DETAILED DESCRIPTION OF THE INVENTION

[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. Overview of information processing method] First, an overview of an information processing method performed by an information processing device according to an embodiment will be described with reference to Fig. 1. Fig. 1 is an explanatory diagram showing an overview of the information processing method according to an embodiment. Note that Fig. 1 describes an example in which a recommendation service with variable accuracy is provided.

[0011] 1, the information processing system 1 includes a terminal device 10, a server device 100, and a providing terminal 200. The terminal device 10, the server device 100, and the providing terminal 200 are connected to each other via a network N (see FIG. 2) in a wired or wireless manner so as to be able to communicate with each other. In this embodiment, the terminal device 10 cooperates with the server device 100. Furthermore, the providing terminal 200 cooperates with the server device 100.

[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 (Generation (4G)) or LTE (Long Term Evolution) networks. 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 server 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] 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 the following web services: internet connection, search service, social networking 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 server 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 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) that identifies the user U.

[0016] The server 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, etc. For example, the server 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 server 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 server device 100 also acquires a browsing history, which is a history of content viewed by the user U, from a content server. The server device 100 also acquires a purchase history (payment history), which is a history of the user U's product purchases and payment processes, from an e-commerce server or a payment processing server. The server device 100 may also acquire 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 server device 100 also acquires a posting history, which is a history of the user U's posts, 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 server device 100 itself. That is, the server device 100 may function as the various servers and the like described above.

[0017] The providing terminal 200 is an information processing device used by a provider (such as an advertiser AD that distributes advertisements) of some information targeted at a user U (user). The providing terminal 200 may be a device similar to the terminal device 10 or the server device 100. In this embodiment, advertisements are described as an example of information provided to a user, but in reality, the information is not limited to advertisements and may be any information targeted at a user (information presented to a user). For example, the information is not limited to advertisements for stores, products / services, etc., but may also be some kind of recommendation information or useful information for a user, information on SNS or the like that may be of interest to the user, event announcements, etc. In other words, advertisements and advertisers are merely examples.

[0018] [1-1. Recommendation service with variable accuracy] In this embodiment, the terminal device 10 accepts a designation of the interest range from a user U (user) and provides information whose score falls within the interest range from among an unspecified number of pieces of information, such as advertisements, targeted at the user.

[0019] For example, the terminal device 10 installs an application that accepts a designation of a range of interests from a user, and selects and provides information whose scores fall within the range of the range of interests using the function of the application.

[0020] Alternatively, the terminal device 10 may accept a designation of the interest range from the user through browser settings or the like, and may provide information whose scores fall within the interest range by using a function of the browser or the like.

[0021] Alternatively, the terminal device 10 accepts a designation of the interest range from the user and notifies the server device 100. Then, the server device 100 provides information in which the score falls within the range of the interest range.

[0022] In this embodiment, as shown in FIG. 1, the server device 100 cooperates with the terminal device 10 to identify the score of an advertisement for a user (step S1).

[0023] For example, the terminal device 10 (or the server device 100) sets a score of 100 when the user inputs an advertisement that the user is "interested in," and sets a score of 0 when the user inputs an advertisement that the user is "not interested in." In this case, the terminal device 10 (or the server device 100) may determine that an advertisement that the user actually clicked or that led to a conversion (CV) is an advertisement that the user is "interested in."

[0024] Furthermore, even if the user has viewed an advertisement that the user has marked as "interesting" and subsequently purchased the advertised product, the terminal device 10 (or the server device 100) may change the score to 0, regarding the advertisement as "not interesting." This is because advertisements for products that have already been purchased are meaningless, and even if the product is purchased repeatedly, if the user likes it and purchases it for the second or subsequent time, the user is likely to purchase it without viewing the advertisement. The determination of whether the advertised product has been purchased may be made not only when a conversion is made from the advertisement, but also from the user's purchase history. Furthermore, for a product that the user has already purchased, if the user damages the product or if the time for replacement is approaching, the terminal device 10 (or the server device 100) may change the score to 100 again, regarding the advertisement as "interesting" to the user.

[0025] At this time, the terminal device 10 (or the server device 100) may be configured to always provide information with a score of 100 to the user regardless of the designation of the interest range.

[0026] Furthermore, the terminal device 10 may estimate the scores of other advertisements based on advertisements with scores of 100 or 0. In this case, the terminal device 10 may estimate the score of each advertisement by using natural language processing (NLP) based on advertisements with scores of 100 or 0. For example, the terminal device 10 may estimate the score of each advertisement from the similarity in meaning of words included in each advertisement by using Word2vec or the like.

[0027] Furthermore, the terminal device 10 may accept a score designation from the user for each advertisement (or category / genre of advertisement) presented to the user, and may treat a combination of the user (or user group), advertisement, and score as correct answer data.

[0028] Next, the server device 100 cooperates with the terminal device 10 to generate a scoring model by machine learning in order to set a score for each advertisement (step S2). For example, the scoring model is an estimation model that takes a pair of a user (or a user group) and an advertisement as input data and outputs a score.

[0029] At this time, the terminal device 10 may generate a scoring model by on-device learning. Alternatively, the terminal device 10 may cooperate with the server device 100, provide data to the server device 100, and acquire a scoring model generated by the server device 100 through machine learning. Note that the server device 100 may generate a scoring model for each user attribute or segment (user persona). Furthermore, the terminal device 10 may cooperate with the server device 100 and generate a scoring model by federated learning.

[0030] 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.

[0031] Next, the server device 100 estimates a score for each advertisement based on the scoring model (step S3). For example, the server device 100 may input a pair of a user and an advertisement into the scoring model and estimate the output score as the score of the advertisement.

[0032] Next, the terminal device 10 accepts a designation of the user U's interest range and notifies / sets it in the server device 100 (step S4).

[0033] At this time, the terminal device 10 accepts a designation of a range of interest range from the user. That is, the terminal device 10 accepts a designation of a range of scores of advertisements that are permitted to be distributed (received) from the user. For example, when accepting a designation of a range of interest range from the user, if a score of "70" is input or designated, the range of the user's interest range is set as "70 to 100."

[0034] Alternatively, the terminal device 10 may accept a designation of an upper limit and a lower limit of the score of advertisements that are permitted to be delivered, within a score range of "0 to 100," as the range of the interest range. For example, the terminal device 10 accepts a designation of a score range of "40 to 60" from the user as the range of the interest range. Note that it is also possible to designate a specific score such as "50" (50 to 50: both the upper limit and the lower limit are 50). The terminal device 10 may also notify the server device 100 of the designation of the range of the interest range accepted from the user.

[0035] Some users may desire or tolerate not only advertisements with a score of 100 that match their interests (pinpoint advertisements), but also advertisements that are slightly different from their interests. The degree of tolerance varies depending on the user. It is also possible to provide incentives to users who desire or tolerate the delivery of advertisements that are slightly different from their interests according to the level of tolerance (range of interest range). For example, advertisements with lower scores in the user's interest range can be delivered with higher incentives. This is expected to lead to the emergence of users who set the interest range lower (closer to 0).

[0036] Next, the provider terminal 200 receives, from the advertiser AD, a designation of the interest range of the user to whom the advertisement is to be distributed, and notifies / sets it in the server device 100 (step S5). The designation of the range of interest range in the provider terminal 200 by the advertiser AD may be the same as the designation of the range of interest range by the user in the terminal device 10. Note that step S4 and step S5 may be performed either first, or simultaneously.

[0037] The advertiser AD may not only want to deliver an ad with a score of 100 to users who are interested in the ad (or product), but may also want to deliver an ad to users who are not currently interested but may potentially (or in the future) become interested. In such cases, it may be possible to deliver an ad aimed at users who are not interested, rather than to users who are interested.

[0038] Next, the server device 100 distributes advertisements with scores within the specified range to the user's terminal device 10 based on the specification of the range of interest received from the user's terminal device 10 (step S6).

[0039] For example, when the server device 100 receives a designation of the interest range of a user who is the target of an advertisement from the advertiser AD, the server device 100 delivers to the user an advertisement whose score is included in the interest range of the user designated by the advertiser AD.

[0040] At this time, the server device 100 may match the interest range specified by the advertiser AD with the interest range specified by the user, and provide the user with advertisements that fall within the range of the overlapping interest ranges.

[0041] Alternatively, the terminal device 10 may provide the user with advertisements whose scores are within a specified interest range. For example, an application installed in the terminal device 10 may exclude (exclude) advertisements whose scores are outside the specified range from among advertisements delivered to the user from the server device 100, and provide the user with only advertisements whose scores are within the specified range.

[0042] Subsequently, the server device 100 notifies the advertiser AD's provider terminal 200 of the distribution status of the advertisement (step S7). For example, the server device 100 provides the advertiser AD's provider terminal 200 with statistical information on the advertisement distribution history.

[0043] In this embodiment, the terminal device 10 can deliver advertisements while allowing the user's range of interests to be variable. This can prevent a situation in which only advertisements that interest the user are presented.

[0044] In providing information such as advertisement distribution, there is a demand not only for advertisements targeted at users who are clearly interested at the time, but also for advertisements targeted at users who are not currently strongly interested but are slightly interested, or users who are not very interested but are willing to view advertisements. In order to target such user groups, it is effective not only to estimate the user group based solely on system data, but also to accept and determine the user's own range of interests. It is also important for advertisers and the like to deliver effective advertisements tailored to the range of interests of the target user group. According to this embodiment, advertisements can be delivered that will arouse strong interest in potential / future user groups.

[0045] As described above, the interest range can also be set by the advertiser. For example, the terminal device 10 displays "an advertisement at a level set by the advertiser (a relevance score with a predetermined keyword)" x "an advertisement at a level set by the user."

[0046] The interest range is set by the advertiser or the user (or both). The interest range may be an intermediate range, such as "from this value to this value" (for example, a score of 60 to 70). The interest range may also be multi-staged, with levels 2 and 3 being displayed, for example. In other words, the level of interest may be set. The interest range may also be selectable.

[0047] The interest range may be set using a slider or small, medium, or large radio buttons. Alternatively, a preference such as "I want something wider" may be used. Regarding the priority of setting the interest range, for example, if it is an advertisement, the advertiser is given priority. If it is news, the user is given priority. For users with a wide interest range and a high tolerance for advertisements, it is possible to deliver advertisements that would not normally be delivered.

[0048] The terminal device 10 may receive and distribute an input of the tolerance of an information provision target. The input of the tolerance of an information provision target may be received from the distribution source or from the distribution destination.

[0049] Furthermore, if distribution requires a fee, a wide range will increase the number of distributions, requiring a large amount of expenses (leading to a rapid loss of money). For example, the terminal device 10, in cooperation with the server device 100, may present a message to the distribution source, such as, "If you set this range, the distribution schedule (and price) will be about this," or "If you set this range, these types of users (personas) will be the distribution destinations." Furthermore, the terminal device 10, in cooperation with the server device 100, may estimate the costs required for distribution and target users on a company-by-company, product-by-product, or campaign-by-campaign basis. This will create a positive impression of the advertisement.

[0050] [2. Example of information processing system configuration] Next, a configuration of an information processing system 1 including a server device 100 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 a server device 100. These various devices are connected to each other via a network N so as to be able to communicate with each other via a wired or wireless connection. The network N is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network) such as the Internet.

[0051] 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 one terminal device 10 is shown, but this is merely an example and is not limiting, and two or more devices may be included.

[0052] 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 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).

[0053] In addition, the terminal device 10 can connect to the 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 server device 100.

[0054] 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.

[0055] [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.

[0056] (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 server device 100 via the network N. For example, the communication unit 11 is realized by a NIC (Network Interface Card), an antenna, etc.

[0057] (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.

[0058] (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, etc. The input unit 13 may be an input / output port (I / O port), a USB (Universal Serial Bus) port, etc. 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.

[0059] (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).

[0060] 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.

[0061] (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.

[0062] (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.

[0063] (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.

[0064] (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.

[0065] 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.

[0066] (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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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 terminal device 10 of the user U is located can be determined from the air pressure detected by the air pressure sensor 23.

[0071] 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.

[0072] 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.

[0073] (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.

[0074] (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 server device 100 via the communication unit 11.

[0075] (Receiver 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.

[0076] (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 transmitting unit 31 and various information received from the server device 100 by the receiving unit 32 to the display unit 12 for display.

[0077] (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.

[0078] [4. Server device configuration example] 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.

[0079] (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.

[0080] (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, a user interest level setting database 123, and a provider interest level setting database 124.

[0081] (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."

[0082] The "user ID" indicates identification information for identifying the user U. The "user ID" may be the contact information of the user U (telephone number, email address, etc.), or may be identification information for identifying the terminal device 10 of the user U.

[0083] 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), or may be information indicating the generation of user U (e.g., 30s). 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). Furthermore, "gender" indicates the gender of user U identified by the user ID.

[0084] 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.

[0085] 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.

[0086] Furthermore, "interests" indicate the interests of user U identified by the user ID. In other words, "interests" indicate subjects in which user U identified by the user ID is highly interested. For example, "interests" may be search queries (keywords) entered by user U into a search engine. In the example shown in FIG. 5, each user U is shown with one "interest," but there may be multiple "interests."

[0087] 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."

[0088] 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.

[0089] The user information database 121 may store various types of information depending on the purpose, without being limited to the above. 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 area (station, line, etc.), frequently used stations (other than the station nearest to home or workplace), extracurricular activities (location, time zone, etc.), hobbies, interests, lifestyle, etc.

[0090] (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," "search history," "browsing history," "purchase history," and "posting history."

[0091] "User ID" indicates identification information for identifying user U. "Location history" indicates the location history, which is the history of user U's location and movements. "Search history" indicates the search history, which is the history of search queries entered by user U. "Browsing history" indicates the browsing history, which is the history of content viewed by user U. "Purchase history" indicates the purchase history, which is the history of purchases made by user U. "Posting history" indicates the posting history, which is the history of posts made by user U. "Posting history" may also include questions about user U's possessions.

[0092] For example, in the example shown in Figure 6, user U, identified by user ID "U1," moved as shown in "Location History #1," searched as shown in "Search History #1," viewed content as shown in "Viewing History #1," purchased specific products at specific stores as shown in "Purchase History #1," and posted as shown in "Posting History #1."

[0093] Here, in the example shown in Figure 6, abstract values ​​such as "U1", "Location History #1", "Search History #1", "Browsing History #1", "Purchase History #1", and "Post History #1" are used for the illustration, but "U1", "Location History #1", "Search History #1", "Browsing History #1", "Purchase History #1", and "Post History #1" are assumed to store specific information such as character strings and numbers.

[0094] 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.

[0095] (User Interest Setting Database 123) The user interest level setting database 123 stores various information related to the setting of the interest level specified by the user U (user). Fig. 7 is a diagram showing an example of the user interest level setting database 123. In the example shown in Fig. 7, the user interest level setting database 123 has items such as "user ID", "information category", "user specified upper limit value", and "user specified lower limit value".

[0096] The "user ID" indicates identification information for identifying the user U. The "information category" indicates the category of information provided to the user U. For example, the "information category" indicates the category of advertisements, etc., targeted for distribution to the user U.

[0097] In addition, the "user-specified upper limit value" indicates the upper limit value of the interest level specified by the user U for the information in the set category. If the "user-specified upper limit value" is not set (if not set), the initial state (default) is the upper limit value "100". In addition, the "user-specified lower limit value" indicates the lower limit value of the interest level specified by the user U for the information in the set category. If the "user-specified lower limit value" is not set (if not set), the initial state (default) is the lower limit value "0".

[0098] For example, the "user-specified upper limit" and the "user-specified lower limit" indicate the range of scores of advertisements that the user U is willing to receive (be delivered). In practice, a "user-specified level" may be set instead of the "user-specified upper limit" and the "user-specified lower limit." The "user-specified level" indicates the level of interest specified by the user U for the information in the set category.

[0099] Here, if no "information category" is set at all (if not set), the "user-specified upper limit value" and "user-specified lower limit value" indicate the upper and lower limit values ​​of the interest level specified by user U for information in all categories. In this case, for information in categories other than those set in the "information category", the upper and lower limit values ​​of the interest level specified by user U for information in all categories are applied. Furthermore, for information in a category set in the "information category", the upper and lower limit values ​​of the interest level specified by user U for information in that category take precedence over the upper and lower limit values ​​of the interest level specified by user U for information in all categories.

[0100] 7, user U identified by user ID "U1" has set (specified) an upper limit of "60" and a lower limit of "40" as the interest level for information that falls under "information category #1." In other words, user U identified by user ID "U1" allows the delivery of advertisements that fall under "information category #1" and have a score within the range of an upper limit of "60" and a lower limit of "40."

[0101] Here, in the example shown in Figure 7, abstract values ​​such as "U1" and "Category #1" are used for illustration, but "U1" and "Category #1" are assumed to store information such as specific character strings and numerical values.

[0102] The user interest setting database 123 may store various information according to the purpose, not limited to the above. For example, the user interest setting database 123 may store information on the attributes, segments, etc. of the user U.

[0103] (Provided by interest level setting database 124) The provider interest level setting database 124 stores various information related to the setting of the interest level of target users who are to receive information (to whom advertisements are delivered) specified by a provider (such as an advertiser). Fig. 8 is a diagram showing an example of the provider interest level setting database 124. In the example shown in Fig. 8, the provider interest level setting database 124 has items such as "user ID," "information category," "provider-specified upper limit value," "provider-specified lower limit value," and "target user attribute."

[0104] "Provider ID" indicates identification information for identifying the information provider (advertiser, etc.). "Information Category" indicates the category of information provided to the target user. For example, "Information Category" indicates the category of advertisements, etc., targeted for distribution to the target user.

[0105] In addition, the "provider-specified upper limit value" indicates the upper limit value of the interest level of the target user specified by the provider for the information of the set category. If the "provider-specified upper limit value" is not set (if not set), the initial state (default) is the upper limit value "100". In addition, the "provider-specified lower limit value" indicates the lower limit value of the interest level of the target user specified by the provider for the information of the set category. If the "provider-specified lower limit value" is not set (if not set), the initial state (default) is the lower limit value "0".

[0106] For example, the "provider-specified upper limit value" and the "provider-specified lower limit value" indicate the range of the advertisement score, and indicate that information (advertisement) is provided (distributed) to a user U whose range at least partially overlaps with the range of the "user-specified upper limit value" and the "user-specified lower limit value" shown in FIG. 7 as a target user. Note that, in practice, a "provider-specified level" may be set instead of the "provider-specified upper limit value" and the "provider-specified lower limit value." The "provider-specified level" indicates the level of interest of the target user specified by the provider for information of the set category.

[0107] Additionally, "target user attributes" indicates the attributes and segments (user personas) of the target users who are to receive information from the set category (targets for advertisement delivery). If "target user attributes" are not set (if not set), all users will be targeted.

[0108] For example, in the example shown in Figure 8, the provider identified by the provider ID "AD1" specifies a range for the interest level for information that falls under "Information Category #1" that overlaps with the range indicated by the upper limit value "60" and lower limit value "40" specified by the provider, and indicates that information (advertisement) will be provided (distributed) to user U who falls under the target user attribute "Attribute #1".

[0109] Here, in the example shown in Figure 8, abstract values ​​such as "AD1", "Category #1", and "Attribute #1" are used for the illustration, but "AD1", "Category #1", and "Attribute #1" are assumed to store specific information such as character strings and numerical values.

[0110] The provider degree of interest setting database 124 may store various information according to the purpose, not limited to the above. For example, the provider degree of interest setting database 124 may store detailed information about the provider. The provider degree of interest setting database 124 may also store information about the period (deadline) for providing information (advertisement distribution) in the set category.

[0111] (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 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 reception unit 132, an estimation unit 133, a collation unit 134, and a provision unit 135.

[0112] (Acquisition part 131) The acquisition unit 131 acquires a search query input by a 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 131 acquires the search query via the communication unit 110. That is, the acquisition unit 131 acquires, via the communication unit 110, the keywords input by the user U into the search box of a search engine, website, or app.

[0113] Furthermore, the acquisition unit 131 acquires user information about 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, etc. 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, etc. when registering the user U. Then, the acquisition unit 131 registers the user information in the user information database 121 of the storage unit 120.

[0114] 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 the user ID or the like. Then, the acquisition unit 131 registers the various types of history information in the history information database 122 of the storage unit 120.

[0115] (Reception Department 132) The receiving unit 132 receives a designation of the interest range of the user U (user) via the communication unit 110. For example, the receiving unit 132 receives a designation of the interest range of the user U from the terminal device 10 of the user U. The receiving unit 132 also receives a designation of the interest range of the user U to be provided with information (advertisements, etc.) from the provider terminal 200 of the advertiser AD (information provider). Note that the information is not limited to advertisements, etc., and is arbitrary.

[0116] At this time, the reception unit 132 may receive a specification of the range of interests of user U from user U's terminal device 10 via the communication unit 110, and may also receive a specification of the range of interests of user U to whom information is to be provided from the advertiser AD provider terminal 200.

[0117] Furthermore, the receiving unit 132 receives, as the designation of the interest range, the designation of any numerical value between 0 and 100. For example, the receiving unit 132 may receive, as the designation of the interest range, the designation of an upper limit value and a lower limit value between 0 and 100. That is, the receiving unit 132 can receive, as the designation of the interest range, the designation of an intermediate range that does not include 0 and 100.

[0118] Alternatively, the receiving unit 132 may receive, as the designation of the interest range, a designation of a level indicating the degree of interest. For example, the receiving unit 132 may receive, as the designation of the interest range, a designation of any level such as three levels or five levels.

[0119] Furthermore, the receiving unit 132 receives, from the user U via the communication unit 110, a designation of a score for information (which may be a category of information, etc.) viewed by the user U. For example, the receiving unit 132 may receive a designation of a score of "100" for information that the user U is interested in, and a designation of a score of "0" for information that the user U is not interested in. Alternatively, the receiving unit 132 may receive a designation of an individual score for each piece of information that the user U has viewed.

[0120] (Estimation part 133) The estimation unit 133 estimates the score of the information to be provided from the information viewed by the user U (information presented to the user U). For example, the estimation unit 133 generates a score estimation model using, as learning data, a pair of the user U (which may be an attribute or segment of the user U), the information viewed by the user U (which may be a category of information, etc.), and a score specified by the user U. Then, the estimation unit 133 may input the pair of the user U and the information into the score estimation model and obtain the output score as an estimation result.

[0121] Alternatively, the estimation unit 133 may identify information that the user U has viewed that is of interest (information with a score of "100") and information that the user U has no interest in (information with a score of "0"), and estimate the score of each piece of information using techniques such as natural language processing.

[0122] (Collation unit 134) The collation unit 134 compares the range of interest range specified by the user U with the range of interest range specified by the information provider, and determines the overlapping range of the range of interest range specified by the user U and the range of interest range specified by the information provider. If the range of interest range specified by the user U overlaps with the range of interest range specified by the information provider, the collation unit 134 determines that the user U is a target user for information provision (advertising delivery). In other words, the collation unit 134 determines the target user for information provision (advertising delivery) based on the overlapping range of interest ranges specified by both.

[0123] At this time, the matching unit 134 may determine that the user U is a target user for information provision (advertising distribution) if the ranges of interest ranges specified by both parties overlap even partially. Alternatively, the matching unit 134 may determine that the user U is a target user for information provision (advertising distribution) only if the range of interest range specified by the user U is completely included in the range of interest range specified by the information provider. Conversely, the matching unit 134 may determine that the user U is a target user for information provision (advertising distribution) only if the range of interest range specified by the user U is completely included in the range of interest range specified by the information provider.

[0124] (Provider 135) The providing unit 135 provides information whose score falls within the range of the interest range from among an unspecified number of pieces of information targeted at the user U based on the designation of the interest range to the terminal device 10 of the user U via the communication unit 110. For example, the providing unit 135 provides information whose score falls within the range of the interest range based on the interest range designated by the user U to the terminal device 10 of the user U. Furthermore, the providing unit 135 provides information whose score falls within the range of the interest range based on the range of the interest range designated by the information provider to the terminal device 10 of the user U who is the information recipient.

[0125] At this time, the providing unit 135 may provide, via the communication unit 110, to the terminal device 10 of the user U, information whose score is within a range that overlaps the range of interest range specified by the user U and the range of interest range specified by the information provider.

[0126] Furthermore, for example, the providing unit 135 notifies the provider terminal 200 of the information provider (advertiser, etc.) of the information provision status (advertisement distribution status) via the communication unit 110. For example, the providing unit 135 provides statistical information on the information provision history (advertisement distribution history) to the provider terminal 200 of the information provider (advertiser, etc.) via the communication unit 110.

[0127] [5. Processing Procedure] Next, a processing procedure by the server device 100 according to the embodiment will be described with reference to Fig. 9. Fig. 9 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 server device 100.

[0128] The receiving unit 132 of the server device 100 receives, via the communication unit 110, from the terminal device 10 of the user U, a designated score for information (which may be a category of information, etc.) viewed by the user U (step S101).

[0129] Next, the estimation unit 133 of the server device 100 performs machine learning based on the scores of the information viewed by the user U, and generates an estimation model of the scores (step S102).

[0130] Next, the estimation unit 133 of the server device 100 estimates a score for each piece of information to be provided using the score estimation model (step S103).

[0131] Next, the receiving unit 132 of the server device 100 receives a designation of the interest range of the user U from the terminal device 10 of the user U via the communication unit 110 (step S104).

[0132] Next, the reception unit 132 of the server device 100 receives, via the communication unit 110, from the source terminal 200 of the information provider (advertiser, etc.), a specification of the range of interests of the user U (target user) to whom the information will be provided (the target of the advertisement delivery) (step S105).

[0133] Next, the matching unit 134 of the server device 100 compares the range of interest range specified by the user U with the range of interest range specified by the information provider, and if the range of interest range specified by the user U overlaps (at least partially) with the range of interest range specified by the information provider, it determines that the user U is a target user for information provision (advertising delivery) (step S106).

[0134] Next, the providing unit 135 of the server device 100 provides, via the communication unit 110, to the terminal device 10 of the user U, information whose score falls within the range of the interest range, from among an unspecified number of pieces of information targeted at the user U, based on the specified interest range (step S107).

[0135] Next, the providing unit 135 of the server device 100 notifies the providing source terminal 200 of the information providing source (advertiser, etc.) of the information providing status (advertisement distribution status) via the communication unit 110 (step S108).

[0136] [6. Modifications] The terminal device 10 and the server device 100 described above may be implemented in various different forms other than the above embodiment. Therefore, modifications of the embodiment will be described below.

[0137] 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. Furthermore, in the above embodiment, the terminal device 10 is linked to the server device 100, and therefore, from the perspective of the user U, it appears that the processing of the server device 100 is also being executed by the terminal device 10. In other words, from another perspective, the terminal device 10 can also be said to be equipped with the server device 100.

[0138] Furthermore, in the above embodiment, the terminal device 10 may directly or indirectly (via the server device 100) notify the advertiser AD of the designation of the interest range received from the user. For example, the terminal device 10 may notify the advertiser AD of the designation of the interest range received from the user. Then, the advertiser AD may directly or indirectly (via the server device 100) deliver to the user an advertisement included in the interest range designated by the user.

[0139] [7. Effects] As described above, the information processing device (terminal device 10 and server device 100) according to the present application is characterized by including a receiving unit 132 that receives a specification of a user's interest range, and a providing unit 135 that provides information whose score falls within the range of the interest range from among an unspecified number of pieces of information targeted at the user based on the specification of the interest range.

[0140] For example, the receiving unit 132 receives a designation of the user's interest range from the user, and the providing unit 135 provides the user with information whose score falls within the range of the interest range.

[0141] Alternatively, the receiving unit 132 receives a specification of the range of interests of the user to whom the information is to be provided from the information provider, and the providing unit 135 provides information whose score is within the range of the range of interests to the user to whom the information is to be provided.

[0142] At this time, the receiving unit 132 may receive a designation of the user's interest range from the user and also receive a designation of the interest range of the user to whom information is to be provided from the information provider, and the providing unit 135 may provide the user with information whose score is included in a range that overlaps the range of the interest range designated by the user and the range of the interest range designated by the information provider.

[0143] The receiving unit 132 receives a designation of any numerical value between 0 and 100 as the designation of the interest range.

[0144] The receiving unit 132 also receives designation of an upper limit value and a lower limit value between 0 and 100 as a designation of the interest range.

[0145] Alternatively, the receiving unit 132 receives, as the specification of the interest range, a specification of a level indicating the degree of interest.

[0146] The information processing device according to the present application further includes an estimation unit 133 that estimates the score of the information to be provided from the information viewed by the user.

[0147] By performing any one or a combination of the above-described processes, the information processing device according to the present application can provide a recommendation service with variable accuracy.

[0148] [8. Hardware Configuration] The terminal device 10 and the server device 100 according to the above-described embodiments are realized by a computer 1000 having a configuration as shown in Fig. 10, for example. The following description will be given taking the server device 100 as an example. Fig. 10 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.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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 to call and use the functions and data of a program from another program of the other device.
