DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, when character string data is transmitted by a plurality of computers, a line feed character that is forcibly inserted into a character string by a transmission device is removed on the receiving side, and is displayed in a manner that is easy for the user to see. To a character string data processing apparatus and method.

[0002]

2. Description of the Related Art Recently, electronic mail for transmitting text data between computers has been widely used. However, when transmitting an e-mail, the processing method of the communication software does not always match between the transmitting device and the receiving device. For example, the number of characters displayed on one line differs between the transmitting device and the receiving device. There is.

[0003] For example, a transmission-side apparatus forcibly inserts a line feed character at the end of each line of text data to perform transmission processing, and the number of display characters in one line of the transmission-side apparatus is reduced by the reception-side apparatus. If the number of characters is larger than the number of characters to be displayed in one line, the device on the receiving side displays a line with a large number of characters and a line with a small number of characters every other line. Such a display is very difficult for the user to see, it is difficult to grasp the meaning and content of the sentence, and it is difficult for the writer's intention to be conveyed.

[0004] The present invention has been made in view of the above-mentioned problems of the prior art. Even when data is transmitted or exchanged between communication apparatuses having different display processing methods, communication on the receiving side is performed. Character string data processing apparatus and method capable of removing a line feed character inserted in text data forcibly and displaying the text easily and easily for the user The purpose is to provide. Further, the present invention provides a character string data processing apparatus and method capable of accurately and easily transmitting a writer's intention to a communication partner by forcibly removing a line feed character inserted into text data. The purpose is to provide.

[0005]

In order to achieve the above object, a character string data processing apparatus according to the present invention uses a character string data in which a line feed character is inserted later to convert a character string data in which a line feed character is inserted later. A character string data processing device that removes only a linefeed character immediately before the symbol character based on the type of a predetermined symbol character immediately after the linefeed character in the character string data. First line feed character determining means for determining whether or not the character is a line feed character; and a line feed character immediately after the symbol character based on a type of a predetermined symbol character immediately before the line feed character of the character string data. A second line feed character determining means for determining whether or not the character is a subsequent line feed character; Line character, and a character string data processing means for removing processed from the character string data.

Preferably, the apparatus further comprises character string data display means for displaying the character string data from which the subsequent line feed character has been removed.

Preferably, when the symbol character is a predetermined first symbol character, the first line-feed character determining means replaces the line-feed character immediately before the first symbol character with the subsequent line-feed character. And the second line feed character determining means determines that the symbol character is a predetermined second symbol character.
The line feed character immediately before the second symbol character is determined to be the line feed character after the second symbol character.

Preferably, immediately before the line feed character of the character string data is a predetermined first character / symbol character (first character / symbol character), and immediately after the first line / character is the first character / symbol. If the character is not a character, a third line feed character determining means for determining that the line feed character is not a subsequent line feed character; and a predetermined second character character immediately before the line feed character in the character string data, and In the case where is not the second character character, there is further provided fourth line feed character determination means for determining that this line feed character is not a subsequent line feed character.

Preferably, when the number of characters in the line on which the line feed character is present is equal to or less than a predetermined number, the fifth line feed character is determined not to be a subsequent line feed character.
Has a line feed character determination means.

According to the present invention, when text data is transmitted between communication apparatuses having different communication processing systems, or when text data is exchanged via a recording medium between computers having different document processing systems, Based on rules specific to Japanese sentences, the device that receives the sentence data (receiver) should leave line feed data intentionally inserted by the writer in the document data and send the sentence data (sender ) Device removes only the line feed character inserted afterwards at the end of each display line (later line feed character), and displays the sentence data so that it is easy for the user to see and understand the intention of the writer. I do.

[0011] In the character string data processing device according to the present invention, the first line feed character judging means determines that a predetermined symbol character immediately after the line feed character included in the text data (character string data) is unnatural as a head of the line. First symbol character, for example, ",.,.?!-)]"｝ "
In such a case, it is determined that the line feed character immediately after these unnatural symbol characters is a line feed character after.

[0012] The second line feed character judging means determines that the predetermined symbol character immediately before the line feed character included in the text data is a natural second symbol character as the end of the line, for example, ",. )] "｝", Etc., it is determined that the line feed character immediately before these natural symbol characters is not the line feed character after it, but the line feed character inserted intentionally by the writer.

Third line feed character determining means and fourth
Is a means for judging a line feed character inserted intentionally by the writer, particularly in a section that is itemized in the text. The third line feed character determining means determines that a character immediately before the line feed character indicates an item in an itemized list (eg,
1. , 2. ,...), A specific type of character (first character / symbol character, for example, “1, 2” in the above example) often used at the beginning of a line, such as numbers, alphabets, and symbols. Immediately after the line feed character, there are further characters of the same type (for example,
If "." In the above example does not follow, it is determined that there is no textual connection before and after the line feed character, and the line feed character between these characters is replaced with the line feed character that the writer intentionally inserted. judge.

[0014] The fourth line feed character judging means determines that the character immediately before the line feed character is a character character of a specific type such as hiragana, katakana, and kanji (a second character character) used in the sentence of the content of the itemized list. If a character of the same type immediately follows a line feed character, this character is determined to be a subsequent line feed character. In other words, when the character immediately before the line feed character is a character such as hiragana, katakana, or kanji, and a character character such as a number and a symbol character used as a code indicating a bulleted item immediately follows the line feed character. , The line feed character is determined to be a line feed character intentionally inserted by the writer.

The fifth line feed character judging means is a means for judging a line feed character inserted by the writer to intentionally insert a line feed in the middle of the line, wherein the number of characters in the line including the line feed character is constant. If the value is equal to or less than the threshold, it is determined that the line feed character has been intentionally inserted by the writer. The reference value for calculating the threshold value may be, for example, 80 characters of a general 8-bit character (40 characters of 16-bit Japanese characters) as the number of characters displayed on one line of a character display terminal, or an average line feed character of received text data. The number of characters displayed on one line of the transmitting apparatus that can be estimated from the number of characters between the lines is used, and the fifth line feed character determination means determines that the number of characters on the line including the line feed character is 2/3 to 3/3 of these reference values. If it is less than or equal to about 4, it is determined that the line feed character has been intentionally inserted by the writer.

The character string data processing means removes, from the text data, the line feed character determined by the first to fifth line feed character determination means as a subsequent line feed character, and determines that the character is a line feed character intentionally inserted by the writer. Leave a line feed character in the sentence data. The character string data display means displays the sentence data excluding the line feed character determined by the character string data processing means as the subsequent line feed data.

Further, the character string data processing method according to the present invention is a character string data processing method for removing only a newly inserted line feed character (late line feed character) from character string data into which a line feed character has been inserted later. The method, based on the type of a predetermined symbol character immediately after a line feed character of the character string data, determine whether the line feed character immediately before the symbol character is the subsequent line feed character, Based on the type of the predetermined symbol character immediately before the line feed character of the character string data, it is determined whether the line feed character immediately after the symbol character is the subsequent line feed character, and is determined as the subsequent line feed character. The line feed character thus removed is removed from the character string data.

Second Embodiment Hereinafter, a second embodiment of the present invention will be described. Background Description First, the background that led to the implementation of the second embodiment will be described. FIG. 9 is a diagram showing a configuration example of an electronic mail system 32 to which the second embodiment of the present invention is applied. Recently, an electronic mail system for mutually transmitting data between a plurality of computers has been actively used. The electronic mail system 32 is, for example, as shown in FIG. 9, the portable computer 1 shown in FIG.
And a desktop computer 34 that differs from the portable computer 1 in display method and communication processing method.
It is configured to be connected via a telephone line 134.

As described above, the portable computer 1 is small and portable, and the liquid crystal display device 122 is also small. For example, the number of display characters per line is 23 characters. On the other hand, for example, the computer 34 has a large monitor device, and the number of display characters per line is 32 characters.
(Hereinafter the same in the second embodiment).

For example, the computer 34 sends text data having the contents shown in Table 21 (kana kanji data; character string data).
Is transmitted to the portable computer 1 and the portable computer 1 displays the kana kanji data sent without any treatment, the display contents are as shown in Table 22 and the user of the portable computer 1 Is hard to see, and the writer's intention is difficult to understand.

[0103]

[Table 21] (Example of sentence sent from computer 34 to portable computer 1) As described above, when a sentence having a long one line is sent, in a device having a narrow display width, a long line and a short line are alternately displayed. It is hard to read. The line feed instruction generated due to the restriction of the device is irrelevant to the writer's intention and may be deleted. ○ Points to focus on ○ 1. Characters before and after line feed instruction ○ 2. The length of the line before the line feed instruction is ○. … (21) [However, in the table 21, the symbol “△” indicates a line feed character (the later line feed character) forcibly inserted by the computer 34 at the time of transmission, and the mark “改” indicates a line feed character (the line feed character) intentionally inserted by the writer. (Intentional line feed character) (the same applies to each table of the second embodiment). ]

[0104]

[Table 22] (Example 1 of display screen of portable computer 1) When a sentence having a long line is sent as described above, in a device having a narrow display width, a long line and a short line are alternately displayed and it is very difficult to read. . The line break instruction generated due to the restriction of the device is not related to the writer's intention and may be deleted. ○ Points to focus on ○ 1. Characters before and after line feed instruction ○ 2. The length of the line before the line feed instruction is ○. ○… (22)

On the other hand, for example, when the portable computer 1 deletes and displays all the line feed characters of the kana-kanji data sent from the computer 34, the display contents are as shown in Table 23. 1
It is difficult for other users to see, and the intention of the writer is difficult to understand. The troubles shown in Tables 22 and 23 also occur, for example, when data is exchanged between the computer 34 and the portable computer 1 using a medium such as the IC card 110.

[0106]

[Table 23] (Example 2 of display screen of portable computer 1) When a sentence having a long line is sent as described above, in a device having a narrow display width, a long line and a short line are alternately displayed, and it is very difficult to read. Line feed instructions generated due to device restrictions are irrelevant to the writer's intention and may be deleted. The points to focus on are: 1. Characters before and after a line feed instruction This is the length of the line before the line feed instruction. … (23)

The second embodiment of the present invention eliminates the above-described problems in the electronic mail system and the like by performing character string data processing based on rules specific to Japanese sentences, and improves the display method and communication processing. However, even when data is transmitted between a plurality of different devices, it is intended to realize a data display that is easy for a user as a reader to see and that allows the writer to easily understand the intention.

[0108] block diagram 10 of a software, a portable computer 1 of ROM shown in FIG. 1
FIG. 3 is a diagram illustrating a configuration of communication processing software 4 according to the present invention, which is stored in a storage unit 102 and executed by the microprocessor 100 to realize a line feed character deletion function. As shown in FIG. 10, the communication processing software 4 includes the Japanese processing software 2 (FIG. 2), the transmission processing unit 40, and the reception unit 4.
2, the receiving unit 42 includes a receiving processing unit 420, a syntax analyzing unit 422, and a line feed character deleting unit 424.

The communication processing software 4 is different from the computer 34 having a different communication processing system depending on these components.
When text data is received from (FIG. 9), the portable computer 1 leaves intentional line feed data, and deletes and displays only the subsequent line feed characters as much as possible.

The operation of each component of the communication processing software 4
The work transmission processing unit 40 uses the Japanese processing software 2 to
The kana-kanji data created as shown in the first embodiment is transferred to the computer 34 (FIG. 9) via the telephone line 134.
Send to The reception processing unit 420 is transmitted from the computer 34 via the telephone line 134,
The kana kanji data as shown in (1) is received, and the parsing unit 4
22 and a line feed character deletion unit 424.

[0111] Line feed character deletion section 424 deletes the intentional line feed character included in the kana kanji data input from reception processing section 420 and deletes the subsequent line feed character based on the determination result of syntax analysis section 422. To display on the liquid crystal display device 122.

The syntax analysis unit 422 processes characters / symbols (character characters, symbol characters) before and after a line feed character included in the kana / kanji data input from the reception processing unit 420 based on the rules of Japanese sentences. It is determined whether each line feed character is an intentional line feed character inserted intentionally by the writer or a line feed character inserted by the computer 34 in the transmission process, and is output to the line feed character deletion unit 424. .

Determination Processing in Syntax Analysis Unit 422 The determination processing of a line feed character in the syntax analysis unit 422 will be described in detail below. The syntax analysis unit 422 determines that the symbol character immediately after each line feed character included in the kana-kanji data is an unnatural symbol character (first character) as the head of the line.
Symbol character), for example, ",.,.?!
-)] If "｝" or the like, it is determined that the line feed character immediately after these symbol characters is a line feed character after the symbol character.

Also, the syntax analysis unit 422 determines that the predetermined symbol character immediately before each line feed character is a natural symbol character (second symbol character) as the end of the line, for example, “,. If “｝” or the like, it is determined that the line feed character immediately before these symbol characters is not a line feed character after but a intentional line feed character.

Further, the syntax analysis unit 422 performs the following determination processing, particularly, for a part that is itemized in the text. The syntax analysis unit 422 determines that the character immediately before each line feed character is a specific character such as a number or alphabet that is frequently used at the beginning of a line as a code (eg, 1, 2,. Even if it is a character character of a type and a symbol character (a first character / symbol character, for example, the portion of “1, 2,...” In the above example), immediately after the line feed character, If a character (for example, “.” In the above example) does not follow, it is determined that there is no textual connection before and after the line feed character, and a line feed character between these characters is regarded as an intentional line feed character. judge.

The parsing unit 422 determines that the character immediately before the line feed character is a character character (a second character character) such as hiragana, katakana, and kanji used in the text of the contents of the itemized list. If a character of the same type immediately follows the line feed character, this character is determined as a subsequent line feed character. In other words, the parsing unit 422 determines that the character immediately before the line feed character is a character character such as hiragana, katakana, and kanji, and that a character such as a number used as a code indicating a bulleted item immediately after the line feed character. If a character and a symbol character continue, this line feed character is determined to be an intentional line feed character.

Further, in order to determine the line feed character inserted by the writer to intentionally insert a line feed in the middle of the line, the syntax analysis unit 422 determines that the number of characters in the line including the line feed character is a fixed threshold [second In the embodiment, for example, if the number of characters is equal to or smaller than 25 characters of 16-bit Japanese characters, the line feed character is determined to be an intentional line feed character. As a reference value for calculating the threshold value, for example, a typical number of display characters per line of a character display terminal is 80 characters (for an 8-bit character, 1 character is used).
40 characters in the case of a 6-bit Japanese character) or the number of characters per line of the transmitting device that can be estimated from the average number of characters between the line feed characters of the received sentence data. The number of characters in the line including the line feed character is 2/3 to 3 of these reference values.
If it is about / 4 or less, it is determined that this line feed character is an intentional line feed character.

Still referring to FIG. 11, syntax analysis section 42
The process 2 will be described. FIG. 11 is a flowchart showing a line feed character determination process of the syntax analysis unit 422 shown in FIG. As shown in FIG. 11, step 200 (S
200), the syntax analysis unit 422
It is determined whether or not the symbol character immediately after the line feed character included in the kana kanji data input from 20 is an unnatural symbol character (the first symbol character) at the beginning of the line. If it is the first symbol character, the process proceeds to S214, and if it is not the first symbol character, the process proceeds to S202.

In step 202 (S202), syntax analysis section 422 determines whether or not the predetermined symbol character immediately before the line feed character is a natural symbol character (the second symbol character) as the end of the line. I do. S for the second symbol character, Kuta
Proceed to 216. In step 204 (S204), the syntax analysis unit 422 determines whether the character immediately before the line feed character is a numeric character, alphabetic character character, and symbol character (first character / symbol character). If it is the first character / symbol character, the process proceeds to S206, and if it is not the first character / symbol character, the process proceeds to S208.

In step 206 (S206), the syntax analysis unit 422 determines whether the character immediately after the line feed character is a numeral, a character character of the alphabet, and a symbol character (first character / symbol character). S20 if the character is the first character / symbol character
The process proceeds to step S8, and if the character is not the first character / symbol character, the process proceeds to step S216. Step 208 (S20
In 8), the syntax analysis unit 422 determines whether the character immediately before the line feed character is a character character (the second character character) such as hiragana, katakana, and kanji. S if not the second character
The process proceeds to 212, and if the character is the second character, the process proceeds to S210.

In step 210 (S210), syntax analysis section 422 determines whether or not the character immediately after the line feed character is the second character character. Second
If the character is not the second character, the process proceeds to S216. In step 212 (S212), the syntax analysis unit 422 determines whether the number of characters in the line including the line feed character is equal to or smaller than a certain threshold (25 characters). If it is less than 25 characters, the process proceeds to S216, and if it is more than 25 characters, the process proceeds to S214.

In step 214 (S214), the syntax analysis unit 422 determines that the line feed character determined in each of steps S200 to S212 is a subsequent line feed character, and deletes the line feed character that has received this determination. The unit 424 deletes the line feed character that has been determined. In step 216 (S216), the syntax analysis unit 422 determines whether or not all of the kana-kanji data received by the reception processing unit 420 has been processed. If the processing is completed, the processing is terminated. If the processing is not completed, the next line feed character is detected, and the process proceeds to S200 with the detected line feed character as a processing target.

[0123] In the communication processing software 4 Operation transmitting operation portable computer 1 of the portable computer 1 (Fig. 1) (Fig. 10), Japanese processing software 2,
In accordance with the operation of the user, the kana-kanji data is generated as shown in the first embodiment. The transmission processing unit 40 transmits the kana-kanji data generated by the Japanese processing software 2 to the computer 34 (FIG. 9) via the telephone line 134.

Reception Operation In the communication processing software 4 of the portable computer 1, the reception processing unit 420 receives the kana-kanji data transmitted from the computer 34 via the telephone line 134. The syntax analysis unit 422 performs the processing shown in FIG.
It is determined whether each new-line character included in the received kana-kanji data is the next new-line character. The line feed character deletion unit 424 deletes the line feed character determined by the syntax analysis unit 422 as a subsequent line feed character from the kana kanji data and displays the character on the liquid crystal display device 122.

When the line feed character included in the kana-kanji data shown in Table 21 is deleted and displayed on the liquid crystal display device 122 by the operation of the receiving unit 42 of the communication processing software 4 described above, the result is as shown in Table 24. In addition, the display content is easy for the user of the portable computer 1 to see and the intention of the writer is easy to grasp.

[0126]

[Table 24] (Example 3 of display screen of portable computer 1) When a sentence having one long line is sent as described above, in a device having a narrow display width, a long line and a short line are alternately displayed and it is very difficult to read. Line feed instructions generated due to device restrictions are irrelevant to the writer's intention and may be deleted. ○ Points to focus on ○ 1. Characters before and after line feed instruction ○ 2. The length of the line before the line feed instruction is ○. ○… (24)

By appropriately modifying the line feed character deletion function shown in the second embodiment, the transmission processing unit 40 (FIG. 10) of the portable computer 1 forcibly outputs a line feed character for each line. When transmitting data by inserting the data, the portable computer 1
It can also be applied to the purpose of deleting a line feed character that has been forcibly inserted.

Third Embodiment Hereinafter, a third embodiment of the present invention will be described. Background Description First, the background that led to the third embodiment will be described. For example, when Japanese document processing is performed by the portable computer 1 shown in FIG. 1 in the first embodiment, as shown in Table 3 and the like, the target area is further divided into phrases, and kana-kanji characters are divided into phrases. Perform conversion processing. At this time, for example, as shown in Table 3, if a character indicating the symbol "|" is inserted between the phrases to display the boundaries of the phrases, only the sentence of the inserted character cannot display the original characters, and , The symbol "|" originally included in the sentence data,
It cannot be distinguished from the symbol "|" indicating between clauses.

Further, for example, when a boundary of a phrase is displayed with a continuous underline between each character in the phrase and an underline interrupted between the phrases, the display area of the liquid crystal display device 122 of the portable computer 1 is displayed. If the resolution is not sufficient, it is difficult for the user to determine whether the underline is broken or not.

In the Japanese language processing, it is necessary to distinguish between the phrase currently subjected to kana-kanji conversion and the other phrases at the time. For example, these phrases are separated by two types of underlines. When displayed separately, if the display area and the resolution of the liquid crystal display device 122 of the portable computer 1 are not sufficient, it is difficult to distinguish between the two types of underlines.

The third embodiment of the present invention solves such a problem and, when performing Japanese processing, displays the segmented sentence data on a small display screen with good visibility to the user. This is intended to improve the efficiency of the processing operation.
