Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document preparation device having a kana-kanji conversion function.

[0002]

2. Description of the Related Art Conventionally, a kana-kanji conversion function for converting a hiragana character string input from a keyboard into a character string mixed with kanji has been provided as a standard function in a document creation device such as a Japanese word processor or personal computer. Has been. The kana-kanji conversion function basically uses a kana-kanji conversion dictionary to convert a kanji mixed character string containing kanji words corresponding to a hiragana character string.

The kana-kanji conversion function is available except when a single kanji word is obtained as a conversion candidate for an input character string.
A conversion candidate character string group including a plurality of homophones is output as a kana-kanji conversion result. As a specific example, for example, "Genkou"
For the input character string, "Original" which is a homonym,
A plurality of conversion candidates including “current”, “word”, etc. are output on the display screen of the display device.

Normally, the first candidate, for example, the "original" conversion candidate is displayed first, and each time the next candidate key on the keyboard is operated, the "current" and "word" conversion candidates are displayed. Displayed in order. The user selects a desired conversion candidate from the conversion candidates displayed in order and confirms it as the conversion result.

Further, the kana-kanji conversion function includes not only a character string containing kanji but also a so-called "single kanji conversion" function. This "single-kanji conversion" function normally displays a list of kanji corresponding to an input character string that is a phonetic reading by operating a specific key. "Single Kanji conversion" function is J
It is normal to display all homophones prepared in the dictionary without distinguishing IS first level, second level, common kanji, emergency kanji, etc.

[0006]

The conventional kana-kanji conversion function basically displays each conversion candidate in the same display form even when a plurality of homophones are included. Specifically, the first candidate is displayed in order or a list is displayed according to the operation of the next candidate key. In order to display that there are a plurality of conversion candidates, a display mode with blinking or an overline or underline is often used as the method of displaying in order.

However, the blink display is a display form that is difficult for the user to see. Further, the display form with overlines or underlines merely indicates that the same phoneme exists, and is not so different from the case where each conversion candidate is displayed in the same display form.

It is desirable for the user to have a display form in which a desired conversion candidate can be easily and surely selected when there are a plurality of conversion candidates including the same phoneme. For example, conversion candidates in a homophone may include conversion candidates in a specific field (historical term, scientific term, etc.) different from other standard fields. The standard field conversion candidates are those converted using a standard dictionary (body dictionary). On the other hand, the conversion candidates of the specific field are those converted by using the specific dictionary (extended dictionary) corresponding to each field. In such a case, if the conversion candidates of the specific field are displayed in a different display form from the others, it becomes easier for the user to select the conversion candidates of the specific field.

In the single-kanji conversion function, for example, J
It is very convenient to have different display modes according to the range of IS first level, second level, common kanji, emergency kanji, etc.
Furthermore, among the kanji of each conversion candidate, there are many similar kanji that have many strokes and are difficult to identify. If such a similar Chinese character is displayed, if the display form can be changed, it is possible to reduce the situation in which the user makes an incorrect selection.

It is an object of the present invention that, in the kana-kanji conversion function, when a conversion candidate including a plurality of homophones is displayed, a desired conversion candidate can be easily and surely selected by a display mode in which the display color is changed. It is to provide a document creation device to be realized.

[0011]

The present invention provides a kana-kanji conversion function for executing kana-kanji conversion processing of an input kana-character string and outputting a single or a plurality of conversion candidate character strings. It is an apparatus including display processing means for displaying a conversion candidate character string on a display screen in a display form in which a display color is changed based on a predetermined condition.

[0012]

According to the present invention, the display processing means displays a conversion candidate character string including a plurality of homophones as a first condition in a display color different from that of a single case. Second
As a condition, the display color is displayed in a different color for each dictionary to which the conversion candidate character string belongs. As a third condition, conversion candidate character strings that are similar to each other are displayed in different display colors. As the fourth condition, for example, different display colors are displayed so that the distinction between JIS first level and second level or common kanji and emergency kanji can be confirmed.

Judges the designated phonetic kana character string (kana-kanji conversion range) and sends the input kana-character string to the kana-kanji conversion control unit 1b.

The kana-kanji conversion control unit 1b uses the kana-kanji conversion dictionary 3 to execute kana-kanji conversion processing for converting an input kana character string into a kanji mixed character string or kanji character string. The conversion candidate display processing unit 1c performs a process of displaying the conversion candidates (the kanji mixed character string or the kanji character string that is the conversion result) obtained by the conversion process of the kana-kanji conversion control unit 1b on the display screen of the display device 8. Run. In the present invention, the conversion candidate display processing unit 1c executes display processing of a display form in which the display color is changed according to a predetermined condition, as described later.

The kana-kanji conversion dictionary 3 is a main body dictionary 3a,
It has a radical dictionary 3b and an extended dictionary 3c. The main body dictionary 3a is a standard dictionary in which the phonetic kana character strings of words and headwords are registered. The entry word is a kanji mixed character string or a kanji character string. The radical dictionary 3b registers the phonetic kana character strings of radical names and the kanji that belong to them. The extended dictionary 3c is a dictionary that can be attached to and detached from the main body of the apparatus, and is used, for example, for Kana-Kanji conversion of terms in specific fields such as Japanese history terms and scientific terms.

The similar Chinese character table 4 is a table registered in advance in the internal memory of the apparatus main body, and is composed of a Chinese character group whose forms are similar at the time of radical conversion. In the same embodiment, FIG.
As shown in FIG. 2, in the similar kanji table 4, two kinds of kanji 1 and kanji 2 that are similar to the reading kana character string of the radical name are registered.

The data storage unit 7 is a buffer memory for storing various data necessary for Kana-Kanji conversion processing, and has a conversion candidate table 7a, a color table 7b, and a similar word table 7c.

As shown in FIG. 2A, the conversion candidate table 7a is composed of headwords which are conversion candidates obtained by the kana-kanji conversion processing and information indicating the type of dictionary used. As shown in FIG. 2B, the color table 7b is a table for registering the type of dictionary and the designated color information. As shown in FIG. 2C, the similar word table 7c is a table for registering a word to be selected by the user and a similar word that the user easily mistakes in the phonetic alphabet character string.

Next, the operation of the embodiment will be described. (Operation of First Embodiment) The basic operation of the present invention will be described as a first embodiment with reference to the flow chart of FIG.

First, when a kana character string to be converted is input by a key input operation of the keyboard 2 and the conversion key 2a is operated, kana / kanji processing is started (step S1). The input control unit 1a sends the input character string (kana character string) in which the conversion range is set to the Kana-Kanji conversion control unit 1b (step S2).

The kana-kanji conversion control unit 1b uses the kana-kanji conversion dictionary 3 to execute kana-kanji conversion processing (step S3). The Kana-Kanji conversion control unit 1b uses the conversion key 2
In the normal conversion process by the operation of a, the main body dictionary 3a and the extended dictionary 3c are used. When the radical key 2c is operated, the kana-kanji conversion control unit 1b executes radical conversion processing.

The kana-kanji conversion control unit 1b outputs headwords including a plurality of homophones for the input character string as conversion candidates and registers them in the conversion candidate table 7a of the data storage unit 7 (step S4). At this time, the Kana-Kanji conversion control unit 1
As shown in FIG. 2A, b registers information indicating the type of dictionary used for each entry word.

In this embodiment, for example, for the input character string "genkou", the main dictionary 3a is searched for homophones such as "original" and "current", and the Japanese history term dictionary (extended) of the extended dictionary 3c. It is assumed that a homonym of “Genji” has been searched for.

The conversion candidate display processing unit 1c executes a display process for displaying each conversion candidate registered in the conversion candidate table 7a by the Kana-Kanji conversion control unit 1b on the display screen of the display device 8 (step S5). .

In this embodiment, the conversion candidate display processing section 1c
In the case of a single headword having no homophone, the kanji mixed character string or kanji character string that is the conversion candidate is displayed in black (monochrome) display color (NO in step S6, S8).

On the other hand, as shown in FIG. 2A, when there are a plurality of homophones, the conversion candidate display processing section 1c
Each conversion candidate character string is displayed in red color (YES in step S6, S7). In this case, the conversion candidate display processing unit 1c first displays the first candidate character string (for example, Genji) in red, and further, for example, “manuscript”, “current”, etc. in order according to the operation of the next candidate key. The homonyms of are displayed in red.

In the radical conversion process by operating the radical key 2c, the kana-kanji conversion control unit 1b uses the radical dictionary 3b to find the kanji candidate characters corresponding to the kana character string indicating the radical name. Register in the conversion candidate table 7a. Information indicating the radical dictionary 3b is set in the conversion candidate table 7a as the type of dictionary.

Similarly to the above, the conversion candidate display processing unit 1c displays in black if there is only a single Kanji candidate character. When there are a plurality of Kanji candidate characters belonging to the designated radical name, a list display in units of a predetermined number of words is displayed in red color.

According to the first embodiment as described above, when there are a plurality of conversion candidates (a plurality of Kanji candidates belonging to a homonym or a radical name), a display form whose display color is different from that of the single case is displayed. With this, the user can easily and surely recognize. Therefore, the desired Kana-Kanji conversion result can be easily confirmed on the display screen.

The flowchart of FIG. 5 shows a first modification of the first embodiment. In the first modified example, when a plurality of homophones exist, the number of homophones is, for example, 9
In the case of a large number of characters or more, each conversion candidate character string is displayed in color in red (YES in step S9, S10).
On the other hand, when the number of homophones is less than 9, each conversion candidate character string is displayed in color in blue (NO in step S9,
S11).

Similarly, in the case of radical conversion processing, if there are nine or more Kanji candidates belonging to the designated radical name, they are displayed in red, and if there are less than nine, they are displayed in blue. .

According to the first modification as described above, the user can easily recognize, especially when there are a large number of homophones or kanji candidates such as nine or more. Thus, when there are a large number of homophones, the user can increase the efficiency of the operation of selecting a desired conversion result by using a function such as the homophone word collective display.

The flowchart of FIG. 6 shows a second modification of the first embodiment. In the second modification, when a plurality of homophones exist, and when a homophone consisting of a compound word exists therein, the display form is further changed.

Specifically, a plurality of words forming the compound word are displayed in different display colors. For example, in the case of a compound word such as "manuscript paper", the first word "manuscript" is displayed in red and the second word "paper" is displayed in blue (YES in step S12, S14, S15). ，
S16). If the third word is present,
The part is displayed in yellow (YES in step S17,
S18).

According to the second modified example as described above, it becomes easy to use the function of designating a certain word of the compound word and displaying the next candidate only for that word by operating the cursor key 2b, for example. . That is, since the user can easily confirm each word of the composite word, it becomes easy to select the next candidate for each word as the conversion candidate. (Second Embodiment) As an application example of the basic operation described above, the second embodiment will be described with reference to the flowchart of FIG.

In the second embodiment, the color information for each type of dictionary designated by the user is registered in the color table 7b by the keyboard 2 and the field designation MMI section 5 (step S1).
9). The conversion candidate display processing unit 1c recognizes the dictionary type from the conversion candidate table 7a when there are a plurality of homophones (step S20). Next, the color information corresponding to the type of the dictionary is searched from the color table 7b (step S21). Then, the conversion candidate character string is displayed in the display color according to the retrieved color information (step S22).

As a concrete example, as shown in FIG.
It is assumed that the user has registered color information for each type of dictionary. The conversion candidate display processing unit 1c recognizes the Japanese history term dictionary (extended 1), which is the corresponding dictionary type, when displaying the first candidate character string "Genji" from the conversion candidate table 7a. In the dictionary of the extension 1, red color information is set by the color table 7b. As a result, the conversion candidate display processing unit 1c color-displays the first candidate character string "Genji" in red.

Similarly, in the main body dictionary, color information of green is set by the color table 7b. Therefore, the conversion candidate display processing unit 1c displays the second candidate character string "original" obtained from the main body dictionary in green.

According to the second embodiment as described above, the user designates a different display color in advance for each dictionary of a specific field (Japanese history term, scientific term, etc.) to use the term of the specific field. When creating a document, it becomes easy to identify a conversion candidate corresponding to the term. Therefore,
A homophone corresponding to the specific field can be easily and surely selected. (Third Embodiment) A third embodiment will be described as an application example of the radical conversion process in the basic operation as described above with reference to the flowchart of FIG.

In the third embodiment, when a phonetic kana character string indicating a radical name is input from the keyboard 2 and the radical key 2c is operated, the kana-kanji conversion control unit 1b executes radical conversion processing. (Steps S30 to S31).

The kana-kanji conversion control unit 1b uses the radical dictionary 3b.
Using, the Kanji candidate character corresponding to the phonetic kana character string is registered in the conversion candidate table 7a (step S32).
Information indicating the radical dictionary 3b is set in the conversion candidate table 7a as the type of dictionary.

Here, in the similar kanji character table 4, as shown in FIG. 3, two types of kanji 1 and kanji 2 which are similar in form to the radical kana kana character string are registered. ing.

The conversion candidate display processing unit 1c refers to the similar Kanji table 4 when displaying the Kanji candidate characters registered in the conversion candidate table 7a (step S33,
S34). If all the kanji candidate characters are not registered in the similar kanji table 4, the conversion candidate display processing unit 1c displays all the kanji candidate characters in green (S3).
6). In this case, as described above, a list is displayed in units of a predetermined number of words.

On the other hand, as shown in FIG. 3, for example, when displaying a kanji candidate character belonging to the radical name "Shinnyu", since kanji 1 and 2 with similar forms are registered, conversion candidates are registered. The display processing unit 1c changes the display color of each kanji candidate character corresponding to the registered kanji 1 and 2.

Specifically, the kanji candidate characters corresponding to kanji 1 are displayed in red, the kanji candidate characters corresponding to kanji 2 are displayed in blue, and all the remaining kanji characters not registered in the similar kanji table 4 are displayed. The kanji candidate characters are displayed in green (step S35).

According to the third embodiment as described above, the display color is changed as described above when there is a candidate Kanji character having a large number of strokes and a similar form during radical conversion processing. The display form makes it possible to prevent selection mistakes. (Fourth Embodiment) A fourth embodiment will be described with reference to the flowcharts of FIGS. 9 and 10 as an application example of the display process using the similar kanji character table 4 as described above.

In the fourth embodiment, as shown in FIG. 2 (C), similar words are registered in the similar word table 7c so that the user can easily make a mistake, and the similar word and the word to be selected are displayed in different display colors. This is a display process.

First, the keyboard 2 and the word registration MMI section 6
Thus, as shown in FIG. 2C, the similar word table 7c
A process of registering a similar word is executed (step S4).
0). That is, when a phonetic kana character string of similar words (“hakaru” as a specific example) is input from the keyboard 2, the kana-kanji conversion control unit 1b causes a plurality of conversion candidate character strings that are the conversion results (as a specific example, A list of "measure" and "promise") is displayed (steps S41 and S42).

The word registration MMI unit 6 operates the keyboard 2 to register the similar word "measure" designated by the user and the word "ai" to be selected in the similar word table 7c (steps S43 and S44).

Next, when shifting to the normal kana-kanji conversion process, the kana-kanji conversion control unit 1b executes the kana-kanji conversion process for the input character string (here, "hakaru"), and the conversion candidate table 7a. Is created (step S4
5, YES, S46, S47).

The conversion candidate display processing unit 1c displays each conversion candidate registered in the conversion candidate table 7a on the display unit 8.
A display process for displaying on the display screen is executed (step S48). In the case of a single headword having no homophone, the conversion candidate is displayed in a black (monochrome) display color (NO in step S49, S50).

On the other hand, as shown in FIG. 2C, when the phonetic kana character string is registered in the similar word table 7c, the conversion candidate "measure" corresponding to the similar word is displayed in yellow (step). YES in S53, S54). In addition, the conversion candidate “Kaku” corresponding to the word to be selected is displayed in red (NO in step S53, S55, S56).

If there are a plurality of homophones and the phonetic kana character string is not registered in the similar word table 7c, the conversion candidate display processing section 1c displays each conversion candidate character string in green color. Perform (NO in step S51, S5
2).

According to the fourth embodiment as described above, the similar word designated by the user and the word which should be mistaken are displayed in different display colors from each other. Therefore, it is possible to prevent the selection error from occurring. The difference from the case of the third embodiment using the similar kanji character table 4 is that the user arbitrarily registers the similar words in the fourth embodiment. Therefore, it becomes possible for the user to register a similar word having a high probability of selection error. (Fifth Embodiment) As an application example of the basic operation in the first embodiment, the fifth embodiment will be described with reference to the flowchart of FIG.

In the fifth embodiment, the conversion candidate Kanji obtained by the Kana-Kanji conversion process is subjected to a display process of changing the display color in accordance with the range of the Kanji group set according to a predetermined rule. .

As a concrete example, a JIS mode showing the range of JIS first level and second level or a common kanji mode showing the range of common kanji and emergency kanji are assumed. First, one of the JIS mode and the common kanji mode is designated by operating the keyboard 2 (step S60).

Next, when the normal kana-kanji conversion process is started, the kana-kanji conversion control unit 1b executes the kana-kanji conversion process for the input character string to create the conversion candidate table 7a (steps S61 and S62).

The conversion candidate display processing unit 1c displays each conversion candidate registered in the conversion candidate table 7a on the display unit 8.
The display process for displaying on the display screen is executed (step S63). Here, if the JIS mode is set,
The conversion candidate display processing unit 1c displays the conversion candidates belonging to the first level in blue (steps S64, S68, S69).
On the other hand, the conversion candidates belonging to the second level are displayed in red (step S70).

When the common kanji mode is set, the conversion candidate display processing section 1c displays the conversion candidates belonging to the common kanji in blue (steps S65 and S66). On the other hand, the conversion candidates belonging to the emergency kanji are displayed in red (steps S65 and S67).

According to such a fifth embodiment, the JIS
Since the kanji included in each range of the mode or the common kanji mode is displayed in different display colors, the user can easily identify which range the conversion candidate belongs to. Therefore, for example, when a document is created using only the first level or common kanji, the operation of selecting only the kanji in these ranges becomes extremely easy.

[0066]

As described above in detail, according to the present invention, in the document creating apparatus having the kana-kanji conversion function, the display colors of a plurality of conversion candidates obtained by the kana-kanji conversion process are changed according to predetermined conditions. The desired conversion candidate can be easily and surely selected by displaying in the display mode.

Therefore, the following concrete effects can be obtained. That is, when there are a plurality of conversion candidates (a plurality of Chinese character candidates belonging to the same phoneme or radical name), the user can easily and surely select a desired conversion candidate. By specifying different display colors for each dictionary,
When creating a document using a dictionary of a specific field, it becomes easy to identify a conversion candidate corresponding to the term.
It is possible to prevent the selection error from occurring when there are Kanji candidate characters having a large number of strokes and similar shapes. It is possible to easily identify a similar word that is erroneously specified by the user and a word that should be originally selected. The user can easily identify whether the conversion candidate is a kanji included in the JIS mode or the common kanji mode.
