Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method and apparatus for inputting and editing symbols used in sentences in document processing in which Japanese sentences are input and edited on a computer.

BACKGROUND OF THE INVENTION Conventional symbol processing methods and apparatus relate to symbol input. Currently, kana-kanji conversion is widely used as a means of inputting characters. However, for characters that cannot be associated with a reading, such as symbols, it is common to have a separate special input mechanism. It is.

For example, if you look at the correspondence table of codes and symbols prepared separately,
Methods such as directly specifying the corresponding code with a number, or displaying a list of grouped symbols and specifying the symbol using a menu selection method are used.By combining these auxiliary input methods, various types of I was inputting symbols.

Problems to be Solved by the Invention However, with the conventional symbol processing method and device as described above, there is a problem in that the user must memorize special input operations and symbol lists.

For this reason, even though symbolic characters were originally defined, substitute characters were often used. For example, the symbol "..." which means continuation is specified in JIS X020.
Although it is defined as a standard code in 8, it is often used as a substitute symbol like "...". As a result, a problem occurred in that the appearance of the calligraphy became sloppy.

In addition, if substitute symbols and original symbols were used together, there was a problem in that the consistency of the expression of the text was lost.

In addition, in information devices such as personal computers,
It is common for each system to use its own custom character symbols using a custom character definition function to define special purpose symbols. However, today, as the need to mutually exchange text data through various media or communication lines increases, a compatibility problem has arisen in which external characters used in one system cannot be read by another system.

In view of the above-mentioned problems with conventional symbol processing methods and devices, the present invention has been developed to input and edit symbols in Japanese sentences with simple operations, and to create sentences that are well-formed and have unified symbolic expressions. It is an object of the present invention to provide a symbol processing method and device that can guarantee the compatibility of text data.

The position information of the searched original symbol on the character string storage unit 11 and the position information of the corresponding record on the symbol relationship storage unit 12 are output. If it does not exist, the process ends.

(3) The symbol conversion 814 extracts the source symbol string and the target symbol string from the designated record on the symbol relationship storage section 12, and replaces the source symbol string at the designated position in the character string storage section 11 with the target symbol string.

The manner in which a symbol string in the text in the character string storage section 11 is converted into a corresponding symbol string will be explained with reference to FIG.

3-a and 3-b are explanatory diagrams showing examples of character strings in the character string storage section 11. FIG. 3-c is an explanatory diagram showing an example of symbol relationship records in the symbol relationship storage unit 12. When the operator instructs "memory conversion" for the character string 3-a using the contents of the symbol relation storage unit 12 of 3-c, the symbol search unit 13 converts the character string 3-a from the second and third lines of 3-a. The symbol strings "meter" and "r millibar" are detected. Next, the symbol conversion unit 14 replaces the target symbol strings “G” and “I4”, and as a result, the contents of the character string storage unit 11 become 3.
- Changes like b.

In this example, a symbol string using standard codes defined by JIS etc. is used as the source symbol string, and a symbol string uniquely defined by various personal computers etc. is used as the target symbol string. This setting may be reversed. In this case, since the source symbol string and the target symbol string are simply interchanged, a description of the operation will be omitted. In this case, the sentence 3-b becomes 3-a
The system-specific external character symbol ' fx
Since J and "go" are replaced with standard katakana codes, highly compatible text data is created as a result.

[Symbol relationship update] (1) The operator uses the input device 17 to update the symbol relationship update unit 1.

It moves up and down in response to the pressing of the "cursor key" 7. Currently, it is located at the beginning of the page with "(Co., Ltd.)". When updating the original symbol string of this record, input the contents of the updated record, that is, "Corporation ■". As a result, the display on the display device 16 changes as shown in 3-d. Input device 17
When you press the "symbol relationship confirmation key" which means to confirm the update, the symbol relationship update unit 15 sorts the contents of the updated symbol relationship record group using the original symbol string as a key. Therefore, the symbol relationship record group is stored in the symbol relationship storage unit 12 as it is.

Second Embodiment FIG. 2 is a block diagram showing the configuration of a symbol processing device in a second embodiment of the present invention.

Reference numerals 11, 12, 13, 14, 15, 16, and 17 in this figure have the same numbers as in the first embodiment, so the explanation thereof will be omitted.

A kana-kanji conversion section 18 converts the kana string on the character string storage section 11 into a kanji-kana mixed string. There are various methods of kana-kanji conversion, but in this embodiment, a continuous clause-baku conversion method is used. A detailed explanation of the kana-kanji conversion itself will be omitted since it is not related to the gist of the present invention.

Regarding the symbol processing device of this embodiment configured as described above, its operation will be described below as ``conversion before confirmation'' in which symbol conversion is performed before kana-kanji conversion is completed, and symbol conversion is performed after kana-kanji conversion is completed. This will be explained separately in "conversion after confirmation."

[Conversion before confirmation] (1) When the operator inputs kana, alphanumeric, or other raw number symbol characters defined on the keyboard from the input device 17, the kana-kanji conversion unit 18 first converts the corresponding character code as is. It is stored on the character string storage section 11. At the same time, the contents are displayed on the display device 16.

(2) Next, when the operator presses the "symbol conversion key" on the input device 17, the symbol search section 13 detects whether the symbol string in the symbol field of the symbol relation storage section 120 exists in the character string storage section 11. search for. If it exists, the position information of the searched original symbol string on the character string storage section 11 and the position information of the corresponding record on the symbol relationship storage section 12 are output to the symbol conversion section 14 . If it does not exist, the symbol conversion process is terminated and control is transferred to 4).

(3) If the corresponding symbol exists, the symbol conversion unit 14 extracts the source symbol string and the target symbol string from the specified record on the symbol relationship storage unit 12, and converts the source symbol string at the specified position in the character string storage unit 11 into the target symbol string. Replace with symbol string.

(4) Next, when the operator presses the "kana-kanji conversion key" on the input device 17, the kana-kanji conversion section 18 converts the kana strings in the character string storage section 11 into corresponding kanji-kana mixed strings, The results are displayed on the display device 16.

(5) The kana-kanji conversion unit 18 presents candidates for the kana-kanji conversion result one after another in response to the "next candidate key" pressed by the operator, and finally finalizes the character string by pressing the "decision key" for kana-kanji conversion. The data is stored in the character string storage unit 11, and the kana-kanji conversion process is completed.

The state of this pre-confirmation conversion will be explained using FIG. 4. 4-
4-c are explanatory diagrams showing character strings stored in the character string storage unit 11 during conversion.

Initially, characters input from the input device 17 are stored in the format 4-a. When steps (2) and (3) are completed and the symbol conversion is completed, the contents of the character string storage section 11 are 4-b.
It changes like this. Finally, in (4), after completing the kana-kanji conversion step (5), the target character string is completed in the character string storage unit 11 as shown in 4-c.

[Conversion after Confirmation] (1) When the operator inputs Gana, alphanumeric characters, and other raw number symbol characters defined on the keyboard using the input device 17, the Gana-Kanji converter 18 first converts them into the corresponding characters. The code is stored as it is on the character string storage section 11. At the same time, the contents are displayed on the display device 16.

(2) Next, when the operator presses the "Kana-Kanji conversion key" on the input device 17, the Kana-Kanji conversion section 18 converts the Kana strings in the character string storage section 11 into corresponding Kanji-Kana-mixed strings. and display the results on the display device 16.

(3) The kana-kanji conversion unit 18 presents candidates for the kana-kanji conversion result one after another in response to the "next candidate key" pressed by the operator, and finally finalizes the character string by pressing the "decision key" for kana-kanji conversion. The data is stored in the character string storage unit 11, and the kana-kanji conversion process is completed.

(4) Next, when the operator presses the "symbol conversion key" on the input device 17, the symbol search section 13 checks whether the symbol string of the original symbol field of the symbol relationship storage section 12 exists in the character string storage section 11. Please search. If it exists, the position information of the searched original symbol string on the character string storage section 11 and the position information of the corresponding record on the symbol relationship storage section 12 are output to the symbol conversion section 14 . If it does not exist, the process ends.

(5) If the corresponding symbol exists, the symbol conversion unit 14 extracts the source symbol string and the target symbol string from the specified record on the symbol relationship storage unit 12, and extracts the source symbol string number symbol at the specified position in the character string storage unit 110. Replace with column.

The state of this definite diameter conversion will be explained using FIG. 5. 5-
FIGS. 5A to 5C are explanatory diagrams showing character strings stored in the character string storage unit 11 during conversion.

Initially, characters input from the input device 17 are stored in the format 5-a. After completing steps (2) and (3), the contents of the character string storage unit 11 will be 5.
- Changes like b. Finally, when the symbol conversion steps (4) and (5) are completed, the target character string is completed in the character string storage unit 11 as shown in 5-c.

As described above, according to this embodiment, kana-kanji conversion and symbol conversion can be performed in different orders.

In the pre-confirmation conversion in this embodiment, the symbol conversion is performed before starting the kana-kanji conversion, but it may be performed at an intermediate stage before the kana-kanji conversion is completed.

As described in detail, according to the present invention, symbols of Japanese text can be easily inputted by operations similar to kana-kanji conversion.

It is also possible to change the substitute symbolic expressions in the text into regular formats to improve the appearance.

Furthermore, the symbols of substitute symbolic expressions and regular expressions present in the text can be unified into a fixed format.

Furthermore, by converting non-standard symbols to standard symbols, compatibility of text data can be guaranteed.
