The search keyword extraction unit 106d outputs information related to the search keyword to the client terminal 50.

  The viewing status management unit 106e is means for monitoring the viewing status of the user with respect to the television program and updating the viewing status management table 105e. For example, in the viewing status management unit 106e, the program distribution processing unit 106b sends the television program with the program identification number “1003” to the client terminal used by the user with the user identification number “2001” from “July 10, 18:05 to In the case of distribution until “July 10 18:45”, the information shown in the first row of the viewing status management table 105e in FIG. 8 is registered.

  In addition, the viewing status management unit 106e compares the user identification number, the program identification number, the input keyword management table 105c, and the search keyword management table 105d, and determines whether the user took a viewing action while viewing the TV program. Determine whether or not. The viewing status management unit 106e sets the viewing behavior flag to ON when it is determined that the user has performed viewing behavior while viewing the television. Note that the initial setting of the viewing behavior flag is off.

  Here, the process in which the viewing status management unit 106e determines the viewing behavior of the user will be specifically described. The viewing status management unit 106e first refers to each stage of the viewing status management table 105e, extracts the combination of the user identification number and the program identification number, and combines the extracted user identification number and the program identification number. Is present in the search keyword management table 105d. When the combination of the user identification number and the program identification number exists in the search keyword management table 105d, the viewing state management unit 106e determines that the user has taken a viewing action while viewing the television program.

  For example, the viewing status management unit 106e extracts the user identification number “2001” and the program identification number “1003” from the viewing status management table 105e (see the first row in FIG. 8), and sets the search keyword management table 105d. Referring to it, there is a combination of the user identification number “2001” and the program identification number “1003” (see the first row in FIG. 7). Accordingly, the viewing status management unit 106e determines that the viewing behavior has occurred while the user (the user with the user identification number “2001”) is viewing the television program (the television program with the program identification number “1003”).

  When the viewing status management unit 106e determines that the user does not take a viewing action while watching the TV program by comparing with the search keyword management table 105d, the viewing status management unit 106e compares the search keyword management table 105d with the input keyword management table 105c. It is determined again whether or not the viewing behavior has occurred during the viewing of the TV program.

  The viewing state management unit 106e determines whether the combination of the user identification number and the program identification number exists in the input keyword management table 105c and the relevance determination result is “1”. When the combination of the user identification number and the program identification number exists in the input keyword management table 105c and the relevance determination result is “1”, the viewing state management unit 106e determines that the user It is determined that the viewing behavior has occurred while watching.

  For example, the combination of the user identification number “2002” and the program identification number “1001” exists in the input keyword management table 105c, and the relevance determination result corresponding to the combination is “1” (FIG. (Refer to the third row of 6). Therefore, it is determined that the user (the user with the user identification number “2002”) took a viewing action while viewing the television program (the television program with the program identification number “1001”).

  The relevancy determination processing unit 106f calculates the similarity based on the television program information management table 105b and the input keyword management table 105c, and the input keyword input by the user during viewing of the program based on the calculated similarity is viewed. It is a means to determine whether it is related to the television program in the inside.

  Specifically, the relevancy determination processing unit 106f extracts the input keyword to be determined and the corresponding program identification number from the input keyword management table 105c, and various pieces of information on the TV program corresponding to the extracted program identification number. (Eg, program name, genre, performer, program description) are extracted from the TV program information management table 105b.

  Then, morphological analysis is performed on various pieces of information of the television program to divide the information into keywords, and the similarity between each keyword and the input keyword is calculated. Here, any known technique may be used as a method for calculating the similarity. For example, each keyword and input keyword may be converted into a vector, and the similarity between the input keyword and each keyword may be calculated using a cosine method or the like. Alternatively, the similarity may be calculated by calculating the distance between two words based on parameters obtained from the co-occurrence information of the thesaurus and corpus data (see, for example, JP-A-2005-38162). ).

  The relevance determination processing unit 106f sets the relevance determination result corresponding to the input keyword to “1” when the similarity between each keyword of the TV program and the input keyword is a predetermined value or less, and is less than the predetermined value. In this case, the relevance determination result corresponding to the input keyword is set to “0”.

  The viewing behavior rate calculation unit 106g is a means for calculating the viewing behavior rate and the viewing rate based on the viewing status management table 105e and registering the calculation result in the viewing rate calculation result data 105f. When calculating the viewing behavior rate, the viewing behavior rate calculating unit 106g refers to the viewing status management table 105e and actually watches the user with the user identification number whose viewing behavior flag is on. Counting as viewers, the viewing behavior rate is calculated from the ratio between the counted viewers and the total viewers (viewers of each program).

  Further, the viewing behavior rate calculation unit 106g refers to the viewing status management table 105e, counts the viewers of the TV program, not only the viewing behavior flag on / off, and the ratio between the counted viewers and the total viewers To calculate the audience rating.

Next, a processing procedure of the viewing behavior rate calculating apparatus 100 according to the present embodiment will be described. FIG. 10 is a flowchart illustrating the processing procedure of the viewing behavior rate calculating apparatus 100 according to the present embodiment. As shown in FIG. 10, the viewing behavior rate calculating apparatus 100 receives a service request from the client terminal 50 (step S101), and the program distribution processing unit 106b distributes the television program (step S102).

  Then, the search keyword extraction unit 106d determines whether or not a search keyword has been selected (step S103). If no search keyword has been selected (step S104, No), the process proceeds to step S106.

  On the other hand, when the search keyword is selected (step S104, Yes), the search keyword extraction unit 106d updates the search keyword management table 105d (step S105), and the input keyword extraction unit 106c receives the input keyword. It is determined whether or not (step S106).

  If the input keyword has not been input (No at Step S107), the process proceeds to Step S109. On the other hand, when an input keyword is input (step S107, Yes), the input keyword extraction unit 106c updates the input keyword management table 105c (step S108).

  Then, the program distribution processing unit 106b determines whether or not the distribution of the television program has ended (step S109). If the distribution has not ended (step S110, No), the distribution of the television program is continued (step S109). S111), the process proceeds to step S103.

  On the other hand, when the distribution of the TV program is finished (step S110, Yes), the program distribution processing unit 106b stops the distribution of the TV program (step S112), and the viewing state management unit 106e stores the viewing state management table 105e. Update (step S113).

  The relevance determination processing unit 106f determines the relevance of the input keyword in the input keyword management table 105c, registers the determination result (step S114), and the viewing behavior rate calculation unit 106g calculates the viewing rate and the viewing behavior rate. (Step S115).

As described above, the viewing activity rate calculating apparatus 100 according to the present embodiment uses the widget function while delivering TV program data in response to a request from a client terminal (a user selects a TV program). Information on whether or not the user has searched for a keyword related to the content of the television program being distributed is acquired. Then, the viewing activity rate calculating apparatus 100 counts only users who have searched for keywords related to the contents of the TV program among all users who are watching the TV program as viewers who actually viewed the TV program, Since the viewing behavior rate of the program is calculated, users who are not actually watching the television program can be excluded from the viewer, and as a result, an accurate viewing behavior rate can be calculated.

Note that an audience rating calculation program describing the audience rating calculation method of the audience activity rate calculating apparatus 100 described in the above embodiment in a computer-executable format is generated, and the audience rating calculation program is executed by the computer. It is also possible to realize processing similar to that of the television analysis device 100 of the present invention. At this time, the audience rating calculation program can be stored in a computer-readable storage medium, and the audience rating calculation program can be introduced into the computer using the storage medium.
