Abstract

PURPOSE:To improve the complexity of operation due to the conversion of a different form character. CONSTITUTION:A KANA (Japanese syllabary) character string inputted from a keyboard(KB) 7 is converted by referring a KANA/KANJI (Chinese character) conversion dictionary and the converted character string is displayed on the screen of a CRT 12 as a conversion candidate. On the other hand, whether a reference character form stored in a different form character dictionary or a different form KANJI such as a popular form and abbreviated form is included in the character string or not is checked, and when the corresponding character is included, different form character conversion is applied to the character by referring the different form character dictionary and the converted character string is displayed on the screen of the CRT 12 as another conversion candidate. Since the character included in the different form character dictionary out of characters included in the KANA/KANJI converted character string is automatically processed by different form character conversion, operability following the different form character conversion can be improved.

) Contains kanji code information for individual slang characters, abbreviations, etc. This variant Kanji dictionary (ITAIJDIC) is referred to in order to convert a Kanji in a standard font into a variant Kanji, and to convert a variant Kanji into a Kanji in a standard font or another variant Kanji. In this embodiment, the information in this variant character dictionary (ITAIJDIC) is the character code (JISX0208 code) of the kanji code information of the standard font.
are stored in ascending order according to

For example, for the kanji code information of the standard font "Gaku", if the number of variant character conversions is 3, then 3-1
(=2) Variant kanji code information such as slang characters and abbreviations,
In other words, code information for "學" and "斈" is stored.

FIG. 7 is a diagram showing the structure of the text buffer (TEXT). Text consists of multiple lines of fixed length data. Each line of data is similarly composed of a plurality of character data. Each character data consists of 1 character and 2 bytes. For example, character code JISX02
08. Further, the position of each character is specified by the Y coordinate indicating the line and the X coordinate indicating the character position within the line. For example, in the third line from the beginning of the text, 4 from the left
The character numbered is specified by X coordinate=4 and Y coordinate=3. Similarly, the current position of the cursor is also managed using the X and Y coordinates.

Next, referring to the flowcharts shown in FIGS. 8 and 9, we will explain the kana-kanji conversion process executed by the document processing apparatus of this embodiment, particularly the selection candidate character string converted in the kana-kanji conversion process. The process of converting variant characters to kanji when kanji exists will be explained. Here, it is assumed that kana characters have already been input and some "kana characters" have been stored in the keyboard buffer (KBBUF). First, in step S10, the computer waits for an instruction input from the keyboard (KB) 7. Here, when some input is accepted, the input data is taken into the keyboard buffer (KBBUF) and the process is performed in step S15.
Proceed to. In step S15, the keyboard buffer (K
BBUF) Check what kind of instruction the input data at the beginning is. Here, if the instruction is kana input by pressing the hiragana key, the process proceeds to step S25, and if the instruction is by pressing the conversion key, the process proceeds to step S25.
The process proceeds to step S20, and if any other key is pressed, the process returns to step S10.

In step S25, the "hiragana reading" stored in the keyboard buffer (KBBUF) is read.
Performs processing to add to the reading input buffer (YOMIBUF). Subsequently, in step S30, as shown in FIG. 3A, the "hiragana reading" stored in the keyboard buffer (KBBUF) is additionally displayed in the area (YS) for displaying the reading input for kana-kanji conversion.

In step S20, as will be described in detail later with reference to the flowchart shown in FIG. 9, the kana-kanji conversion dictionary (
Create Kana-Kanji conversion candidates based on the reading input while referring to KNCNVDIC). At this time, it is checked whether or not there are Kanji of the standard font and variant Kanji such as slang and abbreviated characters stored in the variant character dictionary (ITAIJDIC) in the conversion candidate character string. Here, if a corresponding character exists, a conversion candidate character string is created by converting the variant characters in the conversion candidate character string with reference to the variant character dictionary (ITAIJDIC). At the same time, information identifying that the character has been created through variant character conversion is also output to the candidate output buffer (KOUHOBUF).

In step S35, the character string group in the candidate output buffer (KOUHOBUF) created in the kana-kanji conversion candidate creation process in step S20 is converted into the character string group in FIG.
) and as shown in Figure 5(a), the window display screen (
WDSP) and allows the operator of the device to select a desired character string from conversion candidates. Here, the conversion candidate character string created by variant character conversion is highlighted with a shadow, based on the information identifying that it was created by variant character conversion stored in the candidate output buffer (KOUHOBUF). It will be done.

Next, in step S40, the keyboard (K
B) The process waits for an input from 7, and waits for an instruction to select a conversion candidate character string. Here, if any input is accepted, the data is taken into the keyboard buffer (KBBUF) and the process proceeds to step S45. In step S45, the type of instruction stored in the keyboard buffer (KBBUF) is checked. Here, if the given instruction is an instruction to move the cursor using the up/down cursor keys, the process proceeds to step S50, and if the given instruction is an instruction to move the cursor by pressing the selection key, the process proceeds to step S55. If the instruction is , the process returns to step S40.

In step S50, the candidate output buffer (KOUHOBU) created in the kana-kanji conversion candidate creation process is
While displaying the character string group F) on the window display screen (WDSP), move the cursor position on the window display screen (WDSP) for selecting a candidate according to the input of the up and down cursor keys. After that, the process returns to step S40.

In step S55, the character string at the position of the cursor among the character strings displayed on the window display screen (WDSP) is regarded as the selected candidate character string, and the text buffer (TEXT ). Subsequently, in step S60, the process shown in FIG.
) and as shown in Figure 5(c), the window display screen (
WDSP) and erase the text screen (TS).
Display and edit the selected candidate string.

FIG. 9 shows the steps shown in step S20 in FIG.
12 is a flowchart showing detailed processing of kana-kanji conversion candidate creation processing.

First, in step S70, conversion candidates are created for the reading of the reading input buffer (YOMIBUF) by referring to the kana-kanji conversion dictionary (KNCNVDIC).
Output to the candidate output buffer (KOUHOBUF). Next, in step S75, it is checked whether the processing from step S80 onwards has been completed for all conversion candidates created in step S70. Here, if it is determined that the processing from step S80 onwards has been completed for all conversion candidates, the process returns to step S20, and the process returns to step S20.
Processing after 35 is performed. On the other hand, if it is determined that the processing from step S80 onwards has not been completed for all conversion candidates, the processing proceeds to step S80.

[0042] In step S80, for one unprocessed candidate among the conversion candidate character strings created in step S70, a variant character dictionary (ITAIJ) is added to the conversion candidate character string.
Kanji of the standard font stored in DIC), slang and
Check whether there are any variant kanji such as abbreviations. Subsequently, in step S85, the processing result of step S80 is determined. Here, if there are no standard Chinese characters or variant Chinese characters such as slang or abbreviated characters in the conversion candidate character string, the process returns to step S75, and if they exist, the process advances to step S90.

[0043] In step S90, a dictionary of variant characters (ITA
IJDIC), the variant characters in the conversion candidate character string are converted into variant characters to create a conversion candidate character string, and the character string is output to the candidate output buffer (KOUHOBUF). At this time, information identifying that the character has been created by variant character conversion is also stored in the candidate output buffer (KOUHOBUF). After that, the process returns to step S75.

Therefore, according to this embodiment, in the process of performing kana-kanji conversion on an input character string to obtain a desired character string, there are no variants in the conversion candidate character string obtained by referring to the kana-kanji conversion dictionary (KNCNVDIC). Dictionary (ITAI)
Standard kanji or slang characters stored in JDIC)
If there are variant kanji such as abbreviations, the corresponding character will be converted to a variant kanji and displayed, and the variant kanji will be displayed so that the operator of the device can identify that the variant kanji has been converted. The converted string can be displayed with a shadow.

In this embodiment, the conversion candidate character string obtained by referring to the Kana-Kanji Conversion Dictionary (KNCNVDIC) includes kanji, slang characters, abbreviations, etc. in the standard font stored in the Variant Character Dictionary (ITAIJDIC). Although the variant Kanji conversion when there are variant Kanji characters has been described, the present invention is not limited thereto. For example, only when there are kanji in the standard font in the conversion candidate string, or vice versa, slang characters and kanji are included in the conversion candidate string.
It is also possible to perform variant kanji conversion only when a variant kanji such as an abbreviation exists.

In this case, the process in step S80 of the flowchart shown in FIG.
) or "processing to check by referring to the variant character dictionary (ITAIJDIC) whether or not variant characters such as slang characters and abbreviations exist in the conversion candidate character string." , realized.

The present invention may be applied to a system made up of a plurality of devices, or to a device made up of one device. It goes without saying that the present invention can also be applied to cases where the present invention is achieved by supplying a program to a system or device.

[0048]

[Effects of the Invention] As explained above, according to the present invention, it is checked whether or not there are characters included in the variant character dictionary in the inputted hiragana reading string that has undergone kana-kanji conversion, and the corresponding characters are checked. If there is, it can automatically perform variant character conversion and display the converted character string, which reduces the complicated operations associated with variant character conversion and prevents erroneous operations and input errors. It has the effect of Furthermore, since character strings are presented with reference to a dictionary of variant characters, it is possible to improve the rate at which desired character strings can be obtained.
