Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information management device and method for managing link information for Web pages on the Internet.

[0002]

2. Description of the Related Art In recent years, networks have become widespread, and an increasing number of companies and the like are constructing an intranet for connecting computer devices in a company to each other via a network. In many cases, the intranet is connected to the Internet, and information on the Internet can be browsed from within the company.

On the other hand, on the Internet, for example, HT
Various information is disclosed by Web pages described based on ML (Hyper Text Markup Language). The location of these web pages on the Internet is UR
It is described in a format called L (Uniform Resource Locator). URLs of other web pages in the web page,
By writing in a prescribed format, U
It is possible to access another web page in which the RL is described.

As described above, the U of another Web page is
Writing the RL in an accessible format is called "attaching a link", and the description of such URL itself is
It is called a "link". A web page corresponding to the cover of one or a plurality of web pages is called a home page (hereinafter abbreviated as HP), and a series of web pages having HP as a cover constitutes a website.

In such an environment, a Web server on the Internet is connected to a server on the intranet in the company.
Provide a link collection that summarizes link information for pages,
It will be published to the intranet. This link collection is provided as a Web page in the intranet, similar to the Web page on the Internet. By using such a link collection, it becomes easy to access from inside the company a Web page on the Internet where useful information is disclosed.

[0006]

Conventionally, such a We
When creating the b-page link collection, for example, a website of a newspaper company, a government agency, or an individual was sequentially accessed, and from there, it was determined whether or not the information should be published in the link collection. Furthermore, when posting the website in the link collection, it was determined whether the link should be posted or not, and the URL should be displayed without the link.

For example, depending on the website, it may be possible to freely attach the link, or it may be necessary to notify the administrator of the website in advance that the link is to be attached. Also, there may be a website that does not allow any links. In such a case, if a link is arbitrarily attached to a website that does not permit the attachment of the link, a complaint will come from the linked website. On the other hand, if the link is not attached to a website where the link can be freely attached, the viewer will not use the website. Further, there is a website that becomes link-free after the link is affixed once the administrator of the website gives permission. In this case, the information before the link permission is not changed.

Conventionally, there has been a problem that these judgments are made manually for each Web site published in the link collection. In particular, there has been a problem that when the link information posted in the link collection increases, the burden on the creator of the link collection becomes very heavy.

Further, the creation of a Web page is generally performed manually by application software designed exclusively for creating a Web page, a text editor, or the like. Therefore, the order of the link information posted in the link collection is decided depending on the taste of the link collection creator, and it is likely that it will be difficult for general viewers to see and use. There was a problem.

Therefore, an object of the present invention is to provide an information management apparatus and method for easily managing link information when creating a link collection of Web pages.

Another object of the present invention is to provide an information management device and method for creating a link collection with a structure that is not influenced by the taste of the link collection creator.

[0012]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a plurality of Webs on the Internet.
In an information management device that manages link information for creating a link collection that provides a linking means to each page, management that manages the location information of the link destination and also manages the display method of the link destination for each link destination An information management device having means, wherein the location information of the link destination is described based on the display method of the link destination to generate a link collection in which the location information of the plurality of link destinations is generated. .

Further, the present invention is an information management method for managing link information for creating a link collection for providing a linking means to each of a plurality of Web pages on the Internet, and managing the location information of the link destination. ,
Manage the display method of the link destination for each link destination, describe the location information of the link destination based on the display method of the link destination, and generate the link collection in which the location information of multiple link destinations is posted. Is an information management method characterized by:

As described above, the present invention manages the link destination location information, manages the link destination display method for each link destination, and describes the link destination location information based on the link destination display method. Since a link collection in which the location information of multiple link destinations is posted is generated, each time the link collection is updated, the description of the link destination location information according to the display method of the link destination is created. There is no need to do it.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 schematically shows a configuration of an example of a link information management system according to an embodiment of the present invention. Intranet 1 is an organization,
For example, it is a network system provided in-house in a company. Intranet 1 is firewall 2
Is connected to the Internet 3 outside the company. That is, the communication between the intranet 1 and the internet 3 is
All are done through the firewall 2.

For the intranet 1, an in-house HP server 10 and a plurality of personal computer devices 17, 1 are provided.
7, ... are connected. The personal computer device 17 is described as a personal PC 17 in FIG. The personal computer devices 17, 17, ...
Each is equipped with browser software capable of browsing websites.

This browser software displays a web page constituting a web site in a layout specified based on, for example, the description in HTML, and when a URL is described in a predetermined format in the web page. By specifying the URL in advance, the Web page indicated by the URL can be accessed.

The in-house HP server 10 is a server for providing a website on the intranet 1 to the in-house. In this in-house HP server 10, a link collection for in-house is generated by this link information management system, and is published to the intranet 1. The in-house HP server 10 includes a link destination information database 11, a link destination pre-update information database 12, and a link information database 13 as databases used to generate the link collection.

The link destination information database 11 stores information about the linked websites and web pages published in the link collection. For example, the linked web
Information such as the form of updating the Web page on the site and the handling of links is stored in the link destination information database 11.

The pre-update information database 12 for each link destination holds Web page data collected during the previous patrol of the link destination by this link information management system. W of the link destination by this link information management system
By comparing the information of the actual access to the eb page with the information of the corresponding web page stored in the pre-update information database 12 for each link destination, it is determined whether or not the web page is updated and the update content.

The link information database 13 is an internal HP
The link information disclosed to the intranet 1 by the server 10 is stored. Link information database 13
In the link information, link information is stored in association with each use, such as a genre-based link collection 14, an information source-based link collection 15, and a date-based link collection 16.

Although not shown in FIG. 1, in practice, a server that manages the intranet 1 itself, a mail server that manages exchange of electronic mail with the intranet 1 and the Internet 3, business in-house, etc. The database used for the database and the database server that manages the database are the intranet 1
Is further connected to. A server equivalent to a commonly used server device can be applied to each server including the in-house HP server 10, and thus detailed description thereof is omitted here.

A large number of servers having a large number of Web pages are connected to the Internet 3. In the example of FIG. 1, newspaper company H, which has a website provided by newspaper company A,
The P server 31, the government office HP server 32 where the website of the B office is provided, and the personal HP server 33 of the C individual are shown on behalf of them.

For example, the newspaper company HP server 31 uses the HP (home page) by newspaper company A as the cover page, and newspaper company H
One or a plurality of Web pages on the P server 31 are linked from the HP to build a Web site of A newspaper company. A person who wants to browse the website of a newspaper company,
The HP on the newspaper company HP server 31 can be accessed first, and each Web page can be accessed from there. Further, if the URL is known in advance, it is possible to directly access each website constituting the website. This is the government HP server 32 or the personal HP server 33.
The same is true for.

The firewall 2 is the Internet 3
To the proxy address of the intranet 1. That is, the firewall 2 is a server serving as a window for the Internet 3 of the intranet 1. That is, from the Internet 3 to the intranet 1
.. and the in-house HP server 10 are accessed from the Internet 3 to the firewall 2 and then from the firewall 2 to each device in the intranet 1. It

Inversely, all access from the intranet 1 to the Internet 3 is made through the firewall 2. At this time, the Web page on the Internet 3 accessed through the firewall 2 is cached in the firewall 2. Since the access to the Web page cached in the firewall 2 is made not to the Web page on the Internet 3 but to the Web page cached in the firewall 2, the increase of the traffic of the Internet 3 is prevented and the Web page is not accessed. You can access the page at high speed.

A reference count information database 20 is connected to the firewall 2. As described above, since the access from the intranet 1 to the Internet 3 is made through the firewall 2, the firewall 2 accesses the W that is accessed from the intranet 1.
It is possible to measure the reference count for each eb page.
The measured reference count for each Web page is stored in the reference count information database 20.

As is well known, in the Internet 3, TCP / IP (Transmission Control Protocol) is used.
ol / Internet Protocol) is used as a protocol, and addresses of computer devices connected to the Internet 3 are represented by IP addresses. This IP
The address is the current IPv4 (Internet Protocol versi
On 4), it is represented by a list of 32-bit numbers, which makes it very difficult for humans to get used to. Therefore,
An IP address is converted by a DNS (Domain Name System) server into address information that can be easily identified by humans.

As described above, all communication between the intranet 1 and the Internet 3 is performed by the firewall 2.
Firewall 2 is accessed via the intranet 1.
You have all the IP address information for your site. Therefore, the firewall 2 can have a DNS server function.

The personal computer device 17 has the same configuration as a general computer device and has a GUI (G
raphical User Interface) is applied, and it is possible for the user to operate intuitively by using a pointing device such as a mouse. For example, by indicating a button or the like that is arranged and displayed on the screen on the basis of the coordinate information output from the pointing device and performing a predetermined operation on the pointing device, the function assigned to the displayed button Can be executed.
Hereinafter, a series of processes for displaying a button using this pointing device will be referred to as “operating a button”, “pressing a button”, and the like. Of course, not only the pointing device but also other input means such as a keyboard can be used to execute a predetermined function.

Next, the operation of the link information management system according to the embodiment of the present invention having the above-mentioned configuration will be schematically described with reference to the flowchart of FIG. Here, it is assumed that the link collection created based on this link information management system already exists on the in-house HP server 10 and is being operated. The link collection is described in HTML, for example, and is placed on the in-house HP server 10 as an HTML file.

First, in step S1, when the link information management system is started up, the link destination information database 11 is referred to, and the link destinations listed in the link collection were last accessed by this link information management system. Last access date and the web set as the link destination
The page update dates and times are compared, and it is determined whether the current date and time has passed the update date and time from the last access date and has passed the date and time. Based on the result of this determination, the information of the website determined to have exceeded the update date and time is automatically collected. Details of the link destination information database 11 will be described later.

Next, in step S2, the collected Web
Web with information added / not posted on links, decision of genre selection, etc. based on additional information on page
Done for each of the pages. This step S2
Processing is performed by a GUI (Graphical Use), an example of which will be described later.
r Interface) and is manually performed by the operator of this link information management system.

Then, in step S3, step S
The information determined in 2 is registered in the link information database 13, and the content is reflected. An HTML file for displaying the link collection is automatically generated based on the contents registered in the link information database 13 and is published to the intranet 1 in the in-house HP server 10. The details of the link information database 13 will be described later.

Next, the processing in each part of the flowchart of FIG. 2 will be described more specifically. FIG. 3 shows an example of the configuration of the link destination information database 11. The last access date described above corresponds to the item “last access date”. Also,
The update date and time described above corresponds to the item “update date and time”. The item “update date and time” indicates how often and for how long the Web page is updated. This item "Update date and time"
As the information described in (1), for example, the creator of the link collection or the administrator inputs the result of the actual survey on the Web page.

The item "link handling" indicates how the management source of the web page handles links to the web page from others. "Unlinkable" means that a direct link from a web page or the like is not permitted.
"Linkable" indicates that a direct link to the web page is permitted, and "requires permission each time" indicates, for example, a direct link to the administrator of the web page each time the web page is updated. Indicates that it is necessary to inquire whether or not

A direct link means, for example, in HTML, an anchor tag (<A HREF = "URL") indicating a link.
> ... </A>), the URL to the URL
Direct access from the eb page is possible.
On the browser software, by pointing the direct link by a predetermined operation using a pointing device such as a mouse, the web page linked by the direct link is automatically accessed.

The contents shown in the item "link handling" are reflected in the item "URL". In the example of FIG. 3,
The URL of the Web page that has already been licensed as “linkable” or “necessary permission each time” is underlined to indicate that a direct link is possible. On the other hand, the URL of the web page that is "unlinkable" is not underlined. In such a link collection, such a link to a Web page that is "unlinkable" is only described as a URL, and a direct link is not described.

The item "update style" indicates which of the prepared styles the update style of the Web page belongs to. Web page update styles can be classified into several types. In this embodiment,
Web page update styles are categorized into three types: "By unit, add from top", "Add from top", and "Full update".

FIG. 4 shows an example of updating a Web page when the update style is "By unit, add from top". Figure 4A
Indicates the display state of the web page before the web page is updated. Note that the unit corresponds to the classified information type when, for example, information on a Web page is posted classified according to the information type. In the example of FIG.
The units "Politics" and "Economy" are classified as units.

Initially, it is assumed that information A11, A12 and A13 are included in the unit "politics" and information A21 and A22 are included in the unit "Economy" on the Web page as shown in FIG. 4A. After this Web page is updated, some information is changed from FIG. 4A, and information A13 and A11 is added to the unit “politics” as shown in the display state of FIG. 4B.
And A12 have information A23 and A2 in the unit "economy"
4 was published.

In this case, the information added and deleted on the Web page before and after the update can be obtained by taking the difference between the information before the update and the information after the update. In this example, the added information is as shown in FIG. 4C:
In the unit “politics”, the information A13 has different contents from the information A13 before the update, and in the unit “economy”, the information A23 and A24. These additional information are shown in Figure 4.
As shown in B, it is additionally displayed from the top for the information existing before the update. Further, as shown in FIG. 4D, the information A21 and A22 and the information A13 before updating are deleted and disappear from the Web page.
In this way, in the update style “By unit, add from above”, additional information is additionally displayed from above for each unit.

This update style "By unit, add from top"
Is an update style often found on Web pages of websites by newspaper companies.

FIG. 5 shows an example of updating a Web page when the update style is "add from top". FIG. 5A shows We
The display state of the web page before page b is updated is shown. In the example of FIG. 5, information is collected and displayed for each date.

Before updating the Web page, information of December 5 and December 6 is displayed as shown in FIG. 5A. When the Web page is updated on the next day, information on December 6th and 7th is displayed, as shown in an example in FIG. 5B. That is, the web before and after the update
12 is shown in FIG. 5C by taking the difference between the display contents of the pages.
The information B31 and B32 of the month 7 are added, the information B21 and B22 of the December 5 shown in FIG. 5D are deleted, and are deleted from the Web page. Added on Dec 7
As shown in FIG. 5B, the date information B31 and B32 are additionally displayed from above on the information B11 and B12 of December 6 which continues before the update.

This update style "add from top" is an update style often found on Web pages of Web sites by government offices, for example.

FIG. 6 shows an example of updating a Web page when the update style is "full update". 6A and FIG.
B shows the display states of the web page before and after the web page is updated, respectively. In this case, the Web
Since the information displayed on the web page is renewed by the page update, if the difference between the display contents before and after the web page update is taken, the information before the web page update is deleted as it is and the information disappeared from the web page. (Fig. 6
D), the updated information is directly used as additional information (FIG. 6).
C).

This update style "full update" is an update style often found on Web pages of websites operated by individuals, for example.

Returning to the explanation of FIG. 3, the item "disappearance of information"
Indicates the timing at which the information displayed on the Web page disappears. Here, even if the information displayed on the Web page disappears on the display of the Web page due to the update of the Web page, the information itself is not deleted and exists on the server where the Web page is placed. There is.

For example, in a Web page in which headings of information are displayed, it is considered that a link is attached from each heading to a Web page in which details of information are written. In this case, the Web where the headline is displayed
Even if the headline of certain information is deleted on the page, the Web page itself linked from the headline may not be deleted. In this case, it is possible to continue linking the detailed information to the web page even after updating the web page in which the headline is displayed.

This item "disappearance of information" is, for example, the W
The timing at which the eb page itself is deleted and the link to the web page is disabled is shown. The information indicated in the item “Disappearance of information” is actually investigated and input for each of the Web pages registered in the link destination information database 11 by the operator of the link information management system, for example.

The item "genre setting" indicates the genre of the Web page determined from the content of the Web page. The determination of the genre is, for example, actually conducted by the operator of the link information management system for each Web page registered in the link destination information database 11 and input.

The item “priority order” is automatically set based on the number of references for each Web page stored in the reference count database 20 connected to the firewall 2. Based on the value shown in this item "priority order", the order in which the links appear in the link collection is determined.

By the step S1 in the flow chart of FIG. 2 described above, this link destination information database 11
Is referred to, and the date and time indicated in the item “last access date and time” for each Web page is compared with the current date and time.
As a result of comparison, if it is determined that the current date and time exceeds the period, date and time, and update timing indicated in the item “update date and time” with respect to the date and time indicated in the item “last access date and time”, the item “URL Based on the URL shown in
Information on page b is automatically collected.

Collection of Web page information is performed as follows, for example. The pre-update information of each Web page is held in the pre-update information database 12 for each link destination.

For each information source, the information on the last access date of the Web page is held as pre-update information for each link destination in a template in a text data format or the like. When a Web page is accessed for collecting information, the template held in the pre-update information database 12 for each link destination is referred to and the updated portion is analyzed.

A more specific description will be given with reference to FIGS. 7 and 8. FIG. 7 shows a display of the Web page 50 of the above-mentioned A newspaper company. The update style of the Web page 50 of newspaper A is "By unit, add from top". Web
On page 50, the information is displayed in units of "society", "international", "sports" and "economy". In the example of FIG. 7, each unit has a bar display 5
Sectioned by 1A, 51B, 51C and 51D,
Images 52A, 52B, 52C and 52D are displayed at the beginning of each bar display 51A, 51B, 51C and 51D, and titles 53A, 53B, 53C and 53D indicating each unit are displayed. Below each bar display 51A, 51B, 51C and 51D,
The information of each unit is displayed in a digest form.

In the example of FIG. 7, a link to a Web page in which detailed information is posted is attached to each digest-like information. Therefore, a viewer who has accessed the web page 50 can access a web page linked to the digest-like information and browse further detailed information.

With respect to such a Web page 50, it is analyzed whether or not information has been updated for each unit. For that purpose, first, it is necessary to extract a portion indicating a unit from the web page 50. As a method of extracting a part indicating a unit, for example, an HT displaying the web page 50
A method of extracting text data representing a title for each unit in the ML file can be considered. Web page 5
In 0, when the title is displayed by the image data, the unit portion can be extracted by the file name of the image data.

FIG. 8 shows a part of the source (contents of the HTML file) for performing the display of FIG. 7 described above. In addition,
In FIG. 8, in order to avoid complexity, only a portion necessary for explanation is extracted and displayed from the actual source, and other portions are omitted.

As is well known, in HTML, various commands and parameters are described by being surrounded by tag symbols "<" and ">" using text data. The image file displayed on the Web page, the URL of the link destination at the time of direct link, and the like are described in the HTML file while being surrounded by tag symbols together with a predetermined command and the like. Also, the tag symbol "<a href="URL">" that represents a link is used in combination with the corresponding tag symbol "</a>", and for the text sandwiched between these two corresponding tags, A link to the web page indicated by "" URL "" can be set. Below, the commands, parameters,
Also, the combination of corresponding tags is collectively referred to as a tag.

Further, the text displayed on the Web page is directly described as text data in the HTML file. Therefore, from the HTML file
By extracting the description of the image file or text data used to display the unit title,
The unit part of the b page 50 can be extracted.

In the example of FIG. 8, the tags 61A, 61B, 61
C and 61D show images 52A, 52 of FIG.
B, 52C and 52D are designated respectively, and tags 62A, 62B, 62C and 62D respectively designate titles 53A, 53B, 53C and 53D of each unit and links to detailed information. For example, the unit “society” in the web page 50 in FIG. 7 can be extracted by searching the HTML file of the web page 50 for a combination of the tag 61A and the tag 62A. With respect to the other units “international”, “sports”, and “economy” in the web page 50, the unit can be extracted by the same method.

The extraction of the unit in the Web page 50 is not limited to this example. For example, in the example of FIG. 8, tags 60A, 60B, 60C and 60D that represent comments.
Shows the outline of the contents of each unit.
These tags 60A, 60B, 60 from the TML file
C and 60D can be detected to extract a unit.

Similarly, the tags 63A, 63B, 63C and 63D representing the comments for each unit may be detected to extract the unit. Taking the comment tag 63A as an example, for example, information on how many bytes the unit information starts from the comment tag 63A is acquired in advance, and the unit is extracted based on the position of the comment tag 63A and this information. To do.

Further, for example, in the example of FIG. 8, tags 62A, 62B, 62C and 62 indicating links to detailed information.
Since each D includes text data for displaying the unit title, these tags 62A, 62
B, 62C and 62D can be detected in the HTML file and the unit can be extracted. Furthermore, when texts are not used to display the title of a unit and different image data is used for each unit, the unit can be extracted by detecting the file names of those image data. .

In this way, when the unit on the Web page 50 is extracted, the posting information for each unit is extracted. In the example of FIG. 8, the extraction of the posted information is performed by using a tag (for example, “<ah
ref = "national / update / 0130 / 019.html">","<a href
=) Part) may be detected, and although omitted in FIG. 8, it is also possible to detect a tag indicating image data displayed at the beginning of each publication information. In this way, the information extracted for each unit is aggregated and the corresponding W stored in the pre-update information database 12 for each link destination.
The updated information is analyzed by comparing each with the information on the eb page.

It should be noted that, as with the Web pages of the above-mentioned newspaper companies and government offices, Web pages with high publicity, regular,
In Web pages where information is frequently updated, standard forms are often used for a relatively long period of time. For example, in the example of A newspaper company mentioned above, the form as shown in FIGS. 7 and 8 is used for a period of several months or more. Therefore, it is possible to easily analyze and collect the update information by making the Web page into a template and holding it. The template is, for example,
It can be created based on the source of the Web page as shown in FIG. 8 described above.

In this way, when the update information of the Web page is collected, in step S2, selection of publication / non-publication in the link collection and selection of genre based on additional information among the collected update information are determined. Etc. are performed by the operator.

FIG. 9 shows an example of the configuration of a link collection setting screen 40 for the operator to select whether or not to publish the Web page in the link collection, to decide the genre selection, and the like. The link collection setting screen 40 is provided by, for example, the in-house HP server 10, and by accessing the in-house HP server 10 from the personal computer apparatus 17 connected to the intranet 1 in a predetermined manner, the personal computer apparatus 1
It is displayed on 7. The operator can set the link collection as described above by operating the personal computer 17 in a predetermined manner based on the display of the link collection setting screen 40.

On the link collection setting screen 40, additional information of each Web page collected based on the link destination information stored in the link destination information database 11 is listed. In the example of FIG. 9, the display unit 41 displays the additional information collectively for each website in which the additional information is posted. At this time, with respect to the Web page whose update style is “By unit, add from top”, each additional information is further displayed by being collected by unit.

For each of the additional information displayed on the display unit 41, the publication / non-publication, genre and link method are set. Information publication / non-publication is selected and set by the input unit 42. The genre of information is input section 4
It is set by 3. It is preferable that the input unit 43 be able to select one of a plurality of genres registered in advance, for example, because the operator's burden is reduced. Input section 4
According to 4, it is selected and set whether the link to the Web page in which the information is posted is a direct link or whether only the URL is displayed in the link collection.

It is possible to set default values for the respective settings in the respective input sections 42, 43 and 44 of FIG. For example, it is possible to set a predetermined set value as an initial value in a previously input state and use it as a default value. In the example of FIG. 9, each of the input units is
The side indicated by "● (black circle)" is set as default. The default value can be set for each website or for each unit.

In the above description, it is explained that the link collection setting screen 40 displays additional information of links.
This is not limited to this example. That is, on the link collection setting screen 40, it is possible to continuously display the link information published in the link collection from the previous time. In this case, for example, the set value at the time of the previous operation can be used as the default value. By doing so, it is possible to change the setting for the link information continuously posted on the link collection setting screen 40. It is also possible to delete the previously published link in the link collection.

When the setting for each of the additional information is completed, the operator operates the enter button 45 in a predetermined manner. As a result, the set contents are registered in the link information database 13. Link information database 1
The registered contents of No. 3 are reflected in the in-house link collection published to the intranet 1 by the in-house HP server 10 (step S3 in FIG. 2).

FIG. 10 shows an example of the structure of the link information database 13. The input sections 42, 43, and 44 on the link collection setting screen 40 shown in FIG. 9 and the items “publication” and “genre” of the link information database 13
And "presence / absence of link" correspond to each other. Also,
The item “posting date and time” of the link information database 13 describes the date and time when the operator operates the enter button 45 to post a link to each piece of information in the link collection. The items “information source” and “posting title” correspond to the information displayed on the display unit 41. For the item "Delete posting",
It will be described later.

Note that, in FIG. 10, a part (link / URL display of “C individual, XX treaty impression”) of the link collection setting screen 40 of FIG. 9 described above is changed to the link information database 13. The case where it is registered is shown.

In addition to the information newly registered by registering the above-mentioned additional information, the link information database 13 also registers past information in which the URL of the link destination in the link collection is valid. ing. The links are registered in these link information databases 13,
It is generated from newly registered additional information and previously registered information. At this time, the link collection is generated as a date-specific link collection 16, a genre-specific link collection 14 and an information-source-specific link collection 15 for each of the items “posting date”, “genre” and “information source” of the link information database 13. To be done.

When referring to each Web page on the Internet 3 from the intranet 1 based on the link collection thus generated, the firewall 2 is once passed through as described above. In this firewall 2,
The reference count information database 20 is connected, and the measurement result obtained by measuring the reference count for each Web page by the firewall 2 is stored as the reference count information. Based on this reference count information, the sorting order in the link collection is
It can be expected that the link collection will become more convenient by changing it according to the information source.

Rearrangement of the sorting order in the link collection will be described with reference to FIG. When a Web page on the Internet 3 is referenced from the intranet 1 based on the link collection, the URL of the referenced Web page is acquired by the firewall 2. By storing this URL in the firewall 2, the reference history as an example shown in FIG. 11A is stored in the firewall 2.

From this reference history, the number of times of access to the same website is measured for each website. For example,
In the example of FIG. 11A, the URL “http://Ashinbun.co.jp/ma
in.html "," http://Ashinbun.co.jp/rekisi.html ",
"Http://Ashinbun.co.jp/movie.html" and "http: /
"/Ashinbun.co.jp/seibu.html" is the website
Since the "http://Ashinbun.co.jp/" part indicating the location of the server (computer device) where the site is constructed is common, it can be determined that the websites are the same. URLs “http://Bkancho.gr.jp/hakkou.html” and “http://Bkancho.gr.jp/jouyaku.html” are also determined to be the same website in the same manner. Here 1
Only the items are displayed, but the URL "http: //Ckojin.n
For “e.jp/xx.html”, the identity of the websites is also determined in the same manner.

Based on the result of this determination, the number of accesses to the same website is measured for each website.
FIG. 11B shows the measurement result. Note that here, U
The website indicated by RL "http://Ashinbun.co.jp/" is the A newspaper, the website indicated by URL "http://Bkancho.gr.jp/" is the government office B, and the URL "http: // Ckojin.n
The website indicated by "e.jp/" is represented as C individual. These pieces of information can be obtained, for example, by referring to the link destination information database 11 based on the URL.

When the number of references to each website is measured, each website is given a priority order based on the measurement result. As shown in an example in FIG. 11C, the websites are prioritized in descending order of reference frequency.

This priority and link information database 1
A link collection is generated based on the registered contents of No. 3. 12
Shows a display of an example of the link collection 60 generated based on the priority order. The link collection 60 is based on the genre-based link collection 14. The links are displayed in descending order of priority for each genre. How to arrange the genres
It may be fixed, or similar to the above, the priority order may be obtained and arranged for each genre.

Here, it is expected that the newly added Web page or the like will have a low access frequency due to this link collection and inevitably have a low priority. Therefore, it is preferable to display the newly added Web page at a priority position regardless of the access count measurement result.

In the link collection 60, an underlined link destination indicates that "link" is selected on the link collection setting screen 40 and a direct link is set.

Next, consider the case where the information at the link destination disappears. Information existing in a website, that is, a web page, may be deleted, for example, by the administrator of the website after a certain period of time has elapsed since the information was posted. Whether or not a Web page is deleted after a certain period and at what timing is deleted by each We
b Depends on the site management policy. As described above, the disappearance timing of this Web page is previously investigated and stored in the item “Disappearance of information” of the link destination information database 11. The content of the item “disappearance of information” of the link destination information database 11 is reflected in the link information database 13. This content is further reflected in the generated link collection.

That is, in the website for which the linked information is automatically collected, even if the link of the web page in the website disappears, if the web page itself does not disappear, from the link collection. Can be linked. On the other hand, if the web page itself disappears along with the disappearance of the link to the web page in the website, the link from the link collection is also impossible. At this time, it is necessary to delete the link to the Web page in the link collection. Information indicating whether or not the link information is deleted due to the disappearance of the Web page is stored in the link information database 13.

For example, as shown in a part of the link destination information database 11 in FIG. 13A, the item "disappearance of information" is displayed.
Is set for each information source, that is, for each website. Among these, regarding the website for which the item “Disappearance of information” is “when not posted”, when the link to the Web page disappears from within the website, the Web page is also considered to have disappeared, and the link The value of the item “posted deletion” in the information database 13 is set to “immediate deletion”. In this case, when it is detected that the link to the Web page in the Web site is lost when the Web site is circulated for updating the link collection, immediately, that is, the link collection of the current time When updated, the publication of the Web page in the link collection is deleted.

On the other hand, if the item "disappearance of information" in the linked information database 11 is "one year from publication",
Even if the link to the Web page disappears from the Web site, the Web page itself is considered to exist, and the item “posted deletion” in the link information database 13
The value of is set to "deleted after one year's update". In this case, when the website is visited to update the links,
If it is detected that the link to the Web page on the website has disappeared, the link to the Web page will be deleted when the link collection is updated one year after the detection. It
