[Conversion server]
The conversion server 80 includes, for example, a conversion side interface 82, a conversion request unit 84, and a registration unit 86. The conversion side interface 82 acquires the user position information output to the second interface 78. The conversion request unit 84 requests the response server 90 to reduce the particle size of the position information of the user position information acquired by the conversion side interface 82, and acquires the processing result in response to the request from the response server 90. The conversion request unit 84 requests, for example, the response server 90 to convert the position information of the user position information into categories. The classification is a classification such as a city, ward, town, or village corresponding to location information. The registration unit 86 stores the converted user position information (an example of the “first database”) in which the processing result (for example, classification) of the response server 90 and the user ID are associated with each other in the position information storage device 100.

The response server 90 reduces the particle size of the position information in response to the request. For example, the response server 90 identifies a category corresponding to the location information, and returns the specified category to the conversion server 80.

Returning to the description of FIG. The position information storage device 100 stores, for example, the converted user position information transmitted by the conversion server 80. The position information storage device 100 includes a storage unit that stores information such as an HDD (Hard Disk Drive) and a processing unit that is realized by a hardware processor such as a CPU executing a program stored in the storage unit.

Remember. In response to the request from the extraction server 120, the permission information storage device 110 extracts the permission presence / absence information associated with the user ID included in the request, and transmits the extraction result to the extraction server 120.

The extraction server 120 includes, for example, an acquisition unit 122 and a processing unit 124. The acquisition unit 122 and the processing unit 124 are realized by a hardware processor such as a CPU executing a program stored in a storage device.

The first acquisition unit 152, the second acquisition unit 154, and the first supply unit 156 are realized by a hardware processor such as a CPU executing a program stored in a storage device.

The first acquisition unit 152 acquires specific information including a specific event and position information corresponding to the specific event. The second acquisition unit 154 acquires information about the user transmitted by the API providing server 140. The information about the user is the information of the user associated with the classification of the location information included in the permission information and the specific information. The first providing unit 156 provides specific information to the terminal device of the user having the user ID included in the information about the user acquired by the second acquisition unit 154.

The second providing server 160 includes, for example, a third acquisition unit 162, a fourth acquisition unit 164, and a second providing unit 166. The third acquisition unit 162, the fourth acquisition unit 164, and the second supply unit 166 are realized by a hardware processor such as a CPU executing a program stored in the storage device.

The third acquisition unit 162 acquires the request information in which the user ID and the transmission request of the specific event are associated with each other from the terminal device 10. The fourth acquisition unit 164 acquires the position information associated with the user ID acquired by the third acquisition unit 162 from the position information storage device 100. The second providing unit 166 provides the user's terminal device 10 with information regarding a specific event associated with the position information acquired by the fourth acquisition unit 164.

[Terminal device]
FIG. 3 is a diagram showing an example of the functional configuration of the terminal device 10. The terminal device 10 is a portable device used by a user, and is, for example, a mobile phone such as a smartphone, a tablet computer, a notebook computer, or the like. The terminal device 10 includes, for example, a communication unit 12, a positioning unit 14, a terminal control unit 16, a transmission control unit 20, and a storage unit 30.

The terminal control unit 16 and the transmission control unit 20 are realized by a hardware processor such as a CPU executing a service application (software) 32 stored in the storage unit 30. These functional units may be realized by hardware such as LSI, ASIC, FPGA, GPU, or may be realized by the cooperation of software and hardware (including circuit unit; circuitry). The storage unit 30 is realized by, for example, a ROM, a flash memory, an SD card, a RAM, a register, or the like.

In the storage unit 30, for example, the user ID, the service application 32 described above, the public key information 34, and the position information 36 positioned by the position positioning unit 14 described later are stored. The position information 36 is information in which the measured time and the latitude / longitude are associated with each other. The public key information 34 is information acquired by the terminal control unit 16 from another server.

The communication unit 12 includes a communication interface such as a wireless communication module. The communication unit 12 performs wireless communication, connects to the network NW, and communicates with another device via the network NW.

The positioning unit 14 includes a GPS (Global Positioning System) receiver. The positioning unit 14 performs positioning based on the radio wave received from the satellite by the GPS receiver, and identifies the position of the terminal device 10 (that is, the position of the user). Further, the terminal device 10 may estimate the position of the terminal device 10 from the position of the radio base station to which the communication unit 12 is connected.

For example, the terminal control unit 16 stores the position information measured by the position positioning unit 14 in the storage unit 30 as the position information 36 in association with the positioning time. Further, the terminal control unit 16 includes, for example, a cryptographic processing unit 18. The encryption processing unit 18 encrypts the location information 36 using the public key information 34.

The transmission control unit 20 uses the communication unit 12 to transmit information in which the encrypted position information 36 and the user ID are associated with each other to the front-end server 50.

[Processing of terminal device]
FIG. 4 is a flowchart showing a flow of processing executed by the terminal device 10. Next, the terminal control unit 16 determines whether or not the service application 32 has been activated (S10). When the service application 32 is activated, the terminal control unit 16 acquires public key information from a predetermined server (S12). The public key information 34 may be acquired in advance.

Next, the terminal control unit 16 inquires whether or not the user is permitted to transmit the position information, and determines whether or not the user is permitted to transmit the position information (S14). For example, the terminal control unit 16 causes the display unit (output unit) of the terminal device 10 to display an image inquiring whether or not the transmission of the position information 36 is permitted, and when the user performs an operation permitted, the terminal control unit 16 permits the transmission. Is determined. In addition, instead of the display unit, a voice inquired by a speaker (output unit) or the like may be output. In this case, the terminal device 10 recognizes the voice input to the microphone and determines whether or not it is permitted based on the recognition result.

If the user does not allow the transmission of location information, the processing of this flowchart ends. When the transmission of the location information is permitted by the user, the transmission control unit 20 transmits the permission information to the front-end server 50 (S16). This permission information is stored in the permission information storage device 110 via, for example, the front-end server 50.

The terminal control unit 16 causes the position positioning unit 14 to perform positioning (S18), and encrypts the positioned position information (S20). Next, the terminal control unit 16 transmits the user position information including the encrypted position information to the front-end server 50 (S22). Next, the terminal control unit 16 determines whether or not the end condition is satisfied (S24). The termination condition is, for example, that the permission for transmitting the location information has been revoked by the user. This ends the processing of one routine in this flowchart.

The location information may be transmitted only when the service application 32 is running, or may be performed by background processing even when the service application 32 is not running.

Further, the terminal device 10 may transmit the setting category to the front-end server 50 by the operation of the user. The setting category is a category in which the user receives information about the category (region). As will be described later, the setting category is stored in association with the user ID in the position information storage device 100 in the same manner as the position information.

[Processing of decryption server, conversion server, etc.]
FIG. 5 is a diagram (No. 1) for explaining the processing of the decoding server 70, the conversion server 80, and the like. The decryption server 70 decodes the user position information acquired from the position information collection server 60 by using the private key information 77. The decoding server 70 reduces the particle size of the decoded position information, and transmits the position information with the reduced particle size to the conversion server 80 (S100). The decoding server 70, for example, truncates the number after the decimal point n of the latitude and longitude, which is the position information. "N" is an arbitrary natural number. As a result, position information that is easy to handle in the subsequent processing is generated. The latitude / longitude with the number after the decimal point n rounded down is an example of the position information of the "second particle size".

Next, the conversion server 80 acquires the normalized position information and requests the response server 90 to perform a process of converting the acquired position information into categories (S102). Correspondence information 92 is stored in the storage device of the response server 90. The correspondence information 92 is information in which the classification and the position information (latitude / longitude) are associated with each other. The response server 90 converts the acquired position information into a category with reference to the correspondence information 92, and returns the converted category to the conversion server 80 (S104). The classification is an example of the position information of the "third particle size". Next, the conversion server 80 stores the user position information in which the division returned by the response server 90 and the user ID are attached to each other in the position information storage device 100 (S106).

FIG. 6 is a diagram (No. 2) for explaining the processing of the decoding server 70, the conversion server 80, and the like. For example, as shown in FIG. 5, the decoded position information, which is the latitude and longitude, is truncated after the decimal point n. Latitudes and longitudes rounded down to the second decimal place are converted into divisions. Then, the converted division is associated with the user ID and stored in the position information storage device 100.

As described above, in the restricted communication environment, the confidentiality of the location information is maintained because the decryption and the reduction of the particle size are performed as described above. The particle size of the position information is lowered in the decoding server 70, and the particle size of the position information whose grain size is lowered is further lowered in the conversion server 80. By performing the process of lowering the particle size in two steps in this way, the confidentiality of the decoded position information is maintained. Further, since the position information is converted into categories and the converted position information is used in the subsequent processing, the position information is handled so that the detailed action history of the user cannot be specified.

[Processing of extraction server, etc.]
FIG. 7 is a diagram (No. 1) for explaining the processing of the extraction server 120 and the like. The extraction server 120 acquires the converted user position information from the position information storage device 100 (S200). The acquired user location information is, for example, information indicating the latest classification. Next, the extraction server 120 acquires permission presence / absence information from the permission information storage device 110 (S202). Next, the extraction server 120 processes the information acquired in S200 and S202 as described later and stores it in the extraction information storage device 130 (S204).

FIG. 8 is a diagram (No. 2) for explaining the processing of the extraction server 120 and the like. The extraction server 120 acquires the user ID and the classification (hereinafter referred to as the positioning classification) in which the latitude and longitude are converted by the conversion server 80 from the user position information stored in the position information storage device 100, and further, the permission information storage device 110. The permission presence / absence information associated with the user ID is acquired from. Then, the extraction server 120 uses the positioning category as a key to generate information in which the user ID corresponding to the positioning category and the permission presence / absence information corresponding to the user ID are associated with the positioning category. As shown in the left figure of FIG. 8, the information (an example of the “third database”) using the generated positioning category as a key is stored in the extraction information storage device 130. In this way, information that is easy to use in the subsequent processing is generated.

Further, the extraction server 120 acquires the setting category and the user ID stored in the location information storage device 100, and further acquires the permission presence / absence information of the user ID from the permission information storage device 110. Then, the extraction server 120 uses the setting category as a key to generate information in which the user ID corresponding to the setting category and the permission presence / absence information corresponding to the user ID are associated with the setting category. As shown in the right figure of FIG. 8, the information (an example of the “third database”) using the generated setting category as a key is stored in the extraction information storage device 130. In this way, information that is easy to use in the subsequent processing is generated.

As shown in FIG. 8, the combination of the positioning category, the user ID, and the permission / non-existence information, or the combination of the setting category, the user ID, and the permission / non-permission information may be referred to as a “record”.

[Processing of the first provider server, etc.]
FIG. 9 is a diagram (No. 1) for explaining the processing of the first providing server 150 and the like. The first providing server 150 acquires specific information and a classification corresponding to the specific information from a predetermined information providing server (S300). The specific information is information indicating that a specific event has occurred. Specific events are, for example, events that should be known to users regarding weather, disasters, delays in transportation, and the like. The category corresponding to the specific information is the category that is expected to be affected by the specific event.

Next, the first providing server 150 requests the API providing server 140 to transmit information regarding the classification corresponding to the specific information (S302). Next, the API providing server 140 transmits the request transmitted by the first providing server 150 to the extraction information storage device 130 (S304). Next, the extraction information storage device 130 extracts a record associated with the category included in the request in response to the request of S304, and transmits the extracted record to the API providing server 140 (S306).

Next, the API providing server 140 acquires the record extracted from the extraction information storage device 130, and transmits the acquired record to the first providing server 150 (S308). At this time, the API providing server 140 transmits the user information (record) to which the permission information is associated among the acquired records to the first providing server 150. Next, the first providing server 150 transmits information based on the specific information to the terminal device 10 of the user ID included in the transmitted record (S310). Details will be described later with reference to FIG.

FIG. 10 is a diagram (No. 2) for explaining the processing of the first providing server 150 and the like. For example, the first providing server 150 acquires, as specific information, information indicating that it is raining heavily in the category "001" (S300). Then, the API providing server 140 acquires the category "001" from the first providing server 150, and requests the extraction information storage device 130 to return the record whose positioning category or setting category is "001" (S304). ..

The extraction information storage device 130 extracts the record of the positioning category or the setting category "001" in response to the request transmitted by the API providing server 140, and transmits the extracted record to the API providing server 140 (S306). Then, the first providing server 150 transmits the specific information to the terminal device 10 of the user ID included in the extracted record.

As described above, the first providing server 150 provides information to the user who is authorized to use the location information. After the terminal device 10 last transmits the position information, the last transmitted position information is held in the position information storage device 100 for a predetermined period, and specific information regarding the position information is provided to the user. When the terminal device 10 transmits the location information, it is transmitted after obtaining the permission of the user. For example, if the user disallows the use of the location information within a predetermined period after the permission, the permission information is stored. If the information is provided to the user without considering the permission information of the device 110, the information may be provided to the disapproved user. Therefore, the first providing server 150 suppresses the provision of information to the unauthorized user by providing the information to the user who is permitted to use the location information in the permission information storage device 110. Can be done.

Further, the extraction server 120 processes the information stored in the position information storage device 100 and the permission information storage device 110, and stores the processed information (information using the division as a key) in the extraction information storage device 130. The extraction information storage device 130 can quickly extract information corresponding to a predetermined category from the processed information and provide the extracted information to the API providing server 140. For example, it may take a predetermined time or more for the position information storage device 100 to extract information corresponding to a predetermined category from the stored information. Further, it may take a predetermined time or more for the permission information storage device 110 to extract information of a plurality of designated users from the stored information.

On the other hand, in the present embodiment, the information is processed in advance in the extraction information storage device 130 so that the information in which the user ID corresponding to the predetermined category and the permission presence / absence information are associated with each other can be quickly extracted. The processed information is stored. Therefore, the extraction information storage device 130 can quickly extract the information corresponding to the predetermined category in a time shorter than the above-mentioned predetermined time, and provide the extracted information to the API providing server 140. As a result, the first providing server 150 can quickly provide information requiring urgency such as a disaster to a predetermined user.

FIG. 11 is a diagram showing an example of a scene in which specific information is provided to the terminal device 10. For example, when heavy rain occurs in the category "001", the first providing server 150 may be used, for example, in the terminal device 10 of the user ID of the positioning category "001" and the terminal device 10 of the user ID of the setting category "001". Provide information indicating that you should be careful of heavy rain.

As described above, the user can acquire specific information without searching for the information or requesting the information by himself / herself. As a result, the user can quickly obtain useful information.

[Processing of the second provider server, etc.]
FIG. 12 is a diagram (No. 1) for explaining the processing of the second providing server 160 and the like. First, the second providing server 160 acquires a request for information about the current location of the terminal device 10 and a user ID from the terminal device 10 (S400). Next, the second providing server 160 transmits the acquired information request regarding the current location and the user ID to the API providing server 140 (S402).

Next, the API providing server 140 transmits the user ID to the position information storage device 100, and requests transmission of the positioning category associated with the user ID (S404). Next, the position information storage device 100 extracts the positioning category corresponding to the user ID in response to the request of S404, and transmits the extracted positioning category to the API providing server 140 (S406).

Next, the API providing server 140 requests the permission information storage device 110 to transmit the permission presence / absence information corresponding to the user ID (S408). Next, the permission information storage device 110 extracts the permission / non-existence information corresponding to the user ID in response to the request, and transmits the extracted permission / non-existence information to the API providing server 140 (S410).

Next, the API providing server 140 transmits the positioning classification and permission presence / absence information transmitted in S406 and S410 to the second providing server 160 (S412). At this time, if the permission information is not associated with the user ID of the user who sent the request for the information about the current location, the API providing server 140 may transmit the information to that effect to the second providing server 160. .. In this case, the second providing server 160 may ask the user for permission to use the location information. Further, since the user is sending the request, the confirmation of the permission presence / absence information may be omitted.

Next, the second providing server 160 accesses a predetermined information providing server, acquires information indicating whether or not a specific event has occurred in the positioning category transmitted in S406, and outputs information based on the acquisition result to the terminal. It is transmitted to the device 10 (S414).

FIG. 13 is a diagram (No. 2) for explaining the processing of the second providing server 160 and the like. For example, when the terminal device 10 requests the second providing server 160 to send information about the current location, the second providing server 160 performs the above-mentioned processing, and if a specific event occurs, it is specified as shown in the figure. The transmission of information about the event is transmitted to the terminal device 10. If the specific event does not occur, information indicating that the specific event has not occurred is transmitted to the terminal device 10.

In the above example, the information regarding the specific event of the positioning category has been described as being transmitted to the terminal device 10, but instead (or in addition), the information regarding the specific event of the setting category is transmitted to the terminal device 10. You may.

By the process described above, the information providing system 1 provides the user with information on a specific event at the user's current location or a set position in response to the user's request. As a result, the user can obtain useful information.

According to the first embodiment described above, the decryption server 70 acquires the user position information in which the user ID and the encrypted position information are associated with each other from the terminal device, decodes the acquired position information, and decodes the acquired position information. Performs processing to reduce the granularity of the decoded position information. As a result, information can be managed more strictly. Further, the information providing system 1 can more quickly transmit useful information to the terminal device 10 based on the user's location information.

<Modified example of the first embodiment>
Hereinafter, a modified example of the first embodiment will be described. The modified decoding server 70 of the first embodiment communicates with the location information collection server 60 or the conversion server 80 via a network accessible to other devices instead of a dedicated line. Hereinafter, the differences from the first embodiment will be mainly described.

FIG. 14 is a functional configuration diagram centered on the decoding server 70 of the information providing system 1 of the modified example of the first embodiment. For example, the location information collection server 60, the decryption server 70, and the conversion server 80 communicate with each other via the network NW1. The network NW1 is a network that can be accessed by devices other than the location information collection server 60 such as WAN and LAN (Local Area Network), the decoding server 70, and the conversion server 80.

The first interface 72 communicates only with the location information collection server 60 via the network NW1 and acquires the location information transmitted by the location information collection server 60. The second interface 78 communicates only with the conversion server 80 via the network NW1 and outputs the decoded position information to the conversion server 80.

According to the information providing system 1 of the modified example of the first embodiment described above, the same effect as the effect of the first embodiment can be obtained.

<Second Embodiment>
Hereinafter, the second embodiment will be described. In the second embodiment, the analysis server analyzes the location information and estimates the user's behavior. Hereinafter, the differences from the first embodiment will be described.

FIG. 15 is a diagram showing an example of the functional configuration of the information providing system 1A. The information providing system 1A includes, for example, one or more terminal devices 10, a front-end server 50, a position information collection server 60, a decoding server 70, a position information storage device 100, an analysis server 200, and an analysis information storage device. It includes 210 and a third providing server 220.

The decoding server 70 communicates with the location information collection server 60 or the location information storage device 100 via a LAN, a dedicated line, or the like. The decryption server 70 can communicate only with, for example, the location information collection server 60 or the location information storage device 100.

The analysis server 200 analyzes the position information for each user stored in the position information storage device 100, and estimates the user's behavior, the facility used, and the like based on the analysis result. For example, the analysis server 200 estimates the user's home or workplace, commuting route, facilities often visited on weekends, etc. based on the location information history.

FIG. 16 is a diagram showing the distribution of location information and the estimated home and work. For example, the analysis server 200 identifies a user's position in a predetermined time zone at night, and if the same position information exists in a predetermined number or more in that time zone in a week, the analysis server 200 estimates the position as home. Further, for example, the analysis server 200 specifies the position of the user in a predetermined time zone in the daytime, and if the same position information exists in the predetermined number or more in the time zone in a week, the position is estimated as the workplace. Based on the processing equivalent to the above-mentioned processing, the analysis server 200 estimates the commuting route from the home to the workplace, the facility to be used, and the like. Further, the analysis server 200 estimates the transportation system to be used based on the commuting route. The method for specifying the home or the workplace is not limited to the above method, and various known methods may be used or may be given in advance.

The analysis information storage device 210 stores the analysis results of the analysis server 200 for each user. For example, a predetermined user uses XX station, uses line A, and stores information such as going to work.

The third providing server 220 provides specific information to the user's terminal device 10 based on the information stored in the analysis information storage device 210 and the specific information acquired from the information providing server (not shown). For example, when the third providing server 220 acquires information indicating that the A route is delayed as specific information, it means that the A route is delayed before the predetermined time when the predetermined user leaves the home. The indicated information is transmitted to the terminal device 10 of a predetermined user. The information provided to the user by the third providing server 220 is not limited to the specific information, but may be other information. Other information is, for example, information that the user may be interested in, such as information on recommended restaurants at stations used for commuting, coupons for restaurants, and information on places where users often go (for example). , Movie theater screening schedule).

According to the second embodiment described above, the analysis server 200 analyzes the position information history. Then, the third providing server 220 can provide the user with information useful to the user based on the analysis result.

<Third Embodiment>
Hereinafter, the third embodiment will be described. The information providing system of the third embodiment includes a learning processing device. This learning processing device uses position history information and the like to generate a trained model that estimates the user's behavior, and uses the trained model to estimate the user's behavior. Hereinafter, the differences from the first embodiment or the second embodiment will be described.

FIG. 17 is a diagram showing an example of the functional configuration of the learning processing device 300. The learning processing device 300 includes, for example, a fifth acquisition unit 302, a sixth acquisition unit 304, a route derivation unit 306, an information providing unit 308, a learning unit 310, and a storage unit 320.

In the fifth acquisition unit 302, the sixth acquisition unit 304, the route derivation unit 306, the information providing unit 308, and the learning unit 310, for example, a hardware processor such as a CPU stores a program (software) stored in the storage unit 320. It is realized by executing. These functional units may be realized by hardware such as LSI, ASIC, FPGA, GPU, or may be realized by the cooperation of software and hardware. The storage unit 30 is realized by, for example, a ROM, a flash memory, an SD card, a RAM, an HDD, a register, or the like. The storage unit 320 stores the training data 322, the trained model 324, and the position information 326. The position information 326 is information indicating the position information history for each user.

The fifth acquisition unit 302 acquires the learning data 322 from another server and stores it in the storage unit 320. The learning data 322 is the user's position information and the transportation information used by the user associated with the position information. For example, the learning data 322 is information in which information such as a train line used or a bus line is associated with a predetermined position information history.

The sixth acquisition unit 304 acquires the information transmitted by the terminal device 10 directly or via another device.

The route derivation unit 306 derives a route estimated to be used by the user based on the learned model 324 generated by the learning unit 310 described later and the user's position information 326.

The information providing unit 308 provides the user's terminal device 10 with information on the route derived by the route deriving unit 306.

The learning unit 310 uses the learning data 322 to generate a trained model 324. The learning unit 310 machine-learns the learning data 322 to generate a trained model 324.

[Flowchart (1)]
FIG. 18 is a flowchart showing an example of the flow of processing executed by the learning unit 310. First, the learning unit 310 acquires learning data 322 including information in which the location information history and the usage route are associated with each other (S500). The route used is teacher data. Next, the learning unit 310 machine-learns the learning data acquired in S500 (S502) and generates a trained model 324 (S504). For example, the learning unit 310 applies the training data to a model such as a neural network and adjusts the parameters of the model to generate a trained model 324. This ends the processing of one routine in this flowchart.

[Flowchart (Part 2)]
FIG. 19 is a flowchart showing an example of the flow of processing executed by the terminal device 10 and the learning processing device 300. First, the terminal device 10 determines whether or not the user has activated the service application 32 (S600). When the user activates the service application 32, the terminal device 10 transmits information indicating that the service application 32 has been activated and the user ID to the learning processing device 300 based on the processing by the service application 32 (S602). Subsequent processing of the terminal device 10 is, for example, processing performed by executing the service application 32.

Next, the sixth acquisition unit 304 of the learning processing device 300 acquires the information transmitted in S602, and acquires the position information history corresponding to the acquired user ID from the position information 326 (S700). Next, the route derivation unit 306 inputs the position information history to the trained model 324, and derives a route presumed to be used by the user based on the result output by the trained model 324 (S702). Next, the information providing unit 308 transmits the route derived in S702 to the user's terminal device 10 (S704).

Next, the terminal device 10 asks the user whether to use the route estimated by the learning processing device 300 (S604). The inquiry means, for example, that the terminal device 10 causes the display unit to display information inquiring whether or not to use the route. In response to the inquired information, the user performs an operation indicating that the estimated route is used or an operation indicating that the estimated route is not used.

When an operation indicating that the user does not use the estimated route is performed, the terminal device 10 performs a predetermined process (S606). The predetermined process is, for example, a process in which the terminal device 10 requests the learning processing device 300 to propose a route other than the above-estimated route. In this case, the learning processing device 300 transmits information on routes other than the above routes to the terminal device 10. The terminal device 10 asks the user whether to use a route other than the above route. Further, the predetermined process is, for example, a process in which the terminal device 10 presents the list information of the route to the user and causes the user to select a route from the list information.

Next, the terminal device 10 transmits information based on the above-mentioned user operation result (for example, the route to be used) to the learning processing device 300 (S608). Next, the sixth acquisition unit 304 of the learning processing device 300 acquires the information transmitted in S608, and stores the acquired information in the storage unit 320 (S706). Next, the sixth acquisition unit 304 stores, for example, information on the route used by the user in association with the user ID (S708). Thereby, the information providing system 1B can provide the user with information about the route used by the user. The information about the route used by the user is information about the delay of the route, information about restaurants and stores along the route, and the like.

Further, the sixth acquisition unit 304 generates learning data 322 in which the user's position information history and the transmitted route information are associated with each other. The transmitted route information is an example of teacher data. The generated training data 322 is data used for generating the trained model 324 and updating the trained model 324. As a result, the learning processing device 300 can generate the trained model 324 that derives the user's usage route more accurately.

FIG. 20 is a diagram showing an example of how the information providing system 1B of the third embodiment provides information to the terminal device 10. After the service application 32 of the terminal device 10 is activated, the route information estimated by the learning processing device 300 is displayed on the display unit of the terminal device 10. When the user performs an operation indicating that the estimated route is used, for example, the operation result is transmitted to the learning processing device 300. When the learning processing device 300 acquires the operation result, for example, the learning processing device 300 instructs the second providing server 160 to provide the user with information regarding the user's route of use. Then, the second providing server 160 acquires, for example, information about the A route from another server, and transmits the information based on the acquired information to the terminal device 10. For example, when there is a delay on the A route, information indicating that the delay has occurred is transmitted to the terminal device 10. As described above, the user can easily obtain the information he / she wants to obtain.

According to the third embodiment described above, the learning processing device 300 provides the user with the behavior of the user estimated by using the position information history and the learned model 324, and acquires the response result of the user to the provision result. .. Then, the learning processing device 300 is used for selecting information to be provided to the user. As a result, the information providing system 1B can provide useful information to the user without imposing a load on the user. Further, by using the above response result for the generation or update of the trained model 324, it is possible to contribute to the generation of the trained model 324 that can estimate the user's behavior more accurately.

According to the embodiment described above, the information providing system 1 is stored in the position information storage device 100 that stores the first database for providing the position information transmitted by the terminal device 10 to the user who is the information user.
