G17), the input control processing unit 22 returns the read character string to the state at the time of input (the character string before replacement with Pinyin). (Step G1
8).

In the above example, as shown in FIG. 21B, the input read character string “kounotori” is changed to “kuotori”.
uiengensh ”. In the example of "kuouiuengensh", [u +
iu] is an uncombinable initial and final, so that it can be determined that the input reading character string has been input in a pinyin different from the input mode (double pinyin input mode). Therefore, as shown in FIG. 21C, the read character string after replacement is the read character string “kounotortor” at the time of input.
i ".

The read character string thus obtained is passed to the conversion unit 23. The conversion unit 23 refers to the Chinese dictionary 24 and extracts a heading corresponding to the read character string, thereby converting the read character string into Chinese kanji (step G1).
9).

Here, in the seventh embodiment, if there is a conversion candidate (Yes in step G20), the input control processing unit 22 displays the conversion candidate on the screen via the output unit 26 (step G22).

On the other hand, if there are no conversion candidates (step G2
(No of 0), the input control processing unit 22 replaces the read character string with the final output character designated by the user based on the character type held in the final output character buffer 22d (step G21), and displays it. (Step G22).

In the above example, since “kounotori” is not registered in the Chinese dictionary 24, it is replaced with the designated character. In this case, for example, when “Katakana” is selected as the final output character, FIG.
As shown in Fig. 7, after the Roman character conversion, the "stork" further replaced by katakana characters is displayed on the screen.

As described above, if "Katakana" is previously selected as the final output character, "kounotori" input by double pinyin or pinyin is replaced by katakana "stork". Similarly, "Hiragana",
It can be replaced with "alphabet".

Note that such replacement with the designated character type is performed as follows.
The present invention is also applicable to the second to fourth embodiments. That is, in each embodiment, if a conversion candidate is not obtained even when the input reading character string is replaced with Pinyin or Double Pinyin, the input reading character string is changed to the specified character type according to the character type specified as the final character. What is necessary is just to add the process which replaces with.

The method described in each of the embodiments described above can be executed by a computer as a program such as a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM,
It is also possible to write the data on a recording medium such as a DVD or a semiconductor memory and apply it to various devices, or to transmit it via a communication medium and apply it to various devices. A computer that realizes the present apparatus reads the program recorded on the recording medium, and executes the above-described processing by controlling the operation of the program.

[0137]

As described above, according to the present invention, in the Chinese input conversion processing device having the input mode of the pinyin input mode and the double pinyin input mode, the conversion target in the state where the double pinyin input mode is set Was replaced with Pinyin, and if the replaced readout string did not conform to the Pinyin rules, it was assumed to have been entered by Pinyin and returned to the state at the time of input and converted to Chinese. A desired conversion candidate can be obtained by using pinyin and double pinyin without switching modes.

Further, in a Chinese input conversion processing device having an input mode of a pinyin input mode and a double pinyin input mode, when the pinyin input mode is set, a Chinese conversion is performed based on a read character string to be converted. When the conversion candidate is not obtained, it is assumed that the input is performed in double pinyin, the read character string is replaced with pinyin, and the conversion process is performed again based on the replaced read character string. Therefore, a desired conversion candidate can be obtained by using both pinyin and double pinyin without switching the input mode.

If the reading input in the double pinyin input mode does not conform to the pinyin rules, and a conversion candidate is not obtained even if the dictionary is referred to as being input in pinyin, for example, the front side is pinned in. In the double pinyin input mode, conversion candidates can be obtained even in a double-pinyin input mode, even if the readout character string includes pinyin on the front side.

Further, when the reading input in the double pinyin input mode does not conform to the pinyin rule, and a conversion candidate is not obtained even if the dictionary is referred to as being input in pinyin, for example, the front side is doubled. By dividing and converting the reading with the pinyin and the back side as the pinyin, conversion candidates can be obtained even in the double-pinyin input mode even if the reading character string includes the pinyin on the front side.

In the case where the position of the double pinyin and the pinyin determined by the system as described above are incorrect, the user can arbitrarily correct the position to obtain a conversion candidate according to the corrected position. Can be obtained.

When a conversion candidate is not obtained even when the input character string is replaced with Pinyin or Double Pinyin, the input mode is switched by finally replacing the character string with Hiragana. Instead, you can enter Hiragana.

Also, by specifying the type of the final output character in advance, if a conversion candidate is not obtained even if the input reading character string is replaced with Pinyin or Double Pinyin, the reading character string is replaced with a new one. By finally converting to the character type specified above, without switching the input mode,
A desired character type can be input.
