Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technology for introducing new content to a user using a viewing history of the user and an introducer from a large amount of content.
[0002]
[Prior art]
Currently, an enormous amount of content is provided in various media such as streaming content flowing on the Internet, television broadcasting, BS / CS digital broadcasting, and radio broadcasting.
[0003]
When searching for a huge amount of content, especially content that you want to watch from content on the Internet, users search for keywords from portal sites and search sites, or are interested in Web pages that are classified by genre. The method was to search for certain contents one by one. Also, some web pages provide a service that counts the number of accesses to each content and displays the content in a ranking in descending order of the number of accesses, and the user may select the content with reference to this. It was.
[0004]
Further, when searching for content provided by other media rather than on the Internet, the user has searched for content that he / she wants to view using a program guide or EPG (electronic program guide) on a paper medium.
[0005]
[Problems to be solved by the invention]
However, when displaying content by genre on the above portal site or web page, it takes time and effort to search for the desired content by changing the screen display many times, and there is an opportunity for the user to see content suitable for the user. There was a problem of being reduced.
[0006]
In addition, the service that displays the contents in the ranking in descending order of the number of accesses is a total of the accesses of all users, and does not reflect the user's individual preferences. Furthermore, even if there is content suitable for the user in the lower rank, there is a problem that the opportunity for the user to see it is extremely reduced compared to the upper content.
[0007]
The present invention has been made in view of the above problems, a content introduction method, a content introduction device, a content introduction program, and a program thereof that can introduce useful and useful content to the user with less burden on the user's operation. An object is to provide a medium on which is recorded.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a viewing history of a user (hereinafter referred to as a registered introducer) who has approved the viewing history of his / her content, and new content useful and useful for himself / herself. By comparing the viewing history of the content of the user you are looking for, extracting at least one registered introducer who has a hobby or preference for the content from the registered introducers and displaying the viewing history of the content to the user It is possible to introduce new contents useful and useful to the user.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 is a block diagram of a system configuration showing an example of an embodiment of the present invention. This system includes a plurality of registered introducer terminals 1, a user terminal 2, a content introduction device (hereinafter referred to as an introduction server) 3, and a network 4 that connects the registered introducer terminal 1, the user terminal 2, and the introduction server 3. Has been.
[0011]
The registered introducer terminal 1 has a viewing history DB 11 for accumulating content viewing history of the user (registered introducer) using the terminal up to the present time, and a viewing history for transmitting the accumulated content viewing history to the introduction server 3. And a transmission unit 12.
[0012]
The user terminal 2 includes a viewing history DB 21 that accumulates the viewing history of the content of the user who uses the terminal, a viewing history transmission unit 22 that transmits the accumulated viewing history of the content to the introduction server 3, and an introduction server. 3, a display unit 23 that displays the content information introduced from 3 and the registered introducer, an instruction input unit 24 that inputs an instruction to select (start viewing) or stop viewing the content, and a user instruction received by the instruction input unit 24 Is transmitted to the introduction server 3.
[0013]
The introduction server 3 includes a viewing history receiving unit 31, 32, a viewing history analyzing unit 33, a registered introducer DB 34, a user viewing history DB 35, a viewing history comparison extracting unit 36, a result transmitting unit 37, and a viewing presence / absence examination. Part 38.
[0014]
The viewing history receiving unit 31 receives the viewing history of the registered introducer's content from the registered introducer terminal 1. The viewing history receiving unit 32 receives the viewing history of the user content from the user terminal 2.
[0015]
The viewing history analysis unit 33 analyzes the viewing history stored in the registered introducer DB 34 from the received viewing history of the registered introducer, and analyzes the viewing history stored in the user viewing history DB 35 from the received viewing history of the user.
[0016]
The registered introducer DB 34 stores the viewing history of the registered introducer analyzed by the viewing history analysis unit 33, and accumulates the number of times the registered introducer introduced to the user by the introduction server and the number of times the content information has been accessed by the user. The user viewing history DB 35 stores the user viewing history analyzed by the viewing history analysis unit 33.
[0017]
The viewing history comparison / extraction unit 36 compares the viewing history of the registered introducer with the viewing history of the user, and extracts the content information to be transmitted to the user and the registered introducer from the registered introducer DB 34. The result transmission unit 37 transmits the content information extracted by the viewing history comparison extraction unit 36 and the registered introducer to the user terminal 2.
[0018]
The viewing presence / absence examining unit 38 examines whether the user has viewed the content from the content information transmitted to the user terminal 2 by the result transmitting unit 37 and describes the result in the registered introducer DB.
[0019]
FIG. 2 is a flowchart for explaining the operation of the viewing history comparison and extraction unit 36. Hereinafter, the operation among the registered introducer terminal 1, the user terminal 2, and the introduction server 3 will be described using this.
[0020]
The registered introducer terminal 1 of the registered introducer who has registered in the introduction server 3 that the viewing history of his / her content may be disclosed is displayed as the viewing history of the content including the content information viewed by himself / herself as shown in FIG. When stored in the viewing history DB 11 and the registered introducer connects the registered introducer terminal 1 to the network 4, at regular intervals (every day, every day, every hour, every few minutes, every time content is viewed). The accumulated viewing history is transmitted to the introduction server 3 via the viewing history transmission unit 12.
[0021]
“Unviewed” in FIG. 3 means that the content has been accessed, but the content has not been viewed (reproduced) until the end. Therefore, if the user presses the “stop” button during playback of the content, the content is defined as “unviewed”. In addition, the viewing history of the content transmitted to the introduction server is only viewed after the viewing history transmitted to the introduction server last time, and duplication is avoided.
[0022]
The introduction server 3 receives the viewing history of the content transmitted from the registered introducer terminal 1 by the viewing history receiving unit 31 and stores it in the registered introducer DB 34. At this time, the viewing history analyzing unit 33 does not check the viewing history from the viewing history. The viewing content is excluded, and the number of times the same content has been viewed is added and stored (stored) (step 101). FIG. 4 shows an example of viewing history / number of times data stored in the registered introducer DB 34.
[0023]
On the other hand, the user terminal 2 of the user who uses the introduction server 3 accumulates the viewing history of the content including the content information viewed by himself / herself in the viewing history DB 21 as shown in FIG. 3, the stored viewing history is transmitted via the viewing history transmitting unit 22. At this time, the viewing history of the content transmitted to the introduction server is only viewed after the viewing history transmitted to the introduction server last time, as described above, to avoid duplication.
[0024]
The introduction server 3 receives the viewing history of the content transmitted from the user terminal 2 by the viewing history receiving unit 32 and stores it in the user viewing history DB 35. At this time, the viewing history analysis unit 33 uses the viewing history from the viewing history as described above. Unviewed content is excluded, and the number of times the same content has been viewed is added and stored (stored) (step 102). FIG. 6 shows an example of viewing history / number of times data stored in the user viewing history DB 35.
[0025]
The viewing history comparison / extraction unit 36 of the introduction server 3 compares the viewing histories of all registered introducer's contents stored as described above with the viewing history of the user's contents, and the registered introducer having a high probability of matching. And the content information are extracted as described later (step 103), and further sorted according to the criteria described later are transmitted to the user terminal 2 via the result transmitting unit 37. The user terminal 2 displays the result on the display unit 23. (Step 104).
[0026]
Hereinafter, the process of extraction and sorting will be described by taking as an example the case where the content of the registered introducer DB is FIG. 4 and the content of the user viewing history DB is FIG.
[0027]
A registered introducer having content information matching (common) with the user's viewing history is extracted. At this time, registered introducer A has the same content (1) and content (3), registered introducer B has the same content (1) and content (3), and registered introducer C has the same content (3). To do.
[0028]
The first sort criterion is the order of registered introducers who have more content information in common with the user's viewing history. Registered introducer A has two contents in common, registered introducer B has two contents information in common, and registered introducer C has one content in common (registered introducer A or registered introducer B). It becomes the order of registered introducer C.
[0029]
Next, since the registered introducer A and the registered introducer B have the same number of pieces of content information in common with the user's viewing history, sorting is performed using the second sort criterion.
[0030]
Here, the second sorting criterion is “total hit rate”. This “total hit rate” is the number of times that all content introduced from the referral server has been played to the end (total number of viewers). (Number of times) and calculated for each registered introducer.
[0031]
The higher the “total hit rate”, the more the content information introduced by the registered introducer to the user has been viewed. Therefore, it can be determined that the introduced registered introducer and the content information are more useful to the user. Therefore, “total hit rate” is used as the second sorting criterion. As a result, the total hit rate of registered introducer A is 20%, and the total hit rate of registered introducer B is 57%. Therefore, the order of registered introducers introduced to user A is registered introducer B and registered introducer. Person A and registered introducer C.
[0032]
When the “total hit rate” is also the same value, the sorting is performed in the order of registered introducers who are viewing the same content information more frequently than the content information that the user has viewed many times. If the same is still true, the order is in accordance with an arbitrary rule unrelated to content viewing, such as the order of registration of registered introducers on the registered introducer DB.
[0033]
Next, the content information introduced among the registered introducers selected by the above method is sorted. In the case of the registered introducer B, the contents (1) and (3) are already viewed by the user A, so the contents (4) and (6) are introduced to the user A. At this time, sorting is performed in descending order of the “hit rate” for each piece of content information.
[0034]
This “hit rate” is the number of times the content introduced from the referral server has been played to the end (viewed number) divided by the number of times the content has been played but not played to the end (number of times introduced) This value is calculated for each registered introducer in content units.
[0035]
It can be determined that the introduced content information is more useful for the user because the higher the “hit rate” is, the more the content information introduced to the user is viewed. However, here, since the hit rates of the contents (4) and (6) of the registered introducer B are both “77%”, the content information is sorted next in descending order of the number of times the registered introducer has viewed. Since the registered introducer B views the content (4) four times and the content (6) twice, the sorting order is the order of the content (4) and the content (6). If the same is still true, the order is in accordance with an arbitrary rule unrelated to content viewing, such as the order of content registration on the registered introducer DB.
[0036]
As described above, as a result of comparing the viewing history of user A with the viewing history of registered introducer, the registered introducer and content information transmitted and displayed to user A's user terminal are as shown in FIG. become.
[0037]
Therefore, the user can acquire useful and useful new content information from the introduction server.
[0038]
Next, the introduction server 3 verifies whether or not the user has actually viewed using the introduced content information (step 105). FIG. 8 is a flowchart for explaining the operation of the viewing presence / absence examining unit 38, which will be described below.
[0039]
First, the viewing presence / absence examining unit 38 of the introduction server 3 determines whether the user has actually accessed and viewed the content from the introduced content information (step 201). This determination is made based on whether or not information (first information) transmitted from the instruction transmission unit 25 is received when the user clicks on the content information displayed on the introduced page by operating the instruction input unit 24. (Note that the content itself is provided from a content holding site on a network (not shown)). If the user has not accessed any content using the introduced content information, the process ends.
[0040]
If the user actually accesses the content using the introduced content information, the “introduced number” of the corresponding content information of the registered introducer who introduced the selected content information is incremented by 1 (step 202).
[0041]
Next, the viewing presence / absence examining unit 38 of the introduction server 3 determines whether or not the content selected by the user has been viewed to the end (step 203). This determination is based on whether or not the information (second information) transmitted from the instruction transmission unit 25 is received when the user operates the instruction input unit 24 during the content reproduction to perform the “stop” operation. Do. If the user accesses other content before the information indicating that the user has performed the “stop” operation is transmitted to the introduction server, it is considered that the content currently being viewed has been played to the end. . Thereby, the introduction server determines whether the content has been viewed to the end.
[0042]
If the content has been viewed to the end, the “viewed number” of the corresponding content information in the corresponding registered introducer column of the registered introducer DB 34 is incremented by 1 (step 204). For example, if the user A has watched the content (4) of the registered introducer B to the end, the introduction server 3 will display “number of times viewed” of “content (4)” of “registered introducer B” in the registered introducer DB 34. And increase the number of referrals by one.
[0043]
Next, the “number of times of viewing” is divided by the “number of times of introduction”, and the “hit rate” for each piece of content information is calculated and added to the registered introducer DB 34 (step 205). Also, for each registered introducer, the “viewed number” and the “referred number” are totaled, the “total viewed number” and the “total introduced number” are calculated, and the “total viewed number” is Divide by the “number of referrals” to calculate the “total hit rate” (step 206).
[0044]
As described above, new content information can be provided to the user using the viewing history of the user and the registered introducer.
[0045]
In the above-described embodiment, a reward (guarantee) may be paid to the registered introducer using the “hit rate” or “total hit rate”.
[0046]
In other words, publishing the viewing history of one's own content triggers other users to view new content. For example, the registered introducer's “hit rate” and “total hit rate” exceed a certain line. At this time, a guarantee may be paid from the content holding site (content owner) to the user. Here, the fixed line is a line uniquely determined by the content holding site and is not fixed (for example, the hit rate of the content (1) is 50% or more). Guarantee includes reduction of cash and line usage fees, coupon tickets, and free viewing rights for paid content.
[0047]
【The invention's effect】
As described above, according to the present invention, it is possible to introduce content that is more useful and useful to the user from a vast amount of content without special operations by the registered introducer or user.
