2. Description of the Related Art Recently, a plurality of server computers and a plurality of client computers are connected via a network, and multimedia data having a hypertext structure is stored in each server computer. Systems capable of browsing various multimedia data have become widespread. Examples of such a system include, for example, WW on the Internet.
There is a system called W (world wide web).

At present, a document including multimedia data is generally described in a description language called, for example, HTML (hyper text markup language). According to HTML, it is possible to embed a text document, a still image, a moving image, music data, an application program such as a Java (registered trademark) applet, and to set a link structure from a document to a document.

That is, such a document (hereinafter referred to as “HT”)
ML page ". ) And multimedia data are each assigned a unique address called a URL (uniform resource locator). The user can access a desired HTML page or multimedia data by specifying a URL on the browser. In addition, a link for accessing another page or multimedia data is embedded in the HTML page, and the user points to this link on the browser to display the linked page or multimedia data. It is possible to move. As described above, a hyperlink is realized in the HTML page, and a file can be easily accessed from a file only by following a link from a certain file to another file.

In an HTML page, a title sentence of a document can be defined using an HTML title tag (<title>), so that the title can be extracted.
You can get an overview of the content from the title without having to read the entire file.

Here, as a browser which is HTML document display software on a client computer, for example, Netscape C
ommunicator (registered trademark) or Microsoft Internet
Products such as Explorer (registered trademark) are widely used.

[0007] When a user clicks a "bookmark" or "favorite" button when an HTML page of interest is displayed, the browser software displays the URL of the HTML page.
There is a function to memorize. This is a mechanism in which, when accessing the same URL again, a URL list of “bookmark” or “favorite” is displayed and clicked with a mouse without re-inputting the URL address.

Here, referring to FIGS. 8 to 11,
The "bookmark" or "favorite" function of the browser software (hereinafter referred to as "bookmark function") will be described.

For example, in the hypertext shown in FIG. 11, the user can change the information link from “http: // lcdnews /” to “liquid crystal news (http: // news
/991123.html) ”and click“ http: // news / 9911
23.html ", and the user liked the content of this article, and clicked the bookmark registration button 101 (FIG. 10) of the browser to add" http: //news/991123.html "to the bookmark file. "Is recorded.

[0010] Similarly, when the user enters “http: // source /”
Clicked on "Nara Tourism (http: //topics/a.html)" to access "http: //topics/a.html". Then, it is assumed that the user likes the content of this page and clicks the bookmark registration button 101 of the browser to record the content in the bookmark file.

By the above operation, “http: // news / 99112
3.html "and" http: //topics/a.html "are the user's" favorite pages ", and their URL addresses are stored in the bookmark file.

FIG. 8 is an explanatory diagram of the data structure of the bookmark file. As shown in FIG. 8, the bookmark file stores a URL address and a title as a set. FIG. 9 is a description example in which the bookmark file of FIG. 8 is expressed in HTML.
FIG. 10 shows the HTM of the bookmark file shown in FIG.
11 is a display example in which a description example of L (FIG. 9) is displayed on an HTML browser. That is, FIG. 10 is a display example of a conventional bookmark file.

Here, the titles in FIGS. 8 and 10 are as follows:
<Title></ tit in HTML file of favorite page
This is a character string extracted between le> tags (the first line in FIG. 9), and is used to represent the title of the HTML page.

On the fourth line in FIG. 9, "http: // news /
The hyperlink to “991123.html” is “<a href = http: //
news / 991123.html> http: //news/991123.html </a> ”.

As shown in FIGS. 8 and 9, the table of the bookmark file is an HTML file. And
The bookmark file table is displayed by clicking the bookmark display button 102 in the browser.
It is displayed in the HTML display area 103 and can be accessed again simply by selecting and clicking on a specific URL address on the screen.

However, since the URL of the accessed URL is often recorded on a daily basis, the URLs listed in the bookmark file increase day by day.
On the other hand, the URL recorded in the bookmark is more likely to be deleted by the server administrator as the day passes. If the URL no longer exists, a list of the bookmark files is displayed, and even if the recorded URL address is clicked, the desired information cannot be accessed, and an access error in which the destination is completely closed is generated. Become. Therefore, there has been a problem that URLs that cannot be accessed in the bookmark file increase with time, and the utility value gradually decreases.

To solve this problem, Japanese Patent Laid-Open Publication No. Hei 11-39327 (published on 1999 (1999)
9) Feb. 12) ", a link information automatic restoration method and device, such as indicating a directory higher in the URL, is proposed.

[0018] This is the link "http: //www.omron.c
o.jp/CC/JPN/org.html ”cannot be found by moving, changing, deleting, etc., the upper directory“ http: /
/www.omron.co.jp/CC/JPN/ ”,“ http://www.omron.co.jp/
jp / CC / ”and“ http://www.omron.co.jp/ ”are presented as link destination candidates.

[0019]

However, in the above-described conventional method, only the upper layer of the Web server having the same URL as the link destination URL can be obtained as the related link. Therefore, the range of selectable link information destination candidates is extremely limited, and it is insufficient to access information related to the lost URL address.

In particular, when the link destination URL recorded in the bookmark is not found, in order to find the URL related to the lost link destination URL, the URL of the link source at the time of first accessing the URL and recording the bookmark is searched.
There was a need to easily access the RL.

[0021] The present invention has been made to solve the above problems, and an object of the present invention is to provide a hypertext system, such as WWW, which can be used even if the link destination URL no longer exists. UR of content

The link management unit 1 records a bookmark (URL address, title, link source URL address) of a file to be accessed via the network access unit 2 in the link storage unit 3, and also stores a bookmark file according to a user's instruction. 3a is a link storage unit 3
And display it on the display unit 4. At this time, by inputting an instruction such as a click on the browser, the bookmark file 3a is accessed so that the corresponding file can be accessed from the URL address and the link source URL address.
Is input to the display unit 4 in HTML format.

The link storage unit 3 includes a nonvolatile memory 1
4, and stores a bookmark including the URL address, title, and link source URL address of the accessed file in the bookmark file 3a under the control of the link management unit 1.

The display unit 4 is, for example, an HTML browser.
The display of the TML file and the display of the bookmark file 3a are performed on the display device 17 under the control of the CPU 12.

Next, referring to FIGS. 3 and 4,
The operation of the link management unit 1 will be described. First, the operation of recording a bookmark will be described with reference to the flowchart of FIG.

Here, the character string variable U is stored in the memory 13.
Storage areas for RL1, URL2 and the character string variable TITLE are secured. The character string variable URL1 is the URL of the file currently displayed on the browser on the display device 17.
Store the address. The character string variable URL2 stores the URL address of the link source of the currently displayed file. The character string variable TITLE stores the title of the currently displayed file. Further, the temporary variable URLi + 1 holds the URL address currently being displayed. The temporary variable URLi holds the previous display URL address.

In step S1, a URL displayed in the HTML display area 23 (FIG. 7) of the browser of the display device 17 is displayed.
Is a state in which the user is browsing the contents (standby state).

In step S2, an input operation such as a mouse click is detected from the input device 16 (FIG. 2), and if the user issues an instruction to shift to the next link (eg, click on the temporary variable URLi + 1), the flow proceeds to step S3. .

In step S3, the temporary variable URLi + 1
Is stored in a character string variable URL1, and the temporary variable URLi is stored in a character string variable URL2.

In step S4, the temporary variable URLi + 1
The contents of the HTML file of network access unit 2
From the Web server at the end of the network. Then, the read HTML file is subjected to document analysis, and if there is a sentence surrounded by “<TITLE>” tags,
3 is stored in the character string variable TITLE.

In step S5, a temporary variable URLi + 1
Is displayed in the HTML display area 23 (FIG. 7) of the browser of the display device 17.

In step S6, if the bookmark registration button 21 (FIG. 7) is clicked, the contents currently stored in the character string variables URL1, TITLE, URL2 (link source URL address) are registered in the bookmark. Specifically, “bookmark.html” which is the bookmark file 3a (FIG. 1) is read, and the character string variable URL is read.
1, the contents stored in TITLE and URL2 are added and written out, and the bookmark file 3a is updated.

In step S7, the temporary variable URLi + 1 is substituted for the temporary variable URLi, and the process returns to step S1.

In step S3, the URL is directly input to the URL address input section 24 (FIG. 7) of the browser.
Is input or a URL is selected from the bookmark file, the character string variable URL2 is cleared.

According to the above procedure, a bookmark in which the link destination URL, title, and link source URL are registered as a set can be recorded in the bookmark file.

Next, the operation of displaying a bookmark will be described with reference to the flowchart of FIG.

In step S11, an input operation such as a mouse click is detected from the input device 16 (FIG. 2), and when the bookmark display button 22 (FIG. 7) is clicked,
Proceed to step S12.

In step S12, "bookmark.html" which is the bookmark file 3a (FIG. 1) is read, and
It is displayed in the HTML display area 23 (FIG. 7) in the form of a list of bookmarks including the character string variables URL1, TITLE, and URL2 (link source URL addresses).

The bookmark file 3a is
The information may be stored in the link storage unit 3 in the HTML format, or may be stored in the link storage unit 3 in another format.
May be converted to the HTML format by the link management unit 1 when the data is displayed. Furthermore, in the present embodiment, the bookmark file 3a is described in the HTML format and displayed in the HTML display area 23 (FIG. 7). However, the link destination URL and the link source UR are determined according to the bookmark selected by the user.
If L can be accessed, the file format used for display can be arbitrarily selected.

Next, the bookmark file will be described in detail with reference to FIGS.

Here, consider a case where a hyperlink as shown in FIG. 11 is accessed. The user must first enter “http: // l
It is assumed that the user accesses “cdnews /”, accesses “http: //news/991123.html” (“LCD News”) linked to “LCD News,” and registers this as a bookmark. Go to “http: // source /” and link to “Nara Tourism” at “http: // topics / a.
html ”(“ Recommendations for Nara Tourism ”), and suppose that this is registered in a bookmark.

In the present embodiment, since the link source URL is also stored at the time of bookmark registration, the bookmark file 3a is recorded in a data structure as shown in FIG. FIG. 6 is a description example of the bookmark file in the HTML format in the above example. Also, FIG.
5 is a display example in which a TML file is displayed on an HTML browser. FIG. 7 shows a display example in which the bookmark display button 22 is pressed to display the bookmark file 3a.

As shown in FIG. 6, the bookmark file is, for example, an HTML format text file (“bo
okmark.html ”) and the non-volatile memory 14 (FIG. 2)
Is stored. Then, "<tab
HTML tags such as “le>”, “<tr>”, and “<td>” are used.

As a result, as shown in FIG. 7, the bookmark can be displayed on the browser in the form of a table in which the user can click the URL address and the link source URL address.

That is, in FIG. 7, there is a hyperlink to “http: //news/991123.html” in which a bookmark is registered, and by simply clicking this, “http: // news /
"Http: // lcdnews /" which is the link source URL address of this page is also displayed in a state where a hyperlink is provided, and by simply clicking this, "http: /" is displayed. / lcdnews / ”is displayed.

Therefore, even if “http: //news/991123.html” no longer exists after a lapse of time after bookmark registration, the link source URL address (“http: // lcdnews Clicking on "/") allows the link source information to be displayed on the HTML browser. As a result, even if “http: //news/991123.html” no longer exists, “http: //news/991123.htm
“http://www.sharp.co.jp” which is information similar to “l”
/ ”,“ Http: //news/1.html ”,“ http: //news/2.htm
l ”etc. can be easily found.

In addition, “http: /
The same is true for “/topics/a.html”. Since the link source URL address “http: // source” stored as a pair can be easily accessed, “http: //topics/a.html” no longer exists. However, you can easily access similar information such as “http: //nara/daibutu.html”.

As described above, a desired page (“http: // new
s / 991123.html ”or“ http: //topics/a.html ”, even if you do not have access to it, collect the URL addresses of pages related to the information (LCD related companies, news, etc.) http: // lcdnews / ”or“ http: // source ”, which is a collection of URLs for Nara tourism related pages, so you can easily follow links to related pages. The link source URL address is a useful link for the user, and the bookmark according to the present embodiment is more convenient than the conventional bookmark.

As described above, the information source recording apparatus according to the present embodiment records a bookmark by pairing a link destination URL and a link source URL, thereby obtaining the link source U.
This makes it easy to return to the RL.

As a result, even if the link destination URL recorded in the bookmark cannot be found anymore, the link source URL can be easily accessed, so that the URL of the same category or a similar category as the lost link destination URL can be easily found. be able to. That is, since the page to which the URL address of interest was originally linked (the link source URL address) can be easily accessed,
Information related to the lost URL address can be easily obtained.

For example, as shown in FIG.
When the bookmark file 3a is displayed in the TML display area 23, "http: //news/991123.html"
(“LCD News”), if it no longer exists, the user can immediately access the link source “http: // lcdnews /” and easily access the URL of the related content.

Here, for example, “http://www.yahoo.co.jp
Many WWW sites that are famous for their directory services, such as "/" and "http://www.yahoo.com/", have many similar URL addresses linked to the same page by category. Use hyperlinks wisely "(Nikkei Science, September 1999 pp
According to 28-35), in the world of the hyperlink structure of the Internet, many links related to one page are often set, and this is called a hub.
It is described as a sociological phenomenon: "Humans are born to create a hub that expresses their expertise on a topic."

Therefore, if the information source recording apparatus according to the present embodiment is used to record the so-called hub URL as the link source URL of the bookmark, the link destination UR
Even when L cannot be accessed, many related URLs can be easily accessed from the link source URL, which is more effective.

The present embodiment does not limit the scope of the present invention, and various changes can be made within the scope of the present invention.

For example, in the present embodiment, HTML has been described as an example. However, the description language is not limited to HTML as long as it can describe a hyperlink. Also,
Link source UR when the link destination URL cannot be accessed
The access to L may be performed in response to a user's instruction or automatically without waiting for the user's instruction.
