[0010] The following describes embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. Furthermore, not all of the configurations described in the embodiments are necessarily essential as means for solving the problems. For clarity of explanation, the following description and drawings have been omitted and simplified as appropriate.

[0011] <First Embodiment> A configuration example of the information processing system according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing a configuration example of the information processing system according to the first embodiment.

[0012] As shown in Fig. 1, the information processing system according to this embodiment may include a server device 1 and an information terminal device 2 connectable to the server device 1 via a wireless network. The network is not limited to a wireless network and may include at least a wired network. The server device 1 is a general-purpose server device, and the information terminal device 2 is a general-purpose information terminal device used by any user. Therefore, the information processing system may be configured with the server device 1.

[0013] The server device 1 is a device that can be used by a posting service provider that provides a posting service for reviews and the like. The information terminal device 2 is a device used by users of the services provided by stores and other establishments that are the subject of postings at their facilities, and is a device that acquires and posts user information including emotional information and biometric information, which will be described later. Hereinafter, to distinguish from the posting service, the services provided by stores and other establishments that are the subject of postings at their facilities will be referred to as provided services.

[0014] Examples of the provided services that can be posted include various types of provided services such as food and drink services, nursing care services, medical services, accommodation services, and massage services. A posting service provider accepts posts about one or more provided services from an information terminal device 2 used by a poster who has used each provided service. In addition, the posted information can be viewed on an external device such as an arbitrary information terminal device.

[0015] (Server device 1) The server device 1 is configured as a server computer and can include a control unit 10, a communication unit 16, and an information storage unit 17. The server device 1 can also be configured as a server system in which functions are distributed across multiple devices. For example, the server device 1 can include a first server device that is installed at a business company that provides a posting service and is mainly responsible for communication with external devices such as an information terminal device 2, and a second server device that is connected to the first server device via a network and is responsible for the main functions of the server device 1.

[0016] The control unit 10 controls the entire server device 1. The control unit 10 may be realized, for example, by a processor such as a CPU (Central Processing Unit), a working memory, and a non-volatile storage device storing a control program. The program may include a program that, when executed by the processor, realizes the functions of the server device 1. The control unit 10 may also be realized using a user-programmable integrated circuit, such as an FPGA (field-programmable gate array) or a microcomputer. The control unit 10 may include a communication control unit 11, a posting acceptance unit 12, a user information acquisition unit 13, and a reflection processing unit 14, which are functional blocks realized by the operation of a program in the server device 1, or may further include a determination unit 15 in addition to these.

[0017] The communication unit 16 communicates with external devices such as the information terminal device 2. The communication unit 16 is a communication unit that communicates in accordance with a wireless communication standard such as Wi-Fi (registered trademark; the same applies below), and is connected to the Internet. The communication control unit 11 controls communication with external devices via the communication unit 16, thereby controlling the acquisition of information from the information terminal device 2 or the disclosure of information to any external device. Note that communication between the server device 1 and external devices is controlled by the communication control unit 11, and is performed between the server device 1 and, for example, the post acceptance unit 12 and the user information acquisition unit 13. However, hereinafter, communication with external devices will simply be described as communication via the communication unit 16.

[0018] The information storage unit 17 is a storage device such as an SSD (Solid State Drive) or HDD (Hard Disk Drive) that stores various information used by the server device 1. The information storage unit 17 stores, as one type of information to be stored, posted information, which is information posted so as to be viewable from an external device via the Internet. The information storage unit 17 stores information about various services to which posts are made in the posting service. The services to which posts are made may include information on whether or not biometric information of users who use the service is permitted to be reflected in posts. Whether or not biometric information of users who use the service is permitted to be reflected in posts depends on the contract between the operator of the posting service and the operator of each service. The following description is based on the assumption that biometric information of users who use the service is permitted to be reflected in posts.

[0019] The post receiving unit 12 receives posts for the provided services via the communication unit 16. The post receiving unit 12 can receive posts not only from the information terminal device 2 used by the user receiving the provided service, but also from information terminal devices used by other contributors. In other words, the post receiving unit 12 receives posts for each provided service from the information terminal devices of various users. For example, the post receiving unit 12 sets up an input form on a web page corresponding to each provided service and receives the posts. The post receiving unit 12 passes posted information indicating the received post to the reflection processing unit 14.

[0020] Furthermore, the posting receiving unit 12 acquires information for identifying the poster in addition to the posted content. The information for identifying the poster may include registered user information such as an ID, as well as location information when the provided service to which the posting is directed was used. The registered user information is, for example, information indicating the user of the posting service, i.e., the poster, obtained by registering to use a posting service application program (hereinafter referred to as a posting service app). The posting service app is an application program that can be installed in an information terminal device used by the poster, such as the information terminal device 2, to enable posting to the server device 1.

[0021] The user information acquisition unit 13 acquires emotional information based on biometric information when the user uses the provided services. That is, the user information acquisition unit 13 acquires emotional information from the user's information terminal device 2 during the period in which the user uses each provided service. A user of a provided service is a user of the facility that provides the provided service. Emotional information can be information indicating, for example, a calm state, a happy state, a sad state, an irritated state, etc. Here, a user being in a happy state means that the user has a positive emotion. A user being in a sad or irritated state means that the user has a negative emotion.

[0022] The user information acquiring unit 13 acquires the user's biometric information from the information terminal device 2 used by the user via the communication unit 16, and acquires emotional information by calculating, for example, estimating emotional information from the biometric information. The user information acquiring unit 13 estimates which state the user is in from a plurality of states such as a calm state, a happy state, a sad state, or an irritated state, based on information indicating the user's heart rate variability received as biometric information, for example.

[0023] Alternatively, the user information acquisition unit 13 acquires emotional information of the user from the information terminal device 2 used by the user via the communication unit 16. In this case, the emotional information can be acquired by, for example, estimating the emotional information from biometric information acquired by the information terminal device 2. In this case, the biometric information acquisition unit 25 of the information terminal device 2 may estimate which state the user is in from among multiple states based on, for example, information indicating the user's heart rate variability received as biometric information from the biometric sensor 30. The user information acquisition unit 13 or the biometric information acquisition unit 25 that estimates the emotional information may be equipped with emotion recognition AI (Artificial Intelligence) that has been machine-learned to input biometric information and output emotional information.

[0024] The biometric information or emotional information acquired by the user information acquisition unit 13 is a type of user information. The timing of acquisition of the user information by the user information acquisition unit 13 may be when the information terminal device 2 acquires user information before posting, at the same time as the user of the information terminal device 2 posts as a poster, or after the post has been made. By having the user information acquisition unit 13 acquire user information from the information terminal device 2 that is the poster after posting, it is possible to avoid acquiring unnecessary information unrelated to the post. The user information acquisition unit 13 stores the acquired emotional information in the information storage unit 17.

[0025] The reflection processing unit 14 reflects the emotion information acquired by the user information acquisition unit 13 in the post accepted by the post acceptance unit 12. For example, the reflection processing unit 14 reflects the emotion information in the post information indicating the post received from the post acceptance unit 12, and stores the information in the information storage unit 17 in a state that can be viewed from an external device via the Internet or the like.

[0026] For example, the reflection processing unit 14 can reflect emotional information directly in a post received by the post receiving unit 12 without analyzing the content of the post. When the emotional information indicates a positive emotion, the reflection processing unit 14 reflects the emotional information by using a bright color tone in the display indicating the post, or by displaying an icon such as a character with a happy image alongside the post. When the emotional information indicates a negative emotion, the reflection processing unit 14 reflects the emotional information by using a muted color tone in the display indicating the post, or by displaying an icon such as a character with a bored image alongside the post.

[0027] Alternatively, the reflection processing unit 14 may analyze the content of the post received by the post receiving unit 12 and reflect emotional information based on the analysis results. For example, the reflection processing unit 14 may analyze the content of the text post received by the post receiving unit 12 using natural language processing or the like, determine whether the post content is positive or negative, and change the reflection method according to the determination result, as exemplified below.

[0028] If the posted content is positive and the emotional information is a positive emotion, the reflection processing unit 14 can add information that further enlivens the posted content, such as displaying a character with a bright expression looking up.

[0029] Furthermore, if the posted content is positive and the emotional information is negative, the reflection processing unit 14 can add information that casts a dull, questioning look on the posted content, such as by displaying a character with a questioning expression tilting its head.

[0030] Furthermore, when the posted content is negative and the emotional information is positive, the reflection processing unit 14 can add information that jokingly questions the posted content, such as by displaying a smiling character with its head tilted.

[0031] Furthermore, when the posted content is negative and the emotional information is a negative emotion, the reflection processing unit 14 can add information that sadly agrees with the posted content, such as by displaying a character with a disappointed expression.

[0032] The determination unit 15 determines whether or not the provided service that is the subject of the posted information corresponds to the provided service from which the emotion information was acquired when the reflection processing unit 14 reflects the information. In other words, the determination unit 15 determines whether or not the poster who posted the information about the provided service corresponds to a user who used the provided service.

[0033] For example, the determination unit 15 determines whether a poster who posted a message about a provided service is a user who used the provided service. If the determination unit 15 determines that the poster is a user who used the provided service, the reflection processing unit 14 may reflect the user's emotional information in the content posted by the poster about the provided service. The reflection processing unit 14 does not reflect the poster's emotional information in the message posted by a poster who posted without using the provided service. Furthermore, the reflection processing unit 14 may restrict posts by posters who post without using the provided service, according to the determination result of the determination unit 15.

[0034] The determination unit 15 can store location information obtained by converting the address of the facility where the provided service that was the subject of the post into latitude and longitude, and use the information to determine whether the poster is a user who has used the provided service. If the provided service is a food and drink service, the facility would be, for example, a restaurant.

[0035] For example, the user information acquisition unit 13 is configured to acquire location information indicating the latitude and longitude at the time the biometric information or emotional information was acquired together with the user's biometric information or emotional information from the information terminal device 2. The determination unit 15 then determines whether there is a match, taking into account an error range, between the facility location information and the location information at the time the biometric information or emotional information was acquired, and if there is a match, determines that the poster who posted to the provided service is a user who used the provided service. Note that the determination unit 15 does not need to store the facility location information, but may acquire it at the time of determination.

[0036] In this way, the determination unit 15 may determine that the poster of the post regarding the provided service is a user who has used the provided service when the location information of the facility that provides the provided service to be posted matches the location information associated with the emotion information acquired by the user information acquisition unit 13. Of course, here, the match between the two pieces of location information may be information that can be considered to match the two pieces of location information, and may be within a range that can be considered to be an error.

[0037] The determination unit 15 may further use time information to make the determination. For example, even if the determination unit 15 determines that a poster who posted a message to a provided service is a user who used the provided service based on the location information, if the posting date and the usage date of the provided service are different, the determination unit 15 may determine that the poster does not correspond to a user who used the provided service. For example, if the posting date is 10 to 20 days or more after the usage date of the provided service, the determination unit 15 may determine that the poster does not correspond to a user who used the provided service. Then, if there is such a difference between the posting date and the usage date, the reflection processing unit 14 may restrict posting by the user or may restrict the reflection of emotion information on the post.

[0038] The reflection processing unit 14 reflects the emotional information acquired by the user information acquisition unit 13 in the posts received by the post receiving unit 12, but may also reflect only the emotional information as a post even when there is no post. In this case, there is no need for a determination by the determination unit 15. Even in this case, a person who views a post based on such emotional information can use it to determine whether to use the provided service.

[0039] (Information terminal device 2) The information terminal device 2 may include a control unit 20, a communication unit 26, a display unit 27, an input unit 28, a GNSS receiving unit 29, and a biometric sensor 30. GNSS stands for Global Navigation Satellite System. The control unit 20 may include a communication control unit 21, a display control unit 22, an input control unit 23, a position information acquisition unit 24, and a biometric information acquisition unit 25, which perform the main functions of the information terminal device 2.

[0040] The information terminal device 2 is configured as a portable computer such as a mobile phone, smartphone, mobile computer, or wearable device. Examples of wearable devices include a smart watch, a smart ring, smart glasses, and smart earphones. The information terminal device 2 can also be configured as, for example, a wearable device equipped with a biosensor 30 and a mobile phone, smartphone, or mobile computer that can communicate with the wearable device.

[0041] The control unit 20 controls the entire information terminal device 2. The control unit 20 may be realized by, for example, a processor such as a CPU, a working memory, and a non-volatile storage device that stores a control program. This program may include a program that, when executed by the processor, realizes the functions of the information terminal device 2. The control unit 20 may also be realized by using a programmable integrated circuit, such as an FPGA or a microcomputer. The information terminal device 2 may also be called an information processing device.

[0042] The communication unit 26 communicates with external devices such as the server device 1. The communication unit 26 may be, for example, a communication unit such as the communication unit 16. The communication control unit 21 controls communication with external devices via the communication unit 26. Note that communication between the information terminal device 2 and external devices is controlled by the communication control unit 21, but hereinafter, communication with external devices will simply be described as communication via the communication unit 26.

[0043] The communication unit 26 may include a communication unit for Wi-Fi or any other mobile communication method for communicating with the server device 1, as well as a communication unit for communicating with a wearable device in accordance with a short-range wireless communication standard such as Bluetooth (registered trademark).

[0044] The display unit 27 may be configured with a display device such as a liquid crystal panel, an organic electroluminescence panel, etc. The display control unit 22 controls the display on the display unit 27. Although the display on the display unit 27 is controlled by the display control unit 22, the display will be described below simply as the display on the display unit 27.

[0045] The input unit 28 is a part that accepts operations by the user and can also be referred to as an operation unit. The input unit 28 may be configured with at least one of physical keys and software keys, or may be configured with a separately provided voice input unit and voice recognition unit, or may be configured with both. The input unit 28 may also include a touch sensor incorporated into the display unit 27. In that case, the information terminal device 2 will include a touch panel as an example of the display unit 27 and the input unit 28.

[0046] The input control unit 23 controls the input at the input unit 28. For example, the operation content received by the input unit 28 is transmitted to the input control unit 23, and the input control unit 23 controls other parts of the control unit 20 in accordance with the operation content. Note that although the input at the input unit 28 is controlled by the input control unit 23, the input will be described below simply as the input at the input unit 28.

[0047] As described above with respect to the server device 1, the user of the information terminal device 2 is a user who has used each provided service and can become a contributor who posts information related to the provided service. A posting service app is installed in advance in the information terminal device 2, and the user can register as a member or user using the posting service app. By registering with such a posting service app, the user can post to the posting service from the information terminal device 2.

[0048] In addition, this posting service app may allow the user to set whether to allow or disallow the tracking of usage of provided services based on location information and the acquisition of user information including biometric information or emotional information when using the provided services. Furthermore, the posting service app may allow the user to specify the provided services to which the user will post, the genre of the provided services to which emotional information will be reflected when posting, and the region. In such a service requiring membership or user registration, it may be desirable for the user to receive an incentive, such as a discount on the next use of the same provided service, in return for tracking usage and acquiring user information.

[0049] Such a posting service app is configured to display a user interface (UI) image on the display unit 27 and to accept input of posting content, including the above-mentioned member registration or user registration, permission / non-permission settings, etc., from the input unit 28.

[0050] The GNSS receiver 29 is a receiver for GNSS, and receives position information from GNSS and the time information at the time of acquisition, and passes it to the position information acquisition unit 24. The position information acquisition unit 24 acquires the position information and time information. The position information acquisition unit 24 passes the acquired information to the biometric information acquisition unit 25 to indicate the position of the biometric information or emotional information, etc.

[0051] The biosensor 30 is a sensor group consisting of one or more types of sensors that acquire biometric information of a user of the provided service, or a device equipped with such a sensor group. For example, the biosensor 30 can be a wearable device such as a bracelet, a ring, glasses, or an in-ear type. The biosensor 30 passes the detected information to the biometric information acquisition unit 25. If the biosensor 30 is housed in a separate housing from the main body of the information terminal device 2, it will include, in addition to one or more types of sensors, a communication unit that communicates wirelessly or wired with the main body to pass the detected information to the main body.

[0052] The biosensor 30 detects biometric information that can determine or estimate the user's emotions from the detection results or temporal changes in the detection results. The biometric information can also be referred to as vital information. The biometric information can be, for example, pulse wave information indicating pulse fluctuations as described above, but can also be other information such as body temperature information or blood pressure information. The pulse wave information is also referred to as heart rate information. The biometric information can be one or more of various information such as pulse rate, body temperature, respiratory rate, brain waves, and cerebral blood flow. Cerebral blood flow can be detected, for example, by an optical sensor mounted on an in-ear wearable device worn on the ear.

[0053] The biometric sensor 30 may also include a voice input unit configured, for example, by a microphone that inputs the user's voice. In this case, the biometric information acquisition unit 25 or the user information acquisition unit 13 analyzes features such as voice intonation and volume from the voice data acquired by the voice input unit, recognizes emotions, and acquires them as emotional information. The biometric sensor 30 may also include, for example, a camera that captures an image of the user's face. In this case, the biometric information acquisition unit 25 or the user information acquisition unit 13 analyzes features such as facial expression, gaze, and pupil size from image data captured by the camera, recognizes emotions, and acquires them as emotional information. Facial expression features may refer to features such as the corners of the mouth and the angle of the corners of the eyes.

[0054] Furthermore, the biometric sensor 30 acquires biometric information of the user for various provided services to be posted. The biometric sensor 30 may acquire common biometric information for various provided services, but may also acquire different types of biometric information depending on the provided service.

[0055] The biosensor 30 is only required to acquire biometric information of the user, and may even execute the process of calculating emotional information of the user from the acquired biometric information, as described above. The information terminal device 2 is not limited to these configurations as long as it is configured to acquire biometric information of the user and transmit that biometric information or emotional information obtained from that biometric information to the server device 1. For example, even if the information terminal device 2 is configured to allow a user of the information terminal device 2 that acquires biometric information to post from another terminal device 2, there is no problem as long as the user and poster are associated.

[0056] (Processing in information processing systems) Next, an example of information transmission processing executed by the information terminal device 2 will be described with reference to Fig. 2. Fig. 2 is a flow chart for explaining an example of such information transmission processing.

[0057] The information transmission process includes a process of acquiring emotional information or the biological information that is the source of the emotional information when using the provided service. Here, an example is given in which the user installs a posting service app on the information terminal device 2 and registers to use the posting service app.

[0058] First, the control unit 20 determines whether the location information acquired by the location information acquisition unit 24 indicates a service provision location where the service is provided (step S101). If the answer is YES in step S101, the control unit 20 determines whether the user has given permission to provide user information including biometric information or emotional information (step S102). Note that if the answer is NO in step S101 or NO in step S102, the process ends.

[0059] In step S101, it can be determined whether the acquired location information matches the location information of a predetermined service providing location within an error range. The location information of the service providing location for each provided service may be preset in the posting service app, or the posting service app may be able to acquire it from the website of each provided service. In step S101, if the location information acquired by location information acquisition unit 24 matches the location information of a certain service providing location within an error range, it can be determined that the user can receive the provided service provided at that service providing location.

[0060] The determination in step S102 can be made by checking the settings of the registered service app. If, during member registration or user registration for the registered service app, the user's permission has been obtained for ascertaining the usage status of the provided services based on the location information of the information terminal device 2 and for acquiring biometric information when using the provided services, then step S102 will be YES. When a user who has registered as a member or user for the posting service app posts a message, that user becomes a poster who has authorized the posting service provider to ascertain the usage status of the provided services and to acquire biometric information when using the provided services.

[0061] The determination in step S101 can also be performed by checking the settings of the registered service app. As described above, the posting service app may allow the user to specify the provided service to be posted, the genre and region of the provided service to which emotional information is to be reflected when posting, etc. In this case, the determination in steps S101 and S102 will be based on this specification. An example of a provided service will be described below: a food and drink service.

[0062] For example, assume that user A has set the provided services to be posted as "food and beverage service > alcoholic beverage service > craft beer." Note that ">" indicates the hierarchy when the provided services are categorized. In this case, if the location information of user A's information terminal device 2 is within the location range indicated by the location information of a food and beverage service store that sells craft beer, the determination of whether the provided service is being used and the acquisition of biometric information are enabled. When the determination of whether the provided service is being used is enabled, the determination of step S101 is executed for the target provided service. When the acquisition of biometric information is enabled, YES is obtained in step S102.

[0063] For example, User B sets the provided service to be posted as "food and drink provision service > alcohol provision," and the provided service to reflect emotional information as "food and drink provision service > alcohol provision > craft beer > Kanagawa Prefecture." In this case, User B can post about alcohol provision services in general, and when the location information of User B's information terminal device 2 is within the location range indicated by the location information of food and drink provision service stores that sell craft beer in Kanagawa Prefecture, the determination of whether the provided service is being used and the acquisition of biometric information are enabled.

[0064] If the answer is YES in step S102, the biometric information acquisition unit 25 acquires user information by, for example, requesting the biometric sensor 30 to acquire biometric information or emotional information, and then instructs the communication control unit 21 to transmit the user information to the server device 1, thereby starting transmission of the user information (step S103).

[0065] Thereafter, the biometric information acquisition unit 25 determines whether the estimated service usage time has elapsed based on the time elapsed from the time when the result of the determination in step S101 was YES to the present and the preset time required to use the provided service (step S104). If the result of the determination in step S104 is YES, the biometric information acquisition unit 25 obtains location information from the location information acquisition unit 24 and determines whether the location information indicates that the user has left the service providing location (step S105). If the result of the determination in step S105 is NO, this determination is repeated until the result of the determination becomes YES. If the result of the determination in step S105 is YES, the biometric information acquisition unit 25 ends the acquisition of user information and transmission to the server device 1 (step S106) and ends the process.

[0066] The estimated service usage time determined in step S104 is set to an appropriate time depending on the content of the service. For example, if an alcoholic beverage is provided in a food and beverage service, the estimated service usage time may be set to an appropriate time depending on the type and location of the store, even if the store provides the same service.

[0067] If the result of step S104 is NO, the biometric information acquisition unit 25 determines whether the location information indicates that the user has left the service providing location (step S107), similarly to step S105. If the result of step S107 is NO, the process returns to step S104. If the result of step S107 is YES, the biometric information acquisition unit 25 determines that the provided service is not being used (step S108), and ends the process.

[0068] Next, an example of a post reflection process executed by the server device 1 will be described with reference to Figs. 3 to 5. Fig. 3 is a flow diagram illustrating an example of a post reflection process executed by the server device 1. Fig. 4 is a schematic diagram showing an example of a post list made public by the server device 1. Fig. 5 is a schematic diagram showing another example of a post list made public by the server device 1.

[0069] First, the posting acceptance unit 12 determines whether or not there has been a posting related to the provided service (step S201). If the result of step S201 is YES, the posting acceptance unit 12 determines whether or not the poster is a user who has used the provided service (step S202). If the result of step S201 is NO, or if the result of step S202 is NO, the processing ends. If the result of step S202 is YES, the posting acceptance unit 12 determines whether or not user information of the poster when using the provided service is stored in the information storage unit 17 (step S203).

[0070] If the answer is YES in step S203, the reflection processing unit 14 reflects the user information in the posted content and displays it (step S204), and ends the process. The display in step S204 can mean storing the posted content in the information storage unit 17 in a state where it can be viewed from an external device via the Internet, etc. If the answer is NO in step S203, the reflection processing unit 14 displays the posted content as is without reflecting the user information (step S205), and ends the process. Note that if the answer is NO in step S203, the posting acceptance unit 12 may further instruct the user information acquisition unit 13 to acquire user information and determine whether or not it has been acquired.

[0071] An example of the display in steps S204 and S205 is given below: A Web page 40 shown in Fig. 4 displays a list of posts about a certain service provided, service C.

[0072] In the post 41 by poster aaaaa, the processing in step S204 displays the post content, as well as the service usage detection date and information detected at the time of use. This example shows a case where user aaaaa, who is using provided service C, has negative emotions, so a comment such as "Let's look forward to the future!" is displayed. In this way, when the obtained emotional information is negative, it is possible to use a roundabout expression rather than expressing it directly. In either case, a viewer who sees post 41 can understand that the positive post content is not very reliable. On the other hand, when user aaaaa, who is using provided service C, has positive emotions, a comment such as "That was a nice restaurant" can be displayed.

[0073] On the other hand, in post 42 by poster bbbbb, only the post content is displayed as a result of the processing in step S205. In post 42, in order to clearly show the difference from post 41, it is also displayed that both the service usage detection date and the information detected at the time of use are undetected, but these displays may be omitted.

[0074] Another example of the display in step S204 is shown below. Web page 50 shown in Fig. 5 displays a list of posts about service C. In the example of Fig. 5, reflection processing unit 14 generates a mark from emotion information or reads a mark corresponding to emotion information and reflects it in the posted content.

[0075] In post 51 by poster ccccc, the processing in step S204 displays the content of the post, as well as the date service usage was detected and the information detected at the time of usage. This example shows that user ccccc was using provided service C and had positive emotions, so five smiley faces are displayed. The more positive the emotions, the more smiley faces there are, or the more smiley faces there are, so the more smiley faces there are. Viewers who see post 51 can understand that the positive content of the post is highly reliable.

[0076] In post 52 by poster ddddd, the processing in step S204 displays the content of the post, as well as the date service usage was detected and the information detected at the time of usage. This example shows a case where user ddddd was using provided service C and had negative emotions, so five angry-looking marks are displayed. The more negative the emotions, the more marks should be increased, or the marks should be changed to show a more negative expression. Viewers who see post 52 can understand that the reliability of the positive content of the post is low.

[0077] 4 and 5 show examples in which the date of service usage detection and information indicating that the information was detected at the time of usage are displayed together, but the date of service usage detection does not have to be displayed. Also, without displaying both pieces of information, emotion information may be displayed as a post indistinguishable from posts accepted by the post accepting unit 12.

[0078] Also, although an example has been given in which the posted content is first made viewable after the reflection processing unit 14 has reflected emotional information in it, the timing at which the posted content is made viewable and the timing at which the emotional information is reflected and made viewable do not have to be the same. For example, a post containing only the user's emotional information may be automatically created and made viewable, and then, if a post is made by that user, the content of that post may be attached. Alternatively, conversely, when a user makes a post, that post may be made viewable for the time being, and then the user's emotional information may be reflected in the post and made viewable later.

[0079] As described above, according to this embodiment, viewers can understand the reliability of the content of posts made about the provided services, such as posts on review sites, and therefore it can be said that the reliability of the content of posts made about the provided services can be improved.

[0080] <Embodiment 2> The information processing system according to the second embodiment will be described with reference to FIGS. 1 to 3, focusing on the differences from the first embodiment, but various examples described in the first embodiment can also be applied.

[0081] The information processing system according to this embodiment differs from that of embodiment 1 in the processing by the determination unit 15 and the reflection processing unit 14 in the server device 1. In this embodiment as well, the user information acquisition unit 13 is configured to acquire from the information terminal device 2 the user's biometric information or emotional information together with the location information at the time the biometric information or emotional information was acquired.

[0082] In this embodiment, the judgment unit 15 is configured to make a judgment for each usage stage of the provided service, and the reflection processing unit 14 is configured to reflect the judgment for each usage stage.

[0083] Specifically, the determination unit 15 in this embodiment not only determines whether a poster who posted a message to a provided service is a user of the provided service, but also determines the usage stage, if applicable. The usage stage can refer to, for example, waiting for usage, in use, or after usage.

[0084] The determination unit 15 can determine whether the user is in a waiting-for-use stage, a using stage, or a post-use stage, based on the location information acquired by the location information acquisition unit 24. The usage stage can be determined from information about the time when the user is using the provided service, information about the location, or the like.

[0085] When determining the usage stage based on location information, for example, if the user's location information is in the center of the range indicating the location where the service is provided, it can be determined that the service is being used, and if the location information is on the outer edge of the range indicating the location where the service is provided, it can be determined that the service has not yet been used. For example, in the case of a food and beverage service, the center of the range indicating the location where the service is provided can refer to the location where the tables are located. Furthermore, if the facility has a separate waiting room, the location information of the waiting room can also be used to make the determination.

[0086] When determining the usage stage based on time information, for example, the typical waiting time from the time when the user's location information enters the range indicating the location where the provided service is provided until the user receives the provided service, or the waiting time reflecting congestion at that time, etc., is determined to be before service use.

[0087] The reflection processing unit 14 in this embodiment reflects emotion information acquired by the user information acquisition unit 13 according to the usage stage of the provided service to the post accepted by the post accepting unit 12. In other words, the reflection processing unit 14 reflects emotion information for each usage stage acquired by the user information acquisition unit 13 for the provided service to the post accepted by the post accepting unit 12. The reflection method may be, for example, to reflect emotions for each usage stage, such as emotions before use, emotions during use, and emotions after use, or to reflect changes in emotions according to the usage stage as a single emotion.

[0088] As an example, consider a case where the user information acquisition unit 13 acquires information from the location information and time information of the information terminal device 2 that user eeeee stayed at food and beverage facility E from 18:00 to 19:30 on September 3, 2024. In this example, the determination unit 15 can determine, based on congestion information for that day, for example, that the waiting time to use the facility is from 18:00 to 18:20, the period during use is from 18:20 to 19:30, and the period after use is from 19:30 for approximately 30 minutes.

[0089] Then, when the user information acquisition unit 13 acquires emotion information indicating positive emotions, for example, while waiting to use the store, during use, or after use, the reflection processing unit 14 reflects a comment such as "It was a nice store" in the content posted by user eeeee.

[0090] Furthermore, if the user information acquisition unit 13 acquires emotion information that indicates negative emotions during the waiting time for use and positive emotions during and after use, the reflection processing unit 14 reflects a comment such as "How was the waiting time?" in the content posted by user eeeee.

[0091] Furthermore, if the user information acquisition unit 13 acquires emotion information indicating negative emotions, for example, while waiting for use, during use, or after use, the reflection processing unit 14 reflects a comment such as "Let's look forward to the future!" in the content posted by user eeeee.

[0092] In either example, the viewer can learn more about the actual situation by displaying emotional information in the form of a repost by the user eeeee of the content posted by the user, or by displaying the content posted by the user in the form of a repost by the user of eeeee's emotional information. Furthermore, even if only the emotional information of user eeeee is displayed for viewing, the viewer can learn information that will be helpful in deciding whether to use the provided service, such as its advantages or disadvantages.

[0093] Although a detailed description of the flow of the information transmission process and the post reflection process in this embodiment will be omitted, the process is outlined as follows. In the information transmission process, in step S103 during the process of FIG. 2, when acquiring user information by, for example, requesting the biometric sensor 30 to acquire biometric information or emotional information, the biometric information acquisition unit 25 also causes the location information acquisition unit 24 to acquire location information. Then, when transmitting the biometric information or emotional information to the server device 1, it is preferable to transmit the location information together with the biometric information or emotional information. This allows the user information acquisition unit 13 to acquire the user's biometric information or emotional information from the information terminal device 2, including location information indicating the latitude and longitude at the time the biometric information or emotional information was acquired. In the post reflection process, in step S204 during the process of FIG. 3, it is preferable to reflect user information according to the usage stage in the posted content and display it.

[0094] According to this embodiment, emotion information that takes into consideration the use stage of the provided service can be obtained, and therefore the reliability of posts can be further improved compared to the first embodiment.

[0095] <Alternative examples, etc.> Some or all of the processing in the server device 1 or the information terminal device 2 described above can be implemented as a computer program. The program includes a set of instructions (or software code) that, when loaded into a computer, causes the computer to perform one or more functions described in the embodiments. The program may be stored in a non-transitory computer-readable medium or a tangible storage medium. By way of example and not limitation, computer-readable media or tangible storage media include random-access memory (RAM), read-only memory (ROM), flash memory, solid-state drive (SSD) or other memory technology, CD-ROM, digital versatile disc (DVD), Blu-ray (registered trademark) disc or other optical disk storage, magnetic cassette, magnetic tape, magnetic disk storage or other magnetic storage device. The program may also be transmitted on a transitory computer-readable medium or communication medium. By way of example and not limitation, transitory computer-readable media or communication media include electrical, optical, acoustic, or other forms of propagated signals.

[0096] The present disclosure is not limited to the above-described embodiments and can be modified as appropriate without departing from the spirit of the present disclosure. For example, the biometric information and emotional information described above can be information other than the exemplified information, and the method of reflecting the information in posts is not limited to the exemplified information. Furthermore, the services provided are not limited to the exemplified information. [Explanation of symbols]
