Abstract

PURPOSE:To allow an operator to easily identify the result of a variant character conversion. CONSTITUTION:A KANA character string inputted by a key board (KB) 7 is converted by referring to a KANA/KANJI conversion dictionary and the converted character string is desplayed on a screen as a conversion candidate. On the other hand, whether there is a reference character style stored in the variant character dictionary and a variant character KANJI such as a popular- form character, an abbreviated character, etc., or not in the character string is investigated. When there is a corresponding character, the character is variant-character-converted by referring to the variant character dictionary and furthermore, the variant-character-converted character string is given a shadow and displayed on the screen as another conversion candidate. Then, it is easy to distinguish between the KANA/KANJI-converted character string and the variant-character-converted character string.

In FIG. 5A, the conversion candidates of "Shijo" converted by referring to the Kana-Kanji conversion dictionary (KNCNVDIC) are first displayed. However, the "article" is
Since there are standard kanji in the variant dictionary (ITAIJDIC), variant kanji such as slang and abbreviations (“jo”)
The conversion candidates (“Shijo”) that have been converted into different glyphs are also displayed. However, the conversion candidates that have undergone the variant transformation are highlighted by halftone dot meshing.

Here, as shown in FIG. 5B, the operator moves the cursor position to "Shijo" with the cursor moving key of the keyboard (KB) 7 and then presses "Select". As shown in FIG. 5 (c), the character string "Shijo" is input to the text buffer (TEXT), and "Shijo" is displayed on the text screen (TS).

FIG. 6 shows a variant dictionary (I
It is the figure which showed the internal structure of TAIJDIC). In FIG. 6, the variant character dictionary (ITAIJDIC) includes variant character conversion number (n) information, reference character kanji code information, (n-
1) It is composed of information on Kanji code of variant characters such as common characters and abbreviations. This variant character dictionary (ITAIJDIC) is referred to in order to convert a standard character kanji into a variant character kanji and to convert a variant kanji character into a standard character kanji or other variant kanji. In this embodiment, the information in this variant character dictionary (ITAIJDIC) is stored in ascending order according to the character code (JISX0208 code) of the kanji code information of the reference character.

For example, if the number of different glyph conversions is 3 for the kanji code information of the standard glyph "Gaku", 3-1
(= 2) Kanji code information of variants such as slang and abbreviations,
That is, the code information of "Gaku" and "Ken" is stored.

FIG. 7 is a diagram showing the structure of the text buffer (TEXT). The text is composed of a plurality of lines of fixed length. Each line data is also composed of a plurality of character data. Each character data consists of 1 character and 2 bytes. For example, character code JISX02
It is stored according to 08. 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, the third line from the beginning of the text and 4 from the left
The first character is designated by X coordinate = 4 and Y coordinate = 3.
Similarly, the current position of the cursor is also managed by this X coordinate and Y coordinate.

Next, referring to the flow charts shown in FIGS. 8 to 9, the kana-kanji conversion processing executed by the document processing apparatus of this embodiment, in particular, the variant characters in the selection candidate character string converted in the kana-kanji conversion processing. An explanation will be given of the variant kanji conversion process when there are kanji. Here, it is assumed that kana has already been input and some "kana character" has been accumulated in the keyboard buffer (KBBUF). First, in step S10, the keyboard (KB) 7
Waiting for an instruction input from. Here, if any input is accepted, the input data is taken into the keyboard buffer (KBBUF), and the process is performed in step S1.
Go to 5. In step S15, it is checked what kind of instruction the input data at the head of the keyboard buffer (KBBUF) is. If the instruction is kana input by pressing the hiragana key, the process proceeds to step S25. If the instruction is by pressing the conversion key, the process proceeds to step S20. If any other key is pressed, the process proceeds. It returns to step S10.

In step S25, the "Hiragana reading" stored in the keyboard buffer (KBBUF)
Processing for adding to the reading input buffer (YOMIBUF) is performed. Succeedingly, in a step S30, as shown in FIG. 3A, "Hiragana Yomi" stored in the keyboard buffer (KBBUF) is additionally displayed in an area (YS) for displaying a kana-kanji conversion reading input.

In step S20, which will be described later in detail with reference to the flowchart shown in FIG. 9, kana-kanji conversion candidates are created based on reading input while referring to the kana-kanji conversion dictionary (KNCNVDIC). At this time, it is checked whether or not the conversion candidate character string includes the kanji of the reference glyph stored in the glyph dictionary (ITAIJDIC) and the glyphs such as slang and abbreviations. Here, if there is a corresponding character, the variant character dictionary (ITAIJDIC)
To generate a conversion candidate character string in which a variant character in the conversion candidate character string is converted into a variant character. At the same time, the information for identifying that the text has been created by the variant 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 shown in FIG.
As shown in (b) and FIG. 5 (a), it is displayed on the window display screen (WDSP) to allow the operator of the apparatus to select a desired character string from the conversion candidates. Here, based on the information that is stored in the candidate output buffer (KOUHOBUF) and that it is created by the variant conversion, the conversion candidate character string created by the variant conversion is highlighted with a shadow. Done.

Next, in step S40, the keyboard (K
B) It waits for the input from 7, and waits for the selection instruction of the conversion candidate character string. Here, if any input is accepted, the data is loaded 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. If the given instruction is an instruction to move the cursor using the up / down cursor keys, the process proceeds to step S50. If it is an instruction to press the selection key, the process proceeds to step S55, except for the up / down cursor keys and the selection key. If the instruction is, the process proceeds to step S40.
Return to.

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

In step S55, the character string at the position of the cursor in the character string group displayed on the window display screen (WDSP) is regarded as the selected candidate character string, and the text buffer (TEXT) is displayed. ) Edit processing. Then, in step S60, as shown in FIG.
As shown in FIGS. 5A and 5C, the window display screen (WDSP) is erased and the text screen (TDSP) is displayed.
The candidate character string selected in S) is displayed and edited.

FIG. 9 shows the step S20 shown in FIG.
It is a flow chart which shows detailed processing of Kana-Kanji conversion candidate creation processing.

First, in step S70, for the reading of the reading input buffer (YOMIBUF), conversion candidates are created by referring to the Kana-Kanji conversion dictionary (KNCNVDIC).
Output to the candidate output buffer (KOUHOBUF). Next, in step S75, it is checked whether or not the processing from step S80 has been completed for all the conversion candidates created in step S70. Here, if it is determined that the processing from step S80 has been completed for all conversion candidates, the processing returns to step S20, and the processing from step S35 described above is performed. On the other hand, if it is determined that the processing from step S80 has not been completed for all conversion candidates, the processing proceeds to step S80.

In step S80, for the unprocessed one of the conversion candidate character strings created in step S70, the variant character dictionary (ITAIJ) is included in the conversion candidate character string.
DIC) standard kanji and slang characters stored in
Check whether there are variant kanji such as abbreviations. Succeedingly, in a step S85, the processing result of the step S80 is determined. Here, the process returns to step S75 if the reference character type kanji and the variant kanji such as slang characters and abbreviations do not exist in the conversion candidate character string, and if they exist, the process proceeds to step S90.

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

Therefore, according to the present embodiment, in the process of performing kana-kanji conversion on the input character string to obtain a desired character string, the conversion candidate character string obtained by referring to the kana-kanji conversion dictionary (KNCNVDIC) is changed. Character dictionary (ITAI
Kanji or slang of standard fonts stored in JDIC)
When there are variant kanji such as abbreviations, the variant kanji is converted and displayed for the corresponding characters, and the variant kanji is displayed so that the operator of the device can identify that the variant kanji conversion has been performed. The converted character string can be displayed with a shadow.

In this embodiment, the kanji or slang or abbreviated characters of the standard font stored in the variant character dictionary (ITAIJDIC) in the conversion candidate character string obtained by referring to the kana-kanji conversion dictionary (KNCNVDIC). Although the variant kanji conversion has been described when there are variant kanji characters, the present invention is not limited to this. For example, only when there is a Kanji character in the standard font in the conversion candidate character string, or vice versa, slang characters in the conversion candidate character string are
It is also possible to perform variant kanji conversion only when there are variant kanji such as abbreviations.

In this case, the process of step S80 of the flow chart shown in FIG. 9 is performed by asking "whether or not there is a reference kanji in the conversion candidate character string, the variant character dictionary (ITAIJDI).
C) ”or“ Process for checking whether or not variant kanji such as slang and abbreviations exist in the conversion candidate character string by referring to variant dictionary (ITAIJDIC) ”
It is realized by changing to.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of one device. Further, it goes without saying that the present invention can be applied to the case where it is achieved by supplying a program to a system or an apparatus.
