<Outline of recommendation system 1>
The recommendation system 1 in 1st Embodiment to which this invention is applied is demonstrated. As shown in FIG. 1, the recommendation system 1 includes a browser terminal 100, a first Web server 300, a second Web server 200, a karaoke device 400, a database server 500, and a calculation PC 600. The browser terminal 100, the Web server 300, and the Web server 200 are connected via a WAN (Wide Area Network). The Web server 300, the karaoke device 400, the database server 500, and the calculation PC 600 are connected via a LAN (Local Area Network).

  The recommendation system 1 according to the present embodiment displays a web page on which an advertisement corresponding to the time ID of the consumer M is placed when the consumer M uses the browser terminal 100 to access a member-dedicated website. This is a system for displaying to the consumer M. In addition, the recommendation system 1 of this embodiment has memorize | stored the data which shows when an advertisement presentation is started for every time ID, and provides an advertisement based on the data. For this reason, an advertisement is provided at a timing suitable for the time ID of the consumer M.

  The consumer M who is a member of the recommendation system 1 is based on the innovator theory (Everett M. Rogers, 1962), and 5 of “Innovator”, “Early Adopter”, “Early Majority”, “Late Majority”, “Lagard” It is pre-classified into one group. The time ID is an ID indicating which of the above five groups the consumer M belongs to. In recommendation system 1 of this embodiment, time ID of consumer M is defined based on the below-mentioned song history.

  “1” is assigned as the time ID to the consumer M belonging to “innovator”. A time ID “2” is assigned to the consumer M belonging to “Early Adopter”. A time ID “3” is assigned to the consumer M belonging to “early majority”. A time ID “4” is assigned to the consumer M who belongs to “Late Majority”. A time ID “5” is assigned to the consumer M belonging to “Lagard”.

  Examples of Web pages displayed on the browser terminal 100 of the consumer M are shown in FIGS. When the consumer M inputs a predetermined address and accesses the member-dedicated website, a login page as shown in FIG. 2 is displayed on the browser terminal 100. FIG. 2 shows an example of a login page of a member-only website “Serious video posting.com”. On the login page, an input box 10 for inputting a user ID (hereinafter referred to as UID), an input box 20 for inputting a password, and a login button 30 for logging in are displayed.

  When the consumer M inputs the UID in the input box 10 and the password in the input box 20 and then clicks on the login button 30, the member TOP page, which is the page after login, is displayed on the browser terminal 100.

  An example of the member TOP page is shown in FIG. In the example of the member TOP page shown in FIG. 3, information for members A to D is displayed as information for members. Moreover, the advertisement image of the product A is displayed as an example of the advertisement image. The advertisement image is an advertisement corresponding to the time ID of the consumer M who is a user of the browser terminal 100.

  When the consumer M clicks on the advertisement image in the advertisement column, an advertisement page is displayed on the browser terminal 100. An advertisement page is a page which introduces the product of the advertisement published on the member TOP page. The consumer M can perform processing for purchasing a product on this advertisement page.

  Next, the operation of each device in the recommendation system 1 will be briefly described. When the consumer M enters the UID and password on the login page and accesses the member TOP page, the first Web server 300 displays HTML of the member TOP page on which an advertisement image corresponding to the consumer M's time ID is placed. A file is created, and the HTML file is transmitted to the browser terminal 100 of the consumer M. As a result, an advertisement image suitable for the time ID of the consumer M is provided to the consumer M.

  The second Web server 200 stores an advertisement image that is an image of an advertisement placed on the member TOP page. In the HTML text of the member TOP page, the URI of the advertisement image stored in the Web server 200 is described. When the browser terminal 100 performs rendering based on this URI, the advertisement image stored in the Web server 200 is displayed at a predetermined position on the member TOP page.

  When the advertisement image on the member TOP page is clicked by the consumer M, the advertisement page is displayed on the browser terminal 100. The Web server 300 transmits the HTML file of the advertisement page to the browser terminal 100 when the advertisement image is clicked.

  In order for the recommendation system 1 to provide an advertisement image suitable for the consumer M based on the UID input by the consumer M, data for determining which time ID corresponds to the UID; It is necessary to store data for determining which advertisement image corresponds to the time ID. The database server 500 stores these data.

  Regarding which time ID is set for the consumer M, the recommendation system 1 performs based on the singing behavior history acquired by the karaoke apparatus 400. Although the details will be described later, the singing action history stores the ID of the music, the UID of the consumer M who sang the music, the date of singing, and the date when the distribution of the music was started. And based on this singing history, which time ID is set for the consumer M is determined. The singing action history acquired by the karaoke apparatus 400 is stored in the database server 500 at a predetermined timing.

  The calculation PC 600 is a PC used by the administrator of the recommendation system 1 and is used when data stored in the database server 500 is updated.

  Detailed operation of the recommendation system 1 will be described later.

  Next, details of the database update process performed in S305 described above will be described with reference to FIG.

  When the database update process is started, control unit 510 determines whether or not a singing history transmission request has been received in S300 described above (S311).

  When the transmission request | requirement of a song history is received (S311: Yes), the song history memorize | stored in the song history storage area | region 589 is transmitted to PC600 for calculation (S312). The singing history is acquired from the karaoke apparatus 400 in advance. When the consumer M sings with the karaoke apparatus 400, the user M logs in by inputting his / her UID into the karaoke apparatus 400. And when the consumer M sings a predetermined music, the karaoke apparatus 400, the music ID for identifying the music that has been sung, the UID of the consumer M, and the singing action date that is the date on which the singing was performed And the song log which matched the delivery start date which is the date on which the delivery of the music was started is memorize | stored. And the karaoke apparatus 400 transmits the song log to the database server 500 at a predetermined timing. The database server 500 that has received the singing log updates the singing history based on the received singing log. Specifically, the database server 500 updates the singing history through other processing (S322) described later. After transmitting the singing history to PC 600 for calculation, control unit 510 performs the process of S300 described above.

  When the received data is not a singing history update request (S311: No), it is determined whether the data received in S300 is a UID_time ID table update request (S313).

  If the received data is a UID_time ID table update request (S313: Yes), the table stored in the UID_time ID table storage area 583 is received from the calculation PC 600 together with the UID_time ID table update request. The UID_time ID table is updated (S314), and the process returns to S300 described above.

  If an update request for the UID_time ID table has not been received (S313: No), it is determined whether the data received in S300 is a click log (S315).

  If it is a click log (S315: Yes), the click history stored in the click history storage area 585 is updated (S316). Then, after updating the click history, a click history update completion notification is transmitted to the Web server 300 (S317), and the process returns to S300 described above.

  If it is not a click log (S315: No), it is determined whether or not the data received in S300 is a transmission request for a click history, a UID_time ID table, and an advertisement ID_propagation date table (S318).

  When the transmission request is a click history or the like (S318: Yes), the click history, UID_time stored in the click history storage area 585, the UID_time ID table storage area 583, and the advertisement ID_propagation date table storage area 588, respectively. The ID table and the advertisement ID_propagation date table are transmitted to the calculation PC 600 (S319), and the process returns to S300 described above.

  If it is not a transmission request such as a click history (S318: No), it is determined whether or not the data received in S300 described above is a request for updating the time ID_advertisement ID table (S320).

  When it is a request for updating the time ID_advertisement ID table (S320: Yes), in S300, the time ID_advertisement ID table is added to the new time ID_advertisement ID table received from the calculation PC 600 together with the request for updating the time ID_advertisement ID table. The table in the table storage area 584 is updated (S321), and the process returns to S300 described above.

  If it is not an update request for the time ID_advertisement ID table (S320: No), other processing is performed (S322), and the process returns to S300. In S322, the above-described singing history is updated. In addition, the advertisement ID_advertisement image URI table, advertisement ID_advertisement page address table, advertisement ID_propagation date table, and the like are also updated. These updates may be performed according to the request from the calculation PC 600, or the database server 500 can be accessed from the PC of the person in charge of the advertisement distribution company so that the person in charge of the advertisement distribution company can update. It may be.

<Operation of PC 600 for calculation>
A calculation PC process performed by the control unit 610 of the calculation PC 600 will be described with reference to FIGS. The control unit 610 performs a calculation PC process according to the OS and the activated database update program.

  In the calculation PC 600, when the database update program is activated, the control unit 610 starts the calculation PC program. When the administrator operates the input device 640 to perform input, the control unit 610 stores data indicating what operation has been performed in the work area of the RAM (S400). For example, when the administrator operates the input device 640 to instruct updating of the UID_time ID table, data indicating an instruction to update the UID_time ID table is stored in S400. For example, when the administrator operates the input device 640 to instruct an update of the time ID_advertisement ID table, data indicating an instruction to update the time ID_advertisement ID table is stored in S400.

  Next, it is determined whether the data stored in S400 is data indicating an instruction to update the UID_time ID table (S401).

  If it is an instruction to update the UID_time ID table (S401: Yes), update processing of the UID_time ID table described later is performed (S402).

  If it is not an instruction to update the UID_time ID table (S401: No), it is determined whether or not the data stored in S400 is an instruction to update the time ID_advertisement ID table (S403).

  If it is an instruction to update the time ID_advertisement ID table (S403: Yes), update processing of the later-described time ID_advertisement ID table is performed (S404).

  If it is not an instruction to update the time ID_advertisement ID table (S403: No), other processing is performed (S405). For example, processing for updating an advertisement ID_advertisement image URI table, an advertisement ID_advertisement page address table, an advertisement ID_propagation date table, and the like are performed.

  After performing the above-described S402, S404, and S405, the control unit 610 determines whether or not an operation for stopping the database update program has been performed by the administrator (S406), and when the operation for stopping has not been performed. (S406: NO), it returns to S400. If a stop operation has been performed (S406: Yes), the database update program is stopped and the calculation PC process is terminated.

  Next, the details of the UID_time ID table update process performed in S402 described above will be described with reference to FIG.

  When the update process of the UID_time ID table is started, the control unit 610 transmits a singing history transmission request to the database server 500 (S411).

  After transmitting the singing history transmission request (S411), it is determined whether or not the singing history is received from the database server 500 (S412). When the singing history is not received, it waits until it receives the singing history (S412: No).

  When the singing history is received from the database server 500 (S412: Yes), a new UID_time ID table is created based on the received singing history (S413). Here, various methods can be considered for creating the UID_time ID table. As an example, it is considered that the average value of the period from the distribution start date of the singing history to the singing action date is calculated for each UID, and the time IDs are sequentially allocated from “1” in the shortest period based on the calculated value. It is done.

  As another example, the elapsed time from the distribution start date is divided into a plurality of periods, the number of times the consumer sings is counted for each period, and this is used as a vector configuration of the UID, which is a well-known clustering technique. You may classify | categorize into five groups from which consumption action time differs mutually by SOM analysis. Specifically, the first period from the distribution start date to the 10th day, the second period from the 11th day to the 30th day from the distribution start date, and the 31st to 100th day from the distribution start date. The third period, from the 101st day to the 300th day, is the fourth period, and from the 301st day to the 900th day is the fifth period. And the frequency | count of singing in each period between 1st-5th is calculated from a singing log | history for every UID. For example, consumer M sings 0 times in the first period, 3 times in the 2nd period, 10 times in the 3rd period, 2 times in the 4th period, 5 times in the 5th period If so, a vector configuration having five values of 0, 3, 10, 2, and 5 is required for the consumer M. Such a vector configuration is calculated for each UID, subjected to SOM analysis, and classified into five groups. Then, in order from the group in which the peak position of the representative vector of each group is close to the distribution start date, a number with a lower timing ID is assigned.

  As described above, after creating a new UID_time ID table in S413, the control unit 610 transmits an update request for the UID_time ID table to the database server 500 (S414). The newly created UID_time ID table is also transmitted to the database server 500 together with the update request for the UID_time ID table.

  After performing S414, the control unit 610 performs S406 described above.

  Next, with reference to FIG. 24, the details of the time ID_advertisement ID table update process performed in S404 described above will be described.

  When the update process of the time D_advertisement ID table is started, the control unit 610 transmits a click log transmission request to the Web server 300 (S421).

  After transmitting the click log transmission request, it is determined whether a click history update completion notification is received from the Web server 300 (S422). If no click history update completion notification has been received, the process waits until a click history update completion notification is received (S422: No).

  When the click history update completion notification is received (S422: Yes), a transmission request for the click history, UID_time ID table, and advertisement ID_propagation date table is transmitted to the database server 500 (S423).

  After making a transmission request for the click history, UID_time ID table, and advertisement ID_propagation date table, it is determined whether or not the click history, UID_time ID table, and advertisement ID_propagation date table have been received (S424). When the click history, the UID_time ID table, and the advertisement ID_propagation date table are not received, the process waits until they are received (S424: No).

  When the click history, the UID_time ID table, and the advertisement ID_propagation date table are received (S424: Yes), the time ID_advertisement ID table is created based on the received data (S425). Details of the process of creating the time ID_advertisement ID table will be described later.

  Next, a request for updating the time ID_advertisement ID table is transmitted to the database server 500 (S426), and the process returns to S406 described above. In S426, the newly created time ID_advertisement ID table is transmitted together with the request to update the time ID_advertisement ID table.

  Next, with reference to FIG. 25, the details of the process of creating the time ID_advertisement ID table performed in S425 described above will be described.

  When the time ID_advertisement ID creation process is started, the control unit 610 determines an advertisement ID corresponding to the consumer M whose time ID is “1” (S431). Here, based on the advertisement ID_propagation date table received from the database server 500, the advertisement ID for the time ID “1” is determined. Control unit 610 extracts an advertisement ID that has passed the first propagation date from the advertisement IDs in the advertisement ID_propagation date table, and determines it as an advertisement ID corresponding to time ID “1”. For example, when the advertisement ID corresponding to the time ID “1” is determined on 2010/1/2 based on the advertisement ID_propagation date table shown in FIG. 11, the first propagation date in FIG. 11 is 2010/1/2. It is before. “0001”, “0002”, “0003”, and “0004” are determined as advertisement IDs corresponding to the time ID “1”. Note that, when there are a large number of advertisement IDs whose first propagation date has passed, the control unit 610 extracts a maximum of 20 advertisement IDs from the latest first propagation date.

  After determining the advertisement ID corresponding to the time ID “1” in S431, the control unit 610 creates a ranking of the number of clicks for each time ID (S432). For example, when creating a ranking based on the click history shown in FIG. 8, the control unit 610 operates as follows. The latest click log of the click history has a click date and time of “2010/4/1 4:01”, an advertisement ID of “0019”, and a UID of “000606”. Based on the click log, the control unit 610 first extracts the time ID corresponding to the UID “000606” based on the UID_time ID table acquired from the database server 500. Assuming that the time ID corresponding to “000606” is “1”, the control unit 610 next sets “0019_1c” which is a variable of the count value corresponding to the combination of the advertisement ID “0019” and the time ID “1”. "1" is added to the variable "." The number before “_” in this variable indicates “0019”, which is the corresponding advertisement ID. The number after “_” indicates “1” which is the corresponding time ID. The control unit 610 performs such processing for all click logs in the click history. Thus, a count value is calculated for each combination of all advertisement IDs and time IDs present in the click history. Next, a ranking arranged in descending order of count value for each time ID is created. For example, among the variables with the number “1” after “_”, the variable with the highest count value is arranged in order, and the consumer having the time ID “1” is referred to by referring to the portion indicating the advertisement ID of the variable. The ranking of the number of clicks corresponding to can be calculated. Here, respective rankings for the time IDs “1”, “2”, “3”, and “4” are created.

  In S432, after creating the ranking of the number of clicks, the control unit 610 determines the advertisement ID of the period ID2 (S433). Here, control unit 610 extracts four advertisement IDs that are higher in the ranking of time ID “1” and whose second propagation date has passed. Control unit 610 determines it as an advertisement ID corresponding to time ID “2”. Even if the ranking of the timing ID “1” is higher, the advertising ID for which the second propagation date has not passed is not adopted as the advertising ID of the timing ID “2”.

  Specifically, control unit 610 sequentially extracts the upper advertisement IDs in the ranking of time ID “1”, and acquires from database server 500 whether or not the second propagation date corresponding to the advertisement ID has passed. Judgment is made based on the advertisement ID_propagation date table. When the advertisement ID has passed the second propagation date, it is determined as the advertisement ID corresponding to the advertisement ID “2”, and when the second propagation date has not passed, the advertisement ID corresponding to the advertisement ID “2”. Not determined as. Control unit 610 repeats the above-described processing until four advertisement IDs are determined.

  After determining the advertisement ID corresponding to the time ID “2” in S433, the control unit 610 determines the advertisement ID corresponding to the time ID “3” (S434). Here, control unit 610 extracts three advertisement IDs that are higher in the ranking of time ID “2” and whose third propagation date has passed. Control unit 610 determines it as an advertisement ID corresponding to time ID “3”. Even if the ranking is higher in the ranking of the timing ID “2”, the advertising ID for which the third propagation date has not passed is not adopted as the advertising ID of the timing ID “3”.

  Specifically, control unit 610 sequentially extracts the upper advertisement IDs in the ranking of time ID “2”, and acquires from database server 500 whether or not the third propagation date corresponding to the advertisement ID has passed. Judgment is made based on the advertisement ID_propagation date table. When the advertisement ID has passed the third propagation date, it is determined as the advertisement ID corresponding to the advertisement ID “3”, and when the third propagation date has not passed, the advertisement ID corresponding to the advertisement ID “3”. Not determined as. Control unit 610 repeats the above-described processing until three advertisement IDs are determined.

  After determining the advertisement ID corresponding to the time ID “3” in S434, the control unit 610 determines the advertisement ID corresponding to the time ID “4” (S435). Here, control unit 610 extracts two advertisement IDs that are higher in the ranking of time ID “3” and have passed the fourth propagation date. Control unit 610 determines it as an advertisement ID corresponding to time ID “4”. Even if the ranking of the timing ID “3” is higher, the advertising ID for which the fourth propagation date has not passed is not adopted as the advertising ID of the timing ID “4”.

  Specifically, control unit 610 sequentially extracts the upper advertisement IDs in the ranking of time ID “3”, and acquires from database server 500 whether or not the fourth propagation date corresponding to the advertisement ID has passed. Judgment is made based on the advertisement ID_propagation date table. When the advertisement ID has passed the fourth propagation date, it is determined as the advertisement ID corresponding to the advertisement ID “4”, and when the advertisement ID has not passed the advertisement ID “4”, the advertisement ID corresponding to the advertisement ID “4”. Not determined as. Control unit 610 repeats the above processing until two advertisement IDs are determined.

  After determining the advertisement ID corresponding to the time ID “4” in S435, the control unit 610 determines the advertisement ID corresponding to the time ID “5” (S436). Here, control unit 610 extracts one advertisement ID that is higher in the ranking of time ID “4” and whose fifth propagation date has passed. Control unit 610 determines it as an advertisement ID corresponding to time ID “5”. Even if the ranking of the timing ID “4” is higher, the advertising ID for which the fifth propagation date has not passed is not adopted as the advertising ID of the timing ID “5”.

  Specifically, control unit 610 sequentially extracts the upper advertisement IDs in the ranking of time ID “4”, and acquires from database server 500 whether or not the fifth propagation date corresponding to the advertisement ID has passed. Judgment is made based on the advertisement ID_propagation date table. When the advertisement ID has passed the fifth propagation date, it is determined as the advertisement ID corresponding to the advertisement ID “5”, and when the advertisement ID has not passed the fifth propagation date, the advertisement ID corresponding to the advertisement ID “5”. Not determined as. Control unit 610 repeats the above processing until one advertisement ID is determined.

  After determining the advertisement ID corresponding to the time ID “5” in S436, the control unit 610 creates a new time ID_advertisement ID table based on the advertisement ID determined in S431, S433, S434, S435, and S436. (S437), the process returns to S426 described above.
