Abstract

PURPOSE:To prevent a comment from suddenly disappearing at the time of transferring it by distinguishably storing comment information whose transfer is disabled at the time of automatically transferring the comment between documents. CONSTITUTION:A comment appending position in an old document is extracted based upon comment appending position information included in comment information stored in an old document file 51 and stored in a character string area 43. An equivalent part evaluated as a part having meaning contents equivalent to the comment appending position is retrieved from a new document file 53. When the equivalent part is retrieved from the file 53, comment information is constituted by using the equivalent part as comment appending position information and stored in a new document comment file 54. If the equivalent part is not retrieved from the file 53, the commen information is stored in a drop-out comment file 55.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a comment adding method for adding a comment to a document and a document processing apparatus using the comment adding method.

[0002]

2. Description of the Related Art Conventionally, it has been considered that a user gives some kind of comment to a part of a document (for example, a manual) stored in a floppy disk or the like. FIG. 16 is a diagram showing an example of a document to which a comment is added (hereinafter referred to as an original document) and a state in which the comment is displayed. On the CRT screen 160,
Two windows are displayed. The text window 161 displays the original document, and the comment window 162 displays the comment. Therefore, the original document and the comment are displayed in separate windows, and a line 163 connecting the windows indicates where the comment is added to the original document.

In this case, as a method of adding a comment to the original document, there is a method of embedding a special code as link information in the data of the original document. The comment is linked to the original document by the link information embedded in the original document, and the comment can be displayed by following this link information. Therefore, in the method of embedding the link information in the original document, the user who makes the comment needs the authority to embed the link information in the original document. Also, the original document file will be viewed by the same comment no matter which user opens it, and it will be viewed by another person if a comment is added. And the content (text) of the comment may be stored in the same file as the original document,
It may be different.

As a method in the case of considering a user who cannot change the original document, the original document and the comment are stored in separate files (the original document file and the comment file), and the ids of both files are displayed at the time of display. There is also a method of booting the system by giving (file name etc.) and combining and displaying them. In this case, the comment file side has information about which part of the original document the comment corresponds to. For example, the position of the comment corresponding to the character from the beginning of the original document file indicates the correspondence with the original document.

In this method, each user can have a comment file separately, and the original document file is shared by all users. Therefore, it is not necessary to have the authority to change the original document file, and it is possible to view the document while seeing only the comment added by oneself without seeing the comment added by another person. Needless to say, it is also possible to read a document while seeing the comment added by another person, as long as the file of the comment added by another person can be read.

[0006]

In the above-described conventional example, the number of characters from the beginning of the original document file is used as the position information indicating where in the original document the comment is added, or a special character is included in the original document data. The method of embedding a code (mark) is used. Therefore, the position information of the comment and the state of the original document file are closely related. For this reason, when a part of the original document is changed to a new version and becomes a completely different document in terms of data, even if the contents are similar, the comments that have been added until then. There was a problem that all were invalidated.

For example, when a comment is added using the link information, when the changed document (new document) is provided as a new document file, the link information is embedded in the provided new document file. Therefore, it is necessary to re-embed the special code as link information. When the number of characters from the beginning of the document is used as the comment position information, if there is a change in the provided new document that causes an increase or decrease in the number of characters, the position (number of characters from the beginning) to which the comment should be added will be changed after that. Because they are different
In the position information of the comment file for the document before change (old document), the comment is not added to the correct position of the new document.
Therefore, also in this case, it is necessary to change the position information of the comment.

[0008] In particular, in the case of manuals that are upgraded by some small corrections or addition of sentences,
The contents of the new document after the version upgrade are not significantly different from the contents of the old document before the version upgrade. Therefore, the comment for the old document has the same meaning for the new document. However, in the above-mentioned conventional technique, since the data of the original document is rewritten, the problem that old comments cannot be utilized frequently occurs. Then, when the comment of the old document is to be used as the comment of the new document, the work of transferring the comment is required, which causes a very troublesome work.

In order to solve the above-mentioned problem, the comment is re-added to the part of the second document which is evaluated to be a part which is semantically equivalent to a certain comment-added position of the first document. A comment adding method and a document processing apparatus that automatically transfer comments between documents have been proposed. However, in the above-mentioned proposal, when the same part as the commented part in the first document cannot be detected in the second document, the comment added to the first document is Is not reflected in the document. Therefore, as a result of changing the document, there is a problem that some comments are erased before they know it.

The present invention has been made in view of the above problems, and when the comments are automatically transferred between documents, the comment information for which the transfer could not be executed is distinguished and saved. Thus, it is an object of the present invention to provide a comment giving method and a document processing apparatus that prevent the comments from being unintentionally lost when the comments are transferred.

[0011]

A document processing apparatus according to the present invention for achieving the above object has the following configuration.
That is, in a document processing apparatus having a function of adding a comment to a document, a storage unit that stores first comment information that associates the comment content of the first document with the comment addition position information, and the comment. An equivalent part search means for searching the second document for a part evaluated to be the same part as the comment added part of the first document based on the added position information, and the second part searched by the equivalent part search means. First storing means for storing second comment information in which the position of the equivalent part of the document is the comment addition position information for the comment content, and the second part by the equivalent part searching means of the first comment information. Second storage means for separately storing comment information for which an equivalent portion has not been searched for in the document.

Further, the comment giving method according to the present invention, which achieves the above object, includes the following steps. That is, in the comment giving method for giving a comment to a document in an information processing device or the like, a storage step of storing first comment information in which the comment content for the first document and the comment giving position information are associated with each other. And an equivalent part search step of searching the second document for a part that is evaluated to be equivalent to the comment added part of the first document based on the comment adding position information, and the equivalent part search step. A first storing step of storing second comment information in which the position of the equivalent portion of the second document is the comment addition position information for the comment content, and the equivalent portion searching step of the first comment information According to the second document, the second storage step of separately storing the comment information in which the equivalent portion is not searched in the second document is stored.

[0013]

In the above structure, the comment-added portion of the first document is extracted from the comment-added position information of the first comment information, and the equivalent portion evaluated to have the same meaning as the comment-added portion Search from the second document. If an equivalent part is found in the second document,
Second comment information in which this equivalent portion is used as comment addition position information is generated, and this is used as comment information for the second document. On the other hand, if the equivalent part is not found in the second document, the comment information is distinguished and saved.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

<Embodiment 1> In Embodiment 1, when a comment of an old document is transferred to a new document, a portion having the same meaning as the old document cannot be detected from the new document, and this is dealt with. 1 for the comment (there may be multiple)
Store in one file. This informs the user which comment could not be transferred.

In the first embodiment, a full-text matching method is used as one method for detecting a portion having the same meaning as the old document from the new document. That is, the part in the new document, which is the same character string as the part of the old document to which the comment is added, has the same meaning.

FIG. 1 is a block diagram showing the schematic arrangement of the document processing apparatus according to the first embodiment. In the figure, reference numeral 1 is a console, and an example of the device configuration is shown in FIG. A keyboard 11 and a mouse 12 are provided as input devices. Further, a screen display device such as a CRT 13 is provided as an output device. Reference numeral 2 denotes a CPU, which controls the entire document processing apparatus. A ROM 3 stores various programs executed by the CPU 1. 4 is a working memory,
The CPU 1 is provided with various areas used when executing a comment transfer process. Reference numeral 5 denotes a file memory, which has an area for storing various document files and comment files. Each of the above components is connected to the computer bus 6 and exchanges data with each other.

Various areas in the work memory 4 will be described. A position information area 41 stores the position information of the comment read from the old document comment file 52. A comment content area 42 stores the content (character string or the like) of the comment read from the old document comment file 52. 43 is a character string area, and in the old document file 51, the position information area 42
The character string of the portion indicated by the position information stored in is stored. Reference numeral 44 denotes a candidate area, which stores the position information of the portion having the same character string as the character string stored in the character string area 43 from the new document file 53 as a candidate for the comment addition position. 45 is position information selected from the candidate area 44 by a predetermined rule.

Various files in the file memory 5 will be described. An old document file 51 stores the old document file before the change. Reference numeral 52 is an old document comment file, and the old document file 51
This is a file that stores comment information attached to.
A new document file 53 is a new document file obtained by changing the contents of the old document file 51. Reference numeral 54 is a new document comment file, in which comment information attached to the new document file 53 is stored. Reference numeral 55 is a dropout file, which stores comment information for which replacement has failed when replacing comments.

Next, an example of how to add a comment to the original document by the document processing apparatus according to the first embodiment will be described with reference to FIGS. 3 and 4. Here, one comment file corresponds to one document, and the document is a normal text file.

FIG. 3 is a diagram showing a storage state of an old document file for storing old documents. FIG. 4 is a diagram showing a storage state of comment information in the comment file.

The correspondence between the document file and the comment file can be made as a comment file name by adding a certain extension to the document file name.
For example, the comment file name for the document doc is doc. It may be a comment or the like. And
The content of this comment file has comment information consisting of a pair of position information and comment content for each comment, and a plurality of such comment information are arranged.

The comment is attached by designating a certain range of the original document. This range is specified by the number of characters from the beginning of the original document file. For example, in the original document shown in FIG. 3, when a comment “Mami Mumemo” is added to the part “Kakikukeko” and a comment “Hahifuheho” is added to “Sashisuseso”, The contents are as shown in FIG. That is, the comment information is one by one for <comment> and </ commen
It is sandwiched between the character strings t>. In this <plac
Position information (the number of characters from the beginning of the document file) sandwiched between e> and </ place>, and <content>
The comment contents (comment itself) sandwiched between and </ content> are inserted.

In the case of the comment file shown in FIG. 4,
The first comment indicates that a comment "Mamimumemo" is attached to the character string from the beginning to the 7th to 11th characters ("Kakikukeko") of the document file shown in FIG. ing. Also, as the second comment, indicate that the comment "Hahifuheho" is attached to the character string ("Sashisuseso") from the beginning of the document file to the 13th to 17th characters. There is.

When the document file and the comment file shown in FIGS. 3 and 4 as described above exist, this document is displayed as shown in FIG. FIG. 5 is a diagram showing a display state of the display screen of the CRT 13. Document window 5
At 11, a display based on the document file 51 of FIG. 3 is made. Further, in the comment windows 512 and 513, a display based on the contents of the comment file is made. Furthermore,
Lines 514 and 515 connecting the document window and the comment window are displayed based on the position information in the comment file.

Next, a comment transfer process performed by the document processing apparatus according to the first embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating a comment transfer process procedure performed by the document processing apparatus according to the first embodiment.

First, in step S201, the commented position information and the comment contents thereof are read from the old document comment file 52, and the position information area 42 and the comment contents area 42 of the working memory 4 are read out.
To store. Next, in step S202, the character string with the comment is extracted from the old document file 51. This can be achieved by simply extracting from the old document file 51 the portion indicated by the position information shown in the old document comment file 52. The extracted character string is stored in the character string area 43 of the work memory 4. Further, in step S203, the new document file 53 is searched for the same character string as the character string stored in the character string area 43. As a result of the search, if the same character string is found,
The number of characters and the number of characters in the new document file 53 are calculated. Then, the calculated two sets are stored in the candidate area 44 of the working memory 4 as the comment addition position candidates. This search is new document file 53
If there are a plurality of character strings suitable for the search in the new document file 53, a plurality of candidates are stored in the candidate area 44.

In step S204, step S203
It is determined whether or not one or more candidates have been found in step S205. If found, step S205 follows. If not found, step S208 follows.

In step S205, the old document file 5
The position of the comment attached in 1 (position information area 4
(Stored in 1) is selected from the candidates, and this is stored in the new position information area 45 of the working memory 4 as the position information of the comment for the new document file. As a criterion of the above-mentioned proximity, here, a candidate numerically close to the position information corresponding to the old document file 51 stored in the position information area 41 is selected.
For example, there is a comment added up to "35th to 42nd characters" of the old document file 51, and candidates are "45th to 52nd characters" and "10th character".
If there is a "5th to 112th character", the candidate "45th to 52nd character" is selected. That is, it is sufficient to simply compare the first numerical values of the range designation and select the closer one. Also, if they are the same, the one with the smaller numerical value is selected.

In step S206, the position information stored in the new position information area 45 and the comment content 42 are paired to generate comment information, which is written in the new document comment file 54. At this time, the data format of the new document comment file is the comment file format as shown in FIG. The file name of the new document comment file 54 has the file name of the new document file 53 with a specific extension. For example, the new document file name is do
If it is c2, the name of the new document comment file is d
oc2. and the like. This doc
2. If the comment file does not exist, a new file is created, and if it already exists, it can be added to it.

Next, in step S207, it is determined whether or not the transfer processing has been executed for all the comment information of the old document comment file 52. If unprocessed comment information remains, the process returns to step S201 to repeat the above process. If the processing has been completed for all comment information, this processing ends.

On the other hand, if no candidate is found in step S204, step S208 proceeds and the comment information attached to the old document at that time is registered in the dropout comment file 55. As for the file name of the dropout comment file 55, if the old document file name is doc1 and the new document file name is doc2, a specific extension is added to the names of the old document and the new document, such as doc1-doc2, dropout. It is easy to understand if you do the same.

When registering in the dropout comment file 55, the dropout file 55
If does not exist, create a new file by the above method and register it. When the dropout file 55 already exists, it is added to the file as it is. The dropout comment file 55 is registered in the same format as that shown in FIG. 4, for example. Then, the process proceeds to step S207.

7, 8 and 9, a new document file 53, a new document comment file 54, which is the result of this processing,
The contents of the dropout comment file 55 are shown. The contents of the new document file 53 are the contents of the old document file 51 shown in FIG. 3 changed from "Kakikukeko" to "Yayuyo". At this time, in the new document comment file 54 generated by the comment transfer processing described above, the comment information that has been successfully searched for in the equivalent portion in step S203 is registered. The position information, that is, the content of the document element <place> is changed to the new position information (11th to 15th characters). In the dropout comment file 55, comment information that fails to search for the equivalent part in step S203 is registered. This directly registers the comment information in the old document comment file.

As described above, according to the document processing apparatus of the first embodiment, when the comment is automatically transferred from the old document to the new document, the corresponding commenting position is set in the new document. If the comment is not found, the comment is saved in another file, so that the comment in the old document can be prevented from being accidentally deleted.

<Embodiment 2> In the process of transferring a comment from an old document to a new document, as a method of detecting a comment (dropout comment) for which a comment addition position was desired to be detected, both comments for the new and old documents are detected. It is also possible to detect dropout comments depending on the file. In the second embodiment, one example will be described.

The schematic configuration of the document processing apparatus according to the second embodiment is similar to that of FIG. 1 of the first embodiment, and the description thereof will be omitted here. The configurations of the document file and the comment file are also the same as those in the first embodiment, and the description thereof will be omitted.

Next, the comment transfer processing by the document processing apparatus according to the second embodiment will be described with reference to FIGS. 10 and 11. FIG. 10 is a flowchart showing the procedure of the comment transfer processing by the document processing apparatus according to the second embodiment.

Incidentally, steps S1001 to S10
03 is step S201 to step S20 of the first embodiment.
Since it is the same as that of No. 3, detailed description will be omitted. Further, steps S1005 to S1007 are also the same as steps S205 to S207 of the first embodiment described above, and thus detailed description thereof will be omitted.

In step S1004, step S
As a result of the search in 1003, it is determined whether one or more candidates are stored in the candidate area 44, and if one or more candidates are stored, the process proceeds to step S1005.
If no candidate is found, the process proceeds to step S1007 and the process for the next comment is executed.

As described above, when the new document comment file 54 is generated, no processing is performed on the comment information for which the search for the equivalent part has failed.

Next, the comment file 54 for the new document and the comment file 52 for the old document obtained by the processing of FIG.
From the difference, the procedure for creating the dropout comment file 55 will be described with reference to the flowchart of FIG. FIG. 11 is a flowchart illustrating a procedure for generating a dropout comment file by the document processing apparatus according to the second embodiment.

First, in step S1101, <content> and <// in the comment file 52 for the old document.
The character string (contents of the comment) surrounded by content> is read and stored in the character string area 43. In this process,
Although the same storage location as the area used in the processing according to the flowchart of FIG. 10 is used, it may be another location. Then, in step S1102, <content> and </ cont> in the comment file 54 for the new document
character string area 43 among the character strings surrounded by ent>
Search for the equivalent. In step S1103, it is determined whether or not there is the same character string in the search in step S1102. If it is determined that the same character string exists, step S1103 is performed.
Proceed to 1105.

On the other hand, if it is determined in step S1103 that the same character string does not exist, the flow advances to step S1104 to add the comment information (corresponding to <co in the comment file for the old document to the dropout comment file 55).
character string from mmment> to </ comment>)
Write. Then, in step S1105, it is determined whether or not the processing has been completed for all the comment information of the old document comment file. If there is unprocessed comment information, the processing returns to step S1101 and the above-described processing is repeated. If all comment files have been processed, this process ends.

As described above, according to the document processing apparatus of the second embodiment, the comment replacement process and the dropout comment detection process can be separated into two.
Easy to use.

<Third Embodiment> A third embodiment will be described below.

In the third embodiment, when a portion having the same meaning as the old document cannot be detected from the new document, it is clearly indicated that the corresponding comment (there may be a plurality) at that time has failed to be replaced. Together with the code to be stored in the comment file for the new document.

In the third embodiment, the method of detecting a portion having the same meaning as the old document from the new document and the method of adding a comment to the original document are the same as those in the first embodiment. The structure of the comment file is also the same as that in the first embodiment.

The document processing apparatus of the third embodiment will be described below with reference to the drawings.

FIG. 12 is a block diagram showing the schematic arrangement of the document processing apparatus according to the third embodiment. The same configurations as those in FIG. 1 in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted here. The work memory 4 has a dropout comment area 46. The dropout comment area 46 is an area for temporarily storing dropout comment information. Further, no dropout comment file exists in the file memory 5.

Next, the operation of the comment transfer processing by the document processing apparatus of the third embodiment having the above configuration will be described. FIG. 13 is a flowchart illustrating the procedure of the comment transfer process performed by the document processing apparatus according to the third embodiment.

In the figure, steps S1301 to S
Since step 1307 is the same as step S201 to step S207 in FIG. 2, description thereof will be omitted, and different steps will be described.

If it is determined in step S1304 that there are no candidates, the flow advances to step S1308 to write the comment information in the dropout comment area 46 of the working memory 4. Then, the process proceeds to step S1307. When it is determined in step S1307 that the comment transfer processing has been completed for all the comment information stored in the old document comment file 52, the process proceeds to step S1309. In step S1309, the contents of the dropout comment are added to the end of the new document comment file 54 with the character strings <dropout> and <// dr.
surrounded by opout> and added.

FIG. 14 is a diagram showing the contents of the new document comment file 54 as a result of executing the comment transfer processing by the document processing apparatus of the third embodiment. This is Example 1
Similar to the one described above, an example of changing "Kakikukeko", which is a part of the contents, to "Yayuyo" for the old document file 51 and the old document comment file 52 shown in FIG. Is. At this time, the new document file 53 becomes as shown in FIG.

In the above description, the dropout comments are collectively placed at the end of the new document comment file, but it goes without saying that they may be placed at the beginning of the new document comment file. Further, instead of collectively arranging them at the beginning or the end, they may be scattered so that they can be distinguished as dropout comments. For example, in step S1308 of FIG. 13, the character string <dropout>
Each dropout comment information is written in the new document comment file 54 by enclosing it with </ dropout>. In this case, the process of step S1309 is unnecessary. By doing this, the information of the dropout comment is scattered in the comment file for the new document, and the character strings <dropout> and </ dropout
It will be saved surrounded by>. Alternatively, FIG.
As shown in, the value of the position information of the comment file for the new document is assigned with an absolutely impossible numerical value such as "0, 0" or "-1. You may specify that there is. This will give you the strings <dropout> and </ dropou
Scattered dropout comments can be distinguished without being surrounded by t>. The method of the second embodiment may be used as the dropout comment detection method.

In the third embodiment, since the comment replacement succeeded and the comment replacement failed are stored in the same file, it is possible to avoid the situation in which only one of them is lost. This has the effect of making it easier to manage.

In each of the above embodiments, the exact matching of the character strings is used for detecting the equivalent portion of the old document and the new document, but the invention is not limited to this. For example, a method may be used in which the degree of similarity is calculated from the number of matching characters in the comment-added portion, and when the degree of similarity is equal to or more than a predetermined value, the similarity is determined.

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

[0059]

As described above, according to the comment assigning method and the document processing apparatus of the present invention, when a comment is automatically transferred between documents, the comment cannot be transferred. By separately storing the information, it is possible to prevent the comments from being accidentally lost when the comments are transferred.
