(System overview)
First, an outline of the information processing system 1 according to the present embodiment will be described.
FIG. 1 is a schematic block diagram showing a configuration example of the information processing system 1 according to the present embodiment.
The information processing system 1 includes an information processing device 10 connected to a network NW. A plurality of first devices 20, a plurality of second devices 30, an external data management unit 50, and an analysis result utilization unit 60 are connected to each other in the network NW so that various data can be transmitted and received to each other.

The information processing device 10 accumulates a first log obtained by accumulating the operation information received from the first device 20 and a second log obtained by accumulating the operation information received from the second device 30. The information processing device 10 estimates the user in operation of the first device 20 based on the correlation between the operating status of each of the first devices shown in the first log and the location status of each user shown in the second log. To do. The information processing device 10 generates analysis result information including estimated user information indicating a user estimated for each operation information and the operation information.

In the present application, "shared" means that it is not exclusively for a specific individual and may be used by other people, and does not necessarily mean that it is used by a plurality of users at the same time. Further, "simultaneous" can include a period in which neither the operation information nor the detection information is maintained unchanged, and does not necessarily mean that the hours, minutes, and seconds are exactly the same.
The "group" includes two or more users who can share the first device 20. One group is a set of people who share a predetermined space. One group is not limited to households consisting of family members and relatives, and may be, for example, a group consisting of some or all members of an association, school, company, or other organization or group. The "common space" is a space in which individual users belonging to a group are constantly located as the base of their lives. A common space typically corresponds to a residence. As a dwelling, a single-family house, individual dwelling units constituting an apartment house, a student dormitory, a shared dormitory having a common space shared by a plurality of users, and the like are applicable.

In the following description, the common space is mainly a residence, the group is a household, the first device 20 is a television receiver, and the second device 30 is a mobile phone (so-called smart phone). As an example, the device 30 is dedicated to one different user. The television receiver has a function of presenting a broadcast program, but in the present application, "presentation" means one or both of reproducing audio and displaying video. "Viewing" means that the user listens to the reproduced audio and / or views the displayed video or image. In the present application, "viewing" may mean "acquisition" or "presentation" of content such as video and audio as a function of a television receiver.

Next, an outline of the functions of the information processing system 1 according to the present embodiment will be described. FIG. 2 is a diagram showing examples of operation information and detection information according to the present embodiment. In the example shown in FIG. 2, viewing information acquired from TV TV1 and TV2, respectively, and detection information acquired from mobile phones SP1, SP2, SP3, and SP4 are shown. The viewing information indicates whether or not a broadcast program is received every 15 minutes as an example of operation information. The ○ mark indicates the reception period for receiving the broadcast program, and the blank indicates the non-reception period during which the broadcast program is not received. The detection information indicates the presence or absence of each user of each mobile phone. The information processing device 10 evaluates the correlation between the operation period indicated by the operation information of the individual first device 20 and the home period indicated by the detection information of the individual second device 30. The information processing device 10 determines the presence or absence of a specific user whose correlation is higher than a predetermined correlation threshold value for each first device 20, and refers to such a user as the main user of the first device 20 (hereinafter, main). It can be determined that the user). The number of main users to be determined is not necessarily limited to one, and may be a plurality of users. In the example shown in FIG. 2, the reception period of the television TV2 is a period from 8:00 to 8:30 on January 25, 2019 and a period from 14:15 to 15:00 on the same day. On the other hand, the period of stay at home of the user C, who is the user of the mobile phone SP3, is the period from 8:00 to 8:30 on January 25, 2019 and the period from 14:00 to 15:15 on the same day. Most of this home period is occupied by the reception period of TV TV 2, and it is shown that the correlation between the home period of user C and the reception period of TV TV 2 is high. In other words, it can be said that the TV TV 2 does not operate unless the user C is at home. Therefore, the information processing device 10 can estimate that the main user of the television TV 2 is the user C. The reception period of the TV TV 1 is covered by the home period of the users AD of each of the mobile phones SP1-SP4, but there is no user who has a high correlation between the reception period of the TV TV 1 and the home period. From this, it can be estimated that if at least one of the users AD is at home, the TV TV is operating, but it is not dedicated to a specific user. As described above, according to the present embodiment, by analyzing the operation information and the detection information, the main user of the first device 20 that can be shared by a plurality of users is estimated without a dedicated investigation or installation of a device. be able to. The example of FIG. 2 is an example of clarifying the relationship between the user C and the TV TV 2 by using the relatively short-term operation information and the detection information, but each user is based on the information processing device 10 and the long-term operation information and the detection information. And the high degree of correlation of each television may be analyzed. As a result, the TV TV viewed by each user can be estimated more accurately.
In the above description, 〇 in FIG. 2 is an example of the reception period as the operation information of the television, but the present invention is not limited to this. The operation information is, as long as it is information indicating the operation status of the television, different types of operation information, for example, the startup time, the period during which various information is displayed on the screen, the time zone during which the user's operation is accepted, and the like. You may.

When the detection information and the operation information can be acquired in association with each other, for example, when the detection information and the operation information can be acquired via a common access point in the group, or when the detection information and the operation information from a plurality of devices in the group can be acquired at once. ,and so on. In the user identification information column, user identification information for identifying a user dedicated to each linked device is described. However, the user identification information for the first device 20 shared by a plurality of users, such as "TV1" and "TV2" in FIG. 5, may not be set.
In addition, instead of the user identification information or together with the user identification information, individual identification information such as an advertisement identification information (advertisement identification information) and an e-mail address of each user may be described.

FIG. 5 is a diagram showing an example of a viewing log according to the present embodiment.
The viewing log WT06 is an example of the first log. The viewing log WT06 is configured to include viewing information including a set of device identification information (device ID), viewing start time information, viewing end time information, and viewing channel information (viewing CH) as operation information. In the example shown in FIG. 5, each operation information is configured for each viewing period. The viewing period is defined by viewing start time information and viewing end time information indicating the start time and end time, respectively.
In the example shown in the second line of FIG. 5, the first device 20 whose device identification information is "TV1" broadcasts the broadcast program of the viewing channel "1" from 16:32:23 to 2018 on November 28, 2018. It indicates that it was received until 17:01:04 on November 28, 2014.

When configuring the operation information for each viewing period, the control unit 230 of the first device 20 specifies each one viewing period based on the plurality of operation commands or the operation status corresponding to the operation commands. The control unit 230 determines, for example, the start of power supply (power ON), the start of content presentation, or the change of the broadcast channel from another broadcast channel as the start of viewing, which is indicated by the operation command acquired at a certain time. .. The control unit 230 determines that the power supply stop (power OFF), the content presentation end, or the change of the broadcast channel to another channel specified by the operation command acquired immediately after that is the end of viewing. The control unit 230 has viewing start time information indicating the time when the viewing start is determined, viewing end time information indicating the time when the viewing end is determined, and viewing indicating the channel set at that time or the broadcast channel instructed to change. Generate channel information. From a different point of view, the control unit 230 can be regarded as reconstructing the operation information for each viewing period by using at least two or more operation information indicating the operation status as individual events.

The control unit 230 may transmit the operation information for each viewing period to the information processing device 10 as it is without necessarily reconstructing the operation information for each viewing period from the operation information indicating the individual operation status. Further, the information storage unit 130 of the information processing device 10 may transmit an operation information request signal to the first device 20 via the communication unit 120 at predetermined time intervals. When the control unit 230 of the first device 20 receives the operation information request signal from the information processing device 10, it transmits the operation information indicating the operation status at that time as a response to the operation information request signal (polling). When the operation information is transmitted as it is without reconstructing the operation information for each viewing period, the viewing log accumulates the operation information indicating the individual operation status as it is in the information storage unit 130 of the information processing device 10. Is formed. The information analysis unit 142 or the analysis result utilization unit 60 of the information processing device 10 can determine one viewing period from each of a plurality of operation information by the same method as the control unit 230.

FIG. 6 is a diagram showing an example of program information according to the present embodiment.
The program information PG08 is an example of external data. The program information PG08 includes broadcast time information (broadcast start time, broadcast end time), broadcast channel information (CH), and related information for each broadcast program, and is configured by associating these with each other. The related information includes information indicating the attributes of the broadcast program, for example, information such as a title (program name), a genre, and a performer. In the example shown in FIG. 6, information on the genre to which each broadcast program belongs is included as related information.
In the second line of FIG. 6, the broadcast time starts at 16:30:00 on November 28, 2018, ends at 17:30:00 on November 28, 2018, and the broadcast channel is "1". An example is a program whose genre is "cooking".

FIG. 7 is a diagram showing an example of a home log according to the present embodiment.
The home log IH10 is an example of a second log containing detection information. The home log IH10 includes home time information (home start time, home end time) and device identification information (device ID) for each home period, and is configured by associating these. The period of stay at home is a period in which users are continuously located in a predetermined residence, which is a space common to a plurality of users.
In the example shown in FIG. 7, each detection information is configured for each period of stay at home. As the home start time, for example, the time when the control unit 330 of the second device 30 determines that it has entered the range of coverage that enables communication via the access point installed in a certain residence is stored. The control unit 330 is a notification received from the access point when the radio wave intensity received from the access point by the communication unit 310 using a predetermined communication method is below the threshold value of the predetermined radio wave intensity and exceeds the threshold value. When the device identification information of the access point included in the signal is the predetermined device identification information, it can be determined that the device has entered the coverage range. When the communication method specified in IEEE802.11 is used, for example, SSID (Service Set ID) can be used as the device identification information of the access point.

As the home end time, for example, the time when the control unit 330 of the second device 30 determines that the device has left the coverage area is stored. The control unit 330 is a state in which the radio wave strength received from the communication unit 310 from the access point exceeds the threshold value of the predetermined radio wave strength and falls below the threshold value, or when the radio wave strength is included in the notification signal received from the access point. When the device identification information is not the predetermined device identification information, it can be determined that the device has left the area of coverage.
In the fourth line of the home log IH10, the home end time column is blank because the mobile phone SP1 indicated by the device ID is within the coverage of the predetermined access point at that time, that is, , Indicates that the user of the mobile phone SP1 is at home.

The control unit 330 does not necessarily reconstruct the detection information for each period of stay from the detection information indicating the individual location status, but the information processing device 10 as it is, the detection information indicating entry or exit from the coverage of a predetermined access point. May be sent to. In addition, the control unit 330 of the second device 30 generates detection information indicating whether or not the own device is located within the coverage range at predetermined time intervals (for example, 5 to 30 minutes) and processes information. It may be transmitted to the device 10.
The information storage unit 130 of the information processing device 10 may transmit a detection information request signal to the second device 30 via the communication unit 120 at predetermined time intervals. When the control unit 330 of the second device 30 receives the detection information request signal from the information processing device 10, the control unit 330 receives the detection information indicating whether or not it is located within the coverage at that time as a response to the detection information request signal. Send (polling).

Next, a specific example of processing by the information analysis unit 142 of the information processing device 10 will be described.
The information analysis unit 142 reads out the operation information from each of the first devices 20 belonging to the group and the detection information from each of the second devices 30 for each group, and reads the operation status of each of the first devices 20 at predetermined time intervals. The integrated table TB12 is configured by integrating the operation information indicating the above and the detection information regarding the location status of each user from the second device 30 in a predetermined space.
FIG. 8 is a diagram showing an example of an integrated table according to the present embodiment. In the example shown in FIG. 8, the integrated table TB12 includes operation information indicating the presence / absence of operation of each of the television TV1 and TV2 and detection information indicating the presence or absence of each of the mobile phones SP1, SP2, SP3, and SP4 for each time information. , These are associated and configured. The time information includes the year, month, day, day of the week, hour, and minute elements at that time. The numerical values 1 and 0 described in the columns of TV TV1 and TV2 are examples of operation information indicating that they are operating and stopped, respectively. The numerical values 1 and 0 described in the columns of the mobile phones SP1, SP2, SP3, and SP4 are examples of detection information indicating the presence or absence of each user at home.
The integrated table TB12 shown in FIG. 8 is formed by integrating the operation information and the detection information every 30 minutes, but the present invention is not limited to this. The time interval between the operation information and the detection information may be different depending on the purpose of the analysis. The time interval can be, for example, 1 minute, 3 hours, and so on. Further, depending on the analysis period, all the elements of the time information, for example, the year, may not be included. Conversely, the time information may include more detailed elements such as seconds and milliseconds.

The information analysis unit 142 analyzes the correlation between the detection information related to each of the mobile phones SP1-SP4 and the operation information related to each of the televisions TV1 and TV2. The information analysis unit 142 includes, for example, the location status of the mobile phone SP and the television for each group consisting of one mobile phone SP among the mobile phones SP1-SP4 and one TV TV among the TV TV1 and TV2. The cumulative time for each pattern consisting of the operating status of the TV is totaled. Then, the information analysis unit 142 calculates the ratio of the cumulative time during which the operation status is operating to the cumulative time under the predetermined location status as the utilization rate, and the cumulative time during which the operation status is stopped among the cumulative time. Is calculated as the non-utilization rate. The non-utilization rate, which is the ratio of the stop time (that is, non-operation time) that the operation status is stopped (that is, non-operating) to the absence time that makes this location status absent, or the location status is defined as being at home. The utilization rate, which is the ratio of the operating time to the operating time, which is the ratio of the operating time to the operating time, is the correlation between the operating status of each of the TV TV1 and TV2 and the location status of each user of the mobile phones SP1-SP4, that is, Shows the degree of involvement of each user in the use of each television.

FIG. 9 is a diagram showing an example of the cumulative time for each operating status of the TV TV for each pattern of the location status of the mobile phone SP according to the present embodiment. 9 (a)-(h) are absent (0) and at home (1) as the location status of one mobile phone SP in each row, and stopped (0) as the operation status of one TV TV in each column. , At home (1). The cumulative time is shown in the upper row, and the utilization rate or non-utilization rate is shown in the lower row for each pattern of location status and operation status. FIG. 9A shows the cumulative time when the location status of the mobile phone SP1 is absent (0), the operating status of the TV TV 2 is stopped (0), and the operating status is operating (1). 381 hours and 23 hours, respectively. Since the total cumulative time when the location status of the mobile phone SP1 is absent (0) is 404 hours, the non-utilization rate and the utilization rate are 0.9431 and 0.0569, respectively.

The information analysis unit 142 calculates the non-utilization rate when the location status is absent for each set of one mobile phone SP and one TV TV, and the average value and standard deviation of the calculated non-utilization rate between the mobile phones. Is calculated for each TV. Then, the information analysis unit 142 calculates the normalized value obtained by dividing the deviation between the non-utilization rate and the average value calculated for each set of one mobile phone SP and one TV TV by the standard deviation. .. This normalized value corresponds to the deviation value. The information analysis unit 142 assumes the cumulative probability based on the normal distribution, and calculates the cumulative probability corresponding to the normalized value as the degree of involvement of the user of the mobile phone SP in the TV TV. However, when the normalized value is 0 (that is, when the non-utilization rate is equal to the average value), the cumulative probability is set to 50%, and the larger the normalized value, the closer the cumulative probability is to 100%.

FIG. 10 is a diagram showing an analysis example of the correlation between the detection information related to each mobile phone SP and the operation information related to each TV TV. FIG. 10 shows an example of the non-utilization rate, the normalized value, and the degree of involvement in the absence of each pair of the mobile phone SP and the TV TV.
Regarding the TV TV 2, the non-utilization rate of the mobile phone SP3 in the absence is the highest at 0.9838, and the degree of involvement corresponding to this non-utilization rate is 92.3%. This indicates that the main user of the television TV2 is most likely to be the user of the mobile phone SP3. On the other hand, the non-utilization rate of the mobile phone SP4 when absent is 0.9244, which is the lowest, and the degree of involvement corresponding to this non-utilization rate is 23.7%. This indicates that the main user of the television TV 2 is the least likely to be the user of the mobile phone SP4.
Regarding the TV TV 1, the non-utilization rate of the mobile phone SP1 in the absence is the highest at 0.9282, and the degree of involvement corresponding to this non-utilization rate is 93.3%. This indicates that the main user of the television TV1 is most likely to be the user of the mobile phone SP1. On the other hand, the non-utilization rate of the mobile phone SP4 when absent is the lowest at 0.6196, and the degree of involvement corresponding to this non-utilization rate is 28.7%. This indicates that the main user of the television TV 1 is the least likely to be the user of the mobile phone SP4.
Note that FIG. 10 is an example of calculating the degree of involvement based on the non-utilization rate of each mobile phone SP when it is absent, but the present invention is not limited to this. The information analysis unit 142 may calculate the degree of involvement based on the utilization rate at home.

(Estimation of viewers)
The information analysis unit 142 estimates the TV TV to be watched by the user of the mobile phone SP based on the degree of involvement calculated for each TV TV for each user of the mobile phone SP.
However, in the example shown in FIGS. 11 to 13, the number of TV TVs is set to 2 for the sake of simplicity, but it can also be applied when the number of TVs is 3 or more. Before performing the processing shown in each example, the mobile phone SP [X] (X is a code for identifying each mobile phone) is the television [Y] (Y is an individual television) in descending order of involvement. The order of the identification codes) is defined.

FIG. 11 is a diagram showing a first example of a method of estimating a television TV to be viewed by a user of a mobile phone SP.
When the location status of the mobile phone SP [X] is absent, the information analysis unit 142 determines that the user of the mobile phone SP [X] is not watching any TV TV [Y] (“NONE”). To do.
In other cases, the information analysis unit 142 allows the user of the mobile phone SP [X] to use the TV TV even when any of the operating states of the TV TV [Y] is stopped (power state = OFF). It is determined that [Y] is not viewed (“NONE”).
In other cases, the information analysis unit 142 is in the operating state of the television TV [1] having the highest degree of involvement (power state = ON), and the pseudo random number RAND (0,1). Is lower than the degree of involvement of the mobile phone SP [X] in the television TV [1], it is estimated that the user of the mobile phone SP [X] is watching the television TV [1] (“TV [1]”). Here, the pseudo-random number RAND (0, 1) indicates a uniform pseudo-random number whose minimum value and maximum value are 0 and 1, respectively.
In other cases, the information analysis unit 142 is in operation (power state = ON) of the television TV [2] having the next highest degree of involvement, and the pseudo random number RAND (0, When 1) is lower than the ratio of the degree of involvement of the mobile phone SP [X] and the TV TV [2] to the degree of involvement of the mobile phone SP [X] and the TV TV [1], the mobile phone SP [X] The user presumes that he is watching TV TV [2] (“TV [2]”).
According to this method, when each operating state of the television TV [Y] is operating, the information analysis unit 142 has a probability corresponding to the degree of involvement corresponding to each of the operating states of the mobile phone SP [X]. The television that the user watches is estimated to be television TV [Y].

When the number of TV TVs is 3 or more and the user of the mobile phone SP [X] does not estimate that the TV TV [Y-1] (Y is an integer of 2 or more) is viewed. , The information analysis unit 142 estimates that the user of the mobile phone SP [X] is watching TV TV [Y] under the following conditions. The condition is that the operating status of the TV TV [Y] is operating, and the pseudo-random number RAND (0,1) is related to the degree of involvement of the mobile phone SP [X] in the TV TV [Y-1]. The condition is that it is lower than the ratio of the degree of involvement with.

FIG. 12 is a diagram showing a second example of a method of estimating a television TV to be viewed by a user of a mobile phone SP.
When the location status of the mobile phone SP [X] is absent, the information analysis unit 142 determines that the user of the mobile phone SP [X] is not watching any TV TV [Y] (“NONE”). To do.
In other cases, the information analysis unit 142 allows the user of the mobile phone SP [X] to use the TV TV even when any of the operating states of the TV TV [Y] is stopped (power state = OFF). It is determined that [Y] is not viewed (“NONE”).
In other cases, when the operating status of the television TV [1] having the highest degree of involvement is operating (power state = ON), the information analysis unit 142 can be used by the user of the mobile phone SP [X]. , TV TV [1] is presumed to be viewed (“TV [1]”).
In other cases, the information analysis unit 142 of the mobile phone SP [X], when the operating status of the TV TV [2] having the next highest degree of involvement is operating (power state = ON). The user presumes that he / she is watching TV TV [2] (“TV [2]”).
According to this method, the information analysis unit 142 is a television receiver in which the user of the mobile phone SP [X] watches the television receiver having the highest degree of involvement among the operating television TVs [Y]. Will be estimated as.

When the number of TV TVs is 3 or more and the user of the mobile phone SP [X] does not estimate that the TV TV [Y-1] (Y is an integer of 2 or more) is viewed. The information analysis unit 142 may presume that the user of the mobile phone SP [X] is watching the TV TV [Y] when the operating status of the TV TV [Y] is operating.

FIG. 13 is a diagram showing a third example of a method of estimating a television TV to be viewed by a user of a mobile phone SP. In this example, the step of estimating that the television TV [1] having the highest degree of involvement in the second example is the television receiver being watched, and the television TV [2] having the next highest degree of involvement in the first example. ] Corresponds to a process that combines the steps of estimating the television receiver on which the subsequent television is being watched.
That is, in the information analysis unit 142, when the location status of the mobile phone SP [X] is absent, the user of the mobile phone SP [X] is not watching any TV TV [Y] (“NONE”). Is determined.
In other cases, the information analysis unit 142 allows the user of the mobile phone SP [X] to use the TV TV even when any of the operating states of the TV TV [Y] is stopped (power state = OFF). It is determined that [Y] is not viewed (“NONE”).
In other cases, when the operating status of the television TV [1] having the highest degree of involvement is operating (power state = ON), the information analysis unit 142 can be used by the user of the mobile phone SP [X]. , TV TV [1] is presumed to be viewed (“TV [1]”).
In other cases, the information analysis unit 142 is in operation (power state = ON) of the television TV [2] having the next highest degree of involvement, and the pseudo random number RAND (0, When 1) is lower than the ratio of the degree of involvement of the mobile phone SP [X] to the TV TV [1] to the degree of involvement of the mobile phone SP [X] to the TV TV [2], the user of the mobile phone SP [X] uses the TV TV [2]. Estimated to be viewing (“TV [2]”).

In the second example shown in FIG. 12, the information analysis unit 142 is involved in the non-utilization rate or the location, which is the ratio of the downtime to the absent time for each pair of one TV and one mobile phone. The utilization rate, which is the ratio of the operating time to the time, may be used.
Further, in any of the examples of FIGS. 11 to 13, only one TV TV [Y] is in operation, and the other TV TVs [Y'| Y'≠ Y] are in operation. It may be stopped. In that case, the information analysis unit 142 determines that the user of the mobile phone SP [X] whose location is at home is watching TV TV [Y], and the mobile phone SP [X'| X'" whose location is absent. It may be determined that the user with ≠ X] is not watching TV TV [Y].

The information analysis unit 142 identifies a user who is presumed to be using the first device for each operation information that constitutes the first log and indicates that the operation is in operation. The information analysis unit 142 accumulates the combined information obtained by adding the device identification information of the second device related to the specified user to the operation information as a form of the estimated user information and generates it as the analysis result information.
The information analysis unit 142 uses a period in which the operation period indicated by the operation information for each device identification information of the second device 30 of each user overlaps with the location period in which the location status of the user is located. You may decide. The information analysis unit 142 replaces each operation period with a usage period, adds each device identification information as estimated user information and generates it as combined information, and generates the combined information for each usage period as cumulative analysis result information. May be good.
The generated analysis result information includes the above-mentioned analysis result information and information as a whole, but the combination information is configured for each device identification information of the second device 30 of each user, and each combination information is an individual user. It differs in that it indicates the use of.
When the second device 30 is a television receiver, the information analysis unit 142 extracts and extracts the program-related information corresponding to the viewing channel information included in the individual operation information from the program information. Further relevant information may be added to the join information.

FIG. 14 is a diagram showing an example of analysis result information according to the present embodiment. The analysis result information AR18 is information generated based on the operation information of the televisions TV1 and TV2 as the first device 20 and the detection information of the mobile phones SP1-SP4 as the second device 30. The analysis result information AR18 includes estimated user information (SP), device identification information (device ID), viewing period (viewing start time, viewing end time), viewing channel information (viewing CH), and related information, and corresponds to these. It is configured to include the attached binding information. Of the analysis result information AR18, the 2nd to 5th lines of the analysis result information AR18 show the combined information for each viewing period as the usage period of the user of the mobile phone SP1. All of these combined information are related to the television TV 1, and indicate that the user of the mobile phone SP1 was watching the broadcast program using the television TV 1 during each viewing period. The 6th to 9th lines of the analysis result information AR18 show the combined information for each viewing period of the user of the mobile phone SP2. However, the sixth, seventh, eighth, and ninth lines relate to TVTV1, TV1, TV2, and TV2, respectively. This means that the user of the mobile phone SP3 initially used TV TV1 when watching the broadcast program, but changed the TV used at 20:28:49 on November 28, 2018 to TV TV2. Shown.

Among the users belonging to a certain group, the information analysis unit 142 belongs to the group for the user whose period in the space common to the group is shorter than the lower limit of the predetermined analysis target period or the second device 30. It may be determined that the user does not exist and excluded from the analysis target. The lower limit of the analysis target period may be a value comparable to the location period and frequency, such as a period sufficiently shorter than the analysis period (for example, 1 to 6 months), the number of days, and the number of times. This is because such a user may not be constantly or regularly located in a predetermined common space such as a visitor.

When the information analysis unit 142 analyzes the correlation between the operation information and the detection information and estimates the user of the first device 20, a specific period in a predetermined cycle (for example, a specific day of the week, a day of the week) A specific time zone (morning, noon, evening, night, etc.) may be set as the analysis period to be analyzed. This makes it possible to analyze the characteristics of the main users in a specific period and the differences between the users in each period.

The information analysis unit 142 may estimate the user for each content acquisition route of the first device 20 instead of estimating the user for each first device 20. Here, the information analysis unit 142 uses the operation information indicating the operation status of each content acquisition path at the time of each operation of the first device 20 in the estimation of the user.
For example, the first device 20 may be a television receiver having an external input terminal and capable of presenting a video (hereinafter, external input video) indicated by a video signal input from the external input terminal in addition to the broadcast wave. is there. In that case, the control unit 230 of the first device 20 may include external input video information indicating non-presentation of the external input video as the operation information instead of the viewing channel information. Then, when the information analysis unit 142 of the information processing device 10 generates the integrated table, as the operation status of each first device 20, the presence / absence of the broadcast reception information indicating whether or not the broadcast program is received and the presence / absence of the input of the external input video are set. It may include the external input information to be shown. When the operation information indicating that the operation is in progress includes the operation channel information, the information analysis unit 142 includes broadcast reception information indicating reception of the broadcast program of the first device 20 and external input information indicating no external input video is presented. To generate. When the operation information indicating that the operation is in progress includes the viewing channel information, the information analysis unit 142 includes broadcast reception information indicating reception of the broadcast program of the first device 20 and external input information indicating non-presentation of the external input video. To generate. When the operation information indicating that the operation is in progress includes the external input video information, the information analysis unit 142 has the broadcast reception information indicating that the broadcast program of the first device 20 has not been received and the external input indicating the presentation of the external input video. Generate information.

The information analysis unit 142 may configure the integrated table TB20 by including broadcast reception information and external input information as operation information of each of the first devices 20. The integrated table TB20 illustrated in FIG. 15 includes broadcast reception information and external input information as operation information indicating the operation status of each of the televisions TV1 and TV2. The broadcast reception information of each of TV TV1 and TV2 is shown in the column with the title "(broadcast)". “1” and “0” are values indicating reception and non-reception of the broadcast program, respectively. The external input video information of each of the TV TV 1 and the TV 2 is shown in the column with the title "(external)". “1” and “0” are values indicating presentation and non-presentation of the external input video, respectively. This makes it easy to estimate the user by independently analyzing the correlation between the viewing status of the broadcast program and the viewing status of the externally input video with the detection information. Therefore, a user mainly involved in viewing a broadcast program and a user mainly involved in viewing an external input video can be estimated independently. As a user involved in viewing externally input video, for example, the attribute of a user who mainly watches video displayed on the display unit of a television receiver for a video signal input from a game device (so-called game machine) or a recording device. The analysis becomes possible in the analysis result utilization unit 60.
In addition, the information analysis unit 142 replaces the reception of the broadcast program with the externally input video as a content acquisition route, or detects the viewing status of the broadcast program for a predetermined broadcast channel in parallel with the separation. You may analyze the correlation with the information and estimate the user for the broadcast channel. As a result, the analysis result utilization unit 60 can analyze the attributes of the user for the broadcasting service by the specific broadcasting channel.

(Modification example)
In the above description, when the information analysis unit 142 analyzes the non-utilization rate or the utilization rate as a correlation between the detection information related to each of the plurality of mobile phones and the operation information related to each of the plurality of television receivers. However, it is not limited to this. The information analysis unit 142 uses a set of operation information of each of the first devices 20 and detection information of the second device 30 as input information for each group, performs arithmetic processing using a predetermined machine learning algorithm, and determines as output information. User information indicating whether or not the first device 20 is used for each user of the second device 30 may be estimated for each first device 20 located in the space. However, the information analysis unit 142 uses a set of operation information of each of the first devices 20 and detection information of the second device 30, which are known input information for each group, and user information which is known output information. , The model parameters used for arithmetic processing may be learned.
Further, when the information analysis unit 142 estimates the output information from the input information by arithmetic processing, the configuration of the user and the device, that is, the number of the first device and the number of the second device are common to the own group. The model parameters learned for may be used.
As a predetermined machine learning algorithm, for example, a neural network, AdaBoost, XGBost, and the like can be used.

The second device 30 is not limited to the mobile phone, and may be an information terminal device of other forms such as a tablet terminal device, a personal computer, and a wearable terminal. The wearable terminal may be in any form such as a glasses-type terminal device, a wristwatch-type terminal device, or a key chain-type terminal device. For the user who uses the plurality of second devices 30, the information analysis unit 142 indicates that the location status detected by at least one of the plurality of second devices 30 is out of the office. The location status of the user is estimated to be out of the office, and when the location status detected by all the second devices 30 is at home, the location status of the user is estimated to be at home.

The second device 30 is not limited to a portable information terminal device that is convenient for the user to carry, and may be a stationary information terminal device. Further, the number of the second devices 30 may be one as long as individual users belonging to the group can be identified. The control unit 330 of the second device 30 can specify the login time as the use start time and the subsequent logout time as the use end time for the user who succeeded in the authentication at the time of login. The control unit 330 must change the operation mode from the standard mode to the sleep mode, stop the display of various images, and further perform the login process even if the operation is not continuously performed for a predetermined time or longer after login. , It may not be possible to resume use. The sleep mode is a form of an operation mode in which power consumption is lower than that of the standard mode, and is a mode in which the output of various information to the display is stopped and the execution of the program executed at that time is stopped. Therefore, the control unit 330 can specify the time when the operation mode is changed from the standard mode to the sleep mode as the end time of use. The control unit 330 associates the device identification information of the own device, the operation information including the use start time and the use end time with the operation period, and the user identification information indicating the user who has succeeded in the authentication, and attaches the user identification information to the information processing device 10. You may send it. The information analysis unit 142 of the information processing apparatus 10 may receive the operation information and the user identification information in association with each other from the second device 30, and may adopt the received user identification information as the user estimation information.

The communication unit 210 of at least one first device 20 belonging to the group may have a function as a radio base station device (so-called access point function). In that case, the communication unit 210 transmits a notification signal at predetermined time intervals according to a predetermined wireless communication method, and receives a response signal as a response to the notification signal. The communication unit 210 detects a device that is the source of the received response signal, and connects the detected device to other devices so as to be able to communicate with each other. In that case, the base station device separate from the first device 20 and the second device 30 may be omitted.
The control unit 330 of the second device 30 that functions as another device receives the notification signal transmitted from the first device 20 at a predetermined radio wave strength or higher, and the base station identification information included in the notification signal is predetermined. When it is the base station identification information, it may be determined that the own device or the user of the own device is located in the common space. When the radio wave strength of the received notification signal is less than the predetermined radio wave strength, or the base station identification information included in the notification signal is not the predetermined base station identification information, the control unit 330 is used by the own device or the user of the own device. Judge that they are not located in a common space. The control unit 330 transmits the detection information indicating the presence / absence in the common space to the information processing device 10 by using the communication unit 310.

Further, the control unit 330 of the second device 30 receives the notification signal transmitted from the first device 20 at a predetermined radio wave strength or higher, and the base station identification information included in the notification signal is the predetermined base station identification information. At this time, the response signal may be transmitted to the first device 20 including the device identification information of the own device as a response to the notification signal. When the control unit 230 of the first device 20 receives the response signal from the second device 30 within a predetermined reception period after transmitting the notification signal, the control unit 230 indicates the existence of the own device or the user of the own device in the common space. The detection information may be transmitted to the information processing apparatus 10 as the detection information related to the first device 20. When the control unit 230 of the first device 20 does not receive the response signal from the second device 30 within a predetermined reception period after transmitting the notification signal, the control unit 230 indicates the absence of the own device or the user of the own device in the common space. The detection information may be transmitted to the information processing apparatus 10 as the detection information related to the first device 20.

When transmitting the detection information to the information processing device 10, the control unit 330 of the second device 30 may go through any of the first devices 20 belonging to the group of the own device. In that case, the control unit of the first device 20 aggregates the detection information received from the above-mentioned second device 30 and the operation information transmitted from the other second device 30 belonging to the group, and combines it with the operation information of the own device. It may be associated and transmitted to the information processing apparatus 10. In that case, the information storage unit 130 of the information processing apparatus 10 does not necessarily have to refer to the global address of the transmission source to specify each group.
Further, the control unit 330 of the second device 30 synchronizes data with the control unit 230 of the first device 20, and the detection information indicating the location status in the common space at that time is connected to the own device. During the period, the data may be transmitted to the first device 20 at predetermined time intervals (for example, 1 to 15 minutes). The control unit 230 of the first device 20 associates the operation information generated by its own unit with the connection information indicating whether or not there is a connection with the second device 30 as a form of detection information and transmits the information processing device 10. When the information storage unit 130 of the information processing device 10 includes the operation information of the first device 20 common to the plurality of second devices 30, the first device 20 and the plurality of second devices 30 are in the same group. It can be determined that it belongs. Further, when the information storage unit 130 receives the detection information with the other first device 20 as the transmission source among the plurality of second devices 30, the transmission source belongs to the group to which the second device 30 belongs. It can be determined that the other first device 20 also belongs to. In the data synchronization, as the information to be shared, for example, a cookie acquired when the browser is executed in each of the first device 20 and the second device 30 can be used. In such a case, the second device 30 does not necessarily have to have a function as a base station device, and when transmitting to the information processing device 10, the second device 30 goes through a base station device installed in a common space. No need to do.

The information storage unit 130 of the information processing device 10 may refer to the device registration information set in advance in its own unit when specifying the group to which the device of the source of the operation information or the detection information belongs. The information storage unit 130 uses the communication unit 120 to receive device registration information from either the first device 20 or the second device 30. The device registration information is configured to include device identification information for each device belonging to one group. When the second device 30 is a mobile phone, the information storage unit 130 may generate user identification information for identifying the user of each second device 30. The information storage unit 130 stores user registration information including a set of generated user identification information and terminal registration information for each group. The user registration information for each group may include group identification information for that group.
When the analysis result utilization unit 60 has an advertisement distribution function, the information storage unit 130 generates advertisement identification information indicating the second device 30 to which the advertisement is distributed for each device identification information, and the generated advertisement. The user registration information may be generated by further including the identification information and associating with the device identification information indicating the second device 30.

Further, the information storage unit 130 uses the communication unit 120 to indicate the location of a space in which a plurality of first devices 20 are installed in addition to the device registration information from either the first device 20 or the second device 30. You may receive location information. In that case, at least each device identification information of the first device 20 is included in the device registration information, and position information indicating the position of the own device can be acquired from the second device 30 as a form of detection information. If possible, the device registration information may not include the device identification information of the second device 30. The location information includes, for example, the address of the space where the first device 20 is installed. When the second device 30 has a GPS (Global Positioning System) function, it can detect the position of its own device based on the reception time difference between GPS signals transmitted from a plurality of predetermined GPS satellites. The information storage unit 130 refers to map information indicating an address set in its own unit and a set of latitude and longitude of the position (hereinafter, latitude / longitude), and determines the latitude / longitude corresponding to the address included in the location information. Identify and add the identified latitude and longitude to the location information. The information storage unit 130 compares the first latitude / longitude indicated by the position information acquired from the second device 30 with the second latitude / longitude indicated by the location information. In the information storage unit 130, the second latitude included in the second latitude / longitude is within a predetermined latitude range (for example, 0.2 to 0.4 seconds) from the second latitude included in the first latitude / longitude, and the first When the second longitude included in the two latitudes and longitudes is within the range of the predetermined longitude from the first latitude included in the first latitude and longitude (for example, 0.2 to 0.4 seconds), the information storage unit 130 is the first. 2 As the location status of the user of the device 30, it can be determined that the user is located in the space of the group.

The second device 30 is not limited to the information terminal device, and may be any device as long as the user belonging to the group can acquire the detection information related to the location information in a predetermined common space. Further, the second device 30 is not necessarily dedicated to one specific user, but may be a device shared by two or more users. More specifically, the second device 30 may be a voice input device. The voice input device realizes an interactive input operation by using the voice recognition result for the voice data indicating the voice spoken by the user. The voice input device executes the process instructed by the utterance content for the picked-up voice signal, and generates event information indicating the operation and the utterance content. The voice input device is also called a so-called smart speaker, an AI (Artificial Intelligence) speaker, a voice assistant, or the like. The voice recognition unit (not shown) that performs voice recognition processing calculates an acoustic feature amount indicating utterance characteristics from input voice data, and identifies a user involved in utterance based on the calculated voice feature amount. The voice recognition unit may be built in the voice input device, or may be configured as a server device separate from the voice input device. The voice input device can determine the location or absence of the user based on the utterance content obtained as the voice recognition result. For example, when the content of the utterance "I'm home" is recognized, the voice input device can determine that the user related to the utterance is returning home (starting at home). When the content of the utterance "I'm going" is recognized, the voice input device can determine that the user involved in the utterance is out (end at home).

The second device 30 may be a sensor device that detects the entry or exit of a person into the house. The sensor device may be implemented as a so-called entrance sensor or the like. The entrance sensor is installed at the entrance and detects the exit or entry of a person from the entrance as an event, and estimates the user who indicates the exit or entry. Existing sensor technology can be used as the exit or entry detection principle, and dependent pattern recognition technology such as image recognition can be used when recognizing the user related to exit or entry. When the entrance sensor detects the entry of the recognized user, it can determine that the user has returned home (started at home). When detecting the exit of the recognized user, the voice input device can determine that the user is out (end at home).
Such a sensor device may function not as the second device 30 but as a beacon device that transmits the detection information indicating the entry or exit of the user recognized by the second device 30 to the second device 30. The sensor device may be set in advance by associating the user's identification information with the identification information of the second device, and the second device 30 corresponding to the recognized user may be specified as the transmission destination of the detection information. , A predetermined second device 30 in the group may be specified as a transmission destination of the detection information. When the control unit 230 of the second device 30 receives the detection information from the sensor device, the control unit 230 transmits the received detection information to the information processing device 10.

The sensor device does not necessarily have to be a device independent of other devices. For example, the first device 20 may be equipped with a motion sensor that detects the presence or absence of a person around the device 20. In that case, the control unit 230 of the first device 20 may add the information detected by the motion sensor as the detection information to the operation information indicating the operation status of the own device and transmit it to the information processing device 10. The timing of transmission may be a predetermined time interval, or may be a time when the detection information provided by the motion sensor has changed. When the information analysis unit 142 of the information processing device 10 analyzes the operation information of the first device 20, when the detection information added to the operation information indicates the existence of a person, the information analysis unit 142 adopts the operation information and the detection information. When indicates the absence of a person, it may be rejected without adopting the operation information.

The information analysis unit 142 of the information processing apparatus 10 is the same as the operation information when analyzing the correlation between the operation information included in the first log belonging to the group and the detection information included in the second log as described above. Use the period detection information. However, the operation information of the first device 20 and the detection information of the second device 30 are not always available. For example, the information processing device 10 may not be able to acquire one or both of the operation information and the detection information because the first device 20 or the second device 30 cannot be connected to the network or cannot operate because power is not supplied. It is possible. In addition, there may be cases where the acquired data is suspicious due to the loss of operation information or detection information data due to problems with the server or the Internet route, or the generation of abnormal data. The information analysis unit 142 may set the period during which such data loss is detected as the information unavailability period. When the acquisition of operation information and detection information is set in the information analysis unit 142 from the first device 20 and the second device 30 at regular intervals, the information analysis unit 142 performs the time when each information is last acquired. When new available information is not acquired for a certain period (for example, two cycles) or more starting from, it can be determined that the information unavailability period starting from that time has started. Further, the information analysis unit 142 may determine that the information unavailability period has expired with the time point at which the new available information can be acquired again as the end point, or the information analysis unit 142 cannot acquire the new available information. If it is in a state, it may be determined that the information unavailable period has continued until now. Further, even if the operation information and the detection information can be acquired, the information analysis unit 142 cannot use the information for the period related to the information when it is determined that at least one of the acquired operation information and the detection information is not suitable for use. It may be determined as a period. For example, the information analysis unit 142 determines that the amount of information is smaller than the amount of information of the operation information or the detection information acquired in the same period (for example, the time zone) of the previous week, for example. Period, operation information that cannot occur in the first log (for example, reception of a broadcast channel different from the area where the first device 20 is installed), detection information period that cannot occur in the second log (used as detection information) The movement speed of the second device 30 indicated by the position information is higher than the threshold value of the predetermined speed (for example, 600 km / hour), and the operation information or detection that overlaps with other operation information or detection information related to the same period, respectively. The information may be determined as unsuitable information, that is, unusable information. The information analysis unit 142 does not have to analyze the correlation between the operation information and the detection information during the period when at least one of the operation information and the detection information is unavailable. Further, the information analysis unit 142 indicates that the information unavailable period is a period of the same phase (for example, the same day of the week within a week) within a predetermined cycle related to the user's life pattern and does not correspond to the information unavailable period. The correlation between the operation information and the detection information in other periods may be analyzed. When performing the correlation analysis, the information analysis unit 142 may add other information having a correlation with the user's life pattern as a condition of another period adopted for the analysis of the correlation with the motion information. For example, the information analysis unit 142 acquires weather information indicating the weather (for example, at least distinction between fine weather, rainy weather, and cloudy weather) in other periods that do not correspond to the information unavailable period via the network, and each of the information unavailable periods. Detection information at a time point having the same phase as the time point and with the same weather may be adopted. For example, if the detection information is missing on a recent rainy Tuesday, the weather on the Tuesday one week before is fine, and the weather on the Tuesday two weeks before is rainy, the Information Analysis Department 142 will tell you the latest Tuesday. As the detection information used for the analysis of the correlation with the operation information of, the detection information of Tuesday two weeks ago is adopted. In addition, when there are a plurality of periods that satisfy the weather conditions, the information analysis unit 142 makes a linear prediction from statistical representative values such as the average of the detected information in those plurality of periods and these detected information. The predicted value in the information unavailable period obtained by using a method such as may be adopted. Further, the other period different from the information unavailability period may be a period preceding the information unavailability period related to the detection information or the operation information to be analyzed as illustrated, but the information cannot be used. It may be a period later than the period. Alternatively, although it is not normally used mainly, other types of detection information such as a motion sensor can also be acquired from the other second device 30, and the information analysis unit 142 describes the information unavailable period of the main detection information. Instead of the main detection information, the correlation with the operation information may be analyzed using other types of detection information that can be acquired.

Then, the analysis result utilization unit 60 accumulates the number of viewers who have viewed the broadcast program for each attribute among the content presenting devices 40, calculates the number of viewers by attribute, and totals the total number of viewers by attribute. Calculated as the number of people. The analysis result utilization unit 60 can determine the ratio of the number of viewers by attribute for each attribute to the total number of viewers as an attribute distribution.

Further, the analysis result utilization unit 60 is associated with viewing channel information indicating a predetermined viewing channel for each time zone of a predetermined time interval (for example, 10 to 60 minutes), and indicates the viewing time including the time zone. For each group related to the viewing time information, the number of users indicated by the estimated user information and the number of cases (that is, 1) in the group may be accumulated and calculated as the total number of viewers and the total number of viewings, respectively. The analysis result utilization unit 60 may generate viewing analysis information illustrating the total number of viewers and the total number of viewings for each time zone.

You may judge. The advertising data may include, for example, the same video and audio as the advertising program, or the video and audio separate from the advertising program, but may include video and audio including common products, services and other guidance information. Good. The analysis result utilization unit 60 transmits the advertisement data to the mobile phones of the users who have not watched the advertisement program among the registered users registered in advance via the network NW. The analysis result utilization unit 60 refers to the user registration information, and indicates the viewing channel information indicating the broadcasting channel of the advertising program and the viewing time including a part or all of the broadcasting time in the acquired analysis result information. A group other than the group related to the television receiver containing the information is specified as the distribution target group. The analysis result utilization unit 60 may refer to the user registration information and specify the advertisement identification information or the device identification information of the mobile phone for each user associated with the group identification information indicating the specified distribution target group as the transmission destination. it can.

The analysis result utilization unit 60 may transmit predetermined advertisement data including information related to the genre to each mobile phone of the viewer who has watched the broadcast program of the predetermined genre (for example, travel). The analysis result utilization unit 60 refers to the user registration information, and in the acquired analysis result information, the viewing channel information indicating the broadcasting channel of the broadcast program and the viewing time indicating a viewing time including a part or all of the broadcasting time. The group identification information that indicates the group related to the television receiver including the information as the distribution target group is specified. The analysis result utilization unit 60 refers to the user registration information, and among the device identification information of the mobile phone for each user associated with the specified group identification information, the detection information corresponding to the viewing channel information and the viewing time information is used. The device identification information included or the advertisement identification information associated with the device identification information can be specified as a transmission destination.
Even if the analysis result utilization unit 60 transmits information related to the advertisement program (for example, information related to the product or service advertised in the advertisement program) to each mobile phone of the viewer who has viewed the predetermined advertisement program. Good. The analysis result utilization unit 60 views the corners (segments) that are a part of the broadcast program and the scenes that are more subdivided than the corners, instead of specifying the viewers in units of the broadcast program. You may identify the person.
