Description

  The present invention belongs to the information communication field, and for example, maintains and manages attribute information of a user of the mobile communication terminal by using probe information including current position information transmitted from a mobile communication terminal such as a mobile phone terminal. The present invention relates to an apparatus, a method, and a system.

  Various mobile phone terminals equipped with a GPS (Global Positioning System) module and capable of positioning their current position have been provided. Accordingly, as disclosed in Patent Document 1 described later, according to the current position of the user measured by the mobile phone terminal and the attribute information of the user, guidance information and the like according to the user are provided. Services are becoming available. For example, when a user is in the vicinity of Shibuya Station, a service is provided in which guidance information about stores near Shibuya Station is automatically provided to the user's mobile communication terminal.

  In the case of the invention described in Patent Document 1, it is important to register personal attribute information in advance for each user. This is because if there is no personal attribute information, for example, there is a possibility that the provision of alcoholic beverages to minors may provide inappropriate information such as providing main store information. However, in order to prepare personal attribute information for each user in advance, first, accurate attribute information must be provided from each user, and this must be compiled into a database, which requires complicated work.

  Therefore, Patent Document 2 described later discloses an invention that allows user attribute information to be specified and stored without performing any special work. The invention described in Patent Document 2 receives the provision of probe information including the current position information of the mobile phone terminal from the mobile phone terminal at every predetermined timing, and analyzes the probe information to obtain user attributes. Information is identified and stored.

  User attribute information includes fixed information such as name, date of birth, telephone number, and e-mail address, as well as current address, family structure, occupation, etc. (different occupations, students, etc.), workplace ( Non-fixed information such as the location of work or school), income, hobbies, stopovers, and other information. Among the attribute information, since the fixed information is information that is always required when contracting with a telephone company, for example, the collection and registration can be performed relatively easily.

  However, some non-fixed information is not essential information at the time of a contract with a telephone company, and the contents vary widely for each user, so that collection and registration takes time. However, by using the invention described in Patent Document 2, non-fixed attribute information in the attribute information is also managed on the user side of the mobile phone terminal at the time of making a database. The telephone company does not need to perform complicated work.

  The invention described in Patent Document 2 described above is very effective because the attribute information of the user of the mobile phone terminal can be specified and stored without performing complicated work. However, it is difficult to identify and store truly accurate attribute information, and to properly maintain and manage it. For example, it is assumed that the place where the user stays from the night to the morning of the next day can be identified by analyzing the probe information from the mobile phone terminals provided sequentially for a predetermined period. In this case, even if the stay location is taken into consideration, it may not be possible to appropriately determine whether the location is at home or a business trip or travel destination.

  Further, it is assumed that the number of people staying at the same place (for example, the same detached house) at night is detected by analyzing the probe information of a plurality of users for a predetermined period. In this case, for example, it is difficult to determine whether the number of family members living together has increased due to marriage or the like, or whether friends or acquaintances have stayed for a relatively long period of time due to some business. Thus, even if the attribute information of the user of the mobile phone terminal can be detected by analyzing the probe information from the mobile phone terminal, it cannot be determined whether or not the attribute information is truly correct. . Further, among the attribute information, it is difficult to properly maintain and manage the attribute information because the above-mentioned non-fixed information is unknown.

  Also, consider using personal attribute information from another perspective. Various attribute information such as the user's name, address, age, and gender is not only for users who want to keep everything secret, but if there is some merit, I think that it can be disclosed to some extent There are many users. In recent years, it has a mechanism that allows you to register personal attribute information in advance, answer questionnaires, participate in campaigns, receive points, collect them, and exchange the points you earn for cash or prizes There are quite a few sites.

  However, personal attribute information required by companies for market research and product advertisement is highly reliable information. For this reason, even if there is attribute information of an individual authorized by the user to be disclosed, it becomes information that has little meaning for companies unless it is properly updated and accurate. As in the point providing site described above, even if personal attribute information is collected, there is no method for appropriately updating the attribute information. In addition, the conventional method of investigating personal attribute information by telephone or visit takes time and expense, and the survey results may only be used at that time, so accurate and accurate personal attribute information can be obtained continuously. There are also requests to get.

  In view of the above, it is an object of the present invention to appropriately maintain and manage personal attribute information about a large number of users without using time and effort, and to use it as accurate information. To do.

In order to solve the above problem, the attribute information management server according to the first aspect of the present invention provides:
Probe information that is transmitted from the user's mobile communication terminal at a predetermined timing and includes identification information that can identify the user , date and time information at the time of transmission, and position information at the time of transmission Receiving means for
For each user of the mobile communication terminal, attribute information holding means for storing and holding personal attribute information including attribute information that can be estimated whether or not the probe information has been changed by analyzing the probe information ;
Probe information storage means for storing probe information received by the receiving means for each user;
Whether the probe information stored in the probe information storage unit is analyzed for each user, and whether or not the probe information is changed by analyzing the probe information among the attribute information of the user held in the attribute information holding unit An estimation means for estimating whether or not a change has occurred in the attribute information that can be estimated,
For the user who is inferred that the attribute information has changed by the estimation means, the content of the attribute information after the change obtained by estimation is shown to the user, and an inquiry is made as to whether or not the attribute information has changed. Inquiry means ;
The reliability level of the attribute information is set based on the result of the inquiry using the inquiry unit, and the attribute information estimated to be unchanged by the estimation unit is evaluated for reliability. And an evaluation level setting means for setting the level high .

According to the attribute information management server of the first aspect of the present invention, the attribute information holding means includes the attribute information that can be inferred whether or not the information has been changed by analyzing the probe information for each user of the mobile communication terminal. Individual attribute information is stored and held in advance. Probe information including identification information that can identify the user from the mobile communication terminal , date and time information at the time of transmission, and position information at the time of transmission is sequentially received by the receiving means, and this is received by the probe information accumulating means. Accumulated. Then, the probe information accumulated in the probe information accumulation means is analyzed for each user by the estimation means, and it is estimated whether or not the analysis has been performed by analyzing the probe information of the user held in the attribute information holding means. It is estimated whether or not the attribute information that can be changed has occurred.

When it is inferred that the attribute information that can be inferred by analyzing the probe information has been changed by the inferring means, the user of the attribute information that is inferred to have changed, through the inquiry means, The content of the changed attribute information obtained by estimation is shown to the user, and an inquiry is made as to whether or not the attribute information has changed. That is, whether the attribute information has changed permanently (whether it has really changed) or whether it is a temporary change and not a permanent change (whether it has actually changed) You can ask directly. Further, the evaluation level setting means sets the evaluation level of the credibility of the attribute information based on the result of the inquiry using the inquiry means, and the attribute information that is estimated not to be changed by the estimation means , Can set a high evaluation level of authenticity.

In this way, with regard to the attribute information of each user held in the attribute information holding means that can infer whether or not it has changed by analyzing the probe information, the presence or absence of change is estimated by analyzing the probe information of each user. Is done. If the attribute information is presumed to have changed, the user of the attribute information can be directly inquired about whether or not the attribute information has changed, and the attribute information is appropriately updated based on the result. To be able to maintain accuracy, etc. In other words, the personal attribute information of each user held (registered) in the attribute information holding means is appropriately maintained and managed without taking time and effort, and can be used as accurate information.

  According to the present invention, it is possible to appropriately maintain and manage personal attribute information about a large number of users without using time and labor, and arrange it so that it can be used as accurate information.

FIG.

  Hereinafter, an embodiment of the apparatus, method, and system of the present invention will be described with reference to the drawings.

[System overall configuration]
FIG. 1 is a diagram for explaining a schematic configuration of an attribute information management system according to this embodiment. As shown in FIG. 1, the basic configuration of the attribute information management system of this embodiment is that a server device 1 and mobile communication terminals 4 (1), 4 (2),... Are connected via a network 2. It has been done. Furthermore, the information provided by the location management server 6 connected to the network 2 can be used.

  The server apparatus 1 stores and holds the attribute information of each user of the mobile communication terminals 4 (1), 4 (2),... And transmits it from the mobile communication terminals 4 (1), 4 (2),. A function as an attribute information management server that appropriately maintains and manages using probe information is realized. That is, the server apparatus 1 is realized by applying the apparatus and method of the present invention.

  The network 2 includes various wide area communication networks. The network 2 includes an IP (Internet Protocol) network, a public switched telephone network (PSTN (Public Switched Telephone Network)), a digital circuit network (ISDN (Integrated Services Digital Network)), and the like. Further, as shown in FIG. 1, the network 2 includes a mobile phone network including a large number of base stations 3 (1), 3 (2), 3IN (1),..., A wireless LAN (Local Area Network) called wifi, etc. ), And a wireless communication network conforming to a high-speed wireless communication standard called wimax or the like.

  As the mobile communication terminals 4 (1), 4 (2), etc., there are various kinds of communication functions such as mobile phone terminals, PDA (Personal Digital Assistants), information terminals called tablet terminals or pad-type terminals, etc. Things are offered. In this embodiment, each of the mobile communication terminals 4 (1), 4 (2),... Will be described as being a mobile phone terminal having a high penetration rate among various mobile communication terminals.

  Each of the mobile communication terminals 4 (1), 4 (2),... Has a GPS function, receives signals from at least three or more artificial satellites, and performs arithmetic processing to determine the current position of the own device. It can be measured. Each of the GPS functions of the mobile communication terminals 4 (1), 4 (2),... Can measure the current position of the own device with high accuracy using a technique called so-called differential GPS.

  The differential GPS performs positioning by GPS at a base station of a mobile phone terminal network whose position is known, and generates a signal indicating a deviation between the actual position of the base station and the position measured using the GPS. To send. Each mobile communication terminal 4 (1), 4 (2),... Receives a signal from this base station, and each mobile communication terminal 4 (1), 4 (2),. By correcting the current position of the own machine, the current position of the own machine can be determined more accurately.

  And each of portable communication terminal 4 (1), 4 (2), ... is provided with the function which produces | generates probe information for every predetermined timing, and transmits this to the server apparatus 1. FIG. The probe information includes at least a user ID that is identification information that can identify a user who uses the device, current time information, and current position information obtained by positioning using the GPS function. .

  As the user ID, for example, the one set at the time of purchase of the mobile communication terminals 4 (1), 4 (2),. In addition, it is possible to use a telephone number assigned to each of the mobile communication terminals 4 (1), 4 (2),... Or a unique ID of a SIM card (Subscriber Identity Module Card). That is, the user ID may be information that can uniquely specify a user who uses each of the mobile communication terminals 4 (1), 4 (2),.

  The probe information is aggregated and used as statistical information, or used for a position information providing service to an individual or group possessing a terminal or a company. In the attribute information management system of this embodiment, the probe information will be described in detail later, but the attribute information changes for the users of the mobile communication terminals 4 (1), 4 (2),. Is used to detect.

  In FIG. 1, GPS satellites 5 (1), 5 (2),... Are a part of about 30 artificial satellites that are deployed on the earth orbit and transmit a so-called GPS signal for current position measurement. Is shown. In FIG. 1, each of the base stations 3 (1), 3 (2),... Is a base station of a mobile phone network installed outdoors. In addition, in order to make it possible to use a mobile phone terminal even in an indoor place where radio waves from an outdoor base station are difficult to reach, the base station 3IN (1) also shows indoors in various facilities such as stores, for example. In some cases, a small base station connected to a mobile phone network may be installed.

  The location management server 6 is provided on the telephone company side, manages the number of each base station, the latitude and longitude of the location of each base station, and identifies the mobile phone terminal sent from the base station. It has a function of calculating and managing the position of the mobile phone terminal from the information and the information on the received electric field strength of the radio wave from the mobile phone terminal using a triangulation method. The location management server 6 also has a function of sending the calculated location information of the mobile phone terminal to the mobile phone terminal.

  Accordingly, each of the mobile communication terminals 4 (1), 4 (2),... Determines the current position of the own device by the function of the position management server 6 even when the current position cannot be measured by the GPS function. It can also be grasped. In addition, when the server device 1 receives provision of information from the position management server 6, the current position of each of the mobile communication terminals 4 (1), 4 (2),.

  In the attribute information management system of this embodiment, each of the mobile communication terminals 4 (1), 4 (2),... Generates probe information at a predetermined timing, and sends it to the server device 1. Send to. In this embodiment, as described above, the probe information is at least identification information that can identify the user of the mobile communication terminal, current time information, and current information obtained by positioning using the GPS function. Position information.

  On the other hand, the server device 1 stores and holds attribute information of each user of the mobile communication terminals 4 (1), 4 (2),. The attribute information of each user will be described in detail later, but there is a possibility that the current address, work place, family structure, hobbies, etc. may change in addition to fixed information such as user ID, name, gender and date of birth. It also contains non-fixed information. And the server apparatus 1 receives the probe information transmitted sequentially from the mobile communication terminals 4 (1), 4 (2),... And accumulates it for each user.

  At every predetermined timing, the server device 1 analyzes the accumulated probe information for a predetermined period for each user, grasps the movement route of the user, etc., and whether the non-fixed attribute information of the user has changed. Guess whether or not. For example, if the user stays at night, such as the mobile communication terminal 4 (1), the current address may have been changed, and if the place to go out in the morning changes, the work place may have changed. I can guess that

  Of course, it is premature to infer that a change has occurred in the attribute information only by the change of the first and second days. For this reason, it is possible to make a more accurate estimation by confirming that the change of the attribute information has continued for a certain period or more, or by referring to map information or POI (Point Of Interest) information described later. In addition, by considering map information and POI information, it is possible to distinguish between a home and a work place, and a travel destination and a visited place.

  In this way, in the server device 1, when it can be estimated that a change has occurred in the attribute information of the user such as the portable communication terminals 4 (1), 4 (2),. Is inquired to the user whether or not the attribute information is really changed. As a result, when the attribute information stored and held in the server device 1 is presumed to have changed, it is confirmed by inquiring the user whether or not the change has truly occurred. Then, when it is confirmed that the change that has occurred in the attribute information is a change that has truly occurred, the attribute information stored and held in the server device 1 is updated. Thereby, in the server apparatus 1, the accuracy of the attribute information of the user appropriately maintaining, managing and storing the attribute information of each user of the mobile communication terminals 4 (1), 4 (2),. Is secured.

  Note that each of the mobile communication terminals 4 (1), 4 (2),... Can receive the GPS signal from the GPS satellites 5 (1), 5 (2),. The function of the management server 6 can grasp the current position of the own device almost accurately. Further, the probe information transmitted from each of the mobile communication terminals 4 (1), 4 (2),.

  For this reason, when the base station identified by the location management server 6 by the base station ID is, for example, the indoor base station 3IN (1) shown in FIG. 1, the mobile communication terminal that has transmitted the probe information Can be identified as being located in the facility where the indoor base station 3IN (1) is installed. The inquiry about the position of the base station based on the base station ID in this case can be made from the server device 1 to the position management server 6.

  Thus, the current position of the mobile communication terminals 4 (1), 4 (2),... Cannot be measured only by the GPS function. The current positions of the mobile communication terminals 4 (1), 4 (2),... Can be obtained from the mobile communication terminals 4 (1), 4 (2),. Can be specified on the server device 1 side.

  In this embodiment, each of the mobile communication terminals 4 (1), 4 (2),... Has the same basic configuration. Therefore, unless otherwise indicated below, the portable communication terminals 4 (1), 4 (2),... Are collectively referred to as the portable communication terminal 4. In the following, the base stations 3 (1), 3 (2),... Are collectively referred to as the base station 3. In addition, the base stations 3IN (1),... Installed inside the facility are collectively referred to as indoor base stations 3IN. In the following, first, a configuration example of the mobile communication terminal 4 that generates probe information and transmits it to the server device 1 will be described, and then a configuration example of the server device 1 and details of processing performed in the server device 1 will be described. .

Then, the control unit 420 can receive a selection input of an item included in the menu from the user through the key operation unit 411, and can execute a program corresponding to the item selected by the user.

  The menu for registering various application programs that can be executed in the mobile communication terminal 4 is also provided with an item for executing transmission of probe information. Therefore, by selecting an item for executing transmission of probe information in the menu, the user of the mobile communication terminal 4 can start processing for generating and transmitting probe information at predetermined timings.

  Note that the probe information can be generated and transmitted at an appropriate timing, for example, every 30 seconds, every minute, and so on. However, it is not preferable that the timing is too long in order to accurately grasp the stopover destination. In the mobile communication terminal 4 of this embodiment, for example, probe information is generated and transmitted at a timing such as every 1 minute or every 3 minutes.

[Configuration Example of Server Device 1]
Next, a configuration example of the server device 1 according to this embodiment will be described. The server device 1 of this embodiment stores and holds the attribute information of the user of the mobile communication terminal 4 and appropriately receives the user attribute information by receiving and using the probe information from the mobile communication terminal 4 described above. It realizes a function as an attribute information management server for maintaining and managing the server. FIG. 3 is a block diagram for explaining a configuration example of the server apparatus 1 according to this embodiment.

  As illustrated in FIG. 3, the server apparatus 1 includes a connection terminal 101 to the network 2, a communication I / F 102, and a probe information file 103. The server device 1 includes a map database (hereinafter abbreviated as map DB) 104, a POI database (hereinafter abbreviated as POIDB) 105, and a user database (hereinafter abbreviated as user DB) 106. Is provided. Further, the server apparatus 1 includes an attribute information change estimation unit 107, a change information holding unit 108, an attribute information confirmation update unit 109, an attribute information providing unit 110, a control unit 120, a hard disk drive (hereinafter abbreviated as HDD). 130).

  The control unit 120 controls each unit of the server device 1, and is a computer device configured by connecting a CPU 121, a ROM 122, a RAM 123, and an EEPROM 124 through a CPU bus 125 as shown in FIG. 3. The CPU 121 reads and executes so-called firmware such as BIOS (Basic Input / Output System) stored in the ROM 122 or the EEPROM 124 and application software stored in the HDD 130 described later. Then, the CPU 121 generates a control signal to each unit and supplies it to each related unit, or receives data from each unit and processes it.

  The ROM 122 stores various firmware executed by the CPU 121 and data necessary for processing in advance. The RAM 123 is used mainly as a work area in various processes, such as temporarily storing intermediate results of the processes. The EEPROM 124 is a rewritable so-called nonvolatile memory, and stores and holds data that should be held even when the power is turned off. Specifically, the EEPROM 124 stores and holds various information such as firmware such as BIOS and various setting parameters.

  The HDD 130 includes a hard disk as a recording medium, and performs writing / reading on the hard disk in accordance with the control of the control unit 120. The hard disk of the HDD 130 stores, for example, various application programs, data obtained by various processes, and the like.

  The connection terminal 101 forms a connection end with the network 2. A communication line from the network 2 is connected to the connection terminal 101. The communication I / F 102 receives various information addressed to the own device transmitted through the network 2, converts this into information in a format that can be processed by the own device, and supplies the information to the control unit 120. Further, the communication I / F 102 converts various information for transmission supplied through the control unit 120 into a signal of a format to be transmitted to the network 2 and transmits the signal to the network 2.

  The probe information file 103 accumulates probe information received from the mobile communication terminals 4 of many users received through the connection terminal 101 and the communication I / F 102. FIG. 4 is a diagram for explaining an example of stored data (probe information) stored in the probe information file 103.

  As shown in FIG. 4, the probe information file 103 of this embodiment is configured to accumulate probe information including date and time information, positioning position information, and provided position information for each user ID (for each user). The user ID is the same as that included in the transmitted probe information, and is information that can uniquely identify the user who uses the mobile communication terminal 4 as described above. Each of the date / time information, the positioning position information, and the provided position information is information included in the probe information. Of these, the positioning position information is the current position information measured by the GPS function of the mobile communication terminal 4. The provided position information is current position information provided by the mobile communication terminal 4 from the position management server 6 described above.

  The example of the accumulated data in the probe information file shown in FIG. 4 is an example for a user whose user ID is “00001”. In this example, the position (latitude, longitude) at which the user with the user ID “00001” was at 14:10:20 on June 10, 2011 is (X11, Y11) in the positioning position information. The provided position information indicates (X21, Y21).

  Further, the position (latitude and longitude) at which the user with the user ID “00001” was at 14:11:20 on June 10, 2011 is not grasped by the positioning position information, but is provided by the provided position information (X22, Y22). Similarly, the position (latitude, longitude) at which the user with the user ID “00001” was at 15:20:20 on June 10, 2011 is not grasped by the positioning position information, but the provided position information (X22 Y22).

  Therefore, it can be seen that the user whose user ID is “00001” was at the position measured by the GPS function at the time of 14:10:20 on June 10, 2011. At least after 14:11:20 on June 10, 2011, the current position cannot be measured by the GPS function, but the position can be specified by the function of the position management server 6 Can be recognized. In this way, the location of the user of the mobile communication terminal 4 can be accurately grasped by the probe information.

  Note that the position indicated by the positioning position information and the position indicated by the provided position information are usually substantially the same position, but are not completely the same, and may include a slight error. As described above, the probe information file 103 stores the probe information transmitted from the mobile communication terminal 4 for each user of the mobile communication terminal 4 in chronological order according to the current time information included in the probe information. .

  In this embodiment, the map DB 104 stores and holds detailed map information in Japan. The map information includes the location of various landmarks such as mountains, rivers, towns, roads, railway lines, various stores, hospitals, clinics, schools, police stations, fire stations, shrines and temples, administrative boundaries, etc. The size and the like can be accurately expressed. The map DB 104 stores and holds map data (map drawing data) such as vector data and raster data for drawing a map of Japan nationwide in association with latitude / longitude information. The map DB 104 also stores and holds note data displayed on the map in association with latitude / longitude information.

  The POIDB 105 stores and holds various information about various facilities such as universities, high schools, junior high schools, elementary schools, stores, and companies, and so-called bases such as various places such as mountains, rivers, and roads. Specifically, information such as latitude / longitude, name, address, genre, and mesh code of the specific place (POI) is accumulated. Therefore, it is possible to grasp in detail from the POI information of POIDB 105 what kind of place is specified by the target latitude and longitude, what kind of facility, and the like.

  The user DB 106 stores and holds various attribute information (user information) about the user of the mobile communication terminal 4 that transmits probe information to the server device 1. FIG. 5 is a diagram for explaining an example of attribute information stored and held in the user DB 106. As shown in FIG. 5, in this embodiment, the user DB 106 includes a user ID, a disclosure range of attribute information, a name, a gender, a date of birth, a telephone number, an e-mail address, a current address, a residence form, a family structure, Data consisting of occupation, work location, income, hobbies, stopovers, etc. is registered.

  The user ID is the same as the user ID used in the probe information file 103 in FIG. Information other than the user ID is basically registered by the user when the mobile communication terminal 4 is purchased. Here, the disclosure range of the attribute information is information indicating how far the attribute information can be disclosed to other persons, such as “cannot disclose all”, “can disclose all”, “name, phone number, current address The scope of disclosure is indicated as “not disclosed”. Of course, information that does not permit disclosure and information that permits disclosure can be individually specified and registered.

  Depending on the disclosure range of the attribute information, points are given to the user every month, for example, and can be used for payment of communication charges of the mobile communication terminal 4 or exchange of prizes. In this way, the provision of points according to the disclosure range of attribute information is an incentive for the user to disclose his / her own attribute information as far as possible.

  The name, gender, date of birth, telephone number, and e-mail address registered in the user DB 106 are basically fixed information that does not change. However, the telephone number and the e-mail address can be changed according to the user's request, and in that case, it can be changed according to a request from the user.

  The current address, residence form, family structure, occupation, etc., work location, etc., income, hobbies, stopovers, and other information registered in the user DB 106 can also be initially registered by the user. However, these pieces of attribute information are non-fixed information that may change. For this reason, the non-fixed information in the user DB 106 is a target for estimating whether or not a change has occurred by collecting and analyzing probe information transmitted from the mobile communication terminal 4 for a predetermined period in the server device 1. .

  It is not necessary for the user to first register all of the current address, residence form, family structure, occupation, etc., work location, etc., income, hobbies, stopovers, and other information. As will be described later, the attribute information that is not registered can be estimated by analyzing the probe information stored in the probe information file 103 for each user, and updated after obtaining user confirmation. In addition, among the user attribute information registered in the user DB 106, the current address and work location can have not only the address information but also the latitude and longitude of the address location. The latitude / longitude can be obtained by referring to the map DB 104 based on the address information.

  Then, the attribute information change estimation unit 107 and the attribute information confirmation update unit 109 of the server device 1 cooperate to realize a function of appropriately maintaining and managing user attribute information registered in the user DB 106. The functions of the attribute information change estimation unit 107 and the attribute information confirmation update unit 109 will be specifically described.

  The attribute information change estimation unit 107 estimates whether or not a change has occurred in the user attribute information registered in the user DB 106 by analyzing the probe information for a predetermined period accumulated in the probe information file 103 for each user. Perform the process. In this case, the attribute information change estimation unit 107 first analyzes the probe information for a predetermined period accumulated in the probe information file 103 for each user, and grasps the movement route (action trajectory) of each user for each day. .

  FIG. 6 is a diagram for explaining grasping of a user's movement route performed by the attribute information change estimation unit 107. FIG. 6 specifically shows the travel route grasped from 18:20 on June 9, 2011 to 18:10 on June 10, 2011 for the user whose user ID is “00001”. .

  In FIG. 6, the date corresponds to the date (year / month / day) of the date / time information of the probe information shown in FIG. 4, and the time corresponds to the time information of the date / time information of the probe information. Further, in FIG. 6, positions such as (X1, Y1), (X2, Y2) indicated by (latitude, longitude) correspond to the positioning position information or the provided position information of the probe information. For example, when the positioning position information exists in the probe information, this is used, and when the positioning position information does not exist, the provided position information is used. Thereby, the reliability of probe information is maintained.

  That is, the attribute information change estimation unit 107 first sorts probe information for a predetermined period for each user and sorts them in chronological order, sorts out overlapping probe information, and specifies a movement start position and a movement end position. In this way, as shown in FIG. 6, the user's stopover destination, the staying time at the stopover point, the moving section, and the moving means are specified.

  In the case of the example shown in FIG. 6, the user whose user ID is “00001” stays at the position (X1, Y1) from 18:20 on June 9 to 7:30 on the next 10th. Yes. In general, the stopover (stay place) from night to next morning is often at home. Then, the current position of the probe information changes from 7:31 to 7:44 on June 10, 2011, reaches the position (X2, Y2) at 7:45, and reaches the position (X2, I am staying at Y2).

  In this case, the current position at approximately 7:31 is the change start position, and the current position at 7:44 is the change end position. A section from the change start position to the change end position is a movement section. The position (X2, Y2) where the user stayed from 7:45 to 7:50 is the first stop.

  The movement distance from the change start position to the change end position of the current position can be grasped by plotting each of the current positions (latitude and longitude) of the probe information of the corresponding part on the map information of the map DB 104. Then, the moving speed of the moving section can be determined by dividing the grasped moving distance by the time taken to move. The moving means can be discriminated according to the calculated moving speed.

  That is, for example, if the calculated moving speed is less than 5 km / h, the moving means is walking, and if the calculated moving speed is 5 km / h or more and less than 30 km / h, the moving means can be determined to be a bicycle. Further, when the moving speed is 30 km / h or more, the grasped moving route does not pass on the railway track, and the grasped moving state does not stop at the bus stop, it is determined that the moving means is an automobile. can do.

  Further, when the moving speed is 30 km / h or more and the grasped moving route passes on the railroad track, it can be determined that the moving means is a train. Further, when the moving speed is 30 km / h or more and the grasped moving state is a mode (pattern) that stops at the bus stop, it can be determined that the moving means is a bus.

  Whether the movement route is on a road or a railway track can be grasped by referring to the map information in the map DB 104 based on the current position of the probe information. In addition, when the travel route is on a road, whether the travel means is a car or a bus is determined by checking the change point of the travel speed based on the map information of the map DB 104 or the POI information of the POIDB 105, and the change point is It can be distinguished according to whether or not.

  In the case of the example shown in FIG. 6, it is understood that the movement from the position (X1, Y1) to the position (X2, Y2) is by walking. Further, the location specified by the position (X2, Y2) can be specified by referring to the map information in the map DB 104 or the POI information in the POIDB 105. In the case of the example illustrated in FIG. 6, the place indicated by the position (X2, Y2) is specified to be a nursery school.

  Similarly, by analyzing the probe information using the map DB 104 and the POIDB 105 as well, as shown in FIG. 6, the movement route of the user whose user ID is “00001” is known. That is, in the example shown in FIG. 6, the user whose user ID is “00001” moves on foot from 7:51 to 7:59, and is at the position (X3, Y3) at 8:00. ○ Arrive at the station and stay at the station until 8:05. Then, move by train from 8:06 to 8:19, arrive at △△ station (X4, Y4) at 8:20, and walk from 8:21 to 8:30 At 8:30, we arrived at □□ Co., Ltd., which is the position (X5, Y5).

  I stayed at □□ Co., Ltd. until 17:05 and moved on foot from 17:06 to 17:15. At 17:16, I arrived at the △△ station (X4, Y4). I stayed at △△ station until 17:19. Then, we moved by train from 17:20 to 17:34, arrived at the station (X3, Y3) at 17:35, and started moving on foot at 17:36. At 17:47, we arrived at the nursery school at the position (X2, Y2). Thereafter, the user starts to move on foot at 17:51, and arrives at a place (home) which is a position (X1, Y1) at 18:10.

  The attribute information change estimation unit 107 performs such analysis for each user and each day by using probe information for a predetermined period such as 10 days, 20 days, or 1 month. And (1) Stop by, (2) Type of stop (distinguishment between housing, nursery school, company, etc.), (3) Considering the staying time at the stop, etc. Etc. can be guessed.

  If the movement along the movement route as shown in FIG. 6 continues for about one month, for example, it can be estimated that the location indicated by the position (X1, Y1) is the home (the current address). When there is POI information corresponding to the current address, it can be determined whether the place is an apartment, an apartment, or a detached house. Further, it can be estimated that the work place is a □□ corporation indicated by the position (X5, Y5).

  In addition, based on the POI information of the place of work, it is possible to infer occupations such as company employees, civil servants, and teachers. In addition, information on income such as approximate monthly income is obtained by considering information such as work place, work place, working time, user age and gender, as well as information on salaries, etc. published on the Web. Can also guess. In addition, it can be assumed that there are children who go to the nursery school because they stop by the nursery school in the morning and evening. It can also be estimated that walking and a train are used for movement, and that the movement section on the train is from XX station to △△ station.

  Note that the example described with reference to FIG. 6 is an example, and the attribute information change estimation unit 107 can make various assumptions about the user attribute information by grasping the user's movement route as described above. It becomes possible. For example, if an elementary school is a regular stopover, it can be inferred that there are elementary school children.

  In addition, when a player comes to a stadium where a soccer game is held (soccer field), it can be presumed that watching soccer is a hobby. It can be understood that the place where the user stopped is a stadium by referring to the map DB 104 and the POIDB 105 as described above. Further, whether or not a soccer game has been held while the user is staying at the place can be determined by referring to information on a Web page related to a soccer game disclosed on the Internet. Then, according to the frequency of stopping at a stadium where a soccer game is being held, it is also possible to estimate the eagerness related to watching a soccer game.

  Similarly, when people often come to places where fishing can be done, such as rivers and seas, fishing becomes a hobby, and the degree of eagerness can also be estimated based on the frequency of visits and the length of stay. Moreover, when it comes to stop by a golf course, a golf driving range, and a golf shop well, golf becomes a hobby and the enthusiasm can also be estimated based on the frequency and the staying time.

  In addition, when a user comes to the wedding hall, it can be estimated that the user is getting married, and the place where the user's home (current address) is presumed is the home of another user ( When it comes to coincide with a place that is presumed to be the current address, it can be assumed that the user has married (has lived with) the other user. In this case, it can be estimated that a change has occurred in the family structure of the user and the other user. Furthermore, when the user comes to an obstetrics and gynecology hospital, it can be estimated that childbirth is near. After this, the user stays at the obstetrics and gynecology hospital for a certain period of time (hospitalized), and when a baby-related facility such as a baby goods store stops, a child is born, that is, the family structure changes Can be guessed.

  In recent years, the penetration rate of mobile phone terminals is high, and the number of children who have their own mobile phone terminals is increasing in the upper grades of elementary school. In junior high school and high school, more children have their own mobile phone terminals. Therefore, not only the probe information is analyzed for each user, but also a merge process of common points with the analysis results for each user is performed, so that it is possible to accurately estimate changes in the family structure.

  Then, the attribute information change estimation unit 107 analyzes the probe information for a predetermined period for each user, so that the home (current address), dwelling form, family structure, occupation, etc., office, income, hobby, stopover, etc. Suppose that various kinds of information can be estimated. In this case, the attribute information change estimation unit 107 compares the estimation result with the corresponding attribute information in the user DB 106 for each user, and estimates whether or not a change has occurred.

  It is assumed that the attribute information change estimation unit 107 can estimate that the user attribute information has changed. In this case, the attribute information change estimation unit 107 records the estimated content of the change in the change information holding unit 108, and the attribute information confirmation update unit 109 stores the user estimated to have changed the attribute information and the content of the estimation. Notice.

  FIG. 7 is a diagram for explaining an example of data held in the change information holding unit 108. As shown in FIG. 7, the change information holding unit 108 includes a user ID of a user who can estimate that the attribute information in the user DB 106 has changed, an item of attribute information (change estimation item) that is estimated to have changed, and a change. The later contents and the date on which the estimation was made (estimated date) are recorded. In the case of the example shown in FIG. 7, each information is shown to be an estimation result on July 1, 2011.

  In the case of the example shown in FIG. 7, since the user whose user ID is “00001” has detected that the stopover where he / she stays from night to next morning has changed, the “current address” (Saitama Prefecture Saitama) Information indicating that it is assumed that the city has changed to (City ...) is held. In addition, it is estimated that the “work location” has changed to (Shinjuku-ku, Tokyo ...) because the user whose user ID is “00008” has detected that a change has occurred in his / her home in the morning. Information indicating that this has been done is retained. In addition, as described above, the user whose user ID is “00112” increases the number of children due to childbirth based on staying at a gynecological hospital for a certain period of time, the fact that the baby goods store is a stopover, etc. Information indicating that it is assumed that the “family composition” has changed is held.

  In addition, it is assumed that the user whose user ID is “00020” has assumed that golf has been added to “hobbies” because a golf course, a driving range, a golf shop, and the like have come to stop by. The information shown is held. In addition, “family composition” has changed because other users staying in the same place as the home (current address) of the user whose user ID is “00035” from night to next morning have changed (the number of family members living together has increased) ) Holds information indicating that it has been estimated that.

  As shown in FIG. 7, the same information as the estimation result held in the change information holding unit 108 is also notified to the attribute information confirmation updating unit 109. Therefore, the attribute information confirmation update unit 109 transmits an e-mail that prompts the user who is assumed to have changed the attribute information to access a predetermined Web page for checking the change. .

  Then, it is assumed that the user accesses the Web page instructed by the e-mail, performs a confirmation input, and the confirmation input confirms that the estimation result that the attribute information has changed is correct. In this case, the attribute information confirmation update unit 109 executes an update process for changing the changed attribute information to the changed attribute information in the registration information of the user held in the user DB 106. In this way, the attribute information in the user DB 106 is appropriately maintained and managed. As a result, the attribute information of each user registered in the user DB 106 is used as highly reliable information at the time of providing the information described above, and the attribute information whose disclosure is permitted by the user is provided to companies and the like. Can be.

  Then, the attribute information providing unit 110 is the attribute information of the user who has approved the disclosure of the attribute information in response to the request from the contracted company or the like, and the attribute information of the user that matches the requested condition Process to provide. As described above, since the user attribute information is always maintained and managed in an accurate state, companies and the like can easily obtain highly reliable user attribute information.

[Summary of Processing of Attribute Information Change Estimation Unit 107]
Next, the processing performed in the attribute information change estimation unit 107 of the server device 1 of this embodiment will be summarized with reference to the flowchart of FIG. FIG. 8 is a flowchart for explaining processing performed by the attribute information change estimation unit 107.

  The attribute information change estimation unit 107 executes the process shown in FIG. 8 at a predetermined timing such as every month. Then, the attribute information change estimation unit 107 first extracts probe information for a predetermined period (for example, the latest past one month) for each user (step S101). Then, the attribute information change estimation unit 107 specifies the user ID of the user to be analyzed based on the extracted probe information (step S102).

  Then, based on the probe information for a predetermined period of the user who specified the user ID, the movement path (behavior pattern) of the user in the predetermined period is specified as described with reference to FIG. 6 (step S103). In the process of step S103, the map DB 104 and the POIDB 105 are referred to as necessary. Thereafter, the attribute information change estimation unit 107 grasps the user's stop location, stop time, stay time at the stop location, stop period at each stop location, and the like based on the identification result of step S103. Based on the current address, occupation, etc., location, income, hobbies, presence / absence of children, etc. (step S104).

  As described above, when the current address changes due to moving, or when the occupation, work location, etc. change due to employment, change of job, advancement, etc., these are analyzed by analyzing the user's action trajectory according to the probe information. The state after the change can be detected. Also, based on the specified stop-off location, the work place and part-time job are specified, the age of the user and the work time (stay time), wage information of the work place and part-time work disclosed on the Internet, general It is also possible to roughly estimate the user's income based on information such as wage market prices.

  You can also specify your hobbies based on the specified stop-off location or holiday destination, or if you stop by the specified stop-off day at a nursery school or kindergarten almost every day, Various analyzes such as knowing that there are children are possible. In this way, it is possible to distinguish various attribute information based on information such as what place to stop by, how often to stop, and whether there is a companion. Such a determination can be made as a pattern in the process in step S104, and can be determined based on the pattern.

  Further, the attribute information change estimation unit 107 confirms the presence or absence of another user who stops at the place specified as the current address in step S104 and grasps the family living together (step S105). If there is another user who stops by for a long time, it can be determined that the other user is the family of the user with the user ID specified in step S102.

  Then, the attribute information change estimation unit 107 refers to the attribute information (registration information) in the user DB 106 based on the user ID specified in step S102, and based on the estimation results in steps S104 and S105, It is confirmed whether or not the attribute information has changed (step S106). That is, in step S106, when the information grasped in steps S104 and S105 is different from the attribute information of the user DB 106, it is estimated that there is a change in the attribute information of the user.

  Then, the attribute information change estimation unit 107 determines whether or not the confirmation result in step S106 indicates that the attribute information has changed (step S107). If it is determined in the determination process in step S107 that the change is indicative of a change, the attribute information change estimation unit 107 instructs the attribute information confirmation update unit 109 to change the user ID of the user whose attribute information is estimated to be changed. The attribute information after the change and the estimated processing date are notified, and the notification content is stored in the change information holding unit 108 (step S108).

  In the determination process of step S107, when it is determined that there is no change in the attribute information, and after the process of step S108, the attribute information change estimation unit 107 determines whether or not all the extracted probe information has been processed for each user. A determination is made (step S109). In the determination process of step S109, when it is determined that not all of the extracted probe information has been processed for each user, the process from step S102 is repeated, and the probe information analysis process for the next user is performed. If it is determined in step S109 that all the extracted probe information has been processed for each user, the process shown in FIG. 8 is terminated.

  As described above, when the attribute information change estimation unit 107 estimates that the attribute information registered in the user DB 106 has changed by analyzing the probe information, the attribute information change estimation unit 107 notifies the attribute information check update unit 109 of the change. In addition to the notification, the estimation result can be stored in the change information holding unit 108 in the manner shown in FIG.

[Summary of Processing of Attribute Information Confirmation Update Unit 109]
Next, processing performed in the attribute information confirmation update unit 109 of the server device 1 of this embodiment will be summarized with reference to the flowcharts of FIGS. FIG. 9 and FIG. 10 are flowcharts for explaining processing performed by the attribute information confirmation update unit 109.

  The attribute information confirmation update unit 109 always executes the process shown in FIG. 9 and receives a notification (change notification) indicating that the attribute information from the attribute information change estimation unit 107 is estimated to have changed. It is determined whether or not a change notification has been accepted (step S201). When it is determined that the change notification has not been received, the processing from step S201 is repeated, and the change notification is awaited.

  If it is determined in the determination process in step S201 that a change notification has been received, the attribute information confirmation update unit 109 prompts the user who is assumed to have changed the attribute information to access a predetermined Web page. Is created (step S202). FIG. 11 is a diagram for explaining an example of the e-mail. As shown in FIG. 11, the e-mail in this example includes a text requesting access to a predetermined Web page for confirming change of attribute information, a URL (Uniform Resource Locator) indicating an access destination, and a confirmation. And a sentence for notifying that points will be awarded when cooperating with. Here, the Web page specified by the URL included in the e-mail is provided by the server device 1 by the function of the attribute information confirmation update unit 109.

  Then, the attribute information confirmation update unit 109 transmits the e-mail created in step S202 with the e-mail address of the user who is assumed to have changed the attribute information registered in the user DB 106 as a destination (step S203). . The e-mail is sent to the network 2 through the control unit 120, the communication I / F 102, and the connection terminal 101, and is sent to the user's mailbox provided on the network 2. Thereafter, the attribute information confirmation update unit 109 repeats the processing from step S201.

  In this way, the e-mail transmitted from the server device 1 is received by the user's mobile communication terminal 4, displayed on the display screen 413G of the display unit 413 of the mobile communication terminal 4, and provided to the user. When the user performs an operation of selecting the URL displayed in the e-mail, the user can access the Web page specified by the ULR.

  Then, the attribute information confirmation update unit 109 always executes the process shown in FIG. 10 and determines whether or not the access request to the predetermined web page requested from the user through the above-described e-mail has been received (step S301). ). An access request to a predetermined Web page is received by the control unit 120 through the connection terminal 101 and the communication I / F 102, and the fact that the access request has been received is notified to the attribute information confirmation update unit 109 through the control unit 120. If the attribute information confirmation update unit 109 determines that it has not received an access request to the predetermined Web page, it repeats the processing from Step S301 and waits for an access request from the user to the predetermined Web page. .

  When it is determined in step S301 that the access to the predetermined web page has been received from the user, the attribute information confirmation update unit 109 provides the predetermined web page to the access source user, and the attribute information Confirmation input is requested (step S302). In this case, it is possible to transmit a request for access to a predetermined Web page from a user including, for example, a user ID that identifies the user.

  Thereby, the attribute information confirmation update unit 109 refers to the information in the change information holding unit 108 based on the user ID of the user, and grasps which attribute information change of the user is estimated. Then, the attribute information confirmation update unit 109 configures a Web page corresponding to the user and provides the Web page to the user. FIG. 12 is a diagram for explaining an example of a predetermined Web page provided to the user. The example shown in FIG. 12 is an example of a Web page provided to a user who is assumed to change the current address.

  As shown in FIG. 12, the Web page has a text indicating that it is a Web page for confirming the change of attribute information, a text indicating that there is attribute information whose change is estimated, and the change. And a check field for confirming whether or not there is a change in the attribute information. Furthermore, an area where the reason for changing attribute information can be described is also provided. Therefore, the texts indicating that there is attribute information that is expected to change are: "Did your work location change recently?", "Did your child have recently been born?", "Recently you started playing golf. It can be changed as appropriate.

  Such a Web page is provided to the mobile communication terminal 4 of the access source user, displayed on the display screen 413G of the display unit 413, and provided to the user. Then, the user inputs a check in the displayed check field, describes the reason if necessary, and performs a transmission operation such as selecting a “transmission” icon, whereby the estimated change of the attribute information is changed. Information indicating whether it is correct or incorrect can be transmitted to the server apparatus 1. When an incorrect input is made, the correction input can be performed by performing a correction operation such as selecting the “BS” icon before transmission.

  Then, the attribute information confirmation update unit 109 receives a confirmation input from the user through the Web page, and whether the confirmation input affirms a change in the attribute information, in other words, the attribute information needs to be updated. (Update OK) or not (step S303). When it is determined in the determination process in step S303 that the attribute information needs to be updated, the attribute information confirmation update unit 109 changes the attribute information that is estimated to have changed for the user registered in the user DB 106. Update to later attribute information (step S304). The changed attribute information is held in the change information holding unit 108 as described above.

  In the determination process in step S303, the process from step S301 is repeated after determining that the attribute information does not need to be updated (the attribute information has not changed) and after the process in step S304.

  As described above, the attribute information confirmation update unit 109 determines whether or not the estimation of the change is correct for the user who is estimated that the attribute information has changed by using the e-mail and the predetermined Web page. (Whether or not the change really occurs). Then, when it can be confirmed that the estimation of the change is correct, the attribute information of the corresponding user in the user DB 106 can be updated to the estimated information after the change.

[Effect of the embodiment]
As described above, the server device 1 stores and holds the attribute information of the user of the mobile communication terminal 4, but even if a change occurs in the attribute information of the user, the attribute information is changed for the user. There is no need to make a declaration. The server device 1 can estimate the attribute information of each user by collecting and analyzing the probe information from each mobile communication terminal 4.

  Then, when it can be inferred that the attribute information stored and held by the server device 1 has changed, the user is actually confirmed whether or not the guess is correct, and it can be confirmed that it is correct. In addition, the attribute information stored and held by the server device 1 can be updated to new information. Therefore, the user of the mobile communication terminal 4 can also appropriately maintain and manage the user attribute information stored and held in the server device 1 without bothering the operator on the server device 1 side. it can.

  When the user permits the disclosure of attribute information, accurate and reliable user attribute information can be provided to a third party who needs attribute information such as a company. Accordingly, a company or the like can obtain target high-quality user attribute information without spending time or cost in order to obtain user attribute information.

  In addition, for users who have permitted the disclosure of user attribute information, the user can be given points that can be used for payment of communication charges or exchange for cash or prizes, depending on the scope of permission of the attribute information. Can give merit to publishing their own attribute information.

[Modification]
In the above-described embodiment, the server apparatus 1 is described as including the map DB 104 and the POIDB 105, but the present invention is not limited to this. The map DB 104 and the POIDB 105 can be configured so that the server device 1 uses what is prepared in another server device on the network 2.

  Further, it is possible to set an evaluation level (evaluation value) of the credibility for each of the user attribute information stored and held in the server device 1. For example, when there is no difference between the attribute information stored and held and the attribute information estimated by analyzing the probe information, the credibility level of the attribute information is set high. Further, as described above, it is estimated that a change has occurred in the attribute information stored and retained, and this is confirmed by the user, and there is a response from the user to the confirmation, and the accuracy of the attribute information is confirmed. If it can be maintained, the credibility level of the attribute information is set high. Conversely, if there is no response from the user to the confirmation, the credibility level of the attribute information is set low. In this way, for each piece of attribute information, it is possible to properly distinguish between accurate and inaccurate ones and provide area marketing information using high-quality attribute information to companies and the like. .

  In the above-described embodiment, when the change of the attribute information is confirmed, the attribute information is changed and the presence / absence of the change is inquired. However, the present invention is not limited to this. For example, when the current address or work place changes, a new current address or work place obtained by guessing may be indicated and confirmation of whether it is correct may be requested. That is, the content of the estimated attribute information after the change can be shown to the user, and the user can be confirmed whether it is correct or not.

  In the above-described embodiment, the change of the attribute information is confirmed by transmitting an e-mail requesting access to a predetermined Web page for confirmation. However, the present invention is not limited to this. is not. For example, an e-mail requesting confirmation of change in attribute information may be transmitted to the user, and a reply to the e-mail may be requested from the user. The server device 1 confirms the content of the returned e-mail, and if the reply e-mail having the content that the change in attribute information is correct is confirmed, the attribute information of the user who sent the reply e-mail is updated. That's fine.

  In addition, when it is estimated that the attribute information has changed, a list including the user ID of the user whose change is estimated, the content of the change, the user's telephone number, and the like is created. Then, based on the list, the operator on the server device 1 side makes a call directly to the user and confirms it. When confirmation of change is obtained by the telephone, the server apparatus 1 may be configured to update the attribute information of the user in the user DB 106 in response to an instruction input from the operator. As described above, in the case of the above-described embodiment, the confirmation with the operator interposed is confirmed directly when there is no access to a predetermined Web page for confirmation from the user or when the content of the change is complicated. It may be used when it is preferable.

  In addition, the estimation of the change in the user attribute information in the above-described embodiment is an example, and by using the probe information from the mobile communication terminal 4, various attribute information of the user can be estimated. For example, it can be estimated at which stage the user or his / her family is in the life cycle (infant, infant, child, boy, adolescent, middle-aged, middle-aged, elderly, etc.). In addition, it can be inferred at which stage the user or his / her family is in the life stage (childcare, schooling, employment, single, love, marriage, childcare, education, child separation, retirement, later years, etc.).

  In addition, it is possible to infer lifestyles (hobby preferences, behavioral ranges, family forms, dependents, participating organizations, circles, community activities, etc.). It is also possible to infer life bases such as gender, age, educational background, qualifications, occupation, income, disposable income, assets, and housing style. For these various attributes of users belonging to the life cycle, life stage, lifestyle, and life base, probe information from the mobile communication terminal 4 carried by the user is collected, and the action pattern based on the user's action trajectory The existence of other users who act with the user can be estimated in a comprehensive manner.

  More specifically, for each of the above-described attribute information for the user, a large number of reference information regarding what kind of behavior the user takes can be assumed to correspond to the attribute information is prepared. . Then, the attribute information change estimation unit 107 of the server device 1 analyzes the probe information, so that when and where the user having the mobile communication terminal has gone, Information such as whether a special event was held. Then, the attribute information change estimation unit 107 estimates (determines) whether the acquired information and the above-described reference information match, or whether the attribute information corresponds to the attribute information according to the degree of match. Determine.

  Therefore, the disposable income can be estimated from the estimated income by maintaining the above-described reference information. Also, using POI information and attribute information of other users who are with you, we can infer information about assets such as whether the current address is home or rent, where the bank is, and whether there is a transaction with a securities company You can also. In addition, if the user's gender is unknown, the gender can be inferred from the location of the stop, etc., and the educational background and qualifications held, etc., depending on the status of participation in alumni associations, seminars, workshops, etc. Can also be understood.

  For this reason, not only the map DB 104 and POIDB 105 provided in the server apparatus 1 but also information such as an event DB and various Web pages existing on the network 2 is referred to, and what is being done at the user's stop. Also consider the information. In this manner, by using the probe information, it is possible to make a detailed guess about various attribute information of the user.
