【0010】

In the present invention, a plurality of advertisement data having different amounts of information are prepared for users having different degrees of interest, and classified and registered in the server system together with one or more fields to which the advertisement data belongs.

【0011】

In addition, in the server system, the usage history of network users is accumulated, the fields are extracted from the contents of the data accessed by the users, the number of accesses is taken into consideration, and one field that is statistically frequently used is one. Calculate and accumulate for each user.

【0012】

Since it is considered that the fields that are frequently used are the fields that the users are highly interested in, the degree of matching between the fields that are frequently used by the users and the fields to which the advertisement belongs is calculated, and for the users who have a high degree of matching, the degree of matching is calculated. Expecting high interest in advertising, we will deliver advertising data with a large amount of information. On the other hand, it is expected that users who do not have a high degree of agreement will be less interested in advertising, and will deliver advertising data with a small amount of information.

【0013】

BEST MODE FOR CARRYING OUT THE INVENTION

Next, an embodiment of the present invention will be described with reference to the drawings.

【0014】

Referring to FIG. 1, the personalized advertisement distribution system according to the embodiment of the present invention is composed of a plurality of client systems 10 and a server system 20.

【0015】

Browser 0 of the client system 10 receives a request for acquisition of data arranged on the network from the user at the user interface between the user and the server system 20, and requests the data via the network access mediation unit 1 of the server system 20. Acquires the data and the advertisement that accompanies it, and outputs it to the screen.

【0016】

The server system 20 has a network access mediation unit 1, a matching unit 2, a personal use history DB3, a personal use field DB4, a distribution advertisement DB5, a field extraction unit 6, and an advertisement registration unit 7. Personal usage history DB3 is a database that stores used data for each user among the data on the network. Personal use field DB4 is a database that stores one or more frequently used fields for each user. The distribution advertisement DB5 is a database that stores the advertisement to be distributed as advertisement data of a plurality of information amounts together with one or more fields to which the advertisement belongs. When the network access mediation unit 1 receives the data acquisition request from the browser 0, the network access mediation unit 1 acquires the requested data from the network, accumulates the data in the personal usage history DB3, and then delivers the advertisement from the matching unit 2. Acquire the data, combine the requested data and the advertisement data, and send it to browser 0. The matching unit 2 acquires one or more frequently used field data of the target individual from the personal use field DB4, obtains the degree of matching with the field of the advertisement data accumulated in the distribution advertisement DB5 of that field, and matches. Extract an appropriate amount of advertising data according to the degree. The field extraction unit 6 analyzes the data stored in the personal use history DB3, extracts the field to which the data belongs, and stores it in the personal use field DB4. The advertisement registration unit 7 accumulates advertisement data of a plurality of information amounts input by the advertiser in a common format in the distribution advertisement DB5.

【0017】

There are two phases in the implementation of the service in this system: the registration of advertising data by the advertiser and the request for data acquisition by the network user. Each phase will be described with reference to FIGS. 2 (1) and 2 (2). <Registration of advertising data by advertisers> 1. Advertiser inputs multiple amounts of advertising data in a fixed format along with data from one or more areas to which it belongs (step 31). 2. The advertisement registration unit 7 stores the input advertisement data and field data in the distribution advertisement DB5 (step 32). <When a network user requests data acquisition> 1. The network user makes a data acquisition request using browser 0 (step 41). 2. Network access mediator 1 acquires the requested data from the network (step 42). 3. The network access mediation unit 1 accumulates the acquired data in the personal usage history DB3 (step 43). 4. The following processing is performed at the same time as the accumulation.

【0018】

(a) The field extraction unit 6 analyzes the accumulated data and extracts the field to which it belongs (step 44).

【0019】

(b) The field extraction unit 6 stores the extracted field data in the personal use field DB4 (step 45). 5. The network access mediation unit 1 sends the advertisement data acquisition request to the matching unit 2 (step 46). 6. Matching unit 2 receives the advertisement data acquisition request (step 47). 7. Matching unit 2 acquires one or more frequently used field data of the target individual from the personal use field DB4, and obtains the degree of matching between the field data and the advertisement field accumulated in the distribution advertisement DB5. Appropriate advertising data according to the degree of matching, that is, advertising data with a large amount of information if the degree of matching is high, and advertising data with a small amount of information if the degree of matching is small is extracted (step 48). 8. Matching unit 2 sends the extracted advertisement data to network access mediation unit 1 (step 49). 9. Network access mediator 1 receives the advertising data (step 50). 10. Network access mediator 1 combines the data requested by the user with the advertising data (step 51). 11. Network access mediator 1 sends the combined data to browser 0 (step 52). 12. Browser 0 receives the data (step 53).

【0020】

Next, the distribution of the advertisement data will be specifically described. Here, the data flow is briefly explained using the HTML format as an example.

【0021】

As an example, the advertisement data shall be declared in the following format.

【0022】

Field: $ Field name 1 ($ Belonging to field 1) $ Field name 2 ($ Belonging to field 2) Degree) Target range: $ Range 1, data type; $ type 1 {data value 1} Target range: $ Range 2, data type; $ type 2 {data value 2} In the above format, the following two types of advertising data declarations are actually illustrated.

【0023】

Areas: Telephone (0.6), Communications (0.4) Target range: [0.5, 1], Data type: Image {logo / gif} Scope: [0, 0.5], Data type: Text {<H1> [ABC ABC Co., Ltd.] </ H1>} The logo.gif of the image data example is shown in Fig. 3.

【0024】

On the other hand, as an example, it is assumed that personal use fields are accumulated in the following formats.

【0025】

User ID: $ ID, Field: $ Field 1 ($ Usage frequency 1), $ Field 2 ($ usage) Frequency 2) It is assumed that the following data is accumulated in the personal use field DB4 in the above format.

【0026】

User ID: A, Field: Communication (0.6), Electricity (0.2), ... User ID: B, Field: Entertainment (0.5), Sports (0.3), ... For the advertisement data example given above, the degree of matching of each user is calculated. The field of advertising data "telephone (0.6), communication (0.4)" is similar to the field of use of user A "communication (0.6), electricity (0.2)", and the degree of agreement is determined by some calculation method. It is assumed that 0.7 is calculated (there are various methods for calculating the degree of agreement, but they are not mentioned here). In this case, since it is within the range of "target range: [0.5, 1]" of the advertisement data, the data value (with a large amount of information) of the image is selected.

【0027】

On the other hand, since the fields of user B's "entertainment (0.5), sports (0.3)" are quite different, it is assumed that the degree of agreement is 0. In this case, the data value (which is within the range of "target range: [0, 0.5]" of the advertisement data and has a small amount of text information) is selected.

【0028】

The HTML data finally sent to the user is as follows in the case of user A. <HTML> <HEAD> <TITLE> ABC Home Page </ TITLE> </ HEAD> <BODY BGCOLOR = "# FFFFFF"> <IMG ALT = "ABC Header" SRC = "ABClogo.gif" WIDTH = 557 HEIGHT = 92> <H1> Welcome to the ABC homepage! </ H1> English version is <A href="index.html"> <b> here </ b> </a>. Classic version is <A href="index-j.old.html"> here </a>. <p> The official server of ABC (ABC Co., Ltd.) is <A HREF="http://www.nttinfo.ntt.co.jp/dlij/index J.html"> <b> ABC DYNAMIC LOOP INFORMATION </ b> </a>. <hr> <CENTER> ABC's <A HREF="WHATSNEW/ntt.co.jp-j.html"> domain name change </a> has ended. thank you for your help. <BR> </ CENTER> <hr> <strong> Mirror server <a href="http://www-ntt."> www.ntt.co.jp/ </a> by HTTP accelerator <a href="http://www.ntt.co.jp/"> www.ntt.co.jp/ </a> nttam.com/"> www-ntt.nttam.com </a> Was launched on a trial basis, please try it. </ strong> <HR> Figure 4 shows an example of this displayed on a WWW browser.

【0029】

On the other hand, in the case of user B, it is as follows. <HTML> <HEAD> <TITLE> ABC Home Page </ TITLE> </ HEAD> <BODY BGCOLOR = "# FFFFFF"> <H1> [ABC ABC Co., Ltd.] </ H1> <H1> Welcome to the ABC homepage! </ H1> English version is <A href="index.html"> <b> here </ b> </a>. Classic version is <A href="index-j.old.html"> here </a>. <p> The official server of ABC (ABC Co., Ltd.) is <A HREF="http://www.nttinfo.ntt.co.jp/dlij/index J.html"> <b> ABC DYNAMIC LOOP INFORMATION </ b> </a>. <hr> <CENTER> ABC's <A HREF="WHATSNEW/ntt.co.jp-j.html"> domain name change </a> has ended. thank you for your help. <BR> </ CENTER> <hr> <strong> Mirror server <a href="http://www-ntt."> www.ntt.co.jp/ </a> by HTTP accelerator <a href="http://www.ntt.co.jp/"> www.ntt.co.jp/ </a> nttam.com/"> www-ntt.nttam.com </a> Was launched on a trial basis, please try it. </ strong> <HR> Figure 5 shows an example of this displayed on the WWW browser.

【0030】

In this way, text data (0.4 Kbytes) is transmitted instead of image data (Fig. 3 1.8 Kbytes) to user B, who seems to be less interested, compared to user A, and the amount of communication Will be reduced.

【0031】

The processing of the network access mediation unit 1, the matching unit 2, the field extraction unit 6, and the advertisement registration unit 7 is recorded on a recording medium such as a CD-ROM or FD as an advertisement distribution program for individuals, and is read out by a data processing device. You can also do it.

【0032】

[Effect of the invention]

As described above, the present invention prepares a plurality of advertisements having different amounts of information to be delivered, classifies and registers them together with the fields to which they belong, and uses them in the data on the network. The fields to which the users belong are extracted from all the data used by the users, the fields that are frequently used are statistically calculated for each user, and the fields that are frequently used are considered to be the fields that the users are highly interested in. By delivering advertising data with a large amount of information to users whose fields and fields to which the advertisement belongs more closely, and advertising data with a small amount of information to users who do not match very well, the user's The fields that are frequently used will be calculated, and the advertisement content will be presented according to the degree of matching with the field to which the advertisement belongs. For users who are expected to be highly interested in the advertisement, the amount of information will be For users who are expected to have a large number of advertisements and a greater advertising effect and are expected to have little interest in advertisements, advertisements with a small amount of information will be delivered, reducing the burden on users and reducing the amount of communication. Will be reduced. As a result, the user has a good impression on the advertiser, and the advertising effect is increased.
