First, an example of information processing according to the embodiment will be described using FIG. 1. FIG. 1 is a diagram illustrating an example of information processing according to an embodiment.

The information processing device 1 shown in FIG. 1 is an information processing device that cooperates with the terminal device 2 of each user U and provides various information to each user U online, for example, by using one or more servers or a cloud system. Realized.

The information processing device 1 provides various contents. User U can, for example, use news, weather, rain clouds, disasters, e-mails, routes, payments, shopping, auctions, tickets, finance, sports, events, videos, music, TV programs, travel, restaurants, traffic jams, congestion, and routes. , maps, route searches, web searches, cooking, and other content can be acquired from the information processing device 1 . In the following, a case where the content mainly provided by the information processing device 1 is news content will be described as an example.

As shown in FIG. 1, the terminal device 2 transmits a content request to the information processing device 1, and the information processing device 1 accepts the content request from the terminal device 2 (step S1). The content request is transmitted from the terminal device 2 in response to an operation on the terminal device 2 by the user U. Such a content request includes, for example, a user ID (Identifier) that is an identifier of the user U, and the information processing device 1 identifies the user U based on the user ID included in the content request.

Upon receiving the content request from the terminal device 2, the information processing device 1 generates home content (step S2), and transmits the generated home content to the terminal device 2 (step S3). The terminal device 2 displays the home content transmitted from the information processing device 1, as shown in FIG. 1(a).

The home content shown in FIG. 1(a) includes a tab row and main tab content. The tab row includes a plurality of tabs, and each of these tabs is a GUI (Graphical User Interface) for switching and displaying displayed content. Each tab is an example of a tab that displays content of a specific category.

For example, the user U can add or delete the plurality of tabs included in the tab row, and can also set the order of the tabs. The tab setting information by the user U is stored in the information processing device 1, for example, and the information processing device 1 generates a tab string included in the home content based on the tab setting information by the user U. Note that, as described later, the tab setting information may be stored in the terminal device 2, and in this case, the tab row is generated by the terminal device 2.

The main tab content is default tab content, and as shown in FIG. 1(a), includes a plurality of news contents corresponding to the tab "All". Primary tab content is placed within the content area. The tab "All" is a tab for displaying multiple news contents that can be selected regardless of category, and in the state shown in FIG. 1(a), it is highlighted to indicate the selected state. .

The tab row in the home content shown in FIG. 1A includes a tab "All", a tab "Entertainment", a tab "Sports", a tab "Music", a tab "IT", and the like. User U can select a desired tab from a plurality of tabs included in the tab row. The tab "Entertainment" is a tab for displaying a news content group including a plurality of news contents included in the "Entertainment" category.

The tab "Sports" is a tab for displaying a news content group including a plurality of news contents included in the "Sports" category. The tab "Music" is a tab for displaying a news content group including a plurality of news contents included in the "Music" category. The tab "IT" is a tab for displaying a news content group including a plurality of news contents included in the "IT" category.

The news content included in the tab content is a headline content that includes a thumbnail and a title, and the user U selects the headline content by clicking or tapping, and selects the landing page, which is the news content linked to the headline content. Content can be displayed on the terminal device 2.

When the user U selects one tab from among the plurality of tabs included in the tab row, selection information including information indicating the tab selected by the user U is transmitted from the terminal device 2 to the information processing device 1 (step S4 ). This selection information includes the user U's user ID in addition to information indicating the tab selected by the user U.

When receiving the selection information from the terminal device 2, the information processing device 1 extracts a subcategory, which is a category obtained by classifying the selection category, which is a category specified by information indicating a tab included in the selection information (step S5).

For example, when the selected category is the category "music," subcategories of the selected category include J-POP, K-POP, anime songs, enka, jazz, classical, rap, R&B, and the like. Furthermore, when the selected category is the category "gourmet", subcategories of the selected category include Chinese food, Japanese food, French food, Italian food, Korean food, bread, ramen, pizza, and the like. A subcategory is a category that is a further classification of the category corresponding to a tab, and is an example of a category that is a further classification of a specific category.

In the process of step S5, the information processing device 1 extracts a plurality of subcategories based on predetermined extraction conditions. The predetermined extraction condition is, for example, a condition based on at least one of the action history of the user U and the number of news contents included in the subcategory.

For example, the information processing device 1 determines the degree of interest of the user U for each subcategory included in the selected category based on the behavior history of the user U, and determines the degree of interest of the user U for each subcategory included in the selected category, and selects the subcategory in which the degree of interest of the user U is equal to or higher than a threshold value, or the degree of interest of the user U. A predetermined number of subcategories are extracted in descending order of degree.

Further, the information processing device 1 can extract a predetermined number of subcategories in which the number of news contents belonging to the subcategory is greater than or equal to a threshold value, or in descending order of the number of news contents belonging to the subcategory. Note that the news content belonging to the subcategory is, for example, news content posted before a predetermined period of time.

Further, the information processing device 1 determines the user U's degree of interest in each subcategory included in the selected category based on the user U's behavior history, and selects news content for which the user U's degree of interest is equal to or higher than a threshold and belongs to the subcategory. It is also possible to extract subcategories in which the number of subcategories is greater than or equal to a threshold.

In the information processing device 1, the above-mentioned extraction conditions may be set for each attribute of the user U, or may be set for each subcategory, for example. Furthermore, the information processing device 1 can also extract subcategories using, for example, a learning model generated by machine learning that uses user U's information as input and outputs interest scores for each subcategory.

For example, the information processing device 1 inputs information about the user U specified by the selection information into a learning model, and extracts subcategories whose interest scores for each subcategory output from the learning model are equal to or higher than a threshold value. The interest score is an example of the degree of interest that the user U has, and the higher the degree of interest in a category, the higher the value.

The information on the user U that is input into the learning model is information on the user's U behavior history, but may also include information on the user's U attributes. Further, the information input to the learning model may include information indicating the number of news contents belonging to a subcategory, in addition to the information of the user U.

Subsequently, the information processing device 1 generates selection tab content (step S6). The selected tab content is, for example, information on a plurality of selected category contents, which are a plurality of news contents belonging to a category specified by information indicating a tab included in the selection information, and one or more subcategories extracted in step S5. Contains subcategory information. The subcategory information is a GUI in which one or more subcategories are arranged so that they can be selected by the user U, and includes subcategory thumbnails and selection buttons.

For example, the information indicating the tab included in the selection information is the information indicating the tab "Music", and the subcategories extracted in step S5 are the subcategory "Jazz", the subcategory "Rap", the subcategory "Anime Song", and the subcategory "Classical". ”.

In this case, the information processing device 1 generates selected tab content including news content belonging to the category "music" corresponding to the tab "music" and subcategory information corresponding to the category "music". The subcategory information corresponding to the category "Music" is, for example, information in which subcategories "Jazz", subcategories "Rap", subcategories "Anime songs", and subcategories "Classical" that are classified under the category "Music" are arranged in a selectable manner. be.

Subsequently, the information processing device 1 transmits the selected tab content generated in step S6 to the terminal device 2 (step S7). As shown in FIG. 1B, when the terminal device 2 acquires the selected tab content from the information processing device 1, it displays the acquired selected tab content.

The selection tab content shown in FIG. 1B includes a plurality of selection category contents belonging to the category "music" and subcategory information corresponding to the category "music". In the example shown in FIG. 1(b), the subcategory information corresponding to the category "music" is information in which subcategory "jazz", subcategory "rap", subcategory "anime song", and subcategory "classical" are arranged in a selectable manner. It is. User U can select one or more subcategories from among these multiple subcategories.

The terminal device 2 transmits selection information indicating that a subcategory has been selected by the user U from among the plurality of subcategories indicated by the subcategory information to the information processing device 1 (step S8). For example, when the user U selects the subcategory "Anime Song" shown in FIG. 1(b), the terminal device 2 transmits selection information indicating that the subcategory "Anime Song" has been selected to the information processing device 1. .

The information processing device 1 receives selection information indicating that a subcategory has been selected, and accepts the selection of the subcategory by the user U based on the received selection information (step S9). For example, if the received selection information is information indicating that the subcategory "anime song" has been selected, the information processing device 1 accepts the selection of the subcategory "anime song" by the user U.

Subsequently, the information processing device 1 generates selected tab content, which is information in which news content belonging to the subcategory for which the selection was accepted in step S9 is placed at a higher position in the content area (step S10).

For example, if the information indicates that the subcategory "Anime Song" has been selected, the information processing device 1 displays a selection tab that is information in which news content belonging to the subcategory "Anime Song" is placed at a higher position in the content area. Generate content.

Subsequently, the information processing device 1 transmits the selected tab content generated in step S10 to the terminal device 2 (step S11). Upon acquiring the selected tab content from the information processing device 1, the terminal device 2 displays the acquired selected tab content. Note that the information processing device 1 may transmit subcategory content, which will be described later, of the selected tab content to the terminal device 2, and cause the terminal device 2 to display the subcategory content, which will be described later.

As shown in FIG. 1(c), the selected tab content transmitted from the information processing device 1 to the terminal device 2 in step S11 is more user U-friendly than the selected tab content shown in FIG. 1(b). Contains subcategory content that is news content belonging to the selected subcategory "Anime Song."

In the subcategory information after the subcategory "Anime Song" is selected, as shown in Figure 1 (c), the heart shape in the information for the subcategory "Anime Song" is changed from unfilled to filled. . This allows the user U to understand that the subcategory "anime song" has been selected.

As shown in FIG. 1(c), subcategory content belonging to the subcategory "Anime Song" is news content belonging to the subcategory "Anime Song", and multiple selected category contents belonging to the category "Music" in the content area. is placed in a higher position. The upper position in the content area is the position where the user U can easily see the selected tab content when it is displayed on the terminal device 2, and in the content area shown in (c) of FIG. The higher the position, the higher the position.

In this way, since the subcategory content is ranked higher than the selected category content, the user U selects the news content that belongs to the subcategory that the user U is interested in from among the multiple subcategories into which the selected category is classified. This can be prioritized and grasped. Therefore, the information processing device 1 can improve convenience for the user U.

In the example shown in FIG. 1C, the subcategory "Anime Song" has one subcategory content, but the subcategory "Anime Song" may have two or more subcategory contents. For example, the information processing device 1 can increase the number of subcategory contents of the subcategory "anime song" as user U's degree of interest in the subcategory "anime song" increases.

In this case, the information processing device 1 may display a plurality of subcategory contents in the content area in a scrollable and selectable manner in the horizontal direction as shown in (c) of FIG. It is possible to display a carousel so that the direction can be selected.

Further, in the example shown in FIG. 1C, the number of subcategories selected by the user U is one, but the user U can select two or more subcategories. In this case, one or more subcategory contents of each of the two or more subcategories are arranged at a higher position than the selected category content within the content area.

When there are a plurality of subcategories selected from among a plurality of subcategories, the information processing device 1 arranges content belonging to a subcategory with a newer selection timing among the plurality of selected subcategories at a higher position in the content area.

Further, the information processing device 1 can also arrange the content in a subcategory in which the user U has a higher degree of interest, for example, so that the content is placed at a higher position in the content area. Furthermore, the information processing device 1 can also arrange the content so that the newer the selection timing and the higher the user U's interest in subcategory content, the higher the position in the content area.

Furthermore, when the user U performs an operation to update the selected tab content, the information processing device 1 updates the arrangement of the plurality of subcategories in the subcategory information. The selected tab content is updated by, for example, a swipe operation or scroll operation in a specific direction in the content area. The selected tab content can also be updated by, for example, pressing an update button (not shown) or reselecting a tab in a tab row.

When there is an update operation for the selected tab content, the information processing device 1 places the selected subcategory among the plurality of subcategories higher in the arrangement order than the unselected subcategories in the subcategory information.

For example, as shown in FIG. 1(d), in the subcategory information, the information processing device 1 replaces the selected subcategory "anime song" among the plurality of subcategories with the unselected subcategories "jazz" and "rap". , and order the array higher than "classic". In the arrangement order in FIG. 1(d), the further left the position, the higher the position.

Furthermore, when there are a plurality of subcategories selected among the plurality of subcategories, the information processing device 1 places the subcategory with the latest selection timing higher in the subcategory information among the plurality of selected subcategories. Further, the information processing device 1 can also arrange the subcategory information such that the subcategory with which the user U is more interested is placed at a higher position.

Further, the information processing device 1 can provide information in which a plurality of subcategories are selectably displayed in a carousel as subcategory information, or can provide subcategory information as information displayed in animation.

Animation display can be used, for example, to gradually increase the vertical size of subcategory information, such as a fade-in display, so that the subcategory information becomes gradually visible, or to display subcategory information, such as a slide-in display. This may be done by moving from outside the content area to the content area, but is not limited to this example.

The animation display only needs to be able to display the subcategory information so as to produce a visual effect. For example, the subcategory information may be inserted while being rotated or the subcategory information may be inserted while changing the size or shape of the subcategory information.

Note that in the above example, the subcategory was explained when the tab selected by the user U is a tab of a specific category, but the information processing device 1 also adds subcategory information to the tab content when the tab is "all". can be included.

In this case, the information processing device 1 estimates the category in which the user U is interested from among all the categories, which can be set in the tab row, but is not set in the tab row. Or, the category in which the user U is interested is estimated from among the plurality of tabs set in the tab row. Then, the information processing device 1 can generate subcategory information in which a plurality of categories estimated to be of interest to the user U are arranged in a selectable manner as a plurality of subcategories corresponding to the tab "All".

Further, the information processing device 1 can also estimate a subcategory in which the user U is interested from among a plurality of subcategories classified into categories corresponding to tabs that can be set in the tab row. Then, the information processing device 1 can generate subcategory information in which a plurality of subcategories estimated to be of interest to the user U are arranged in a selectable manner as a plurality of subcategories corresponding to the tab "All".

Further, a part of the home content shown in FIG. 1 may be generated by the terminal device 2 based on information stored in advance in the terminal device 2. For example, the tab setting information edited by the user U may be stored in the terminal device 2. In this case, the terminal device 2 selects the tab row of the home content based on the tab setting information by the user U. generate.

Further, in the above example, the information processing device 1 generates the home content and causes the terminal device 2 to display the home content, but the home content may be displayed by processing mainly performed by the terminal device 2. For example, the information processing device 1 provides a plurality of pieces of information (for example, news content) to the terminal device 2 based on information input from the terminal device 2 via an interface such as an API (Application Programming Interface), and 2 may generate and display home content based on a plurality of pieces of information provided from the information processing device 1. Further, although FIG. 1 shows a case where the terminal device 2 and the information processing device 1 are separate devices, the terminal device 2 and the information processing device 1 may be integrated.

In this way, the information processing device 1 receives the selection of a subcategory, which is a category in which the content to be displayed in the content area displayed by selecting a tab, and ranks the content belonging to the subcategory for which the selection has been accepted in the top ranking in the content area. Provides tab content, which is information placed at the location. Thereby, the information processing device 1 can improve convenience for the user U.

When accepting a tab row editing request, the receiving section 41 updates the setting information stored in the user information storage section 30 in response to the tab row editing request.

[4.3.3. Extraction part 42]
The extraction unit 42 extracts a plurality of subcategories based on predetermined extraction conditions. The predetermined extraction condition is, for example, a condition based on at least one of the action history of the user U and the number of news contents included in the subcategory.

For example, when selection information from the terminal device 2 is received by the reception unit 41, the extraction unit 42 selects a category that is specified by information indicating a tab included in the selection information based on predetermined extraction conditions. Extract subcategories, which are categories into which the selected category is classified.

In this case, the predetermined extraction condition is the action history of user U specified by the user ID included in the selection information and the number of news contents included in a subcategory that is a category of the selected category specified by the selection information. The condition is based on at least one of the following.

For example, when the selected category is the category "music," subcategories of the selected category include J-POP, K-POP, anime songs, enka, jazz, classical, rap, R&B, and the like. Furthermore, when the selected category is the category "gourmet", subcategories of the selected category include Chinese food, Japanese food, French food, Italian food, Korean food, bread, ramen, pizza, and the like. A subcategory is a category that is a further classification of the category corresponding to a tab, and is an example of a category that is a further classification of a specific category.

For example, the extraction unit 42 determines the degree of interest of the user U for each subcategory included in the selected category based on the behavior history of the user U, and selects subcategories in which the degree of interest of the user U is equal to or higher than a threshold value, or the degree of interest of the user U. A predetermined number of subcategories are extracted in descending order of their values.

Further, the extraction unit 42 can extract a predetermined number of subcategories in which the number of news contents belonging to the subcategory is greater than or equal to a threshold value, or a predetermined number of subcategories in descending order of the number of news contents belonging to the subcategory. Note that the news content belonging to the subcategory is, for example, news content posted before a predetermined period of time.

Furthermore, the extraction unit 42 determines the degree of interest of the user U for each subcategory included in the selected category based on the behavior history of the user U, and selects news content for which the degree of interest of the user U is equal to or higher than the threshold and belongs to the subcategory. Subcategories whose number is equal to or greater than a threshold can be extracted.

In the extraction unit 42, the above-mentioned extraction conditions may be set for each attribute of the user U, or may be set for each subcategory, for example. Further, the extraction of subcategories by the extraction unit 42 can also be performed using, for example, a learning model generated by machine learning that inputs information about the user U and outputs an interest score for each subcategory.

For example, the extraction unit 42 inputs information about the user U specified by the selection information into a learning model, and extracts subcategories whose interest scores for each subcategory output from the learning model are equal to or higher than a threshold value. The interest score is an example of the degree of interest that the user U has, and the higher the degree of interest in a category, the higher the value.

The information on the user U that is input into the learning model is information on the user's U behavior history, but may also include information on the user's U attributes. Further, the information input to the learning model may include information indicating the number of news contents belonging to a subcategory, in addition to the information of the user U.

A learning model that outputs an interest score for each subcategory is generated using, for example, a data set that includes, for each user U, data indicating a subcategory in which the user U is interested and information about the user U. The learning model is generated, for example, by machine learning using a neural network such as a convolutional neural network, a recurrent neural network, or a deep neural network, but is not limited to such examples. For example, instead of using a neural network, the learning model may be generated using machine learning using a learning algorithm such as linear regression or logistic regression.
