Description

[Technical Field]

[0001] The present invention relates to an information processing device, an information processing method, and an information processing program. [Background technology]

[0002] A technology has been disclosed for delivering image information related to the contents of an electronic article to a user terminal (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-072949 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is room for improvement in the above-mentioned conventional technology. For example, when delivering news to a user terminal, the above-mentioned conventional technology can display news on the user terminal in a way that attracts the user's interest without delivering video. However, there is a possibility that the news will be conveyed from a biased perspective if there is only one article (one item) for one event. Therefore, it is necessary to make it possible to grasp an event not only from the perspective of the article provided by the CP (Contents Provider), which is the source (sender), but also from the perspectives of each of the other articles related to the same event.

[0005] The present application has been made in view of the above, and aims to realize a function for displaying events by line of sight. [Means for solving the problem]

[0006] The information processing device according to the present application is characterized by comprising an acquisition unit that acquires various articles, a classification unit that classifies the articles according to the event that they are the subject of, an identification unit that identifies sentences told from each perspective in each article relating to the same event, an insertion unit that inserts a perspective title indicating a different perspective from the perspective in a part of a sentence told from a certain perspective in a base article, and a display control unit that, when the perspective title is operated, displays sentences told from a different perspective in other articles relating to the same event. [Effects of the Invention]

[0007] According to one aspect of the embodiment, a function for displaying events by line of sight can be realized. [Brief explanation of the drawings]

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. These various devices are connected to each other via a network N in a wired or wireless manner so as to be able to communicate with each other. This 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, 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 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. Event display function by perspective] In this embodiment, the server device 100 cooperates with the terminal device 10 of the user U via the network N to perform an integrated display of news from different perspectives (different perspectives) on the same event. For example, if another article contains a sentence written from a different perspective than the base article (target article), the server device 100 displays a perspective title (which may be a perspective icon) indicating that perspective alongside the sentence written from that perspective in the base article.

[0020] At this time, the server device 100 processes only articles for which permission has been obtained from the right holder of the article (the company or user who posted it). For example, a contract regarding the use of the article may be concluded in advance with the right holder of the article (or their representative). Alternatively, when generating content using another article, the server device 100 inquires with the poster of that article, and only if permission to use the article is granted is the content using that article provided and published to the outside world. In other words, this prevents unauthorized use of the article.

[0021] Examples of perspectives include the perspective of the person involved, the perspective of a related party, the perspective of an eyewitness, the perspective of a local resident, the perspective of an expert, the perspective of a reporter on the scene, etc. In other words, different perspectives exist for the same event depending on the position or stance of the sender or speaker. However, in reality, perspectives are not limited to these examples.

[0022] The events to be processed are major events with multiple articles (at least 3-4 or more). If this embodiment is applied to all events and small events with only a few articles, the number of articles to be processed may become enormous. It would also be a heavy burden for the viewer (user U) to compare the differences in perspective for every article. Furthermore, if there is only one article, the perspective contained in that article is all that is processed.

[0023] Furthermore, articles about the same event are not limited to articles from different sources (senders), but may be articles from the same source. Furthermore, if a viewer (user U) is following articles about the same event, the article may be the one immediately preceding the one they are currently viewing. Regardless of whether the source is the same or different, the server device 100 retrieves texts from other articles about the same event that are written from different perspectives. For example, even if the event and source are the same, the perspectives may differ depending on the reporters who wrote the articles or the people interviewed.

[0024] The server device 100 identifies the points based on each perspective in each article reporting the same event. Then, the server device 100 displays a perspective title indicating a different perspective at a location in the base article where there is a sentence written from the CP's perspective of the article, and when the perspective title is operated (tapped, clicked, etc.), the server device 100 displays the sentence written from the different perspective below the perspective title.

[0025] The server device 100 may implement the above mechanism using AI (Artificial Intelligence) such as GPT (Generative Pre-trained Transformer). GPT is a text generation AI and a language model capable of generating sentences using natural language processing.

[0026] For example, as shown in Fig. 1, the server device 100 collects articles provided by various sources (senders) (step S1). At this time, the server device 100 may collectively post the articles as topics in a topic list.

[0027] Next, the server device 100 identifies, for each article, the event covered in the article (the event that is the subject of the article) (step S2).

[0028] Next, the server device 100 classifies the articles by the events covered in the articles (step S3). For example, the server device 100 classifies each article based on the events covered in the article, and groups articles that report on the same event (articles that have a common event as their subject).

[0029] Next, the server device 100 identifies sentences written from each perspective in each article reporting the same event (step S4). Note that, in practice, the server device 100 may identify (estimate) parts in each article that are presumed to be sentences written from each perspective.

[0030] Next, the server device 100 inserts a perspective title (which may be a perspective icon) indicating a different perspective into (or near) a location in the base article where a sentence written from the perspective of the article is located (step S5). At this time, the server device 100 uses AI such as GPT to generate perspective titles corresponding to the perspectives of each sentence written in each article related to the same event. Note that the base article may be an article currently being accessed and viewed by the user U, who is a reader, an article listed in a topics list, or each collected article. In other words, the server device 100 may control the display of the perspective title when the user U views the article, or may insert the perspective title in advance as part of the article. The server device 100 may also insert a perspective title for each perspective. In other words, multiple perspective titles may be inserted.

[0031] Next, when the viewer user U operates (tap, click, etc.) the perspective title, the server device 100 displays the sentence written from the different perspective below the perspective title (step S6). At this time, the server device 100 may display information about the original article (source) in which the sentence written from the different perspective is written, or a link to the original article. For example, the server device 100 may be configured so that when a portion of the sentence written from the different perspective is tapped, the user moves to the page of the original article in which the sentence written from the different perspective is written.

[0032] In this way, the server device 100 displays sentences that are not included in the base article but are written from different perspectives in other articles. That is, the server device 100 displays the differences between the base article and other articles for sentences written from each perspective as sentences written from different perspectives.

[0033] Furthermore, the server device 100 may identify (estimate) for each clause in the same article the parts of the subject event (or sub-events or related events derived from the event) that are described from different perspectives. For example, the server device 100 may use an AI such as GPT to estimate the source of each perspective (whose perspective it is), and if the estimated sources of perspective are different, generate a perspective title that indicates whose perspective it is, such as the perspective of a local resident.

[0034] The server device 100 then provides the portion for each line of sight together with a line of sight title. At this time, the server device 100 may insert the line of sight title before the portion for each line of sight. Alternatively, the server device 100 may display only the line of sight title at the location of the portion for each line of sight, and provide the portion for each line of sight in a collapsed display so that the portion for each line of sight is displayed when the line of sight title is tapped.

[0035] In practice, the server device 100 may display the above-mentioned parts for each perspective and their perspective titles only if there are no perspectives in the other articles that are different from the base article, or if there are insufficient perspectives in the other articles.

[0036] The server device 100 may also summarize and display sentences written from different perspectives. The server device 100 may also summarize the content of each perspective, or may summarize articles by perspective.

[0037] Note that news articles are just one example. In reality, the information may be content or comments posted on social media, Q&A sites, life advice sites, specialized sites, etc.

[0038] [3. Example of terminal device configuration] Next, the configuration of the terminal device 10 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configuration of the terminal device 10 according to the embodiment. As shown in Fig. 2, 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.

[0039] (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.

[0040] (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.

[0041] (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.

[0042] (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).

[0043] 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.

[0044] (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.

[0045] (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.

[0046] (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.

[0047] (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.

[0048] 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.

[0049] (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. 2 , 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] (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.

[0057] (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.

[0058] (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.

[0059] (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.

[0060] (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.

[0061] [4. Server device configuration example] Next, the configuration of the server device 100 according to the embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the configuration of the server device 100 according to the embodiment. As shown in Fig. 3, the server device 100 includes a communication unit 110, a storage unit 120, and a control unit 130.

[0062] (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.

[0063] (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.

[0064] (control unit 130) 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. 3 , the control unit 130 has an acquisition unit 131, a classification unit 132, an identification unit 133, a generation unit 134, an insertion unit 135, and a display control unit 136.

[0065] (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.

[0066] 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.

[0067] 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.

[0068] Furthermore, the acquisition unit 131 acquires various articles via the communication unit 110. For example, the acquisition unit 131 acquires articles provided by various distribution sources (senders) via the communication unit 110.

[0069] (Classification section 132) The classification unit 132 classifies articles by the event that is the subject of the article. For example, the classification unit 132 classifies each article based on the event that is covered in the article, and groups articles that report on the same event (articles that have a common event as the subject of the article).

[0070] (Specific Section 133) The identification unit 133 identifies sentences written from each perspective in each article related to the same event. At this time, the identification unit 133 may use AI such as GPT to identify each perspective and the sentences written from that perspective. Furthermore, the identification unit 133 targets an event for which there are a predetermined number of articles (for example, 3 to 4 or more), and identifies sentences written from each perspective in each article related to the event. Furthermore, the identification unit 133 identifies the parts written from each perspective for each clause in each article related to the same event. Note that the identification unit 133 may be an estimation unit that estimates each perspective and the sentences written from that perspective, or may be an extraction unit that extracts sentences written from each perspective in each article.

[0071] (Generation unit 134) The generation unit 134 generates a perspective title according to the perspective of each sentence spoken in each article about the same event. At this time, the generation unit 134 may generate a perspective title by using AI such as GPT to estimate the perspective of each sentence spoken in each article about the same event. Note that, if information about the perspective (sender, speaker, etc.) is described in each article, the generation unit 134 generates a perspective title based on the information about the perspective.

[0072] (insertion part 135) The insertion unit 135 inserts a perspective title indicating a different perspective from the perspective of the article into a portion of a sentence spoken from that perspective in the base article. The insertion unit 135 also inserts a perspective title indicating the perspective for each perspective. In practice, the insertion unit 135 may be included in the display control unit 136.

[0073] (Display control unit 136) When the perspective title is operated, the display control unit 136 displays sentences written from different perspectives in other articles related to the same event. The display control unit 136 may also display summaries of sentences written from different perspectives. Furthermore, the display control unit 136 may display, together with sentences written from different perspectives, information indicating other articles that are the source of the sentences, as sources. Alternatively, the display control unit 136 may display, together with sentences written from different perspectives, links to other articles that are the source of the sentences.

[0074] [5. Processing Procedure] Next, a processing procedure by the server device 100 according to the embodiment will be described with reference to Fig. 4. Fig. 4 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.

[0075] For example, as shown in FIG. 4, the acquisition unit 131 of the server device 100 acquires articles provided from various distribution sources (senders) via the communication unit 110 (step S101).

[0076] Next, the classification unit 132 of the server device 100 classifies the articles by the event that serves as the subject, and groups articles that have a common event as the subject (step S102).

[0077] Next, the identifying unit 133 of the server device 100 identifies sentences written from each perspective in each article about the same event (step S103).

[0078] Next, the generating unit 134 of the server device 100 generates perspective titles according to the perspectives of the sentences spoken in the articles relating to the same event (step S104).

[0079] Next, the inserting unit 135 of the server device 100 inserts a perspective title indicating a different perspective from the given perspective into a portion of a sentence in the base article that is spoken from that perspective (step S105).

[0080] Next, the display control unit 136 of the server device 100 displays the base article on the terminal device 10 of the user U via the communication unit 110, and when the perspective title is operated by the viewer, user U, displays the sentence spoken from the perspective indicated by the perspective title below the perspective title (step S106).

[0081] [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.

[0082] 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.

[0083] In the above embodiment, the server device 100 may use optical character recognition / reader (OCR) and natural language processing (NLP) to vectorize the text of the base article and the text of the other articles, and determine whether they are about the same event based on the cosine similarity of the vectors. If they are about the same event, the server device 100 may classify them into the same group as articles about the same event.

[0084] In the above embodiment, the server device 100 may vectorize each sentence in each article about the same event using optical character recognition (OCR) and natural language processing (NLP), and determine whether the sentences are written from the same perspective based on the cosine similarity of each vector. If the sentences are not written from the same perspective, the server device 100 may determine that the sentences are written from different perspectives.

[0085] Furthermore, in the above embodiment, the server device 100 may display a perspective title (which may be a perspective icon) indicating the perspective at a location (or in the vicinity) of a sentence written from the perspective of the base article, and when the perspective title is operated (tapped, clicked, etc.) by the user U who is a viewer, the server device 100 may display sentences of other articles written from the same perspective as the perspective title below the perspective title. In other words, the server device 100 may display, within the base article, sentences of other articles written from the same perspective as the perspective of the article.

[0086] [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 an acquisition unit that acquires various articles, a classification unit 132 that classifies the articles according to the event that is the subject of the article, an identification unit 133 that identifies sentences written from each perspective in each article relating to the same event, an insertion unit 135 that inserts a perspective title indicating a different perspective from the perspective in a part of a sentence written from a certain perspective in a base article, and a display control unit 136 that, when the perspective title is operated, displays sentences written from a different perspective in other articles relating to the same event.

[0087] The information processing device according to the present application further includes a generating unit 134 that generates perspective titles according to the perspectives of the sentences spoken in the articles relating to the same event.

[0088] The identification unit 133 targets an event for which there are a predetermined number of articles or more, and identifies sentences written from each perspective in each article related to the event.

[0089] The identifying unit 133 identifies the parts written from each perspective for each clause in each article relating to the same event.

[0090] The inserting unit 135 inserts a line-of-sight title indicating the line of sight for each line of sight.

[0091] The display control unit 136 summarizes and displays sentences spoken from different perspectives.

[0092] The display control unit 136 displays, together with the sentences written from different perspectives, information indicating other articles from which the sentences originate as sources.

[0093] The display control unit 136 displays the sentences written from different perspectives together with links to other articles that are the sources of the sentences.

[0094] By performing any one or a combination of the above-described processes, the information processing device according to the present application can realize a function of displaying events by line of sight.

[0095] [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. 5, for example. The following description will be given taking the server device 100 as an example. Fig. 5 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.
