Abstract

PROBLEM TO BE SOLVED: To confirm a part which can be interpreted as pinyin and other parts in the case of pinyin input. SOLUTION: When a character string is inputted from an input part 21, an input control processing part 22 decides whether or not the input character string is a pinyin through a pinyin substitution control part 23. Then the pinyin substitution control part 23 checks the input character string by referring to a pinyin rule table 23a. Then an indication is sent to an editor 27 so that the character string is displayed in a 1st display style when pinyin and in a 2nd display style when not.

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 Chinese input suitable for use in performing a conversion process by pinyin input. The present invention relates to a conversion processing apparatus, a Chinese input conversion processing method used in the Chinese input conversion processing apparatus, and a recording medium that stores 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. The following description is made on the assumption that a character input method based on pinyin is used.

[0006] In a device for converting Pinyin input by alphabet into Chinese, the current problem is how quickly.
Efficient and accurate conversion of Pinyin to Chinese Kanji.

[0007] As described above, Pinyin input is an input method in which Chinese kanji readings are represented by alphabets. Similar to Japanese Roman alphabet readings, combinations of alphabets for expressing Chinese kanji readings are prescribed. Other combinations are not established as pinyin.

[0008] In addition, when inputting Japanese Roman characters, the characters are converted to Hiragana and displayed at the time of input, and when an input that does not hold as Roman characters is performed, Roman characters (alphabet) are displayed as they are. Therefore, the user can immediately judge whether or not the character string input in Roman characters at the time of input is correct.

However, in Chinese Pinyin input, there is no equivalent to Japanese Hiragana, so there is no change at the time of inputting the alphabet, and unless it is converted to Chinese Kanji by pressing the conversion key, It is not possible to determine whether the correct alphabet has been entered as Pinyin.

[0010]

As described above, conventionally, with pinyin input, it has not been possible to determine whether or not the correct alphabet has been input as pinyin until the conversion result is viewed. For this reason, there has been a very inconvenient problem such as carefully checking the character string at the time of pinyin input, or re-inputting and converting the error portion after conversion.

Further, when a character string that does not hold as pinyin is input, it is not possible to perform switching so that subsequent input character strings are pinyin or remain in the alphabet at the time of input. For this reason, it is inconvenient when, for example, it is desired to input alphabets intentionally or when pinyin input is to be performed with mixed alphabets.

The present invention has been made in view of the above points, and when performing pinyin input, a portion that can be interpreted as pinyin and a portion that cannot be interpreted as pinyin can be confirmed at the time of input. To provide a Chinese input conversion processing device, a Chinese input conversion processing method, and a recording medium on which a Chinese input conversion processing program for realizing smooth pinyin input is provided. Aim.

[0013]

According to a first aspect of the present invention, there is provided a Chinese character input conversion processing device, comprising: an input unit for inputting a character string; and whether or not the character string input by the input unit is pinyin. Pinyin determination means for determining whether
Input character string storage means for adding attribute information corresponding to the determination result of the pinyin determination means to the input character string and storing the input character string; and storing the input character string stored in the input character string storage means in the attribute information. And distinguish them based on
Display means for displaying, in a first display mode, a character string that is established as Pinyin, and displaying a character string that is not established as Pinyin in a second display mode.

According to such a configuration, when the input character string is established as pinyin, it is displayed in the first display mode, and when it is not established as pinyin, it is displayed in the second display mode. Therefore, at the time of input, it can be determined whether or not a character string is established as Pinyin, and a portion not established as Pinyin can be corrected before conversion.

According to a second aspect of the present invention, there is provided a Chinese character input conversion processing device for inputting a character string and determining whether or not the character string input by the input means is valid as a pinyin. Pinyin determination means, input character string storage means for adding attribute information according to the determination result of the pinyin determination means to the input character string and storing the same, and a display mode for setting a first or second display mode Setting means for displaying the input character string stored in the input character string storage means based on the attribute information, wherein the first display mode is set by the display mode setting means. Displays a character string that is established as Pinyin in a first display mode, displays a character string that is not established as Pinyin in a second display mode, and sets the second display mode. If that is characterized by comprising a display means for displaying the character string input to the subsequent string not true as pinyin in the second display mode without interpreting as Pinyin.

According to such a configuration, the first or second display mode can be arbitrarily selected when displaying the input character string. In the second display mode, character strings subsequent to a character string that does not hold as pinyin are displayed in the second display mode without being interpreted as pinyin. Therefore, for example, it is convenient when the alphabet is intentionally input, or when pinyin and the alphabet are mixed and input.

In the first display mode, a character string subsequent to a character string that is not satisfied as pinyin is interpreted as pinyin, and is displayed in the first display mode when it is satisfied as pinyin, and is displayed in the second display mode when it is not satisfied as pinyin. It is displayed in a display form. Therefore, when performing pinyin input, it is possible to determine whether or not a character string is established as pinyin at the time of input, and it is possible to correct a portion that is not established as pinyin before conversion.

According to a third aspect of the present invention, in the first or second aspect, there is provided a display mode setting means for setting a non-differential display mode, and the display means is provided with the non-differential display by the display mode setting means. When the mode is set, all of the input character strings are displayed in the same display form.

According to such a configuration, by selecting the non-distinguishable display mode, all of the input character strings are displayed in the same display form. It is convenient.

According to a fourth aspect of the present invention, there is provided a Chinese input conversion processing apparatus comprising: an input unit for inputting a character string; and a pinyin determination for determining whether or not the character string input by the input unit is valid as a pinyin. Means, input character string storage means for adding attribute information corresponding to the determination result of the pinyin determination means to the input character string and storing the same, and conversion mode setting means for setting the first or second conversion mode When,
Converting the input character string stored in the input character string storage means into Chinese kanji based on the attribute information;
When the first conversion mode is set by the conversion mode setting means, the character string that is established as Pinyin is converted into Chinese kanji and output, and the character string that is not established as Pinyin is output as it is. In the case where the second conversion mode is set, a character string input after a character string that is not satisfied as pinyin is not interpreted as pinyin, but is output as it is without conversion.

According to such a configuration, when converting the input character string, the first or second conversion mode can be arbitrarily selected. In the second conversion mode, character strings input after a character string that does not hold as pinyin are not interpreted as pinyin, and are displayed as they are during conversion. Therefore, for example, when an alphabet is intentionally input or when pinyin input is to be performed with a mixture of alphabets, a word composed of, for example, an alphabet can be obtained without a mode switching operation.

In the first conversion mode, a character string input after a character string that is not satisfied as Pinyin is interpreted as Pinyin. If the character string is satisfied as Pinyin, it is converted to Chinese at the time of conversion and must not be realized as Pinyin. If
It is displayed as it is. Therefore, when inputting Pinyin, a conversion candidate corresponding to a character string correct as Pinyin can be obtained.

In addition, a homophone selection process, a learning process, and the like are also performed. The processing performed by the conversion control unit 24 can be included in the input control processing unit 22 or the editor 27.

The Chinese conversion processing unit 25 performs syntax analysis and the like, and converts the reading into Chinese kanji with reference to the Chinese dictionary 26. In the Chinese dictionary 26, Chinese kanji readings and corresponding headings are registered in Pinyin notation (see FIG. 3). This Chinese dictionary 26 is stored in the external storage device 1
5 is stored.

The editor 27 stores and edits a character string obtained from the input control processing unit 22 or the conversion control unit 24, and gives a display instruction. The output unit 28 performs output processing such as displaying the character string sent from the editor 27 on the display device 14.

FIG. 3 shows the structure of the Chinese dictionary 26. In the Chinese dictionary 26, information necessary for the Pinyin kanji conversion process, such as Chinese Pinyin reading, headline, part of speech, etc., 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 27, all readings are registered in pinyin.

Here, 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 final, but there are some combinations that are not possible 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 23a of FIG. 2, the combination of the initial and final used as the Chinese standard tone 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.

Next, the processing operation according to the first embodiment of the present invention will be described. Conventionally, since there is no equivalent of Japanese Hiragana in pinyin input, it is not possible to easily identify a portion that does not hold as pinyin until a conversion result is output. Therefore, in the first embodiment, when a character string is input, a portion that is established as pinyin is displayed in the first display mode, and a portion that is not established as pinyin is displayed in the second display mode. It is like that.

FIG. 7 is a flowchart for explaining the processing operation according to the first embodiment of the present invention. First,
As an initial setting, the pinyin interpretation flag of the flag buffer 22b provided in the input control processing unit 22 is turned on (step A11). The Pinyin interpretation flag indicates whether or not to interpret the input character string as Pinyin, and indicates that it is interpreted as Pinyin when ON.
Indicates that it is not interpreted as pinyin when OFF.

A reading character string (alphabet) or a conversion instruction to be converted is input by a key through the input unit 21 (step A12). The input control processing unit 22 determines the input key. If the input key is a character input key (No in step A13), the input characters are sequentially stored in the reading character string buffer 22a (step A14). At this time, the input control processing unit 22 sets the character status information added as attribute information to the input character to an “unknown” state (step A15). This character status information has three states: "unknown", "established", and "not established".

Here, the input control processing section 22 sends the input characters stored in the read character string buffer 22a to the pinyin replacement control section 23, and performs a process of determining whether or not the input character is established as pinyin (step A16). A17). The Pinyin replacement control unit 23 refers to the Pinyin rule table 23a to determine whether the input character is valid as Pinyin, and returns the determination result to the input control processing unit 22.
In the pinyin rule table 23a, as shown in FIG.
A combination of the initial and the final used as a Chinese standard tone is stored in advance as a Pinyin rule. It can be determined that a character string that is not in this pinyin rule does not hold as pinyin.

In this case, when one character is input,
Since it is not yet determined whether or not it is established as pinyin (No in step A17), the input control processing unit 22 keeps the character status information in the "unknown" state (step A19) and turns on the pinyin interpretation flag. State (step A21), and the input character is temporarily displayed in the display color A.
Instructs the editor 27 to display in step A.
22). Thereby, the input character is displayed on the screen in the display color A (for example, blue).

If it is determined that the character string is formed as a pinyin by inputting a number of characters (Yes in step A17), the input control processing unit 22 changes the currently input character to the previously input character. To set the status information of the character in the "unknown" state to the "established" state (step A18). After turning on the Pinyin interpretation flag (step A21), the input control processing unit 22 instructs the editor 27 to display the input character and the previous input character in the display color A (step A22). As a result, the character string established as pinyin is displayed in color A
(For example, blue) on the screen.

On the other hand, if it is determined that the character string is not established as a pinyin by inputting a number of characters (Yes in step A16), the input control processing unit 22 changes the character input from the currently input character to the character input earlier. To set the status information of the character in the "unknown" state to the "unsatisfied" state (step A20). Then, the input control processing unit 22 turns off the pinyin interpretation flag (step A2).
3) Instruct the editor 27 to display the input character and the previous input character in the display color B (step A24). As a result, a character string that does not hold as pinyin is displayed on the screen in the display color B (for example, red).

In step A13, when a Chinese character conversion is instructed by inputting a conversion key or a single kanji key, the input control processing unit 22 converts the character string stored in the reading character string buffer 22a into a conversion character string. Hand over to section 24. The conversion control unit 24 performs a Chinese conversion process on a character string that is established as Pinyin based on the status information of each character (step A25). Specifically, a process of searching for a heading that reads the character string from the Chinese dictionary 26 through the Chinese conversion processing unit 25 and outputting this as a conversion candidate is performed.

As described above, when the input character string is established as pinyin, it is displayed in display color A, and when it is not established as pinyin, it is displayed in display color B.
The user can determine at the time of input whether or not the character string is established as a pinyin, and a portion that is not established as a pinyin (that is, a portion displayed in the display color B).
Can be corrected before conversion.

In the above-described embodiment, the pinyin determination processing is performed for each character to perform the distinction display. However, when a character string that can be determined as pinyin is obtained, the pinyin determination processing is performed to execute the character string. Can also be distinguished.

Further, in the above-described embodiment, the distinction display is performed according to the color. However, the distinction display may be performed using another display form, for example, by adding an underline to a character string that does not hold as pinyin. good.

(Second Embodiment) In the second embodiment,
There are a first display mode and a second display mode as distinctive display modes, and a character string subsequent to a character string that does not hold as pinyin in the second display mode is not interpreted as pinyin.
Is interpreted as a pinyin, and a character string subsequent to a character string that does not hold as pinyin in the first display mode is displayed as pinyin. In this case, it is displayed in the second display mode.

FIG. 8 is a flow chart for explaining the processing operation according to the second embodiment of the present invention. In addition,
The processing in steps B11 to B15 and steps B18 to B27 is performed in steps A11 to A15 and step A1 in FIG.
This is the same as the processing from 6 to A25.

That is, first, as an initial setting, the pinyin interpretation flag of the flag buffer 22b provided in the input control processing unit 22 is turned on (step B11).
The Pinyin interpretation flag indicates whether or not to interpret the input character string as Pinyin. When it is ON, it indicates that it is interpreted as Pinyin, and when it is OFF, it indicates that it is not interpreted as Pinyin.

A reading character string (alphabet) or a conversion instruction to be converted is input by a key input from the input unit 21 (step B12). The input control processing unit 22 determines the input key, and if it is a character input key (No in step B13), the input characters are sequentially stored in the reading character string buffer 22a (step B14). At this time, the input control processing unit 22 sets the character status information added as attribute information to the input character to an “unknown” state (step B15). This character status information has three states: "unknown", "established", and "not established".

Here, in the second embodiment, the process branches depending on whether the first display mode is set or when the second display mode is set. In the second display mode, a character string subsequent to a character string that does not hold as pinyin is displayed in the second display mode without being interpreted as pinyin.
In the first display mode, a character string subsequent to a character string that is not satisfied as pinyin is interpreted as pinyin, and is displayed in the first display form when it is realized as pinyin, and is displayed in the second display form when it is not satisfied as pinyin. indicate. These display modes can be arbitrarily designated by, for example, an environment setting operation at the time of document creation, and the type of the designated mode is determined by the mode buffer 22 of the input control processing unit 22.
c.

When the first display mode is set (Yes in step B16), the same processing as in the first embodiment is performed. That is, the input control processing unit 22
The input characters stored in the read character string buffer 22a are sent to the Pinyin replacement control unit 23, and a determination process is performed to determine whether or not Pinyin is established (steps B18 and B19).
In the Pinyin replacement control unit 23, the Pinyin rule table 2
3a, it is determined whether or not the input character is established as a pinyin, and the determination result is input to the input control processing unit 22.
To return. As shown in FIG. 6, the combination of the initial and final used as the Chinese standard tone is stored in the pinyin rule table 23a as the pinyin rule in advance. It can be determined that a character string that is not in this pinyin rule does not hold as pinyin.

In this case, when one character is input,
Since it is not yet determined whether or not it is established as a pinyin (No in step B19), the input control processing unit 22 keeps the character status information in the “unknown” state (step B21) and turns on the pinyin interpretation flag. State (step B23), and the input character is temporarily displayed in the display color A.
Instruct the editor 27 to display (Step B)
24). Thereby, the input character is displayed on the screen in the display color A (for example, blue).

If it is determined that the character string is formed as a pinyin by inputting a number of characters (Yes in step B19), the input control processing unit 22 determines whether the currently input character is a previously input character. To set the status information of the character in the "unknown" state to the "established" state (step B20). After turning on the Pinyin interpretation flag (step B23), the input control processing unit 22 instructs the editor 27 to display the input character and the previous input character in the display color A (step B24). As a result, the character string established as pinyin is displayed in color A
(For example, blue) on the screen.

On the other hand, if it is determined that the character string is not established as a pinyin by inputting some characters (Yes in step B18), the input control processing unit 22 determines that the currently input character is To set the status information of the character in the "unknown" state to the "unsatisfied" state (step B22). Then, the input control processing unit 22 turns off the pinyin interpretation flag (step B2).
5) Instruct the editor 27 to display the input character and the previous input character in the display color B (step B26). As a result, a character string that does not hold as pinyin is displayed on the screen in the display color B (for example, red).

In step B16, the second
If the display mode is set, the input control processing unit 22 checks the Pinyin interpretation flag in the flag buffer 22b (step B17). If the pinyin interpretation flag is ON (No in step B17), the input control processing unit 22 interprets the character string input thereafter as pinyin, and displays the first or second display according to the interpretation result. It is displayed in a form (steps B18 to B26).

On the other hand, if the pinyin interpretation flag is in the OFF state (Yes in step B17), the input control processing unit 2
No. 2 does not interpret a character string inputted thereafter as pinyin but displays it in the second display mode (steps B22 to B22).
B26). That is, once a character string that is not interpreted as Pinyin is input, all subsequent input character strings are displayed in the second display format without being subject to Pinyin.

In the step B13, when the conversion is instructed by inputting the conversion key or the single kanji key, the input control processing unit 22 converts the character string stored in the read character string buffer 22a into the conversion character string. Hand over to section 24. The conversion control unit 24 performs a Chinese conversion process on a character string that is established as Pinyin based on the status information of each character (step B27). Specifically, a process of searching for a heading that reads the character string from the Chinese dictionary 26 through the Chinese conversion processing unit 25 and outputting this as a conversion candidate is performed.

As described above, the first display mode and the second display mode can be arbitrarily selected. In this case, in the second display mode, a character string subsequent to a character string that does not hold as pinyin is displayed in the second display format without being interpreted as pinyin. This is convenient when inputting alphabets and other characters together.

In the first display mode, a character string subsequent to a character string that is not satisfied as pinyin is interpreted as pinyin, and is displayed in the first display mode when it is satisfied as pinyin. 2, the user can determine whether or not a character string is established as Pinyin at the time of input, as in the first embodiment. The portion that does not hold (that is, the portion displayed in the display color B) can be corrected before conversion.

(Third Embodiment) In the third embodiment,
It has a distinctive display mode and a non-distinguishable display mode, and displays all input character strings in the same display form regardless of whether or not it is established as a pinyin in the non-distinctive display mode. As in the first embodiment, when a character string is input, a portion that is established as pinyin is displayed in the first display mode, and a portion that is not established as pinyin is displayed in the second display mode. It is like that.

FIG. 9 is a flowchart for explaining a processing operation according to the third embodiment of the present invention. In addition,
The processing in steps C11 to C14 and steps C16 to C26 is performed in steps A11 to A14 and step A1 in FIG.
This is the same as the processing from 6 to A26.

That is, first, as an initial setting, the Pinyin interpretation flag of the flag buffer 22b provided in the input control processing unit 22 is turned on (step C11).
The Pinyin interpretation flag indicates whether or not to interpret the input character string as Pinyin. When it is ON, it indicates that it is interpreted as Pinyin, and when it is OFF, it indicates that it is not interpreted as Pinyin.

A reading character string (alphabet) or a conversion instruction to be converted is input through the input unit 21 (step C12). The input control processing unit 22 determines the input key. If the input key is a character input key (No in step C13), the input characters are sequentially stored in the read character string buffer 22a (step C14).

Here, in the third embodiment, the processing branches depending on whether the distinctive display mode is set or not and the case where the non-distinct display mode is set. In the non-differentiated display mode, all input character strings are displayed in the same display format regardless of whether or not they are established as pinyin. In the distinctive display mode, character strings are input in the same manner as in the first embodiment. At a point in time, a portion that has been established as pinyin is displayed in the first display mode, and a portion that has not been established as pinyin is displayed in the second display mode. These display modes can be arbitrarily specified by, for example, an environment setting operation when a document is created, and the type of the specified mode is determined by the mode buffer 2 of the input control processing unit 22.
2c.

When the non-discriminating display mode is set (Yes in step C15), the input control processing unit 22 displays all the input character strings in the same display form (here, the first character string).
To the editor 27). Thereby, the input character is displayed on the screen in the display color A (for example, blue).

When the distinctive display mode is set (No in step C15), the same processing as in the first embodiment is performed. That is, the input control processing unit 22 sets the character status information added as attribute information to the input character to an “unknown” state (step C16). This character status information has three states: "unknown", "established", and "not established".

Here, the input control processing unit 22 sends the input characters stored in the read character string buffer 22a to the pinyin replacement control unit 23, and performs a process of determining whether or not the input character is established as pinyin (step C17, C18). The Pinyin replacement control unit 23 refers to the Pinyin rule table 23a to determine whether the input character is valid as Pinyin, and returns the determination result to the input control processing unit 22.
In the pinyin rule table 23a, as shown in FIG.
A combination of the initial and the final used as a Chinese standard tone is stored in advance as a Pinyin rule. It can be determined that a character string that is not in this pinyin rule does not hold as pinyin.

In this case, when one character is input,
Since it is not yet determined whether or not the condition is established as Pinyin (No in Step C18), the input control processing unit 22 keeps the character status information in the “unknown” state (Step C20) and turns on the Pinyin interpretation flag. State (step C22), and the input character is temporarily displayed in the display color A.
Instructs the editor 27 to display the image (step C).
23). Thereby, the input character is displayed on the screen in the display color A (for example, blue).

If it is determined that the character string is formed as a pinyin by inputting a number of characters (Yes in step C18), the input control processing unit 22 changes the currently input character to the previously input character. To set the status information of the character in the "unknown" state to the "established" state (step C19). After turning on the Pinyin interpretation flag (step C22), the input control processing unit 22 instructs the editor 27 to display the input character and the previous input character in the display color A (step C23). As a result, the character string established as pinyin is displayed in color A
(For example, blue) on the screen.

On the other hand, if it is determined that the character string is not valid as a pinyin by inputting some characters (Yes in step C17), the input control processing unit 22 determines the character input from the currently input character to the character input before it. To set the status information of the character in the "unknown" state to the "unsatisfied" state (step C21). Then, the input control processing unit 22 turns off the Pinyin interpretation flag (step C2).
4) Instruct the editor 27 to display the input character and the previous input character in the display color B (step C25). As a result, a character string that does not hold as pinyin is displayed on the screen in the display color B (for example, red).

In the above step C13, if a Chinese conversion is instructed by inputting a conversion key or a single kanji key, the input control processing unit 22 converts the character string stored in the reading character string buffer 22a into a conversion character string. Hand over to section 24. The conversion control unit 24 performs a Chinese conversion process on the character string that is established as Pinyin based on the status information of each character (step C26). Specifically, a process of searching for a heading that reads the character string from the Chinese dictionary 26 through the Chinese conversion processing unit 25 and outputting this as a conversion candidate is performed.

As described above, the distinction display mode and the non-discrimination display mode can be arbitrarily selected. In this case, in the non-distinguishable display mode, all the input character strings are displayed in the same display form, which is convenient when, for example, normal display is desired at the time of pinyin input.

Further, in the distinction display mode, a character string that is established as a pinyin and a character string that is not established are displayed in a distinctive manner. Can be determined whether Pinyin is established as Pinyin, and a portion that is not established as Pinyin (that is, a portion displayed in the display color B) can be corrected before conversion.

The display processing having such a distinctive display mode and a non-differential display mode is performed in the second embodiment (display processing having a first display mode and a second display mode).
Is also applicable. In this case, step B in FIG.
After step 14, the determination processing in step C15 may be added to perform the display processing of the display color A in step B22 in the non-discriminating display mode.

(Fourth Embodiment) Conventionally, when a character string that does not hold as pinyin is input, it is not possible to switch between subsequent input character strings as pinyin or as an alphabet. Therefore, it is inconvenient when, for example, it is desired to input alphabets intentionally or when pinyin input is to be performed with alphabets mixed.

Therefore, in the fourth embodiment, it is possible to specify whether or not to interpret and convert as pinyin by a mode. Specifically, the first conversion mode and the second conversion mode
And a character string that does not hold as pinyin in the second conversion mode is output as it is without being interpreted as pinyin, and a character string that does not hold as pinyin in the second conversion mode The subsequent character string is interpreted as Pinyin, and if it is established as Pinyin, it is converted into Chinese and its conversion candidate is output. If it is not established as Pinyin, it is output as it is.

FIGS. 10 and 11 are flow charts for explaining the processing operation according to the fourth embodiment of the present invention. Steps D11 to D15 and step D1
8 to D26 are performed in steps A11 to A1 in FIG.
5. The processing is the same as the processing in steps A16 to A24.

That is, first, as an initial setting, the Pinyin interpretation flag of the flag buffer 22b provided in the input control processing section 22 is turned on (step D11).
The Pinyin interpretation flag indicates whether or not to interpret the input character string as Pinyin. When it is ON, it indicates that it is interpreted as Pinyin, and when it is OFF, it indicates that it is not interpreted as Pinyin.

A reading character string (alphabet) or a conversion instruction to be converted is input through the input unit 21 (step D12). The input control processing unit 22 determines the input key. If the input key is a character input key (No in step D13), the input characters are sequentially stored in the reading character string buffer 22a (step D14). At this time, the input control processing unit 22 sets the character status information added as attribute information to the input character to an “unknown” state (step D15). This character status information has three states: "unknown", "established", and "not established".

Here, in the fourth embodiment, the process branches depending on whether the first conversion mode is set or when the second conversion mode is set. In the second conversion mode, a character string subsequent to a character string that does not hold true as Pinyin is output without being interpreted as Pinyin. In the second conversion mode, a character string subsequent to a character string that is not satisfied as Pinyin is interpreted as Pinyin, and if it is realized as Pinyin, it is converted into Chinese and its conversion candidate is output. . These conversion modes can be arbitrarily designated by, for example, an environment setting operation at the time of document creation, and the type of the designated mode is held in the mode buffer 22c of the input control processing unit 22.

If the first conversion mode is set (Yes in step D16), the same input processing as in the first embodiment is performed, and then the processing shifts to the conversion processing.

That is, the input control processing unit 22 sends the input characters stored in the read character string buffer 22a to the pinyin replacement control unit 23, and performs a process of determining whether the input character is established as pinyin (steps D18 and D19). ). The Pinyin replacement control unit 23 refers to the Pinyin rule table 23a to determine whether the input character is valid as Pinyin, and returns the determination result to the input control processing unit 22. As shown in FIG. 6, the combination of the initial and final used as the Chinese standard tone is stored in the pinyin rule table 23a as the pinyin rule in advance. It can be determined that a character string that is not in this pinyin rule does not hold as pinyin.

In this case, when one character is input,
Since it is not yet determined whether or not the condition is established as Pinyin (No in Step D19), the input control processing unit 22 keeps the character status information in the “unknown” state (Step D21) and turns on the Pinyin interpretation flag. State (step D23), and the input character is temporarily displayed in the display color A.
Instructs the editor 27 to display in step D.
24). Thereby, the input character is displayed on the screen in the display color A (for example, blue).

If it is determined that the character string is formed as a pinyin by inputting a number of characters (Yes in step D19), the input control processing unit 22 determines whether the currently input character is a character input earlier. To set the status information of the character in the "unknown" state to the "established" state (step D20). Then, after turning on the Pinyin interpretation flag (step D23), the input control processing unit 22 instructs the editor 27 to display the input character and the previous input character in the display color A (step D24). As a result, the character string established as pinyin is displayed in color A
(For example, blue) on the screen.

On the other hand, if it is determined that the character string is not established as a pinyin by inputting some characters (Yes in step D18), the input control processing unit 22 determines that the currently input character is To set the status information of the character in the "unknown" state to the "unsatisfied" state (step D22). Then, the input control processing unit 22 turns off the Pinyin interpretation flag (step D2).
5) Instruct the editor 27 to display the input character and the previous input character in the display color B (step D26). As a result, a character string that does not hold as pinyin is displayed on the screen in the display color B (for example, red).

In step D16, the second
If the conversion mode is set, the input control processing unit 22 checks the Pinyin interpretation flag in the flag buffer 22b (step D17). If the pinyin interpretation flag is ON (No in step D17), the input control processing unit 22 interprets the character string input thereafter as pinyin, and displays the first or second display according to the interpretation result. It is displayed in a form (steps D18 to D26).

On the other hand, if the Pinyin interpretation flag is in the OFF state (Yes in step D17), the input control processing unit 2
No. 2 does not interpret a character string inputted thereafter as pinyin but displays it in the second display form (steps D22 to D22).
D26). That is, once a character string that is not interpreted as Pinyin is input, all subsequent input character strings are displayed in the second display format without being subject to Pinyin.

Next, conversion processing after such input processing will be described. In step D13, when the Chinese conversion is instructed by inputting the conversion key or the single kanji key, the input control processing unit 22 converts the character string stored in the reading character string buffer 22a together with the status information into the conversion control unit 24. Pass to. The conversion control unit 24 checks the status information of each character in order from the first character (steps D27 and D28).

As a result, the character status information becomes "established".
If it is in the state (Ye in step D29)
s), the conversion control unit 24 extracts the character string in the “established” state including the character as one conversion unit, and sends it to the Chinese conversion processing unit 25 (step D30). Chinese conversion processing unit 2
In 5, the Chinese dictionary 26 is searched based on the character string, and a heading that reads the character string is extracted from the Chinese dictionary 26 and returned to the conversion control unit 24 (step D30).

The conversion control unit 24 includes a Chinese conversion processing unit 25
The editor 27 is instructed to output the headline acquired from the above as a conversion candidate (step D31). As a result, Chinese characters are displayed on the screen in place of the character string (alphabet) input as a reading.

On the other hand, when the character status information is in the "unsatisfied" or "unknown" state (step D2).
9: No), the conversion control unit 24 instructs the editor 27 to output the character as it is (step D3).
2). As a result, the character string (alphabet) input as a reading is displayed on the screen as it is.

As described above, when the conversion is instructed, the input character string is converted into Chinese and output based on the status information added to the character string to be converted, or is directly output. Is output.

In this case, when the second conversion mode is set, character strings input after a character string that is not satisfied as pinyin are not interpreted as pinyin, and all of their status information is in a “not satisfied” state. ing. Therefore, at the time of conversion, it is displayed as it is (alphabet). Therefore, for example, when the alphabet is intentionally input or when the pinyin input is to be performed with the alphabet mixed, a word composed of the alphabet can be obtained without the mode switching operation.

On the other hand, when the first conversion mode is set, character strings input after a character string that does not hold as pinyin are interpreted as pinyin, and status information is changed according to the interpretation result. I have. Therefore, if it is established as Pinyin, it is converted into Chinese at the time of conversion, and if it is not established as Pinyin, it is displayed as it is (alphabet). Therefore, when inputting Pinyin, a conversion candidate corresponding to a character string correct as Pinyin can be obtained.

Here, the first and second display modes and the first and second conversion modes will be described with reference to specific examples. FIG. 12 shows a specific example.

For example, as shown in FIG.
nzhuangruangjiandecd-romqu
It is assumed that a character string such as “dongqi” has been pinyin input. In this character string, the “cd-rom” part is a character string that does not hold as pinyin.

Here, when the second display mode (the same applies to the second conversion mode) is set at the time of input, the character string “qu donq qi” input after the character string that does not hold as pinyin Is not interpreted as Pinyin. Therefore, as shown in FIG.
The “cd-rom quong qi” part is the second
Is displayed in a display mode (for example, red), and the other part “an
“zhuang ran jian de” will be displayed in the first display mode (for example, blue).

On the other hand, when the first display mode (the same is true for the first conversion mode) is set, the character string “qu do
"ngqi" is interpreted as pinyin. in this case,
“Qu dong qi” is a character string that is established as Pinyin. Therefore, as shown in FIG.
Only the portion of “cd-rom” is displayed in the second display mode (for example, red), and the other portion “an zhuang r” is displayed.
"uan jian de" and "qu donqqi" will be displayed in the first display mode (for example, blue).

When the second conversion mode is set at the time of conversion, character strings input after a character string that does not hold as pinyin are not interpreted as pinyin as in the case of display. Therefore, as shown in FIG. 12 (d), "an zhang ruan jia
The part "n" is converted to a Chinese kanji such as "Aso soft", but the part "cd-rom qong qi" is output as it is.

On the other hand, when the first conversion mode is set, as in the case of display, character strings input after a character string that does not hold as pinyin are interpreted as pinyin. In this case, "qu dong qi" is a character string that is established as Pinyin, and can be converted into Chinese kanji such as "driver". Therefore, FIG.
As shown in (e), only the “cd-rom” portion is output as it is.

In the examples shown in FIGS. 12B to 12E, the input character strings are displayed as being separated from each other. However, this is because the conversion unit is clearly shown, and in practice As shown in FIG. 12 (a), the input character string is displayed without delimiters (same as Japanese Roman character input).

FIG. 13 shows another specific example. For example, FIG.
As shown in FIG. 3 (a), “xitonbanbenw
It is assumed that a character string such as “windows95yishang” has been pinyin-inputted. In this string, "win
The part “dos95” is a character string that does not hold as pinyin.

Here, when the second display mode (the same applies to the second conversion mode) is set at the time of input, the character string "yishhang" input after the character string that does not hold as pinyin Not interpreted as Pinyin. Therefore, as shown in FIG.
The part “dos95 yishang” is displayed in the second display form (for example, red), and the other part “xitong”
“banben” will be displayed in the first display format (for example, blue).

On the other hand, when the first display mode (the same is true for the first conversion mode) is set, the character string “yishha” input after the character string that does not hold as pinyin
"ng" is interpreted as pinyin. In this case, "yi
"shang" is a character string that is established as pinyin.
Therefore, as shown in FIG.
ws95 ”only in the second display mode (for example, red)
And the other part "xitong banben"
And "yishhang" are the first display format (for example, blue)
Will be displayed.

When the second conversion mode is set at the time of conversion, as in the case of display, character strings input after a character string that does not hold as pinyin are not interpreted as pinyin. Therefore, as shown in FIG. 13 (d), the part of “xitongbanben” is converted into Chinese kanji such as “sequel edition book”,
The part of “windows95yishang” is output as it is.

On the other hand, when the first conversion mode is set, the character strings input after the character string that does not hold as pinyin are interpreted as pinyin, as in the case of display. In this case, "yishhang" is a character string that is established as a pinyin, and can be converted into Chinese characters such as "or more." Therefore, as shown in FIG. 13E, only the "windows95" portion is output as it is.

In the examples shown in FIGS. 13B to 13E, the input character strings are displayed as being separated from each other. However, this is because the conversion unit is clearly indicated, and in practice, As shown in FIG. 13 (a), the input character string is displayed without delimiters (same as Japanese Roman character input).

Further, the method described in each of the above-described embodiments may be a computer-executable 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.

[0116]

As described above, according to the present invention, it is determined whether or not an input character string is established as pinyin. If the input character string is established as pinyin, the character string is displayed in the first display mode. If the condition is not satisfied, the character string is displayed in the second display mode, so that it can be determined whether or not the character string is formed as pinyin at the time of input, and the portion not formed as pinyin is corrected before conversion. be able to.

In displaying an input character string, the first or second display mode can be set. In the second display mode, a character string subsequent to a character string that does not hold as pinyin is interpreted as pinyin without interpreting it as pinyin. Since the display is performed in the display mode 2, it is convenient when, for example, an alphabet is intentionally input, or when pinyin and the alphabet are mixed and input.

On the other hand, in the first display mode, a character string subsequent to a character string that is not satisfied as pinyin is interpreted as pinyin, and is displayed in the first display mode when it is satisfied as pinyin, and is displayed in a first display mode when it is not satisfied as pinyin. Since the display is performed in the display mode of 2, it is possible to determine whether or not a character string is established as a pinyin at the time of inputting, and to correct a portion that is not established as a pinyin before conversion. be able to.

Further, when the indistinguishable display mode is set, all the input character strings are displayed in the same display form, which is convenient when, for example, normal display is desired at the time of pinyin input.

When converting an input character string, the first or second conversion mode can be set. In the second conversion mode, a character string input after a character string that does not hold as pinyin is interpreted as pinyin. Instead, it is displayed as it is in the state of the alphabet at the time of conversion, so for example, when you want to enter the alphabet intentionally or when you want to input Pinyin with a mixture of alphabets, for example, a word consisting of alphabets without mode switching operation Can be obtained.

On the other hand, in the first conversion mode, a character string input after a character string that does not hold as Pinyin is interpreted as Pinyin. If not, it is displayed as it is. Therefore, when inputting pinyin, a conversion candidate corresponding to a character string correct as pinyin can be obtained.
