DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the information processing device, the information processing method, and the information processing program according to the present application will be described in detail with reference to the drawings. Note that the information processing device, the information processing method, and the information processing program according to the present application are not limited to the embodiments. In addition, the same components in the following embodiments are denoted by the same reference numerals, and duplicated descriptions are omitted.

[0010] [1. Overview of the information processing system] First, an overview of an information processing system according to an embodiment will be described with reference to Fig. 1. Fig. 1 is an explanatory diagram showing an overview of an information processing system according to an embodiment. As shown in Fig. 1, an information processing system 1 according to an embodiment includes a terminal device 10 and a server device 100. These various devices are connected to each other via a network N in a wired or wireless manner so as to be able to communicate with each other. This allows the terminal device 10 to cooperate with the server device 100. The network N is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network) such as the Internet.

[0011] The terminal device 10 is an information processing device used by a user U. For example, the terminal device 10 is a smart device such as a smartphone or a tablet terminal, a mobile phone such as a feature phone, a personal computer (PC), a personal digital assistant (PDA), a game machine or AV device equipped with a communication function, an information appliance or digital appliance, a car navigation system, a smart watch or a head-mounted display, a wearable device such as smart glasses, etc. The terminal device 10 may also be a house or building, a car, a home appliance, an electronic device, etc. that supports the Internet of Things (IOT).

[0012] In this embodiment, the terminal device 10 is a smart device such as a smartphone or tablet terminal used by a user U, and is a mobile terminal device that can communicate with any server device via a wireless communication network such as LTE (Long Term Evolution), 4G (4th Generation), or 5G (5th Generation: 5th generation mobile communication system). The terminal device 10 has a screen such as a liquid crystal display having a touch panel function, and accepts various operations on display data such as content, such as tapping, sliding, and scrolling, performed by a finger or a stylus from the user U. An operation performed on an area of ​​the screen where the content is displayed may be regarded as an operation on the content. The terminal device 10 may be not only a smart device, but also an information processing device such as a desktop PC (Personal Computer) or a notebook PC.

[0013] In addition, the terminal device 10 can connect to the network N via a wireless communication network such as LTE, 4G, or 5G, or short-range wireless communication such as Bluetooth (registered trademark) or wireless LAN (Local Area Network), and communicate with the server device 100.

[0014] The server device 100 is, for example, a computer such as a PC or a blade server, or a mainframe or a workstation, etc. The server device 100 may be realized by cloud computing.

[0015] In this embodiment, the server device 100 is an information processing device that cooperates with the terminal device 10 of each user U and provides API (Application Programming Interface) services for various applications (hereinafter, apps), etc., as well as various data, to the terminal device 10 of each user U, and is realized by a computer, a cloud system, etc.

[0016] The server device 100 may also be an information processing device that provides some kind of online Web service to the terminal device 10 of each user U. For example, the server device 100 may provide services such as Internet connection, search service, SNS (Social Networking Service), electronic commerce (EC), electronic payment, online games, online banking, online trading, hotel and ticket reservations, video and music distribution, news, maps, route search, route guidance, line information, operation information, and weather forecasts as Web services. In practice, the server device 100 may cooperate with various servers that provide the above-mentioned Web services, and may mediate the Web services or be responsible for processing the Web services.

[0017] The server device 100 can acquire user information about the user U. For example, the server device 100 acquires information about the attributes of the user U, such as the gender, age, and residential area of ​​the user U. The server device 100 then stores and manages the information about the attributes of the user U together with identification information (such as a user ID) indicating the user U.

[0018] The server device 100 also acquires various types of history information (log data) indicating the actions of the user U from the terminal device 10 of the user U or from various servers based on the user ID or the like. For example, the server device 100 acquires a location history, which is a history of the location and date and time of the user U, from the terminal device 10. The server device 100 also acquires a search history, which is a history of search queries input by the user U, from a search server (search engine). The server device 100 also acquires a browsing history, which is a history of content browsed by the user U, from a content server. The server device 100 also acquires a purchase history (payment history), which is a history of product purchases and payment processing by the user U, from an electronic commerce server or a payment processing server. The server device 100 may also acquire a listing history, which is a history of listings on the marketplace by the user U, and a sales history, from the electronic commerce server or the payment processing server. The server device 100 also acquires a posting history, which is a history of posts by the user U, from a posting server that provides a word-of-mouth posting service or an SNS server. The above-mentioned various servers and the like may be the server device 100 itself. That is, the server device 100 may function as the above-mentioned various servers and the like.

[0019] Furthermore, the number of devices included in the information processing system 1 shown in Fig. 1 is not limited to that shown in the figure. For example, in Fig. 1, for the sake of simplicity, only one terminal device 10 is shown, but this is merely an example and is not limiting, and two or more devices may be included.

[0020] [2. Deleting unnecessary content and generating recommendations] In this embodiment, the server device 100 allows the user U to specify whether to display (remain) or hide (delete) each piece of content that can be displayed in a list. At this time, the server device 100 displays tags related to the theme of the content to be hidden (deleted) along with the content to be hidden (deleted), and finally determines whether to display (remain) or hide (delete) the content according to the operation of the user U that refers to not only the content but also the tags.

[0021] FIG. 2 shows examples of content categories and tags. Note that in practice, a content category may also be one of the tags. For example, tags are attached to each piece of content related to a category as shown in FIG. 2. Note that tags may be added by a user U who has viewed the content. However, these categories and tags are merely examples. In practice, they are not limited to the categories and tags shown in FIG. 2.

[0022] In this embodiment, the article content of a news site / news app will be described as an example of one type of content, but in reality, the content is not limited to the article content of a news site / news app. For example, the content may be information that can be displayed in a list, such as posts on a video site or SNS, product information in an online mall, or search results.

[0023] 1, the server device 100 provides a screen displaying a list of article contents such as news (content list screen) to the terminal device 10 of the user U via the network N (step S1). For example, the server device 100 causes the terminal device 10 of the user U to display a screen displaying a list of article contents such as news, as shown in (A) of FIG.

[0024] Next, the server device 100 accepts an operation (deletion operation) by the user U on the delete button B (an "x" mark) displayed together with each article content on the screen displaying a list of article contents such as news (step S2).

[0025] Next, the server device 100 presents a deletion screen for the article content that the user U has pressed the delete button B ("x" mark) to perform the deletion operation, together with tags related to the article content (step S3). In other words, just because the user U has pressed the delete button B ("x" mark) to perform the deletion operation, the article content is not immediately deleted, but the deletion screen for the article content is opened, tags are displayed, and the user is prompted to confirm whether or not to actually delete the article content and perform the operation.

[0026] For example, as shown in FIG. 1B, the server device 100 displays several tags indicating the theme T of the article content on the deletion screen of the article content together with a message M saying "This article will be hidden." It is assumed that tags are assigned in advance to each article content. The theme T of the article content may be determined by a combination of tags. Furthermore, the tags may be assigned by a user (viewer) who has viewed the article content. For example, the server device 100 may accept the assignment of tags to the article content from a user who has viewed the article content.

[0027] Next, the user U looks at the tag displayed on the deletion screen for the article content, and refers (considers) the tag to determine whether or not to delete the article content. The server device 100 accepts the operation performed by the user U using the terminal device 10 via the network N (step S4). Note that even if the user U initially intends to delete the article content, he or she may change his or her mind after referring to the tag and cancel the deletion of the article content.

[0028] For example, as shown in (B) of FIG. 1, when a user U swipes the article content to the left of the screen, the server device 100 hides (deletes) the article content (similar article content) belonging to the theme indicated by the article content, and when the user U swipes the article content to the upper side of the screen, the server device 100 leaves (does not delete) the article content belonging to the theme indicated by the article content. If the user U is unable (unsure) at that point whether to display (remain) or hide (delete) the article content, the user U can put the article content on hold (under consideration) by swiping to the right of the screen. The above swipe direction and operation result contents (delete, leave, hold, etc.) are merely examples. For example, the server device 100 may arbitrarily set the swipe direction and operation result, or may set other operation contents.

[0029] Alternatively, the server device 100 may be configured to erase the article content when the user U performs an operation to agree to the erasure of the article content. Conversely, the server device 100 may be configured to cancel the erasure of the article content when the user U performs an operation to cancel the erasure of the article content. At this time, the server device 100 may inquire of the user U, such as "Do you really want to erase the article content?", and allow the user U to respond with "Yes" (Yes / OK) or "No."

[0030] Next, the server device 100 extracts and selects candidates (candidate contents) of article contents to be deleted next in relation to the article contents or tags, and presents the tags attached to the candidate contents together with a deletion screen for the candidate contents (step S5). After this, the operations of steps S4 to S5 are repeated until there are no more candidates (candidate contents) of article contents to be deleted next (or until the user U interrupts the process). Note that an upper limit may be set for the number of candidate contents. Alternatively, the server device 100 may display a list of candidates of article contents to be deleted, allowing the user U to delete them all at once by judgment and operation.

[0031] Next, when there are no more candidates for the next article content to be deleted, the server device 100 provides the terminal device 10 of the user U via the network N with a content list screen after all the article content for which the deletion operation has been performed has been deleted (step S6). For example, as shown in FIG. 1C, the server device 100 causes the terminal device 10 of the user U to display the content list screen after deletion.

[0032] [2-1. Adjusting recommendations by manipulating tags] As another example, in the present embodiment, the server device 100 may allow the user U to operate the tag displayed on the deletion screen to delete or retain the article content and other article content related to the tag collectively, thereby adjusting the recommendation. In this case, the server device 100 collectively determines whether to display (retain) or hide (delete) other content related to the same theme (having the same tag) in response to the operation of the user U who viewed the tag (also referred to the tag).

[0033] For example, in (B) of FIG. 1, when a user U swipes a tag to the left side of the screen, the server device 100 hides (deletes) article content (similar article content) belonging to the theme indicated by the tag, and when the user U swipes the tag to the top of the screen, the server device 100 leaves article content belonging to the theme indicated by the tag. If the user U is unable (unsure) at that point whether to display (remain) or hide (delete) the tag, the user U can swipe the tag to the right side of the screen to "hold" (under consideration). The above swipe direction and operation result (delete, leave, hold, etc.) are merely examples. In practice, any direction and operation result may be set. The user U may also be able to specify the theme he or she wants to keep by tapping the tag.

[0034] If the user U does not perform any tag operation on the deletion screen, the server device 100 may hide (delete) only the article content. That is, the server device 100 hides (deletes) only the article content for which a deletion operation was first received, without affecting article contents belonging to the same theme (similar article contents).

[0035] Next, the server device 100 changes the content list screen in response to the tag operation by the user U. In this case, the server device 100 switches from the original content list screen to a content list screen that displays article content having a tag that the user U operated to "keep" and deletes article content having a tag that the user U operated to "delete." This changes the candidate article content to be displayed on the content list screen. Furthermore, as the candidate article content is replaced, the tags are also replaced, and new sorting tags appear.

[0036] At this time, the server device 100 may display a preview of the changed content list screen, and switch to the changed content list screen if the user U agrees to the change.

[0037] Furthermore, the server device 100 may present to the user U in real time (or in advance) candidate article content (similar article content) to be deleted by the operation for "deleting". Furthermore, the server device 100 may present to the user U in real time (or in advance) candidate article content / article content that is changed by the operation for "keeping" or the "above-mentioned tag operation".

[0038] In addition, the server device 100 may not only "reduce similar article content" when user U performs an operation to "delete" a tag, but may also "increase similar article content" by digging deeper into the article content having the tag when user U performs an operation to "keep" a tag.

[0039] In addition, when providing a content list screen changed in response to the tag operation by user U, the server device 100 displays article content having a tag that user U operated to "keep," and displays a content list screen on user U's terminal device 10 in which article content having a tag that user U operated to "delete" has been erased.

[0040] [2-2. Additional features] The server device 100 may also have a function of reviewing the status (delete / keep / reserve) of article contents and tags set by the user U. For example, the server device 100 may store the operation history of the article contents and tags set by the user U.

[0041] Furthermore, the server device 100 may learn the article content that the user U selected to delete, the tags that the user U operated, and the details of the operation by machine learning.Then, the server device 100 may use a model obtained as a result of the learning to predict the article content that the user U is likely to select to delete and the tags that the user U is likely to operate, and reflect the predictions in the subsequent content list screens.

[0042] Furthermore, the server device 100 may read the "tag contents" and "content information" belonging to the article content that the user U has decided to delete, and display new "candidate content for deletion." For example, if the user U has decided to delete "article content a," the server device 100 processes "article content c" with "tag A" belonging to it as having been deleted (it is not displayed on the terminal device 10 of the user U), and displays "article content b" with "tag B" that is next most related to tag A as a new "candidate content for deletion" on the terminal device 10 of the user U.

[0043] Furthermore, the server device 100 may reflect on the content list screen the operations of article contents and tags not only by the user U (the user himself / herself) but also by other users having the same attributes as the user U (or other users belonging to the same segment). For example, the server device 100 may identify a user group having attributes such as demographics (demographic attributes), psychographics (psychological attributes), geographics (geographic attributes), behavioral attributes, etc. in common with the user U, tally up tag operations for each article content, and change the content list screen according to the most frequently performed operation among the user group.

[0044] Furthermore, the server device 100 may set an expiration date for the operation of the user U on the article content and tags, and initialize them after a predetermined period has passed. For example, even if the user U has deleted article content or tags because he / she was not interested in them in the past, the user U may become interested in them in the future due to subsequent major news or the activities of related parties. Therefore, the server device 100 may initialize the settings every time a predetermined period has passed, and once again confirm with the user U whether to delete the article content or tags.

[0045] Furthermore, even if the user U performs an operation to hide (delete) article content or tags, the server device 100 may exceptionally display article content that is currently major news in the world (such as article content with a threshold number of viewers). At this time, it may be clearly indicated that the display is exceptional. Furthermore, when the user U performs an operation to hide (delete) article content or its tag that was displayed exceptionally, the server device 100 may not display article content with that tag (similar article content) thereafter, even if the article content is currently major news in the world.

[0046] [2-3. Other Perspectives] In the above, the case of "deleting" article content is described, but the opposite case of "increasing" (adding) is also similar. For example, instead of the "delete button" (or together with the "delete button"), an "increase button" may be provided so that the content can be increased in the same procedure as for deleting. Alternatively, in (B) of FIG. 1, when the user U swipes an article content or a tag downward on the screen, the server device 100 may increase other article content related to the article content or article content belonging to the theme indicated by the tag (similar article content). Note that the specific operation for "increasing" can be set arbitrarily. However, in practice, it is not limited to these examples.

[0047] In addition, even if user U initially intends to delete the article content, he / she may change his / her mind after referring to the tags and cancel the deletion of the article content, or conversely, may wish to increase similar article content. The opposite is also possible.

[0048] In this embodiment, in the news article content list, the user U can select article content to be added or deleted. The server device 100 also presents the article content that the user U selected to delete, along with the reason why the article content will remain or disappear in the form of a tag. The user U can also control the reason why the article content will remain or disappear by manipulating the tag.

[0049] At this time, when the user U selects the article content to be deleted, the server device 100 may display the article content that will be deleted together (similar article content) and the reason why the article content will be deleted together. The reason is displayed in the form of a tag. If the user U does not want the similar article content to be deleted together, he or she can select to keep it by manipulating the tag. In that case, the target article content (similar article content) will remain. Note that there may be a function to increase similar article content as well as a function to increase similar article content.

[0050] The server device 100 may also allow article contents and tags to be set as "necessary" or "unnecessary." The server device 100 may also learn necessary and unnecessary tags from the above. The server device 100 may also use a model obtained as a result of the learning to infer necessary and unnecessary tags and suggest them to the user U.

[0051] [3. Example of terminal device configuration] Next, the configuration of the terminal device 10 will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the configuration of the terminal device 10. As shown in Fig. 3, the terminal device 10 includes a communication unit 11, a display unit 12, an input unit 13, a positioning unit 14, a sensor unit 20, a control unit 30 (controller), and a storage unit 40.

[0052] (Communications Department 11) The communication unit 11 is connected to the network N by wire or wirelessly, and transmits and receives information to and from the server device 100 via the network N. For example, the communication unit 11 is realized by a NIC (Network Interface Card), an antenna, or the like.

[0053] (Display section 12) The display unit 12 is a display device that displays various information such as position information. For example, the display unit 12 is a liquid crystal display (LCD) or an organic electro-luminescent display (OLED). The display unit 12 is a touch panel display, but is not limited to this.

[0054] (Input section 13) The input unit 13 is an input device that accepts various operations from the user U. For example, the input unit 13 has buttons for inputting characters, numbers, and the like. The input unit 13 may be an input / output port (I / O port), a USB (Universal Serial Bus) port, or the like. In addition, when the display unit 12 is a touch panel display, a part of the display unit 12 functions as the input unit 13. In addition, the input unit 13 may be a microphone that accepts voice input from the user U, or the like. The microphone may be wireless.

[0055] (Positioning unit 14) The positioning unit 14 receives a signal (radio wave) transmitted from a satellite of a GPS (Global Positioning System), and acquires position information (e.g., latitude and longitude) indicating the current position of the terminal device 10, which is the device itself, based on the received signal. That is, the positioning unit 14 measures the position of the terminal device 10. Note that the GPS is merely an example of a GNSS (Global Navigation Satellite System).

[0056] The positioning unit 14 can measure the position by various methods other than GPS. For example, the positioning unit 14 may measure the position by using various communication functions of the terminal device 10 as described below as an auxiliary positioning means for position correction or the like.

[0057] (Wi-Fi positioning) For example, the positioning unit 14 uses a Wi-Fi (registered trademark) communication function of the terminal device 10 or a communication network provided by each communication company to measure the position of the terminal device 10. Specifically, the positioning unit 14 performs Wi-Fi communication or the like and measures the distance to a nearby base station or access point to measure the position of the terminal device 10.

[0058] (Beacon positioning) The positioning unit 14 may measure the position by using a Bluetooth (registered trademark) function of the terminal device 10. For example, the positioning unit 14 measures the position of the terminal device 10 by connecting to a beacon transmitter connected by the Bluetooth (registered trademark) function.

[0059] (geomagnetic positioning) The positioning unit 14 also measures the position of the terminal device 10 based on a geomagnetic pattern of a structure measured in advance and a geomagnetic sensor included in the terminal device 10.

[0060] (RFID positioning) Furthermore, for example, if the terminal device 10 has a function of an RFID (Radio Frequency Identification) tag equivalent to a contactless IC card used at station ticket gates, stores, etc., or has a function of reading an RFID tag, the location of use is recorded together with information on a payment or the like made by the terminal device 10. The positioning unit 14 may obtain such information to measure the location of the terminal device 10. Furthermore, the location may be measured by an optical sensor, an infrared sensor, or the like provided in the terminal device 10.

[0061] The positioning unit 14 may, if necessary, measure the position of the terminal device 10 using one or a combination of the above-mentioned positioning means.

[0062] (Sensor unit 20) The sensor unit 20 includes various sensors mounted on or connected to the terminal device 10. The connection may be wired or wireless. For example, the sensors may be detection devices other than the terminal device 10, such as wearable devices and wireless devices. In the example shown in FIG. 3, the sensor unit 20 includes an acceleration sensor 21, a gyro sensor 22, an air pressure sensor 23, a temperature sensor 24, a sound sensor 25, a light sensor 26, a magnetic sensor 27, and an image sensor (camera) 28.

[0063] The above-mentioned sensors 21 to 28 are merely examples and are not intended to be limiting. That is, the sensor unit 20 may be configured to include some of the sensors 21 to 28, or may include other sensors such as a humidity sensor in addition to or instead of the sensors 21 to 28.

[0064] The acceleration sensor 21 is, for example, a three-axis acceleration sensor, and detects physical movements of the terminal device 10, such as the moving direction, speed, and acceleration of the terminal device 10. The gyro sensor 22 detects physical movements of the terminal device 10, such as tilts in three axial directions, based on the angular velocity, etc. of the terminal device 10. The air pressure sensor 23 detects, for example, the air pressure around the terminal device 10.

[0065] Since the terminal device 10 includes the above-mentioned acceleration sensor 21, gyro sensor 22, and air pressure sensor 23, it is possible to measure the position of the terminal device 10 using a technique such as Pedestrian Dead-Reckoning (PDR) that uses these sensors 21 to 23. This makes it possible to obtain indoor position information that is difficult to obtain using a positioning system such as GPS.

[0066] For example, the number of steps, walking speed, and distance walked can be calculated by a pedometer using the acceleration sensor 21. In addition, the moving direction, line of sight direction, and body inclination of the user U can be known by using the gyro sensor 22. In addition, the altitude and floor number on which the terminal device 10 of the user U is located can be known from the air pressure detected by the air pressure sensor 23.

[0067] The air temperature sensor 24 detects, for example, the air temperature around the terminal device 10. The sound sensor 25 detects, for example, the sound around the terminal device 10. The light sensor 26 detects the illuminance around the terminal device 10. The magnetic sensor 27 detects, for example, the geomagnetism around the terminal device 10. The image sensor 28 captures an image around the terminal device 10.

[0068] The above-mentioned air pressure sensor 23, temperature sensor 24, sound sensor 25, light sensor 26, and image sensor 28 can detect the air pressure, temperature, sound, and illuminance, and capture images of the surroundings, thereby detecting the environment and situation around the terminal device 10. In addition, the accuracy of the location information of the terminal device 10 can be improved based on the environment and situation around the terminal device 10.

[0069] (Control unit 30) The control unit 30 includes, for example, a microcomputer having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM, an input / output port, and various other circuits. The control unit 30 may also be configured with hardware such as an integrated circuit, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). The control unit 30 includes a transmitting unit 31, a receiving unit 32, and a processing unit 33.

[0070] (Transmitter 31) The transmission unit 31 can transmit, for example, various information input by the user U using the input unit 13, various information detected by each sensor 21-28 mounted on or connected to the terminal device 10, and location information of the terminal device 10 measured by the positioning unit 14 to the server device 100 via the communication unit 11.

[0071] (Receiving unit 32) The receiving unit 32 can receive various types of information provided by the server device 100 and requests for various types of information from the server device 100 via the communication unit 11.

[0072] (Processing section 33) The processing unit 33 controls the entire terminal device 10, including the display unit 12, etc. For example, the processing unit 33 can output various information transmitted by the transmission unit 31 and various information received from the server device 100 by the reception unit 32 to the display unit 12 for display.

[0073] (Storage unit 40) The storage unit 40 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk drive (HDD), a solid state drive (SSD), an optical disk, etc. Various programs and various data are stored in the storage unit 40.

[0074] [4. Example of Server Device Configuration] Next, the configuration of the server device 100 according to the embodiment will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of the configuration of the server device 100 according to the embodiment. As shown in Fig. 4, the server device 100 includes a communication unit 110, a storage unit 120, and a control unit 130.

[0075] (Communication unit 110) The communication unit 110 is realized by, for example, a network interface card (NIC), etc. The communication unit 110 is also connected to a network N in a wired or wireless manner.

[0076] (Storage unit 120) The storage unit 120 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a HDD, an SSD, an optical disk, etc. The storage unit 120 may store attribute information and history information (log data) of the user U together with identification information (such as a user ID) indicating the user U.

[0077] (Control unit 130) The control unit 130 is a controller, and is realized by, for example, a central processing unit (CPU), a micro processing unit (MPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., executing various programs (corresponding to an example of an information processing program) stored in a storage device inside the server device 100 using a storage area such as a RAM as a working area. In the example shown in FIG. 4, the control unit 130 has an acquisition unit 131, a display control unit 132, an operation acceptance unit 133, a tag display unit 134, and a tag assignment unit 135.

[0078] (Acquisition part 131) The acquisition unit 131 acquires a search query input by a user U (user). For example, when the user U inputs a search query into a search engine or the like to perform a keyword search, the acquisition unit 131 acquires the search query via the communication unit 110. That is, the acquisition unit 131 acquires, via the communication unit 110, a keyword input by the user U into a search box of a search engine, a site, or an app.

[0079] Furthermore, the acquisition unit 131 acquires user information regarding the user U via the communication unit 110. For example, the acquisition unit 131 acquires identification information (such as a user ID) indicating the user U, location information of the user U, attribute information of the user U, and the like from the terminal device 10 of the user U. Furthermore, the acquisition unit 131 may acquire the identification information indicating the user U, attribute information of the user U, and the like when the user U is registered. Then, the acquisition unit 131 stores the user information in the storage unit 120.

[0080] Furthermore, the acquisition unit 131 acquires various types of history information (log data) indicating the behavior of the user U via the communication unit 110. For example, the acquisition unit 131 acquires various types of history information indicating the behavior of the user U from the terminal device 10 of the user U, or from various servers based on a user ID or the like. Then, the acquisition unit 131 stores the various types of history information in the storage unit 120.

[0081] Furthermore, the acquisition unit 131 acquires, via the communication unit 110, operation information related to the content (articles, etc.) deleted by the user U and the tag operation performed by the user U. Then, the acquisition unit 131 stores the operation information in the storage unit 120. Furthermore, the acquisition unit 131 may acquire, via the communication unit 110, the content itself or information required for creating the content from a provider of the content (article content such as news, etc.).

[0082] (Display control unit 132) The display control unit 132 displays a list screen of contents (article contents such as news, etc.). At this time, the display control unit 132 may determine the layout, display position / display order, size, display image, display content, etc. of the contents (articles, etc.) to create the list screen, and transmit information about the list screen to the terminal device 10 of the user U.

[0083] (Operation reception unit 133) The operation receiving unit 133 receives an operation to delete (such as pressing a delete button) or to increase (such as pressing an increase button) any of the contents displayed on the list screen from the user U. For example, the operation receiving unit 133 receives an operation (delete operation) by the user U on the delete button B (an "x" mark) displayed together with each piece of content (such as an article) on a screen that displays a list of news or other content.

[0084] (Tag display section 134) The tag display unit 134 displays the tag attached to the content for which a deletion operation or an increase operation has been accepted together with the content. At this time, the tag display unit 134 may express the theme of the content by a combination of tags. The tag display unit 134 may also analyze the content by image recognition, natural language processing (NLP), or the like, create a new tag, and display the new tag together with the content for which a deletion operation or an increase operation has been accepted.

[0085] Then, the operation receiving unit 133 receives an operation for the content from the user U who has viewed the displayed tag.

[0086] For example, when a user U who sees a displayed tag moves the content in a particular direction (e.g., to the left side of the screen) and moves it off the screen, the operation receiving unit 133 receives this as an operation to erase the content from the list screen.

[0087] In addition, when a user U who sees a displayed tag moves the content in a specific direction (e.g., toward the top of the screen) and moves it off the screen, the operation receiving unit 133 receives this as an operation to leave the content on the list screen.

[0088] In addition, when a user U who has seen a displayed tag operates to move the content in a specific direction (for example, to the right side of the screen) and off the screen, the operation receiving unit 133 receives this as an operation to reserve the decision as to whether to leave the content on the list screen or to erase it.

[0089] In addition, when a user U who sees a displayed tag moves the content in a specific direction (e.g., downward on the screen) and off the screen, the operation receiving unit 133 receives this as an operation to add (increase) similar content to the content in question to the list screen.

[0090] The display control unit 132 changes the contents of the content list screen in response to an operation on the content, and displays the changed content list screen.

[0091] Furthermore, when an operation is performed on a content, the tag display unit 134 displays the tag attached to the candidate content together with the candidate content (candidate content) of the content to be deleted or added next in relation to the content. At this time, the operation accepting unit 133 accepts an operation on the candidate content from a user who has seen the displayed tag. The display control unit 132 changes the contents of the content list screen in response to the operation on the candidate content, and displays the changed content list screen.

[0092] Furthermore, the operation receiving unit 133 receives an operation for a tag attached to a content. At this time, the operation receiving unit 133 receives an operation for deleting all of the tagged similar content from the list screen.

[0093] For example, when a user U who sees a displayed tag moves the tag in a specific direction (e.g., to the left side of the screen) and moves it off the screen, the operation receiving unit 133 receives this as an operation to erase all similar contents to which the tag has been attached from the list screen.

[0094] In addition, when a user U who sees a displayed tag moves the tag in a specific direction (e.g., toward the top of the screen) and moves it off the screen, the operation receiving unit 133 receives this as an operation to leave the tagged similar content on the list screen.

[0095] In addition, when a user U who sees a displayed tag moves the tag in a specific direction (for example, to the right side of the screen) and moves it off the screen, the operation receiving unit 133 accepts this as an operation to reserve the decision as to whether to leave the tagged similar content on the list screen or to delete it.

[0096] In addition, when a user U who sees a displayed tag moves the tag in a specific direction (e.g., toward the bottom of the screen) and off the screen, the operation receiving unit 133 receives this as an operation to add (increase) similar content with the tag to the list screen.

[0097] Furthermore, when (or before) the content of the content list screen is changed in response to an operation on a tag, the display control unit 132 may present the content affected by the operation on the tag in real time (or in advance).

[0098] In addition, the display control unit 132 also controls the display of similar contents tagged in response to an operation on the tag, and changes the contents of the content list screen. For example, the display control unit 132 erases all of the tagged similar contents from the list screen in response to an operation on the tag.

[0099] The display control unit 132 reduces the number of similar contents displayed on the content list screen in response to an operation on a tag. For example, when similar contents having the same tag are deleted all at once, the number of similar contents displayed on the content list screen is reduced. In this case, even if similar contents have the same tag, they are not necessarily articles about the same subject matter (incidents, incidents, people, etc.).

[0100] Alternatively, the display control unit 132 increases the number of similar contents to be displayed on the content list screen in response to the operation on the tag. For example, when a space is created for the deleted content, the number of similar contents to the remaining content to be displayed can be increased. Also, similar contents having the tag for which the operation to keep has been performed can be further searched for and displayed on the list screen.

[0101] (Tag assignment unit 135) The tag assigning unit 135 accepts an operation for assigning a tag to the content from a user U who has viewed the content, and assigns a tag to the content.

[0102] 5. Processing Procedure Next, a processing procedure by the server device 100 according to the embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart showing the processing procedure according to the embodiment. The processing procedure described below is repeatedly executed by the control unit 130 of the server device 100. Here, for simplicity of explanation, only the case of "deleting" will be explained. Note that, although the case of "deleting" content is explained below, the opposite case of "increasing" (adding) content is also similar.

[0103] For example, as shown in FIG. 5, the display control unit 132 of the server device 100 causes the terminal device 10 of the user U to display a list screen of contents (article contents such as news) via the communication unit 110 (step S101).

[0104] Next, the operation accepting unit 133 of the server device 100 accepts, via the communication unit 110, an operation to delete any one of the contents displayed on the list screen from the terminal device 10 of the user U (step S102).

[0105] Next, the tag display unit 134 of the server device 100 causes the terminal device 10 of the user U to display, via the communication unit 110, the tag attached to the content, together with the content for which the operation to delete has been accepted (step S103).

[0106] Furthermore, the tag attachment unit 135 of the server device 100 determines whether an operation for attaching a tag to the content has been received from the user U who has viewed the content (step S104).

[0107] When the tagging unit 135 of the server device 100 receives an operation for tagging the content from the user U who has viewed the content (step S104: Yes), the tagging unit 135 adds a tag to the content (step S105).

[0108] Next, the operation receiving unit 133 of the server device 100 receives an operation for the content or the tag from the terminal device 10 of the user U via the communication unit 110 (step S106).

[0109] Next, the display control unit 132 of the server device 100 checks whether there are candidates for the next content to be deleted (candidate contents) after the operation on the content or tag is performed (step S107). If there are candidate contents (step S107: Yes), the display control unit 132 repeats the above-mentioned processes of steps S103 to S106 on the candidate contents (return to the above-mentioned step S103) until there are no more candidate contents (or until the user U interrupts the process). An upper limit may be set on the number of candidate contents.

[0110] Next, if there is no / no candidate content (step S107: No), the display control unit 132 of the server device 100 changes the content list screen in accordance with the operation on the content or tag, and displays the changed content list screen on the terminal device 10 of the user U (step S108).

[0111] 6. Modifications The above-described terminal device 10 and server device 100 may be implemented in various different forms other than the above-described embodiment. Therefore, the following describes modifications of the embodiment.

[0112] In the above embodiment, some or all of the processing executed by the server device 100 may actually be executed by the terminal device 10. For example, the processing may be completed in a stand-alone manner (by the terminal device 10 alone). In this case, the terminal device 10 is assumed to have the functions of the server device 100 in the above embodiment. Also, in the above embodiment, since the terminal device 10 works in conjunction with the server device 100, from the perspective of the user U, it appears that the processing of the server device 100 is also executed by the terminal device 10. In other words, from another perspective, it can be said that the terminal device 10 is equipped with the server device 100.

[0113] Furthermore, in the above embodiment, the server device 100 may reflect on the content list screen tag operations made by not only the user U (the user himself / herself) but also a person in a position to supervise the user U (for example, a parent, a teacher, an employer, a system administrator, etc.). For example, when the user U uses the terminal device 10 lent / provided by a person in a position to supervise the user U, the person in a position to supervise the user U may perform operations on article contents and tags so that the user U does not view unnecessary / undesirable articles. Furthermore, the operation contents / settings made by a person in a position to supervise the user U may not be changed by the user U without permission from the person who made the setting (a person in a position to supervise the user U).

[0114] In the above embodiment, when the user U performs an operation to "keep" or "delete" tags, the server device 100 may leave only articles that satisfy all of the remaining tag combinations. In other words, the server device 100 may leave only articles that match the changed theme.

[0115] 7. Effects As described above, the information processing device (terminal device 10 or server device 100) of the present application comprises a display control unit 132 that displays a content list screen, an operation receiving unit 133 that receives from a user U an operation to delete or add any content from among the contents displayed on the list screen, and a tag display unit 134 that displays tags attached to the content together with the content for which an operation to delete or add has been received, and is characterized in that the operation receiving unit 133 receives an operation on the content from a user U who has seen the displayed tag, and the display control unit 132 changes the contents of the content list screen in accordance with the operation on the content and displays the changed content list screen.

[0116] When an operation is performed on the content, the tag display unit 134 displays the tag attached to the candidate content together with the candidate content to be next deleted or added in relation to the content. The operation accepting unit 133 accepts an operation on the candidate content from the user U who has seen the displayed tag. The display control unit 132 changes the contents of the content list screen in response to the operation on the candidate content, and displays the changed content list screen.

[0117] The operation receiving unit 133 receives an operation for a tag attached to a content. The display control unit 132 changes the contents list screen according to the operation for the tag, and displays the changed contents list screen.

[0118] When the tag is moved in a specific direction and moved off the screen, the operation receiving unit 133 receives the operation as an operation for erasing all of the tagged similar contents from the list screen.

[0119] When the tag is moved in a specific direction and moved off the screen, the operation receiving unit 133 receives the operation as an operation for leaving the tagged similar content on the list screen.

[0120] When the tag is moved in a specific direction and removed from the screen, the operation receiving unit 133 receives the tag as an operation for deferring a decision on whether to leave the tagged similar content on the list screen or to delete it.

[0121] When a tag is moved in a specific direction and is taken off the screen, the operation receiving unit 133 receives the operation as an operation for adding (increasing) similar content to which the tag is attached to the list screen.

[0122] The operation receiving unit 133 receives an operation for a tag attached to the content. The display control unit 132 reduces the number of similar contents displayed on the content list screen in response to the operation for the tag.

[0123] The operation receiving unit 133 receives an operation for a tag attached to a content. The display control unit 132 increases the number of similar contents displayed on the content list screen in response to the operation for the tag.

[0124] The information processing device according to the present application further includes a tagging unit 135 that receives an operation for tagging the content from a user U who has viewed the content, and tags the content.

[0125] By using any one or a combination of the above-mentioned processes, the information processing device according to the present application can more effectively increase or decrease the number of articles in the article list. For example, it is possible to delete unnecessary articles from the article list and hide them. Also, when the user U performs an operation to increase the number of articles, it is possible to increase the number of suitable articles in the list according to the user U's intention.

[0126] [8. Hardware Configuration] Moreover, the terminal device 10 and the server device 100 according to the above-described embodiment are realized by a computer 1000 having a configuration as shown in Fig. 6, for example. The server device 100 will be described below as an example. Fig. 6 is a diagram showing an example of a hardware configuration. The computer 1000 is connected to an output device 1010 and an input device 1020, and has a configuration in which a calculation device 1030, a primary storage device 1040, a secondary storage device 1050, an output I / F (Interface) 1060, an input I / F 1070, and a network I / F 1080 are connected by a bus 1090.

[0127] The arithmetic device 1030 operates based on programs stored in the primary storage device 1040 and the secondary storage device 1050, programs read from the input device 1020, and the like, and executes various processes. The arithmetic device 1030 is realized by, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like.

[0128] The primary storage device 1040 is a memory device such as a RAM (Random Access Memory) that primarily stores data used by the arithmetic device 1030 for various calculations. The secondary storage device 1050 is a storage device in which data used by the arithmetic device 1030 for various calculations and various databases are registered, and is realized by a ROM (Read Only Memory), an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flash memory, or the like. The secondary storage device 1050 may be an internal storage device or an external storage device. The secondary storage device 1050 may be a removable storage medium such as a USB (Universal Serial Bus) memory or an SD (Secure Digital) memory card. The secondary storage device 1050 may be a cloud storage (online storage), a NAS (Network Attached Storage), a file server, or the like.

[0129] The output I / F 1060 is an interface for transmitting information to be output to an output device 1010 that outputs various types of information, such as a display, a projector, a printer, etc., and is realized by a connector conforming to a standard such as USB (Universal Serial Bus), DVI (Digital Visual Interface), or HDMI (registered trademark) (High Definition Multimedia Interface). The input I / F 1070 is an interface for receiving information from various input devices 1020, such as a mouse, a keyboard, a keypad, a button, a scanner, etc., and is realized by a USB, etc.

[0130] Furthermore, the output I / F 1060 and the input I / F 1070 may be wirelessly connected to the output device 1010 and the input device 1020, respectively. That is, the output device 1010 and the input device 1020 may be wireless devices.

[0131] The output device 1010 and the input device 1020 may be integrated into one device, such as a touch panel. In this case, the output I / F 1060 and the input I / F 1070 may also be integrated into one device, such as an input / output I / F.

[0132] The input device 1020 may be a device that reads information from, for example, an optical recording medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), or a PD (Phase change rewritable Disk), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory.

[0133] The network I / F 1080 receives data from other devices via the network N and sends it to the arithmetic device 1030, and also transmits data generated by the arithmetic device 1030 to other devices via the network N.

[0134] The arithmetic unit 1030 controls the output device 1010 and the input device 1020 via the output I / F 1060 and the input I / F 1070. For example, the arithmetic unit 1030 loads a program from the input device 1020 or the secondary storage device 1050 onto the primary storage device 1040 and executes the loaded program.

[0135] For example, when the computer 1000 functions as the server device 100, the arithmetic unit 1030 of the computer 1000 executes a program loaded onto the primary storage device 1040 to realize the functions of the control unit 130. The arithmetic unit 1030 of the computer 1000 may also load a program acquired from another device via the network I / F 1080 onto the primary storage device 1040 and execute the loaded program. The arithmetic unit 1030 of the computer 1000 may also cooperate with the other device via the network I / F 1080 and use functions and data of a program by calling them from another program of the other device.
