DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing the embodiments. FIG. 1 is a diagram showing an outline of a person involved in the system configuration of a program distribution system using an electronic mail signature according to the present invention.

[0007] Provided data registration means 12 is arranged on the computer 1 of the data provider. For example, this is realized in a folder format as shown in FIG. 2, and provided by providing the provided data 11 in the folder by drag and drop, the registration is realized.

[0008] Provided data 11 to provided data registration means 12
Is registered, the feature of the provided data is extracted by the feature extracting means 13. For example, if the provided data 11 is text information, a keyword in the text is provided. If the provided data 11 is in the MP3 format, index information is provided. By realizing the feature extraction function described above, it is possible to easily extract the features of the provided data 11.

[0009] The feature information of the provided data 11 extracted by the feature extracting means 13 is transmitted to the server 2 via the extracted feature transmitting means 14.

[0010] All of these controls are realized in, for example, a folder format as shown in FIG. 2, and if a mechanism is completed in which the provided data 11 is put into the folder by drag and drop, the data provision is completed. The user can easily register the provided data 11.

The feature information of the provided data 11 sent from the extracted feature transmitting means 14 is extracted by the extracted feature receiving means 22 of the server 2 to determine where the feature information and the provided data are held in which data provider computer. The information is registered as a set with the provided data management means 21.

The number of feature information of the provided data 11 registered in the provided data management means 21 is large because the feature information of the provided data 11 provided by many data providers is held. Therefore, as an example, it is necessary to perform some sort of organization using hierarchical structure management or the like. The basic information for organizing the data is stored in the data organizing information management unit 23, and the provided data organizing unit 24 organizes the information in the provided data managing unit 21 based on the information in the data organizing information management unit 23. Get organized.

In order to organize the data, for example, when all the provided data is text information and the organization is performed by hierarchical clustering, the data organizing information managing means 23 stores the correspondence data between the classification information and the keyword. The provided data organizing means 24 clusters the provided data based on the correspondence data by using the keyword of the characteristic information held in the provided data management means 21.

As described above, when a large amount of provided data 11 is registered, the method of using the data is as follows. The provided data browsing means 25 realized on the server 2 allows the data user 3 to browse and search the provided data. It becomes possible.
This browsing search method is, for example, as shown in FIG.
A folder called provided data is placed on the data user 3's computer, and when the folder is opened, there is a hierarchically managed folder group. This is the same operability as file management held on its own computer. Alternatively, a format in which a search function based on a keyword and a hierarchical classification are mixed, such as a search site on the Internet, may be realized.

When the data user 3 tries to obtain the actual provided data, the provided data browsing means 25 determines the obtained data and executes the obtaining process. It is also possible to obtain information on the location of actual data, and use this information to realize an environment in which a data request is sent directly to the data provider's computer. Further, in this series of data acquisition processing, if the data user 3 determines the acquisition data by the provided data browsing means 25 and executes the acquisition processing, it is easy to realize an environment in which the processing is automatically performed. An environment for obtaining provided data can be realized as if the file were copied from another drive on the computer.

[0016]

As described above, according to the present invention, provided data 1
1 itself is stored on the computer 1 of the data provider, and the server 2 manages only the characteristic information and the location of the data, thereby realizing a data sharing environment. As a result, information sharing environments such as intranets,
The present invention provides excellent effects, such as easily realizing an environment for a data distribution service, and further, an operating environment for a search site on the Internet.
