The basic operation of the electronic information delivery system shown in FIG. 1 will be described below. Here, an example in which the information provider 2 transmits a direct mail to the user 3 will be described. First, the information provider 2 creates electronic information, which is the content of the direct mail, using a personal computer or the like owned by the information provider 2. The electronic information created here is digital data including document data, image data, sound data, and the like. Then, the information provider 2 sends a direct mail dispatch request including the created electronic information to the electronic information delivery system 1. At this time, the information provider 2
Transmits the electronic information to the electronic information delivery system 1 together with the delivery conditions for delivering the electronic information. The delivery condition here is a condition for limiting the delivery destination to which the direct mail is delivered. The age range, hobbies, and preferences of the user 3 are designated, and only the users satisfying the condition are directly sent. It is used to deliver mail.

The electronic information and the delivery conditions transmitted from the information provider 2 are received by the delivery information management unit 12, and the electronic information is held in the delivery information management unit 12. Then, the delivery information management unit 12 outputs the electronic information and delivery conditions held therein to the filter function unit 13. In response to this, the filter function unit 13 refers to the user attribute information file 18 and extracts a user that matches the received delivery condition. Subsequently, the filter function unit 13 separates the electronic information for each user who matches the delivery condition with the individualizing function unit 14.
Output to The electronic information output here is output by the same number as the number of users that match the delivery conditions.

Next, the individualizing function unit 14 performs an individualizing process of adding necessary information for each user to the electronic information received from the filter function unit 13 and converting the information into a direct mail format. In this individualization process, information such as a destination and a sender is given, and a process of inserting electronic information into a predetermined direct mail format is performed. However, the destination here is a post office box ID for specifying the electronic post office box 19 provided for each user 3.

Next, the individualizing function unit 14 outputs the electronic information subjected to the individualizing process for each user to the distribution sorting unit 15. In response, the delivery distribution unit 15 performs distribution based on the destination (post-office box ID) assigned to the electronic information received from the individualization function unit 14 and outputs the electronic information to the electronic post-office box 19. The electronic post-office box 19 receives this electronic information and stores it in a corresponding data file based on the post-office box ID. In addition, the delivery distribution unit 15
In synchronization with the output of the electronic information to the electronic post-office box 19, the user who owns the post-office box that has delivered the direct mail is notified via the delivery server 20 that the direct mail has arrived. Upon receiving this notification, the user obtains the electronic information stored in the electronic post-office box 19 by using a computer or mobile phone that can be connected to the Internet. Thus, the direct mail transmitted from the information provider 2 reaches the user 3.

On the other hand, when the electronic post-office box 19 receives the electronic information from the delivery distribution unit 15 and when the user acquires the electronic information stored in the electronic post-office box 19,
Information indicating that fact is stored in the history information file 16. The information provider 2 transmits a history information reference request to the electronic information delivery system 1 at an arbitrary timing after transmitting the direct mail dispatch request. This history information reference request is received by the history reference unit 17. In response to this, the history reference unit 17 reads history information on the relevant direct mail from the history information file 16, and
The contents are transmitted to the information provider 2.

The information provider 2 acquires the history information transmitted from the history reference unit 17 and confirms the contents. As a result, the information provider 2 can grasp how many direct mails requested to be sent have been sent and how many users have viewed the sent direct mails.
In the above description, the operation when the delivery condition is specified has been described.
D may be designated and delivered directly to the electronic post office box 19.

As described above, the information provider can send a plurality of direct mails to the electronic information delivery system 1 only by transmitting the contents of the direct mail and the delivery conditions. In addition, since direct mail is sent only to users who meet the delivery conditions, mail can be sent efficiently.

FIG. 5 is a flowchart cited for explaining the operation of the autonomous state change tracking electronic information distribution system of the present invention, and each step number is related to that shown in FIG. Hereinafter, the operation of the operation management unit 11 shown in FIGS. 2 and 3 will be described in detail with reference to FIGS.

First, the information provider 2 creates an individual content, and issues a delivery instruction to the autonomous situation change type electronic information delivery system of the present invention together with delivery information (step S51). The delivery information includes a content type and delivery destination information. The information provider 2 can further register the characteristics of the created content. Operation management section 1
1 determines the content delivery rule by comparing and evaluating the characteristic and the user's response history. As shown in FIG. 3A, in the history information DB 116, a past delivery history and a user's reaction history are accumulated by the history storage control unit 111. Here, the message delivery rule DB 117 is searched according to the pattern indicated by the history to obtain message form selection information (step S5).
2).

That is, from the history information DB 116, the behavior pattern of the delivery destination individual (in the case of dunning, whether the user is an addict) or not, and the message delivery rule DB1 is determined according to the pattern.
17 can be searched. Message delivery rule D
The search in B117 is performed by the message selection determining unit 112, and the message DB 118 is accessed based on the message form selection information and the interval information obtained here. Then, an appropriate individual message is assembled (step S53), and the individual message is set in the electronic post-office box 19 to be delivered (step S54). For assembling an individual message, the message assembling control unit 115 specifies a user based on the user ID from a user DB (not shown), and an appropriate message from the message DB 118 based on the message form selection information output from the message selection determining unit 112. This is done by selecting the dunning template. At the time of selecting an individual message in step S53, the timer management unit 114
Similarly, a timer count value obtained from the delivery rule DB 117 is set (step S55).

11 (step S58).

On the other hand, the user receives the pair of the message and the content, and causes an action based on the content and the message (step S59). Here, an online action by a web and an offline action such as a transfer can be considered. On the other hand, if there is no user response, the process waits for a user response (step S6
0). The timer management unit 114 always monitors the timeout of the timer started at the time of content delivery, and when there is a user action within the time, the response history is stored and updated in the history information DB 116 (step S61). . Then, it is determined whether or not the tracking is necessary (step S62). When it is determined that the tracking is necessary, the characteristic of the content and the response history of the user are compared again to evaluate and determine the delivery rule of the content. The processing after step S51 is repeated. On the other hand, if the tracking is not required, the process ends. If a timeout occurs,
The processing after the next individual content delivery instruction in step S51 may be repeated. Here, the timer value is updated according to the message delivery rule DB 117, the user's response is monitored in accordance with the timer value, and an appropriate reminder template is selected from the message DB 118 based on the difference in the state change.

As described above, according to the present invention, an appropriate delivery cycle or message is selected for each individual based on the past delivery history and response history, and the content is delivered. Are stored in a database, and the delivery cycle and message are determined based on a message delivery rule created in advance by roughly classifying the action pattern type. Here, unless the user accesses the Internet or inputs an offline action, it is assumed that the delivery history and the message are continuously determined with reference to the past history, and the content is automatically delivered. In this way, it manages user reactions, changes in external situations, and changes in the status of the content itself using the timer,
The tracking message is automatically distributed according to the situation.
