In addition, when participation is permitted, information such as introduction of friends who have already participated in the social network is registered. The management server 3 configures a social network based on the friend information.

<Structure of social network>
Here, the configuration of the social network will be described. FIG. 2 is a diagram illustrating a configuration example of the social network in the present embodiment. The social network shown in FIG. 2 shows an example of a human relationship (friend network configuration) in a social network service centered on a user who uses the above-described recommendation order selection device 2 as an example.

  That is, by requesting the current network configuration from the management server 3, a human relationship network set based on a friend who can connect to the social network and the user is acquired.

  Specifically, as shown in FIG. 2, the user has three direct “friends” A, B, and C, and two “friends of friends” D and E through the friend A. Furthermore, there are two “friends of friends of friends” named J and K via D, and three “friends of friends of friends of friends” named X1, X2 and X3 via J. Exists.

  Thus, if attention is paid only to the “distance” of the human relationship, as shown in FIG. 2, the user has three direct “friends” A to C, and “friends of friends” are D to I. There are 13 "friends of friends of friends" from J to V, and there are 35 "friends of friends of friends of friends" from X1 to X35.

  That is, the priority order in the social network relationship is set based on the relationship with the user (user), the information of each content is weighted according to the criterion, and the order of the recommendation information is selected. In addition, the social network as shown in FIG. 2 is constantly updated at a predetermined time, for example, at a predetermined timing such as participation / non-participation of a certain person in the social network, and in the management server 3 that manages the social network, etc. It is assumed that it is centrally managed.

  The user can acquire information on the social network by accessing the management server 3 described above through the network interface unit 30 of the recommendation order selection device 2.

  Next, the functional configuration of the recommendation order selection device 2 in the present embodiment will be specifically described with reference to the drawings. In the following description, the description is limited to the case where a program is handled as an example of content recommended to the user. However, the content in the present invention is not limited to this, and other than the program, there are various types of music, products, games, and the like. It may be the content.

<Importance calculation acquisition management unit 10>
First, the functional configuration of the importance calculation information acquisition management unit 10 will be described with reference to the drawings. FIG. 3 is a diagram illustrating an example of a functional configuration of the importance calculation information acquisition management unit. The importance calculation information acquisition management unit 10 shown in FIG. 3 is configured to include a user interface unit 101, an operation content acquisition unit 102, an active evaluation acquisition unit 103, and an importance calculation information management unit 104. Yes.

  The user interface unit 101 receives a recording reservation operation from a user, an operation during viewing, active evaluation information regarding a program to be viewed (or viewed), and the like. In addition, the user interface unit 101 outputs information input from the user to the operation content acquisition unit 102 and the active evaluation acquisition unit 103.

  The operation content acquisition unit 102 acquires information on the operation content for recording reservation or viewing by the user from the information obtained from the user interface unit 101, and outputs the information to the importance calculation information management unit 104. In addition, the active evaluation acquisition unit 103 acquires the active evaluation content performed by the user on the program via the user interface unit 101, and outputs the content to the importance calculation information management unit 104.

  Here, the active evaluation is, for example, before the broadcast of the program (or before the viewing), such as “recommend personally because this performer and this director must be absolutely interesting”. If it is a lot of information, or after the broadcast, “I personally recommend it because I watched it was very interesting,” or “I highly recommended it because it was the best program I watched.” “It was a very boring program that I watched, so I gave a low rating.” Note that the user's input of the evaluation for the program is not necessarily a necessary operation, but can be performed when each user wants to actively recommend to other friend users. Note that the above-described evaluation contents may be directly input, or a selection screen for selecting any of the above-described contents set in advance may be displayed to allow the user to select.

  The importance calculation information management unit 104 manages the operation information received from the operation content acquisition unit 102 and the active evaluation operation information received from the active evaluation acquisition unit 103. Here, an example of information managed by the importance degree calculation information management unit 104 will be described with reference to the drawings. FIG. 4 is a diagram illustrating an example of importance calculation information.

  As shown in FIG. 4, for example, information about programs A, B, and C is managed as information obtained from the operation content acquisition unit 102 such as when recording is actively reserved or when a program is viewed. In addition, as information obtained from the active evaluation acquisition unit 103, when personally recommending before program broadcast (or before viewing), when personally recommending after viewing, when personally recommending after viewing, Manage information such as personally disliked after viewing.

  The information managed by the importance degree calculation information management unit 104 is not limited to this, and the form of the managed information is also managed for each program, but the present invention is not limited to this. For example, during viewing of a program, since the program is boring midway, such information may be managed when viewing of the program is stopped or when the program is recorded and repeatedly viewed.

  Also, the information as shown in FIG. 4 is necessary when the recommendation rank selection unit 20 in the other recommendation rank selection device 2 wants to acquire importance calculation information for the user. That is, when there is a request for information acquisition from another recommendation order selection device 2, the importance calculation information management unit 104 transmits information from the network interface unit 30 via the communication network 4.

<Recommendation order selection unit 20>
Next, the functional configuration of the recommendation order selection unit 20 will be described with reference to the drawings. FIG. 5 is a diagram illustrating an example of a functional configuration of the recommendation order selection unit. The recommendation order selection unit 20 shown in FIG. 5 includes a friend network configuration information acquisition unit 201, a use friend selection unit 202, a setting status management unit 203, a weighting processing unit 204, an importance calculation information acquisition unit 205, And a recommendation rank calculation unit 206.

  The friend network configuration information acquisition unit 201 communicates with the management server 3 or the like that manages the entire social network service via the communication network 4 from the network interface unit 30, and the friend network configuration (social network in the user's social network service) Get information on relationships within the service. In addition, the friend network configuration information acquisition unit 201 outputs the acquired network configuration information to the use friend selection unit 202.

  The friend selection unit 202 sets which friend (predetermined person) information in the friend network is to be used in calculating the recommendation order. At this time, the use friend selection unit 202 sets the setting based on both the setting content preset by the user from the setting status management unit 203 and the content of the friend network configuration information obtained from the friend network configuration information acquisition unit 201. It can be carried out.

  For example, in the use friend selection unit 202, the setting content received from the setting status management unit 203 is up to “friends of friends of friends”, and the friend network configuration information received from the friend network configuration information acquisition unit 201 is described above. In the social network configuration shown in FIG. 2, only the friends (“friends”, “friends of friends”, and “friends of friends of friends”) necessary for calculating the recommendation rank are extracted from the network configuration of friends shown in FIG. The friend network configuration is as shown in FIG.

  In the example of the friend network configuration to be used shown in FIG. 6, a total of 22 people A to V are selected as “friends of the user's friends”. Therefore, the recommendation order of programs is selected based on information obtained from this friend.

  Note that the method of selecting a friend to be used is not limited to this. For example, only the friends A, D, K, and J in FIG. 6 may be selected. Only K and J may be selected. In addition, a group may be set in advance in a predetermined network range, and whether or not to use the group unit may be set.

  The use friend selection unit 202 outputs information on the selected friend to the importance calculation information acquisition unit 205.

  The weighting processing unit 204 performs weighting processing on each friend used for calculation of the recommendation order obtained from the setting status management unit 203 according to the distance between the user and each friend on the friend network. . Here, an example of weighting in the weighting processing unit 204 will be described with reference to the drawings.

  FIG. 7 is a diagram illustrating an example of setting a weighting value. In the example shown in FIGS. 7A to 7D, at least a network distance from the person (user), a relationship with the user, and a weighting value for the relationship with the user are set.

  Specifically, FIG. 7A shows an example in which weighting is set with emphasis on the user's direct friend. In other words, since the direct “friend” is important for the user, the “friend” has a weight of “5”, the “friend of the friend” is “2”, and the “friend of the friend of the friend” is “1”. The weighting is set lower as the distance from is increased. FIG. 7B shows an example in which the weighting value is set in proportion to “5” → “3” → “1” based on the distance from the user on the network. FIG. 7C shows an example in which a constant weight value is set regardless of the distance from the user. It should be noted that by making settings as shown in FIG. 7C, it is possible to search for programs that are generally popular and popular.

  Further, FIG. 7D shows a case where “B” is the best friend of the user among friends (A, B, C), a case where “B” is met in the near future, or other recommended information. When “B” is the most detailed among the friends in a certain field when obtaining the “B”, the weight of the friend B among the friends can be set particularly large. Similarly, the friend of the friend (D, E, F, G, H, I), for example, the friend of the friend (D, G, H) is weighted more than the friend of the friend (E, F, I). It can be set to increase.

  The user can acquire other recommendation information under various conditions by performing weighting as shown in FIGS. 7A to 7D in the weighting processing unit 204.

  Note that the weighting setting method is not limited to the content shown in FIG. The policy to be weighted is set based on the setting contents received in advance by the user from the setting state management unit 203. Further, the weighting processing unit 204 outputs the set weighting information to the recommendation order calculating unit 206.

  As described above, the setting status management unit 203 manages the setting contents preset by the user, such as the range of friends used for calculating the recommendation order and what policy is used for weighting. 202, information necessary for the weighting processing unit 204 and a recommendation rank calculation unit 206 described later is output.

  Also, the importance calculation information acquisition unit 205 receives information on which friend to use for calculating the recommendation order from the use friend determination unit 202, and the network interface unit 30 transmits the information via the communication network 4 according to this information. All of them communicate with the recommendation order selection device 2 of friends to acquire importance calculation information. When the management server 3 and other servers described above manage the importance calculation information of the recommendation order selection devices 2-1 to 2-n in a unified manner, the importance calculation is performed from these servers. Get information. The importance calculation information acquisition unit 205 outputs the acquired importance calculation information to the recommendation rank calculation unit 206.

  Here, the information that the importance calculation information acquisition unit 205 receives from the user's friend system and outputs to the recommendation ranking calculation unit 206 is the information shown in FIG. 4 described above. That is, information on general operations such as “recording reservation” operation and “program viewing” operation performed on each program by the user's friend, and active evaluation performed on the program by the user's friend. This is information on the attaching operation. The recommendation rank calculation unit 206 determines the importance of each program obtained for each friend set in the use friend selection unit 202 based on the importance setting criteria.

  It should be noted that the recommendation level calculation unit 206 sets the importance level for determining the importance level with reference to the setting content in the setting status management unit 203. Here, an example of the importance setting criterion will be described with reference to the drawings.

  FIG. 8 is a diagram illustrating an example of importance setting criteria. Note that the setting content of the importance setting criteria shown in FIG. 8 includes an operation time, an operation content of each user, and an importance level corresponding to the operation content. Here, FIG. 8 (a) shows an example of setting importance that emphasizes each person's active evaluation, and FIG. 8 (b) shows an example of setting importance that emphasizes each person's viewing trend. That is, it shows an example of setting the importance with an emphasis on whether or not each friend has watched the program. As shown in FIG. 8, the importance addition value and subtraction value are set based on the operation of each user (“0” when addition and subtraction are not performed).

  The recommendation information rank calculation unit 206 determines the importance value of each program for each friend set as described above from the operation information for each program by the user's friend received from the importance calculation information acquisition unit 205. Then, the recommendation rank is calculated from the weight value of each friend received from the weighting processing unit 204. Here, an example of recommendation rank calculation in the recommendation information rank calculation unit 206 will be described with reference to the drawings.

  FIG. 9 is a diagram illustrating an example of the relationship between the weighting value and importance of each friend. Although FIG. 9 shows an example in which the recommendation order is selected for five programs from program 1 to program 5, the number of programs and the content content are not limited to this in this embodiment.

  FIG. 9 shows the weighting of each friend received by the recommendation rank calculation unit 206 from the weighting processing unit 204 in each friend (persons A to V) corresponding to the network configuration shown in FIG. The importance of the program set from the value and the operation content of each friend is shown.

  In addition, the weighting value of each friend shown in FIG. 9 shows an example in which the weighting value shown in FIG. The importance of each program shown in FIG. 9 is determined based on the operation information for each program by each friend for five programs from program 1 to program 5 as shown in FIG. The importance value of each program for each friend set based on is shown.

  Here, in the case of FIG. 8A, for example, for the program 1 of person A, the recording reservation operation is actively performed (+1), and the program is actually viewed (+1), but the active evaluation operation is performed. If there is no (0), the importance value is calculated as “1 + 1 + 0 = 2”. In this way, the importance of each program of each friend is set.

  In the case of the example of FIG. 9, since person A is a direct friend to the user, the weight value is “5”, the importance value of program 1 for person A is “2”, and the importance value of program 2 Is “5”, the importance value of program 3 is “1”, the importance value of program 4 is “3”, and the importance value of program 5 is “5”.

  Next, the recommendation rank calculation unit 206 multiplies the weighting value based on the distance to the friend with respect to the above-mentioned friend by the importance of each program (weighting value × importance of each program), and calculates each program from the calculated value. Calculate the total for each.

  Here, FIG. 10 is a diagram illustrating an example of the calculation result of the importance level of the user based on FIG. In FIG. 10, it can be determined that a result having a large total value has a high evaluation among the user's friends or is viewed by many of the user's friends. Therefore, the recommendation rank calculation unit 206 sorts the programs based on the total value, and selects the recommendation rank in descending order of the total value. In the case of the example in FIG. 10, the recommendation order of the five programs is, in descending order of the total value, program 2 (178) → program 5 (169) → program 4 (128) → program 1 (97) → program 3 (82). Become.

  Using the recommendation order obtained as described above, for example, before broadcasting (or before viewing), a recording device or the like that automatically reserves a recording for a program that has a high recommendation order and is not reserved for recording. Control information can be output. In addition, after the broadcast, it is possible to recommend a program that has been recorded but has not been viewed by presenting it to the user according to the recommendation order. In addition, the recommendation rank calculation part 206 is the information of the content of the priority set beforehand, such as a program from the 1st rank to the 3rd rank, or only a 5th rank program among the ranked programs. It may be output. Thereby, only the content information required by the user can be efficiently presented to the user.

  As described above, the recommendation order selection device 2 can select the recommendation order of content with high accuracy based on the relationship between the user and the other party.
