DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to guiding a user to an information page according to the purpose and interest of the user among contents (hereinafter referred to as information pages) of a plurality of information media on a computer network. The present invention relates to an information medium navigation apparatus and method, and a medium recording the program.

[0002]

2. Description of the Related Art On a computer network, there are a large number of information pages using a plurality of information media such as texts, images, voices, etc., and a user who refers to these information pages usually refers to them for some purpose or interest. Generally, there are a plurality of users who have a common purpose or interest.

[0003] When information pages having a common purpose, interest, topic, etc. are linked using hypermedia or the like, a virtual community (virtual community) as a group of information pages relating to a common purpose, interest, topic, etc. is created. It can be used to guide users to information pages according to their purpose and interests (information media navigation).

[0004] Hypermedia is text,
This is a mechanism that links information pages provided by a plurality of information media such as images and sounds so that related information can be referred to.

FIG. 1 shows a state of conventional information media navigation, in which a plurality of users having a common purpose or interest are referring to the same or different information pages. At this time, if more detailed information or new other information is required for the information page referred to by the user, a link to another information page on the referred information page as shown in FIG. It is necessary to move the information page to be referred to.

[0006]

However, in this method, when information is completed on the page referred to, that is, when there is no related link and no community is formed, a search page or the like is used. There is a problem that a user must actively search for a related information page. There is also a problem that the user may move out of the information page (outside the community) on the purpose, interest, and topic of the user while moving the link.

Further, in order to form a group (community) of information pages having a common purpose and topic, mutual links are required between information pages, and as the number of related information pages increases, link maintenance costs increase. was there.

Further, when users having a common purpose or interest use a search site to search for information pages related to the purpose or interest, differences in search capabilities between the search sites used, search skills, and The search results may not always match because the keywords associated with the keywords that require input differ from user to user, and the information page indicated by the link in the search results does not necessarily form a community. Are not always the same, despite having the same purpose and interests,
There is a problem that a common purpose, topic, or community of interest cannot be shared among users, and a plurality of similar communities are randomly created, thereby hindering information sharing.

The present invention utilizes a hypermedia capable of efficiently coordinating a plurality of information media, and a community and a user as a group of users having a common purpose, interest, and topic are routinely used. By linking the information page being referred to (browsing) with a link and automatically displaying community information related to the link information of the information page being viewed by the user at the same time that the user browses the information page To realize information media navigation that enables a user to browse information pages in a chain without actively searching for a community, and further allows a community to be freely customized according to a user's request. The purpose is to:

[0010]

SUMMARY OF THE INVENTION According to the present invention, in a conventional virtual community, an entire information page created by a user using various information media is converted into a set of information pages classified according to a common topic, content, and purpose. Hierarchically, the information page is linked to the community, which is a group of users who have the same purpose and interest, as a link using hypermedia, and the community can be freely customized according to the user's request. By enabling this, the similar problem of disturbing the sharing of similar communities, which is a conventional problem, avoids the problem that information sharing is hindered, and is related to the information page that the user is viewing at the same time as the user browses the information page Automatically display community information to enable browsing of related information pages in a chain. By, conventional, while providing information media navigation that can avoid the problem that must be actively searching for another information page about the purpose and interests that have the user in question,
Conventionally, the navigation bar that manages the current location of the community or the information page that the user is browsing and the operation of moving the position is used to move the user to the problem page while moving the link of the information page that the problem user is browsing. Also solves the problem of moving to outside the information page (outside the community) related to the purpose, interest, and topic of the user, and the problem that link maintenance increases when the number of information pages increases when forming a community between information pages Is what you do.

FIG. 6 shows a processing procedure of an operation request for a community server by a user client according to the embodiment of the information media navigation method of the present invention.

The user uses the user client 200 to transmit an operation request to the community server 100 from the request transmission means 202 to the community server (s01). Here, it is assumed that user A browses subcommunity A as an operation request. The community server receives the operation request by the request receiving means 110 (s
02), access control is performed by the access control means 111 in the following procedure (s03).

First, the received operation request information is decomposed into "user A" as user information and "browse subcommunity A" as operation information (s03, s04).

FIG. 7 shows an example of the relationship between user objects and member objects managed by the community server.

In the community server, user objects indicating users (users A, B, C,...) Who use the community server are managed by a user list comprising a user name and a password by the user management means 105. I have. Also, the member management means 106
Thus, the members participating in the community A manage the users A to D from the user list as a community member list. Further, members who belong to the sub-community A belonging to the community A manage the users A and C from the community member list of the community A as a sub-community member list.

Thus, since the user A is a member of the community A and a member of the sub-community A, it is determined that the user A is in the “member mode” (s05 to s1).
0).

Next, the procedure for checking the operation authority (s11) will be described.

FIG. 8 shows an access control list object storing access control information of objects managed by the community server. The access control list object is
(1) `` non-members '' indicating that they are not members of the community, (2) `` restricted members '' indicating that they are members of the community but not members of the sub-communities, and (3) Read (Read) and write objects for each "member" indicating that they are members of the community, (4) "owner" indicating that they are the creator of the object, and (5) "user" indicating each user. (Wri
te), execution of operations related to the community (Execu
te), and the access permission information for each user is prioritized.

Since the community objects are managed in a tree structure, the information of the access control list object of the community object close to the root community object has priority.

The community tree has a structure as shown in FIG. 9, and reading (Read) for the root community object is permitted, and reading (R) for the community A object is permitted.
e) is permitted and subcommunities A
Since reading (Read) for the object is permitted, user A is permitted to read (Read) the subcommunity A object. Therefore, browsing of subcommunity A by user A is permitted.

In FIG. 9, reference numeral 300 denotes a root community; 310, a list of subcommunity objects; 320, creation of community B; 330, movement / link or deletion of community C; 340, creation of subcommunity B; Indicates movement / link or deletion of subcommunity A.

Thus, the community server is operated by the operation execution unit 112 and the object management unit 101.
Reads object information of subcommunity A (s

Send to user client as W page (s1
3).

In the user client, the resulting W
The WW page is received by the request result receiving means 203 (s1
4) The WWW page is displayed by the information page automatic display means 206 (s15).

FIG. 10 shows a processing procedure for displaying community information corresponding to the embodiment of the information media navigation method of the present invention.

The user uses the user client 200 to start browsing the WWW page A indicated by URLA by the information page display means 201 (sp01). The user client hooks the URL of the WWW page A being browsed by the browsing information page hooking means 204, and sends a search request for the community or subcommunity to which the URLA belongs to by the community server by the belonging community searching means 205 and the request transmitting means 202. Automatically (sp02).

The community server 100 receives the search request by the request receiving means 110 (sp03). After the access control means 111 checks the access control in the procedure for requesting the operation of the community server to be described later (sp04), the community search is performed. The means 107 searches the community or subcommunity to which the URLA belongs (sp05).

In FIG. 5, since the community to which the URLA belongs is the community A and the subcommunity is the subcommunity A, the request result transmitting means 113 transmits information on the community A (URL-MC) and information on the subcommunity A (URL). -SC) to the user client (sp06). At this time, the navigation bar management means 109 in the community server
The current pointer indicating the current position of the navigation bar is set in the community A and the sub-community A, and the current pointer is held and, at the same time, the information of the community A and the sub-community A is transmitted to the user client as a WWW page.

In the user client, the search result is received from the community server by the request result receiving means 203 (sp07), and the community navigating means 209 sets the current pointer indicating the current position of the navigation bar on the user client side to the community A and the sub-user. It is set in the community A, and the current pointer is held by using the Cookie. At the same time, the information of the community A and the sub-community A is automatically displayed as a WWW page by the information page automatic display means 206 (sp.
08).

By operating the navigation bar displayed on the user client, the user navigates the community or sub-community or the WWW page by the community navigation means 209 (sp09).

As shown in FIG. 11, the navigation bar includes two community move buttons 401 for instructing the community server to move the community tree and a request to move the sub-community ring to the community server. And three WWW page move buttons 403 for instructing the community server to request to move a WWW page ring belonging to the subcommunity. .

The user sets the WWW page to the last WW
Move to W page D and WWW page A of First
Automatically move to the first or WWW page A of First
By moving to the last WWW page D automatically, the navigation by the pseudo ring structure of the WWW page is performed. Similarly, the subcommunities are navigated by a pseudo ring structure. Accordingly, the user can efficiently browse the sub-community A and the WWW pages belonging to the sub-community A without departing from the community A.

Also, by holding the current pointer in the community server, when the user client reconnects, the community, subcommunities, and WWW pages can be browsed (resume) from the previously browsed state, Also, by holding the current pointer in the user client at the same time,
Even if the user departs from the community while following the link on the WWW page registered in the sub-community, the user can forcibly return to the community information page of the current pointer that is stored.

Next, the user makes a request to the community server by the community creation / deletion requesting means 207.
A request is made to create a community B and a sub-community B for the URL of the WWW page A that the user is browsing, and the link registration / deletion requesting unit 208 changes the URL of the WWW page that the user is browsing to the sub-community. A case in which registration with B is requested will be described.

The community server sequentially processes the above two requests in the following procedure.

FIG. 9 shows the relationship between the structure of the community tree managed by the community server and the sub-communities. The community tree has only one root community object 300, and each community object has a list 310 of subcommunity objects.

As shown in FIG. 8, the user A executes (Exe) the root community object 300.
Since the “cut” is permitted, the community tree management unit 102 creates a new community B object immediately below the root community object 300 on the community tree (32).
0).

Next, as shown in FIG. 8, the user is permitted to execute (Execute) the root community object 300 by the owner, and the community B object controls access to the root community object 300. To take over the list, the sub-community ring management means 103
Then, a sub-community B object is created in the community B object (340).

In response to a request from the user A, the community C object under the community A object is moved, linked, or deleted under the community B object by the community tree management means 102 (330). ) Is possible, and the sub-community A object in the community A object can be moved, linked, or deleted (350) by the sub-community ring management means 103 into the community B object. It is possible.

Next, the details of the object managed by the community server will be described.

FIG. 12 shows property objects managed by the community server. Properties of the object managed by the community server (for example, community name, owner name, validity period, etc. of the community object) are managed as property objects. The property object is
It holds the object path (object name) indicating the object to which the property belongs, the property name of the object to which the property belongs, and the property contents to hold the property contents of the object to which the property belongs.

All properties possessed by the object managed by the community server are held as property objects, and reading and writing of properties by the user is controlled by read (Read) and write (Write) authority in the access control list information.

FIG. 13 shows a link object managed by the community server. The link object includes, as link information, a link name for identifying a WWW page and an object managed by the community server, a link path indicating a location where the WWW page and the object managed by the community server are stored, and a link object. The creator is composed of an owner name indicating the manager and owner indicated by the user object.

FIG. 14 shows community objects managed by the community server.
The community object is a community name for identifying the community, the creator of the community, the owner name indicating the manager and owner, the validity period indicating the period during which the community object can be operated, and the community tree structure Link to the upper community object and the link list of the lower community object, which are community link information to perform, and a subcommunity object which is community information for holding information of a subcommunity object in the community object described later. And a set of property objects consisting of search keywords, which are meta information necessary for searching for community objects.

FIG. 15 shows a sub-community object managed by the community server. The sub-community object is a sub-community name for identifying the sub-community, a creator of the sub-community, an owner name indicating an administrator and an owner, a validity period indicating a period during which the sub-community object can be operated, and a sub-community object. Sub-community link information that holds the community to which the community belongs as a link to the community to which the community belongs, information page link list that is information in the sub-community to hold information of information pages in the sub-community, necessary for searching for sub-communities It consists of a set of property objects consisting of search keywords, which are meta information.

The method of the present invention can be realized by a medium recording software (program) having the procedures shown in the flowcharts of FIGS. 6 and 10 together with well-known hardware such as a CPU, a memory, and an external storage device. It is.
