DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the document creation apparatus of the present invention using the radical conversion method of the present invention. 1
Is an input unit such as a keyboard or mouse for inputting characters and various function commands, 2 is a control unit for controlling each processing unit or the display unit by the data input from the input unit 1, 3 is a kana-kanji dictionary 5 and the co-occurrence dictionary 6, and the radical conversion control unit 4 is used to convert the input character string into a mixed Kana-Kanji sentence. 4 is radical conversion using the radical conversion dictionary 7. Radical conversion control unit for obtaining kanji candidates by means of 5, a kana-kanji dictionary containing information on words necessary for kana-kanji conversion processing, 6 a co-occurrence dictionary containing word-word co-occurrence information, and 7 a Accommodates the data indicating the radical name and the kanji including the radical indicated by this radical name, the relationship between the kanji and the radical included in this kanji, and the data for obtaining the kanji from the radical image. Radical conversion dictionary, 8 consists of LCD or CRT A display unit for displaying an input character string, a kana-Kanji conversion result, etc., 9 is a patterning device for shaping the image data input from the input unit 1 and sending it to the radical conversion control unit 4. It is a document buffer that stores the created document.

Next, the operation of this embodiment will be described. When the user inputs a Hiragana character from the input unit 1 and presses the conversion key, or when data (dots or circles) for starting conversion is input, the control unit 2 passes the input character string to the conversion unit 3. And start this. The conversion unit 3 converts the passed input character string into Kana-Kanji by referring to the Kana-Kanji dictionary 5 and the co-occurrence dictionary 6, and passes the obtained conversion candidates to the control unit 2. Control unit 2
Displays the passed conversion candidates on the display unit 8 and stores them in the document buffer 10 when the candidates are confirmed.
Create a kana-kanji mixed sentence.

Here, when the user is creating a document and the desired kanji cannot be obtained by the usual kana-kanji conversion as described above, when the kanji is obtained by radical conversion, Although the image of the radical of the Kanji is understandable, the radical name may not be known. However, although not described in this example, it is assumed that normal kana-kanji conversion also includes single-kanji conversion.

For example, if the user wants to obtain the Chinese character "potato" by radical conversion, but if the radical name of this "potato", that is, "kusa" is not known, then the user makes an image of the radical at step 201 in FIG. In order to obtain, another kanji character having the same radical as a component, for example, "young", is input to the device by the above-mentioned ordinary kana-kanji conversion. As a result, the other Chinese character is displayed on the display unit 8 as shown in FIG. 3 (A) or FIG. 4 (A).

When the above-mentioned "young" is already present in the created document, it is not necessary to newly input "young", and it is also possible to designate it with a cursor or the like on the screen and use it as the input kanji. Next, the user selects whether or not to specify the required radical part of the kanji input in step 202. If not, the process proceeds directly to step 204 and presses the radical key of the input unit 1. .

On the other hand, when designating the radical portion of the Chinese character, the user operates the input unit 1 in step 203 to display the radical portion used by the input Chinese character as shown in FIG. (Designated as a wedge in this example), the process proceeds to step 205. At this time, the control unit 2 highlights the radical part specified in the input Kanji,
Distinguish from others.

Upon receiving the radical key depression data from the input unit 1, the control unit 2 passes the input Chinese character to the radical conversion control unit 4 and activates it. As a result, the radical conversion control unit 4 determines in step 205 whether or not there is an input Chinese character. If not, the process proceeds to step 213, and if there is, then the step 2
Proceed to 06.

Next, the radical conversion control unit 4 determines in step 206 whether or not the radical part of the input Chinese character is designated. If it is designated, the process proceeds to step 215, and if it is not designated, the step is performed. Proceed to 207.

In step 207, the radical conversion control unit 4 searches the radical conversion dictionary 7 for all radical parts of the input Chinese character, extracts a radical name, and controls it. Deliver to Part 2. The control unit 2 uses the passed radical name as shown in FIG.
It is displayed on the display unit 8 as shown in.

FIG. 7 shows an example of the radical conversion dictionary 7. In the first row from the left, the radical name is the heading, and all the kanji whose constituent elements are this radical name are collected. The configuration of this column is the same as the conventional one. The second column from the left is a kanji heading, and all radical names included in this kanji are collected. In the third row from the left, the radical image is the headline, and the radical name of this radical image is collected. The second stage and the third stage are the configurations adopted for the first time in this example.

The radical conversion control unit 4 executes the above step 20.
7, the second level of the radical conversion dictionary 7 is referred to, and all radical names included in the Kanji of the same heading as the input Kanji are extracted.

Next, the radical conversion control unit 4 determines in step 208 whether or not there are a plurality of extracted radical names,
If not, the process proceeds to step 211 immediately, otherwise to step 209. For all radicals possessed by the kanji entered in step 209, the user selects the batch conversion mode in which the kanji having these radicals as constituent elements are collectively displayed, or the kanji containing a particular radical. Only the non-collective conversion mode for displaying only is selected by operating the input unit 1.

If the batch conversion mode is selected as a result of this selection, the radical conversion control unit 4 immediately proceeds to step 211, and if not, proceeds to step 210. In step 210, the user selects the radical forming the Kanji to be input from the radical names included in the Kanji to be input displayed on the display unit 8 as shown in FIG. Operate and select. As a result, the radical conversion control unit 4 knows the selected radical name.

In step 211, the radical conversion control unit 4 refers to the first stage from the left of the radical conversion dictionary 7 as shown in FIG. 7, and determines the radical indicated by the radical name extracted in step 207. Search for all kanji including. At this time, when the batch conversion mode is selected, the above search is performed for all the extracted radical names. However, when the radical name is selected in step 210, the selected radical name is selected. Only do the above searches.

Since the radical conversion control unit 4 passes the candidate Kanji characters obtained by the search in step 211 to the control unit 2, the control unit 2 shows the candidate Kanji characters in step 212 in the batch conversion mode as shown in FIG. As shown in FIG. 5 (B) in the non-collective conversion mode.

On the other hand, when it is determined in step 206 that the radical part of the input Chinese character is designated, the radical conversion control unit 4 refers to the second stage of the radical conversion dictionary 7 in step 215. After extracting the radical name included in the kanji having the same heading as the input kanji, discarding other radical names, leaving only radical names corresponding to the designated radical part, and step 2
Proceed to 11. The radical conversion control unit 4 refers to the first stage of the radical conversion dictionary 7 shown in FIG. 3 in step 211, and searches for all the kanji including the radical indicated by the radical name extracted in step 215. To do. In this case as well, the candidate Chinese characters searched in step 212 are displayed on the display unit 8 by the control unit 2 as shown in FIG.

When it is determined in step 205 that no kanji has been input, and the process proceeds to step 213, the radical conversion control unit 4 causes the control unit 2 to display a portion as shown in FIG. Display the neck image input screen. The user who sees this inputs the radical image using the mouse or the like of the input unit 1.

When the radical image is input by the input unit 1, the image pattern input unit 9 shapes the input radical image to form a pattern, and then sends it to the radical conversion control unit 4. Here, the above-mentioned patterning means shaping a distorted portion of a straight line or a curved line of an input image to form a beautiful straight line or curved line.

Next, the radical conversion control unit 4 proceeds to step 211 and refers to the third row from the left of the radical conversion dictionary 7 as shown in FIG. 7 to refer to the image pattern of the same heading as the input image pattern. And retrieve the radical name of this image pattern, and then proceed to step 211. The radical conversion control unit 4 refers to the first stage from the left of the radical conversion dictionary 7 as shown in FIG. 7 in Step 211, and includes the radical represented by the radical name extracted in Step 207. Search for all kanji. Since the radical conversion control unit 4 transfers the candidate Kanji characters obtained by the search in Step 211 to the control unit 2, the control unit 2 displays the candidate Kanji characters in the display unit 8 in Step 212 as shown in FIG. To do.

When the candidate kanji is displayed on the display unit 8, the user selects a desired kanji from among them. As a result, the radical conversion control unit 4 sends the selected Chinese character to the control unit 2, and the control unit 2 displays the selected Chinese character in the sentence displayed on the display unit 8 and also in the document buffer 10. Store.

Although the operation is not shown in the flowchart of FIG. 2, if the radical name is known in this example as well, the radical name can be input from the input unit 1 using hiragana or the like. It goes without saying that radical conversion is possible.

According to the present embodiment, when the radical name of the kanji to be input is not known by radical conversion, an appropriate kanji having the same radical as the radical whose name is not known is converted into a normal kana-kanji conversion. After inputting, the radical conversion key can be simply pressed to display a list of all the kanji whose components are radicals whose radical name is unknown. After that, by simply selecting a desired kanji from the kanji displayed in the list, the kanji can be input by radical conversion easily and quickly without knowing the radical name.

When the radical name of the desired kanji to be input is not known but its image is known, the radical image can be constructed by simply inputting the radical image using the keys or the mouse. Since all the kanji used as elements can be displayed in a list, all you have to do is select the desired kanji from this list and enter kanji by radical conversion easily and quickly without knowing the radical name. You can

In step 214 of the above embodiment, the radical name of the input image pattern is obtained from the third row from the left of the dictionary shown in FIG. 7, but the left side of the dictionary shown in FIG. From the third row to the third row, all the Chinese characters having the radical represented by the input image pattern as a constituent element are searched in Step 914 shown in FIG. 9, and the process proceeds to Step 912 to search the Chinese character. Even if is displayed as a candidate Chinese character on the display unit 8 by the control unit 2, the same effect can be obtained.
Also, the same effect can be obtained by using a coordinate input device including a stylus pen and a tablet to input the image of the radical by handwriting.
