(Basic Structure) FIG. 1 is a diagram showing the basic structure of an information processing system according to an embodiment of the present invention.
This information processing system includes a data providing server 100 and a client information device (hereinafter referred to as a client) 20.
It consists of zero. A plurality of clients can be connected to the data providing server 100 at the same time.
In the figure, only one client is shown.

The data providing server 100 stores data usable by a plurality of clients 200, for example, newspaper articles. ○ Month △ Day A newspaper, B newspaper,… ○ Month □ A
When the newspaper, the B newspaper, ... Are stored, the user specifies all the data that the user wants to be provided, such as "B month newspaper on XX month".

This designation may be performed by the client and notified to the server by the communication means, or the user may directly designate the data providing server 100.

The data providing server 100 transmits all designated data.

The client performs a search described later on all the data of "B newspaper of XX month day", and stores and displays only the data desired by the user.

The data providing server 100, when another user designates the "B newspaper in xx month", sends the same data as the client to the other client. In many cases, the other client searches all the transmitted data under conditions different from those of the client, and stores and displays only the data desired by the other user.

That is, the data providing server 100 provides the same data to a plurality of clients 200,
The client 200 stores and displays the data according to the needs of each user.

According to such a data selection method, there is an advantage that the load on the data providing server can be reduced and the data desired by the user can be downloaded in a short time.

FIG. 1 shows the basic internal structure of the client 200. As shown, the client 20
Reference numeral 0 denotes an input unit 10 that receives input of conditions and instructions from a user, a communication unit 20 for communicating with the data providing server 100, and a condition storage unit 3 that stores the input conditions.
