Communication is performed between the device 40 and the SM server device 70.

  The IM server device 40 is a server device that provides event metadata to the event evaluation device 30. The event metadata is data in which an event scheduled time zone in which an event is scheduled is associated with event specifying information for specifying the event. The event in this embodiment is a program broadcast by a television broadcasting station. The event metadata may be data extracted from an EPG (Electronic Program Guide), or may be data in which an operator who has viewed a program describes items related to the program in an XML (Extensible Markup Language) format. Here, an example of EPG will be described. The storage unit of the IM server device 40 stores an EPG created based on data provided from each television broadcast company. When receiving a request for event metadata from the event evaluation device 30, the IM server device 40 extracts event metadata corresponding to the request from the stored EPG and transmits the event metadata to the event evaluation device 30.

FIG. 5 is a diagram showing event metadata. The event metadata is data in which an event name, an event channel ID (Identification), an event ID, and an event scheduled time zone are associated with each event.
The event name is the name of the event, and is the program name in the present embodiment. In the case of a continuous program, the event names are different for each broadcast, such as “15th person who can change” and “16th person who can change”.
The event channel ID is an identifier for identifying a medium or a place used for providing an event, and is an identifier assigned to each channel of the television in this embodiment.
The event ID is an identifier assigned to each event.
The scheduled event time zone is a time zone in which an event is scheduled, and in this embodiment, includes the scheduled broadcast date, scheduled start time, and scheduled end time of the program.
Of the event metadata described above, the event name, event channel ID, and event ID are event specifying information for specifying an event. Among these, the event channel ID alone does not specify an event, but the event is specified by a combination of the event channel ID and the scheduled event time zone.

The SM server device 70 is a server device that provides services such as social media, that is, mini-blogs, blogs, social networking services, electronic bulletin boards, and the like. In this embodiment, an example of a miniblog will be described. When a user registers in the SM server device 70 as a service user, the user is allowed to post to the miniblog. The storage unit of the SM server device 70 stores a database that accumulates posted text. When a user posts a text to the SM server device 70 using the terminal device 20, the text and the posting time that is the time when the text is received by the SM server device 70 are associated and written to the database, and the text is written. The included HTML (HyperText Markup Language) data is returned to the terminal device 20. As a result, the text is displayed on the display unit of the terminal device 20. When the user registers another user, the text posted by the other user is also transmitted to the terminal device 20. When there are a plurality of texts to be displayed, these texts are displayed side by side in descending order of posting time.
When receiving a request for social media data from the event evaluation device 30, the SM server device 70 extracts social media data that matches the request from the database and transmits the social media data to the event evaluation device 30.

The text ID is an identifier assigned to each text.
The user ID is an identifier assigned to the user who transmitted each text.
The posted content includes posted text and a target identification keyword associated with the text. The target identification keyword is, for example, a hash tag in Twitter (registered trademark), and is information for identifying a posting target. For example, in the case of text ID = 40001 in the figure, the text “posted by a person who can change” is posted, and the character string “tbf” following “#” is the target identification keyword. “Tbf” is an example of an abbreviation for broadcasting station. As described above, a relatively simple character string of the alphabet is frequently used as the target identification keyword.
The posting time is the time when the text is received by the SM server device 70.

FIG. 3 is a block diagram illustrating a functional configuration of the event evaluation device 30. When the control unit 31 executes the program stored in the storage unit 32, the following functions are realized.
The event metadata acquisition unit 301 acquires event metadata in which an event scheduled time zone in which an event is scheduled is associated with event specifying information for specifying the event.

  Based on the event metadata acquired by the event metadata acquisition unit 301, the text acquisition unit 303 acquires the text corresponding to the event identification information from the text posted in the scheduled event time zone. The text acquisition unit 303 acquires a text corresponding to the event specifying information and a posting time when the text is posted.

  Based on the number of texts acquired by the text acquisition unit 303, the exposure amount calculation unit 304 calculates an exposure amount representing the amount of exposure of the event to the public. Specifically, the exposure amount calculation unit 304 extends from a scheduled start time of the scheduled event time zone to a first time zone shorter than the planned event time zone in the text acquired by the text acquisition unit 303. The number of posted texts is calculated as the exposure amount.

  The reaction amount calculation means 305 divides the scheduled event time zone into second time zones shorter than the scheduled event time zone, and sets the number of posted texts for each second time zone as the event. On the other hand, it is calculated as a reaction amount representing the amount of reaction of the public.

  The degree of interest calculation means 306 is a degree that the public interest is aroused by the event based on the exposure amount calculated by the exposure amount calculation means 304 and the reaction amount calculated by the reaction amount calculation means 305. Is calculated for each second time period.

<Operation of First Embodiment>
FIG. 4 is a flowchart showing the operation of the event evaluation device 30. The control unit 31 executes the following process according to the program stored in the storage unit 32. This process is executed when the user of the terminal device 20 instructs the event evaluation device 30 to evaluate the event using the terminal device 20. Specifically, the user starts a browser on the terminal device 20 and accesses the event evaluation device 30. Then, the event evaluation device 30 acquires an EPG from the IM server device 40 and transfers this EPG to the terminal device 20. The terminal device 20 displays the EPG received from the IM server device 40 on the display unit. The user designates one of the programs being broadcast among the programs included in the EPG, and transmits an instruction to the event evaluation device 30 to evaluate the program. When receiving this instruction, the control unit 31 executes the following processing.

  In step S <b> 101, the control unit 31 acquires event metadata by using the function as the event metadata acquisition unit 301. Specifically, the control unit 31 requests the IM server device 40 for event metadata corresponding to the instruction received from the terminal device 20. The control unit of the IM server device 40 extracts the event metadata requested by the event evaluation device 30 from the EPG stored in the storage unit, and transmits the extracted event metadata to the event evaluation device 30. The control unit 31 stores the received event metadata in the storage unit 32. Here, it is assumed that the event metadata corresponding to the event name “Fifteenth Changeable Person” is acquired from the event metadata shown in FIG.

  In step S102, the control unit 31 determines the search condition based on the event metadata by the function as the search condition determination unit 302. Specifically, the search condition includes an event scheduled time zone and a target identification keyword. Since the text posted to the SM server device 70 is associated with the target identification keyword, the text can be narrowed down using the target identification keyword as a search condition. On the other hand, the event metadata includes an event name, an event channel ID, and an event ID as event specifying information for specifying an event, but a relatively simple alphabetic character string is frequently used as a target identification keyword. Therefore, there are few cases where the event name itself is used as a target identification keyword. Since the event ID is not open to the public, it is not used as a target identification keyword. Although the event channel ID itself is not used as a target identification keyword, for example, an event is specified by a combination of an abbreviation of a television station corresponding to the event channel ID and a scheduled event time zone. Accordingly, the event channel ID and the TV station abbreviation are associated with each other and stored in the storage unit 32 in advance, and the control unit 31 sets the TV station abbreviation corresponding to the event channel ID included in the event metadata acquired in step S101. Read from the storage unit 32. This abbreviation is a target identification keyword. 5 and 6 show an example in which the target identification keyword corresponding to the event channel ID “1” is “tbf”. In this example, the search condition is that the scheduled event time zone is “2011/3/3 12: 00-13: 00” and the target identification keyword is “tbf”.

  In step S <b> 103, the control unit 31 acquires text that matches the search condition by using the function as the text acquisition unit 303. Specifically, the control unit 31 requests the SM server device 70 to extract text that matches the search condition determined in step S102. The SM server device 70 searches the database according to the search condition, extracts the text that matches the search condition and the posting time of the text, and transmits the extracted text to the event evaluation device 30. The control unit 31 stores the received text and the posting time in the storage unit 32 in association with each other. In this example, among the social media data shown in FIG. 6, the text corresponding to the scheduled event time zone “2011/3/3 12: 00-13: 00” and the target identification keyword “tbf” and the posting time are To be acquired.

  In step S <b> 104, the control unit 31 extracts text posted in the first time zone by using the function as the exposure amount calculation unit 304. The first time zone is, for example, 5 minutes from the scheduled start time of the program. The control unit 31 extracts text whose posting time is included in the first time zone from the text received in step S103.

  In step S <b> 105, the control unit 31 calculates the exposure amount of the event by the function as the exposure amount calculation unit 304. Specifically, the control unit 31 calculates the number of texts extracted in step S104. The number calculated in this way is an exposure amount representing the amount of the event exposed to the public.

  In step S <b> 106, the control unit 31 extracts text for each second time zone by using the function as the reaction amount calculation unit 305. The length of the second time zone is, for example, 1 minute. The control unit 31 divides the scheduled event time zone into time zones of 1 minute, and extracts the text including the posting time in the time zone in each time zone from the text received in step S103.

  In step S <b> 107, the control unit 31 calculates a reaction amount by the function as the reaction amount calculation unit 305. Specifically, the control unit 31 calculates the number of texts for each second time period extracted in step S106. The number for each second time period calculated in this way is a reaction amount that represents the amount that the public has reacted to the event. FIG. 7 is a diagram showing the calculated reaction amount.

  In step S <b> 108, the control unit 31 calculates the degree of interest by using the function as the degree of interest calculation unit 306. Specifically, the control unit 31 divides the reaction amount for each second time period by the exposure amount. The value calculated in this way is the degree of interest that represents the degree of public interest that has been aroused by the event. FIG. 8 is a diagram showing the calculated interest level.

  In step S <b> 109, the control unit 31 outputs the degree of interest by using the function as the degree of interest calculation unit 306. Specifically, the control unit 31 generates HTML data including a numerical value of the degree of interest and transmits it to the terminal device 20. The control unit of the terminal device 20 displays an image based on the received HTML data on the display unit. This HTML data may display the numerical value of the interest level itself, or may display the numerical value as a graph. Alternatively, a threshold for the degree of interest may be set in advance, and if the degree of interest exceeds this threshold, a message indicating that the program has a high audience rating may be displayed.

The effects of this embodiment are as follows.
The event evaluation device 30 according to the present embodiment acquires event metadata in which an event scheduled time zone and event identification information are associated, and among texts posted on a social media website during the event scheduled time zone, A text corresponding to the event identification information is acquired, and an exposure amount representing the amount of the event exposed to the public is calculated based on the acquired number of texts. Therefore, the exposure amount can be measured without providing a device for measuring the exposure amount on the public side. The text may be acquired during the scheduled event time zone. In this case, since the exposure amount can be measured in parallel with the exposure of the event in time, the user can determine whether or not the event is provided during the event.

  In addition, the event evaluation device 30 according to the present embodiment exposes the number of texts posted over the first time period shorter than the scheduled event time period from the scheduled start time of the scheduled event time period among the acquired texts. Calculate as a quantity. The content of the text posted on social media during the first 5 minutes of the broadcast of the program, for example, informs the fact that you are watching the program, as shown in Figure 6. There are many. That is, the number of texts posted in the first time zone can be an index representing the amount of events exposed to the public. Therefore, according to the present embodiment, a highly reliable exposure amount can be calculated.

  Further, the event evaluation device 30 according to the present embodiment divides the scheduled event time zone into second time zones that are shorter than the scheduled event time zone, and the text posted on the website for each second time zone. The number is calculated as a reaction amount that represents the amount that the public has reacted to the event, and the degree of interest that represents the degree of public interest caused by the event based on the exposure amount and the reaction amount is calculated for the second time. It is configured to calculate for each band. The text posted to social media during the course of the program includes a user who posted the text during the first time zone and expressed an impression of the program, or a user who did not watch the program during the first time zone May contain various texts, such as those that know the reputation of the program through social media or so-called word-of-mouth, and describe the impression when you started watching the program. It shows the reaction of the viewer. That is, the number of texts posted on social media for each second time period can be an index representing the amount of public response to the event.

  Furthermore, the reaction amount obtained in this way is compared with the exposure amount, thereby obtaining an index representing the degree of public interest caused by the event. For example, the exposure amount of program A is 40, the reaction amount of program A in a certain time zone is 10, the exposure amount of program B is 30, and the reaction amount of program B in a certain time zone is 15. If so, the degree of interest in programs A and B is 0.25 and 0.5, respectively, and program B has an evaluation that the degree of interest is higher than that of program A. Thus, according to the present embodiment, it is possible to obtain the degree of interest that represents the degree of public interest that has been aroused by the event. Also, if the text is acquired during the scheduled event time, the degree of interest can be measured in parallel with the exposure of the event, so whether or not the event is provided. The user can make decisions while the event is in progress.

<Configuration of Second Embodiment>
The second embodiment of the present invention will be described while referring to differences from the first embodiment. In addition, the code | symbol used in 1st Embodiment was described about the step of the same component as 1st Embodiment and the same processing content.
FIG. 9 is a diagram showing the entire event evaluation system 2 according to the second embodiment of the present invention. The event evaluation system 2 includes an event evaluation device 80 instead of the event evaluation device 30 of the first embodiment.
FIG. 10 is a diagram illustrating a hardware configuration of the event evaluation device 80. The configurations of the control unit 81, the storage unit 82, and the communication unit 83 are the same as those of the control unit 31, the storage unit 32, and the communication unit 33 of the first embodiment.

FIG. 11 is a block diagram showing a functional configuration of the event evaluation device 80. When the control unit 81 executes the program stored in the storage unit 82, the following functions are realized.
The event metadata acquisition unit 801 acquires event metadata in which an event scheduled time zone in which an event is scheduled and event specifying information for specifying the event are associated with each other.

  Based on the event metadata acquired by the event metadata acquisition unit 801, the user ID acquisition unit 803 includes the user ID associated with the text posted in the scheduled event time zone as the event identification information. The user ID associated with the corresponding text is acquired. Further, the user ID acquisition unit 803 acquires a user ID associated with a text corresponding to the event specifying information and a posting time when the text is posted.

  Based on the number of unique users calculated from the user ID acquired by the user ID acquisition unit 803, the exposure amount calculation unit 804 calculates an exposure amount representing the amount of exposure of the event to the public. Specifically, the exposure amount calculation unit 804 determines, based on the user ID acquired by the user ID acquisition unit 803, a first time period shorter than the scheduled event time period from the scheduled start time of the scheduled event time period. The number of unique users corresponding to the posted text is calculated as the exposure amount. The number of unique users is calculated by setting the number of user IDs to 1 when there are a plurality of identical user IDs among user IDs corresponding to text posted over the first time period. For example, the first user ID in the data string of user IDs is used as a reference value, and the same user ID as this reference value is extracted, and the extracted user ID is deleted from the data string. After this process is executed using each user ID as a reference value in order from the top of the data string, the number of user IDs remaining in the data string is obtained. This number is the number of unique users.

  The reaction amount calculation means 805 divides the scheduled event time zone into second time zones shorter than the scheduled event time zone, and the number of unique users corresponding to the posted text for each second time zone. Is calculated as a reaction amount representing the amount of reaction of the public to the event. The number of unique users is calculated by setting the number of user IDs to 1 when there are a plurality of identical user IDs among the user IDs corresponding to the posted text for each second time period. .

  The degree of interest calculation means 806 is the degree to which the public's interest is aroused by the event based on the exposure amount calculated by the exposure amount calculation means 804 and the reaction amount calculated by the reaction amount calculation means 805. Is calculated for each second time period.

  In step S <b> 203, the control unit 81 acquires text that matches the search condition by using the function as the user ID acquisition unit 803. Specifically, the control unit 81 requests the SM server device 70 to extract the user ID associated with the text that matches the search condition determined in step S102. The SM server device 70 searches the database according to the search condition, extracts the user ID associated with the text that matches the search condition and the posting time of the text, and transmits the extracted user ID to the event evaluation device 30. The control unit 31 stores the received user ID and the posting time in the storage unit 32 in association with each other.

  In step S204, the control unit 81 extracts a user ID associated with the text posted in the first time zone by using the function as the exposure amount calculating unit 804. The first time zone is, for example, 5 minutes from the scheduled start time of the program. The control unit 31 extracts the user ID corresponding to the posting time corresponding to 5 minutes from the scheduled start time of the program from the user ID received in step S203.

  In step S205, the control unit 81 calculates the exposure amount of the event by using the function as the exposure amount calculation unit 804. Specifically, the control unit 81 calculates the number of unique users from the user ID extracted in step S204. The number calculated in this way is an exposure amount representing the amount of the event exposed to the public.

  In step S206, the control unit 81 extracts a user ID for each second time zone by using the function as the reaction amount calculation unit 805. The control unit 81 divides the scheduled event time zone into time zones of one minute, and extracts the user ID corresponding to the posting time corresponding to each time zone from the user ID received in step S203.

  In step S207, the control unit 81 calculates a reaction amount by the function as the reaction amount calculation unit 805. Specifically, the control unit 81 calculates the number of unique users from the user ID for each second time period extracted in step S206. The number for each second time period calculated in this way is a reaction amount that represents the amount that the public has reacted to the event.

In step S <b> 208, the control unit 81 calculates the degree of interest by using the function as the degree of interest calculation unit 806. The contents of the processing are the same as those in the first embodiment.
In step S209, the control unit 81 outputs the degree of interest by using the function as the degree of interest calculation unit 806. The contents of the processing are the same as those in the first embodiment.

The effects of this embodiment are as follows.
The event evaluation device 30 according to the present embodiment acquires event metadata in which an event scheduled time zone and event specifying information are associated with each other, and associates it with text posted on a social media website during the event scheduled time zone. The user ID associated with the text corresponding to the event identification information is acquired from the acquired user ID, and the amount of the event exposed to the public is calculated based on the number of unique users calculated from the acquired user ID. The exposure amount to be expressed is configured to be calculated. Therefore, according to the present embodiment, it is possible to eliminate the influence of a user who posts a plurality of texts and to measure the exposure amount more accurately. Further, the exposure amount can be measured without providing a device for measuring the exposure amount on the public side.
