Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing device used in a word processor or the like, and more particularly to a document processing device having a document format learning function.

[0002]

2. Description of the Related Art Generally, in a word processor or the like,
The format of the document is specified by setting the number of digits per line. Then, a document is created according to this format, and the created document is printed by the printer. In this case, the character representation is hardware (storage capacity, printer, built-in font, screen resolution, etc.) in display or printing.
There are many parts that depend on, and the characteristics of each word processor come out, but in general, you can use full-width, half-width, 1/4 double-width, double-width double, vertical double-width, and double-width characters for each character or line unit. Pitch can be specified, and many have underline, character decoration, and ruled line functions. In addition, when creating a sentence, many document processing apparatuses can emphasize a particular character or line by underlining or enlarging the character size. These operations are called character modification. Further, in the document processing device, when the produced document is printed out, it can be set in a desired format and outputted. To set such a format, enter or select desired values in the setting items such as pitch between columns, pitch between lines, number of digits per page, number of lines per page, and character points. It is being appreciated. A document is output by a printing device such as a printer based on the format set in this way. Prior to this output, what kind of print output can be obtained in the set format is displayed on the display device. A Japanese word processor equipped with a print image display function for displaying on a display screen is also known.

[0003]

However, in such a conventional document processing apparatus, since the operator can freely set the document format and create the document, the created document is generated. If there are several types,
A plurality of document formats (for example, order information such as "heading" and "date", format information such as underline, character decoration, etc.) are mixed according to the individuality of the operator, which is difficult to read. That is, although various format settings can be made according to individual tastes and purposes, the format must be changed each time another person tries to create a document in accordance with the format of a document created by one person. Iteratively changing such a format decision requires a lot of labor and time. In particular, it is necessary to maintain consistency in the document format for product usage documents and papers / dictionaries edited by multiple people.
In the conventional document processing device, the predetermined number 1
Since the document format of columns (for example, the journal of Information Processing Society of Japan) is converted to the document format of two columns, it cannot be converted to the original document format. Further, in the case of the conventional document processing apparatus, the order of the constituent elements must be input in the order of the constituent elements of the format after conversion, and there is a limitation in the document before conversion. Furthermore, even if the input is done in the order of the constituent elements, it is possible that the indentation, font, character size change, shading, underlining, etc., depending on the level of the title will be different for each person, and a uniform sentence format will be used. It was difficult to do. For example, when there are a plurality of titles in a sentence to be created and indentation (paragraph indentation) is performed according to each title, the degree of indentation may differ depending on the level of the title depending on the person. In this case, it is possible to learn the degree of indentation, but if the size of the paper changes, it will be difficult to see with uniform indentation. An object of the present invention is to make it possible to easily analyze a document format and learn / convert document title symbol information.

[0004]

In particular,
In this embodiment, the structure of a document that has been laid out is analyzed, and character decoration (character type
Learn information by associating information such as font size change, shading, underlining, etc. with its constituent elements. Then, using this learning result, a certain document is character-modified for each constituent element. This makes it possible to easily learn the character modification information of the original document and to easily change the character modification of a certain document by using the learned result of the learned character modification information. In the present embodiment, for the sake of convenience of explanation, it is assumed that only full-width characters are used, and an example sentence in which a plurality of document component block (described later in FIGS. 6 and 7) does not exist in the same line is used.

Document Format Learning Document format learning includes document minimum division processing (FIGS. 6 and 7) and document layout information extraction processing (FIGS. 8 to 1).
1), document arrangement information extraction processing (FIGS. 12 to 16), and learning processing. Further, it is assumed that the document of the input example document 1 shown in FIG. 2 is already stored in the document storage area 28 of the RAM 13.

Document Minimum Division Processing FIG. 6 is a flowchart showing the document minimum division processing for dividing the document data into the minimum blocks in order to analyze the structure of the document, and is shown in FIG. 7 by executing this document minimum division processing. A document minimum divided block table (table 1) is created. In FIG. 6, reference numeral Sn (n = 1, 2,
...) indicates each step of the flow.

First, in step S1, the document data is extracted line by line from the document storage area 28 of the RAM 13, and in step S2, it is determined whether or not the document data could not be extracted.
When the document cannot be taken out, it is determined that the document is at the end and the processing of this flow is ended. When the document can be taken out, the document line take-out pointer is updated in step S3. Then
In step S4, a valid character is searched, and if it is determined in step S5 that there is a valid character, the process proceeds to step S6.
If it is determined that there is no valid character, the process returns to step S1 and the document data of the next line is taken out. Here, data (for example, a space) other than the character data that is regarded as an effective character by the effective character search is skipped. By performing this effective character search, for example, after creating one block if there are two effective characters across a space,
You can create another block in the same row.
Therefore, more blocks may be created than the number of lines of document data. In step S6, the document line position and the start column position are set in the document minimum divided block table (table 1) shown in FIG.
Character search is performed until no input or line feed appears. Next, in step S8, the end digit position is set in the document minimum divided block table (table 1), in step S9 "block attribute (described later)" is set in the document minimum divided block table (table 1), and the process returns to step S4. Then, the above processing is repeated.

By the above document minimum division processing, the RAM 13
In this work area 31, the document minimum divided block table (table 1) as shown in FIG. 7 is created.
This document minimum divided block table (Table 1) is
Document data extracted line by line from the document storage area 28,
Smallest block 1-No input, line feed, space
1, 1-2, ..., 1-5, 1-6, 1-7, 1-8 are divided and stored. As shown in FIG. 7, one block of the document minimum division block table is divided into “document line position”, “start column position”, and “end column position” based on the document delimiter information, and how the document minimum division block is divided. And a "block attribute" indicating whether or not a punctuation mark / title symbol is included, and the above "block attribute", "document line position", "start column position" and "end column position" for each minimum divided block described above. Is set.

The "block attribute" is set by bit information obtained by dividing 8 bits into 4 bits and 4 bits, and the contents for each bit are as follows. That is, in the case of bit information on, “0” includes a punctuation mark, “1” includes a title symbol, “2” is divided by a space, “3” is divided by a non-input / line feed, “4” "Indicates that characters continue to the end of the line, and" 5 "to" 7 "are unused. For example, the block attribute “08H” of the minimum document division block 1-1 is
Bit information of the 3rd bit represented by 8 = 23
It is separated by a line break. " Further, the block attribute "10H" of the minimum document division block 1-5 indicates the bit information of the 4th bit "characters continue to the end of line".
Furthermore, the block attribute “09H” of the minimum document division block 1-6 is obtained by adding the bit information “0” to “08H”. Therefore, the above-mentioned third bit information “divided by non-input / line feed” is used. It is shown that the bit information is “included”.

As described above, in the above document minimum division processing,
The document analysis device 24 takes out the document data line by line from the document storage area 28 and divides the document data taken out line by line into the minimum divided blocks separated by no input, line feed, and space, and the document minimum divided block table ( The table 1) is created in the work area 31. At this time, a block attribute indicating what the document minimum division block is divided into and including a punctuation mark / title symbol is also set.

The document minimum division process will be specifically described below by taking the input example document 1 (FIG. 2) as an example. First, the first line of the document is extracted from the document data of the input example document 1 shown in FIG. 2 and effective characters are searched. In this case, the valid characters are "October 23, 1991", so "Document line position" is "0".
The 1st line, the "start digit position" is the "25" digit, and the "end digit position" is the "34" digit, and these pieces of information are stored in the document minimum divided block table (table 1). Set as 1. Also, since the valid character "October 23, 1991" is divided by a line feed to form a minimum divided block, the "block attribute" is "08H", and the bit information is "3: No input / line feed". "Split" is set. Thus, the first line of the document is first fetched, and the space up to the 24th digit is skipped.
"October 23, 1991" from the digit is the smallest divided block of the document smallest divided block table (Table 1) 1-
It becomes 1. Since this minimum divided block is separated by a line feed, the "block attribute" is "08H". Next, the second line of the document is extracted, but since there are no valid characters in this second line and only lines are included, the minimum divided block is not created. Then, the third line of the document is taken out next.
In the line, there is a valid character "Business trip report" from the beginning, and since it is separated by a line feed, "Block attribute" is "08
"H" and "Document line position" are "03" line, "Start column position"
Becomes the "13" th digit and the "end digit position" becomes the "22" th digit, and these pieces of information are set as the minimum divided block 1-2 of the document minimum divided block table (table 1). In this way, the minimum line of the input example document 1 is analyzed, and all the minimum divided blocks are created.

Document Layout Information Extraction Process FIG. 8 is a flowchart showing the document layout information extraction process for extracting the layout information of the document element from the analysis result of the document data structure. This flow shows whether or not the document minimum division blocks can be connected. This is a process of determining whether or not and assigning a block attribute. By executing this process,
Document component block table shown in 0 (Table 2)
A document layout information table (table 3) shown in FIG. 11 is created.

First, in step S11, the minimum document division block created in the minimum document division process (FIG. 6) is taken out, and in step S12 it is determined whether the minimum document division block has been extracted. When the document minimum division block has been extracted, the extraction pointer is updated in step S13, and it is determined in step S14 whether or not there is a keyword in the extracted document minimum division block character string by referring to the keyword dictionary shown in FIG. To check.

Here, the keyword dictionary is a dictionary of terms peculiar to the document constituent elements and is stored in the ROM 12. The keyword dictionary is classified according to the document constituent element classification, and is one of the elements that determines the constituent element classification of the block at the stage of creating the document constituent element block from the smallest divided block. For example, there is a keyword dictionary as shown in FIG. 9 as an example. The keyword dictionary shown in FIG. 9 includes keywords related to dates “Heisei”, “Showa”, “Meiji”, ..., “Year”, “Month”,
It is provided with "day" and the like, and the keywords "corporation", "limited company", ..., "sales department", "planning department", etc. regarding the destination and sender. By referring to this keyword dictionary, it is checked whether or not there is a keyword registered in the keyword dictionary in the character string of the document minimum division block.
For example, the minimum document division block table (Table 1)
The minimum divided block 1-1 (the block obtained by dividing the first line of the input example document 1 in FIG. 2) is “Heisei”,
There are keywords relating to the date of "month" and "day", and the character string of the block obtained by dividing the fifth line of the input example document 1 in FIG. 2 has a keyword relating to the address and sender of "sales department". Note that it is not possible to immediately determine that it is a predetermined document component block by simply finding the corresponding character string by referring to the keyword dictionary, and by checking the connection state with the next character string / block. For the first time, it can be determined that the block is a document component block. For example, since there is "Heisei" in the character string of the above-mentioned minimum division block 1-1, the above step S1
It becomes a candidate as a keyword of the date information at the keyword check stage of No. 4, and since this character string ends with a line feed, it is consequently a document component block of the date. However, even if the same keyword “Heisei” is registered in the keyword dictionary, for example, in the character string “Heisei” on the 8th line of the input example document 1 in FIG. Since it is determined that the character strings of a normal document are connected, it is not determined to be the document configuration block of the date.

Returning to the document layout information extraction processing flow shown in FIG. 8, when the keyword check is completed in step S14, it is determined in step S15 whether the smallest document divided block taken out of the document is connected to the next smallest document divided block. When connecting, the minimum document division blocks are connected by returning to step S11 and repeating the above processing. If the extracted minimum document divided block is not connected to the next minimum document divided block, the process proceeds to step S17. If there is no minimum document division block in step S12, the process directly proceeds to step S17. In this way, after the keyword is checked and the concatenation of the document minimum division blocks is determined, the document component block can be created, and the document component block table (table 2) shown in FIG. 10 is created. . The position information of this document component block is set in the document layout information table (table 3) shown in FIG. 11 in steps S17 and S18 described below.
That is, in step S17, the "component classification (see FIG. 10)" is determined by referring to the keyword check and the title symbol and the "component classification" is stored in the document component block table (table 2) shown in FIG. At the same time as setting, the "start minimum divided block number" and "final minimum divided block number" determined based on the connection information are set in the document component block table (Table 2), and the "component classification" is set. It is set in the document layout information table (table 3) shown in FIG.
Then, in step S18, the position information of the document component block is stored in the document layout information table (table 3).
, And it is checked in step S19 whether or not there is a minimum document division block to be extracted, and in step S2
If it is determined that there is a next document minimum division block to be taken out at 0, the process returns to step S11 and the same arrangement information extraction processing is repeated for the next document minimum division block.
When it is determined that all the blocks are finished, the process of this flow is finished.

By the above document layout information extraction processing,
The document component block table (table 2) shown in FIG. 10 and the document layout information table (table 3) shown in FIG. 11 are created in the work area 31 of the RAM 13. The document constituent element block table (table 2) classifies the document elements for each of the document minimum division blocks, and classifies the document elements into document constituent element blocks 2-1 and 2-1.
2-2, ..., 2-6 are classified and stored. One block of the document component block of the document component block table (Table 2) is the date as shown in FIG.
It consists of a "component classification" indicating the components of the smallest divided document such as a title, a "start minimum divided block number" indicating the start and end numbers of the minimum divided block, and a "final minimum divided block number". The contents of "classification" are as follows. That is, "01" is the date and "0"
"2" is the creator, "03" is the sender, "04" is the address,
“05” indicates a headline, “06” indicates a preface, “07” indicates a main text, “08” indicates a postscript, and “09” indicates other. For example, the document component block 2-1
Is the smallest divided block having a leading smallest divided block number of “01” (corresponding to the smallest divided block 1-1 in FIG. 7), and this smallest divided block is the document smallest divided block table (table 1 in FIG. 7). As can be seen from the block attribute of), since there is no minimum divided block to be connected next, the final minimum divided block number is “01”. The component classification of this document component block 2-1 is "date" of "01" (see the first line of the input example document 1 in FIG. 2). Further, the document component block 2-2 is the smallest divided block having the head smallest divided block number "02" (corresponding to the smallest divided block 2-1 in FIG. 7), and this smallest divided block is the smallest document. As can be seen from the block attribute of the divided block table (Table 1), there is no minimum divided block to be connected next, so the final minimum divided block number is “02”. The constituent element classification of this document constituent element block 2-2 is "05""majorheading" (see the third line of the input example document 1 in FIG. 2).
Further, the document component block 2-6 is the smallest divided block whose head smallest divided block number is “07” (see FIG.
Corresponding to the minimum divided block 1-8), and this minimum divided block is the final minimum since it is the text as is clear from the 13th line of the input example document 1 in FIG. The divided block number is “21”. The component classification of this document component block 2-6 is "07""text". Here, in this embodiment, in addition to the above, character size information, character modification information, title symbol pattern information, and digit indentation information are provided as individual information, and in particular, the structure of a laid-out document is analyzed and each constituent element is analyzed. Learn the information of character modification (character style, character size change, shading, underline, etc.) that is performed separately by associating it with its constituent elements. Next, using this learning, a certain document is character-modified for each of its constituent elements.

On the other hand, one block of the document layout information block of the layout information table (Table 3) is "positional information" for storing the "component classification" used in the above-mentioned document component block and the order of the block.
The contents of "Location information" are "01" on the left,
"02" is centering, and "04" is right-handed.

As described above, in the document layout information extraction processing, the keyword dictionary and title symbols (for example, 1. 2.,-,
The document component block table (table 2) is created while referring to (○, ☆, etc.), and at the same time, the document layout information table (table 3) storing the position information of the block is created in the work area 31. The order stored in the document layout information table (Table 3) represents the layout order of the document component block on the document. For example, if "date" precedes "major heading" on this document layout information table (table 3), it means that "date" is laid out earlier than "major heading" in the document layout. That is,
Documents that are first divided into the document minimum division blocks are grouped into a certain group, and the block attributes representing the document structure elements and their order (position information) are sequentially arranged in the connected blocks. It should be stored as learning data in Table 3). When the document format conversion described later is performed, the document layout of the document data to be layout-converted is converted according to the document layout information table (Table 3).

The document layout information extraction process will be described in detail below by taking the input example document 1 as an example. First, the first document minimum divided block 1-1 of the document minimum divided block table (table 1) is taken out. Next, referring to the keyword dictionary, it can be seen that the character string of this document minimum block 1-1 includes a keyword regarding "date". This document minimum block 1-1 is "date"
It is determined that the block is a document component block of "date" because it is composed only of the above description and is at the beginning of the document and right-aligned. The next minimum division block 1-2 is separated from the minimum division block 1-1 by one line, and thus is not connected and is regarded as another document component block. At this stage, the document component block 2-1 of the document component table (table 2) having the component classification “01 (date)” is created, and this document component block 2-1 is the minimum division block 1-1. Since it is composed of only "first minimum divided block number" and "final minimum divided block number", "01 (minimum divided block 1
-1) "is set. At the same time, the document layout information block 3-1 of the document layout information table (Table 3) is created, and the component classification information “01
(Date) "and position information" 04 (right) "are set in the document layout information block 3-1. An example in which the smallest divided blocks are connected is line position 08 of the input example document 1. Since characters continue to the end of the line in the smallest divided block 1-5 at the line position 08, they are connected to the next smallest divided block 1-6. Further, from the condition that the minimum divided block 1-6 includes a punctuation mark and is before the text, this document component block is regarded as an introduction, and the document component block 3-5 is created. In this way, the document component block table (table 2) and the document layout information table (table 3) are created.

By creating the document component block table (table 2) and the document layout information table (table 3), learning using the document layout information (arrangement information) can be performed. The document according to the present embodiment. In addition to the document layout information extraction processing described above, the processing device 10 is similar to the layout information extraction processing performed in the document layout information extraction processing in order to enable learning of arrangement information such as format patterns, double-width characters, and underlines. Arrange the processing information (format pattern information,
(Character size information, character modification information, title symbol pattern information, digit indentation information, etc.) extraction processing.

Document Arrangement Information Extraction Process FIG. 12 is a flow chart showing a document arrangement information extraction process for extracting arrangement information of document elements from the analysis result of the document data structure. By executing this process, FIG.
A document arrangement information table (table 4) shown in 6 is created. 13 is a flowchart showing a date pattern learning process for setting the date pattern number in the date format pattern table (table 6), and FIG. 14 is a modification information set for setting the modification information in the document arrangement information table (table 4). It is a flowchart which shows a process.

In FIG. 12, first, in step S21, the document component block of the document component block table (table 2) created in the document layout information extraction processing (FIG. 8) is taken out, and in step S22, the document component block is extracted. It is determined whether or not the product can be taken out. When the document component block cannot be taken out, it is determined that there is no next block, and the processing of this flow is ended. When the document component block can be taken out, the take-out pointer is updated in step S23. Next, the document arrangement information table (table 4) shown in FIG. 16 is shown as "component classification (see FIG. 10)" of the document component block of the document component block table (table 2) extracted in step S24.
Set to. That is, the same component classification information as the “component classification” of the document component block of the document component block table (Table 2) is set in the document arrangement information table (Table 4). Then, in step S23, a "format pattern by component element classification" described later is set in the document arrangement information table (table 4). Next, in step S24, "qualification information" is set in the document arrangement information table (table 4), in step S25 "individual information" is set in the document arrangement information table (table 4), and the process returns to step S21 to set the document arrangement. Repeat the extraction process. In this case, "qualification information (for example,
If there is no "double-width, underline, shading, etc.)", only the modification information size (that is, only the word information) is set. When there is "modification information", the modification information is set in the modification information setting processing flow shown in FIG. Is set. When there is unique arrangement information according to the "document element classification", the arrangement information is set in the "individual information" of the document arrangement information block.

FIG. 13 is a flow chart showing a date pattern learning process for setting the date pattern number in the date format pattern table (see table 6 in FIG. 16) when the component pattern classification type pattern information is a date format pattern. First, in step S31, when the format pattern information for each component classification is “date”, the date pattern number date pattern table (table 4) is compared with the document character string, and when it is determined that there is a date pattern in step S32, it is handled. The date pattern number to be set is set in the date format pattern table, and the processing of this flow ends. Also,
If it is determined in step S32 that there is no date pattern, the process of this flow ends.

FIG. 14 is a flowchart of the modification information setting process for setting the modification information in the document arrangement information table (table 4). First, in step S41, it is checked whether the underline is modified, and in step S4
If it is determined in step 2 that there is underline modification, the underline line type (for example, thin solid line underline, thick solid line underline, etc.) is imported in step S43,
In step S44, the modification information is created based on the acquired information and set in the document arrangement information table (table 4). If it is determined in step S42 that there is no underline decoration, step S45 is performed as it is.
Proceed to. Next, in step S45, it is checked whether or not shading is applied, and if it is determined in step S46 that shading is applied, the type of shading (for example, shading 1, shading 2 etc.) is taken in in step S47, and step S4
In step 8, the modification information is created based on the fetched information and set in the document arrangement information table (table 4). If it is determined in step S45 that there is no shading modification, the process directly proceeds to step S49. Then, it is checked in step S49 if the character size has been changed. If it is determined in step S50 that the character size has been changed, the type of character size (for example, half-width, double-width characters, etc.) is fetched in step S51, and the step In S52, the modification information is created based on the acquired information and set in the document arrangement information table (table 4). If it is determined in step S50 that the character size is not changed, the process directly proceeds to step S53. Finally, in step S53, check whether the font is changed,
When it is determined in step S54 that there is a change in the character style, the type of character style (for example, white characters, shaded characters, etc.) is acquired in step S55, and the modification information is obtained based on the acquired information in step S56. It is created and set in the document arrangement information table (table 4), and the processing of this flow is finished. If it is determined in step S54 that the character style is not changed, the process of this flow is ended.

By the document arrangement extraction processing and the modification information setting processing, the work area 31 of the RAM 13 is displayed in FIG.
Document arrangement information table as shown in (Table 4)
Will be created.

The document arrangement information table (table 4) is stored for each arrangement information block 4-1, 4-2, ..., 4-6 for each of the document constituent element blocks. One block of the document arrangement information block of the document arrangement information table (Table 4) is shown in FIG.
"Component classification", which indicates the components of the document, as shown in
It consists of "format pattern", "decoration information size" and "individual information size", and "decoration information" which is set when there is adornment information, of which "component classification" is the document component block. It is the same as the "component classification". As the contents of the “format pattern”, for example, in the format pattern in which the component classification is “date (October 23, 1991)”, “01” is October 23, 1991 and “0”.
“2” is 1991.10.23, and “03” is others. Also, "qualification information size" and "individual information size"
Is the size (expressed by the number of bytes) of the document arrangement information block that stores the modification information, and is, for example, “000”.
"4" indicates that the size of 4 bytes is secured in this block.

Further, in the individual information portion of the document arrangement information table (table 4), the paragraph indentation information of the arrangement information such as the text and the type of title number (“1.” “”)
Arrangement information specific to the document component block, such as the information (1) is stored.

On the other hand, the "modification information" which is set when there is the modification information is such that the upper 4 bits represent the modification type and the lower 4 bits represent the modification pattern (however, depending on the modification type). For example, for the upper 4 bits, "01" is a character size change, "02" is an underline, "04" is a halftone, and "08" is a font. Also, for example, in the lower 4 bits, "00" is full-width for character size change, underline, halftone, and character style,
Thin solid line, shaded 1, white, "01" is half-width, thick solid line,
Shaded area 2, shaded, “02” is horizontal double angle, thin broken line, shaded area 3, bold character, “03” is vertical double angle, thick broken line, shaded area 4, inverted.

As described above, in the document arrangement extraction process, the arrangement information (format) is set for each of the document component blocks of the document component block table (table 2) created in the document layout information extraction process of FIG. Pattern information, character size information, character modification information, title symbol pattern information, digit indentation information, etc.) are extracted and a document arrangement information table (table 4) is created in the work area 31. Arrangement information unique to the document component classification is stored in the individual information portion of the document arrangement information table (Table 4). FIG. 15 is a flowchart of the digit-reduction information extraction processing for setting the title symbol digit-reduction information in the document arrangement information table (Table 4).
First, in step S61, the title level counter and the title symbol pattern counter are initialized, and the minimum division block extraction pointer is moved to the beginning of the text. Next, in step S62, the minimum divided block indicated by the minimum divided block extraction pointer is extracted, and in step S63 it is checked whether the minimum divided block includes a title part / dependent sentence part, and in step S64, the title part / dependent sentence is included. If it is determined that there is a copy, further step S
At 65, it is checked whether the title level pattern has already appeared. Then, when it is determined in step S66 that the title level pattern is a new pattern, in step S67, the carry-down information is set in the document arrangement information table (table 4), and the title level counter and the title symbol pattern counter are updated. When it is determined in step S64 that there is no title symbol, or when it is determined in step S66 that the title symbol pattern has already appeared, the process proceeds to step S68 described later. Next, in step S68, it is checked whether or not there is a minimum division block that has not been checked since the minimum division block extraction pointer was updated. If it is determined in step S69 that there is a minimum division block that has not yet been checked, the above steps are performed. Proceed to S62. If it is determined in step S69 that all the minimum divided blocks have been checked, the process of this flow ends.

The document arrangement information extracting process will be specifically described below by taking the input example document 1 as an example. First, at the same time that the top document constituent element block 2-1 of the document maximum constituent element block table (table 2) is taken out, a document arrangement information table (document arrangement information block 4-1 is created in the table 49, In the arrangement information table (table 4), the same constituent element classification information as that of the document structural element block 2-1 is set, and then the constituent pattern classification-specific format pattern information is set. Is “date”, the date format pattern classification “01 (“ Heisei ** year ** month ** day ”pattern)” is set in the document arrangement information block 4-1. The next modification information is the document. Upper block No modification is done, so only size "0002 (word information)" including yourself is set, and since there is no individual information as well, " 002 (word information). ”Next, the document component block 2-2 is taken out and information is set in the same manner as the document arrangement information block 4-1, but this block is changed in character size and character modified. Therefore, one information block is created for one piece of modification information, and three information blocks of modification information 1 (horizontal double-width), modification information 2 (thin solid line underline), modification information 3 (bold character) are arranged information of the document. It is set in block 4-2. No arrangement information is set in the document component blocks 2-3, 2-4 and 2-5, so no arrangement information is set. 6 is the text, but here, the title symbol pattern information is extracted and learned as follows: First, the first minimum division block forming block 2-6. However, since it does not include the title symbol, the next smallest divided block 1-8 is taken out. Since the beginning part contains the title symbol "1.",
The information is set as a level 1 title symbol pattern in the document arrangement information table (table 4).
In this case, “1.” stored in the arrangement information table.
"1" in the information of 1 represents a number pattern. Then, "0" (the number of digits from the leading digit position of the body layout) is set as the digit-down digit number information in the document arrangement information table (Table 4) as the level-1 title symbol digit-down information. The next smallest divided blocks 1-9 and 1-10 do not include the title symbol, but include the punctuation mark,
It is recognized as a sentence portion belonging to the level, and the digit-reduction digit number information "3" is set in the document arrangement information table (Table 4). Further, the next smallest divided block 1-11 is taken out. This block contains a title symbol, but since the character string start position and the title symbol pattern are the same as the above-mentioned "1.", no information is stored. The next smallest divided block includes the title symbol "" at the beginning of the character string and is digit-reduced from the level 1 title symbol described above. Drop information "6"
Is stored in the arrangement information table (table 4). In this way, the title symbol pattern is extracted.

Learning Process The learning process is a process of storing the document layout information and the document arrangement information obtained by the above-described process in a form that can be used for document format conversion and the like. That is, the work area 3 is processed by the document analysis device 24 by the above-described processing.
Document layout information table (table 3) and document arrangement information table (table 4) created on
Are stored in the document layout information learning information 29 and the document arrangement information learning area 30, respectively, to perform learning. Contents of the document layout information learning area 29 and the document arrangement learning area 30 are retained even when the power of the document creating apparatus is turned off, and are configured by a non-volatile memory or the like. Further, the learning data of these learning areas 29 and 30 can be stored in the external storage device 20.

As described above, the document minimum division processing (FIGS. 6 and 7), the document layout information extraction processing (FIGS. 8 to 11),
After the description of the document format learning including the document arrangement information extraction processing (FIGS. 12 to 16) and the learning processing is finished, the document format conversion for converting the document format based on the learning information will be described in detail.

Document format conversion Document format conversion is a document structure analysis process (see FIG. 1).
7), document arrangement conversion processing (FIG. 18) and document layout conversion processing (FIG. 19). Further, the learning process described above is completed, and the document format learning information is stored in the document layout information learning area 29 and the document arrangement information learning area 3.
The input example document 2 shown in FIG. 3 is converted according to the learning result of the input example document 1 and output as the output example document 1 as an example.

Document Structure Analysis Process This document structure analysis process is a process of analyzing the document structure of an input sentence and creating a document structure analysis table (table 5) having a block range and a component classification in the work area 31. This document structure analysis process is slightly different from the above-described document minimum division process (FIGS. 6 and 7) and document layout information extraction process (FIGS. 8 to 11) in the format of the resulting table, and the analysis procedure is slightly different. It is almost the same. That is, the document structure analysis table (table 5) can be created by the same processing as the processing flows shown in FIGS. 6 and 8. This document structure analysis table (table 5) is the document component block table of FIG. This corresponds to (Table 2).

The above document structure analysis table (Table 5)
Categorizes the document constituent elements for each of the minimum document division blocks of the input example document 2, and classifies them into the document structure analysis blocks 5-1, 5-2, 5-3, 5-4, 5-5, 5 -6
It is classified and stored for each. In addition, one block of the document structure analysis element block of the document structure analysis block table (Table 5) is a "component classification" indicating a document component such as a date and a title, a "start line position" indicating a block range, and It consists of "end line position".

In the case of document format conversion, only the document structure analysis table (table 5) is required, and the document arrangement information table (table 5) is not necessary. That is, since the format conversion of a document determines the structure of the document by the same means as the format learning, rearranges each constituent element according to the learning information, and further arranges the characters, the document arrangement of the documents to be unified. An information table (table 4) is sufficient. Therefore, it suffices to know what kind of block the block is, and only adds the layout information (arrangement information) and arrangement information created at the time of learning the document format to the block.

Document Arrangement Conversion Processing FIG. 18 is a flowchart of the document arrangement conversion processing for arranging the input document (input example document 2) based on the learned arrangement information. First, the document structure of the input document is analyzed in step S71, the document structure analysis block is extracted from the document structure analysis table (table 5) of the input document in step S72, and the document structure is analyzed from the document structure analysis table (table 5) in step S73. It is determined whether or not the analysis block has been taken out. Here, the analysis of the document structure is performed in the same manner as the document information analysis procedure by the document minimum division processing and the document layout information extraction processing described above. When the document structure analysis block cannot be extracted, it is determined that there is no next block, and the processing of this flow ends, and when the document structure analysis block can be extracted, step S
At 74, the fetch pointer is updated. Then, step S
In block 75, the document arrangement information table (table 4) is searched for a block having the same "component classification", and in step S76, it is checked whether there is format pattern change information. When it is determined in step S77 that the format pattern has been changed, the format pattern is changed in step S78, and when there is no change in the format pattern, the process directly proceeds to step S79. That is, the format pattern is changed from the same constituent block stored in the document arrangement information learning area 30 according to the learning of the document arrangement information block having the same constituent classification information. As a result, the format of the document is changed to the format pattern (for example, the document size) of the document to be subjected to the document arrangement conversion.

Next, in step S79, it is checked whether or not there is modification information. If it is determined in step S80 that there is modification information, character modification is performed in step S81, and the process proceeds to step S82. Proceed to S82. In step S82, it is checked whether or not there is individual arrangement information. When it is determined in step S83 that there is individual arrangement information, individual arrangement is performed in step S84 and the process proceeds to step S85. When there is no individual arrangement information, the process directly proceeds to step S85. move on.
In step S85, the document in which the arrangement conversion such as the format pattern, character modification, and individual arrangement is performed is output to the work area 31 as an intermediate document, the document arrangement conversion in the corresponding block is completed, and the process returns to step S42 to perform the above processing. Repeat until there are no document structure analysis blocks.

As described above, in the above document arrangement conversion processing, the component block at the head of the document structure analysis table (table 5) created by the document structure analysis processing of FIG. 17 is stored in the document arrangement information learning area 30. The same component block of the existing document arrangement information table (table 4) is extracted. Then, according to the learning of the document arrangement information block having the same components stored in the document arrangement information learning area 30, the arrangement of the document (for example,
Change the format pattern, character modification, etc.). The result of this document arrangement conversion is output to the work area 31 in the form of an intermediate document. Here, the intermediate document that is temporarily stored in the work area 31 is a document that has undergone the arrangement conversion of the document but the layout position has not been changed, and is shown in the intermediate example document 1 of FIG. Be done.

The above document arrangement conversion processing will be specifically described below by taking the input example document 2 and the intermediate example document 1 as examples.
First, the first block 5-1 of the document structure analysis table (table 5) of the input example document 2 is taken out. The constituent element classification information of this document structure analysis block 5-1 is “date (01)”, and the document arrangement information block 4-1 stored in the document arrangement information learning area 30 having the same constituent element classification information as this. Arrangements are made according to. The document data “1 stored in the document storage area 28
991.11.15 "is the document arrangement information block 4-
According to the format pattern information of No. 1, "" November 15, 1991
It is changed to "day". Next, although the original arrangement is made according to the modification information and the individual information, the arrangement information is not present in the document arrangement information block 4-1 because it is not arranged. The arranged intermediate document is output to the work area 31. Then block 5-2 is taken out,
Since the corresponding document arrangement information block 4-4 does not have the format pattern information and the arrangement information, the arrangement is not performed and it is output to the work area 31 as an intermediate document. Then block 5-3 is taken out,
Since the corresponding document arrangement information block 4-2 has modification information, it is modified by the modification information and output to the work area 31 as an intermediate document. In the next blocks 5-4 and 5-5, since the document arrangement information blocks 4-3 and 4-5 corresponding to these blocks do not have the arrangement information, the arrangement is not performed and they are output to the work area 31 as an intermediate document. It In the next block 5-6, since the corresponding document arrangement information block 4-6 has the carry-down information, it is output to the work area 31 as an intermediate document while the carry-down position is changed. In this way, the intermediate example document 1 shown in FIG. 4 is created on the work area 31. The intermediate example document 1 is a document obtained by arranging the contents of the input example document 2 (FIG. 3) according to the arrangement information of the input example document 1 (FIG. 2). Therefore, in the intermediate example document 1, the layout position of the input example document 1 is not changed, and only the arrangement information such as the format pattern is changed. For example, the date “199” at line position 01 in the input example document 2
“1.11.15” corresponds to the arrangement information learning “normal year ** month ** day” of the 01st line of the input example document 1 as shown in line position 01 of the intermediate example document 1 “1991 November 1
The arrangement is converted to "5th". In addition, the full-size headline (title) “Business trip report” at line position 03 of the input example document 2
Corresponds to the large headline (title) “trip report” of the double-width underline at line position 03 of the input example document 1 to “trip report” as shown in line position 03 of the intermediate example document 1. The arrangement is converted. In this way, the document after the arrangement conversion other than the document layout (arrangement) conversion is created in the work area 31 as the intermediate example document 1. The intermediate example document 1 created in the work area 31 is the final output example document 1 by the document layout conversion process described below.
The layout is converted to (FIG. 5), and a series of document format learning / document format conversion is completed.

Document Layout Conversion Process FIG. 19 is a flowchart of a document layout conversion process for converting the arrangement of the arranged document after arrangement conversion created in the intermediate document based on the learned document layout information and outputting the final output document. is there. First, in step S91, the document layout information block of the document layout information table (table 3) created in the document layout information extraction processing (FIG. 8) is taken out, and in step S92, it is determined whether or not the document layout information block can be taken out. To do. If the document layout information block cannot be extracted, it is determined that there is no next block, and the processing of this flow is terminated. If the document layout information block can be extracted, the extraction pointer is updated in step S93. Next, in step S94, it is checked whether or not there is a document structure analysis table block of the document structure analysis table (table 5) of the corresponding input sentence, and it is determined that there is a document structure analysis table block of the corresponding input sentence in step S95. In step S96, the corresponding portion of the intermediate document is output to the document storage area 28 as the final document (output example document 1) after the document format conversion, the process returns to step S91, and the above-described processing is performed until there is no document layout information block. repeat. On the other hand, when it is determined in step S95 that there is no document structure analysis table block of the corresponding input sentence, the process returns to step S91 and the above process is repeated.

As described above, in the document layout conversion process, the intermediate document created in the work area 31 by the document arrangement conversion process is the document layout information learning area 2
9 is output to the document storage area 28 according to the document layout information table (table 3) learned in FIG.

More specifically with reference to the intermediate example document 1,
First, the top block 3-1 of the document layout information table (Table 3) is taken out, and the document structure analysis block 5-1 on the document structure analysis table (Table 5) having the same component classification information "date" as that is found. Then, the portion of the intermediate example document 1 in the work area 31 corresponding thereto is output to the document storage area 28. Next, in the document layout information table (table 3), the “large headline” of the document layout information block 3-2 is first output, so the document portion corresponding to the “large headline” of the intermediate example document 1 is output to the document storage area 28. To be done. As a result, the layouts of the "large headline" and the "sender" in the input example document 2 and the output example document 1 are switched. In this way, the layout of the intermediate example document 1 is entirely converted into the output example document 1.
Finally, the intermediate example document 1 having the contents of the input example document 2
Are sorted and output according to the layout information of the input example document 1.

As described above, the document processing apparatus 10 according to the present embodiment analyzes the structure of the document data stored in the document storage area 28 and the document analysis apparatus 24 based on the analysis result of the document analysis apparatus 24. A document arrangement information extraction device 26 for extracting element arrangement information, and a document format conversion device 2 for converting document data into a unified document format based on learning data obtained by learning the extracted information.
7 and a document arrangement information learning area 30 for learning arrangement information extracted by the document arrangement information extracting apparatus 25, and the document analysis apparatus 24 controlled by the CPU 11 stores the document data stored in the document storage area 28. For each line, the document data structure is analyzed, the document arrangement information is extracted from the analysis result, and the document carry-down information performed for each component is learned by associating it with the component to arrange the document. The data is stored in the information learning area 30 as learning data, and at the time of format conversion, the digit-carrying level of the title is converted for each constituent element of the output target document similarly extracted based on this learning data. Document format is converted, and the arrangement information is unified according to the format-converted arrangement information. The data CRT18 and printer 22
Since it is output to, when creating a document,
Arrangement information that has been learned can be used, and the arrangement of document data whose arrangement is not unified can be unified to any document data. Therefore, when it is desired to align the document data having certain arrangement information with the document data having the unified arrangement information, first, the first document data having the arrangement information to be unified is read and the document format learning described above is performed. It suffices to read the second document data (may be plural), similarly learn the document format, and further perform the above-mentioned document arrangement conversion. After that, the same processing may be performed when there are a plurality of document data that are not unified. As a result, the operator only has to specify the document data to be unified,
Arrangement conversion work, which was conventionally specified by the operator, can be significantly reduced. There is also an effect that it is possible to convert another person's document into his own format and make it easier to see. In particular, when it is necessary to maintain the consistency of the document format in product usage documents and papers / dictionaries written by multiple people, arrange information that has been decided in advance is supplied, and according to the arrangement information. Since the document formats can be unified, even if multiple people freely create documents, the arrangement information attached to "Date", "Title", "Sender" etc. is not changed one by one and the workability is greatly improved. Can be made. In addition to unifying the document formats as described above, the digit reduction level of the title performed for each component after unifying the document formats is changed to the digit digit of the title for each component of any document. Since it is possible to unify to lower levels, it becomes possible to create more uniform documents. For example, if there are multiple titles in the created document and each person freely gives a title number corresponding to each title (for example, 1., (1), etc.), each title is classified according to the title level. Can be unified to the paragraph level. Further, although the document processing apparatus 10 of the present embodiment has an effect that the document format can be easily learned, the OCR 16 is used when reading the document data.
It is possible to improve workability by directly reading and encoding a character by using, for example, to perform the learning.

Further, although the document processing apparatus 10 of the present embodiment has an effect that the document format can be easily learned, when reading the document data, the characters are directly read and encoded by using the OCR 16 or the like. It is possible to improve workability by learning.

In this embodiment, the carry-down information is learned and converted by the number of digits, but any learning method may be used as long as it can learn the arrangement information including the carry-down information. Needless to say. For example, a document having a 30-digit document format and a document having a 60-digit digit have different weights represented by the 3-digit carry-down digit. Therefore, between such documents having greatly different format digit numbers, this carry-down information may be learned as a percentage of the document format digit number. For example, when there are an A-digit document and a B-digit document, and the A-digit document has a considerably larger number of digits than the B-digit document, it is more natural to perform layout conversion at a ratio of B / A. Can be unified at the paragraph level of the document.

Further, the classification of the constituent elements and the extraction and learning of the document layout information according to the present embodiment are not always uniformly performed, but a part of the document may be learned and converted. For example, there are A document (a document with "distribution destination", "date (upper right)", "preface", "text", and "conclusion") and B document (a document with "date", "text", and "remarks").
When this A document is learned and its layout is stored and the B document is used as an input sentence, the layout of the A document and the layout of the B document are greatly different, so the B document is not unified by extracting and learning the layout information of the A document. It seems better. Therefore, in such a case, a layout is used in which only the part where "date" is in the upper right of the sentence and "text" is below "date" is used, and the "remark" is under "text". The standard layout may be used.

In the present embodiment, the document component block is set on a line-by-line basis. However, the present invention is not limited to this. By adding structure management on a digit-by-digit basis, two or more document configurations can be formed on the same line. Even if there is an element block, it can be processed in the same manner.

Further, the classification of the constituent elements and the extraction and learning of the document layout information in this embodiment are examples, and it goes without saying that the classification, extraction and learning can be performed in more detail, like the method disclosed in this embodiment. Can be realized by the method of.

Further, in the present embodiment, an example of learning the format of a document having a document layout such as the input example documents 1 and 2 has been shown, but the document is created without considering the layout (the digit reduction etc. is performed. You can also lay out plain text in a learned format.

Further, in the present embodiment, the character modification of the "large headline" has been described as an example, but it goes without saying that learning and format conversion can be performed on all the document constituent elements.

Further, although the format learning data learned by the document format learning function is used in the example of the document format conversion processing of the present embodiment, the present invention is not limited to this, and the format learning data in the external storage device is used as the learning area. Needless to say, it may be called and used.

In this embodiment, the document layout conversion process is performed after the document arrangement conversion process. However, it goes without saying that the layout conversion process may be performed first, and then the arrangement conversion process may be performed. .

Further, in the present embodiment, the document processing device 10
The above is an example in which is applied to a Japanese word processor, but it goes without saying that it can also be applied to all other devices, such as a personal computer, as long as the device has a document format conversion function.

According to the present invention, the document analysis means for analyzing the structure of the document data stored in the document data storage means, and the layout information of the document element are extracted from the analysis result analyzed by the document analysis means. Document layout extraction means, document arrangement extraction means for extracting arrangement information including document carry information from the analysis result analyzed by the document analysis means, and document arrangement for layout information of document elements extracted by the document layout extraction means. Since the arrangement information learning means for learning the arrangement information extracted by the extraction means and outputting it as learning data when creating a document is provided, it is possible to use the learned arrangement information when creating a document. It is possible to unify the arrangement of document data that does not have a uniform arrangement to any document data. Can. In particular, because the title mark carry information performed for each component is learned in association with the component, the learning result is used to identify the title symbol for each component for a document. The conversion can be performed, and the digit-carrying level of the title performed for each component can be unified to the digit-carrying level of the title for each component of any document.
