Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a block diagram of a system for providing advertisements in accordance with an embodiment of the present invention.

The system according to an embodiment of the present invention includes a user terminal 110, an advertisement providing apparatus 100 and an advertiser terminal 120. [

The advertiser requests the advertisement providing apparatus 100 to advertise using the advertiser terminal 120. An advertiser can select an advertisement content, an exposed page, an exposure scheme, a bid amount, etc. to be exposed using the advertiser terminal 120.

The advertisement providing apparatus 100 exposes the advertisements requested by the advertiser to the user terminal 110. The advertisement providing apparatus 100 may group advertisements requested by advertisers according to user characteristics, and then provide customized advertisements according to the characteristics of the users.

The user terminal 110 is provided with an advertisement from the advertisement providing apparatus 100. A customized advertisement may be provided to the user terminal 110 whenever the user terminal 110 accesses the website operated by the advertisement providing apparatus 100. [

2 is a flowchart illustrating an advertisement providing method according to an embodiment of the present invention.

In step s210, the advertisement providing apparatus 100 determines the exposure order of the advertisement for each user group.

First, the advertisement providing apparatus 100 sets one or more user groups according to the user characteristics. According to one embodiment, the advertisement providing apparatus 100 sets a user group based on at least one of a user's age, a user's residence area, a user's job, a user's gender, a user's purchase log, . The purchase log may include the number of times a user has purchased a specific product in the past, a preferred brand, an online site having a high number of visits, a purchase method, a purchase cycle, and the like.

Next, the advertisement providing apparatus 100 determines the exposure order of the advertisements for each of the user groups. Therefore, even if the advertisement is the same, the exposure rank may be different for users belonging to other groups. For example, an ad A has the highest exposure rank for teen users, but the lowest exposure rank for 20 users.

In step s220, the advertisement providing apparatus determines a remaining exposure amount for each of the plurality of advertisements. The remaining exposure amount refers to the number of residual exposures of the advertisement for a predetermined period.

First, the advertisement providing apparatus 100 determines a unit exposure amount, which is the number of times each of a plurality of advertisements is exposed for a predetermined period of time in proportion to a necessary exposure amount indicating a number of times each of the plurality of advertisements should be exposed. The predetermined period may mean a predetermined time interval according to the embodiment, or may denote a predetermined number of times of advertisement exposure. For example, suppose that Advertiser A requests 100 times of advertisement A, and Advertiser B assumes that advertisement B is exposed 50 times, then the necessary exposure amount for advertisement A becomes 100 times, and advertisement B The required amount of exposure is 50 times. Assuming that the unit dose is the number of exposures corresponding to 1/10 of the total exposure of the entire advertisement, the unit dose for advertisement A is 10 times and the unit dose for advertisement B is 5 times.

Next, the advertisement providing apparatus 100 determines the unit exposure amount for each of the plurality of advertisements as the remaining exposure amount. In the above example, the remaining exposure amount for advertisement A is 10 times, and the remaining exposure amount for advertisement B is 5 times.

In step s230, the advertisement providing apparatus selects and exposes one or more of the plurality of advertisements.

First, the advertisement providing apparatus 100 identifies a user group to which a user to which the advertisement is to be exposed belongs. The advertisement providing apparatus 100 can identify a user group to which a user belongs based on at least one of a user's age, a user's residence area, a job of the user, a sex of the user, a purchase log of the user, .

Next, the advertisement providing apparatus 100 exposes one or more advertisements based on the advertisement exposure ranking for the user group to which the user belongs. There are various ways in which the advertisement providing apparatus 100 selects an advertisement to be exposed. Hereinafter, an example of a method for the advertisement providing apparatus 100 to select an advertisement to be exposed will be described. However, the present invention is not limited thereto.

In the first method, the advertisement providing apparatus 100 selects the advertisement having the highest exposure rank for the user group among the advertisements having the remaining exposure amount of '1' or more. If there are a plurality of advertisements having the highest exposure rank, the advertisement providing apparatus can select the advertisement having the largest remaining exposure.

 In the second method, the advertisement providing apparatus 100 selects the advertisement having the highest exposure rank for the user group among the advertisements having the remaining exposure amount of '1' or more. If a plurality of advertisements having the highest exposure rank are present, the advertisement providing apparatus 100 can select a user's favorite advertisement.

In the third method, the advertisement providing apparatus 100 selects the advertisement having the highest exposure rank for the user group among the advertisements having the remaining exposure amount of '1' or more. If there are a plurality of advertisements having the highest exposure rank, the advertisement providing apparatus 100 can select an advertisement to be exposed based on the exposure history of the advertisement. For example, when advertisement A and advertisement B have the same exposure ranking and advertisement A is exposed recently compared to advertisement B, advertisement providing apparatus 100 can select advertisement B.

In step s240, the advertisement providing apparatus 100 adjusts the remaining exposure amount for the exposed advertisement. For example, the advertisement providing apparatus reduces the remaining exposure amount for the exposed advertisement by one. At this time, if there is an advertisement whose residual exposure amount is below 1 threshold (for example, 0), the corresponding advertisement is deleted from the advertisement list. In addition, if the number (or percentage) of advertisements having the remaining exposure amount equal to or less than the first threshold value is equal to or greater than the second threshold value, at least one remaining exposure amount among the plurality of advertisements is initialized to the unit exposure amount. For example, when the remaining exposure amount of all the advertisements included in the list of advertisements exposed in the current unit period becomes 0, the remaining exposure amount of all the advertisements is initialized to the unit exposure amount. However, for ads that are exposed as much as the required exposure, we do not reset the remaining impressions to unit impressions. Advertisements exposed by the required amount of exposure are all satisfied with the advertiser's request, so the advertiser does not need to expose the advertisement until it does not purchase the advertisement again. FIG. 3 is a flowchart illustrating steps s230 and s240 shown in FIG.

At step S310, the advertisement providing apparatus 100 exposes at least one advertisement. The process of selecting the advertisement to be exposed by the advertisement providing apparatus 100 is explained in step s230 of FIG.

In step s320, the advertisement providing apparatus 100 reduces the remaining exposure amount for the exposed advertisement by one.

In step s330, the advertisement providing apparatus 100 determines whether there is an advertisement having a residual exposure of zero. If there is an advertisement having a residual exposure amount of 0, the advertisement providing apparatus 100 performs step s340 to exclude the advertisement from the list of advertisements to be exposed during the current unit period. In this case, the advertisement is no longer exposed until the end of the unit period to which the current time point belongs, but the advertisement may be exposed again during the next unit time period.

In step s350, the advertisement providing apparatus 100 determines whether an advertisement exists in the advertisement list. If the advertisement exists in the advertisement list, step S310 is performed again. Otherwise, step S360 is performed to initialize the remaining exposure amount. In other words, the unit dose for each ad is reset to the remaining exposure. However, ads that are exposed as much as they need and no longer need to be exposed will be excluded from the ad list unless the advertiser requests the ad again.

FIG. 4 illustrates an example of an exposure ranking for each user according to an embodiment of the present invention.

4, the advertisement providing apparatus 100 includes a user group G1 410, a user group G2 420, a user group G3 430, a user group G4 440, a user group G5 450, a user group G6 (460).

For the user group G1 410, the advertisement R and the advertisement M have the highest exposure rank, the advertisement F and the advertisement A are in the middle, and the advertisement K and the advertisement J are the lowest.

For the user group G2 420, the exposure order of the advertisement F and the advertisement M is the highest, and the advertisement A, the advertisement K, the advertisement R, and the advertisement J are intermediate.

For the user group G3 430, the exposure order of the advertisement R, the advertisement K, the advertisement A, the advertisement F, and the advertisement J is intermediate, and the advertisement M is the lowest.

For the user group G4 (440), the exposure order of the advertisement A, the advertisement F and the advertisement K is the highest, the advertisement M and the advertisement R are the middle, and the advertisement K and the advertisement J are the lowest.

For the user group G5 (450), the exposure order of the advertisement K, the advertisement J, and the advertisement R is intermediate, and the exposure order of the advertisement M, the advertisement F, and the advertisement A is lowest.

For the user group G6 (460), the exposure rank of the advertisement J is the highest, and the advertisement R, the advertisement F, and the advertisement M are the middle, and the advertisement A is the lowest.

FIG. 5 illustrates an example of a change of an advertisement list according to an advertisement exposure according to an exemplary embodiment of the present invention.

5, a user belonging to the user group G4 440, the user group G3 430, the user group G4 440, the user group G2 420, and the user group G6 460, It is assumed that the site is accessed sequentially. In FIG. 5, it is assumed that the unit exposure amount is calculated based on the number of times of 21 advertisement exposures.

5A shows an advertisement list in a case where the remaining exposure amount of the advertisement A, the advertisement F, the advertisement J, the advertisement K, the advertisement M, and the advertisement R is set as a unit exposure amount. Referring to FIG. 5A, during the exposure of the 21st advertisement, the advertisement A should be exposed 4 times, the advertisement F 3 times, the advertisement J 3 times, the advertisement K 6 times, the advertisement M 2 times, and the advertisement R 3 times , Which is the unit exposure for each ad and the remaining exposure at the current point in time.

First, a user belonging to the user group G4 440 approaches a site provided by the advertisement providing apparatus 100. [ The advertisement exposure order for the user group G4 (440) is highest for advertisement A, advertisement F, and advertisement K. Accordingly, the advertisement providing apparatus 100 will expose one of the advertisements A, F, and K. Assuming that the advertisement providing apparatus 100 exposes the advertisement with the largest remaining exposure, the advertisement providing apparatus 100 will expose the advertisement K. As the advertisement K is exposed, the remaining exposure amount for the advertisement K will be reduced by 1 as shown in FIG. 5B.

Next, a user belonging to the user group G3 430 accesses a site provided by the advertisement providing apparatus 100. [ The advertisement exposure ranking for the user group G3 (430) is highest for the advertisement R, the advertisement K, the advertisement A, the advertisement F, and the advertisement J. Therefore, the advertisement providing apparatus 100 will expose one of the advertisement R, the advertisement K, the advertisement A, the advertisement F, and the advertisement J. If the remaining exposure is the largest, the advertisement providing apparatus 100 will expose the advertisement K. [ However, if the exposed point of view exposes the oldest advertisement, the advertisement providing apparatus 100 will expose one of the advertisement R, the advertisement A, the advertisement F, and the advertisement J. The advertisement K is exposed immediately before. For convenience of explanation, assuming that the advertisement providing apparatus 100 has exposed the advertisement K, the remaining exposure amount for the advertisement K will be reduced by 1 as shown in FIG. 5C.

Next, a user belonging to the user group G4 440 has approached the site provided by the advertisement providing apparatus 100. The advertisement exposure order for the user group G4 (440) is highest for advertisement A, advertisement F, and advertisement K. Accordingly, the advertisement providing apparatus 100 will expose one of the advertisements A, F, and K. Assuming that the advertisement providing apparatus 100 exposes the advertisement with the largest remaining exposure, the advertisement providing apparatus 100 will expose the advertisement A or the advertisement K. [ Assuming that the advertisement providing apparatus 100 exposes an older advertisement than the advertisement A or the advertisement K, the advertisement providing apparatus 100 will expose the advertisement A. Therefore, the residual exposure amount for advertisement A will be reduced by one as in Fig. 5D.

Conventionally, when the advertisement is exposed by the CPM method, it is impossible to provide customized advertisement for the user since the required exposure amount for the advertisement is guaranteed. In addition, when a customized advertisement is provided, since a connection to a specific user group may be concentrated, only a specific advertisement is exposed intensively. However, in the case of the present invention, the unit exposure amount is determined by dividing the required exposure amount into unit periods while the advertisement is exposed by the CPM method, and the unit exposure amount is determined as the remaining exposure amount for the unit period. Thereafter, a plurality of advertisements are provided in the form of customized advertisements within a unit dose range for a unit period, and when the remaining exposure amounts for a plurality of advertisements are exhausted, the above process is repeated, And the like.

FIG. 6 shows a block diagram of an advertisement providing apparatus 100 according to an embodiment of the present invention.

The advertisement providing apparatus 100 according to an embodiment of the present invention includes an exposure ranking unit 610, a remaining exposure amount determination unit 620, an advertisement exposure unit 630, and a remaining exposure adjustment unit 640.

The exposure ranking unit 610 determines an exposure ranking of a plurality of advertisements for each user group. In addition, the exposure ranking unit 610 may group advertisements having the same exposure ranking into the same group.

The remaining exposure amount determiner 620 calculates a unit exposure amount, which is the number of times each of the plurality of advertisements is exposed during a unit period in proportion to a necessary exposure amount indicating the number of times each of the plurality of advertisements should be exposed. For example, if the required exposure amount for advertisement A is 240 for a day, and the unit time period is 1 hour, the unit exposure amount for advertisement A is 10. As another example, if the required exposure amount for advertisement A is 240, the necessary exposure amount for advertisement B is 120, and the unit period is 12 exposure, the unit exposure amount for advertisement A is 8 (i.e., 12 * 240 / (240 + 120)) and the unit dose for advertisement B is 4 (i.e., 12 * 120 / (240 + 120)). The remaining exposure amount determining unit 620 determines the unit exposure amount as the remaining exposure amount.

The ad exposure unit 630 identifies the user group to which the user to which the advertisement belongs and exposes at least one advertisement based on the exposure rank for the identified user group. The advertisement exposure unit 630 can select an advertisement to be exposed in consideration of an advertisement exposure rank, a user's advertisement preference, a remaining exposure amount, and the like for a user group.

The remaining exposure adjuster 640 adjusts the residual exposure for at least one of the exposed advertisements. If the unit period has elapsed (e. G., There is no advertisement in the list of ads to be exposed during the current unit period), the remaining exposure adjustment unit 640 initializes the remaining exposure amount to the unit exposure amount. However, ads that have all the required impressions are removed from the ad list (i.e., they are not initialized to unit impressions).

The above-described embodiments of the present invention can be embodied in a general-purpose digital computer that can be embodied as a program that can be executed by a computer and operates the program using a computer-readable recording medium.

The computer readable recording medium may be a magnetic storage medium such as a ROM, a floppy disk, a hard disk, etc., an optical reading medium such as a CD-ROM or a DVD and a carrier wave such as the Internet Lt; / RTI > transmission).
