<Data structure>
The system according to the present embodiment has a function of associating a plurality of contents and presenting the contents to the user according to the association. In the present embodiment, content is handled as an element that constitutes a single article composed of a plurality of contents. The content may be content automatically collected from outside the system, or content posted to the system by the user. The system according to the present embodiment can handle various types of content such as articles, photos, videos, and combinations thereof as content.

  FIG. 3 is a diagram illustrating a state in which contents are associated with each other in the present embodiment. In the present embodiment, the content is associated with other related content, and the association information indicating the connection (association) between the contents is held in the database 3. A connection between contents may be created by content analysis, or may be created when another content is designated (recommended) as a related content by a user. The server generates association information indicating the connection (association) between the contents targeted for association, and stores the association information in the database 3 to create a connection between the contents. The designation of the related content by the user may be performed when the content is created by the user (for example, “ADD” operation of the content by the user), or may be performed at an arbitrary timing after the content is created. In the present embodiment, when new content is created in a state where a certain content is specified, or when other existing content is additionally specified in a state where a certain content is specified, the contents are directly associated (described later). Will be in a “primary connection” state). In addition, designation of related content for a certain content can be performed not only by the user who created the content but also by other users.

  Further, the association between contents can be canceled by a user operation. In this embodiment, when the associated content is specified, the user performs an “OMIT” operation on the content, thereby deleting the association information indicating that the content is directly associated with each other, and releasing the association. Is done.

In the present embodiment, primary, secondary, and tertiary connections between contents are defined for each content. Here, the “n-th order connection” means that the minimum number of hops for tracing and reaching a related content from a certain content is n, in other words, a certain content and related content are (n -1) It shows that it is connected through other contents. That is, “primary connection” indicates the relationship when the contents are directly connected to each other (the number of hops is 1), and “secondary connection” indicates that the contents are indirectly connected to each other via one other content. Indicates the relationship when hops are connected (hop number 2), and “tertiary connection” indicates the relationship when the contents are indirectly connected via the other two contents (hop number 3). Show.

  In the present embodiment, the user can create a content group that is a set of arbitrary content. A content group is a set of contents including a plurality of contents grouped by a user as a group of contents related to each other. A method in which a user creates a predetermined content group and then drags and drops the content into the content group area, or a method in which a plurality of contents are specified and a determination operation is performed as belonging to a single content group Etc. can be used to create a content group including a plurality of contents related to each other. Note that it is also possible to exclude content from a once created content group or eliminate the content group based on a user operation.

<Recommendation level analysis processing>
Hereinafter, in the present embodiment, a recommendation level analysis process for analyzing the magnitude (recommendation level) of the degree of association between a certain content and other content will be described. The recommendation level analysis process may be periodically executed as a batch process by the analysis server 2 or may be executed each time a recommended content acquisition process described later.

  Here, the analysis server 2 calculates a distance between contents having 1 to n-th order (up to third order in the present embodiment), and recommends related contents closer to a certain content with a recommended degree. Use highly recommended content. In this embodiment, content analysis is performed using a multidimensional scaling method (MDS: Multi Dimensional Scaling), and related content is recommended to the user using this result. Hereinafter, a method of calculating the distance for each content will be described more specifically.

  First, the analysis server 2 checks whether or not there is a connection for each primary, secondary, and tertiary connection order between contents. When there is at least one n-th order connection between two contents (for example, contents A and B), p (n, A, B) = 1 is set, and none exists , P (n, A, B) = 0. In the present embodiment, fourth-order or higher-order connections are ignored by setting p (n, A, B) = 0. It may be determined appropriately for each form.

  Next, presence determination of the content group is performed. The analysis server 2 confirms the presence or absence of a common content group among the contents. In the present embodiment, when both the contents A and B belong to the same content group α, δ (α, A, B) = 1 is set, and when they do not belong to the content group α, δ (α, A, B) = 0 is set.

  Thereafter, the analysis server 2 calculates the distance between the contents A and B that are superimposed and added over all the content groups using the content group weight of the content group α as k (α), using the following formula 1. . Here, the content group weight k (α) is a value obtained by evaluating the importance for each content group from the viewpoint of the content group creation user, information accuracy, and the like.

・・・（式１）

... (Formula 1)

  Furthermore, the analysis server 2 combines the calculated “distance between contents based on content group” and “inter-content distance based on connection between contents”, thereby “inter-content distance used for determining recommended content”. Is calculated. Here, the “inter-content distance based on the content group” is weighted by an “order distance weight s (n)” that is applied to each order of connection. Further, the “distance between contents based on the connection between contents” is weighted by the “content group distance weight t” applied to each content group (see the following Expression 2). That is, the content distance dist (A, B) between the content A and B is calculated using the following equation 2.

・・・（式２）

... (Formula 2)

It should be noted that “order distance weight s (n)” and “content group distance weight t” are preferably set to appropriate values for each embodiment. For example, in this embodiment, “order distance weight s (n)” and “content group distance weight t” are set as follows.
s (1) = 1
s (2) = 0.5
s (3) = 0.33
t = 0.5

  By calculating the distance for each content with respect to the content by the above-described processing and making the related content closer to the distance a related content with a higher recommendation level, it is possible to obtain a recommended content with a high degree of relevance for a certain content I can do it. However, the distance between contents may be calculated using other methods, and the recommended contents may be determined according to other criteria. Note that the recommended content obtained for each content is held in the database 3.

<Process flow>
Next, details of processing according to the present embodiment will be described. Note that the specific contents and order of the processing described in the present embodiment are examples for carrying out the present invention. Specific processing contents, order, and the like may be appropriately selected for each embodiment.

  FIG. 4 is a flowchart showing the flow of recommended content acquisition processing using the analysis result described above according to the present embodiment. The processing shown in this flowchart is started when an application having a recommended content acquisition function is started.

  5 to 9 are diagrams showing an outline of a screen displayed on the display device 36 at each stage of the recommended content acquisition process according to the present embodiment.

First, content cards are displayed side by side on the display device 36 (see FIG. 5). The card displayed here is a content card belonging to one of the preset content groups.

  In step S101 and step S102, selected content that is a key for content recommendation is determined, and an area in which the recommended content is displayed is determined. The selection determination unit of the client terminal accepts a selection operation (see FIG. 5) by the user, and selected content that is a key for content recommendation selected by the user from among the plurality of contents displayed on the display device 36. Is determined (step S101). Here, the selection operation is, for example, tap or tap and hold (long press) to an area where a card is displayed on the display device 36 provided with a touch panel, click or drag using a pointing device such as a mouse, or the like. It is. That is, the user performs an operation of selecting a card of content of interest (card A in the figure) on an interface device having a pointing device such as a touch panel or a mouse, thereby selecting a selected content that is a key for content recommendation. Can be specified.

  Then, the area determination unit of the client terminal receives an area selection operation (see FIG. 6) by the user, and determines an area where the recommended content is displayed by the display device 36 according to the area selection operation (step S102). Here, the area selection operation is, for example, any one of squares displayed in advance in an interface device including a pinch-out (operation to expand an area with two fingers) on a touch panel or a pointing device such as a mouse. For example, an operation of holding the apex and moving it toward the outside of the square. That is, the user can select an area in which a content card related to the content of interest is displayed in an interface device including a pointing device such as a touch panel or a mouse. Thereafter, the process proceeds to step S103.

  In step S103 and step S104, the number of recommended contents is determined, and related contents up to the determined number are recommended. The recommended number determination unit calculates the number of cards that can be included in the area based on the area determined by the area determination unit, and uses the calculated number of cards as the number of contents recommended by the recommendation unit. Determine (step S103). Then, the recommendation unit refers to the result of the recommendation level analysis process, and recommends the content in descending order of the recommendation level from the content associated with the selected content up to the number determined in step S103 (step S104). ). The method for obtaining related content having a higher recommendation level for a certain content is as described in the description of the recommendation level analysis process. Thereafter, the process proceeds to step S105.

  In step S105, the order of recommended content recommended by the recommendation unit is determined. The rank determination unit determines the rank of the recommended content by arranging the recommended content in descending order of recommendation. More specifically, the order determination unit arranges the recommended content recommended by the recommendation unit in the order of the smaller number of other contents through the association, that is, the order of the “n-order connection” order, and recommends the same order. For the content, the order of the recommended content is determined by arranging in order of the recommendation level. Thereafter, the process proceeds to step S106.

  In step S106, some of the cards in the selected area (hereinafter “selected area”) are moved out of the selected area. When the selection area for displaying the recommended content is determined, the display control unit of the client terminal 9 excludes the card (in the figure) excluding the selected content card determined in step S101 from the cards included in this area. In the example shown, the cards B, G and H) are moved out of the selection area so as to be pushed out of this selection area (see FIG. 7). Thereafter, the process proceeds to step S107.

In step S107 and step S108, recommended content is displayed in the selected area, and cards outside the selected area are aligned. The display control unit moves the recommended content cards (in the example shown in the figure, cards D, E, H, X, and Y) to the inside of the selection area, and from the selected content in the order determined by the rank determination unit. It is displayed around the selected content so that the distance is short (see step S107, FIG. 8). Specifically, the arrangement order of the cards moved to the inside of the selection area is a card of contents having a primary, secondary, and tertiary connection in order from the card A. Further, among the primary, secondary, and tertiary connections, the content card having a shorter distance calculated by the recommendation level analysis process moves closer to the card A. In the example illustrated in FIG. 3, the primary connected content with respect to the content A is the content D, E, and H, the secondary connected content is the content X, the tertiary connected content is the content Y, and further the primary Since the contents D, E, and H are in descending order of distance from the content A in the connection, the cards are arranged as shown in FIG. Note that the display control unit may display the recommended content card such that the higher the recommendation level, the larger the card, according to the content recommendation level. In this way, it is possible to provide the user with more highly recommended content that is easier to see.

  Then, the display control unit displays the cards outside the selection area, that is, cards other than the recommended content in an aligned manner (see step S108, FIG. 9). Thereafter, the processing according to this flowchart ends.

  In the present embodiment, the user can cancel the association between the contents by performing an “OMIT” operation for removing the unnecessary contents with respect to the content acquisition result by the recommended content acquisition process. For example, in the example illustrated in FIG. 9, the contents D, E, H, X, and Y are acquired as the recommended contents related to the content A. However, the user thinks that the content Y is not related to the content A. In this case, by selecting the content Y card and performing an “OMIT” operation (specific operation is, for example, pressing the “OMIT” button, etc., illustration is omitted), the content A and the content Y are The association can be canceled and the content Y card can be deleted from the selected area.

  In the portion that has become blank due to the deletion of the content Y card, the related content card (for example, content Z) with the next highest recommendation level is displayed according to the ranking of the recommended content determined by the ranking determination unit. The By doing in this way, the user can repeat the acquisition of the recommended content and the release of the association, and create an edited material composed of the desired content.

  Note that the content that can be selected by the user for the recommended content acquisition process is not limited to the content of the card displayed at a specific position. For example, after the acquisition of the recommended content with the content A as the selected content according to the above-described example is completed, the user can acquire the recommended content with another content as the new selected content (FIG. 10). See).

  FIG. 10 is a diagram showing an overview of a display screen for an area selection operation in the recommended content acquisition process according to the present embodiment. According to the example shown in FIG. 10, after the recommended content is acquired with the content A as the selected content, the association of the content Y is canceled and the content Z is supplemented accordingly, and the content B is recommended as the new selected content. It can be seen that the content can be acquired. Since the process for acquiring the recommended content for the content B is the same as the above-described recommended content acquisition process, the description thereof is omitted. By repeating such recommended content acquisition processing, the user can fill the screen with content that the user is interested in with only a simple operation.

According to the information processing system according to the present embodiment, the processing as described above is executed, so that the user only performs an intuitive operation to view the card of the content of interest more closely. Content related to certain content can be obtained.
