Action histories can be collected, for example, through questionnaire surveys, web browser cookie analysis, and the like. Note that the action history may be limited to actions on the Internet (history using a web browser). The action history includes the date and time of the action and the content of the action in association with the viewer ID.

Even if the viewer indicated by the viewer ID of the viewing log (that is, the viewers who make up the sample household) does not overlap with the viewer indicated by the viewer ID of the target information (for example, the viewer who answered the questionnaire) good. The similarity determination unit 111 associates the viewing log with the target information. The similarity determination unit 111 calculates the degree of similarity between the viewing behavior pattern ascertained based on the viewing log and the viewing behavior pattern ascertained based on the viewing information of the target information, and responds according to the similarity. can be applied. The degree of similarity may be determined according to, for example, the number of times the same TV program was viewed on the same date and time, or the viewed TV program or its genre, viewing time, viewing order, etc. may be compared. You may Also, for example, patterns in which TV programs or genres thereof viewed for each day of the week are arranged may be compared. The similarity determination unit 111 can associate the viewing log with the target information according to the obtained similarity.

The segment identification unit 112 identifies segments of viewers relating to television programs. The segment specifying unit 112 reads out the viewing log corresponding to the television program from the viewing log storage unit 131, and demographics of the target information (association is performed by the similarity determination unit 111) corresponding to the read viewing log. Segments are identified by attributes included in the information and actions included in the action history. It should be noted that the method of determining segments based on demographic attributes and action history is a well-known method and will not be described here. The segment identification unit 112 also calculates the number of viewers included in each segment. The segment identification unit 112 selects, for example, target information including a viewer ID belonging to the segment, identifies a viewing log corresponding to the identified target information, and eliminates duplicate viewer IDs included in the identified viewing log. , the number of viewers included in the segment can be calculated.

The evaluation unit 113 evaluates whether the television program is suitable for targeting advertisement. The evaluation unit 113 determines the suitability of the targeting advertisement according to the degree of dispersion of the viewer's segment. For example, in the case of a program that is watched by elementary school students, teenage high school girls, and male office workers in their 30s, it is unlikely that the same product will appeal to all viewers. Advertisement effectiveness is considered to be higher if different products are appealed to each male. Conversely, if a program is viewed mainly by female office workers in their thirties, it can be considered that conventional mass advertising will have a high advertising effect without switching advertisements. Therefore, the evaluation unit 113 can determine the degree of conformity according to the degree of dispersion of viewer segments. The degree of variation of segments may be represented by the number of segments, or by the distance of relationship between segments. The distance of the relationship between segments is based on, for example, various attributes that make up the segments (in this embodiment, demographic attributes and attributes obtained based on behavior history). It can be grasped as a distance in a multidimensional space. Attributes that are categorical variables can be used as axes after being converted into dummy variables. For example, the evaluation unit 113 can determine the degree of conformity such that the greater the number of segments, the higher the degree of conformity. Also, for example, in the case of a segment using gender and age, male is 1, female is 0, age is 0 for teens, 0.17 for 20s, 0.33 for 30s, and 0 for 40s. The distance can be calculated after standardizing with 0.5 for 50s, 0.67 for 50s, 0.83 for 60s, and 1 for 70 or more. For example, if there are two viewer segments, men in their teens and women in their 40s, the distance between them is the square of teens - 40s (0-0.5) + men - women (1-0 ) can be calculated as 1.12. Also, if the audience segment is women in their teens and women in their 20s, the square root of the square of teens - 20s (0-0.17) + women - women (0-0) , 0.17. The fitness can be determined such that the longer the distance, the higher the fitness. Note that the evaluation unit 113 may not consider a segment to which a small number of viewers belong. For example, the evaluation unit 113 can determine the degree of conformity according to the degree of variation in segments for a predetermined number of people or more.

The audience rating calculation unit 114 calculates the audience rating based on the viewing log. The audience rating calculation unit 114 calculates the audience rating of the program using a conventional method, and detailed description thereof is omitted here.

The program information transmitting unit 115 transmits to the user device 20 information (hereinafter referred to as "program information") including the audience rating of the television program and the adaptability of the television program to the targeting advertisement. The user device 20 displays the received program information, and the broadcasting station can determine the advertisement price based on the audience rating and which TV programs are targeted for addressable advertisement.

The evaluation device 10 performs the following processing for each television program broadcast by a broadcasting station. That is, the similarity determination unit 111 associates the viewing log with the target information (S401). As described above, the similarity determination unit 111 calculates the degree of similarity between the viewing behavior pattern ascertained based on the viewing log and the viewing behavior pattern ascertained based on the viewing information of the target information. Correspondence can be made according to degree.
The segment identification unit 112 identifies the segment to which the viewer belongs based on the target information corresponding to the viewing log corresponding to the television program (S402). Note that one viewer may belong to a plurality of segments. The segment specifying unit 112 counts the number of viewers who belong to each segment, and sets the segment having the counted number of viewers equal to or larger than a predetermined number as an advertisement segment (S403).

The evaluation unit 113 determines the suitability according to the degree of variation of the advertisement segments (S404). The evaluation unit 113 may determine that the degree of conformity increases as the variation of the advertisement segments increases. As described above, the degree of variability of ad segments can be, for example, the number of ad segments or the distance between ad segments.

The audience rating calculation unit 114 selects the viewing log corresponding to the TV program from the viewing log storage unit 131, and calculates the audience rating based on the selected viewing log (S405). For example, the audience rating calculation unit 114 can calculate the audience rating by dividing the number of unique household IDs included in the selected viewing log by the number of sample households.

After performing the above processing for each TV program, the program information transmitting unit 115 creates program information including the audience rating and the suitability for each TV program, and transmits the program information to the user device 20 (S406). The program information transmitting unit 115 may include information describing the advertisement segments corresponding to the program, the number of advertisement segments, etc. in the program information.

As described above, according to the evaluation device 10 of the present embodiment, it is possible to calculate the suitability of whether or not the targeting advertisement (addressable advertisement) is effective for the television program based on the viewing log. Therefore, it is possible to make addressable advertisements available only for programs that are suitable for targeting advertisements. can be effectively employed.

Further, according to the evaluation device 10 of the present embodiment, the segments of viewers are identified based on the viewing log, and the suitability of the targeting advertisement for the program is determined according to the number of segments of viewers who are viewing the program. can be asked for. Mass advertising aimed at all viewers in TV programs watched by a wide range of viewers is effective for branding a company's image, but it is effective for advertising for products with a limited user base. inferior in quality. According to the evaluation device 10 of the present embodiment, when there are many segments of viewers, it is possible to evaluate that the targeted advertisement is effective. By referring to the evaluation by the evaluation device 10 of the embodiment, it is possible to easily grasp which program is suitable for addressable advertisement.

Further, according to the evaluation device 10 of the present embodiment, the degree of conformity is determined according to the number of viewers belonging to the segment. Therefore, it is possible to determine the suitability considering the number of viewers targeted for the targeting advertisement while dividing into segments, and to accurately evaluate the usefulness of the targeting advertisement in the program.

In addition, according to the evaluation device 10 of the present embodiment, the targeting information includes demographic attributes and action history, and targeting advertisements according to attributes such as age, gender, income, occupation, etc. It is possible to obtain the degree of matching of targeting advertisements including action targeting according to actions such as click history and purchase history.

Further, according to the evaluation device 10 of the present embodiment, the degree of conformity can be transmitted to the user device 20 together with the audience rating. Therefore, on the user side, it is possible to perform a simulation in the case where the program corresponds to addressable advertisement while assuming an advertisement fee corresponding to the audience rating.

Further, according to the evaluation device 10 of the present embodiment, it is possible to associate the viewing log and the target information according to the degree of similarity of the viewing pattern, etc., and estimate the segment of the viewer based on the target information. Therefore, it is possible to segment the viewers of the television program, which is linear broadcasting, by using the browsing history (behavior history) of the web browser on the Internet. Therefore, it is possible to evaluate TV programs from the viewpoint of segments targeted for targeting advertisements based on a wide range of attributes and action histories as well as the viewer's basic information.

Although the present embodiment has been described above, the above-described embodiment is intended to facilitate understanding of the present invention, and is not intended to limit and interpret the present invention. The present invention can be modified and improved without departing from its spirit, and the present invention also includes equivalents thereof.

For example, in the present embodiment, the viewing log is associated with the target information, and the segment of the viewer is specified based on the target information. Audience segments may be determined.

In addition, in the present embodiment, the viewing logs are collected using the log recording device installed in the sample household, but this is not limiting. Alternatively, a viewing log (device log) recorded in the television receiver may be used. As for the device log, the television receiver may identify which viewer has watched by the viewer pressing a button, etc., or the viewing log collected by the log recorder may be machine-learned. Then, from the device log, it is possible to estimate what kind of household composition is and which member has viewed which program.

In addition, the TV receiver links mobile devices such as smartphones and tablet computers, and by recognizing the mobile devices that exist nearby when the TV receiver outputs video, individual viewers can be identified and recorded as device logs. can be made to record.

In addition, in the present embodiment, the audience rating calculation unit 114 calculates the audience rating based on the viewing log, but it is not limited to this, and an input of the audience rating calculated elsewhere may be accepted.
