[0009] Hereinafter, an information processing device, an information processing method, and an information processing program according to the present application (hereinafter referred to as "embodiments") 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 these embodiments. Furthermore, the same components in the following embodiments will be denoted by the same reference numerals, and duplicated descriptions will be omitted.

[0010] [1. An example of information processing] First, an example of information processing according to the embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of information processing according to the embodiment, which is executed by an information processing device 100. Note that Fig. 1 will be described by taking as an example a case where comments posted by viewing users and reaction inputs are acquired for each email content, and the acquired posted comments and input reactions are provided to the viewing users for each email content.

[0011] The information processing device 100 shown in FIG. 1 is connected to terminal devices 10a, 10b, and 10c of multiple users Ua, Ub, and Uc via a network N (see FIG. 2) so as to be able to communicate with each other via wired or wireless communication, and provides various information to the users Ua, Ub, and Uc. For example, the information processing device 100 is realized by one or more servers or cloud systems. Also, the information processing device 200 shown in FIG. 1 is an information processing device of a third-party user Uec (e.g., a distributor such as a store owner of an EC (Electronic Commerce) site), and is connected to the network N (see FIG. 2) so as to be able to communicate with each other via wired or wireless communication, and provides various information to the information processing device 100. For example, the information processing device 200 is realized by one or more servers or cloud systems. Hereinafter, users Ua, Ub, and so on may be referred to as user U, and terminal devices 10a, 10b, and so on may be referred to as terminal devices 10. Also, users (or browsing users) in general may be referred to as user (or browsing user) U. In addition, posted comments and input reactions may be referred to as reaction information. Furthermore, email content with comment posting and reaction input functions is, for example, email content that includes a comment posting function and a reaction input function such as a "like" button, and that allows posted comments and input reactions to be acquired as feedback from each viewing user U and shared among viewing users U. Furthermore, email content sent and received via an email distribution service provided by an existing email distribution system may be referred to as "email content without a reaction function" because the email content does not include a comment posting and reaction input function. In the embodiments, comments posted by each viewing user U and reactions input by each viewing user U via a like button or the like are described as examples, but these are merely examples and are not limiting. Other types of comments, reactions, etc. may also be used for comments, reactions, etc. For example, a survey (voting) function may be used as the reaction input function. Furthermore, a spam reporting function may be used as the reaction input function.

[0012] The terminal device 10 is a smart device such as a smartphone or tablet terminal used by a user U, and is a portable terminal device capable of communicating with any server device via a wireless communication network such as 4G (4th Generation) or LTE (Long Term Evolution). The terminal device 10 has a screen such as a liquid crystal display with a touch panel function, and accepts various operations on displayed data such as content, such as tapping, sliding, and scrolling, performed by the user U with a finger or a stylus. An operation performed on an area of ​​the screen where content is displayed may be considered 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] The information processing device 100 is an information processing device that works in conjunction with the terminal device 10 of each user U and provides API (Application Programming Interface) services for various applications (hereinafter referred to as apps) and various data to the terminal device 10 of each user U, and is realized by a computer, a cloud system, etc.

[0014] Furthermore, the information processing device 100 may 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 information processing device 100 may provide, as web services, services such as internet connection, email service, search service, SNS, 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 forecast. In practice, the information processing device 100 may cooperate with various servers that provide the above-mentioned web services and act as an intermediary for the web services or may be responsible for processing the web services.

[0015] The information processing device 100 can acquire user information about the user U. For example, the information processing device 100 acquires information about the attributes of the user U, such as the gender, age, and residential area of ​​the user U. The information processing 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.

[0016] The information processing device 100 also acquires various types of history information (log data) indicating the behavior 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 information processing device 100 acquires a location history, which is a history of the user U's location and date and time, from the terminal device 10. The information processing device 100 also acquires a search history, which is a history of search queries entered by the user U, from a search server (search engine). The information processing device 100 also acquires a browsing history, which is a history of content viewed by the user U, from a content server. The information processing device 100 also acquires a purchase history (payment history), which is a history of product purchases and payment processes by the user U, from an e-commerce server or a payment processing server. The information processing device 100 also acquires a listing history and a sales history, which are a history of the user U's listings on the marketplace, from the e-commerce server or the payment processing server. The information processing device 100 may also acquire the user U's posting history and reaction history from a posting server or SNS server that provides a word-of-mouth posting service. The various servers and the like described above may be the information processing device 100 itself. That is, the information processing device 100 may function as the various servers and the like described above.

[0017] For example, some news sites publish a summary of user U's posted comments and reactions to news articles. For example, such posted comments and reactions can be considered part of the content. Therefore, if the comments section of a news article or the total number of reactions increases, an increase in the number of page views (PV) of the corresponding news article is expected.

[0018] Therefore, the information processing apparatus 100 according to the embodiment acquires reaction information for each mail content from the users viewing the email, and provides the reaction information for each mail content to the users viewing the email as shared information.

[0019] [1-1. Delivering email content with comment posting and reaction input functions] 1, first, the information processing device 100 receives email content without a reaction function from the information processing device 200 (step S1). Here, the email content without a reaction function is email content sent and received via an email distribution service provided by an existing email distribution system, and is email content that does not have a comment posting and reaction input function.

[0020] Next, the information processing device 100 adds a comment posting and reaction input function to the mail content received from the information processing device 200 (step S2).

[0021] Next, the information processing device 100 distributes the mail content to which the comment posting and reaction input functions have been added to the terminal device 10 (step S3).

[0022] For example, on a list screen of email content on the terminal device 10, the information processing device 100 displays the number of comments posted and the number of like button inputs for email content that allows comment posting and reaction input. Email content to which a comment posting and reaction input function has been added includes, for example, email articles and comments posted or reactions input for each email article. Posted comments are, for example, comments posted by a user U on an email article, or comments posted by a user U in response to comments on an email article. Posted comments are users' opinions and impressions, and include character strings, stamps, emoticons, etc. Note that posted comments may be URLs (Uniform Resource Locators) of other content instead of or in addition to comments. Input reactions are, for example, aggregated values ​​of reactions to email articles and posted comments. Note that whether or not an email content allows comment posting and reaction input is controlled, for example, by the sender in the header information.

[0023] [1-2. Obtaining user information for comment posting users / reaction input users] Next, the information processing device 100 acquires user information (attribute information, history information, etc.) of the user U who posted the comment on the email content (step S4). The information processing device 100 identifies the user U using, for example, an ID that identifies the email content or an identifier of the terminal device 10, and acquires the user information of the user U.

[0024] Furthermore, the information processing device 100 acquires user information (attribute information, history information, etc.) of the user U who has input a reaction to the email content (step S4). The information processing device 100 identifies the user U using, for example, an ID that identifies the email content or an identifier of the terminal device 10, and acquires the user information of the user U.

[0025] [1-3. Acquiring posted comments / input reactions] Next, the information processing device 100 acquires the posted comment linked to the email content (step S5). For example, the user U operates the terminal device 10 to post a comment created for the email content from the terminal device 10 as a posted comment. For example, the user U operates the terminal device 10 to select a desired email content from a list of email contents, and the terminal device 10 links the comment created for the email content to the email content as a posted comment and transmits it to the information processing device 100.

[0026] Furthermore, the information processing device 100 acquires an input reaction linked to the email content (step S5). For example, the user U operates the terminal device 10 to input a reaction to the email content from the terminal device 10. For example, the user U operates the terminal device 10 to select a desired email content from a list of email contents, and the terminal device 10 associates the reaction input to the email content with the email content and transmits it to the information processing device 100.

[0027] The information processing device 100 can receive posted comments linked to email content and sent by each of a plurality of users including user U, and input reactions linked to email content and sent by each of a plurality of users including user U, and can store the received posted comments and input reactions in a database. For example, the information processing device 100 has a database in which a plurality of posted comments and input reactions are linked to each email content, and can acquire a plurality of posted comments and input reactions linked to email content from the database or external storage or the like.

[0028] [1-4. Update posted comments / input reactions regarding email content] Next, the information processing device 100 updates the posted comments / input reactions for the email content (step S6). For example, in the email content list, the information processing device 100 updates the number of comments and the number of high-rated reactions such as like buttons for each email content. Furthermore, in the detailed display of the email content, for example, in advertisements such as sales information, the information processing device 100 updates the content of posted comments. Furthermore, in the detailed display of the email content, for example, in advertisements such as sales information, the information processing device 100 updates the aggregated values ​​of input reactions such as "dislike," "interested," and "like." The selection buttons when inputting reactions are not limited to these, and may be different categories, or the number of categories may be increased.

[0029] For example, the information processing device 100 may notify the user U that the reaction information will be made public to users who have received the same email. The "same email" is, for example, an email in which the first 100 characters of "From," "Subject," "Date of Reception," and "Body" are the same.

[0030] [1-5. Providing email content that updates posted comments / input reactions] Next, the information processing device 100 provides the email content with the updated posted comments / input reactions to the user U (step S7). Specifically, the information processing device 100 transmits the email content with the updated posted comments / input reactions to the terminal device 10 of the user U. When the number of posted comments and the number of like button inputs reach a predetermined number within a predetermined period, the information processing device 100 may, for example, display the posted comments and input reactions in the email content list using an icon such as a hot icon. Furthermore, the information processing device 100 may display the comments of the sender in the email content with, for example, a sender comment badge. Furthermore, the information processing device 100 may rearrange the email contents in the email content list according to the status of the posted comments and input reactions.

[0031] Next, when user U views the email content displayed in the email content list and posts a comment or enters a reaction, the information processing device 100 obtains the posted comment or entered reaction linked to the email content from the terminal device 10.

[0032] [1-6. Variation (collection of targeting information)] For example, the information processing device 100 may estimate user attributes of users U who have posted comments with predetermined ratings or input reactions to email content based on the comment posting histories and reaction input histories of multiple users U, and collect the estimated user attributes as targeting information related to email delivery destinations. User attributes include user segments, user personas, etc.

[0033] At this time, the information processing device 100 may use machine learning to estimate the user attributes of the user U from the comment posting history and reaction input history of multiple users U. For example, the information processing device 100 uses the comment posting history and reaction input history of the user U as input data to generate an estimation model that outputs the user attributes of the user U. Note that multiple user attributes may be output.

[0034] Alternatively, the information processing device 100 may use machine learning to generate an estimation model that uses as input data a set of the comment posting history and reaction input history of the user U and the user attributes of the user U, and outputs an evaluation score (or an evaluation level), in order to estimate the user attributes of the user U from the comment posting history and reaction input history of the multiple users U. The evaluation score is, for example, a score that indicates an evaluation level related to the similarity or commonality of evaluations of email content in the comment posting history and reaction input history of the user U.

[0035] The information processing device 100 may, for example, use image recognition and natural language processing (NLP) to vectorize the comment posting history and reaction input history of user U, as well as the user attributes of user U, and calculate an evaluation score using the cosine similarity of each vector.

[0036] The information processing device 100 may use machine learning to generate an estimation model that uses as input data sets of comment posting histories and reaction input histories of multiple users U and evaluation scores, and outputs user attributes of users U. The information processing device 100 inputs the comment posting histories and reaction input histories of multiple users U and predetermined evaluation scores into the estimation model, and acquires user attributes of users U who are connected through, for example, the comment posting histories and reaction input histories of users U.

[0037] The machine learning method may be deep learning, a recurrent neural network (RNN), a long short-term memory (LSTM), etc. Note that these are merely examples and are not intended to be limiting.

[0038] Furthermore, the information processing device 100 may perform the above-mentioned processing by limiting it to comments posted or reactions input by a plurality of users U during a predetermined period.

[0039] In this way, the information processing device 100 acquires the reaction information of the viewing user U for each email content, and by sharing the reaction information between viewing users U, communication between viewing users U can be realized without going through other SNSs.

[0040] [2. Example of information processing system configuration] Next, the configuration of an information processing system 1 including information processing devices 100 and 200 according to an embodiment will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configuration of the information processing system 1 according to an embodiment. As shown in Fig. 2, the information processing system 1 according to an embodiment includes a terminal device 10 and information processing devices 100 and 200. These various devices are connected to each other via a network N so as to be able to communicate with each other via wired or wireless communication. The network N is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network) such as the Internet.

[0041] Furthermore, the number of devices included in the information processing system 1 shown in Fig. 2 is not limited to that shown in the figure. For example, in Fig. 2, for the sake of simplicity, only two terminal devices 10 are shown, but this is merely an example and is not limiting, and three or more devices may be included.

[0042] The terminal device 10 is an information processing device used by a user U. For example, the terminal device 10 may be a smart device such as a smartphone or a tablet terminal, a feature phone, a PC (Personal Computer), a PDA (Personal Digital Assistant), a game console or AV device with a communication function, a car navigation system, a wearable device such as a smart watch or a head-mounted display, smart glasses, etc. The terminal device 10 may also be a house / building, a car, a home appliance, an electronic device, etc. that is compatible with the Internet of Things (IOT).

[0043] In addition, the terminal device 10 can connect to a network N via a wireless communication network such as LTE (Long Term Evolution), 4G (4th Generation), or 5G (5th Generation: 5th generation mobile communication system), or via short-range wireless communication such as Bluetooth (registered trademark) or wireless LAN (Local Area Network), and communicate with the information processing devices 100 and 200.

[0044] The information processing devices 100 and 200 are, for example, computers such as PCs or blade servers, or mainframes or workstations, etc. The information processing devices 100 and 200 may be realized by cloud computing.

[0045] [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.

[0046] (Communications Department 11) The communication unit 11 is connected to a network N (see FIG. 2) by wire or wirelessly, and transmits and receives information to and from the information processing device 100 via the network N. For example, the communication unit 11 is realized by a NIC (Network Interface Card), an antenna, etc.

[0047] (Display section 12) Display unit 12 is a display device that displays various information such as position information. For example, display unit 12 is a liquid crystal display (LCD) or an organic electro-luminescent display (OLED). Display unit 12 is also a touch panel display, but is not limited to this.

[0048] (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. If the display unit 12 is a touch panel display, a part of the display unit 12 functions as the input unit 13. The input unit 13 may be a microphone that accepts voice input from the user U. The microphone may be wireless.

[0049] (Positioning unit 14) The positioning unit 14 receives signals (radio waves) transmitted from satellites 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 signals. That is, the positioning unit 14 positions the position of the terminal device 10. Note that GPS is merely an example of a GNSS (Global Navigation Satellite System).

[0050] The positioning unit 14 can also measure the position using 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 an auxiliary positioning means for position correction, etc., as described below.

[0051] (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, thereby measuring the position of the terminal device 10.

[0052] (Beacon positioning) The positioning unit 14 may also 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.

[0053] (geomagnetic positioning) The positioning unit 14 also measures the position of the terminal device 10 based on a geomagnetic pattern of a structure that has been measured in advance and a geomagnetic sensor that the terminal device 10 has.

[0054] (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, in stores, etc., or has a function of reading an RFID tag, the location where the terminal device 10 was used is recorded together with information on the payment or the like made by the terminal device 10. The positioning unit 14 may obtain such information to determine the location of the terminal device 10. Alternatively, the location may be determined by an optical sensor, an infrared sensor, or the like provided in the terminal device 10.

[0055] The positioning unit 14 may measure the position of the terminal device 10 using one or a combination of the above-mentioned positioning means, as needed.

[0056] (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 or wireless devices. In the example shown in FIG. 3 , the sensor unit 20 includes an acceleration sensor 21, a gyro sensor 22, a barometric 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.

[0057] The above-described 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.

[0058] The acceleration sensor 21 is, for example, a three-axis acceleration sensor, and detects physical movements of the terminal device 10, such as the direction of movement, speed, and acceleration of the terminal device 10. The gyro sensor 22 detects physical movements of the terminal device 10, such as tilt in three axial directions, based on the angular velocity of the terminal device 10. The air pressure sensor 23 detects, for example, the air pressure around the terminal device 10.

[0059] Since the terminal device 10 includes the acceleration sensor 21, the gyro sensor 22, the atmospheric pressure sensor 23, etc., 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.

[0060] For example, the number of steps, walking speed, and distance walked can be calculated using a pedometer that uses the acceleration sensor 21. In addition, the direction of travel, line of sight, and body tilt of the user U can be determined using the gyro sensor 22. In addition, the altitude and floor on which the user U's terminal device 10 is located can be determined from the air pressure detected by the air pressure sensor 23.

[0061] The temperature sensor 24 detects, for example, the 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.

[0062] 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, respectively, and capture images of the surroundings, thereby detecting the environment and situation around the terminal device 10. Furthermore, 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.

[0063] (control unit 30) The control unit 30 includes, for example, a microcomputer having a CPU (Central Processing Unit), ROM (Read Only Memory), RAM, input / output ports, etc., 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.

[0064] (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 to 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 information processing device 100 via the communication unit 11.

[0065] (Receiver 32) The receiving unit 32 can receive various information provided by the information processing device 100 and requests for various information from the information processing device 100 via the communication unit 11.

[0066] (Processing unit 33) The processing unit 33 controls the entire terminal device 10, including the display unit 12. For example, the processing unit 33 can output various information transmitted by the transmission unit 31 and various information received from the information processing device 100 by the reception unit 32 to the display unit 12 for display.

[0067] (Storage unit 40) The storage unit 40 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as an HDD (Hard Disk Drive), an SSD (Solid State Drive), an optical disk, etc. The storage unit 40 stores various programs, various data, etc.

[0068] [4. Configuration example of information processing device] Next, the configuration of the information processing 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 information processing device 100 according to the embodiment. As shown in Fig. 4, the information processing device 100 includes a communication unit 110, a storage unit 120, and a control unit 130.

[0069] (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 (see FIG. 2) by wire or wirelessly.

[0070] (Storage unit 120) The storage unit 120 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as an HDD, an SSD, an optical disk, etc. As shown in Fig. 4, the storage unit 120 has a user information database 121, a history information database 122, and a mail content information database 123.

[0071] (User Information Database 121) The user information database 121 stores user information about the user U. For example, the user information database 121 stores various information such as the attributes of the user U. FIG. 5 is a diagram showing an example of the user information database 121. In the example shown in FIG. 5, the user information database 121 has items such as "User ID (Identifier)," "Age," "Gender," "Home," "Workplace," and "Interests."

[0072] "User ID" refers to identification information for identifying user U. The "user ID" may be contact information for user U (telephone number, email address, etc.), or identification information for identifying user U's terminal device 10. Here, the user ID is not information that can identify an individual, such as the user's name, but may be, for example, an arbitrary character string (numeric string) that is uniquely assigned to a user who logs in or accesses the site, and may change with each access. In other words, the user ID is used to identify the estimated attribute information, etc., of the accessing user, and is information that does not allow or makes it difficult to identify an individual.

[0073] Furthermore, "age" indicates the age of user U identified by the user ID. Note that "age" may be information indicating the specific age of user U (e.g., 35 years old, etc.), or may be information indicating the generation of user U (e.g., 30s, etc.). Alternatively, "age" may be information indicating the date of birth of user U, or may be information indicating the generation of user U (e.g., born in the 1980s, etc.). Furthermore, "gender" indicates the gender of user U identified by the user ID.

[0074] Furthermore, "home" indicates the location information of the home of user U identified by the user ID. In the example shown in FIG. 5, "home" is illustrated as an abstract code such as "LC11," but it may also be latitude and longitude information, etc. Furthermore, for example, "home" may also be the name of an area or an address.

[0075] Furthermore, "workplace" indicates location information of the workplace (school in the case of a student) of user U identified by the user ID. In the example shown in FIG. 5, "workplace" is illustrated as an abstract code such as "LC12," but it may also be latitude and longitude information, etc. Furthermore, for example, "workplace" may also be the name of a region or an address.

[0076] Furthermore, "interests" indicate the interests of a user U identified by a user ID. In other words, "interests" indicate subjects in which a user U identified by a user ID is highly interested. For example, "interests" may be search queries (keywords) entered by a user U into a search engine. Note that, in the example shown in FIG. 5, one "interest" is illustrated for each user U, but there may be multiple "interests."

[0077] For example, in the example shown in FIG. 5, the age of user U identified by user ID "U1" is "20s" and the gender is "male." Furthermore, for example, the home address of user U identified by user ID "U1" is "LC11." Furthermore, for example, the workplace of user U identified by user ID "U1" is "LC12." Furthermore, for example, the user U identified by user ID "U1" is interested in "sports."

[0078] 5, abstract values ​​such as "U1", "LC11", and "LC12" are used for illustration, but "U1", "LC11", and "LC12" are assumed to store information such as specific character strings and numerical values. Below, abstract values ​​may also be illustrated in diagrams relating to other information.

[0079] The user information database 121 is not limited to the above, and may store various types of information depending on the purpose. For example, the user information database 121 may store various types of information related to the terminal device 10 of the user U. The user information database 121 may also store information related to the user U's attributes, such as demographic attributes, psychographic attributes, geographic attributes, and behavioral attributes. For example, the user information database 121 may store information such as name, family structure, hometown (hometown), occupation, job title, income, qualifications, type of residence (detached house, apartment, etc.), whether or not the user has a car, commuting time, commuting route, commuter pass section (station, line, etc.), frequently used stations (other than the nearest station to home or workplace), extracurricular activities (location, time zone, etc.), hobbies, interests, lifestyle, etc.

[0080] (History Information Database 122) The history information database 122 stores various information related to history information (log data) that indicates the behavior of the user U. Fig. 6 is a diagram showing an example of the history information database 122. In the example shown in Fig. 6, the history information database 122 has items such as "user ID," "location history," "purchase history," "search history," "browsing history," "posting history," and "reaction history."

[0081] "User ID" refers to identification information for identifying user U. Here, the user ID is not information that can identify an individual, such as the user's name, but, for example, an arbitrary character string (numeric string) that is uniquely assigned to a user who logs in or accesses the site, and may change with each access. In other words, the user ID is used to identify the accessing user's estimated attribute information, etc., and is information that does not or makes it difficult to identify an individual. Furthermore, "location history" refers to the location history, which is the history of user U's locations and movements. Furthermore, "purchase history" refers to the purchase history, which is the history of purchases made by user U. Furthermore, "search history" refers to the search history, which is the history of search queries entered by user U. Furthermore, "browsing history" refers to the browsing history, which is the history of content viewed by user U. Furthermore, "post history" refers to the posting history, which is the history of posts made by user U. Furthermore, "reaction history" refers to the reaction history, which is the history of reactions made by user U.

[0082] For example, in the example shown in Figure 6, user U, identified by user ID "U1," moved as shown in "Location History #1," purchased specific products at specific stores as shown in "Purchase History #1," searched as shown in "Search History #1," viewed content as shown in "Viewing History #1," posted as shown in "Posting History #1," and reacted as shown in "Reaction History #1."

[0083] Here, in the example shown in Figure 6, abstract values ​​such as "U1", "Location History #1", "Purchase History #1", "Search History #1", "Viewing History #1", "Posting History #1", and "Reaction History #1" are used for the illustration, but "U1", "Location History #1", "Purchase History #1", "Search History #1", "Viewing History #1", "Posting History #1", and "Reaction History #1" are assumed to store specific information such as character strings and numbers.

[0084] The history information database 122 is not limited to the above and may store various types of information depending on the purpose. For example, the history information database 122 may store the user U's usage history of a predetermined service. The history information database 122 may also store the user U's store visit history or facility visit history. The history information database 122 may also store the user U's payment history (electronic payment) using the terminal device 10.

[0085] (Email Content Information Database 123) The email content information database 123 stores various information related to email content, posted comments, and input reactions. Fig. 7 is a diagram showing an example of the email content information database 123. In the example shown in Fig. 7, the email content information database 123 has items such as "email content," "content details," "user ID," "comment posting information," and "reaction input information."

[0086] "Email content" indicates identification information for identifying the email content. In practice, this may be the title or genre of the email content (it can also be the source, theme, or category). "Content content" indicates the article of the email content or identification information for identifying the article of the email content. "User ID" indicates identification information for identifying user U. "Comment posting information" indicates comments posted on the email content or comments posted on comments included in the email content. "Reaction input information" indicates input reactions to the email content or input reactions to comments included in the email content.

[0087] For example, in the example shown in Figure 7, for email content "Delivery #1," the content is identified by "Content #1," and it shows that user U, identified by "User ID," posted a comment identified by "Comment posting information #1," and entered a reaction identified by "Reaction input information #1."

[0088] Here, in the example shown in Figure 7, abstract values ​​such as "Distribution #1," "Content #1," "Comment posting information #1," and "Reaction input information #1" are used for the illustration, but "Distribution #1," "Content #1," "Comment posting information #1," and "Reaction input information #1" are assumed to store specific information such as character strings and numbers.

[0089] The mail content information database 123 is not limited to the above, and may store various types of information depending on the purpose. For example, the mail content information database 123 may store identification information for identifying the provider (distributor) of the mail content. The mail content information database 123 may also store information related to mail content and comment trees.

[0090] (control unit 130) 4, the explanation will be continued. The control unit 130 is a controller, and 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, executing various programs (corresponding to examples of information processing programs) stored in a storage device inside the information processing 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 a distribution unit 131, an acquisition unit 132, a generation unit 133, an estimation unit 134, and a provision unit 135.

[0091] (Distribution Section 131) The delivery unit 131 delivers email content to which a comment posting and reaction input function has been added to email content that does not have a comment posting and reaction input function to the terminal device 10. The email content includes, for example, an email article and comments posted or reactions input regarding the email article.

[0092] Specifically, the delivery unit 131 delivers list information of mail contents to the terminal device 10, and then delivers mail contents corresponding to the mail selected by the user U.

[0093] In addition, the distribution unit 131 accepts comments posted and reactions entered by the user U through the email content, and registers the comments posted and reactions entered by the user U in the email content information database 123, and distributes them to the user U as email content from the next time onwards.

[0094] (Acquisition part 132) The acquisition unit 132 receives, via the communication unit 110, email content sent and received via an email distribution service provided by an existing email distribution system, which does not have the function of posting comments or entering reactions, from the information processing device 200 of a third-party user Uec (for example, a distributor such as a store owner of an e-commerce site).

[0095] The acquisition unit 132 acquires posted comments and input reactions linked to email content. For example, when a user U posts a comment or inputs a reaction related to email content from the terminal device 10, the acquisition unit 132 acquires the posted comment or input reaction linked to the email content via the communication unit 110. The acquisition unit 132 stores the comments posted in relation to the email content by each of the multiple comment posting users and the reactions input in relation to the email content by each of the multiple reaction input users in the history information database 122. The acquisition unit 132 also acquires the multiple posted comments and input reactions linked to the email content from the email content information database 123 in which the multiple posted comments and input reactions are linked to each email content, or from an external storage or the like.

[0096] Furthermore, the acquisition unit 132 acquires user information about the user U via the communication unit 110. For example, the acquisition unit 132 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 132 may acquire the identification information indicating the user U, the attribute information of the user U, and the like when registering the user U. Then, the acquisition unit 132 registers the user information in the user information database 121 of the storage unit 120.

[0097] Furthermore, the acquisition unit 132 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 132 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 the user ID or the like. Then, the acquisition unit 132 registers the various types of history information in the history information database 122 of the storage unit 120.

[0098] Furthermore, the acquisition unit 132 acquires a search query input by the user U. 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 132 acquires the search query via the communication unit 110. That is, the acquisition unit 132 acquires, via the communication unit 110, the keywords input by the user U into the search box of a search engine, website, or app.

[0099] (Generation unit 133) The generation unit 133 adds comment posting and reaction input functions to email content that is acquired by the acquisition unit 132 via the communication unit 110 and is sent and received via an email distribution service provided by an existing email distribution system, and that does not have comment posting and reaction input functions, thereby generating email content that has comment posting and reaction input functions.

[0100] (Estimation part 134) The estimation unit 134 may estimate the user attributes of users U who have posted comments with a predetermined evaluation or input reactions to email content based on the comment posting history and reaction input history of multiple users U, and collect the estimated user attributes as targeting information related to email delivery destinations. The user attributes include user segments, user personas, etc.

[0101] At this time, the estimation unit 134 may use machine learning to estimate the user attributes of the user U from the comment posting history and reaction input history of multiple users U. For example, the estimation unit 134 uses the comment posting history and reaction input history of the user U as input data to generate an estimation model that outputs the user attributes of the user U. Note that multiple user attributes may be output.

[0102] Alternatively, the estimation unit 134 may use machine learning to generate an estimation model that uses as input data a set of the user U's comment posting history and reaction input history and the user attributes of the user U, and outputs an evaluation score (or an evaluation level), in order to estimate the user attributes of the user U from the comment posting history and reaction input history of multiple users U. The evaluation score is, for example, a score that indicates an evaluation level related to the similarity or commonality of evaluations of email content in the user U's comment posting history and reaction input history.

[0103] The estimation unit 134 may, for example, use image recognition and natural language processing to vectorize the user U's comment posting history and reaction input history, as well as the user U's user attributes, and calculate the evaluation score using the cosine similarity of each vector.

[0104] The estimation unit 134 may use machine learning to generate an estimation model that uses as input data sets of comment posting histories and reaction input histories of multiple users U and evaluation scores, and outputs user attributes of users U. The estimation unit 134 inputs the comment posting histories and reaction input histories of multiple users U and predetermined evaluation scores into the estimation model, and acquires user attributes of users U who are connected through, for example, the comment posting histories and reaction input histories of users U.

[0105] The machine learning method may be deep learning, RNN, LSTM, etc. Note that these are just examples and are not limited to these examples.

[0106] Furthermore, the estimation unit 134 may perform the above process by limiting it to comments posted or reactions entered by multiple users U during a predetermined period.

[0107] (Provider 135) The providing unit 135 provides the email content with updated posted comments and input reactions to the user U. Specifically, the providing unit 135 provides the email content with updated posted comments and input reactions to the terminal device 10 of the user U via the communication unit 110.

[0108] When the number of comment posts and the number of like button inputs reach a predetermined number within a predetermined period, the providing unit 135 may provide the posted comments and input reactions, for example, in the email content list, using an icon such as a hot icon. Furthermore, the providing unit 135 may provide the comments of the sender in the email content with, for example, a sender comment badge. Furthermore, the providing unit 135 may provide the email content by rearranging it in the email content list according to the posted comments and input reactions.

[0109] [5. Processing Procedure] Next, a processing procedure by the information processing device 100 according to the embodiment will be described with reference to Fig. 8. Fig. 8 is a flowchart showing the processing procedure according to the embodiment. Note that the processing procedure shown below is repeatedly executed by the control unit 130 of the information processing device 100.

[0110] As shown in FIG. 8, the acquisition unit 132 of the information processing device 100 receives mail content without a reaction function via the communication unit 110 (step S101).

[0111] Next, the generation unit 133 of the information processing device 100 adds a comment posting and reaction input function to the mail content to generate mail content with a comment posting and reaction input function (step S102).

[0112] Next, the distribution unit 131 of the information processing device 100 distributes the email content with a comment posting and reaction input function via the communication unit 110 (step S103).

[0113] If a comment is posted or a reaction is input (step S104: Yes), the acquisition unit 132 of the information processing device 100 acquires user information of the comment posting user / reaction input user via the communication unit 110 (step S105).

[0114] Next, the acquisition unit 132 of the information processing device 100 acquires the posted comments / input reactions via the communication unit 110 (step S106).

[0115] Next, the generation unit 133 of the information processing device 100 updates the posted comments / input reactions for the email content (step S107).

[0116] Next, the providing unit 135 of the information processing device 100 provides the email content with the updated posted comment / input reaction via the communication unit 110 (step S108).

[0117] If a comment is posted or a reaction is input (step S109: Yes), the user information of the comment posting user / reaction input user is acquired via the communication unit 110 (step S105).

[0118] If there is no comment posting or reaction input (step S104: No), and the acquisition unit 132 of the information processing device 100 receives new email content via the communication unit 110 (step S110: Yes), the generation unit 133 of the information processing device 100 adds comment posting and reaction input functions to the email content, and generates email content with comment posting and reaction input functions (step S102).

[0119] [6. Modifications] The terminal device 10 and the information processing device 100 described above may be implemented in various different forms other than the above-described embodiment. Therefore, modifications of the embodiment will be described below.

[0120] In the above embodiment, some or all of the processing performed by the information processing device 100 may actually be performed 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 information processing device 100 in the above embodiment. Furthermore, in the above embodiment, the terminal device 10 cooperates with the information processing device 100, and therefore, from the perspective of the user U, it appears that the processing of the information processing device 100 is also being performed by the terminal device 10. In other words, from another perspective, it can be said that the terminal device 10 is equipped with the information processing device 100.

[0121] For example, the terminal device 10 may execute the processing of the information processing device 100 in the above embodiment as processing on an installed app. That is, the processing of the information processing device 100 in the above embodiment may be processing on an app installed on the terminal device 10. In this case, the terminal device 10 may generate an estimation model through on-device learning. Alternatively, the terminal device 10 may cooperate with the information processing device 100, provide data to the information processing device 100, and acquire an estimation model generated by the information processing device 100 through machine learning. Note that the information processing device 100 may generate an estimation model for each user attribute (segment, persona). Furthermore, the terminal device 10 may cooperate with the information processing device 100 and generate an estimation model through federated learning.

[0122] Furthermore, in the above embodiment, the email content may be a website such as a bulletin board where comments (or any other writing) can be posted, or may be SMS (Short Message Service), a messaging app, etc. Furthermore, the type (content) of the comment may be a product or service review, a questionnaire response, etc.

[0123] [7. Effects] As described above, the information processing device (terminal device 10 and information processing device 100) according to the present application includes an acquisition unit 132 that acquires reaction information for each email content from a user viewing an email, and a provision unit 135 that provides the reaction information acquired by the acquisition unit 132 to the viewing user as predetermined shared information for each email content.

[0124] The information processing device according to the present application further includes a delivery unit 131 that delivers mail content to which predetermined comment posting and reaction input functions have been added, in contrast to mail content that does not have comment posting and reaction input functions.

[0125] The acquisition unit 132 acquires predetermined comments and predetermined reactions associated with the email content.

[0126] The acquisition unit 132 acquires user information of a browsing user who posted a predetermined comment or input a predetermined reaction.

[0127] The providing unit 135 provides the email content with the updated posted comment or input reaction to the user viewing the email content.

[0128] The system further includes an estimation unit 134 that estimates the user attributes of a viewing user who posted a comment with a predetermined rating or input a reaction based on the comment posting history and reaction input history of multiple viewing users for a predetermined email content.

[0129] By performing any one or a combination of the above-described processes, the information processing device according to the present application can acquire reaction information for each email content from the users viewing the email, and share the reaction information for each email content among the viewing users.

[0130] [8. Hardware Configuration] The terminal device 10 and the information processing device 100 according to the above-described embodiments are realized by, for example, a computer 1000 configured as shown in Fig. 9. The following description will be given taking the information processing device 100 as an example. Fig. 9 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 via a bus 1090.

[0131] 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.

[0132] The primary storage device 1040 is a memory device such as a RAM (Random Access Memory) that temporarily 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 also 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 also be cloud storage (online storage), a NAS (Network Attached Storage), a file server, or the like.

[0133] 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 (High Definition Multimedia Interface), etc. 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.

[0134] 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.

[0135] 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 as an input / output I / F.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] For example, when the computer 1000 functions as the information processing 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 to call and use the functions and data of a program from another program of the other device.
