According to the present invention, context data representing a relationship between a plurality of contents is generated by a computer (1-1, 1-2), and the generated context data is stored on a network. (2-1 to 2-
In the method of generating and using the context data stored in 3), the identification information indicating the history of the relationship between the contents is added to the context data. The timing at which the context data is generated by the computer (1-1) on the user side is the link between the contents managed by the operating system or application software by the computer when the user performs a process related to the contents using the computer. For example, when referring to a relationship or a hierarchical structure relationship. At this time, the identification information describes that the identification information is automatically generated based on the action of the general user. In addition, the context data is the computer (1-2) on the advertiser side.
The timing of generation is when the advertiser manually creates an advertisement for content. At this time, the identification information describes that the advertisement is a manually created advertisement. There is no difference other than the identification information between the context data manually created as an advertisement and the context data automatically created by the user's activity. A user or advertiser has at least one computer located on the network
By accessing one of the storage means (2-1 to 2-3) and acquiring at least one context data corresponding to the content of interest from the storage means, at least one of the content directly or indirectly related to the content of interest is acquired. Content can be searched and referenced. When a user or an advertiser searches or refers to content, context data expressing a new relationship between a plurality of contents is automatically generated by a computer, and the generated context data is stored in a storage means. .

In addition, the context data generation and
In one configuration example of the usage method, when the advertiser uses the context data as an advertisement, identification information of the advertisement is added to the context data.
In addition, 1 of the context data generation / usage method of the present invention
In the configuration example, when accumulating the context data in the accumulating unit, the process of generating the context data is recognized based on the identification information added to the context data, and the process according to the recognition result is performed by the accumulating unit.

Functions for performing processing according to the recognition result, and the servers 2-1 and 2-1
-3 is added to the communication function.

Web browser (or XML browser)
Reference numeral 13 is an existing Web browser (or XML browser) added with a function of recognizing the history of context data generation based on the identification information and a function of performing processing according to the recognition result. Similarly, server 2
-1 to 2-3 are functions in which an existing server is added with a function of recognizing the history of context data generation based on the identification information and a function of performing processing according to the recognition result.

In the present embodiment, it is assumed that the user who receives the content is using the computer 1-1, and the advertiser who wants to deliver the advertisement to the user is using the computer 1-2. The user can use the contents stored in the computers 1-1 to 1-3 or the servers 2-1 to 2-3 through the client application 11. The advertiser can use the context data as an advertisement and provide the advertisement to the user.

When the user uses the client application 11 to perform processing relating to a plurality of contents, the client application 11 automatically generates context data expressing the relationship between the plurality of contents for each content. The context data is X
It is described in ML (eXtensible Markup Language) or the like, and is data that can be easily generated by the client application 11.

FIG. 2 shows when the context data is generated. In FIG. 2, PC1
Is an example of a screen of the display device of the computer 1-1 in which the client application 11 is activated. A user of the computer 1-1 operates two file systems A1 and A2 through the client application 11.

In the example shown in FIG. 2, the user uses the computer 1-1.
Operate the mouse connected to and drag and drop the content B in the directory managed by the file system A2 for performing Web services on the Internet to the directory managed by the file system A1 (D1). It shows how it was copied in. The content of the copy destination is named A.

The client application 11 generates the context data corresponding to each of the contents A and B when the user instructs the processing concerning the two contents A and B as described above.

The structure of the context data is shown in FIG.
The context data whose main target is the content A is the address E1 indicating the storage destination of the main target content A.
And related content B related to the main target content A
Address E31, relationship information E21 indicating the relationship between the main target content A and related content B, and relationship information E2
Identification information F1 indicating the history of occurrence of 1 is configured as a main element. The same applies to the structure of context data whose main target is content B.

In the example of FIG. 2, the related content related to the content A is only B, but when the related content is newly generated, the address E3 of the related content is displayed.
2, relationship information E22 indicating the relationship between the related content and the main target content, and identification information F2 indicating the history of the relationship information E22 are newly added to the context data.

As shown by P1 and P2 in FIG. 3, the address E31, the relationship information E21 and the identification information F1 are added as a set, and similarly, the address E32, the relationship information E22 and the identification information F2 are also set as a set. Will be added. In addition, the number of additional pieces is arbitrary.

The main target content address E1 or related content addresses E31 and E32 are the Web
The URL (Uniform Resource Locator) and the path of the file system are stored. Relationship information E21, E2
The attribute 2 includes, for example, information indicating an operation that causes a relationship between the main target content and the related content, such as “copy” or “cited”, and information indicating a user who performed this operation. Data is stored. As the identification information F1 and F2, the history of the relationship between the main target content and the related content, such as “use of content by user”, is stored.

FIG. 4 shows a concrete example of context data generated on the user side. According to the context data shown in FIG. 4, the address of the main target content is the URL “ht
It can be seen that the address of one of the related contents related to the main target contents is the URL "http: // bbb /". Then, it can be seen that the main target content is generated by the copy operation from the related content whose URL is "http: // bbb /" by the user α.

Similarly, according to the context data shown in FIG. 4, it can be seen that the address of the other related content related to the main target content is the URL "http: // ccc /". Then, it can be seen that the main target content is quoted by the user β as related content whose URL is “http: // ccc /”.

As can be seen from FIG. 4, the context data also expresses the relationship between the user and the content (context data). When the user performs a process related to content using the client application 11, the client application 11 has relation information E21 of context data corresponding to the content (context data having addresses of the content in E1, E31, and E32), As E22, attribute data such as a mail address for identifying the user is stored. Thereby, the relationship between the user and the content can be stored in the context data.

The storage of the context data is performed by the servers 2-1, 2-2, 2-which store and manage the context data.
3 is performed by the client application 11 that generated the context data communicating with each other via a computer network.

For example, as shown by C1 in FIG. 1, the client application 11 and the server 2-1 communicate with each other via a computer network, and the client application 11 sends the generated context data to the server 2-1 ( M1).

In this way, the context data is independent of the corresponding content, and the servers 2-1, 2-2, 2- serving as storage means on the computer network.
Accumulated in 3. The servers 2-1, 2-2, 2-3 collectively manage the context data relating to the operation of the same client application, or collectively manage the context data relating to the operation of a plurality of client applications within the same computer. To do

Next, the generation of context data by the advertiser will be described. When the advertiser wants to introduce the content to the user, he or she operates a mouse or keyboard connected to the computer 1-2 and uses an editor provided in the client application 12 to, for example, order the combination of a plurality of contents. Manually edit or create an advertisement that describes the above, or an advertisement that describes the procedure for using multiple contents.

If the advertisement created by the advertiser is related to the contents A and B shown in FIG. 3, the client application 12 uses this advertisement as the related information E21 and identifies it as an advertisement manually created by the editor. Information F1 is added. In addition, the client application 12 uses the advertisements created by the advertiser as the contents A and C.
If the advertisement is related to this advertisement, the advertisement is used as the related information E22, and the identification information F2 indicating that the advertisement is manually created by the editor is added. Relationship information E21, E2
2 stores attribute data including advertisement information created by the advertiser and information indicating the advertiser.

FIG. 5 shows a specific example of context data generated by the computer 1-2 on the advertiser side. The identification information F1 indicates that the related information E21 is an advertisement, and similarly, the identification information F2 indicates that the related information E22 is an advertisement. Then, the related information E21 is created by the advertiser, OO Co., Ltd., and the URL "http: /
Main target content of "/ aaa /" and URL "http: // bbb /"
It can be seen that it includes information explaining the order of the combination of the related contents of. The relation information E22 is ○.
○ URL "http: // aaa /" created by a stock company
It can be seen that it includes information explaining the usage procedure of the main target content of and the related content of the URL “http: // ccc /”.

As can be seen from FIG. 5, the context data also expresses the relationship between the advertiser and the content (context data). When the advertiser creates context data using the client application 12, the client application 12 stores attribute data such as a mail address for identifying the advertiser as the relationship information E21 and E22 of the context data.

The servers 2-1, 2-2, 2-3 receive and store the context data generated by the computer 1-1 on the user side or the context data generated by the computer 1-2 on the advertiser side. In doing so, the process of generating this context data is recognized based on the identification information in the context data.

As described with reference to FIG. 2, when the user performs a process related to a plurality of contents, new context data is automatically generated by the client application 11 and stored in the servers 2-1 to 2-3.

Therefore, after creating the context data having the identification information of the advertisement, the advertiser searches on the network whether new context data related to this context data is created, and the new context data is If it has been created, by referring to this context data, it is possible to know the reaction of the user to the advertisement (for example, whether or not the user is acquiring the content as the advertisement is).

In the example of FIG. 6, the client applications 11 and 12 search and display, but the Web browser (or XML browser) 13 may be used to search and display.

According to the present invention, when a user performs a process related to a plurality of contents, the computer 1-1 generates context data expressing a relationship between the plurality of contents, or the user performs a process related to the content. When
Information in the background of an arbitrary content is generated by generating context data expressing the relationship between the content and the user by the computer 1-1 and accumulating the context data in the servers 2-1 to 2-3 on the network. Can be easily generated as context data and stored on a computer network without the user having to be particularly aware of creating it.

As shown in FIG. 7, the user can easily refer to the context data managed in units of another user or small group via the network.
Since the context data expresses the relationship between the content and the user or the advertiser, the user can easily identify the user or the advertiser related to the content by referring to the context data. In addition, since there is no difference between the context data created as an advertisement and the context data created by the user's activity other than the identification information, the user can distinguish between the context data registered as an advertisement and the context data registered by another user. Both can be freely searched in the same way.

Further, as shown in FIG. 7, the advertiser gives the system administrator an advertisement fee (context data registration fee).
Instead of paying, the context data can be used as an advertisement that presents a procedure for effectively using the content and a method of combining the content with other content. Further, the advertiser can place an advertisement regarding the content on the network without changing the content itself. Then, the system administrator can obtain the advertisement fee from the advertiser instead of managing the context data.

The computers 1-1 to 1-3 and the servers 2-1 to 2-3 are each composed of a hardware resource having a CPU, a storage device and an interface, and a program for controlling these hardware resources. A known configuration may be used. The CPU executes processing according to a program stored in the ROM or RAM or a command input from the keyboard. Further, the CPU can write data in the external storage device and read data from the external storage device.

The program for realizing the context data generating / using method of the present invention is provided in a state of being recorded in a recording medium such as a flexible disk, a CD-ROM, a DVD-ROM, or a memory card. When this recording medium is inserted into the external storage device, the program written in the recording medium is read and transferred to the computer. The CPU then loads the read program into the RAM.
Etc. In this way, the CPU executes the processes of the computers 1-1 to 1-3 or the servers 2-1 to 2-3 described above.

[0064]

According to the present invention, by adding identification information indicating the history of the relationship between contents to the context data, the history of the relationship between the contents (context data) is accumulated on the network. It can be easily identified by the computer on the user side. Since there is no difference between the context data created as an advertisement and the context data created by the user's activity, other than the identification information, the user can use both the context data registered as an advertisement and the context data registered by another user. You can freely search in the same way. According to the present invention, a plurality of contents such as a document group that are related from a certain viewpoint can be collectively presented to the user. Therefore, an advertising medium for efficiently providing context data with context data. Can be used as a kind of. The advertiser can place an advertisement regarding the content on the network without changing the content itself.
Also, the advertiser creates the context data having the identification information of the advertisement, and if new context data related to this context data is created on the network, the advertiser refers to this context data to The user's reaction to can be known.

Further, when the context data is accumulated in the accumulating means, the history of the generation of the context data is recognized based on the identification information added to the context data, and the accumulating means performs the process according to the recognition result. By doing so, for example, the accumulating unit can perform the charging process such as charging the advertiser a registration fee for the context data and freeing the registration of the context by a general user.

Further, after accessing the storage means on the network from the computer to obtain the context data from the storage means, the history of the generation of the context data is recognized based on the identification information added to the context data. , By performing the processing according to the recognition result by the computer, for example, when the relationship between the contents is visualized based on the context data and displayed on the computer, the context data having the identification information of the advertisement is displayed. It is possible to set whether or not to allow the user to avoid referring to the context data that is intentionally registered.
