<Overall configuration of information analysis system 1>
An information analysis system 1 according to a preferred embodiment of the present invention will be described. FIG. 1 shows the overall configuration of the information analysis system 1.

As shown in FIG. 1, the information analysis system 1 includes an in-vehicle navigation device 10, a mobile terminal 20, and an information analysis device 30. These devices and terminals are connected to each other via a communication network 50 so that they can communicate with each other. In the figure, information transmitted and received by each device and each terminal is also illustrated, but these information are merely examples. In the present embodiment, information other than that illustrated may be transmitted and received.

The in-vehicle navigation device 10 is a device that performs navigation (route guidance) for a user who has boarded the vehicle 60a. The in-vehicle navigation device 10 performs route guidance from the current position to the destination based on a user request. The in-vehicle navigation device 10 also has a function of positioning position information of the in-vehicle navigation device 10 (that is, position information of the vehicle 60a). The position information measured by the in-vehicle navigation device 10 is appropriately transmitted to the information analysis device 30.
The vehicle-mounted navigation device 10 can be realized by a car navigation device that can be installed and transported on a vehicle 60a that is a moving body, or a PND (Portable Navigation Device) that is simply installed on the vehicle 60a that is a moving body.

The mobile terminal 20 is a mobile terminal used by a user who gets on the vehicle 60b. The portable terminal 20 has a function of positioning the position information of the portable terminal 20 (that is, the position information of the vehicle 60b), like the vehicle-mounted navigation device 10 described above. The position information measured by the mobile terminal 20 is appropriately transmitted to the information analysis apparatus 30 in the same manner as the position information measured by the in-vehicle navigation device 10.
The mobile terminal 20 can be realized by a smartphone, a mobile phone, a tablet terminal, a notebook computer, or other portable electronic devices.

In the figure, a set of the in-vehicle navigation device 10 and the vehicle 60a and a set of the mobile terminal 20 and the vehicle 60b are illustrated, but the number of these sets is not particularly limited. Moreover, in the following description, when calling the vehicle 60a in which the vehicle-mounted navigation device 10 is mounted or the vehicle 60b on which the user using the mobile terminal 20 gets on without distinction, the alphabet at the end is simply omitted, This is called “vehicle 60”.

The information analysis apparatus 30 creates a visiting facility list for each moving body by category based on moving body visiting data visited by the moving body within a predetermined period, which is processing unique to the present embodiment. This is a device that makes it possible to easily grasp user preferences of moving objects belonging to the same cluster as a more categorized cluster by clustering the moving objects based on the list.
For this reason, the information analysis device 30 acquires the position information of each vehicle 60 from the in-vehicle navigation device 10 and the portable terminal 20, thereby creating a position information database that is a database for the position information of each vehicle 60. Then, the information analysis apparatus 30 analyzes the created location information database to create a category-specific visited facility list in which, for each vehicle 60, facilities visited by category are arranged in descending order of the number of visits, for example. .

Then, the information analysis device 30 performs clustering processing on the mobile users based on the category visit facility list created for each mobile user, thereby indicating which cluster the mobile users are classified into. Assign attributes (profiles). By doing so, the information analysis apparatus 30 distributes the distribution information regarding the facility to the mobile users belonging to the same cluster and having the attribute associated with the facility. The detailed contents of these analysis information and analysis conditions will be described later. The information analysis device 30 can be realized by a server system including, for example, one or more computers.

The communication network 50 is realized by a network such as the Internet or a mobile phone network, or a network combining these. Further, a LAN (Local Area Network) may be included in a part of the network.

The vehicle 60 is a moving body on which a user of the in-vehicle navigation device 10 or the mobile terminal 20 gets on. The vehicle 60 is realized by, for example, a four-wheeled vehicle, a motorcycle, a bicycle, or the like.

<Functional blocks included in the in-vehicle navigation device 10>
Next, functional blocks provided in the in-vehicle navigation device 10 will be described with reference to the block diagram of FIG.
Here, the in-vehicle navigation device 10 is supplied with power from the vehicle 60a, and automatically starts when the ignition switch of the vehicle 60a is turned on (starts the engine) by the user who gets on the vehicle 60a. And the vehicle-mounted navigation apparatus 10 is operated until the ignition switch of the vehicle 60a is turned off (the engine is stopped) by the user who gets on the vehicle 60a.

As shown in FIG. 2, the in-vehicle navigation device 10 includes a control unit 11, a storage unit 12, a communication unit 13, a sensor unit 14, a display unit 15, and an input unit 16.

The control unit 11 includes an arithmetic processing device such as a microprocessor, and controls each unit constituting the in-vehicle navigation device 10. Details of the control unit 11 will be described later.

The storage unit 12 is configured by a semiconductor memory or the like, and is used for performing a control program called firmware or an operating system, a program for performing route guidance processing, and transmission processing of position information to the information analysis device 30. Each program such as a program and various other information such as map information are stored. In the figure, as information stored in the storage unit 12, position information 121 and identification information 122, which are information related to the transmission process of position information, are illustrated.

The position information 121 is position information of the in-vehicle navigation device 10 (that is, position information of the vehicle 60a) measured by the sensor unit 14 described later. The position information 121 may include not only information indicating the position where the position is determined, but also the time when the position is measured.
The identification information 122 is information for identifying the in-vehicle navigation device 10. As the identification information 122, for example, a serial number uniquely assigned to the in-vehicle navigation device 10 can be used. In addition, the telephone number assigned to the SIM (Subscriber Identity Module) inserted in the communication unit 13 in order for the communication unit 13 to connect to the communication network 50 such as a mobile phone network is used as the identification information 122. Can be used as In addition, a VIN (vehicle identification number) or a license plate number uniquely assigned to the vehicle 60 a can be used as the identification information 122.

Each piece of information stored in the storage unit 12 may be stored in the storage unit 12 in advance, or as necessary from a server device (not shown) connected to the communication network 50. May be downloaded as appropriate. Furthermore, it may be appropriately modified according to user input or the like.

The communication unit 13 has a DSP (Digital Signal Processor) or the like, and is compatible with other 3G (3rd Generation) LTE (Long Term Evolution) or Wi-Fi (registered trademark) standards via the communication network 50. Wireless communication with a device (for example, the information analysis device 30) is realized. For example, the communication unit 13 is used by a position information transmission unit 112 described later to transmit the position information 121 and the identification information 122 stored in the storage unit 12 to the information analysis device 30. However, data transmitted and received between the communication unit 13 and other devices is not particularly limited, and information other than the position information 121 and the identification information 122 may be transmitted and received.

The sensor unit 14 includes, for example, a GPS (Global Positioning System) sensor, a gyro sensor, an acceleration sensor, and the like. The sensor unit 14 has a function as position detecting means for detecting position information, receives a GPS satellite signal by a GPS sensor, and measures position information (latitude and longitude) of the in-vehicle navigation device 10. Positioning by the sensor unit 14 is performed at a predetermined time interval (for example, every 3 seconds) as described above. Positioned position information is stored in the storage unit 12 as position information 121.
Note that the sensor unit 14 can further increase the positioning accuracy of the position information of the in-vehicle navigation device 10 based on the angular velocity measured by the gyro sensor or the acceleration sensor or the acceleration.
In addition, when the GPS communication is difficult or impossible, the sensor unit 14 uses AGPS (Assisted Global Positioning System) communication, and the position information of the in-vehicle navigation device 10 based on the base station information acquired from the communication unit 13. Can also be calculated.

The display unit 15 is configured by a display device such as a liquid crystal display or an organic electroluminescence panel. The display unit 15 displays an image in response to an instruction from the control unit 11. Examples of the information displayed by the display unit 15 include the current position of the in-vehicle navigation device 10, map information around the current position of the in-vehicle navigation device 10 read from the map information, a destination set by the user, and other in-vehicle information. The waiting information notified from the navigation device 10, route information, various user interfaces, and the like can be mentioned.

The input unit 16 includes a physical switch called a numeric keypad, an input device (not shown) such as a touch panel provided on the display surface of the display unit 15, and the like. By outputting a signal based on an operation input from the input unit 16, for example, a numeric keypad pressed by the user or a touch on the touch panel, to the control unit 11, an operation such as a selection operation by the user or a map enlargement / reduction can be realized. it can.

In addition, although not shown, a speaker, a microphone, or the like can be provided. The speaker outputs a sound to the driver, and the microphone collects a sound emitted by the driver.
By doing so, it is also possible to output information from a speaker by voice, or to input various selections and instructions by a driver who are voice-input via a microphone to the control unit 11 by voice recognition technology.

Next, details of the control unit 11 will be described. The control unit 11 includes a microprocessor having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an I / O (Input / Output), and the like. The CPU executes each program read from the ROM or the storage unit 12, reads information from the RAM, ROM, and the storage unit 12 at the time of execution, and writes information to the RAM and the storage unit 12. It exchanges signals with the communication unit 13, the sensor unit 14, the display unit 15, and the input unit 16. In this way, the processing in this embodiment is realized by the cooperation of hardware and software (program).

The control unit 11 includes a route guide unit 111, a location information transmission unit 112, and a facility information acquisition unit 113 as functional blocks.

The route guidance unit 111 is a part that performs route guidance processing to a destination such as a facility input or selected by the user.
The route guidance process to the destination is equivalent to the route guidance process in a general car navigation system. That is, the route guidance unit 111 generates a map to the destination based on the map information (not shown) stored in the storage unit 12, and the vehicle-mounted navigation measured by the sensor unit 14 on this map. Route guidance can be performed by superimposing the current position of the device 10, the position of the destination, and the route information to the destination and displaying this on the display unit 15. In this case, route guidance sound may be output from a speaker (not shown). Alternatively, information on road congestion, weather information, and the like may be acquired through communication by the communication unit 13, and the acquired information may be used for route guidance processing.
Note that the route guidance processing to the destination is well known to those skilled in the art, and thus further detailed description is omitted.

The position information transmission unit 112 is a part that transmits the position information 121 and the identification information 122 stored in the storage unit 12 to the information analysis device 30 by wireless communication using the communication unit 13.
The position information transmission unit 112 transmits the position information 121 and the identification information 122 to the information analysis device 30 by turning on the ignition switch of the vehicle 60a (starting the engine) by the user who gets on the vehicle 60a. This is periodically performed after the automatic activation until the ignition switch of the vehicle 60a is turned off (the engine is stopped). For example, transmission is performed in real time whenever the sensor unit 14 performs positioning at a predetermined time interval (for example, every 3 seconds). Further, instead of transmitting to the information analysis device 30 in real time, a plurality of them are collected together (for example, the positional information 121 updated at intervals of 3 seconds and the identification information 122 are collected together for 3 minutes) and transmitted at a time. You may make it do. That is, so-called burst transmission may be performed. The length of the predetermined time interval and whether to transmit in real time or burst transmission can be arbitrarily set according to the environment to which the present embodiment is applied.
In this way, by performing real-time transmission or burst transmission, the position information transmission unit 112 obtains position information 121 for identifying the moving route of the vehicle 60a measured by the sensor unit 14 and identification information 122 as information. It transmits with respect to the analyzer 30.

In this case, the information switch is set with the position specified by the position information 121 measured immediately after the ignition switch is turned on (engine is started) and the in-vehicle navigation device 10 is automatically started as the first vehicle position, that is, the starting position. 30 can be transmitted. Furthermore, the position specified by the position information 121 measured immediately before the ignition switch is turned off (engine stop) can be transmitted to the information analysis apparatus 30 as the final vehicle position, that is, the parking position.
In this case, after adding the position information 121 indicating the departure position or the position information 121 indicating the stop position (for example, setting a flag indicating these to 1) to the position information 121. The information may be transmitted to the information analysis device 30. For the position information 121 (that is, the stop position) measured immediately before the ignition switch is turned off (engine stop), when the ignition switch is turned on (engine started) and the vehicle-mounted navigation device 10 is started again. May be sent to.

Even when burst transmission is performed, if the route guidance unit 111 determines that the vehicle 60a has arrived at a destination such as a facility, the position information transmission unit 112 performs transmission in real time. It is good to switch. In this way, after arriving at the destination such as the facility, before the location information 121 of the destination such as the facility is transmitted, the ignition switch is turned off (engine stopped), and the location of the destination such as the facility is detected. A situation in which the information 121 is not transmitted to the information analysis apparatus 30 can be prevented.

The facility information acquisition unit 113 receives and acquires distribution information about the facility from the information analysis device 30. And the facility information acquisition part 113 can provide a user with the facility information acquired from the information analysis apparatus 30, for example by outputting to the display part 15.
Specifically, the facility information acquisition unit 113 receives distribution information (hereinafter also simply referred to as “facility information”) regarding facilities distributed by the information analysis device 30 when the user drives the vehicle 60a and moves. And can be obtained.
As will be described later, the facility information acquisition unit 113 operates when the user drives the vehicle 60a and moves by the information analysis device 30 in the vicinity of the facility targeted for the distribution destination of the distribution information. Information for distribution may be received and acquired.

Note that the user of the vehicle 60 a may explicitly request whether or not to distribute facility information to the information analysis device 30. In this case, the facility information acquisition unit 113 may display, for example, a “facility information distribution start ON” button on the display unit 15 as illustrated in FIG. 3A. By doing so, when the facility information distribution start is turned on by a touch operation of the button by the user, the facility information acquisition unit 113 sends an information distribution start request to the information analysis device 30 via the communication unit 13. Can be configured to transmit to.
By doing so, the facility information acquisition unit 113 can receive and acquire the facility information distributed from the information analysis device 30. Note that the facility information acquisition unit 113 may receive and acquire facility information from the information analysis device 30 by turning on the default of facility information distribution start.

Based on the facility information acquired from the information analysis device 30, the facility information acquisition unit 113 displays the location of the facility distributed on the map around the current position of the vehicle 60a on the display unit 15, for example, as shown in FIG. 3B. Can be displayed. Further, the facility information is displayed on the display unit 15 as shown in FIG. 3C. 3B and 3C exemplify a case where there is one facility, but when distribution information related to a plurality of facilities is distributed, the facility information acquisition unit 113 is operated by a user's screen switching operation or the like. By displaying the facility information in a scrollable manner on the display unit 15, the user may be allowed to select a facility that he / she wants to visit.
The configuration of the in-vehicle navigation device 10 has been described above.

<Functional blocks provided in the mobile terminal 20>
Next, functional blocks provided in the mobile terminal 20 will be described with reference to the block diagram of FIG.
Here, the vehicle-mounted navigation device 10 described above receives power supply from the vehicle 60a, but the mobile terminal 20 receives power supply from a battery (not shown) included in the mobile terminal 20 itself. However, the portable terminal 20 may be supplied with power from a cigar socket or the like of the vehicle 60b in order to charge the battery.

As shown in FIG. 4, the mobile terminal 20 includes a control unit 21, a storage unit 22, a communication unit 23, a sensor unit 24, a display unit 25, an input unit 26, and a short-range communication unit 27. Consists of.
Here, the control unit 21, the storage unit 22, the communication unit 23, the sensor unit 24, the display unit 25, and the input unit 26 have functions equivalent to the functional blocks of the same name included in the in-vehicle navigation device 10 described above. Have. That is, by replacing the term “in-vehicle navigation device 10” in the description of the in-vehicle navigation device 10 with “portable terminal 20”, the description of each functional block of the portable terminal 20 will be omitted. To do.

On the other hand, since the mobile terminal 20 is different from the vehicle-mounted navigation device 10 in that it includes the short-range communication unit 27, the difference will be described below.
The near field communication unit 27 performs non-contact near field communication based on standards such as NFC (Near Field Communication) and Bluetooth (registered trademark), or wired near field communication via a USB (Universal Serial Bus) cable or the like. It is a part for.
On the other hand, the vehicle 60 b includes a near field communication unit for communicating with the near field communication unit 27. For example, the ECU (Electronic Control Unit) of the vehicle 60b includes a short-range communication unit.
And the case where the portable terminal 20 can communicate with ECU by near field communication is a case where the portable terminal 20 exists in the vehicle 60b. In this case, the position information measured by the sensor unit 24 of the mobile terminal 20 corresponds to the position information of the vehicle 60b.

Therefore, the mobile terminal 20 activates the position information transmission unit 212 while it can perform near field communication with the ECU via the near field communication unit 27. Then, the activated position information transmission unit 212 is similar to the position information transmission unit 112 of the in-vehicle navigation device 10, and the position information 221 for identifying the movement route of the vehicle 60 b measured by the sensor unit 24 and the identification information 222. Is transmitted to the information analysis device 30.

For example, when the user has the mobile terminal 20 and gets on the vehicle 60b and turns on the start switch of the vehicle 60b such as an ignition switch, the vehicle 60b and the mobile terminal 20 are connected (paired), and the mobile terminal 20 Positioned position information 221 and identification information 222 are transmitted from the portable terminal 20 to the information analysis device 30. In this case, the position specified by the position information 121 measured immediately after the pairing of the vehicle 60b and the portable terminal 20 can be transmitted to the information analysis apparatus 30 as the first vehicle position, that is, the starting position.

Further, when the start switch of the vehicle 60b such as an ignition switch is turned off, the pairing between the vehicle 60b and the portable terminal 20 is released. In this case, the position specified by the position information 121 measured immediately before being released can be transmitted to the information analysis apparatus 30 as the final vehicle position, that is, the parking position.
In this case, transmission may be performed in real time, burst transmission may be performed, burst transmission may be switched to real time transmission when it is determined that the destination has been reached, or departure position Or the point which may add the information which shows that it is a parking position, and the point which may transmit a parking position at the time of restart are the same as that of the position information transmission part 112.

When the vehicle 60b has a function of positioning position information, the position information measured by the vehicle 60b is transmitted to the information analysis apparatus 30 as position information 121 instead of the position information measured by the sensor unit 24. You may do it. In this case, the sensor unit 24 may be omitted from the mobile terminal 20.

The position information database 322 is constructed by a position information database creation unit 311 described later. Details of the position information database 322 will be described later when the position information database creation unit 311 is described. In the following description, when the position information 121 and the position information 221 are described without being distinguished, the reference numerals are omitted and referred to as “position information”. Similarly, when the identification information 122 and the identification information 222 are described without being distinguished, the reference numerals are omitted and referred to as “identification information”.

The facility information 323 includes facility identification information (facility ID), a name, and a category regarding the facility as basic information, and also includes distribution facility information 3231 (not shown) regarding the facility.
The distribution facility information 3231 may include, for example, in addition to basic information, a telephone number, an address, business hours, a menu provided if the facility is a restaurant, facility information regarding merchandise services, facility advertisement information, and the like. Good. Further, the distribution facility information 3231 may include facility privilege information (for example, discount information on products or services, coupon information, or point information).
Further, the distribution facility information 3231 related to the facility may be stored in advance, or may be appropriately created and updated as necessary from a terminal device (not shown) connected to the communication network 50 or the like. . In particular, the distribution facility information 3231 may be configured so as to be appropriately created and updated from a terminal device (not shown) installed in the facility, for example, according to the input of the manager of the facility.

Here, the categories related to facilities will be explained. Generally, categories are set according to things and services provided at the facility. The present invention collects a list of visit facilities for each category in a plurality of categories created for each mobile user and performs clustering processing on the mobile user to which cluster the mobile user is classified. An attribute (profile) indicating is assigned. Therefore, it is assumed that information distribution with higher accuracy can be performed based on attributes obtained by clustering processing based on the mobile facility visit facility list created for each category in a plurality of categories.

For example, assuming that a store (facility) that handles babies and infant products and services for babies and infants is one category (assuming “category A”), a mobile user who visits a facility belonging to category A is: It is assumed that the family mainly has babies and infants, or a family where babies are born soon.

Also, assuming that the restaurant is one category (category B), it is assumed that the mobile user who visits the family restaurant, which is one of the facilities belonging to category B, is mainly the family layer. On the other hand, it is assumed that a mobile user who visits a fast food restaurant such as a beef bowl chain store that is one of the facilities (stores) belonging to category B is mainly a single person.

If a clothing store is one category (Category C), SPA (Specialty 属 す る store retailer of Private label Apparel = manufacturing and retail) and fast fashion chain stores are one of the facilities (stores) belonging to Category C. The user of the mobile body who visits is assumed to be a middle class family or a single person. On the other hand, a mobile user who visits a brand specialty store, a brand outlet facility, or the like is assumed to be a small wealthy group with a strong interest in fashion.

Then, for example, clustering processing is performed on all mobile users who have visited from cluster A to cluster C based on the visit facility list for each category, so that the attributes of each cluster of mobile users Can be typified.
For example, a user of a mobile who likes to visit a specific store belonging to category A, visits a specific family restaurant belonging to category B, and visits a specific SPA belonging to category C may From this, it is presumed that the visiting facility preference for category C is assigned to one category in the middle class of young families with similarities.
In addition, facilities belonging to category A have almost no visit history, and prefer to visit a specific fast food restaurant such as a beef bowl chain store belonging to category B, and store specific brand specialty stores or brand outlets belonging to category C. It is estimated that the user of the mobile body who likes a facility or the like is assigned to one category of a single small rich person who has similar preferences of the visiting facility regarding the category A to the category C.

Then, for example, a cram school chain store whose price is lower than the average designates a cluster of the above-mentioned “young family middle class” and relates to the facility to a mobile user belonging to the cluster. By distributing the facility information, it becomes possible to perform a targeting advertisement with higher accuracy.
As mentioned above, although the usefulness of this invention was demonstrated giving some examples, this invention is not restricted to these illustrated categories. In all categories, classification by clustering processing based on the visited facility list does not use sensitive data such as questionnaires from customers, so the person in charge of the facility who wants to distribute facility information can feel at ease. The effect that it can be used is produced.

The communication unit 33 includes a DSP (Digital Signal Processor) and the like, and is compliant with standards such as 3G (3rd Generation) and Wi-Fi (registered trademark), and is connected to other communication units via the communication network 50 via the communication network 50. Wireless communication with the device is realized. The communication unit 33 is used, for example, to receive position information and identification information transmitted from each of the in-vehicle navigation device 10 and the mobile terminal 20. Moreover, the communication part 33 is utilized in order to transmit facility information with respect to each of the vehicle-mounted navigation apparatus 10 and the portable terminal 20, for example.
However, data transmitted and received between the communication unit 33 and other devices is not particularly limited, and information other than these pieces of information may be transmitted and received.
The display unit 35 is configured by a display device such as a liquid crystal display or an organic electroluminescence panel. The display unit 35 displays an image in response to an instruction from the control unit 31.
The input unit 36 includes an input device (not shown) such as a touch panel provided on a display surface of the keyboard or the display unit 35. By outputting a signal based on an operation input from the input unit 36, for example, a key press by the operator or a touch on the touch panel, to the control unit 31, an operation such as an input operation or a selection operation by the operator can be realized.

Next, details of the control unit 31 will be described. The control unit 31 includes a microprocessor having a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), and an input / output (I / O). The CPU executes each program read from the ROM or the storage unit 32, reads information from the RAM, ROM, and the storage unit 32 at the time of execution, and writes information to the RAM and the storage unit 32. It exchanges signals with the communication unit 33, the sensor unit 34, the display unit 35, and the input unit 36. In this way, the processing in this embodiment is realized by the cooperation of hardware and software (program).
Thus, the control unit 31 causes the information analysis apparatus 30 to function as predetermined means (hereinafter collectively referred to as “information analysis control unit”) by executing each program.
Further, the control unit 31 causes the information analysis apparatus 30 to execute predetermined steps (hereinafter collectively referred to as “information analysis control step”) by executing each program.
Hereinafter, functions of the control unit 31 will be described from the viewpoint of the information analysis control unit. Note that the description based on the viewpoint of the information analysis control step (method) can be described by substituting “step” with “part”, and thus will be omitted.

The control unit 31 includes a location information database creation unit 311, a mobile visit determination unit 312, a visit facility list creation unit 313, a clustering processing unit 314, and a facility information distribution unit 315 as functional blocks.

<Position information database creation unit 311>
The position information database creation unit 311 receives identification information, position information, time information, and the like of the vehicle 60 from each vehicle 60 via the communication unit 33. Furthermore, the location information database creation unit 311 constructs the location information database 322 based on the identification information, location information, time information, and the like received from each vehicle 60, and appropriately creates and updates it. Before describing the position information database creation unit 311, an example of the data structure of the position information database 322 will be described first.

[About Location Information Database 322]
As shown in FIG. 6, the position information database 322 includes “position information” and “identification information” received from each of the in-vehicle navigation device 10 and the mobile terminal 20 as described above.
Specifically, position information, time information, and the like periodically transmitted from when the vehicle 60 is turned on until when the vehicle is turned off (that is, from departure to arrival) are managed for each identification information of the vehicle 60. It is stored in a movement history record (not shown). In this way, the movement history record stores information on the current position that is sequentially received from the vehicle 60. The reception may be received once every few seconds or stored in time series on the vehicle 60 side and received together at a certain time or when the application is activated on the vehicle 60 side. May be. In addition, you may make it memorize | store a movement history record as a temporary record of the positional infomation database 322 as a record in which a visiting facility is undetermined.
For the departure facility ID corresponding to the departure position and the visit facility ID corresponding to the arrival position, the departure position and the arrival position are respectively converted into map information based on the map information 321 and the facility position information in the storage unit 32. The departure facility ID and the arrival facility ID can be specified by comparing with the included facility information.
When the vehicle is ignited off, the travel history record is stored as a record in the location information database including the visited facility information by determining the visited facility as the arrival position.
The location information database 322 is identified by the location information database creation unit 311 based on the “location information” received from each of the in-vehicle navigation device 10 and the mobile terminal 20 as described above. including. As described above, the “visiting facility” includes undetermined data when the vehicle 60 is moving.
Then, the location information database creation unit 311 constructs and updates the location information database 322 by storing information corresponding to each attribute in the field.

Here, the “visit facility” in the position information database 322 is information for identifying a place where the user has arrived and stayed with the vehicle 60 (for example, a facility such as a store) except when the vehicle 60 is moving. is there. When the vehicle 60 is turned off, the location information database creation unit 311 can specify the visiting facility from the location information received together with the identification information. For example, as described above, consider a case where the position information includes information indicating the parking position. In this case, the parking position is compared with the position of each facility included in the map information 321 (and the position of the parking lot associated with the facility), and the specified parking position and the position of any facility (and the facility) If the locations of the parking lots associated with each other match, it is determined that the user has arrived at this facility by the vehicle 60 and stayed there.
Then, the facility identification information (facility ID) included in the map information 321 is stored in the visited facility field in the location information database 322.

In addition, if the position information does not include information indicating the parking position, for example, the position corresponding to the position information received last until the transmission of the position information is terminated, It is also possible to identify a visiting facility by regarding a position that does not change over time as a parking position and comparing it with the position of each facility (and the position of the parking lot associated with the facility).
Further, if the position information does not include information indicating the parking position, for example, a facility set as a destination in route guidance can be specified as a visiting facility.

Note that the degree of “coincidence” between the parking position described above and the facility position may be arbitrarily determined. For example, when the in-vehicle navigation device 10 or the mobile terminal 20 can measure the position information with high accuracy, the range for determining coincidence may be narrowed. On the other hand, when the in-vehicle navigation device 10 and the portable terminal 20 cannot measure the position information with high accuracy, the range for determining the coincidence may be widened. In other words, it may be determined that there is a match even when the position is slightly shifted.

Further, the “identification information” in the position information database 322 is information for identifying the in-vehicle navigation device 10 or the portable terminal 20 that is the transmission source of the position information as described above. That is, the information identifies the vehicle 60 corresponding to the in-vehicle navigation device 10 or the mobile terminal 20. The position information database creation unit 311 stores the identification information received together with the position information in the field.

The “departure position” in the position information database 322 is a departure position on the movement route when moving to the visited facility.
The location information database creation unit 311 identifies the departure location from the location information received together with the identification information. For example, as described above, if the position information includes information indicating the starting position, the starting position is specified by this information. In addition, if the position information does not include information indicating the departure position, for example, the position corresponding to the first received position information from the start to the end of transmission of the position information is the departure position. Can also be considered.
The location information database creation unit 311 identifies whether the departure location is a facility (and a parking lot linked to the facility) included in the map information 321 based on the departure location identified in this way. be able to.

Also, the “position information” in the position information database 322 is all position information that changes discretely in time from the departure position to the parking position on the travel route when visiting the visited facility. In the “location information” in the location information database 322, the location information from the first departure location to the visiting facility is linked and stored. The position information database creation unit 311 stores all received position information in the field from the start to the end of transmission of position information.

The position information database creation unit 311 is created based on the received position information and identification information from the start to the end of transmission of the position information and identification information from any of the in-vehicle navigation device 10 and the mobile terminal 20. The position information database 322 is updated based on the movement history record to be performed.

<Mobile Object Visit Determination Unit 312>
Next, the mobile visit determination unit 312 will be described.
The mobile body visit determination unit 312 can create and store the mobile body visit data of the vehicle 60 by referring to the past movement history of the position information in the position information database 322 based on the identification information of the vehicle 60. it can.
More specifically, the mobile visit determination unit 312 visited the vehicle 60 during a predetermined period set in advance, for example, 3 months, 6 months, or 12 months, based on the position information database 322. Extract all facilities. Then, mobile visit data for visits to all facilities visited within a predetermined period is created and stored in the storage unit 32. The predetermined period is not limited to 3 months, 6 months or 12 months. It can be arbitrarily set based on the characteristics of facilities belonging to the category.
The mobile body visit determination unit 312 may create mobile body visit data in which detailed data such as a visit date and time and a stay time is added to the category to which the facility belongs and the name of the facility as the facility information.

<Visit facility list creation unit 313>
Next, the visiting facility list creation unit 313 will be described.
The visited facility list creation unit 313 is a list of facilities for each category visited within a predetermined period (by category) based on the mobile visit data for each vehicle 60 (mobile) created by the mobile visit determination unit 312. (Visit facility list) is created and stored in the storage unit 32, for example. Note that the category-specific visited facility list may be listed in descending order of the number of visits.
Note that the visited facility list creation unit 313 may create a visited facility list for each category by adding detailed data such as the visit date and time and stay time to the name of the visited facility.

<Clustering processing unit 314>
The clustering processing unit 314 accumulates the visit facility list for each category in the plurality of categories of the vehicle 60 (moving body) created and stored by the visit facility list creation unit 313, and moves based on the accumulated visit facility list. A clustering process for clustering the users of the body is performed. By doing so, it is possible to attach the same attribute label to users of mobile objects belonging to the same cluster.
Note that clustering is a so-called “unsupervised data classification method” that automatically classifies without external criteria. In the present embodiment, the clustering by category will be briefly described by taking an example of clustering by the K-means method, which is a known non-hierarchical technique. A technique related to clustering is known to those skilled in the art, and a known clustering technique other than the K-means method, not limited to the K-means method, may be applied.

An example of the feature vector of the visited facility list will be described.
The clustering processing unit 314 acquires a visited facility list of each moving body (vehicle 60) related to a plurality of categories stored in the storage unit 32. Here, a total of N mobile bodies (vehicles 60) have visited any facility belonging to a plurality of categories.
The clustering processing unit 314 generates a feature vector using the category-specific visited facility list of each moving object i (1 ≦ i ≦ N). For this reason, the clustering processing unit 314 has previously visited a facility belonging to the plurality of categories within the predetermined period for the clustering process, and the total number of visiting facilities of the moving object is, for example, a predetermined threshold value or more. It is preferable to prepare a list relating to M facilities (M is an arbitrary natural number) j (1 ≦ j ≦ M). Thereby, by excluding the data of the facility having a small total number of visits of the mobile object i (1 ≦ i ≦ N) (that is, the facility having a small number of visits by the user of the mobile object within a predetermined period) as noise, Processing time can be shortened.
Then, the number of times n (i, j) (0 ≦ n) that the mobile object i (1 ≦ i ≦ N) visited the facility j (1 ≦ j ≦ M) is the feature of the mobile object i (1 ≦ i ≦ N). A feature vector as a vector (i, j) can be generated.
Note that the feature vector shown above is merely an example, and the present invention is not limited to this. For example, when the mobile object i (1 ≦ i ≦ N) has visited the facility j (1 ≦ j ≦ M), the feature quantity (i, j) = 1 is set, and the mobile object i (1 ≦ i ≦ N) is set. If N) has never visited the facility j (1 ≦ j ≦ M), a feature vector with the feature quantity (i, j) = 0 of the moving object i (1 ≦ i ≦ N) may be generated. . Alternatively, a threshold may be set in advance for the number of visits, and the feature amount (i, j) = 1 may be set when the number of visits to the facility j is equal to or greater than the threshold, for example. In addition, the feature vector of each mobile object i (1 ≦ i ≦ N) may be generated from the category-specific visited facility list of each mobile object i (1 ≦ i ≦ N) by an arbitrary method.

Next, the clustering processing unit 314 sets a predetermined number of clusters in order to cluster the moving object i (1 ≦ i ≦ N) based on the feature vector, and each cluster (“ The initial value of the representative vector of the unit is also set.
Thereafter, the clustering processing unit 314 makes each mobile object i (1 ≦ i ≦ N) so that the distance (for example, Euclidean distance) between the feature vector and the representative vector of each mobile object i (1 ≦ i ≦ N) is minimized. ) Is distributed to one of a plurality of units.
Thereafter, the clustering processing unit 314 calculates a new representative vector for each unit based on the feature vector of the moving object i (1 ≦ i ≦ N) distributed to each unit. Based on the new representative vector, the clustering processing unit 314 makes each moving object i (1 ≦ i ≦ N) such that the distance between the feature vector of each moving object i (1 ≦ i ≦ N) and the representative vector is minimized. N) feature vectors are assigned to any of a plurality of units. In this case, when unit reassignment is performed, the clustering processing unit 314 determines a new representative of the unit based on the feature vector of the moving object i (1 ≦ i ≦ N) assigned to each unit. A vector is calculated, and the feature vector of each moving object i (1 ≦ i ≦ N) is distributed to any of a plurality of units based on the new representative vector as described above. By repeating such processing, the clustering processing unit 314 can complete clustering when unit reassignment is not performed.
It is assumed that the feature vectors of the moving objects having similar visiting facilities in each category are close to each other. From this, it can be expected that the moving objects having similar visiting facilities in each category are distributed to the same cluster by the clustering process described above.

In this way, the clustering processing unit 314 accumulates the visiting facility list for each category in the plurality of categories of the vehicle 60 (moving body) created and stored by the visiting facility list creating unit 313 from the plurality of moving bodies, By clustering the visiting facility list for each category in the plurality of categories, it is possible to perform a clustering process in which the same attribute label is assigned to the users of mobile objects distributed to the same cluster. As described above, the illustrated clustering process is an example, and the present invention is not limited to this. By applying a known clustering technique, a list of visiting facilities for each category in a plurality of categories of the vehicle 60 (mobile body) is accumulated from a plurality of mobile bodies, and the visiting facility list is clustered to obtain the same You may make it attach | subject the same attribute label with respect to the user of the mobile body distributed to a cluster.
In this way, by analyzing the visiting facility list for each category in a plurality of categories of the moving body, the same cluster of users having similar facilities to be visited in each category of the plurality of categories of the user of the moving body. Can be sorted. By doing so, it is possible to obtain profiling data representing the attributes of the users of the mobile objects distributed to the same cluster. That is, user profiling data can be obtained only from floating car data without using sensitive data such as Internet search history and mail contents.

<Facility information distribution unit 315>
The facility information distribution unit 315 uses the clustering processing unit 314 to distribute information targeting mobile users who have been classified into each cluster because the visiting facilities in a plurality of categories are similar. Can be delivered.
More specifically, the facility information distribution unit 315 indicates that the user of the mobile body belonging to each cluster calculated by accumulating the visiting facility list for each category in the plurality of categories is the preference of the facility to visit in the plurality of categories. Therefore, for example, when an arbitrary cluster is designated via the input unit 36, distribution information can be distributed targeting a mobile user belonging to the cluster. .
Referring to the above-mentioned example (category A, category B, category C), for example, a cram school chain store whose price is lower than the average is similar to that of the above-mentioned young family whose visitor facility preferences for category A to category C are similar. By specifying a middle-tier cluster and distributing facility information regarding the learning cram chain store to mobile users belonging to the cluster, it becomes possible to perform a targeting advertisement with higher accuracy.
By doing so, it is possible to provide targeting advertisements according to the preferences (characteristics) of the mobile user in a plurality of categories, so that the mobile user who has received the distribution information of the facility feels bothersome Less.
In the above example, a mode in which a public relations person (operator) designates a predetermined cluster via the input unit 36 is exemplified, but the present invention is not limited to this. For example, although not shown, a predetermined cluster may be designated via a terminal device that is communicably connected to the information analysis device 30.
When a predetermined cluster is designated, for example, a cluster attribute list (or a visiting facility list) or the like may be displayed on the display unit 35 and selected from the attribute list.

As described above, the embodiments of the functional units of the information analysis system 1 of the present invention have been described based on the configurations of the in-vehicle navigation device 10, the mobile terminal 20, and the information analysis device 30 mounted on the vehicle 60. In addition, the embodiment of each functional unit included in the information analysis apparatus 30 according to the present invention may be distributed in a single computer or a large number of computers in one place or distributed in several places and interconnected by a communication network. Can be deployed to run. It can also be configured using a plurality of virtual computers on the cloud.

Next, the position information transmission unit 112 determines whether or not to end the transmission of the position information (step S15). As described above, transmission ends when the ignition switch of the vehicle 60a is turned off. If the ignition switch of vehicle 60a remains on (No in step S15), the positioning in step S12, the transmission in step S13, and the creation and update of the movement history record in position information database 322 in step S14 are repeated.

On the other hand, when the ignition switch of the vehicle 60a is turned off (Yes in step S15), the process proceeds to step S16.

In step S <b> 16, the location information database creation unit 311 of the information analysis device 30 updates the location information database 322 (visit facility) by determining the visited facility of the movement history record when transmission of the location information ends.

Next, operations for collecting location information and updating the location information database for the mobile terminal 20 will be described. As for the portable terminal 20, in the above description, the position information transmission unit 112 is replaced with the position information transmission unit 212, the sensor unit 14 is replaced with the sensor unit 24, and the criterion of Yes in step S11 is “vehicles such as an ignition switch”. 60b is turned on and the vehicle 60b and the portable terminal 20 are paired ", and the criterion of Yes in step S14 is" the start switch of the vehicle 60b such as an ignition switch is turned off and the vehicle 60b and the portable terminal 20 are carried. " It may be replaced with “when pairing of terminal 20 is released”. Therefore, the overlapping description is omitted.

Next, with reference to the flowchart of FIG. 8, the operation | movement at the time of the cluster analysis (clustering process) regarding the mobile body user (user of the vehicle 60) by the information analysis apparatus 30 is demonstrated.

In step S21, the visited facility list creation unit 313 extracts movement history records of a plurality of vehicles 60 within a predetermined period from the position information database 322.

In step S22, the visited facility list creation unit 313 creates and stores a visit facility list for each category visited by each vehicle 60 within a predetermined period based on the extracted movement history records of the plurality of vehicles 60.

In step S23, the clustering processing unit 314 performs cluster analysis by accumulating the visiting facility lists for each category.

In step S24, the clustering processing unit 314 attaches the same attribute label to the users of mobile objects distributed to the same cluster by accumulating the visiting facility lists for each category and clustering them.

As described above, by performing a cluster analysis on the visit facility list for each category in a plurality of categories of each mobile body (vehicle 60), users who are similar to the facility to be visited in each category of the plurality of categories of the user of the mobile body Can be distributed to the same cluster. The attribute of each cluster obtained by the clustering process as described above can be given to the user of the mobile object distributed to the cluster.

According to the present embodiment described above, it is possible to easily grasp a mobile user's preference as a categorized lump by performing cluster analysis on a facility visited by a plurality of mobile objects, and thus the mobile object It becomes possible to provide a targeting advertisement in accordance with user preferences (characteristics).
In the present embodiment, the clustering process based on the visited facility list for each category in the plurality of categories of the vehicle 60 (mobile body) is exemplified, but the present invention can also be applied to the clustering process based on the visited facility list in one category.
