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

[0011] Terminal device 10 is an information processing device used by a user U. For example, terminal device 10 may be a smart device such as a smartphone or tablet terminal, a desktop or notebook (laptop) type PC (Personal Computer), a mobile phone such as a feature phone (Gala-ke or Gala-ho), a PDA (Personal Digital Assistant), a game console or AV device with communication functions, an information appliance or digital appliance, a car navigation system, a wearable device such as a smart watch, a head-mounted display, or smart glasses. Terminal device 10 may also be a house or building, a car, a home appliance, an electronic device, or the like that is compatible with the Internet of Things (IOT).

[0012] In this embodiment, the terminal device 10 is a smart device such as a smartphone or tablet 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 LTE (Long Term Evolution), 4G (4th Generation), or 5G (5th Generation: fifth generation mobile communication system), Bluetooth (registered trademark), or wireless LAN. 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 or a laptop PC.

[0013] 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.

[0014] In this embodiment, 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.

[0015] The server device 100 may also be an information processing device that provides some kind of online service to the terminal device 10 of each user U. For example, the server device 100 may provide the following online services: internet connection, search service, chat service, interactive service using voice, images, videos, etc., 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, weather forecast, etc. In practice, the server device 100 may cooperate with various servers that provide the above-mentioned online services and act as an intermediary for the online services or may be responsible for processing the online services.

[0016] The server device 100 can acquire user information about the user U. For example, the server device 100 acquires, as the user information, information (attribute information) about the attributes of the user U, such as the gender, age, and residential area of ​​the user U. The server device 100 can also acquire information about the attributes of the user U, such as demographic attributes, psychographic attributes, geographic attributes, and behavioral attributes. The server device 100 may also acquire, as the user information, a segment to which the user U belongs in the marketing field or a persona (personality). The server device 100 then stores and manages the information (attribute information) about the attributes of the user U together with identification information (such as a user ID) that identifies the user U.

[0017] 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.

[0018] Furthermore, the number of devices included in the information processing system 1 shown in Fig. 1 is not limited to that shown in the figure. For example, in Fig. 1, for the sake of simplicity, only one terminal device 10 is shown, but this is merely an example and is not limiting, and two or more devices may be included.

[0019] [2. Visualizing changes in events from the past to the present] In this embodiment, when a user U (user) views an article about an event on a news site / app, the server device 100 displays a summary of the article content from past to present together with a summary of the public reaction at that time (public mood and temperature), either automatically or in response to an operation by the user U. In this way, the server device 100 displays the summary of the article content and the summary of the public reaction at that time in chronological order from past to present for a certain event, and visualizes and presents the transition of how the article content and the public reaction at that time have each changed.

[0020] The server device 100 realizes the above mechanism using AI (Artificial Intelligence) such as GPT (Generative Pre-trained Transformer). GPT is a text generation AI, and is a language model capable of generating sentences using natural language processing. However, AI such as GPT is merely an example. In reality, a similar technology may also be used.

[0021] For example, as shown in Fig. 1, the server device 100 collects articles and comments posted to the articles for each event that is the subject of news (step S1). For example, the server device 100 collects articles published about the same event during the same period (within a certain period) and comments posted to the articles. In practice, the server device 100 may select a representative article, such as the most viewed article or the article with the most comments posted, from among the articles published about the same event during the same period (within a certain period).

[0022] Next, the server device 100 generates a summary of the article content and a summary of the comment content for each event for each period (predetermined period) (step S2). The period may be on a yearly or monthly basis. For example, the server device 100 aggregates and analyzes the content of the collected articles for each event for each period, and generates a summary of the article content. The server device 100 also aggregates and analyzes the content of comments posted on the collected articles, and generates a summary of the comment content. That is, the server device 100 generates a summary of the content of articles published about the same event during the same period (within a certain period), and a summary of the content of the posted comments. In practice, the server device 100 may generate a summary of the content of a representative article among articles published about the same event during the same period (within a certain period), and a summary of the content of the comments posted on the article.

[0023] In addition, even if articles and comments were collected within the same period, if the content of the later article differs significantly from the content of the earlier article after a certain point in time, or if the content of the comments posted on the article begins to shift to opinions that are different from those that had been mainstream up until then, the server device 100 may divide the period and treat the articles and comments as being from different periods.

[0024] Next, the server device 100 accumulates a pair of a time, a summary of the article content, and a summary of the comment content for each event (step S3). For example, the server device 100 may create and store a new data table in the database by linking the time when the article was published, the summary of the article content, and the summary of the comment content. Alternatively, the server device 100 may have an AI such as GPT learn pairs of the time when the article was published, the summary of the article content, and the summary of the comment content.

[0025] Next, the server device 100 accepts a designation of an event from the user U (step S4). For example, when the user U inputs a search query to search for a certain event within the app, the server device 100 receives the search query indicating the event input by the user U from the terminal device 10 of the user U via the network N. Then, the server device 100 searches for summaries of article contents and summaries of comment contents related to the event based on the search query.

[0026] Next, the server device 100 chronologically arranges the article summaries and comment summaries related to the event specified by the user U based on the publication dates of the articles, compares the contents of the preceding and following pairs of the chronologically arranged article summaries and comment summaries, and determines whether there is a difference between the preceding and following contents (step S5). For example, the server device 100 calculates the degree of discrepancy between the contents of the preceding and following article summaries and comment summaries, and determines that there is a difference between the contents of the preceding and following articles if the degree of discrepancy is equal to or greater than a threshold. Alternatively, the server device 100 calculates the degree of similarity between the contents of the preceding and following article summaries and comment summaries, and determines that there is no difference between the contents of the preceding and following articles if the degree of similarity is equal to or greater than a threshold. The degree of discrepancy and similarity of the contents may be calculated using techniques such as natural language processing (NLP). For example, the server device 100 may vectorize the preceding and following contents and calculate the degree of discrepancy and similarity from the cosine similarity of multidimensional vectors. However, the above is merely an example, and in reality, the present invention is not limited to the above example.

[0027] If there is no difference between the preceding and following contents, the server device 100 selects only one of the compared preceding and following contents as the display target (step S6). That is, if an article summary and a comment summary with similar content follow each other when arranged chronologically, the server device 100 displays only the first or latest article summary and comment summary. Then, the server device 100 displays the article summary and comment summary with different content next.

[0028] Next, the server device 100 presents to the user U a summary of the article contents and a summary of the comment contents arranged in chronological order for the event specified by the user U (step S7). For example, the server device 100 causes the terminal device 10 of the user U to display the summary of the article contents and the summary of the comment contents arranged in chronological order via the network N.

[0029] At this time, the server device 100 may display the summaries of the article contents and the summaries of the comment contents arranged in chronological order in a manner that visually indicates differences (divergences) between the preceding and following contents. For example, the server device 100 may badge, underline, bold, color the text in a different color from the other text, add a background color or pattern, blink, or make the text wobble (move in small increments) on the text that differs from the preceding and following contents.

[0030] In the above explanation, the server device 100 aggregates articles and comments and generates a summary of the article content and a summary of the comment content before accepting the designation of an event from the user U. However, in reality, when accepting the designation of an event from the user U, the server device 100 may aggregate past and latest articles and comments related to the event and generate a summary of the article content and a summary of the comment content, respectively. In other words, when accepting the designation of an event from the user U, the server device 100 may generate a summary of the article content and a summary of the comment content in real time and display them in chronological order.

[0031] Furthermore, in aggregating articles and comments for each event, the server device 100 may divide the period from the oldest to the newest for each event into fixed periods and aggregate the articles and comments thereon for each fixed period. Alternatively, the server device 100 may divide the period from the oldest to the newest for each event at the timing when a major change occurs in the content of the article (or the content of the comment), and aggregate the articles and comments thereon for each divided period.

[0032] Furthermore, in the above description, the server device 100 displays the article summary and the comment summary side by side in chronological order, but in reality, only one of them may be displayed. For example, the server device 100 may first display the article summary in chronological order, and then, when a user clicks a link (or button) called "Public Reaction" displayed along with the article summary, display summaries of the comments related to the article in chronological order. Alternatively, the server device 100 may display only the comment summaries in chronological order from the beginning.

[0033] The following describes how to visualize the transition of public reaction by displaying a summary of the comment content in chronological order, with reference to Figure 2. Figure 2 is a diagram showing an image of the visualization of the transition of public reaction. The public reaction refers to the public's feelings that can be sensed from comments on news, etc., such as the atmosphere and sentiment of the public.

[0034] For example, as shown in Figure 2 (A), if the event specified by user U is the "slush fund problem," the first public reaction is, "The ruling party's slush fund problem has been uncovered, and with the tax payment issue also involved, there has been a huge uproar and harsh public opinion." The next public reaction is, "A bill to amend the regulatory law is being considered, but there is a large gap between the content of the bill and the public's opinion, leading to even harsher public opinion." The next public reaction is, "Distrust of the ruling party is growing, and with the ruling party having suffered consecutive losses in the most recent elections and weakening, there is growing public interest in a dissolution of the Diet and a general election." In this way, we can see that public reactions are changing.

[0035] Furthermore, as shown in Figure 2 (B), when the event specified by user U is "real estate investment," the first public reaction is, "Past real estate price crashes and the discovery of fraud involving certain banks have created a negative image and comments about real estate investment." The next public reaction is, "Due to negative interest rates, mortgage rates have reached an all-time low, condominium sales are booming, and people are split into those who want to buy and those who want to rent, and their opinions are being actively expressed." The next public reaction is, "The weak yen is also related, and investment money from overseas is affecting real estate in urban areas. As condominium prices rise, real estate investment is becoming a trend, and opinions from purchasers are becoming more active." In this way, we can see that public reactions are changing.

[0036] In this manner, in this embodiment, news and comments related to a predetermined event are collected. Furthermore, for each predetermined period, a summary is generated of the news distributed during that period and the comments posted in response to that news. Then, when a user researches the event, the generated summary is used to generate content showing the changes in public sentiment and mood (social atmosphere) regarding the event, and the content is provided to the user.

[0037] [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 according to the embodiment. 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.

[0038] (Communications Department 11) The communication unit 11 is connected to the network N by wire or wirelessly, and transmits and receives information to and from the server device 100 via the network N. For example, the communication unit 11 is realized by a NIC (Network Interface Card), an antenna, etc.

[0039] (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.

[0040] (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.

[0041] (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).

[0042] 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.

[0043] (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.

[0044] (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.

[0045] (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.

[0046] (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.

[0047] 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.

[0048] (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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] (control unit 30) The control unit 30 includes, for example, a microcomputer having a CPU (Central Processing Unit) or MPU (Micro Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), 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.

[0056] (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.

[0057] (Receiving unit 32) The receiving unit 32 can receive various types of information provided by the server device 100 and requests for various types of information from the server device 100 via the communication unit 11.

[0058] (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.

[0059] (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.

[0060] [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.

[0061] (Communication unit 110) The communication unit 110 is realized by, for example, a network interface card (NIC), etc. The communication unit 110 is connected to a network N by wire or wirelessly.

[0062] (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. The storage unit 120 may store attribute information and history information (log data) of the user U together with identification information (such as a user ID) indicating the user U.

[0063] (control unit 130) The control unit 130 is a controller, and is realized by, for example, a central processing unit (CPU), a micro processing unit (MPU), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or the like, by 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 collection unit 132, a reception unit 133, a generation unit 134, an identification unit 135, and a presentation unit 136.

[0064] (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.

[0065] 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 the user U is registered. Then, the acquisition unit 131 stores the user information in the storage unit 120.

[0066] 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 stores the various types of history information in the storage unit 120.

[0067] (Collection Department 132) The collection unit 132 collects comments posted on articles related to a predetermined event. For example, the collection unit 132 collects articles related to a predetermined event and comments posted on the articles. The collection unit 132 collects, for each event, comments posted on articles related to the event. The collection unit 132 may be included in the acquisition unit 131 described above. In other words, the collection unit 132 may be one of the functions of the acquisition unit 131 described above.

[0068] (Reception Department 133) The reception unit 133 receives the designation of an event from the user U. For example, the reception unit 133 receives information indicating the event designated by the user U from the terminal device 10 of the user U via the communication unit 110. The reception unit 133 may be included in the acquisition unit 131 described above. In other words, the reception unit 133 may be one of the functions of the acquisition unit 131 described above.

[0069] (Generation unit 134) The generation unit 134 generates a summary of the content of the collected comments for each predetermined period. For example, the generation unit 134 generates a summary of the content of the collected articles and a summary of the content of the comments for each predetermined period. Note that the generation unit 134 generates a summary of the content of the comments for each event for each predetermined period.

[0070] At this time, when the generation unit 134 receives the designation of an event from the user U, the generation unit 134 may divide the comments posted to the article about the designated event into predetermined time periods and generate summaries of the contents of the comments.

[0071] (Specific Section 135) The identification unit 135 identifies a portion where the summaries of the content of the comments for each period are displaced from the preceding and following contents when the summaries of the content of the comments for each period are arranged in chronological order. The identification unit 135 also calculates the degree of displacedness between the preceding and following contents when the summaries of the content of the comments for each period are arranged in chronological order, and determines that the preceding and following contents are displaced if the degree of displacedness is equal to or greater than a threshold.

[0072] The identification unit 135 may perform similar processing not only on the content of comments but also on the content of articles. For example, the identification unit 135 may identify a deviation between the previous and next content when summaries of the content of articles for each period are arranged in chronological order. Furthermore, the identification unit 135 may calculate the degree of deviation between the previous and next content when summaries of the content of articles for each period are arranged in chronological order, and determine that the previous and next content is deviation if the degree of deviation is equal to or greater than a threshold.

[0073] (Presentation part 136) The presentation unit 136 displays summaries of the content of comments for each period in chronological order on the terminal device 10 of the user U via the communication unit 110, thereby presenting content that visualizes the public's reaction to a predetermined event and the changes in the social atmosphere. For example, the presentation unit 136 displays summaries of the content of articles for each period and summaries of the content of comments in chronological order, respectively, thereby presenting content that visualizes the changes in the content of articles related to the predetermined event and the public's reaction to the predetermined event and the changes in the social atmosphere. Note that the presentation unit 136 may be a display control unit that controls the screen display of the terminal device 10 of the user U via an API or the like.

[0074] In addition, when an arbitrary event is specified, the presentation unit 136 displays summaries of the content of comments for each period for the specified event in chronological order, and presents content that visualizes the public's reaction to the event and the changes in the social atmosphere.

[0075] For example, when the presentation unit 136 receives a designation of a specific event from a user U, it displays summaries of the content of comments for each period about the specific event in chronological order, and presents content that visualizes the public's reaction to the specific event and the changes in the social atmosphere.

[0076] Furthermore, when displaying summaries of the content of comments for each period in chronological order, the presentation unit 136 displays in a display manner that allows a visibly recognizable portion of the summary of the content of the comment, where the summaries deviate from the content before and after the comment. Note that when displaying summaries of the content of articles for each period in chronological order, the presentation unit 136 may display in a display manner that allows a visibly recognizable portion of the summary of the content of the article, where the summaries deviate from the content before and after the article.

[0077] Furthermore, when summaries of the content of comments for each period are arranged in chronological order, if there is no change in the content before and after the comment, the presentation unit 136 displays a summary of the content of either the previous or next comment.

[0078] [5. Processing Procedure] Next, a processing procedure by the server device 100 according to the embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart showing the processing procedure according to the embodiment. Note that the processing procedure shown below is repeatedly executed by the control unit 130 of the server device 100.

[0079] For example, as shown in FIG. 5, the collection unit 132 of the server device 100 collects, for each event, articles relating to the event and comments posted to the articles (step S101).

[0080] Next, the generating unit 134 of the server device 100 generates a summary of the content of the collected articles and a summary of the content of the comments for each event for each predetermined period (step S102).

[0081] Next, the receiving unit 133 of the server device 100 receives information indicating the event designated by the user U from the terminal device 10 of the user U via the communication unit 110 (step S103).

[0082] Next, the identifying unit 135 of the server device 100 identifies, for the event specified by the user U, a portion where the summaries of the content of the comments for each period are deviated from the preceding and following content when they are arranged in chronological order (step S104).

[0083] Next, the presentation unit 136 of the server device 100 displays, via the communication unit 110, on the terminal device 10 of the user U, summaries of the contents of articles and summaries of the contents of comments for each period for the event specified by the user U, arranged in chronological order, and also displays in a visible manner any parts of the summary of the contents of the comments that deviate from the contents before and after, thereby presenting content that visualizes the changes in the contents of articles related to the specified event and the changes in public reaction and social atmosphere to the specified event (step S105).

[0084] [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.

[0085] 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 (or an application running on 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 cooperates with 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.

[0086] Furthermore, in the above embodiment, an example is described in which news articles or the like related to an event and comments posted to those articles are used. However, in reality, the present invention is not limited to news articles or the like. For example, instead of news articles or the like, content that can be displayed in a browser, app, or the like and that relates to a specific theme, article, topic, or the like may be targeted. For example, the content may be a social networking site, a video / streaming site, a Q&A site, a specialized field site, a life advice site, or the like. The server device 100 may collect comments posted to any of these pieces of content related to a certain event. In this case, the server device 100 may classify the content by type and collect content related to a certain event and comments posted to that content, respectively. The server device 100 may then generate summaries of the collected content and summaries of the comments, respectively, at predetermined intervals.

[0087] In the above embodiment, the server device 100 may aggregate and analyze multiple pieces of content related to the same event that were published around the same time, not limited to news articles, and generate a summary of the overall content of the multiple pieces of content. In this case, the server device 100 may also aggregate and analyze the content of comments posted on each of the multiple pieces of content, and generate a summary of the overall content of each comment.

[0088] [7. Effects] As described above, the information processing device (terminal device 10 and server device 100) according to the present application is characterized by comprising a collection unit 132 that collects comments posted on articles relating to a predetermined event, a generation unit 134 that generates summaries of the collected comments for each predetermined period, and a presentation unit 136 that displays the summaries of the comments for each period in chronological order and presents content that visualizes the public's reaction to the predetermined event and the changes in the social atmosphere.

[0089] This makes it possible to clearly show the public's reaction to a given event and the changes in social atmosphere over time.

[0090] The collection unit 132 also collects articles related to a predetermined event and comments posted to the articles. The generation unit 134 generates summaries of the collected article content and summaries of the comment content for each predetermined period. The presentation unit 136 displays the article content summaries and comment content summaries for each period in chronological order, and presents content that visualizes the changes in the content of articles related to the predetermined event and the changes in public reactions and social atmosphere regarding the predetermined event.

[0091] This makes it possible to clearly show changes in the content of articles about a given event over time, as well as changes in public reactions and social atmosphere.

[0092] The information processing device according to the present application further includes a receiving unit 133 that receives the designation of an event from the user U. When the presentation unit 136 receives the designation of a predetermined event from the user U, it displays summaries of the contents of comments for each period about the predetermined event in chronological order, and presents content that visualizes the public's reaction to the predetermined event and the transition of the social atmosphere.

[0093] This allows a user to find out how the public has reacted to a given event and how the social atmosphere has changed over time, and to be presented with information on how the public has reacted to the event and how the social atmosphere has changed over time.

[0094] The collection unit 132 collects, for each event, comments posted to articles related to the event. The generation unit 134 generates a summary of the content of the comments for each predetermined period for each event. When an arbitrary event is designated, the presentation unit 136 displays summaries of the content of the comments for each period for the designated event in chronological order, and presents content that visualizes the public's reaction to the event and the changes in the social atmosphere.

[0095] This makes it possible to clearly show the public's reaction and changes in social atmosphere over time to any given event among a variety of events.

[0096] Alternatively, the information processing device according to the present application further includes a receiving unit 133 that receives a designation of an event from a user U. When the designation of an event is received from the user U, the generating unit 134 divides comments posted to articles related to the designated event into predetermined time periods and generates summaries of the content of the comments. The presenting unit 136 displays the summaries of the content of the comments for each period in chronological order, and presents content that visualizes the public's reaction to the designated event and the transition of the social atmosphere.

[0097] This makes it possible to present the public's reactions to events desired by the user and the transition of social atmosphere.

[0098] The information processing device according to the present application further includes an identifying unit 135 that identifies a portion of the summary of the content of the comments for each period that is deviated from the preceding and following content when the summary of the content of the comments for each period is arranged in chronological order. When the presenting unit 136 displays the summaries of the content of the comments arranged in chronological order, the presenting unit 136 displays the portion of the summary of the content of the comments that is deviated from the preceding and following content in a visually recognizable display mode.

[0099] This makes it possible to clearly identify the changes in public reaction and social atmosphere over time, and to understand how public reaction and social atmosphere changed.

[0100] The identification unit 135 calculates the degree of deviation between the preceding and following contents when summaries of the content of the comments for each period are arranged in chronological order, and determines that the preceding and following contents are deviated if the degree of deviation is equal to or greater than a threshold value.

[0101] This allows us to quantitatively understand changes in public reactions and social atmosphere regarding events over time.

[0102] If there is no change in the content before and after a comment when summaries of the content of the comments for each period are arranged in chronological order, the presentation unit 136 displays a summary of the content of either the previous or next comment.

[0103] This makes it possible to avoid displaying the same unchanging content, and to select and display only summaries of comments that reflect the public's reaction to an event over time or when changes in the social atmosphere occur.

[0104] By performing any one or a combination of the above-described processes, the information processing device according to the present application can clearly indicate the change in public reaction and social atmosphere with respect to a predetermined event over time.

[0105] [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. 6, for example. The following description will be given taking the server device 100 as an example. Fig. 6 is a diagram showing an example of a hardware configuration. The computer 1000 is connected to an output device 1010 and an input device 1020, and has a configuration in which a calculation device 1030, a primary storage device 1040, a secondary storage device 1050, an output I / F (Interface) 1060, an input I / F 1070, and a network I / F 1080 are connected via a bus 1090.

[0106] 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), a GPU (Graphics Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.
