[Step 10-5] A = 1 and U is set as the second link of the link-containing content 41.
A link 50 to the RL (www.fff.co.jp/6.html) is added with the display form being "red & capital letters".

[Step 10-10] Since A + B = N, the process of changing the display form of the link related to the update is terminated.

[Step 11] Display form changing unit 120
Transmits the link-containing content 41 changed in Step 10 to the content display unit 11, and the content display unit 11 displays the link related to the update in “red” as shown in the example of (b) of FIG. && Capital letters ", and the link relating to the non-updated state displays the link-containing content 41 which has been restored.

As described above, in the first embodiment, when the link-containing content is accessed, the latest access date and time and the latest update date and time of the link destination content related to the link included in the link-containing content are compared. , If the latest update date and time is newer than the latest access date and time and there is link destination content that has not yet been viewed, the link on the link-containing content that indicates the unviewed link destination content is It is displayed in the form.

Therefore, at the time of accessing the link-containing content, it is possible to easily and quickly recognize the link destination content related to the unviewed update.

The latest update date and time of the linked content 43 is not from the Web robot but from the Web server 3
Since it is directly acquired from 1, the linked content 43
It is possible to know the real-time update status of the link content, and when the linked content is accessed via the other linked content 41 without passing through the currently accessed linked content 41, or the linked content 41 It is possible to grasp the link destination content that has not been accessed after the update, taking into consideration the access status when directly accessing.

Furthermore, since the user can set the display mode of the link indicating the unbroken link destination content, for example, even a visually impaired person or the like can be displayed in such a manner that the obstacle does not disturb the user. By setting the form, it is possible to surely know the unbroken link destination content.

Also, for a large number of link-containing contents, since it is not necessary to store the character string relating to the latest contents of the link destination contents indicated by each link included in the link-containing contents, there is a large capacity of memory. There is no need to prepare.

[Second Embodiment] FIG. 19 is a diagram for explaining the function of the Web content update status presentation system according to the second embodiment of the present invention.

In FIG. 19, 10 is a Web client, 11 is a content display section for displaying the link-containing content 41, and 12A is a display condition setting section for setting the display condition of a predetermined link 50 described in the link-containing content. , 13 are storage units.

20 is a network such as the Internet,
Reference numeral 30 is a Web server that holds the link-containing content 41, and 43 is the link-containing content 41 by the link 50.
The linked content is linked to. Also,
Reference numeral 100 denotes a latest update date / time acquisition unit that acquires the latest update date / time of the linked content 43.

110A is the link-containing content 4
Last access date and time to 1 and the linked content 43
Is compared with the latest update date and time of the link destination content 43 related to the link included in the link destination content 43 to determine the update status of the link destination content 43, and the update link list 114A (see FIGS. 20 and 34) is displayed. It is an update status determination unit to be created.

120A includes only the link 50 related to the link destination content 43 satisfying the display condition set by the display condition setting unit 12A in the update link list 114A created by the update status judging unit 110A. A link description processing unit that processes the content to be displayed on the link-containing content 41.

In the present embodiment, as described above, the result of comparison between the last access date / time to the link-containing content 41 and the latest update date / time of the link destination content 43 related to the link included in the link destination content 43, etc. Actually, it is determined whether or not to display the link 50 in the link-containing content 41 based on (also using other comparison results as described later). However, when performing such determination processing, , URL of the link-containing content 41 (Unifo
rm Resource Locator), the date and time of previous and current access to the link-containing content 41, the URL of the linked content 43, and the linked content 4
The latest access date and time and the latest update date and time for 3 are used.

[0225] The meanings of "update" in the first embodiment and "update" in the second embodiment are different. That is, in the first embodiment, the latest update date and time of the linked content 43 is the linked content 4
Although it is determined to be “updated” when it is newer than the latest access date and time of No. 3, in the second embodiment, the latest update date and time of the link destination content 43 is the link-containing content 41 including the link to the link destination content 43. If it is newer than the latest access date and time, it is determined as “update”.

Then, in the second embodiment, regarding the link destination content 43 determined as “update” as described above, the latest update date and time of the link destination content 43 is further the same as in the first embodiment. Determines whether it is newer than the latest access date and time of the linked content 43, and when it is determined that it is new, it is determined as “not accessed (that is, unviewed)”, and when it is determined that it is old, “ Already accessed (that is, viewed) ”.

Note that the relationship between the link-containing content 41 and the link destination content 43 is not fixed; for example, in the case of content linked to each other,
These contents may function as the link-containing content 41 or the link-destination content 43 in the present embodiment depending on whether or not the content is the link source. However, in the following description, in order to facilitate understanding, the relationship between the two is fixed in principle.

FIG. 20 is a functional block diagram showing the functions of the storage unit 13, the update date / time acquisition unit 100, and the update status determination unit 110A shown in FIG.

20, the storage unit 13 stores the display condition list 14A shown in FIG. 31 and the latest access date / time list 15A shown in FIG.

The latest update date / time acquisition unit 100 analyzes the link 50 described in the link-containing content 41 and extracts the corresponding URL, and the analysis unit 10 and 10.
The acquisition unit 102 that accesses the link destination content 43 based on the URL extracted by 1 and acquires the latest update date and time of this link destination content 43, and the latest update date and time storage that stores the latest update date and time list 104A shown in FIG. It has a section 103.

The update status judgment unit 110A is the date / time comparison unit 1
12A and the update link storage part 113 are included. The date / time comparing unit 112A compares the last access date / time to the link-containing content 41 with the latest update date / time of the link destination content 43 related to the link 50 included in the link destination content 43, and determines update / non-update. For both of the linked contents 43 determined to be “updated”, the latest access date and time and the latest updated date and time of the linked contents 43 are further compared to determine unaccessed (unviewed) / accessed (viewed). Then, the updated link list 114A is created based on those determination results.

FIG. 31 shows an example of the contents of the display condition list 14A held in the storage unit 13. Display condition list 1
The URL list of 4A includes the UR of the content 41 containing the link.
L is stored. Then, in the display condition list of the display condition list 14A, the link destination content 4 indicated by the link 50 in the link-containing content 41 related to the URL.
3 has been updated after the last access date and time to the link-containing content 41, under what conditions does the link 50 include the link-containing content 4
The display condition indicating whether to display on 1 is stored.

FIG. 32 shows an example of the contents of the latest access date / time list 15A held in the storage unit 13. The URL list of the latest access date / time list 15A stores the URLs of all the contents accessed by the Web client 10, and the latest access date / time list stores the latest access date / time for the content.

FIG. 33 shows an example of the contents of the latest update date / time list 104A. The latest update date / time list 104A stores the URL of the link destination content 43 related to the link 50 described in the link-containing content 41 and the latest update date / time of the link destination content 43.

FIG. 34 shows an example of the contents of the update link list 114A. A URL for registering the URL of the link destination content 43 related to the link 50 described in the link-containing content 41 in the update link list 114A.
An update status column and an access status column are formed corresponding to the columns.

[0236] In the update status column, "update" is stored as the update status of the link destination content 43 indicated by the URL in the URL field. In addition, in the present embodiment, regarding the link destination content 43 related to “unupdated”, the URL and the like are not listed at all in the update link list 114A.

Here, the update status refers to whether or not the link destination content 43 indicated by the link 50 in the link-containing content 41 has been updated after the last access date / time to the link-containing content 41. If it is updated after the last access date and time, it is determined as “update”, and if it is updated before the last access date and time, it is determined as “not updated”.

The access status column stores the access status regarding the linked content 43 whose update status column is "updated". Here, the access status refers to whether or not the linked content 43 related to the update is updated after the latest access date and time to the linked content 43, and is updated after the latest access date and time. In the case, it is determined as “not accessed” (that is, not browsed), and in the case where it is updated before the latest access date and time, it is determined as “already accessed” (that is, browsed).

In the case of "already accessed", the "already accessed" is not recorded in the access status column.
It becomes "blank". In addition, each list of FIGS.
It can be created and presented using the Cookie function of the Web browser.

Next, a method of presenting the update status of Web contents in this embodiment will be described.

FIG. 21 shows that, if the link destination content 43 related to the link 50 included in the link-containing content 41 has been updated after the date and time when the link-containing content 41 was last accessed, the link 50 will be updated.
It is a figure showing the flow of the processing which displays on the link content 41 concerned.

FIG. 22 is a flow chart corresponding to FIG. An outline of the link display processing will be described with reference to FIGS. 21 and 22.

[Step 20] When the user wants to set the display condition of the link 50 related to the update on the link-containing content 41, the user sets it by the display condition setting unit 12A in the Web client 10. The set display conditions are
It is stored in the display condition list of the display condition list 14A.

The display condition setting process will be described later in S.
It may be performed in an application program that performs the processing in steps 21 to 30 or may be performed by another application program such as a Web browser or a dedicated application program.

The link 50 of the link-containing content 41 for which the display condition setting process has not been performed is displayed when the default display condition is satisfied. This S
Details of the processing in step 20 will be described later in detail with reference to FIG.

[Step 21] Web Client 1
0 requests the Web server 30 to access the link-containing content 41, and transmits the latest access date / time of the link-containing content 41 stored in the latest access date / time list 15A as the previous access date / time.

[Step 22] Web Client 1
When 0 accesses the link-containing content 41,
The storage unit 13 stores the current date and time as the current access date and time in the latest access date and time list corresponding to the URL of the link-containing content 41 of the latest access date and time list 15A.

If the URL of the link-containing content 41 related to the access is not registered in the URL column of the display condition list 14A or the latest access date / time list 15A, the storage unit 13 lists the URL in the list 14A, 1
Register at 5A. This is so that the user does not have to enter a URL that is prone to input errors.

[Step 23] The Web server 30, which has received the access request to the link-containing content 41, requests the latest update date / time acquisition unit 100 to access the link-containing content 41 and the previous access to the link-containing content 41. Send the date and time.

[Step 24] Latest update date / time acquisition unit 1
00 is the link-containing content 41 related to the access request
The link destination contents 43 relating to all the links 50 therein are accessed, the latest update date and time thereof are acquired, and the latest update date and time list 104A is created. The details of the process of Step 24 are as described with reference to FIG. 6 in the first embodiment.

[Step 25] Latest update date / time acquisition unit 1
00 transmits the latest update date / time list 104A and the previous access date / time to the date / time comparing unit 112.

[Step 26] Update status determination unit 110
The date / time comparing unit 112 in the table indicates the latest update date / time of the link destination content 43 for the N link destination contents 43 described in the latest update date / time list 104A transmitted from the latest update date / time acquisition unit 100, and Compare with the last access date and time of the access content 41,
The updated link list 114A is created based on the comparison result.

In this case, as described above, the linked content 43 whose latest update date and time is newer than the previous access date and time.
Is registered in the update link list 114A as "update", and the update link list 1 is updated for the link destination content 43 whose latest update date is older than the last access date.
Nothing is registered in 14A. The details of the process of Step 26 will be described later in detail with reference to FIG.

[Step 27] Update status determination unit 110
The date and time comparing unit 112A in A further compares the latest update date and time and the latest access date and time for the M pieces of link destination content 43 that have been “updated” in Step 26, and thus the link destination content related to the update. It is determined whether or not 43 has been accessed (browsed), and if the result of the determination is non-access, that effect is added to the update link list 114A.

In this case, as described above, link destination contents whose latest update date and time are newer than the latest access date and time are additionally registered in the access status list of the update link list 114A as "not accessed (unviewed)", and the latest For the linked content whose latest update date is older than the access date, that is, in the case of “already accessed (viewed)”, the access status column is left “blank”. In addition,
Details of the processing of Step 27 will be described later in detail with reference to FIG.

[Step 28] Update status judging unit 110
A transmits the updated link list 114A to the link description processing unit 120A.

[Step 29] Link description processing unit 12
0A searches the display condition list 14A in the storage unit 13 and acquires the display condition corresponding to the link-containing content 41 including each URL (link 50) related to the update stored in the update link list 114A.

Details of the processing of this Step 29 are shown in FIG.
Will be described later in detail.

[Step 30] Link description processing unit 12
0A is the link 50 in the link-containing content 41.
Is described or deleted according to the display condition and the content of the update link list 114A acquired in Step 29.
Details of the processing of Step 30 will be described later with reference to FIG.

[Step 31] Link description processing unit 12
0A transmits the changed link-containing content whose link description has been changed in Step 30 to the content display unit 11 for display.

Details of the link display condition setting processing in Step 20 of FIGS. 21 and 22 will be described below with reference to the flowchart of FIG.

[Step 20-1] For the predetermined link-containing content 41 accessed by the user, if the display condition of the link related to the update is to be registered, the URL of the link-containing content 41 for which the display condition is to be registered is set to W.
Select from the display condition list 14A created using the Cookie function of the eb browser.

[Step 20-2] If only the link 50 corresponding to the unaccessed link destination content 43 among the link destination contents 43 related to the update is displayed,
If the link 50 related to the update is displayed and the corresponding link 50 is displayed even if it has been accessed, the process proceeds to Step 20-3.

[Step 20-3] Of the link destination contents 43 related to the update, only the link 50 corresponding to the unaccessed link destination content 43 is designated to be displayed.

[Step 20-4] As long as it is the link destination content 43 related to the update, the corresponding link 50 is designated to be displayed even if it has been accessed.

[Step 20-5] The specified contents are registered in the display condition column of the display condition list 14A.

Details of the update link list creation processing in Step 26 of FIGS. 21 and 22 will be described below with reference to the flowchart of FIG.

[Step 26-1] Update status judging unit 1
10A receives the latest update date / time list 104A transmitted from the latest update date / time acquisition unit 100 in Step 25.

[Step 26-2] T is set as the initial setting.
Set it as = 1.

[Step 26-3] For the URL of the T-th (1-N) link destination content 43 stored in the latest update date / time list 104A, refer to the latest update date / time.

[Step 26-4] If the latest update date and time of the link destination content 43 related to the T-th URL is present, proceed to Step 26-5.
Proceed to Step 26-8.

[Step 26-5] Update status judging unit 1
The date / time comparing unit 112A of 10A compares the latest update date / time of the link destination content 43 related to the T-th URL with the previous access date / time of the link-containing content 41 including the link 50 to the link destination content 43.

[Step 26-6] If the latest update date / time of the link destination content 43 is newer than the previous access date / time of the link-containing content 41, Step 26-7
If not, go to Step 26-8.

[Step 26-7] In the update status column corresponding to the T-th URL of the update link list 114A,
Set "Update".

[Step 26-8] If T = N, the update status comparison process is terminated. If T <N, the process proceeds to Step 26-9. As described above, if the latest update date / time of the linked content 43 is older than the previous access date / time of the link-containing content 41, St
Update link list 11 by proceeding to ep26-8
In 4A, only the link related to "update" is registered, and the link related to "unupdated" is not registered. This makes it possible to reduce the memory capacity to some extent.

[Step 26-9] Add "1" to T and return to Step 26-3.

Details of the additional registration processing to the update link list in Step 27 of FIGS. 21 and 22 will be described below with reference to the flowchart of FIG.

[Step 27-1] Update status judging unit 1
10A requests the storage unit 13 for the latest access date and time of the M link destination contents 43 associated with the URL registered as "update" in the update status list of the update link list 114A.

[Step 27-2] The latest access date / time of the M link destination contents 43 transmitted from the storage unit 13 is received.

[Step 27-3] T is set as the initial setting.
Set it as = 1.

[Step 27-4] UR registered as "update" in the update status list of the update link list 114A
Among the M pieces of link destination content 43 related to L, the latest access date and time of the Tth link destination content 43 is referred to.

[Step 27-5] If the latest access date / time of the T-th link destination content 43 is present, proceed to Step 27-6. If not, St
Go to ep27-9.

[Step 27-6] Update status judging unit 1
The date / time comparing unit 112A of 10A compares the latest update date / time of the T-th link destination content 43 with the latest access date / time to the link destination content 43.

[Step 27-7] If the latest update date and time of the link destination content 43 is newer than the latest access date and time, that is, if it has not been accessed, Step 27-8.
If it is not new, that is, if it has already been accessed, it proceeds to Step 27-9.

[Step 27-8] UR registered as "update" in the update status list of the update link list 114A
“Unaccessed” is registered in the access status column corresponding to the URL of the T-th link destination content 43 among the M pieces of link destination content 43 related to L.

[Step 27-9] If T = N, the additional registration process in the access status column is terminated.
If T <N, the process proceeds to Step 27-10. As described above, when the latest update date and time of the linked content 43 is older than the latest access date and time, that is, when the access has already been made, the processing proceeds to Step 27-9, and "already accessed" is not registered in the access status column. By leaving the field "blank", the processing speed can be increased to some extent.

[Step 27-10] Add "1" to T and return to Step 27-4.

Next, Step 29 in FIGS.
The process will be described in detail with reference to the flowchart of FIG.

[Step 29-1] The link description processing section 120A displays the display conditions corresponding to the currently accessed link-containing content 41 in the display condition list 14A.
Search above.

[Step 29-2] Display condition list 1
If the ULR of the link-containing content 41 is stored in 4A, the process proceeds to Step 9-3. If not, the process proceeds to Step 29-4.

[Step 29-3] Display condition list 1
The display condition registered in 4A is designated as the display condition of the link 50 on the link-containing content 41.

[Step 29-4] The default display condition is set as the display condition of the link 50 on the linked content 41.

[Step 29-5] The link description processing unit 120A displays the display conditions registered in association with the URL of the link-containing content 41 in the display condition list 14.
Get from A.

Next, details of the link processing processing in Step 30 of FIGS. 21 and 22 will be described based on the flowchart of FIG.

[Step 30-1] The link description processing unit 120A receives the update status determination unit 110A from the Step 28.
The updated link list 114A transmitted in step S1 is received.

[Step 30-2] Here, T = 1 is set as an initial value.

[Step 30-3] Link 5 corresponding to the T (1 to N) th URL in the update link list 114
0 is the above display condition and update link list 1
According to the contents of the update status column and the access status column of 14A,
It is described in the link-containing content 41 including the link 50.

For example, the display condition is "not accessed after update".
In this case, if the update status column of the update link list 114A is “update” and the access status column is “blank”, the display condition is not satisfied, so the corresponding link 50 is not described and the update link list If the update status column of 114A is “updated” and the access status column is “not accessed”, the display condition is satisfied, and therefore the corresponding link 50
Describe. Further, when the display condition is “update”, the display condition is satisfied only if the update status column of the update link list 114A is “update”. Therefore, regardless of the contents of the access status column, The corresponding link 50 is described.

[Step 30-4] If T = N,
If T = N, the process proceeds to Step 30-5.

[Step 30-5] Add "1" to T and return to Step 30-3.

When "update" is set as the display condition by such processing, for example, as shown in FIG. 28A, the link destination content 43 updated after the link-containing content 41 is accessed. When only the links are displayed and “not accessed after update” is set as the display condition, for example, as shown in FIG. 28B, the link destination content 43 updated after the link-containing content 41 is accessed. Among them, only the link of the link destination content 43 that has not been browsed is displayed.

With the above processing, when a certain link-containing content 41 is accessed, the link destination content 43 related to the link 50 in the link-containing content 41 is after the previous access to the link-containing content 41. Only when updated, the link 50 can be displayed on the link-containing content 41, and it is possible to completely prevent accidental access to the unupdated link destination content 43. .

At this time, by registering the display conditions,
Alternatively, by setting it as a default display condition, even if the above update is made, it is possible not to display the updated linked content 43 if it has been browsed.
It is also possible to completely prevent accidental access to the browsed link destination content 43.

The latest update date and time of the linked content 43 is not from the Web robot but from the Web server 3
Since it is directly acquired from 1, the linked content 43
It is possible to know the real-time update status of the link content, and when the linked content is accessed via the other linked content 41 without passing through the currently accessed linked content 41, or the linked content 41 It is possible to grasp the link destination content that has not been accessed after the update, taking into consideration the access status when directly accessing.

Also in the second embodiment, the functions of the latest update date / time acquisition unit 100, the update status determination unit 110A, and the link description processing unit 120A are installed in the Web server 30 as shown in FIG. Alternatively, as shown in FIG. 30, it may be installed in the Web client 10. In this case, the Web server 30 or the Web client 10 equipped with the above functions executes the application program (control program) corresponding to each of the above flowcharts.

[Specific Example of Second Embodiment] Next, a specific example relating to the update status presentation processing of the linked content in the second embodiment described so far will be described with reference to FIGS.
This will be described using each list example of No. 4. Here, 2000
Link-containing content 41 accessed on February 10, 2014
(URL is www.aaa.co.jp/1.htm
1) will be described by taking an example of accessing again on March 25, 2000. In this case, the URL is www. aaa.
co. jp / 1. There are two links 50 described in the link-containing content 41 that is html, and the URL of the link destination content 43 indicated by those links 50.
Respectively, www. ccc. co. jp / 3. ht
ml and www. ddd. co. jp / 4. html.

In this case, the URL is www. aaa. c
o. jp / 1. Link-containing content 4 that is html
As shown in FIG. 31, the display condition of 1 is “not accessed after updating”. Also, the URL is www. aa
a. co. jp / 1. The last access date and time of the link-containing content 41, which is html, is February 10, 2000, as shown in FIG.

The latest access date / time list 1 shown in FIG.
In 5A, the URL is www. aaa. co. jp / 1.
The latest access date and time of the link-containing content 41, which is html, is February 10, 2000, but in reality, when the URL is accessed again as described above,
At that time, March 25, 2000, will be recorded as the latest access date and time. Therefore, February 10, 2000, which is shown as the latest access date and time in the latest access date and time list 15A of FIG. 32, is the previous access date and time in this specific example.

Also, the URL is www. ccc. co. j
p / 3. The latest access date and time of the linked content 43, which is html, is March 20, 2000 (see FIG. 32), and the latest update date and time is January 10, 2000 (FIG. 33).
See). Also, the URL is www. ddd.
co. jp / 4. Linked content 4 which is html
The latest access date and time of No. 3 is March 22, 2000 (see FIG.
2), and the latest update date and time is March 21, 2000 (see FIG. 33).

Therefore, in Step 26-5 of FIG. 24, U
RL is www. ccc. co. jp / 3. The latest update date and time “January 10, 2000” of the linked content 43, which is an HTML, and the URL are www. aaa. co. jp
/ 1. Comparing the previous access date and time “February 10, 2000” of the link-containing content 41, which is html, in Step 26-6, the latest update date and time is determined to be older than the previous access date and time, and is determined to be “not updated”. Therefore, by proceeding to Step 26-8, as shown in FIG. 34, URL: www. ccc. co. jp / 3.
html will not be recorded in the update link list 114A.

Also, in Step 26-5 of FIG. 24, the UR
L is www. ddd. co. jp / 4. The latest update date and time of the linked content 43, which is html
21st of the month "and the URL is www. aaa. co. jp /
1. Comparing the previous access date and time “February 10, 2000” of the link-containing content 41 which is html,
In Step 26-6, the latest update date and time is determined to be newer than the previous access date and time, and "update" is determined. Therefore, the processing proceeds to Step 26-7 and, as shown in FIG. 34, the URL of the update link list 114A: www. dd
d. co. jp / 4. “Update” is recorded in the update status column corresponding to html.

Therefore, in Step 27-6 of FIG.
The URL where "update" is recorded is www. ddd. co.
jp / 4. The latest update date and time and the latest access date and time are compared only for the link destination content 43 that is html.

In this example, the URL is www. ddd.
co. jp / 4. Linked content 4 which is html
The latest update date and time of 3 is “March 21, 2000” and the latest access date and time is “March 22, 2000”.
In p27-7, it is determined that the latest update date and time is older than the latest access date and time, and it is determined that "already accessed".
By proceeding to Step 27-9, as shown in FIG. 34, the URL of the update link list 114A: www. d
dd. co. jp / 4. The access status column corresponding to html is "blank".

In this specific example, the updated link list 114A
The link-containing content 41 (UR) including the link 50 indicating the link destination content 43 related to the URL recorded in
L: www. aaa. co. jp / 1. 31), the display condition is "not accessed after update" as shown in FIG.
Since the recorded content of the updated link list 114A does not satisfy the display condition for any of the link destination contents 43, no link is described in the link containing content 41 in Step 30-3 of FIG. It will be.

Therefore, when the link-containing content 41 is accessed, the link destination content 43 linked to the link-containing content 41 is
It becomes possible to instantly recognize that all the latest updated contents have already been browsed, and it is possible to avoid unnecessary access to the browsed link destination content by an erroneous operation.

The present invention is not limited to the above-described embodiments. For example, as a special display form of a link, a special typeface (such as italic) as a link character, a shaded character, and a square are used. It is also possible to use enclosing characters, shaded characters, and the like. It is also possible to make it blink.

Further, the latest update date / time acquisition unit, the update status determination unit, and the display form change unit are not installed together in any of the Web server or the Web client. For example, the latest update date / time acquisition unit is installed in the Web server. By installing the update status determining unit and the display form changing unit in the Web client and distributing the processing functions, small-scale We
b It is possible to reduce the memory capacity on the client side and to further speed up the update status presentation processing.

[0318]

As described above, according to the present invention,
It is possible to present the real-time update status of the linked content indicated by the link included in the link-containing content at the time of accessing the link-containing content, promptly and without using a large capacity memory. .
