The evaluation device is configured to calculate an evaluation value of the advertising effectiveness of each of the first advertisement and the second advertisement using the allocated increment for one or more sections included in the overlapping period.

Description

[Technical field]

[0001] The present disclosure relates to an evaluation device. [Background technology]

[0002] Advertisements are sometimes broadcast on broadcast media such as television and the Internet. Advertisements are broadcast for the purpose of, for example, appealing to consumers to purchase a product or use a service. Advertisements broadcast on broadcast media (hereinafter also simply referred to as advertisements) have the effect of inducing some viewers who watch the advertisement to take a behavior (hereinafter also simply referred to as action) related to the advertisement, such as a behavior corresponding to the appeal purpose. Techniques for measuring the advertising effectiveness, which is the effectiveness of such broadcast advertisements, are known.

[0003] For example, Patent Document 1 discloses an advertisement effectiveness measurement device that measures the effectiveness of an advertisement based on the number of actions of a viewer that are estimated to have been caused by the advertisement. The advertising effectiveness measurement device of Patent Document 1 is configured to allocate the measured advertising effectiveness between an advertisement related to the advertisement that is broadcast immediately after the advertisement is broadcast and the other advertisement. The advertising effectiveness is allocated based on the ratio of the differences between the broadcast time of the advertisement and the occurrence time of the action for each of the advertisement and the other advertisement. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7212707 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in a device such as that disclosed in Patent Document 1, when allocating advertising effectiveness, it was difficult to accurately calculate the advertising effectiveness of broadcast advertisements by simply considering the difference between the broadcast time of each advertisement and the time when an action occurred.

[0006] One aspect of the present disclosure is to improve the accuracy of calculating the advertising effectiveness of a broadcast advertisement. [Means for solving the problem]

[0007] One aspect of the present disclosure is an evaluation device that evaluates the advertising effectiveness of each of a plurality of broadcast advertisements based on an index common to the plurality of advertisements, and includes an acquisition unit, a setting unit, and a calculation unit. The acquisition unit is configured to acquire, for each advertisement, a measurement value of the index in a first period before the advertisement is broadcast and a second period after the advertisement is broadcast. The setting unit is configured to set, for each advertisement, a reference value of the index based on the measurement value of the index in the first period. The calculation unit is configured to calculate, for each advertisement, a total of increments of the measurement value from the reference value in each of a plurality of sections included in the second period as an evaluation value of the advertising effectiveness.

[0008] When the multiple advertisements include a first advertisement and a second advertisement whose second period at least partially overlaps, the calculation unit allocates to each of the first advertisement and the second advertisement an increment in each of one or more sections included in an overlapping period between the first advertisement and the second advertisement among the second period after the broadcast of the first advertisement and the second period after the broadcast of the second advertisement, in a ratio based on a first elapsed time that is the elapsed time from the broadcast of the first advertisement and a second elapsed time that is the elapsed time from the broadcast of the second advertisement, and a time change in the increment in the second period of at least one advertisement among the multiple advertisements, excluding both the first advertisement and the second advertisement. The calculation unit is configured to calculate an evaluation value of the advertising effectiveness of each of the first advertisement and the second advertisement using the allocated increment for one or more sections included in the overlapping period. The second period of at least one advertisement does not overlap with the second periods of both the first advertisement and the second advertisement.

[0009] According to this configuration, it is possible to calculate an evaluation value of the advertising effectiveness of each of the plurality of advertisements based on the elapsed time from the broadcast of each of the advertisements, thereby improving the accuracy of calculating the advertising effectiveness of the broadcasted advertisements.

[0010] In one aspect of the present disclosure, the calculation unit may determine, for each of one or more sections in the overlapping period, a first contribution degree, which is a degree by which the first advertisement contributes to the magnitude of the increment, and a second contribution degree, which is a degree by which the second advertisement contributes to the magnitude of the increment, for an increment in a corresponding section, based on the first elapsed time and the second elapsed time and a time change in the increment of at least one advertisement. The calculation unit may be configured to allocate the increment to the first advertisement and the second advertisement based on a ratio of the first contribution degree and the second contribution degree.

[0011] According to this configuration, it is possible to calculate the evaluation value of the advertising effectiveness of each of the multiple advertisements based on the ratio of the degree to which each of the advertisements contributes to the magnitude of the increase, thereby improving the accuracy of calculating the advertising effectiveness.

[0012] In one aspect of the present disclosure, the calculation unit may calculate a first reference degree of contribution based on a first elapsed time and a time change in an increment of at least one advertisement. The calculation unit may calculate a second reference degree of contribution based on a second elapsed time and a time change in an increment of at least one advertisement. The calculation unit may calculate the first degree of contribution by correcting the first reference degree of contribution based on the viewing amount of the first advertisement. The calculation unit may calculate the second degree of contribution by correcting the second reference degree of contribution based on the viewing amount of the second advertisement.

[0013] According to this configuration, the first contribution degree and the second contribution degree can be calculated taking into account the viewing amount of the first advertisement and the second advertisement, thereby improving the accuracy of calculating the advertising effect.

[0014] In one aspect of the present disclosure, the calculation unit may calculate the first contribution degree by further correcting the first reference contribution degree based on an area coverage rate of the first advertisement. The calculation unit may be configured to calculate the second contribution degree by further correcting the second reference contribution degree based on an area coverage rate of the second advertisement. The area coverage rate may be a ratio of households to which the advertisement is broadcast in a specified area to all households in the specified area.

[0015] According to this configuration, it is possible to calculate the evaluation value of the advertising effectiveness of each of the first advertisement and the second advertisement by taking into account the area coverage rates of the first advertisement and the second advertisement, thereby improving the accuracy of calculating the advertising effectiveness.

[0016] In one aspect of the present disclosure, the predetermined area may be an area that is predefined on a prefecture-by-prefecture basis. In one embodiment of the present disclosure, the first contribution degree may be calculated as a product of the first reference contribution degree, the viewing amount of the first advertisement, and the area coverage rate of the first advertisement. The second contribution degree may be calculated as a product of the second reference contribution degree, the viewing amount of the second advertisement, and the area coverage rate of the second advertisement.

[0017] According to this configuration, the first and second reference contribution rates can be calculated taking into account the viewing amounts and area coverage rates of the first and second advertisements, thereby improving the accuracy of calculating the advertising effectiveness.

[0018] In one aspect of the present disclosure, for each of one or more intervals in the overlapping period, each of the first base contribution and the second base contribution may be calculated based on an increment in the corresponding interval of the second period of at least one advertisement.

[0019] In one aspect of the present disclosure, the at least one advertisement may include two or more advertisements. For each of the one or more intervals in the overlapping period, each of the first base contribution and the second base contribution may be calculated by summing the increments of the two or more advertisements in the corresponding intervals.

[0020] According to this configuration, the evaluation value of the advertising effectiveness can be calculated based on the increments in the other advertisements, thereby improving the accuracy of calculating the advertising effectiveness. In one aspect of the present disclosure, the second period after the broadcast of the advertisement may be set based on a measurement value during a first period before the broadcast of the advertisement and a measurement value after the broadcast of the advertisement.

[0021] In one aspect of the present disclosure, the second period after the broadcast of the advertisement may be set based on the difference between the average value of the measurement value during the first period before the broadcast of the advertisement and the measurement value after the broadcast of the advertisement. In one aspect of the present disclosure, the second period after the advertisement is broadcast may be set based on the period from the start time of the advertisement being broadcast to the time when the measurement value of the advertisement's index reaches a maximum and then the difference disappears.

[0022] According to this configuration, the second period can be set based on the measurement value of the first period, which improves the accuracy of calculating the advertising effect. In one aspect of the present disclosure, the reference value may be set based on an average value of the measurement values ​​in the first period.

[0023] According to this configuration, the increment of the measurement value can be calculated based on the average value of the measurement value in the first period, which improves the accuracy of calculating the advertising effect. In one aspect of the present disclosure, the setting unit may be configured to set the reference value of the fourth advertisement to the same value as the reference value of the third advertisement when the multiple advertisements include a third advertisement and a fourth advertisement, where a first period of the fourth advertisement broadcast after the third advertisement has a period that overlaps with a second period of the third advertisement.

[0024] According to this configuration, the reference value can be calculated based on the first period that does not include a period that overlaps with the second period of another advertisement, thereby improving the accuracy of calculating the advertising effectiveness of the broadcasted advertisement.

[0025] In one aspect of the present disclosure, the at least one advertisement may be one or more advertisements that aired earlier than both the first advertisement and the second advertisement. According to this configuration, the increments in one or more sections included in the overlapping period can be allocated to each of the first and second advertisements based on the time change in the increments in the second period of past advertisements that are not affected by the advertising effects of the first and second advertisements, thereby improving the accuracy of calculating the advertising effects.

[0026] In one aspect of the disclosure, the second time period of each of the at least one advertisement may not overlap with the second time periods of any other advertisements of the plurality of advertisements. According to this configuration, the increments in one or more sections included in the overlapping period can be allocated to each of the first and second advertisements based on the time change in the increments in the second period of the advertisement in which the influence of the advertising effect of the other advertisements is suppressed, thereby improving the accuracy of calculating the advertising effect.

[0027] One aspect of the present disclosure is an evaluation method for evaluating the advertising effectiveness of each of a plurality of broadcast advertisements based on an index common to the plurality of advertisements, the method including: a computer acquiring, for each advertisement, measurement values ​​of the index for a first period before the advertisement is broadcast and a second period after the advertisement is broadcast; setting, for each advertisement, a reference value of the index based on the measurement value of the index in the first period; and calculating, for each advertisement, the sum of increments of the measurement values ​​from the reference value in each of a plurality of sections included in the second period as an evaluation value of the advertising effectiveness. The calculating includes, when the multiple advertisements include a first advertisement and a second advertisement whose second period at least partially overlaps, allocating to each of the first advertisement and the second advertisement an increment in each of one or more sections included in an overlapping period between the first advertisement and the second advertisement among the second period after the broadcast of the first advertisement and the second period after the broadcast of the second advertisement, in a ratio based on a first elapsed time that is the elapsed time from the broadcast of the first advertisement and a second elapsed time that is the elapsed time from the broadcast of the second advertisement, and a time change in an increment in the second period of at least one advertisement among the multiple advertisements, excluding both the first advertisement and the second advertisement. The calculating also includes calculating an evaluation value of the advertising effectiveness of each of the first advertisement and the second advertisement using the allocated increment for one or more sections included in the overlapping period. The second period of at least one advertisement does not overlap with the second periods of both the first advertisement and the second advertisement.

[0028] This evaluation method provides the same effects as the above-mentioned evaluation device. In one aspect of the present disclosure, a computer program may be provided for causing a computer to execute, at least in part, the above-described evaluation method.

[0030] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. First embodiment] [1-1. Configuration] [1-1-1. Overall composition] 1 is a device that evaluates the advertising effectiveness of advertisements broadcast on broadcast media such as television, the Internet, etc. The evaluation device 1 is installed in an information terminal such as a smartphone, a tablet terminal, or a personal computer.

[0031] The evaluation device 1 includes a processor 10, a memory 20, a storage 30, a user interface 40, and a communication interface 50. The processor 10 is configured to execute processing in accordance with a computer program recorded in the storage 30 .

[0032] The memory 20 is used as a working area when the processor 10 executes processing. Examples of the memory 20 include a random access memory (RAM), a read only memory (ROM), and a flash memory.

[0033] The storage 30 records computer programs and data used when executing processes according to the computer programs. Examples of the storage 30 in a smartphone, tablet terminal, etc. include eMMC (embedded multi media card), UFS (universal flash storage), etc. Examples of the storage 30 in a personal computer include HDD (hard disk drive), SSD (solid state drive), etc.

[0034] The user interface 40 is a general term for an interface for receiving various input operations from a user and an interface for outputting various information to the user. Examples of the user interface 40 include a keyboard, a mouse, a touch panel, a display, etc.

[0035] The communication interface 50 is an interface capable of communicating various types of data with other devices in accordance with a predetermined standard. [1-1-2. Advertising effectiveness] As shown in FIG. 2, for one advertisement, an evaluation value V of the advertising effectiveness due to the broadcast of the advertisement is calculated based on the measurement value M of a predetermined evaluation index measured in a predetermined period including the period before and after the broadcast. To calculate the evaluation value V, a reference value BL is set based on the measurement value M of the evaluation index in the period before the advertisement is broadcast. The reference value BL is set for each advertisement. The evaluation value V of the advertising effectiveness is calculated as the sum of the increments of the measurement value M from the reference value BL in the period after the advertisement is broadcast. Hereinafter, the measurement value M of the evaluation index is also simply referred to as the measurement value M. The evaluation value V of the advertising effectiveness is also simply referred to as the evaluation value V.

[0036] The evaluation index is an index related to the advertising effectiveness. The advertising effectiveness of each of a plurality of advertisements is evaluated based on an evaluation index common to the plurality of advertisements. The evaluation index can be expressed, for example, by quantifying the magnitude of consumer behavior regarding a product or service promoted by the advertisement. Examples of the evaluation index include the number of visits to a website related to the product or service promoted by the advertisement, the number of PV (Page Views), the number of app downloads, the number of searches by search engines, etc.

[0037] The predetermined period includes a reference period BT and a valid period ET. The validity period ET is a period after the advertisement is broadcast. The validity period ET represents a period during which the advertisement effect is valid. The period during which the advertisement effect is valid may be understood as a period during which the advertisement effect continues. For example, if the validity period ET is set to 10 minutes, this means that the advertisement effect lasts for 10 minutes after the advertisement is broadcast. In this embodiment, as an example, the validity period ET is set to 10 minutes, but the validity period ET is not limited to 10 minutes and may take other values. For example, the validity period ET may be set to 20 minutes.

[0038] The valid period ET includes a plurality of intervals. The plurality of intervals are defined by dividing the valid period ET. The length of each interval is not particularly limited, but in this embodiment, as an example, the valid period ET is divided into a total of ten intervals S1 to S10, each of which is one minute.

[0039] Section S1 is the section from 0 to 1 minute after the advertisement is broadcast (in other words, the first minute after the advertisement is broadcast). Section S2 is the section from 1 to 2 minutes after the advertisement is broadcast (in other words, the next minute after section S1). Similarly, for an integer i from 1 to 10, section Si is the section from (i-1) minutes to i minutes after the advertisement is broadcast (in other words, the next minute after section S(i-1)).

[0040] The reference period BT is a period before the broadcast of an advertisement. The reference period BT is a period during which the advertising effect of the broadcast of the advertisement does not extend. In the present embodiment, as an example, the length of the reference period BT is the same as the length of the effective period ET. However, the length of the reference period BT may be different from the length of the effective period ET.

[0041] The reference value BL is the sum of the measurement values ​​M in the reference period BT divided by the length of the reference period BT. In other words, the reference value BL is the average value of the measurement values ​​M in the reference period BT. As shown in FIG. 3, the evaluation value V of the valid period ET is the sum of the increments L of the measurement value M from the reference value BL in each of the multiple sections included in the valid period ET. The increment L in each section is the difference between the measurement value M in each section and the reference value BL. However, in a section in which the measurement value M is smaller than the reference value BL, the increment L is not a negative value but is instead zero. In this embodiment, as an example, the increment L in the section Si is referred to as the increment Li. The evaluation value V of the advertising effect is expressed by the sum of the increments Li in multiple sections. When the period of the evaluation value V is not specified below, the evaluation value V may be understood to be the evaluation value V of the valid period ET. When the period of the evaluation value V is specified, the evaluation value V corresponds to the integral value of the increment in the specified period. As described above, when the increment L in the valid period ET is expressed as a discrete value for each section, the integral value of the difference between the measurement value M and the reference value BL corresponds to the sum of the increments L for each section in the period.

[0042] 3, the reference value BL is 2.1. The measured value M in the section S2 is 7, and the increment L2 in the section S2 is 4.9, which is the difference between the measured value M and the reference value BL.

[0043] On the other hand, the measured value M in section S5 is "1", and the difference between the measured value M and the reference value BL is a negative value "-1.1", so the increment L5 is "0.0". When advertisements whose advertising effectiveness is evaluated based on a common evaluation index are broadcast multiple times in a short period of time, the reference value BL of each of the multiple advertisements is, for an advertising broadcast having a reference period BT that does not include a period overlapping with the effective period ET of another advertising broadcast among the multiple advertising broadcasts, the total value of the measurement value M during the reference period BT of that advertising broadcast is divided by the length of the reference period BT.

[0044] For example, as shown in Fig. 4, a case will be considered in which a first advertisement 60 and a second advertisement 70 are broadcast after the first advertisement 60. The advertising effectiveness of the first advertisement 60 and the second advertisement 70 is evaluated based on a common evaluation index.

[0045] In this case, the reference period BT1 of the first advertisement 60 does not include a period overlapping with the validity period ET2 of the second advertisement 70. On the other hand, the reference period BT2 of the second advertisement 70 includes a period overlapping with the validity period ET1 of the first advertisement 60. Therefore, the reference value BL of the first advertisement 60 and the reference value BL of the second advertisement 70 are both the sum of the measurement values ​​M in the reference period BT1 divided by the length of the reference period BT1. In other words, the reference value BL of the first advertisement 60 is also set as the reference value BL of the second advertisement 70.

[0046] When an advertisement is broadcast in a plurality of broadcast areas, the reference value BL is set for each of the broadcast areas. Examples of the broadcast area include a region such as Kanto or Tokai, or a prefecture such as Tokyo or Kanagawa.

[0047] [1-2. Processing] Below, a series of processes executed by the processor 10 to calculate the advertising effectiveness of each advertisement when a second advertisement 70 is broadcast immediately after a first advertisement 60 is broadcast will be described with reference to the flowchart of Figure 5, Figures 6, 7 and 8.

[0048] The first advertisement 60 and the second advertisement 70 are advertisements that are broadcast in the same broadcast area in the same campaign. The advertising effectiveness of the first advertisement 60 and the second advertisement 70 is evaluated based on a common evaluation index. The contents of the first advertisement 60 and the second advertisement 70 may be the same or different. The broadcast times of the first advertisement 60 and the second advertisement 70 are different from each other.

[0049] When an instruction is input from the user via the user interface 40, the processor 10 starts the process shown in FIG. First, in S100, the processor 10 acquires advertisement information of the first advertisement 60 and the second advertisement 70. The advertisement information includes the advertisement broadcast time, the viewing amount P, the broadcasting media company, the broadcast area, and the area coverage rate C. The processor 10 may acquire the advertisement information stored in the storage 30 in advance, or may acquire the advertisement information from outside the evaluation device 1 via the communication interface 50.

[0050] The viewing amount P represents a viewing rate or a parameter related to the viewing rate. The viewing rate is a real-time viewing rate and does not include a time-shifted viewing rate. The viewing amount P may be, for example, a GRP (Gross Rating Point) representing a total viewing rate by household, or a TRP (Target Rating Point) representing a total viewing rate by individual.

[0051] The area coverage rate C is the ratio of households to which an advertisement is broadcast in a specified area to all households in the specified area. In the present embodiment, as an example, the area coverage rate C is the ratio of households to which an advertisement is broadcast by a target media company to the total number of households in a target prefecture. For example, when a target media company broadcasts an advertisement to all households in Tokyo, the area coverage rate C for Tokyo is 100%.

[0052] FIG. 6 shows an example of the advertisement information of the first advertisement 60 and the second advertisement 70. In FIG. For the first advertisement 60, the broadcast time is "09:00." The first viewer amount Pa of the first advertisement 60 is "4.3." The media company is "XXX Station." The broadcast area is "Tokai." The first area coverage rate Ca of the first advertisement 60 is "100%" in all of Aichi, Gifu, and Mie.

[0053] For the second advertisement 70, the broadcast time is "09:07." The second viewership Pb of the second advertisement 70 is "3.1." The media company is "YYY Station." The broadcast area is "Tokai." Regarding the second area coverage rate Cb of the second advertisement 70, Aichi is "100%." ​​Gifu is "80%." Mie is "90%."

[0054] Next, in S102, the processor 10 acquires a measurement value M of an evaluation index related to the advertising effectiveness of the first advertisement 60 and the second advertisement 70 during a campaign period in which the advertisements are broadcast. The processor 10 may acquire the measurement value M of the evaluation index stored in advance in the storage 30, or may acquire the measurement value M of the evaluation index from outside the evaluation device 1 via the communication interface 50.

[0055] The measured value M of the evaluation index represents the measured value M at every fixed time during the campaign period. For example, the processor 10 acquires the measured value M of the evaluation index for every minute from the start of the campaign period. The measured value M is, for example, the number of website visits, the number of page views, the number of app downloads, or the number of searches by a search engine during one minute. In FIG. 6, the progress of the measured value M of the evaluation index over time is shown by a solid line.

[0056] Next, in S104, the processor 10 sets the valid period ET and the reference period BT to predetermined values. In the present embodiment, as an example, the valid period ET is set to 10 minutes. That is, the valid period ET1 of the first advertisement 60 and the valid period ET2 of the second advertisement 70 are both set to 10 minutes.

[0057] In the present embodiment, as an example, the reference period BT is set to the same value as the valid period ET. That is, the reference period BT1 of the first advertisement 60 and the reference period BT2 of the second advertisement 70 are both set to 10 minutes.

[0058] Next, in S106, the processor 10 sets the reference value BL for each of the first advertisement 60 and the second advertisement 70. In this embodiment, the second advertisement 70 is broadcast after the first advertisement 60 is broadcast. The reference period BT1 of the first advertisement 60 does not include a period that overlaps with the validity period ET2 of the second advertisement 70. On the other hand, the reference period BT2 of the second advertisement 70 includes a period that overlaps with the validity period ET1 of the first advertisement 60. Therefore, the reference value BL of the first advertisement 60 is also set as the reference value BL of the second advertisement 70.

[0059] The processor 10 sets the sum of the measurement values ​​M in the reference period BT1 divided by the length of the reference period BT1 as the reference value BL of the first advertisement 60 and the second advertisement 70. In other words, the reference value BL is the average value of the measurement values ​​M in the reference period BT1.

[0060] Next, in S108, the processor 10 determines whether or not there is a non-overlapping period NT that is a period that does not overlap with the validity period ET of another advertisement, among the validity periods ET of the first advertisement 60 and the second advertisement 70. If the processor 10 determines in S108 that there is no non-overlapping period NT (S108: NO), it skips S110 and proceeds to S112.

[0061] On the other hand, when the processor 10 determines in S108 that there is a non-overlapping period NT (S108: YES), the processor 10 proceeds to S110 and calculates an evaluation value V of the advertising effectiveness of each of the first advertisement 60 and the second advertisement 70 in the non-overlapping period NT. That is, the advertising effectiveness of the first advertisement 60 in the non-overlapping period NT1 of the valid period ET1 is the evaluation value V in the non-overlapping period NT1. The advertising effectiveness of the second advertisement 70 in the non-overlapping period NT2 of the valid period ET2 is the evaluation value V in the non-overlapping period NT2.

[0062] Specifically, the processor 10 calculates an evaluation value V in the non-overlapping period NT for each broadcast area. The processor 10 calculates the sum of the evaluation values ​​V in the non-overlapping period NT of all broadcast areas as the evaluation value V in the non-overlapping period NT.

[0063] 6, the validity period ET1 of the first advertisement 60 is 10 minutes from "9:00" to "9:10." The validity period ET2 of the second advertisement 70 is 10 minutes from "9:07" to "9:17."

[0064] That is, the first advertisement 60 has a non-overlapping period NT1 from "9:00" to "9:07." The second advertisement 70 has a non-overlapping period NT2 from "9:10" to "9:17."

[0065] Therefore, the evaluation value V of the first advertisement 60 in the non-overlapping period NT1 is the sum of the increments L for each section in the period from "9:00" to "9:07", totaled for all broadcast areas. Similarly, the evaluation value V of the second advertisement 70 in the non-overlapping period NT2 is the sum of the increments L for each section in the period from "9:10" to "9:17", totaled for all broadcast areas.

[0066] Next, in S112, the processor 10 determines whether or not there is an overlapping period OT, which is a period that overlaps with the validity period ET of another advertisement, among the respective validity periods ET of the first advertisement 60 and the second advertisement 70. If the processor 10 determines in S112 that there is no overlapping period OT (S112: NO), it outputs the evaluation value V of the non-overlapping period NT1 as the evaluation value V of the advertising effectiveness in the validity period ET1 of the first advertisement 60. Furthermore, the processor 10 outputs the evaluation value V of the non-overlapping period NT2 as the evaluation value V of the advertising effectiveness in the validity period ET2 of the second advertisement 70. Thereafter, the processing of FIG. 5 ends.

[0067] On the other hand, when the processor 10 determines in S112 that there is an overlapping period OT (S112: YES), the processor 10 proceeds to S114. In this embodiment, the other advertisement whose validity period ET overlaps with that of the first advertisement 60 is the second advertisement 70. Similarly, the other advertisement whose validity period ET overlaps with that of the second advertisement 70 is the first advertisement 60.

[0068] The processor 10 calculates an evaluation value V for each broadcast area in the overlap period OT. At this stage, the evaluation value V reflects the advertising effectiveness of both the first advertisement 60 and the second advertisement 70.

[0069] In this embodiment, the broadcast area of ​​both the first advertisement 60 and the second advertisement 70 is "Tokai." The broadcast area "Tokai" includes the prefectures "Aichi," "Gifu," and "Mie." Therefore, the processor 10 calculates the evaluation value V for each of "Aichi," "Gifu," and "Mie" during the overlapping period OT. FIG. 7 shows the evaluation values ​​V for each of "Aichi," "Gifu," and "Mie" during the period from "9:07" to "9:10," which corresponds to the overlapping period OT.

[0070] Next, in S116, the processor 10 determines the reference contribution degree W of the first advertisement 60 and the second advertisement 70. The reference contribution degree W is determined for each campaign. That is, the reference contribution degree W of the first advertisement 60 and the reference contribution degree W of the second advertisement 70 are the same.

[0071] As shown in FIG. 8, the reference contribution degree W is determined for each section of the valid period ET divided into a plurality of sections. In other words, the reference contribution degree W is determined based on the elapsed time from the broadcast of the advertisement. In the present embodiment, as an example, the valid period ET is divided into 1-minute intervals. The i-th (i is an integer equal to or greater than 1) section Si among the multiple sections in the valid period ET is a section from (i-1) minutes to i minutes. Specifically, the first section S1 is a section from 0 minutes to 1 minute, and the second section S2 is a section from 1 minute to 2 minutes. For example, when the valid period ET is 10 minutes, the valid period ET is divided into a total of 10 sections S1 to S10, each divided into 1 minute.

[0072] The reference contribution degree W is determined based on a time change in an increment L in the validity period ET of at least one advertisement, excluding both the first advertisement 60 and the second advertisement 70, among a plurality of advertisements broadcast during the campaign period. In this embodiment, the reference contribution degree W is determined for each section for one or more advertisements broadcast earlier than both the first advertisement 60 and the second advertisement 70, based on an increment L for each section included in the validity period ET of each advertisement.

[0073] For example, if an advertisement related to the campaign has been broadcast three times during the campaign period prior to the first advertisement 60, the reference contribution Wi corresponding to the section Si is the sum of the increments Li of the section Si in each of the three broadcasts. The reference contribution Wi may be the sum of the increments Li of the section Si in each of the three broadcasts divided by the number of broadcasts (i.e., the average value).

[0074] However, a broadcast time during the campaign period in which the effective period ET of at least one advertisement does not overlap with an overlapping period OT is used as the broadcast time of at least one advertisement used to determine the reference contribution degree W (hereinafter, referred to as the determining broadcast time). In other words, the effective period ET of at least one advertisement does not overlap with the effective periods ET of at least both the first advertisement 60 and the second advertisement 70.

[0075] If there are no broadcasts without overlapping OTs during the campaign period, the broadcasts of multiple advertisements that were broadcast at the same time will be used as the deciding broadcast. Specifically, multiple advertisements that have the same broadcasting time and start within one minute of each other will be considered as broadcasts that were broadcast at the same time and will be used as the deciding broadcast.

[0076] If there are no multiple advertisement episodes aired at the same time during the campaign period, multiple broadcast episodes will be used as deciding episodes, with one randomly selected per day. 8 shows the reference contribution degree W in each of the sections S1 to S10 determined by the above-mentioned process. For example, the reference contribution degree W2 in the section S2 is "2000".

[0077] Next, at S118, the processor 10 calculates the evaluation value V of each of the first advertisement 60 and the second advertisement 70 in the overlapping period OT by allocating an increment L based on the ratio between the first contribution degree Ta of the first advertisement 60 and the second contribution degree Tb of the second advertisement 70 corresponding to each section included in the overlapping period OT.

[0078] The first contribution degree Ta is the degree to which the first advertisement 60 contributes to the magnitude of the increment L. The first contribution degree Ta is determined based on the first reference contribution degree Wa of the first advertisement 60 corresponding to the target section, the first viewing amount Pa of the first advertisement 60, and the first area coverage rate Ca of the first advertisement 60. In this embodiment, the first contribution degree Ta is the product of the first reference contribution degree Wa, the first viewing amount Pa, and the first area coverage rate Ca.

[0079] The second contribution degree Tb is the degree to which the second advertisement 70 contributes to the magnitude of the increment L. The second contribution degree Tb is determined based on the second reference contribution degree Wb of the second advertisement 70 corresponding to the target section, the second viewing amount Pb of the second advertisement 70, and the second area coverage rate Cb of the second advertisement 70. In this embodiment, the second contribution degree Tb is the product of the second reference contribution degree Wb, the second viewing amount Pb, and the second area coverage rate Cb.

[0080] Therefore, the first contribution degree Ta and the second contribution degree Tb can be determined by the following equations (1) and (2).

[0083] As an example, a method of allocating the increase Lg for the Gifu area in the section from "9:08" to "9:09" in FIG. 7 to the increase Lga of the first advertisement 60 and the increase Lgb of the second advertisement 70 will be described below.

[0084] For the section from "9:08" to "9:09", the elapsed time from 8 minutes to 9 minutes since the broadcast of the first advertisement 60 is completed. Therefore, the first reference contribution degree Wa of the first advertisement 60 for this section is "400", which corresponds to the reference contribution degree W of "8-9 minutes" in FIG.

[0085] 8. Similarly, the elapsed time from the broadcast of the second advertisement 70 is from 1 minute to 2 minutes. Therefore, the second reference contribution degree Wb of the second advertisement 70 in this section is “2000”, which corresponds to the reference contribution degree W of “1-2 minutes” in FIG.

[0086] The first viewing amount Pa, the first area coverage rate Ca, the second viewing amount Pb, and the second area coverage rate Cb are acquired in S100. According to FIG. 6, the first viewing amount Pa is "4.3". The first area coverage rate Ca is "100%". The second viewing amount Pb is "3.1". The second area coverage rate Cb is "80%". According to FIG. 7, the increment Lg of the Gifu area in the section from "9:08" to "9:09" is "60".

[0087] When these values ​​and the values ​​of the first reference contribution degree Wa and the second reference contribution degree Wb are used, the increment Lga of the first advertisement 60 is "15.4" according to the following formula (3). The increment Lgb of the second advertisement 70 is "44.6" according to the following formula (4). In other words, the increment Lg "60" of the Gifu area in the section from "9:08" to "9:09" is allocated to the increment Lga of the first advertisement 60 of "15.4" and the increment Lgb of the second advertisement 70 of "44.6" based on the ratio of the first contribution degree Ta and the second contribution degree Tb.

[0090] By performing the above-mentioned process for each section included in the overlapping period OT, the increment L for each section can be allocated between the first advertisement 60 and the second advertisement 70. Then, the processor 10 ends the process of FIG.

[0091] In this manner, the processor 10 allocates the increment L based on the ratio between the first contribution Ta of the first advertisement 60 and the second contribution Tb of the second advertisement 70 corresponding to each section included in the overlap period OT.

[0092] [1-3. Effects] According to the embodiment described above, the following actions and effects can be obtained. (1a) For the first advertisement 60 and the second advertisement 70, when there is an overlapping period OT, which is a period that overlaps with the validity period ET of another advertisement, among the respective effective periods ET, for each of one or more sections in the overlapping period OT, the increment L for each section is calculated by allocating based on the ratio between the first contribution degree Ta of the first advertisement 60 and the second contribution degree Tb of the second advertisement 70. The evaluation value V of the advertising effectiveness of each of the first advertisement 60 and the second advertisement 70 in the overlapping period OT is calculated by summing up the increments L of the first advertisement 60 and the second advertisement 70 allocated in each section.

[0093] The first contribution degree Ta is determined based on the first reference contribution degree Wa. The second contribution degree Tb is determined based on the second reference contribution degree Wb. The first reference contribution degree Wa and the second reference contribution degree Wb are determined based on a time change in an increment L in an effective period ET of at least one advertisement, excluding both the first advertisement 60 and the second advertisement 70, among a plurality of advertisements broadcast during the campaign period.

[0094] According to this process, the increment L of each of the first advertisement 60 and the second advertisement 70 in each section during the overlapping period OT is assigned by weighting based on the performance value of the increment L of other advertisements broadcast during the campaign period. This improves the accuracy of calculating the advertising effectiveness of the broadcasted advertisements.

[0095] (1b) A reference contribution degree W corresponding to an i-th section (i is an integer equal to or greater than 1) among a plurality of sections is determined based on the total value of the increments L of the i-th section in at least one broadcast episode.

[0096] According to this process, the difference in advertising effectiveness caused by the difference in the elapsed time since the advertisement was broadcast can be reduced, and therefore a more appropriate reference contribution degree W can be determined. (1c) As the broadcast episode of at least one advertisement used to determine the standard contribution degree W (in other words, the broadcast episode for determination), a broadcast episode that does not have an overlapping period OT with the effective period ET of the broadcast during the campaign period is used.

[0097] Such a deciding broadcast time is less susceptible to the advertising effectiveness of other advertisements, and therefore it is possible to determine a more appropriate standard contribution degree W than by including the broadcast time of an advertisement in the effective period ET that has an overlapping period OT.

[0098] If there is no broadcast episode without overlapping OT during the campaign period, the broadcast episodes of multiple advertisements that were broadcast at the same time will be used as the deciding broadcast episode. Such a deciding broadcast time can reduce the difference in advertising effectiveness caused by the difference in the time at which a plurality of advertisements are broadcast, and therefore a more appropriate reference contribution degree W can be determined.

[0099] If there are no multiple advertisement episodes aired at the same time during the campaign period, multiple broadcast episodes will be used as deciding episodes, with one randomly selected per day. According to such a process, bias in the deciding broadcast times is suppressed, so that an appropriate reference contribution degree W can be determined.

[0100] (1d) The increment L is the difference between the measurement value M of the evaluation index and the reference value BL in each of the multiple sections included in the effective period ET. The reference value BL is the average value of the measurement value M in the reference period BT. The reference period BT is a period before the broadcast of an advertisement, and therefore is a period during which the advertising effect of the broadcast of the advertisement does not extend.

[0101] According to such a configuration, the degree to which the evaluation index has increased due to the broadcast of the advertisement compared to before the advertisement was broadcast can be calculated as the increment L. Therefore, the evaluation value V of the advertising effectiveness can be calculated based on the increment L.

[0102] 4, when a second advertisement 70 is broadcast after a first advertisement 60, the reference value BL of the first advertisement 60 and the reference value BL of the second advertisement 70 are both calculated by dividing the total value of the measurement value M in the reference period BT1 of the first advertisement 60 by the length of the reference period BT1. In other words, the reference value BL of the first advertisement 60 is also set as the reference value BL of the second advertisement 70.

[0103] According to this process, the reference value BL of each advertisement is calculated based on the reference period BT that does not include a period overlapping with the effective period ET of other advertisements, thereby improving the accuracy of calculating the advertising effectiveness of the broadcasted advertisements.

[0104] (1f) The first contribution Ta is the product of the first reference contribution Wa, the first viewing amount Pa, and the first area coverage rate Ca. The second contribution Tb is the product of the second reference contribution Wb, the second viewing amount Pb, and the second area coverage rate Cb.

[0105] The evaluation value V of the advertising effectiveness of each of the first advertisement 60 and the second advertisement 70 during the overlapping period OT is calculated by allocating the increment L corresponding to each section included in the overlapping period OT based on the ratio between the first contribution degree Ta of the first advertisement 60 and the second contribution degree Tb of the second advertisement 70.

[0106] According to such a process, the advertising effectiveness can be allocated by weighting based on the actual values ​​of the viewing amount P and the area coverage rate C. This makes it possible to improve the accuracy of calculating the advertising effectiveness of the broadcasted advertisement.

[0107] [1-4. Correspondence between terms] In the above embodiment, the evaluation index corresponds to an example of an index common to a plurality of advertisements, the reference period BT corresponds to an example of a first period, and the valid period ET corresponds to an example of a second period. The first advertisement 60 corresponds to an example of a third advertisement, and the second advertisement 70 broadcast after the broadcast of the first advertisement 60 corresponds to an example of a fourth advertisement.

[0108] The process of S102 corresponds to an example of a process executed as an acquisition unit, the process of S106 corresponds to an example of a process executed as a setting unit, and the processes from S110 to S118 correspond to an example of a process executed as a calculation unit.

[0109] 2. Other embodiments Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above-described embodiments and can take various forms.

[0110] (2a) In the above embodiment, the validity period ET is set to 10 minutes in S104. However, the validity period ET may be set to a value other than 10 minutes, or may be set by another method. After being set in S104, the validity period ET may be reset by another method.

[0111] For example, the validity period ET may be set based on a measurement value M during a predetermined period before the advertisement is broadcast and a measurement value M after the advertisement is broadcast. Specifically, after a reference value BL is set, the validity period ET may be set based on a difference between the measurement value M after the advertisement is broadcast and the reference value BL.

[0112] Alternatively, the validity period ET may be set based on the period from the start time of the advertisement's broadcast to the time when the difference between the measurement value M after the advertisement is broadcast and the reference value BL disappears after the advertisement's broadcast, after the measurement value M of the advertisement with respect to the elapsed time after the advertisement is broadcast reaches a maximum.

[0113] (2b) In the above embodiment, the reference contribution W is determined based on one or more advertisements that were broadcast before both the first advertisement 60 and the second advertisement 70. However, it is sufficient that the reference contribution W is determined based on one or more advertisements that have a validity period ET that does not overlap with the validity periods ET of both the first advertisement 60 and the second advertisement 70. In other words, it does not matter whether the advertisements used to determine the reference contribution W are advertisements that were broadcast before the broadcast of the first advertisement 60 and the second advertisement 70, or advertisements that were broadcast after the broadcast of the first advertisement 60 and the second advertisement 70.

[0114] (2c) In the above embodiment, the first contribution degree Ta is determined based on the first reference contribution degree Wa of the first advertisement 60 corresponding to the target section, the first viewing amount Pa of the first advertisement 60, and the first area coverage rate Ca of the first advertisement 60. The second contribution degree Tb is determined based on the second reference contribution degree Wb of the second advertisement 70 corresponding to the target section, the second viewing amount Pb of the second advertisement 70, and the second area coverage rate Cb of the second advertisement 70.

[0115] However, the first contribution Ta may be determined based on the first reference contribution Wa without using at least one of the first viewing amount Pa and the first area coverage rate Ca. The second contribution Tb may be determined based on the second reference contribution Wb without using at least one of the second viewing amount Pb and the second area coverage rate Cb. In other words, in the formulas (1) and (2), the first viewing amount Pa may be set to the second viewing amount Pb, and the first area coverage rate Ca may be set to the second area coverage rate Cb.

[0116] (2d) In the above embodiment, for the first advertisement 60 and the second advertisement 70, when the effective period ET of each advertisement includes an overlap period OT, the evaluation value V of the advertising effectiveness of each advertisement during the overlap period OT is calculated by allocating the increment L corresponding to each section included in the overlap period OT based on the ratio between the first contribution degree Ta of the first advertisement 60 and the second contribution degree Tb of the second advertisement 70.

[0117] The first contribution Ta may be determined based on the first reference contribution Wa, and the second contribution Tb may be determined based on the second reference contribution Wb. The first reference contribution rate Wa and the second reference contribution rate Wb are determined based on an increment L in each of one or more sections included in the validity period ET of at least one advertisement, excluding both the first advertisement 60 and the second advertisement 70, among the multiple advertisements broadcast during the campaign period.

[0118] The first reference contribution rate Wa and the second reference contribution rate Wb are determined for each section included in the overlapping period OT. In other words, the first reference contribution rate Wa is determined based on a first elapsed time, which is the time elapsed since the broadcast of the first advertisement 60. The second reference contribution rate Wb is determined based on a second elapsed time, which is the time elapsed since the broadcast of the second advertisement 70.

[0119] Therefore, the increment L corresponding to each section included in the overlap period OT may be allocated to each of the first advertisement 60 and the second advertisement 70 in a ratio based on the first elapsed time and the second elapsed time.

[0120] (2e) In the above embodiment, a process was described for allocating the increment L when there is an overlapping period OT during which the valid periods ET of the first advertisement 60 and the second advertisement 70 overlap. However, the number of advertisements whose valid periods ET overlap is not limited to two, and may be three or more.

[0121] When there is an overlapping period OT in which the effective periods ET of N advertisements (N is an integer of 2 or more) overlap with each other, the increment L of each of one or more sections in the overlapping period OT may be calculated by allocating based on the ratio of the contribution degree Tj (j is an integer of 1 to N) of each advertisement. The evaluation value Vj of the advertising effectiveness of each advertisement in the overlapping period OT may be calculated by summing up the increment Lj allocated to each advertisement in each section.

[0122] The contribution degree Tj is the degree to which the j-th advertisement among the N advertisements contributes to the magnitude of the increment L. For example, the increment Lj obtained by allocating the increment L of each section to each advertisement based on the ratio of the contribution degree Tj of each advertisement can be determined by the following formula (5).

[0123]

number

[0124] The contribution degree Tj of each advertisement may be determined based on the reference contribution degree Wj of each advertisement. The reference contribution degree Wj of each advertisement may be corrected based on at least one of the viewing amount Pj and the area coverage rate Cj of each advertisement. For example, the contribution degree Tj of each advertisement may be calculated by multiplying the reference contribution degree Wj of each advertisement by at least one of the viewing amount Pj and the area coverage rate Cj of each advertisement.

[0125] For example, if the contribution Tj of each advertisement is calculated by multiplying the reference contribution Wj of each advertisement by both the viewing amount Pj and the area coverage rate Cj of each advertisement, the increment Lj allocated to each advertisement can be determined by the following equation (6).
