Description

Technical Field

[0001] The present disclosure relates to an information processing apparatus, a program, and an information processing method. Background Art

[0002] In recent years, there has been an information distribution service that automatically extracts and distributes new original information from published information (hereinafter referred to as "original information") such as public information including weather information or earthquake information, information on websites, and posts on social networking services (hereinafter simply referred to as "SNS"). Information distributed to users in the information distribution service (hereinafter referred to as "distribution information") is information generated based on the extracted original information, and for example, is the original information itself or information obtained by processing the original information. For example, Patent Document 1 describes a search device that extracts post data satisfying a specific condition from post data transmitted from each communication terminal located in a specified area and a plurality of areas around the specified area, specifies an area selected based on the number of extracted post data, and acquires post data transmitted from a communication terminal located in the specified area. Post data satisfying the specific condition is, for example, post data related to a specific event such as an incident. Prior Art Documents Patent Documents

[0004] However, traditionally, there has been no distinction made between user-submitted posts; all posts are treated uniformly. As a result, even when some users are considered to provide useful, or valuable, or reliable, posts, it has been impossible to distinguish their posts from those of other users, making it difficult to distribute information more appropriately.

[0005] This disclosure was made to solve the above-mentioned problems and aims to provide an information processing device, information processing system, and program that enable more appropriate information distribution than conventional methods. [Means for solving the problem]

[0006] The information processing device relating to this disclosure comprises a posting information acquisition unit that acquires posting information which is first posting information posted by a first user and second posting information posted by a second user other than the first user; a distribution information generation unit that generates distribution information based on the posting information acquired by the posting information acquisition unit; and a distribution information transmission unit that transmits the distribution information generated by the distribution information generation unit to a user terminal, wherein the distribution information transmission unit is characterized in that the range of user terminals to which distribution information based on the first posting information is transmitted is narrower than the range of user terminals to which distribution information based on the second posting information is transmitted. [Effects of the Invention]

[0007] According to this disclosure, the configuration described above enables more appropriate information distribution compared to the previous method. [Brief explanation of the drawing]

[Figure 12] This flowchart shows a specific example of the operation of step ST104 by the information processing device according to Embodiment 1. [Figure 13] This figure shows a specific example of the operation of step ST104 by the information processing device according to Embodiment 1. [Modes for carrying out the invention]

[0009] The embodiments will be described in detail below with reference to the drawings. Embodiment 1. Figure 1 is a block diagram showing the configuration of the information processing system 1 according to Embodiment 1. In Figure 1, the information processing system 1 is a system in which an information processing device 2 and a plurality of user terminals 3 are connected via a network. The network is a telecommunications line including the Internet 4. The information processing system 1 is used to provide information distribution services.

[0010] Information processing device 2 is a server that provides information distribution services. Information processing device 2 obtains posted information from user terminal 3 via the network, generates distribution information based on the posted information, and sends the distribution information to user terminal 3.

[0011] The information distribution service provided by the information processing device 2 may be a single information distribution service or multiple information distribution services (a first information distribution service and a second information distribution service). For example, the first information distribution service is an information distribution service used by the information processing device 2 when it acquires posted information from the user terminal 3 and when it transmits distribution information based on said posted information to the user terminal 3. Also, for example, the second information distribution service is an information distribution service used by the information processing device 2 when it distributes distribution information based on the posted information acquired via the first information distribution service.

[0012] User terminal 3 is a terminal used by users who utilize the information distribution service provided by the information processing device 2. User terminal 3 is a terminal device capable of communicating with at least the information processing device 2 via a network, and is, for example, a smartphone, tablet, or PC (Personal Computer). A dedicated application for using the information distribution service (hereinafter referred to as the "dedicated service application") is installed in the user terminal 3. Alternatively, the information distribution service may be provided to the user terminal 3 in the form of SaaS (Software as a Service). When the information distribution service is provided in the form of SaaS, the service application that provides the information distribution service is executed by the information processing apparatus 2, and the user terminal 3 can receive the provision of the information distribution service on a web browser without installing a dedicated service application.

[0013] Note that the user may be any of various organizations or individuals. The term "organization" includes various for-profit or non-profit organizations such as incorporated enterprises, individual enterprises, and administrative organizations, and the term "individual" includes ordinary people as various natural persons.

[0014] The information processing apparatus 2 will be described in more detail. As shown in FIG. 1, the information processing apparatus 2 includes a communication unit 21, an arithmetic unit 22, and a storage unit 23. The communication unit 21 communicates with the user terminal 3 via a network. For example, the communication unit 21 is capable of communicating via a network with the user terminal 3 that enables mobile communication according to a communication scheme such as LTE, 3G, 4G, or 5G. The arithmetic unit 22 controls the overall operation of the information processing apparatus 2. The arithmetic unit 22 includes a user authentication unit 221, a posted information acquisition unit 222, a non-disclosure determination unit 223, a distribution information generation unit 224, and a distribution information transmission unit 225. Each function of the user authentication unit 221, the posted information acquisition unit 222, the non-disclosure determination unit 223, the distribution information generation unit 224, and the distribution information transmission unit 225 is realized by the arithmetic unit 22 executing an information processing application. The storage unit 23 stores, for example, information processing applications and information used in the calculations of the calculation unit 22. The storage unit 23 stores, for example, posting information and distribution information as information used in the calculations. The storage unit 23 is a storage device provided by the computer that functions as an information processing device 2, and includes storage such as an HDD (Hard Disk Drive) or SSD (Solid State Drive), or the memory 103 shown in Figure 2, which will be described later.

[0015] Figure 2 is a block diagram showing the hardware configuration that realizes the functions of the information processing device 2. For example, the information processing device 2 has a communication interface 100, an input / output interface 101, a processor 102, and memory 103 as its hardware configuration. The functions of the information processing device 2, namely the user authentication unit 221, the non-disclosure determination unit 223, the posting information acquisition unit 222, the distribution information generation unit 224, and the distribution information transmission unit 225, are realized by executing an information processing application on this hardware configuration.

[0016] The communication interface 100 outputs data received from an external user terminal 3 via the network to the processor 102, and the processor 102 transmits the generated data to the user terminal 3 via the network. The processor 102 reads and writes data to the storage unit 23 in Figure 1 via the input / output interface 101.

[0017] The programs constituting the information processing applications for realizing the functions of the user authentication unit 221, the post information acquisition unit 222, the non-disclosure determination unit 223, the distribution information generation unit 224, and the distribution information transmission unit 225 are stored in the storage unit 23. The processor 102 reads the programs stored in the storage unit 23 via the input / output interface 101 and loads them into the memory 103, and then executes the programs loaded into the memory 103. In this way, the processor 102 realizes the functions of the user authentication unit 221, the post information acquisition unit 222, the non-disclosure determination unit 223, the distribution information generation unit 224, and the distribution information transmission unit 225. The memory 103 is, for example, RAM (Random Access Memory).

[0018] The user authentication unit 221 determines whether the user making the post is the first user. In this case, the user authentication unit 221 determines whether the user is the first user based on the information entered by the user using the user terminal 3. If the user authentication unit 221 determines that the user is not the first user, it determines that the user is the second user.

[0019] The first user is a user who is considered to provide useful posting information, that is, posting information of high value or reliability. One or more of these first users are pre-configured for the information processing device 2. Examples of these primary users include public institutions, designated public institutions, designated local public institutions, partner companies, social welfare councils, NPOs, or disaster volunteer management organizations.

[0020] This first user is, for example, a user whose identity has been verified in advance by the provider of the information processing device 2, ensuring the reliability of the posted information, and who has been assigned attribute information such as a first user flag by the provider. In contrast, the second user is, for example, a user who posted from a website, whose identity has not been verified in advance by the provider of the information processing device 2, and whose reliability of the posted information is not ensured.

[0021] For example, the storage unit 23 of the information processing device 2 stores one or more pieces of information (first user information) that indicate the first user. The first user information is, for example, a string indicating the first user's unique account name or a string indicating the first user's unique ID. In this case, the user authentication unit 221 compares the information entered by the user using the user terminal 3 with the first user information stored in the storage unit 23. If there is first user information that matches the information entered by the user, the unit determines that the user using the user terminal 3 is the first user.

[0022] Furthermore, if the first user is an organization, the first user information may be provided to only one organization, or it may be provided to multiple organizations, such as with license IDs.

[0023] Figure 1 shows the case where the user authentication unit 221 is provided on the information processing device 2. However, the user authentication unit 221 is not an essential component of the information processing device 2, and it is not necessary for the user authentication unit 221 to be provided in the information processing device 2.

[0024] The posting information acquisition unit 222 acquires posting information submitted by users using the user terminal 3. The posting information acquired by this posting information acquisition unit 222 consists of first posting information and second posting information. First posting information is posting information submitted by the first user. Second posting information is posting information submitted by the second user.

[0025] The post information acquired by the post information acquisition unit 222 consists of at least one of either text or an image. The image is at least one of either a still image or a moving image. The moving image may also be a live image.

[0026] Furthermore, the posting information obtained by the posting information acquisition unit 222 includes, for example, event information. Event information is information about an event. This event information includes, for example, information indicating the type of event.

[0027] For example, the types of events include fire, earthquake, flooding, typhoon, heavy rain, heavy snow, tornado, lightning, landslide, traffic accident, traffic congestion, road closure, road construction, road closure, disruptions to public transport such as delays or suspensions, power outages, water outages, gas supply interruptions, accidents in factories, business closures of specific companies, building collapses, mass infections, system failures, strikes, crimes, or riots.

[0028] Furthermore, the event information may include information indicating the location where the event occurred. Information indicating the location where an event occurred may, for example, be information indicating the geographical location where the event occurred, information indicating the geographical range where the event occurred, or information indicating the geographical interval where the event occurred. Location information indicating a geographical location may, for example, be information indicating a point represented by latitude and longitude, or it may be information indicating an address or residence. Geographic location information may include, for example, information indicating a set of three or more points, shown as an area enclosed by lines connecting these points, or it may be information indicating a regional name such as a city, town, prefecture, or country. Geographic location information for a segment includes at least information indicating the start and end points of the segment, and may also include information indicating the route between the start and end points.

[0029] Furthermore, the event information may include information indicating the time when the event occurred. Information indicating the time the event occurred may, for example, be the time the image was taken if the post includes an image, or it may be the time the post was made. If the image is a video, the time the image was taken may be, for example, the time the video was recorded.

[0030] Furthermore, the posting information acquired by the posting information acquisition unit 222 may include information that identifies the user who made the posting (user identification information). User identification information may include, for example, the name, address, or a string indicating the user's unique account name or a string indicating the user's unique ID, which the user has registered with the information processing device 2 in order to use the information distribution service.

[0031] The posting information acquisition unit 222 acquires posting information from user terminal 3 used by a user determined to be the first user by the user authentication unit 221 as first posting information. The posting information acquisition unit 222 also acquires posting information from user terminal 3 used by a user not determined to be the first user by the user authentication unit 221 (i.e., the second user) as second posting information.

[0032] Even if the information processing device 2 is not equipped with a user authentication unit 221, the post information acquisition unit 222 can determine whether the acquired post information is the first post information or the second post information by another method. For example, if the first post information includes user identification information, the post information acquisition unit 222 can determine whether the post information is the first post information or the second post information from the user identification information included in the post information.

[0033] Furthermore, the posting information acquisition unit 222 may acquire not only posting information but also publicly available information. Examples of publicly available information include information on websites, posting information on social media, or other publicly available information. In this case, for example, the posting information acquisition unit 222 acquires publicly available information provided by various servers via the network, such as a web server that provides a website, an SNS server that provides an SNS, and a public information server that provides public information. Examples of SNS include X (formerly Twitter®), Instagram®, TikTok®, YouTube®, and Facebook®.

[0034] The non-disclosure determination unit 223 determines whether there is a request for non-disclosure of the first posted information, and if it determines that there is a request for non-disclosure of the first posted information, it further determines the level of non-disclosure. In this case, the non-disclosure determination unit 223 determines the level of non-disclosure by determining whether there are requests for non-disclosure at multiple stages for the first posted information. More specifically, for example, the non-disclosure determination unit 223 determines the level of non-disclosure by determining whether there is a request for non-disclosure during user authentication and whether there is a request for non-disclosure when posting the first posted information. This level of non-disclosure refers to the range of user terminals 3 that can access the first posted information, and multiple levels can be set. For example, if the level of non-disclosure is high (for example, if non-disclosure is requested during user authentication), the range of user terminals 3 that can access the first posted information will be narrower compared to when the level of non-disclosure is low (for example, if non-disclosure is requested when posting the first posted information).

[0035] This non-disclosure determination process by the non-disclosure determination unit 223 is performed when the first post information is obtained by the post information acquisition unit 222. Furthermore, there is no request for non-disclosure regarding the second submitted information.

[0036] In this case, for example, the storage unit 23 of the information processing device 2 stores in advance information indicating whether the first posted information by the first user should be kept confidential or made public, as attribute information of the information identifying the first user (first user information). This attribute information can be set and changed by a higher-ranking user, such as an administrator or person in charge among the first users. Then, when a user who posts the first post information performs user authentication using user terminal 3, the user authentication unit 221 determines that the user is the first user. The non-disclosure determination unit 223 then reads the attribute information of the authenticated first user (first user information) from the storage unit 23 to determine whether or not non-disclosure was requested during user authentication for the first post information. Hereafter, non-disclosure requested during user authentication may be referred to as authentication-time non-disclosure. This authentication-time non-disclosure continues as long as the user is authenticated, and all first post information posted while the user is authenticated will be treated as authentication-time non-disclosure.

[0037] Next, the first user who posts the first information input uses the user terminal 3 to input information to the information processing device 2 indicating whether or not to keep the first information confidential at the time of posting. The non-disclosure determination unit 223 then determines from the information input by the first user via the user terminal 3 whether or not a request for non-disclosure was made for the posting of the first information. In the following, the non-disclosure requested at the time of posting of the first information input may be referred to as non-disclosure at the time of posting. This non-disclosure at the time of posting is set each time the first information input is posted. For example, as shown in Figure 3, the first user can input information to the information processing device 2 indicating whether or not to keep information confidential when posting, using a screen displayed on the user terminal 3 for selecting whether or not to keep information confidential when posting (Confidentiality Selection Screen for Posting). In the example in Figure 3, first, as shown in Figure 3A, a screen for posting the first post information (posting screen) is displayed on the user terminal 3. The posting screen shown in Figure 3A displays an image input field 301, a text input field 302, and a post button 303. The image input field 301 is used by the first user when inputting an image. The text input field 302 is used by the first user when inputting text. The information entered using at least one of the image input field 301 and the text input field 302 becomes the first post information. The post button 303 is a button that the first user selects when posting the first post information. Then, when the user selects the post button 303 on the posting screen shown in Figure 3A, a screen for selecting whether or not to disclose information at the time of posting (the posting non-disclosure requirement selection screen) is displayed on the user terminal 3, as shown in Figure 3B. On the posting non-disclosure requirement selection screen shown in Figure 3B, two selection buttons 304 and 305 are displayed. Selection button 304 is the button that the first user selects when making the first post information public. Selection button 305 is the button that the first user selects when making the first post information non-disclosure at the time of posting. In this case, the non-disclosure determination unit 223 can determine whether or not there is a request for non-disclosure at the time of posting for the first post information by determining which of the selection buttons 304 and 305 on the posting non-disclosure requirement selection screen was selected. Then, when the user selects either of the selection buttons 304 or 305 on the non-disclosure selection screen shown in Figure 3B, a screen indicating the completion of the posting of the first post information and the completion of the non-disclosure setting (completion screen) is displayed on the user terminal 3, as shown in Figure 3C. On the completion screen shown in Figure 3C, the completion button 306 is displayed. The completion button 306 is the button that the first user selects when they want to exit the screen.Furthermore, if there is a request for non-disclosure at the time of authentication for the first posted information, the first user who posts the first posted information cannot set whether or not to request non-disclosure at the time of posting. In other words, they will proceed directly from the posting screen shown in Figure 3A to the completion screen shown in Figure 3C without going through the non-disclosure selection screen shown in Figure 3B.

[0038] In this way, the information processing device 2 can appropriately disclose or withhold the first posted information by, for example, determining whether a non-disclosure request has been set by a higher-level user such as an administrator or person in charge during user authentication, and determining whether a non-disclosure request has been set by the poster during posting.

[0039] In addition, the above example shows a case where the non-disclosure determination unit 223 determines the level of non-disclosure by determining whether there are multiple stages of non-disclosure requests for the first posted information. However, the non-disclosure determination unit 223 may also determine the level of non-disclosure by acquiring information indicating the level of non-disclosure.

[0040] For example, the first user who posts the first information input inputs information into the information processing device 2 using the user terminal 3, before posting the first information input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input input and if there is a request for non-disclosure For example, as shown in Figure 4, the first user can input information to the information processing device 2 indicating whether or not to keep the first posted information confidential, using a screen (non-disclosure requirement selection screen) displayed on the user terminal 3. The non-disclosure requirement selection screen shown in Figure 4 displays three selection buttons 401 to 403. Selection button 401 is selected by the first user when they want to make the first posted information public. Selection button 402 is selected by the first user when they want to keep the first posted information confidential from anyone other than themselves. "Their own user" refers to the organization to which the user who posted the first posted information belongs. Selection button 403 is selected by the first user when they want to keep the first posted information confidential from the second user. In this case, the non-disclosure determination unit 223 can determine whether or not there is a request for non-disclosure of the first posted information by determining which of the selection buttons 401 to 403 on the non-disclosure requirement selection screen was selected, and if there is a request for non-disclosure, it can determine the level of non-disclosure.

[0041] Furthermore, the above describes a case in which the non-disclosure determination unit 223 determines the level of non-disclosure. However, it is not limited to this case; if there is only one level of non-disclosure, the non-disclosure determination unit 223 does not need to determine the level of non-disclosure.

[0042] For example, the first user who posts the first information input uses the user terminal 3 to input information into the information processing device 2 indicating whether or not the first information input should be kept confidential before posting the information input. The non-disclosure determination unit 223 then determines from the information input by the first user whether or not there is a request for non-disclosure for the first information input to be posted by the first user.

[0043] Furthermore, if the non-disclosure determination unit 223 determines that there is no request for non-disclosure of the first posted information, it may determine whether there is a request for disclosure approval for the first posted information. The person who sets the disclosure approval for the first posted information is, for example, a higher-ranking user such as an administrator or person in charge among the first users. Furthermore, if the non-disclosure determination unit 223 determines that there is a request for non-disclosure of the first posted information, it will not perform the disclosure approval determination process.

[0044] For example, if the non-disclosure determination unit 223 determines that there is no request for non-disclosure of the first posted information, i.e., that there is a request for disclosure, it sends a notification to the user terminal 3 used by the superior user requesting approval for the disclosure of the first posted information. The information indicating the user terminal 3 used by the superior user is stored in advance in the storage unit 23 of the information processing device 2 as one of the pieces of information indicating the first user to which the superior user belongs (first user information). Then, for example, the superior user uses the user terminal 3 to input information to the information processing device 2 indicating whether or not they approve the disclosure of the first posted information in response to the above notification. The non-disclosure determination unit 223 then determines from the information input by the superior user whether or not there is a request for approval for disclosure of the first posted information. For example, as shown in Figure 5, the senior user can input information indicating whether or not to approve the disclosure to the information processing device 2 using a screen for selecting whether or not to approve the disclosure (disclosure approval selection screen) displayed on the user terminal 3. The disclosure approval selection screen shown in Figure 5 displays two selection buttons 501 and 502. Selection button 501 is the button that the senior user selects when approving the disclosure of the first posted information. Selection button 502 is the button that the senior user selects when not approving the disclosure of the first posted information. In this case, the non-disclosure determination unit 223 can determine whether or not to approve the disclosure of the first posted information by determining which of the selection buttons 501 and 502 on the disclosure approval selection screen was selected.

[0045] Figure 1 shows the case where the non-disclosure determination unit 223 is provided in the information processing device 2. However, the non-disclosure determination unit 223 is not an essential component of the information processing device 2, and it is not necessary for the information processing device 2 to have the non-disclosure determination unit 223.

[0046] The distribution information generation unit 224 generates distribution information based on the information obtained by the post information acquisition unit 222. In this case, the distribution information generation unit 224 may generate distribution information using the information itself acquired by the post information acquisition unit 222, or it may generate distribution information by processing the information acquired by the post information acquisition unit 222. When the distribution information generation unit 224 generates distribution information by processing the information, it may use only a part of the information to generate the distribution information. Furthermore, the distribution information generation unit 224 may perform a fast check using AI analysis on the information acquired by the post information acquisition unit 222 before generating the distribution information.

[0047] Furthermore, if the information acquired by the posting information acquisition unit 222 includes event information, the distribution information generation unit 224 may generate distribution information by combining multiple pieces of information acquired by the posting information acquisition unit 222 that share common event information. Here, "common event information" means, for example, that at least one of the following is common: information indicating the type of event included in the event information, information indicating the location where the event occurred, and information indicating the time when the event occurred.

[0048] The distribution information generation unit 224 may, using the information acquired by the posting information acquisition unit 222, search for information related to events corresponding to pre-set types of events ("fire," "earthquake," "traffic accident," etc.) and acquire event information as a search result. Furthermore, the distribution information generation unit 224 may obtain event information not only from the text contained in the information obtained by the posting information acquisition unit 222, but also from the images contained in that information. For example, when obtaining event information related to a fire, the distribution information generation unit 224 analyzes the images contained in the information obtained by the posting information acquisition unit 222, searches for information indicating the occurrence of a fire using the analysis result of whether or not a fire is depicted in the image, and obtains event information using the information obtained as a result of the search.

[0049] Furthermore, the distribution information generation unit 224 may acquire information indicating the location where the event occurred as event information. For example, when the distribution information generation unit 224 acquires event information based on the text contained in the information acquired by the posting information acquisition unit 222, it acquires information indicating the location where the event occurred from the text or the metadata of the text. Furthermore, for example, when the distribution information generation unit 224 acquires event information based on information including an image, it may acquire information indicating the location where the event occurred by performing image analysis on the image, or by utilizing the text provided with the image, or their metadata.

[0050] Furthermore, the distribution information generation unit 224 may acquire information indicating the time when the event occurred as event information. For example, when the distribution information generation unit 224 acquires event information based on the text contained in the information acquired by the posting information acquisition unit 222, it acquires information indicating the time when the event occurred from the text or the metadata of the text. Furthermore, for example, if the distribution information generation unit 224 acquires event information based on information including an image, it may also use the text provided with the image, or their metadata, to acquire information indicating the time when the event occurred.

[0051] The distribution information generation unit 224 may generate, for example, at least one of topic information and map information as distribution information. Topic information is primarily text-based summaries of relevant information. Images may also be included in this topic information. Map information is information that shows an overview of event information on a map. For example, the map information includes a display indicating that the event occurred at the location where the event included in the event information occurred.

[0052] Furthermore, the distribution information generation unit 224 may add display information to the distribution information based on the first post information to distinguish it from distribution information based on other information, including the second post information. Examples of this display information include display information that allows the display of an icon or string of characters indicating that the distribution information is based on the first post information.

[0053] Furthermore, if the first post information obtained by the post information acquisition unit 222 includes user identification information, the distribution information generation unit 224 may include information that allows the user to be identified, which has been added to the first post information, as poster information in the distribution information based on the first post information. On the other hand, the distribution information generation unit 224 may include information indicating anonymity as poster information in the distribution information based on the second post information.

[0054] Furthermore, the distribution information generation unit 224 may add information to the distribution information based on the first post information to prioritize the display of the distribution information based on the first post information over the display of the distribution information based on the second post information. "Priority of display" means, for example, that the information is displayed in a position that is easy for the user to see on the distribution information screen (distribution information screen) displayed by the user terminal 3, such as being displayed at the starting point of screen scrolling.

[0055] The distribution information transmission unit 225 transmits the distribution information generated by the distribution information generation unit 224 to the user terminal 3. Furthermore, the distribution information transmission unit 225 narrows the range of user terminals 3 that transmit distribution information based on the first posted information compared to the range of user terminals 3 that transmit distribution information based on the second posted information.

[0056] For example, the distribution information transmission unit 225 may always set the range of user terminals 3 that transmit distribution information based on the first post information to be narrower than the range of user terminals 3 that transmit distribution information based on the second post information. Furthermore, for example, if the information processing device 2 is provided with a non-disclosure determination unit 223, the distribution information transmission unit 225 may narrow the range of user terminals 3 that transmit distribution information based on the first posted information to a narrower range than the range of user terminals 3 that transmit distribution information based on the second posted information, if the non-disclosure determination unit 223 determines that there is a request for non-disclosure regarding the first posted information. In other words, in this case, if the non-disclosure determination unit 223 determines that there is no request for non-disclosure regarding the first posted information, the distribution information transmission unit 225 does not need to narrow the range of user terminals 3 that transmit distribution information based on the first posted information to a narrower range than the range of user terminals 3 that transmit distribution information based on the second posted information.

[0057] In this case, for example, the distribution information transmission unit 225 may transmit the distribution information based on the first posted information to user terminals 3 used by some of the users who can use the information distribution service, but not to user terminals 3 used by the remaining users, thereby narrowing the range of user terminals 3 to which the distribution information based on the first posted information is transmitted. Furthermore, for example, if the information processing device 2 provides a first information distribution service and a second information distribution service, the distribution information transmission unit 225 may, for example, not transmit the distribution information based on the first posted information to the user terminal 3 used by a user who can use the first information distribution service, but transmit it to the user terminal 3 used by a user who can use the second information distribution service, thereby narrowing the range of user terminals 3 to which the distribution information based on the first posted information is transmitted. Furthermore, for example, the distribution information transmission unit 225 may narrow the range of user terminals 3 that transmit distribution information based on the first posted information by combining both of the above.

[0058] For example, the distribution information transmission unit 225 may transmit the distribution information based on the second posted information to the user terminal 3 used by all users who can utilize the information distribution service provided by the information processing device 2. For example, if the information distribution service provided by the information processing device 2 is a first information distribution service and a second information distribution service, the distribution information transmission unit 225 may transmit the distribution information based on the second posted information to both the user terminal 3 used by all users who can use the first information distribution service and the user terminal 3 used by all users who can use the second information distribution service.

[0059] Furthermore, if the distribution information generation unit 224 generates distribution information based on publicly available information, the range of user terminals 3 to which the distribution information transmission unit 225 transmits the distribution information based on the publicly available information may be the same as the range of user terminals 3 to which the distribution information based on the second posted information is transmitted.

[0060] Furthermore, if the first user is an organization, the distribution information transmission unit 225 may include user terminals 3 used by the organization to which the user who posted the first post belongs, even if the non-disclosure determination unit 223 determines that there is a request for non-disclosure of the first posted information.

[0061] Furthermore, if the non-disclosure determination unit 223 determines the level of non-disclosure for the first posted information, the distribution information transmission unit 225 may change the range of user terminals 3 to which distribution information based on the first posted information is transmitted, according to the level of non-disclosure for the first posted information determined by the non-disclosure determination unit 223. In this case, if the non-disclosure determination unit 223 determines whether there are multiple stages of non-disclosure requests for the first posted information and determines the level of non-disclosure, the distribution information transmission unit 225 may change the range of user terminals 3 to which distribution information based on the first posted information is transmitted, according to the stage of whether or not there are non-disclosure requests for the first posted information determined by the non-disclosure determination unit 223.

[0062] For example, if there are both authentication-time non-disclosure and posting-time non-disclosure options, the distribution information transmission unit 225 may narrow the range of user terminals 3 to which it transmits distribution information based on the first posting information if the non-disclosure determination unit 223 determines that there is a request for authentication-time non-disclosure for the first posting information, or if the non-disclosure determination unit 223 determines that there is a request for posting-time non-disclosure for the first posting information.

[0063] As a more concrete example, consider a case where the information distribution service provided by the information processing device 2 is a first information distribution service and a second information distribution service, and the non-disclosure determination unit 223 determines whether or not there is a request for non-disclosure during user authentication and whether or not there is a request for non-disclosure when posting the first posted information, respectively. In this case, for example, if the non-disclosure determination unit 223 determines that there is a request for non-disclosure at the time of authentication for the first posted information, the distribution information based on the first posted information may be transmitted to the user terminal 3 used by the organization to which the user who posted the first posted information belongs, among the users who can use the second information distribution service, but not to the user terminal 3 used by users other than the organization to which the user who posted the first posted information belongs, among the users who can use the second information distribution service, or to the user terminal 3 used by users who can use the first information distribution service. Furthermore, for example, if the non-disclosure determination unit 223 determines that there is a request for non-disclosure of the first posted information at the time of posting, the distribution information based on the first posted information may be transmitted to the user terminal 3 used by a user who is able to use the second information distribution service, but not to the user terminal 3 used by a user who is able to use the first information distribution service. In the example above, even if the first posted information is set to private, it is still distributed by the second information distribution service. This is because, for example, the usage fee for the first information distribution service is cheaper than the usage fee for the second information distribution service (for example, the first information distribution service is free to use, and the second information distribution service is available for a fee), and this is to ensure that useful information is more likely to be distributed by the second information distribution service.

[0064] Furthermore, if the non-disclosure determination unit 223 determines that there is a request for disclosure approval for the first posted information, the distribution information transmission unit 225 may broaden the range of user terminals 3 to which it transmits distribution information based on the first posted information compared to when the non-disclosure determination unit 223 determines that there is no request for disclosure approval for the first posted information. In this case, if the non-disclosure determination unit 223 determines that there is a request for disclosure approval for the first posted information, the distribution information transmission unit 225 may set the range of user terminals 3 that transmit distribution information based on the first posted information to be the same as the range of user terminals 3 that transmit distribution information based on the second posted information. Alternatively, even if the non-disclosure determination unit 223 determines that there is a request for disclosure approval for the first posted information, the distribution information transmission unit 225 may narrow the range of user terminals 3 that transmit distribution information based on the first posted information compared to the range of user terminals 3 that transmit distribution information based on the second posted information.

[0065] Furthermore, if the post information acquired by the post information acquisition unit 222 includes event information, the distribution information transmission unit 225 may refrain from transmitting the distribution information based on the post information that shares the event information to the user terminal 3 if there are no distribution information based on post information that shares the event information that is equal to or greater than a certain threshold among the distribution information based on the post information generated by the distribution information generation unit 224. In this case, the threshold may be set so that the threshold for distribution information based on the second post information is greater than the threshold for distribution information based on the first post information.

[0066] Furthermore, the distribution information transmission unit 225 may, in response to a filtering request from the user terminal 3, extract distribution information corresponding to the filtering request from the distribution information transmitted to the user terminal 3 and transmit it to the user terminal 3. Examples of filtering request conditions (filtering conditions) include the type of information that forms the basis of the distribution information, the range of locations where the event occurred, the range of times when the event occurred, the type of event, and search keywords for the text contained in the posted information. In this case, for example, if a user terminal 3 requests to narrow down the first posted information, the distribution information transmission unit 225 extracts the distribution information based on the first posted information from the distribution information transmitted to the user terminal 3 and transmits it to the user terminal 3. As a result, in the information processing device 2 according to Embodiment 1, the user can perform a search narrowed down to the first posted information, even though they can view distribution information based on the first posted information which is considered to have value or reliability and distribution information based on the second posted information which is considered to have low value or reliability. For example, as shown in Figure 6, a user can input information indicating filtering conditions into the information processing device 2 using a screen for setting filtering conditions (filtering condition setting screen) displayed on the user terminal 3. In the example in Figure 6, four input fields 601 to 604 are displayed. Input field 601 is used by the user to specify the period during which the event occurred (the period during which it was published or posted). Input field 602 is used by the user to specify at least one of the keywords to be searched for and keywords to be excluded from the search. Input field 603 is used by the user to specify the source of the information (at least one of the posted information and the published information). Input field 604 is used by the user to specify the type of event. In this case, the distribution information generation unit 224 can obtain the filtering request by acquiring the information entered into input fields 601 to 604 on the filtering condition setting screen.

[0067] Next, an example of the distribution information screen displayed by user terminal 3 will be explained with reference to Figures 7 to 10. Figures 7 to 9 show the distribution information screen provided by the second information distribution service, while Figure 10 shows the distribution information screen provided by the first information distribution service. The distribution information screens shown in Figures 7 to 9 are examples of distribution information screens displayed on a PC.

[0068] Figure 7 shows an example of a distribution information screen displayed on user terminal 3, which is not subject to receiving distribution information based on the first posted information. In the distribution information screen shown in Figure 7, two display fields 701 and 702 are displayed. Display field 701 is the field that displays topic information from the distribution information. Display field 702 is the field that displays map information from the distribution information. In the screen shown in Figure 7, the distribution information based on the first post, which has been set to private, is not displayed; only the other distribution information 703 is shown. The number shown for distribution information 703 indicates the number of pieces of information (posted information and publicly available information) that form the basis of that distribution information 703.

[0069] Figure 8 shows an example of a distribution information screen displayed on user terminal 3, which is within the range of users receiving distribution information based on the first posted information. Topic information and map information are also displayed on the distribution information screen shown in Figure 8. The distribution information screen shown in Figure 8 displays not only the other distribution information mentioned above, but also distribution information 801 based on the first post, which is kept private, in addition to the other distribution information shown in Figure 7. The number shown for distribution information 801 indicates the number of pieces of information (posted information and published information) that form the basis of that distribution information 801. Furthermore, distribution information 801 based on the first post is displayed above the other distribution information, making it easier for users to see. In addition, in the example in Figure 8, identification information 802 and 803 are displayed. Identification information 802 is information attached to the topic information. Identification information 802 is a string. Identification information 803 is information attached to the map information. Identification information 803 is an icon. This identification information 802 and 803 makes it easy for the user to understand which information is the distribution information based on the first posted information. Furthermore, in the example shown in Figure 8, the text of the topic information distributed based on the first information distribution service is displayed differently (highlighted) from the text of the other distributed information. This also makes it easy for users to understand which information is distributed based on the first posted information.

[0070] Figure 9 shows another example of the distribution information screen displayed on user terminal 3, which is within the range of users receiving distribution information based on the first posted information. In the distribution information screen shown in Figure 9, topic information and map information are also displayed. The distribution information screen shown in Figure 9, similar to the distribution information screen shown in Figure 8, displays not only the other distribution information mentioned above, but also distribution information based on the first post, which has been made private. Furthermore, in the distribution information screen shown in Figure 9, the identification information 802 has been changed to identification information 901 compared to the distribution information screen shown in Figure 8. Identification information 901 is information added to the map information. Identification information 901 is a string.

[0071] Figure 10 shows an example of a distribution information screen displayed on user terminal 3, which is within the range of recipients of distribution information based on the first posted information. The distribution information screen shown in Figure 10 is an example of a distribution information screen displayed on a smartphone. In the distribution information screen shown in Figure 10, two display fields 1001 and 1002 are displayed. Display field 1001 is the field that displays topic information from the distribution information. Display field 1002 is the field that displays map information from the distribution information. The screen shown in Figure 10 displays distribution information based on the first post, which has been set to private, and other distribution information. The two leftmost pieces of topic information displayed in display field 1001 are the distribution information based on the first post. The numbers displayed in the topic information indicate the number of pieces of information (posts and published information) that form the basis of that topic information. Furthermore, in display field 1001, the distribution information based on the first post is displayed to the left of the other distribution information, making it easier for the user to view. In addition, in the example in Figure 10, identification information 1003 and 1004 are displayed. Identification information 1003 is information added to the topic information. Identification information 1003 is an icon. Identification information 1004 is information added to the map information. Identification information 1004 is an icon. These identification information 1003 and 1004 allow the user to easily understand which information is the distribution information based on the first posted information. In addition, in the example shown in Figure 10, the report button 1005 is displayed. The report button 1005 is the button that users select when making a post.

[0072] Next, an example of the operation of the information processing device 2 according to Embodiment 1 will be explained with reference to the flowchart shown in Figure 11. In the following explanation, the case in which the posting information acquisition unit 222 acquires only posting information will be used as an example.

[0073] In an example of the operation of the information processing device 2 according to Embodiment 1, as shown in Figure 11, for example, first the user authentication unit 221 determines whether the user making the post is the first user (step ST101).

[0074] In step ST101, if the user authentication unit 221 determines that the user making the post is the first user, the post information acquisition unit 222 acquires the post information made by that user as the first post information (step ST102).

[0075] Next, the distribution information generation unit 224 generates distribution information based on the first post information obtained by the post information acquisition unit 222 (step ST103).

[0076] Next, the distribution information transmission unit 225 transmits the distribution information generated by the distribution information generation unit 224 to the user terminal 3 within a narrower range than the distribution information based on the second posted information (step ST104).

[0077] Here, a specific example of step ST104 will be explained with reference to the flowchart shown in Figure 12 and Figure 13. Here, the first user is an organization, and the information distribution services provided by the information processing device 2 are the first information distribution service and the second information distribution service. Furthermore, it is assumed that the information processing device 2 has a non-disclosure determination unit 223 that determines whether or not information should be kept confidential at the time of authentication and at the time of posting. In addition, if the non-disclosure determination unit 223 determines that there is no request for non-disclosure, it will determine whether or not there is a request for disclosure approval.

[0078] In this case, for example as shown in Figure 12, the non-disclosure determination unit 223 first determines whether or not there is a request for non-disclosure at the time of authentication for the first posted information (step ST1041).

[0079] In step ST1041, if the non-disclosure determination unit 223 determines that there is a request for non-disclosure at the time of authentication for the first posted information, the distribution information transmission unit 225 transmits the distribution information generated by the distribution information generation unit 224 to the user terminal 3 used by the organization to which the user who posted the first posted information belongs, among the users who can use the second information distribution service, but does not transmit it to the user terminal 3 used by users other than the said organization among the users who can use the second information distribution service, or to the user terminal 3 used by users who can use the first information distribution service (step ST1042).

[0080] On the other hand, in step ST1041, if the non-disclosure determination unit 223 determines that there is no request for non-disclosure at the time of authentication for the first posted information, it determines whether or not there is a request for non-disclosure at the time of posting for the first posted information (step ST1043).

[0081] In step ST1043, if the non-disclosure determination unit 223 determines that there is no request for non-disclosure of the first posted information, it determines whether there is a request for approval of disclosure of the first posted information (step ST1044).

[0082] In step ST1044, if the non-disclosure determination unit 223 determines that there is no request for disclosure approval for the first posted information, or if the non-disclosure determination unit 223 determines in step ST1043 that there is a request for non-disclosure at the time of posting for the first posted information, the distribution information transmission unit 225 transmits the distribution information generated by the distribution information generation unit 224 to the user terminal 3 used by users who can use the second information distribution service, but does not transmit it to the user terminal 3 used by all users who can use the first information distribution service (step ST1045).

[0083] On the other hand, in step ST1044, if the non-disclosure determination unit 223 determines that there is a request for disclosure approval for the first posted information, the distribution information transmission unit 225 transmits the distribution information generated by the distribution information generation unit 224 to both the user terminal 3 used by all users who can use the first information distribution service and the user terminal 3 used by all users who can use the second information distribution service (step ST1046).

[0084] On the other hand, if the user authentication unit 221 does not determine in step ST101 that the user using the user terminal 3 is the first user, the posting information acquisition unit 222 acquires the posting information posted by that user as the second posting information (step ST105).

[0085] Next, the distribution information generation unit 224 generates distribution information based on the second post information obtained by the post information acquisition unit 222 (step ST106).

[0086] Next, the distribution information transmission unit 225 transmits the distribution information generated by the distribution information generation unit 224 to the user terminal 3 (step ST107). In this case, for example, if the information distribution service provided by the information processing device 2 is a first information distribution service and a second information distribution service, the distribution information transmission unit 225 transmits the distribution information to both the user terminal 3 used by all users who can use the first information distribution service and the user terminal 3 used by all users who can use the second information distribution service.

[0087] As described above, according to this embodiment 1, the information processing device 2 includes a posting information acquisition unit 222 that acquires posting information which is first posting information posted by a first user and second posting information posted by a second user other than the first user; a distribution information generation unit 224 that generates distribution information based on the posting information acquired by the posting information acquisition unit 222; and a distribution information transmission unit 225 that transmits the distribution information generated by the distribution information generation unit 224 to a user terminal 3. The distribution information transmission unit 225 narrows the range of user terminals 3 that transmit distribution information based on the first posting information compared to the range of user terminals 3 that transmit distribution information based on the second posting information. As a result, the information processing device 2 according to Embodiment 1 can change the scope of public access to the distributed information for the first posted information and the second posted information, enabling more appropriate information distribution than before.

[0088] Furthermore, according to this embodiment 1, the information processing device 2 includes a user authentication unit 221 that determines whether a user is the first user, and the posting information acquisition unit 222 acquires posting information posted by a user determined to be the first user by the user authentication unit 221 as first posting information, and acquires posting information posted by a user not determined to be the first user by the user authentication unit 221 as second posting information. As a result, in the information processing device 2 according to Embodiment 1, the scope of disclosure of distribution information based on first posted information by a first user who has been authenticated is narrower than the scope of disclosure of distribution information based on second posted information by a second user who has not been authenticated, thereby distinguishing information that is considered to have value or reliability from other information. In general, social networking services (SNS) distribute information posted by authenticated users widely. In contrast, the information processing device 2 according to Embodiment 1 restricts the scope of public access to information posted by authenticated users.

[0089] Furthermore, according to this embodiment 1, the first posting information acquired by the posting information acquisition unit 222 is accompanied by information that identifies the first user who posted the first posting information, and the distribution information generation unit 224 includes the information that identifies the first user attached to the first posting information in the distribution information based on the first posting information, and includes information indicating anonymity in the distribution information based on the second posting information. As a result, the information processing device 2 according to Embodiment 1 can identify the first user who posted the first posted information.

[0090] Furthermore, according to this embodiment 1, the information distribution service provided by the information processing device 2 is a first information distribution service and a second information distribution service, and the distribution information transmission unit 225 does not transmit the distribution information based on the first posted information to the user terminal 3 used by a user who is able to use the first information distribution service, but transmits it to the user terminal 3 used by a user who is able to use the second information distribution service. As a result, the information processing device 2 according to Embodiment 1 can narrow down the information distribution service to which the distributed information based on the first posted information is published, thereby enabling more appropriate information distribution than before.

[0091] Furthermore, according to this embodiment 1, the first information distribution service is an information distribution service used by the information processing device 2 when acquiring posted information and when distributing distribution information based on said posted information, and the second information distribution service is an information distribution service used by the information processing device 2 when distributing distribution information based on posted information acquired via the first information distribution service. As a result, the information processing device 2 according to Embodiment 1 can narrow down the information distribution service to which the distributed information based on the first posted information is published, thereby enabling more appropriate information distribution than before.

[0092] Furthermore, according to this embodiment 1, the system includes a non-disclosure determination unit 223 that determines whether or not there is a request for non-disclosure regarding the first posted information acquired by the posted information acquisition unit 222, and the distribution information transmission unit 225 narrows the range of user terminals 3 that transmit distribution information based on the first posted information to a smaller range of user terminals 3 that transmit distribution information based on the second posted information when the non-disclosure determination unit 223 determines that there is a request for non-disclosure regarding the first posted information. As a result, the information processing device 2 according to Embodiment 1 allows the user to set whether or not to request non-disclosure, enabling more appropriate information distribution than before.

[0093] Furthermore, according to this embodiment 1, the non-disclosure determination unit 223 determines the level of non-disclosure when it determines that there is a request for non-disclosure of the first posted information, and the distribution information transmission unit 225 changes the range of user terminals 3 to which it transmits distribution information based on the first posted information, according to the level of non-disclosure determined by the non-disclosure determination unit 223 when the non-disclosure determination unit 223 determines that there is a request for non-disclosure of the first posted information. As a result, in the information processing device 2 according to Embodiment 1, the user can set multiple levels for the scope of disclosure of the first posted information.

[0094] Furthermore, according to this embodiment 1, the non-disclosure determination unit 223 determines the level of non-disclosure by determining whether there are multiple stages of non-disclosure requests for the first posted information. As a result, in the information processing device 2 according to Embodiment 1, the user can set multiple levels for the scope of disclosure of the first posted information.

[0095] Furthermore, according to this embodiment 1, the first user is an organization, and even if the non-disclosure determination unit 223 determines that there is a request for non-disclosure regarding the first posted information, the distribution information transmission unit 225 includes the user terminal 3 used by the organization to which the user who posted the first posted information belongs in the scope of the user terminal 3 to which the distribution information based on the first posted information is transmitted. As a result, in the information processing device 2 according to Embodiment 1, even if the scope of public access to the first posted information is narrowed, the organization to which the poster of the first posted information belongs will be able to view the distribution information based on the first posted information.

[0096] Furthermore, according to this embodiment 1, the information distribution service provided by the information processing device 2 is a first information distribution service used by the information processing device 2 when acquiring posted information and distributing distribution information based on said posted information, and a second information distribution service used by the information processing device 2 when distributing distribution information based on the posted information acquired via the first information distribution service. The non-disclosure determination unit 223 determines whether there is a request for non-disclosure in two stages for the first posted information, and the distribution information transmission unit 225, if the non-disclosure determination unit 223 determines that there is a request for non-disclosure in the first stage for the first posted information, transmits the distribution information based on said first posted information to the second The information distribution service is available to send the first posted information to the user terminal 3 used by the first user who posted the information, but not to the user terminal 3 used by other users who are available to use the first information distribution service, nor to the user terminal 3 used by users who are available to use the second information distribution service. If the non-disclosure determination unit 223 determines that there is a second-stage request for non-disclosure of the first posted information, the distribution information based on the first posted information is sent to the user terminal 3 used by the user who is available to use the first information distribution service, but not to the user terminal 3 used by users who are available to use the second information distribution service. As a result, in the information processing device 2 according to Embodiment 1, the user can set multiple levels for the scope of disclosure of the first posted information.

[0097] Furthermore, according to this embodiment 1, if the non-disclosure determination unit 223 determines that there is no request for non-disclosure of the first posted information, it determines whether there is a request for disclosure approval for the first posted information, and if the non-disclosure determination unit 223 determines that there is a request for disclosure approval for the first posted information, the distribution information transmission unit 225 widens the range of user terminals 3 to which it transmits distribution information based on the first posted information compared to when the non-disclosure determination unit 223 determines that there is no request for disclosure approval for the first posted information. As a result, in the information processing device 2 according to Embodiment 1, the higher-level user can make a final decision on whether or not to publish the distribution information based on the first posted information.

[0098] Furthermore, according to this embodiment 1, when the non-disclosure determination unit 223 determines that there is a request for disclosure approval for the first posted information, the distribution information transmission unit 225 sets the range of user terminals 3 to which distribution information based on the first posted information is the same as the range of user terminals 3 to which distribution information based on the second posted information is transmitted. As a result, in the information processing device 2 according to Embodiment 1, the higher-level user can make a final decision on whether or not to publish the distribution information based on the first posted information.

[0099] Furthermore, according to this embodiment 1, the distribution information generation unit 224 adds display information to the distribution information based on the first post information to distinguish it from the distribution information based on the second post information. As a result, in the information processing device 2 according to Embodiment 1, it becomes easier for the user to distinguish the distribution information based on the first posted information from the distribution information based on the second posted information.

[0100] Furthermore, according to this embodiment 1, in response to a request from the user terminal 3 to narrow down the first posted information, the distribution information transmission unit 225 extracts the distribution information based on the first posted information from the distribution information transmitted to the user terminal 3 and transmits it to the user terminal 3. This makes it easier for users to search for distribution information based on the first posted information in the information processing device 2 according to Embodiment 1.

[0101] Furthermore, according to this embodiment 1, the distribution information generation unit 224 adds control information to the distribution information based on the first post information to prioritize the display of the distribution information based on the first post information over the display of the distribution information based on the second post information. As a result, in the information processing device 2 according to Embodiment 1, the user can view the distribution information based on the first posted information more easily than the distribution information based on the second posted information.
