Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a related web page presentation system.

[0002]

2. Description of the Related Art Conventionally, a large number of web pages such as a home page and an information providing page have been established on a network such as the Internet, and a large number of web page users have been connected to the Internet such as a personal computer and a mobile phone. Free access (visit) from connected terminal devices
Thus, various kinds of information can be easily collected in a short time. In particular, recently, the spread of terminal devices, the speed of communication lines, the content of web pages,
Along with the enhancement of information to be provided, the convenience of web pages has been enhanced, and the number and functions of websites that provide search services, such as portal sites, have been enhanced, and access to web pages to obtain desired information The number of users
The number of times and time have increased significantly.

[0003]

However, in an information search system that provides a search service like the conventional portal site, a web page including a search word given by a user is extracted and extracted. Although a list of web pages is displayed as a search result, since various types of web pages are mixed in the list, it is possible to select a web page required by a user from the list. Have difficulty.

[0004] For example, when a user intends to purchase a personal computer, generally, the information required by the user is reported by those who have already purchased and used the personal computer. It is a user report in which the feeling of use of the personal computer is posted. However, in a conventional information search system, when a search is performed using the model name of the personal computer as a search term, a web page of a maker that manufactures the personal computer, a web page of a selling store, and A list that includes a user's web page etc. is displayed as search results.

[0005] For this reason, it is difficult for the user to understand what kind of web pages are included in the list and how much the web pages are included in the list. Selecting and extracting pages is a very time-consuming task for the user.

In order to solve such a problem, when a user selects a web page including necessary information from the list, information related to the information posted on the web page is displayed. An information search system having a related page search function for outputting a list of web pages is provided (www.google.com).
reference).

However, in the information retrieval system,
Since only a list of one type of web page closely related to the web page selected by the user is displayed, the user can see what other types of related web pages exist, Also, we cannot know how relevant it is. Therefore, when the object of the user's interest shifts to different types of related information, browsing a web page on which the related information is posted requires a troublesome operation.

For example, when the user selects a personal computer user's web page from a list of search results, the related page search function outputs a list of web pages of other users. Then, if the user who was browsing the web page of the user wants to find out about the store of the personal computer next, the user returns to the top search result and searches for the store page. Then, the list of the web pages of the store must be output using the related page search function again.

As described above, in the conventional information retrieval system,
When the object of interest of the user changes, even if the changed object of interest is related to the first object of interest, the user must repeatedly perform cumbersome operations.

[0010] Further, there is a portal site that provides various web pages by classifying them by type and allows a user to browse related web pages one after another (www.
w. yahoo. com). However, in such portal sites, the work of classifying and associating web pages is performed manually, and the number of web pages that can be provided is limited. Also, web pages on the Internet are frequently updated, moved, and deleted, which can be costly to keep information current.

The present invention solves the above-mentioned conventional problems,
By presenting a group of web pages in which information in the same field as the information posted on the web page specified by the user from a very large number of web pages, information on the field of interest to the user Can be browsed efficiently, and by presenting the existence of a group of web pages that publish information in a field adjacent to the field, the object of interest of the user becomes adjacent. It is an object of the present invention to provide a related web page presentation system capable of efficiently browsing a group of web pages on which information in an adjacent field is posted even when the user moves to a field.

[0012]

For this purpose, in the related web page presentation system of the present invention, the web pages are classified into groups based on the correlation of the hyperlinks provided between the web pages. Calculating a degree of association between the groups, and a related page database creating means for creating a related page database, and upon receiving a transmission from the user terminal, accessing the related page database, and Control means for acquiring a group including the group, a group related to the group, and a degree of association between the groups, and transmitting the acquired group to the user terminal.

The Internet 21 has a number of WWWs (World Wide Webs, not shown).
A page, that is, a web page is established. The web page displays information such as virtual shops, electronic catalogs and other EC sites for performing EC (electronic commerce), entertainment information, traffic information, science and technology information, company information, financial transaction information, academic information, and the like. Information service sites, portal sites that provide site search services, ASP sites that provide various application services such as music and software distribution, and homepages of individuals, companies, organizations, governments, and the like. The web page is generally set up on a computer such as a personal computer or a server having a computing unit, a storage unit, a communication interface, an input / output unit, etc., and a large number of users are sent from the user terminal 22 via the network. To access (visit).

[0028] The web page may be an individual, a company,
It may be operated by any person such as an organization. In addition, access to the web page may be free, paid, partially paid, and even if an unspecified number can be accessed, only a registered person or a person who has signed a contract can access it. May be something.

Furthermore, even if the web page is of an interactive type that can also receive information from the user terminal 22, all or a part of the posted information can be used for free or for a fee. It may be one that can be downloaded.

Reference numeral 10 denotes an information retrieval system communicably connected to the Internet 21 via a public line or a dedicated line. The information retrieval system includes a computer having an arithmetic unit, a storage unit, a communication interface, and an input / output unit. Built inside. The computer may exist alone or may be a distributed server in which a plurality of computers are organically coupled. Further, another system may be built in the computer.

The information retrieval system 10 includes a page collection means 11 for collecting web pages, a collection page database 12 for storing the collected web pages,
Hyperlink database creating means 13 for creating a database relating to hyperlinks between web pages,
The hyperlink database 14, which is a database relating to the hyperlink, a related page database creating means 15 which creates a database relating to a related web page, the related page database 16, which is a database relating to the related web page, and the related page database 16 are accessed. Control means 17 for obtaining necessary information, input control means 18 for accepting external access to the information search system 10, and output control means 19 for transmitting information to the outside of the information search system 10.

Next, the operation of the information retrieval system having the above configuration will be described.

FIG. 2 is a diagram showing an example of how hyperlinks are provided between web pages, FIG. 3 is a diagram showing an example of the form of data stored in a related page database, and FIG. FIG. 5 is a first diagram illustrating an example of a display mode, FIG. 5 is a second diagram illustrating an example of a mode of displaying a web page group, and FIG. 6 is a third diagram illustrating an example of a mode displaying a web page group. FIG. 7 is a fourth diagram showing an example of a mode of displaying a group of web pages.

First, the page collection means 11 automatically accesses a web page established on the Internet 21 via the Internet 21, and obtains a URL (Uniform Resource Lo) of the web page.
cator), and copy the posted information or the like, that is, collect web pages. Then, the collected web page is stored in the collected page database 12. The page collection means 11 collects web pages at appropriate times and updates the contents of the collection page database 12 to keep it up to date.

Here, the collected page database 12
The number of web pages stored in the URL may be any number, but it is desirable that the number is large to some extent. For example, it may be about 4,000 to 5,000, but may be one billion or more. Further, the web pages stored in the collection page database 12 may be collected manually.

Next, the hyperlink database creating means 13 accesses the collection page database 12, extracts hyperlinks between the stored web pages, and stores them in the hyperlink database 14. . Here, the hyperlink is HT
ML (Hyper Text Markup Lang)
When a character string sandwiched between anchor tags is clicked in (uage), a jump is made to a file or a character string specified by the anchor tag.

As a result, the hyperlink database 14 stores information on which web page a hyperlink is attached to, that is, information on a link source web page and a link destination web page.

The hyperlink database creating means 13 directly accesses a web page established on the Internet 21 via the Internet 21 without accessing the collection page database 12, and generates a link between the web pages. The hyperlink attached to the URL may be extracted.

Next, related page database creating means 1
5 accesses the hyperlink database 14 and analyzes how hyperlinks are provided between web pages. Then, the web pages are classified into a number of groups, the degree of association between the groups is calculated, and the calculated degree is stored in the associated page database 16.

Here, the operation of the related page database creating means 15 will be described in detail.

(1) Create a web page list related to each web page. For convenience of explanation, a case will be described in which the web page list is created using a simple algorithm.

First, a web page list related to each of the web pages (P1, P2,... PN) included in the hyperlink database 14 is created. Here, a web page list Lk related to a certain web page Pk is created as shown in the following (a) to (c).

(A) The hyperlink database 14 is accessed, and a web page that has a hyperlink to the web page Pk, that is, a web page (B1, B2) that is a link source of a hyperlink having the web page Pk as a link destination ,... BM).

(B) Then, by accessing the hyperlink database 14, the web pages (B1, B
2,... BM) are obtained as a list of web pages to which all hyperlinks are linked. Subsequently, the number of times each of the web pages is listed in the list is counted.

In the case of the example shown in FIG.
The web pages at the link source of the hyperlink with k as the link destination are B1 and B2. And web page B
The web pages Pk, Pk are included in the list of web pages to which the hyperlinks having the link sources 1 and B2 as link sources are linked.
m and Pn are listed. The number of listings is two for the web page Pk, two for the web page Pm, and one for the web page Pn.

(C) Some (for example, top 10) web pages are extracted from the top in descending order of the number of times of listing, and a related web page list Lk for the web page Pk is created.

In the case of the example shown in FIG.
When one web page is extracted, a list listing web pages Pk and Pm is created.

Then, the hyperlink database 14
All web pages (P1, P2, ...)
PN), a web page list related to each is created as described in (a) to (c) above.

Note that when creating a related web page list for each web page, instead of using the simple algorithm described above, other algorithms,
For example, an algorithm called Companion (Jeffrey Deandand Monika)
R. Henzinger. Finding rela
ted pages in the World Wi
de Web. Proceedngs of the
8th International World
Wide Web Conference, 199
9. : See).

(2) Classify web pages into a plurality of groups.

Next, based on the web page list created in the above (1), the web pages (P1, P2,... PN) included in the hyperlink database 14 are divided into a plurality of groups (G1, G2,...).・ GM)
In addition, the web page list includes (a) in (1) above.
To (c) or other algorithms, for example, C
It may be created using an algorithm such as "opampion".

Here, two web pages, namely,
Regarding the combination consisting of the web page Pi and the web page Pj, if the web page Pi and the web page Pj satisfy the following condition (a), they are classified into the same group, and if not, they are not classified into the same group. I do.

Condition (a): The web page Pj is included in the associated web page list Li for the web page Pi, and the web page Pi is included in the associated web page list Lj for the web page Pj.

Satisfaction of the condition (a) means that relevant information is posted on the web page Pj from the viewpoint of information posted on the web page Pi, and that the information is posted on the web page Pj. Since the information related to the web page Pi is viewed on the web page Pi, it can be said that the information posted on the web page Pi and the web page Pj are related to each other. Therefore, if the condition (a) is satisfied, the web page P
i and web page Pj are in the same group, for example,
It is classified into group Gi.

On the other hand, when the condition (a) is not satisfied,
Since the information posted on the web page Pi and the web page Pj cannot be said to be related to each other, the web page Pi and the web page Pj are not classified into the same group.

Then, the hyperlink database 14
All web pages (P1, P2, ...)
PN) is checked to see if the condition (a) is satisfied, and all web pages (P1, P2,... PN) are grouped into a plurality of groups (G1, G2,.
G2,... GM). That is, all the web pages included in each group satisfy the condition (a).

Note that another condition can be set in place of the condition (a). For example, condition (b): n or more web pages Pk included in the associated web page list Li for the web page Pi are included in the associated web page list Lj for the web page Pj (where n is 1 Integer greater than or equal to). May be set, or any other condition may be set as long as the relationship between the web page Pi and the web page Pj can be defined and classified into groups.

(3) Calculate the degree of association between each group.

Next, based on the web page list created in (1), the degree of association between all the groups created in (2) is calculated. Here, the degree of association between the two groups, that is, the group Gi and the group Gj, is obtained as shown in the following (a) to (c).

(A) The number of times that the web pages included in the group Gj are listed in the associated web page list for each of all the web pages included in the group Gi is counted, and the numbers are totaled. Let Rij be the one.

(B) The number of times the web pages included in the group Gi are listed in the associated web page list for each of all the web pages included in the group Gj is counted, and the numbers are totaled. Let Rji be the one.

(C) The sum of Rij and Rji is defined as the degree of association between group Gi and group Gj.

Then, for all the groups (G1, G2,... GM) created in the above (2), the degree of association between them is calculated as in the above (a) to (c). Then, as shown in FIG. 3, it is stored in the related page database 16.

The data stored in the related page database 16 includes U of the web page included in each group.
RL and the degree of association between each group are included.

Thus, when a certain web page is specified, the group to which the web page belongs, the other group to which the web page is included, the group related to the group, Items such as what kind of group exists in the group, what kind of web page is included in the related group, and how much related degree the related group has, etc. It can be easily grasped.

Next, access from the user terminal 22 via the Internet 21 is accepted by the input control means 18, and the URL of the web page designated by the user is received.
Is transmitted to the control means 17, the control means 17 accesses the related page database 16 and searches for the specified web page. Then, data on a group including the specified web page and a group related to the group is acquired.

Subsequently, when the control means 17 transmits the acquired data to the output control means 19, the output control means 19 edits the data so that the data can be browsed, and transmits the data via the Internet 21. To the user terminal 22. That is, the group including the designated web page and the titles of the web pages included in the group related to the group are displayed so as to form a group for each group, and the degree of association between the groups is displayed. Edit so that it can be browsed in such a form and send it.

The display means of the user terminal 22 includes
Web page groups in which information in the same field as the information posted on the web page designated by the user are displayed as shown in FIGS.

Then, a hyperlink is formed in the title of the displayed web page, and when the pointer is clicked with the pointer displayed on the display means of the user terminal 22, the corresponding web page can be accessed. Is desirable.

Thus, when the user designates one web page containing the object of his / her interest, the user can easily grasp the web pages included in the same group as the web page, and Web pages included in a group related to are easily grasped.

Although there are various forms for displaying the group of web pages, FIGS. 4 to 7 show some typical display methods.

Then, the group related to the group including the web page specified by the user can be displayed on the display means of the user terminal 22, as shown in FIG. In this case, the group including the web page specified by the user is located at the top of the screen, and related groups are displayed below the group in descending order of relevance.

FIG. 5 shows a group of the web pages.
, Can be displayed on the display means of the user terminal 22. In this case, a group including the web page specified by the user is located substantially at the center of the screen, and related groups are displayed around the group.

Further, as shown in FIG. 6, related groups can be displayed by connecting them with straight lines. An index indicating the degree of association between groups may be added to each of the straight lines. For example, a number as an index representing the degree of relevance may be given to the straight line, or the thickness of the straight line may be changed according to the degree of relevance to be an index representing the degree of relevance,
The color of the straight line may be changed according to the degree of relevance to serve as an index indicating the degree of relevance. Also, a curve or a polygonal line can be used in place of the straight line.

Although the groups whose relevance is lower than a predetermined numerical value (for example, 10) are not displayed, they may be displayed according to a user's instruction. The URL of the web page included in each group is converted into the title of the web page and displayed as shown in FIGS.
The RL may be displayed as it is, or the title and the URL may be displayed together. Further, a part of the web page may be displayed below each title.

In FIGS. 4 to 6, the groups are displayed by enclosing the title of the web page included in each group with a rectangle. For example, a line may be drawn between the groups, The groups may be displayed by other methods, such as encircling the titles of web pages included in each group.

Further, by displaying as shown in FIG. 7, it is possible to display more groups related to the group including the web page specified by the user by the user. In the figure, each rectangle represents one group. In this case, the group 58 including the web page specified by the user is displayed in the left frame in the figure, and groups related to the group 58 are arranged. The state of a large number of groups related to the group including the web page specified by the user can be grasped over a wide range.

In FIG. 7, each group is represented by a rectangle and numbered, but can be represented by other methods. For example, circles or other shapes may be used instead of rectangles, or icons may be used. Further, the title of the first web page included in the group may be given instead of the number.

In FIG. 7, the related groups are displayed by connecting them with a straight line. An index indicating the degree of association between groups may be added to each of the straight lines. For example,
A number as an index indicating the degree of relevance may be given to the straight line, the thickness of the straight line may be changed according to the degree of relevance to serve as an index indicating the degree of relevance, or the color of the straight line may be related. The index may be changed in accordance with the degree to indicate the degree of relevance. Also, a curve or a polygonal line can be used in place of the straight line.

Further, when the pointer or the cursor is placed on the rectangle of the group and clicked on the screen of the display means of the user terminal 22, the title of the web page included in the group is changed to an independent frame as shown in FIG. It is desirable to be displayed within. In this case, it is further desirable that a corresponding web page can be accessed when a pointer or a cursor is put on the rectangle of the group and clicked. Further, it is desirable to display which group is displayed in the independent frame in the left frame in the figure.

As described above, in the present embodiment, the information retrieval system 10 lists the web pages related to each of the web pages based on the correlation between the hyperlinks provided between the web pages. Then, a web page list is created, web pages are classified into groups based on the correlation between the web page lists, the degree of association between the groups is calculated, and a related page database 16 is created.

Further, the control means 17 edits the group including the designated web page and the group related to the group so that the group can be viewed on the user terminal 22 and transmits the edited group. .

Therefore, when the user accesses the related page database 16 and designates one web page, to which group the web page belongs and what other web pages belong to the group What pages are included, what groups are in the groups related to the group, what web pages are included in the relevant groups, and how much are the relevant groups It is possible to easily grasp items such as whether or not the degree of relevance exists.

Further, the information retrieval system 10 analyzes a hyperlink, creates a web page list, classifies web pages into groups, uses a predetermined algorithm without manual operation, and Since the relevance is calculated, the relevant page database 16 can be created in a short time, easily, accurately, and at low cost.

Further, even if a large number of web pages and hyperlinks are newly created, updated, and abolished, the related page database 16 can be updated immediately at any time.

Furthermore, the present invention is not limited to the above-described embodiment, but can be variously modified based on the gist of the present invention, and they are not excluded from the scope of the present invention.
