Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hyperlink apparatus for retrieving necessary information from a plurality of files connected by link information, and more particularly to an automatic update apparatus for a hyperlink apparatus for automatically updating link information. The present invention relates to a method for automatically updating a hyperlink device.

[0002]

2. Description of the Related Art In a hyperlink apparatus which is a kind of information retrieval apparatus, a plurality of files 1 to be searched are generally registered in a database as shown in FIG. One set of information is written in each file 1. A large number of keywords are set in the information stored in each file 1, and the keywords include file names of other files 1 in which information related to the own keyword is written, and related information of the file. The link information 2 such as the address at which is written is added.

Therefore, when an operator (searcher) of the hyperlink device searches each file in the database of the hyperlink device for a keyword of target information, a file in which information on the keyword is stored is searched. Is displayed. If the information stored in this file is not the expected information, for example,
When a key is operated on the skip key, information relating to the keyword in another file 1 specified by the link information 2 attached to the keyword is automatically read and displayed. As described above, by sequentially searching the related file 1 by the link information 2, the operator can search for the target information in a short time.

[0004]

However, the following problems still need to be solved in the hyperlink apparatus in which the target information is sequentially searched by the above-described procedure. That is, the link information 2 attached to the keyword in each file 1 only includes designation information such as the file name of the file 1 to be searched next and the number of lines of the file. Therefore, once the control of the search is shifted to the next file specified by the link information 2, it does not return to the original file.

In a hyperlink device having such a configuration, when a large number of files are registered in a database,
Naturally, each file may be specified by link information described in a plurality of files.

Further, among a large number of files registered in the database, the file name has been changed, the link information 2 indicating the designated destination (reference destination) has been changed, and the file has become unnecessary. The file itself may be deleted.

As described above, when the file information is changed, it is necessary to change the contents of the link information 2 of another file having the specified file as a designated destination (reference destination) or to delete the link information 2.

However, as described above, since the link information 2 of each file 1 is information for specifying the designated file 1 (reference destination), the file to be changed is designated or the link information is written. Unable to identify embedded file.

Therefore, the engineer who first designed and constructed the hyperlink device remembers the file in which the link information designating the file to be changed is written based on the past memory, and The link information needs to be corrected.

However, as described above, if a large number of files are registered in the database, even if the engineer is familiar with this hyperlink device,
It is impossible to grasp all link information to be changed.

Therefore, in such a case, it is necessary to rebuild the hyperlink device from the beginning.
As a practical matter, it has not been possible to change the link information for large hyperlink devices.

The present invention has been made in view of such circumstances, and by storing and holding a file including link information designating itself for each file, even if the file information is changed. Automatic update of the hyperlink device that automatically updates the link information of each related file, easily changes the file information, always sets the optimal link information, and can reliably search for the necessary information. And a method for automatically updating a hyperlink device.

[0013]

According to the present invention, a plurality of files in which link information for designating another file in which information related to the self is described are written in a self file, and necessary information is stored. Is applied to a hyperlink device that sequentially searches each file using this link information.

Then, in order to solve the above-mentioned problem,
In the automatic updating device of the hyperlink device according to the present invention, for each file, a link information management table for storing each file of the designated source when the file is specified by the link information, A change management table for temporarily storing change information of file information;
Using the change information stored in this change management table,
Link information updating means for reading a specified source file from the link information management table and updating the link information of the specified source file based on the change information; and link information management based on the change information stored in the change management table File information changing means for changing the information of the table and the designated file.

In the automatic updating method for a hyperlink device according to the present invention, a link information management table for storing each file of a designated source when the file itself is designated by link information is created for each file. The change information of the file information of each file input from the file is temporarily stored and held in the change management table, and according to the change information stored in the change management table, the designated source file is read from the link information management table, and The link information of the designated source file is updated based on the change information, and thereafter, the link information management table and the information of the specified file are changed based on the change information stored in the change management table.

In the automatic updating device and the automatic updating method for the hyperlink device configured as described above, the link information management table contains, for each file, each of the designation sources when the self is designated by the link information. File is stored. Therefore, when the file name or the link information of an arbitrary file is changed, all files whose link information other than the own file specifies the own file can be easily specified using the link information management table.

Therefore, the link information designating the self of the specified file is changed (updated) based on the change information.
do it. For example, when the change information is a file name change, the file name of the link information may be changed to the file name after the change. Therefore, only by changing the file information, the operator automatically updates the necessary link information of another file.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is a block diagram showing a schematic configuration of a hyperlink device in which an automatic updating device adopting an automatic updating method according to a first embodiment of the present invention is incorporated. This hyperlink device is constituted by a kind of information processing device such as a computer.

In the hyperlink device, a database 12 in which a plurality of files 11 to be searched are registered.
, A change management table 13, a link information management table 14, and the input operation unit 1 configured by, for example, a keyboard or the like.
5 and a search result output unit 16 composed of, for example, a CRT display device.

Further, in this hyperlink device,
File search unit 17, change information input unit 18, link information management unit 19, link information update unit 2 formed as a program module on the application program
0, a file information changing unit 21 and the like.

A plurality of files 11 are registered in the database 12 as shown in FIG. Each file 11 is assigned a file name 22.
A plurality of keywords related to the described information are described in the information described (stored) in each file 11, and the keywords include information related to the own file in another file 11. Link information 23 such as a file name (link destination file name) and an address where related information in this file is written are added.

In the database 12, as shown, a file 1 in which a plurality of pieces of link information 23 are written is stored.
1 and the file 11 in which the link information 23 is not written at all.

In the link information management table 14,
As shown in FIG. 3, a file name table 24 storing the file names 22 of the files 11 registered in the database 12, and a link for designating the file 11 for each file name 22 of the file name table 24. A designation source file name memory 25 for storing the file name 22 of the file 11 in which the information 23 is written is formed.

Therefore, there are a case where a plurality of file names 22 are stored in the designation source file name memory 25 and a case where only one file name 22 is stored. Further, when the self file 11 is not specified at all from other files, the file name 22 is not set in the specification source file name memory 25.

Further, in the change management table 13, file change information 26 specifying the file name 22 input via the input operation unit 15 is temporarily stored. In this embodiment, the case where the own file name 22 is changed is shown, and the changed file name 22a is stored as the file change information 26.

When the link information 23 written in the self-file 11 is changed as well as the file name 22a, the changed link information 23 is written as the file change information 26.

In the hyperlink device having such a configuration, when an operator (searcher) inputs a keyword of desired information through the input operation unit 15, the file search unit 17 is activated and the input keyword is input. Search for each file 11 in the database 12 and display the storage contents of the file 11 in which information on the corresponding keyword is stored on the search result output unit 16 comprising a CRT display device. If the operator (searcher) operates the skip key, for example, when the information stored in the searched file 11 is not the expected information, the operator is automatically specified by the link information 23 attached to the keyword. The information on the corresponding keyword in another file 11 is read and displayed.

Next, each file 11 in the hyperlink device that performs such a basic file search process will be described.
Will be described with reference to the flowcharts of FIGS. 5 and 6.

First, in S (step) 1 in FIG. 5, the link information management unit 19 is activated to start link information management processing. And the link information management table 1
4 is performed. Specifically, the file name 22 of each file 11 of the database 12 is written in the file name table 24 of the link information management table 14. When the process of writing all the file names 22 to the file name table 24 is completed, the specification corresponding to the file name 22 of the specification destination file 11 indicated by the link information 23 written in each file 11 of the database 12 is next performed. The own file name 22 is written in the original file name memory 25.

That is, for the file 11 of the file name 22 written in the file name table 24, the file name 22 of the file 11 of the specification source in which the link information 23 for specifying the file name 22 of the file 11 is described. The data is written to the designated source file name memory 25.

When the setting process of the file name 22 of the file 11 in which all the link information 23 written in each file 11 of the database 12 is described is completed in the corresponding designation source file name memory 25 by the above-described method. ,
The process of creating the link information management table 14 ends.

The link information management table 14 may be created or newly set when a new hyperlink device is constructed or when a new file 11 is added to the database 12. .

With each file name 22 set in the link information management table 14, the operator operates the input operation unit 15.
When a file change operation of the file 11 registered in the database 12 is started via the program (S3), the change information input unit 18 is activated to check the type of the file change. Specifically, the file change operation includes file copy S4a, file move S4b, and file name change S4c. Although not shown, the link information 23 in the file 11 may be changed or deleted.

The change information input unit 18 writes the file name 22 and the file change information 26 into the change management table 13 (S5). Specifically, for example, in the case of file name change, the file name 22 before change and the file name 2 after change
2a is written in the change management table 13.

In S6, if the file 11 to be changed still exists in the database 12, the process returns to S4a to S4c, where the type of file change is checked, and the file change information 2 is checked.
6 is additionally written into the change management table 13.

In S6, if the file 11 to be changed does not exist in the database 12, the file change operation ends (S7). Next, the process proceeds to S8 of FIG. 6, and the automatic change processing of the link information 13 is started. Specifically, it is checked whether or not the unprocessed file name 22 and the file change information 26 exist in the change management table 13 (S9). If it exists, the unprocessed file name 22 is read from the change management table 13 and the file name 22 is searched for the file name table 24 of the link information management table 14.
Then, the designated source file name memory 25 corresponding to the searched file name 22 is checked (S10).

The specified source file name memory 25
If the file name 22 is set in the file 11, it is determined that the link information 23 written in the file 11 corresponding to the file name 22 needs to be changed. Then, the link information updating unit 20 is activated and updates (changes) the link information 23 for specifying the file 11 changed this time so as to correctly specify the file 11 (S11). For example, in the case of a file name change, the file name 22 before the change written in the link information 23 is rewritten to the file name 22a after the change.

When a plurality of file names 22 are set in the specified source file name memory 25, the link information 23 of the corresponding file 11 is updated (changed) for each set file name 22. I do.

When the update (change) processing of the link information is completed, the file information change section 21 is activated and updates the link information management table 14. That is, in the case of a file name change, the corresponding file name 22 in the file name table 24 is rewritten to the changed file name 22a (S12). At the same time, the file name 22 of the file 11 in the database 12 is changed to the changed file name 22a.

In step S10, if the file name 22 is not set in the specified source file name memory 25 corresponding to the searched file name 22, the link information 23 for specifying the file 11 that has been changed this time. Does not exist, the link information management table 14 is immediately updated. That is, when the file name is changed, the corresponding file name 22 in the file name memory table 24 is rewritten to the changed file name 22a (S13).

The file change information 26 temporarily stored in the change management table 13 indicates that the link information 23 has been deleted,
If you want to add or change the link destination,
The deletion and addition of each file name 22 set in each specified source file name memory 25 of the link information management table 14 are performed by the method described in 2.

Then, returning to S9, the change management table 1
It is checked whether or not the file name 22 and the file change information 26 for which the change processing has not been processed exist in the file 3.
Link information 23 corresponding to the unprocessed file name 22
Executes the update (change) processing of.

If there is no unprocessed file name 22 and file change information 26 in the change management table 13 in S9, the current automatic change processing of the link information 23 ends (S14).

In the hyperlink device configured as described above, when the hyperlink device is newly constructed, when the file 11 is newly registered in the database 12, or when the registered file 11 is When deleting, a link information management table 14 is created.

In the link information management table 14,
For each file name 22 of each file 11 stored in the file name table 24, the file name of each file 11 of the designation source when the self is designated by the link information 26 in the designation source file name memory 25 corresponding to the self 22 are stored.

Therefore, when the file information such as the file name 22 and the link information 23 in an arbitrary file 11 is changed, the link information 23 is used for all the files specifying the own file 11 by using the link information management table 14. 11 can be easily searched.

Therefore, the link information 23 designating the self of the searched file 11 may be changed (updated) based on the file change information 26. For example, when the file change information 26 is a change of the file name 22, the file name 22 of the link information 23 is changed to the file name 22 after the change.
It may be changed to a.

Therefore, the operator only changes the file information such as the file name 22 and the link information 23 by designating the file 11 via the input operation unit 15, and automatically changes the file information based on the file change information 26. The link information 26 designating the self of the other file 11 is automatically updated.

Therefore, the file information can be easily changed when necessary, and the optimal link information 23 is always set.
As a result, necessary information can be reliably retrieved using this hyperlink device.

(Second Embodiment) The present invention is not limited to the first embodiment. In the first embodiment, as shown in the flowcharts of FIGS. 5 and 6, the process of creating the link information management table 14 is performed when the hyperlink device is newly constructed or when a new file is stored in the database 12. 11 is executed when the file 11 is registered or when the file 11 registered in the database 12 is deleted.
Then, after that, when a plurality of file change operations are performed on the plurality of files 11 and the plurality of file change information 26 is stored in the change management table 13, the link information of the operator via the input operation unit 15 is displayed. The update processing of the link information 26 was performed based on the update instruction.

On the other hand, in the second embodiment,
When the hyperlink device is newly constructed, the process of creating the link information management table 14 is performed. And
Each time one file 11 is newly registered in the database 12, one registered file 11 is deleted, or one registered file 11 is changed, the database 12 related to the file 11 is changed.
Link information 23 of each other file 11 registered in
Automatically update.

FIG. 7 is a flowchart showing an automatic update process of the link information 23 of each of the other files 11 when the above-described new registration, deletion, or change of one file 11 occurs.

When an instruction for new registration, deletion, or change of one file 11 is input from the operator via the input operation unit 15, the link information management unit 19 starts link information management in Q1, and performs an input operation. The contents of the instruction from the unit 15 are determined, and if there is a new registration and deletion of the file 11 and a change of the link information (change of the link destination, deletion of the link information, addition of the link information), according to the instruction. Correction processing of the setting contents of the link information management table 14 is performed (Q
2).

Next, the contents of the instruction from the input operation unit 15 are the copy Q3a of the file 11 and the movement Q3 of the file 11.
b, in the case of the file name change Q3c, the file change information 26 of the file 11 is set in the change management table 13 as in the flow chart shown in FIG. 5 of the first embodiment (Q4).

The designated source file name memory 25 corresponding to the file 11 in the link information management table 14
The link information 23 of the file 11 having the file name 22 set in the
4 is replaced with the changed file name 22a in the file name table 24 (Q5, Q6, Q
7).

When a plurality of file names 22 are set in the specified source file name memory 25, the link information 23 of the corresponding file 11 is updated (changed) for each set file name 22. I do.

In Q5, the file name 2 retrieved
In the case where the file name 22 is not set in the designation source file name memory 25 corresponding to 2, the link information 23 for specifying the file 11 changed this time does not exist.
Immediately update the link information management table 14 (Q
8).

Even with the hyperlink device of the second embodiment configured as described above, the operator can newly register one file 11 in the database 12 or register one registered file 11 in the database 12. When deleting or changing one registered file 11, at that time. The link information 26 of the other file 11 automatically registered in the database 12 is updated (changed) to a correct value.
