FIG.
3 is a flowchart of the operation of the second conventional technique.

First, the user requests information by sending commands "next screen", "previous screen", and "end" from the information terminal 1 to the information providing server 2 (step 10).
Hereinafter, such a method of requesting information is referred to as an information request using a command. The command is sent to the information providing server 2 via the computer network 3. The information providing server 2 receives the command name requested from the information terminal 1 via the computer network 3 (step 1).
1), interpret what kind of request the command is (step 12). Here, the “next screen” is a command for searching for information that can be provided as the next screen, the “previous screen” is a command for requesting the previously provided screen again, and the “end” is information provision. This is a command for ending the request and issuing a processing request for disconnecting the connection with the information providing server 2.

The information providing server 2 includes a provided information storage unit 21
When the information provided from the information providing server 2 is searched for and determined (step 13), the information provided by the information providing server 2 to the information terminal 1 is associated with the information structure stored in the provided information storage unit 212 and the information. The user history based on the content ID is used. When the command is “next screen”, information belonging to the same layer (information A to information D) is set as a candidate for information to be provided next. Next, referring to the acquisition status (user history) of the content ID, the information associated with the unacquired content ID is specified as the provision information. When there are a plurality of candidates, the provided information is specified so as to select the content ID with the smaller number first.

[0014] Content ID associated with the selected information
Is added and the user history is updated (step 1
