The communication unit 13 is used, for example, by the position information transmission unit 112, which will be 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, there is no particular limitation on the data transmitted / received between the communication unit 13 and other devices, and information other than the position information 121 and the identification information 122 may be transmitted / received.

The sensor unit 14 is composed of, for example, a GPS (Global Positioning System) sensor, a gyro sensor, an acceleration sensor, or the like. The sensor unit 14 has a function as a position detection means for detecting position information, receives GPS satellite signals by a GPS sensor, and positions the position information (latitude and longitude) of the vehicle-mounted navigation device 10. Positioning by the sensor unit 14 is performed at predetermined time intervals (for example, 3 second intervals) as described above. The positioned position information is stored in the storage unit 12 as the position information 121.
The sensor unit 14 can further improve the positioning accuracy of the position information of the in-vehicle navigation device 10 based on the angular velocity measured by the gyro sensor and the acceleration sensor and the acceleration.
Further, when GPS communication becomes 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 is based on the base station information acquired from the communication unit 13. It is also possible to calculate.

The display unit 15 is composed of 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. The information displayed by the display unit 15 includes, for example, the current position of the vehicle-mounted navigation device 10, map information around the current position of the vehicle-mounted navigation device 10 read from the map information, a destination set by the user, and other vehicle-mounted information. Examples include the meeting information, route information, and various user interfaces notified from the navigation device 10.

The input unit 16 is composed of 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. By outputting an operation input from the input unit 16, for example, a user pressing the numeric keypad or a signal based on the touch of the touch panel to the control unit 11, it is possible to realize an operation such as a selection operation by the user or enlargement / reduction of a map. can.

In addition, although not shown, a speaker, a microphone, or the like may be provided. The speaker outputs voice to the driver, and the microphone collects voice and the like emitted by the driver.
By doing so, the information can be output by voice from the speaker, and various selections and instructions by the driver input by voice through the microphone can be input to the control unit 11 by the voice recognition technique.

Next, the details of the control unit 11 will be described. The control unit 11 is composed of 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, writes information to the RAM and the storage unit 12, 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. Then, in this way, the processing in the present embodiment is realized by the cooperation of the hardware and the software (program).

The control unit 11 includes a route guidance unit 111, a position 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 positioned on this map by the sensor unit 14. 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, further, the voice for route guidance may be output from the speaker (not shown). Further, information on road congestion status, weather information, and the like may be acquired by communication by the communication unit 13, and the acquired information may be used for route guidance processing.
Since the route guidance process to the destination is well known to those skilled in the art, further detailed description will be omitted.

The position information transmission unit 112 is a unit 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.
In the transmission of the position information 121 and the identification information 122 to the information analysis device 30 by the position information transmission unit 112, the ignition switch of the vehicle 60a is turned on (the engine is started) by the user who got on the vehicle 60a, and the vehicle-mounted navigation device 10 is used. It is periodically performed from the automatic start until the ignition switch of the vehicle 60a is turned off (the engine is stopped). For example, each time the sensor unit 14 performs positioning at a predetermined time interval (for example, every 3 seconds), transmission is performed in real time. Further, instead of transmitting to the information analyzer 30 in real time, a plurality of pieces (for example, the position information 121 updated at 3 second intervals in 3 minutes and the identification information 122 are collectively transmitted) are transmitted at once. You may try to do it. That is, so-called burst transmission may be performed. The length of the predetermined time interval and whether to perform real-time transmission or burst transmission can be arbitrarily set according to the environment to which the present embodiment is applied and the like.
By performing real-time transmission and burst transmission in this way, the position information transmission unit 112 provides information on the position information 121 and the identification information 122 for specifying the movement route of the vehicle 60a positioned by the sensor unit 14. It is transmitted to the analyzer 30.

In this case, the information analysis device uses the position specified by the position information 121 determined immediately after the ignition switch is turned on (engine is started) and the vehicle-mounted navigation device 10 is automatically started as the first vehicle position, that is, the departure position. It can be transmitted to 30. Further, the position specified by the position information 121 determined immediately before the ignition switch is turned off (engine stopped) can be transmitted to the information analysis device 30 as the final vehicle position, that is, the parking position.
In this case, after adding the information indicating that the position information 121 indicates the departure position or the position information 121 indicating the stop position (for example, the flag indicating these is set to 1) to the position information 121. , May be sent to the information analyzer 30. Regarding the position information 121 (that is, the stop position) positioned immediately before the ignition switch is turned off (engine stopped), when the ignition switch is turned on (engine started) and the in-vehicle navigation device 10 is restarted. May be sent to.

Further, even in the case of burst transmission, 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 shall transmit in real time. You should switch. In this way, after arriving at the destination of the facility or the like and before the position information 121 of the destination of the facility or the like is transmitted, the ignition switch is turned off (engine stopped) and the position of the destination of the facility or the like is reached. It is possible to prevent the situation where the information 121 is not transmitted to the information analyzer 30.

The facility information acquisition unit 113 receives and acquires distribution information about the facility from the information analysis device 30. Then, the facility information acquisition unit 113 can provide the facility information acquired from the information analysis device 30 to the user, for example, by outputting the facility information to the display unit 15.
Specifically, the facility information acquisition unit 113 receives distribution information (hereinafter, also simply referred to as “facility information”) regarding the facility distributed by the information analysis device 30 when the user drives and moves the vehicle 60a. Can be obtained.
As will be described later, when the user drives the vehicle 60a and the information analyzer 30 moves in the vicinity of the facility where the user is the target of the distribution destination of the distribution information, the facility information acquisition unit 113 is the facility. It is also possible to receive and acquire the distribution information regarding.

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

Based on the facility information acquired from the information analyzer 30, the facility information acquisition unit 113 displays the position 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, as shown in FIG. 3C, the facility information is displayed on the display unit 15. In addition, although the case where there is one facility is illustrated in FIGS. 3B and 3C, when the distribution information regarding a plurality of facilities is distributed, the facility information acquisition unit 113 may perform a screen switching operation or the like by the user. By displaying the facility information on the display unit 15 in a scrollable manner, the user may be made to select the facility he / she wants to stop by.
The configuration of the vehicle-mounted navigation device 10 has been described above.

<Functional block of mobile terminal 20>
Next, the functional block included 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 is supplied with power from the vehicle 60a, but the mobile terminal 20 is supplied with power from its own battery (not shown). However, the mobile 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 the same functions as the functional blocks of the same name included in the in-vehicle navigation device 10 described above. Have. That is, by replacing the wording of the "vehicle-mounted navigation device 10" in the above-mentioned description of the vehicle-mounted navigation device 10 with the "mobile terminal 20", the description of each functional block of the mobile terminal 20 is obtained. do.

On the other hand, the mobile terminal 20 is different from the in-vehicle navigation device 10 in that it includes the short-range communication unit 27 and the like, and this difference will be described below.
The short-range communication unit 27 performs non-contact short-range communication conforming to standards such as NFC (Near Field Communication) and Bluetooth (registered trademark), or wired short-range communication via a USB (Universal Serial Bus) cable or the like. It is a part for.
On the other hand, the vehicle 60b includes a short-range communication unit for communicating with the short-range communication unit 27. For example, the ECU (Electronic Control Unit) of the vehicle 60b includes a short-range communication unit.
The case where the mobile terminal 20 can communicate with the ECU by short-range communication is a case where the mobile terminal 20 is present in the vehicle 60b. In this case, the position information determined 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 the mobile terminal 20 can perform short-range communication with the ECU via the short-range communication unit 27. Then, the activated position information transmission unit 212 has the position information 221 and the identification information 222 for specifying the movement route of the vehicle 60b positioned by the sensor unit 24 in the same manner as the position information transmission unit 112 of the in-vehicle navigation device 10. Is transmitted to the information analyzer 30.

For example, when a user possesses a mobile terminal 20 and gets on a vehicle 60b and turns on an activation 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 is connected. The positioned position information 221 and the identification information 222 are transmitted from the mobile terminal 20 to the information analyzer 30. In this case, the position specified by the position information 121 determined immediately after the pairing of the vehicle 60b and the mobile terminal 20 can be transmitted to the information analysis device 30 as the first vehicle position, that is, the departure position.

Further, when the activation switch of the vehicle 60b such as the ignition switch is turned off, the pairing between the vehicle 60b and the mobile terminal 20 is released. In this case, the position specified by the position information 121 positioned immediately before the release can be transmitted to the information analysis device 30 as the final vehicle position, that is, the parking position.
In this case, the point may be transmitted in real time or burst transmission, the point that burst transmission may be switched to real-time transmission when it is determined that the destination has arrived, and the departure position. Alternatively, the point that information indicating that the parking position may be added and the point that the parking position may be transmitted at the time of restart are the same as those of the position information transmitting unit 112.

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

Similarly, when the identification information 122 and the identification information 222 are described without distinction, the reference numerals are omitted and they are referred to as "identification information".

The facility information 323 includes facility identification information (facility ID), name, and facility-related category as basic information, and also includes distribution facility information 3231 (not shown) regarding the facility.
The distribution facility information 3231 may include, for example, a telephone number, an address, business hours, a menu provided if the facility is a restaurant, facility information related to products and services, facility advertisement information, and the like, in addition to basic information. good. Further, the distribution facility information 3231 may include facility privilege information (for example, discount information of goods or services, coupon information, point information, etc.).
Further, the distribution facility information 3231 regarding the facility may be stored in advance, or may be appropriately created and updated 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 that it can be appropriately created and updated according to the input of the administrator of the facility, for example, from a terminal device (not shown) installed in the facility.

Here, the categories related to facilities will be described. Generally, categories are set according to the goods and services provided by the facility. The present invention collects a list of visiting facilities for each category in a plurality of categories created for each user of the mobile body, and clusters the user of the mobile body to determine which cluster the user of the mobile body is classified into. Attribute (profile) indicating is given. Therefore, it is expected that more accurate information distribution will be possible based on the attributes obtained by clustering processing based on the visiting facility list of the moving object created for each category in a plurality of categories.

For example, if a store (facility) that handles products for babies and toddlers and services for babies and toddlers is set as one category (assumed to be "category A"), a mobile user who visits a facility belonging to category A It is assumed that the family mainly has babies and toddlers, or the family will soon have a baby.

Further, when the restaurant is set to one category (category B), it is assumed that the mobile user who visits the family restaurant, which is one of the facilities belonging to the category B, is mainly a family group. On the other hand, it is assumed that the mobile user who visits a fast food restaurant such as a gyudon chain store, which is one of the facilities (stores) belonging to category B, is mainly a single person.

If the clothing store is one category (category C), it is one of the facilities (stores) belonging to category C, such as SPA (Specialty store retailer of Private label Apparel) and fast fashion chain stores. The mobile users who visit the store are assumed to be middle-class families and singles. On the other hand, mobile users who visit brand specialty stores and brand outlet facilities are expected to be small rich people who have a strong interest in fashion.

Then, for example, by performing clustering processing for all the mobile users who visited from cluster A to cluster C based on the visited facility list for each category, the attributes of each cluster of the mobile users can be used. Can be categorized.
For example, a mobile user who prefers to visit a specific store belonging to category A, preferentially visits a specific family restaurant belonging to category B, and preferentially visits a specific SPA belonging to category C is category A. It is presumed from this that the tastes of visiting facilities regarding category C are divided into one category of the middle class of young families with similar tastes.
In addition, facilities belonging to category A have almost no visit history, and prefer to visit specific fast food restaurants such as beef bowl chain stores belonging to category B, and specific brand specialty stores and brand outlets belonging to category C. It is presumed that mobile users who prefer to visit facilities and the like are classified into one category of single small rich people who have similar tastes of visiting facilities regarding categories A to C.

Then, for example, a cram school chain store whose price is lower than the average designates a cluster of the above-mentioned specific "middle class of young families" and refers to the facility to mobile users belonging to the cluster. By distributing facility information, it becomes possible to carry out targeting advertisements with higher accuracy.
Although the usefulness of the present invention has been described above with some examples, the present invention is not limited to these exemplified categories. In all categories, classification by clustering processing based on the visited facility list does not use sensitive data such as those obtained from customers by questionnaire, so the person in charge of the facility who wants to distribute facility information can feel at ease. , Has the effect of being able to be used.

The input unit 36 is composed of an input device (not shown) such as a touch panel provided on the display surface of the keyboard and the display unit 35. By outputting an operation input from the input unit 36, for example, a signal based on a key press by an operator or a touch of a touch panel to the control unit 31, an operation such as an input operation by an operator or a selection operation can be realized.

Next, the details of the control unit 31 will be described. The control unit 31 is composed of 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 32, reads information from the RAM, ROM, and the storage unit 32 at the time of execution, writes information to the RAM and the storage unit 32, and writes the 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. Then, in this way, the processing in the present embodiment is realized by the cooperation of the hardware and the software (program).
In this way, the control unit 31 causes the information analysis device 30 to function as a predetermined means (hereinafter, collectively referred to as “information analysis control unit”) by executing each program.
Further, the control unit 31 causes the information analysis device 30 to execute a predetermined step (hereinafter, collectively referred to as “information analysis control step”) by executing each program.
Hereinafter, the functions of the control unit 31 will be described from the viewpoint of the information analysis control unit. The description based on the viewpoint of the information analysis control step (method) can be explained by replacing "part" with "step", and thus is 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.

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

[About location information database 322]
As shown in FIG. 6, the location information database 322 includes "location information" and "identification information" received from the in-vehicle navigation device 10 and the mobile terminal 20 as described above.
Specifically, the position information, time information, etc. that are periodically transmitted from the time when the vehicle 60 is turned on to the time when the vehicle 60 is turned off (that is, from departure to arrival) are managed for each identification information of the vehicle 60. It is stored in the movement history record (not shown). By doing so, the movement history record stores the information of the current position sequentially received from the vehicle 60. The reception may be received once every few seconds, or it may be saved in chronological order on the vehicle 60 side so that it can be received collectively at a certain time or when the application is started on the vehicle 60 side. You may. The movement history record may be stored as a temporary record in the location information database 322 as a record for which the visiting facility has not been determined.
Regarding the departure facility ID corresponding to the departure position and the visiting facility ID corresponding to the arrival position, the departure position and the arrival position are converted into map information based on the map information 321 of the storage unit 32, the facility position information, and the like. The departure facility ID and the arrival facility ID can be specified by comparing with the included facility information.
The movement history record is stored as a record in the location information database including the visiting facility information by determining the visiting facility which is the arrival position when the vehicle is ignited off.
The location information database 322 is a "departure position" and a "visit facility" specified 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 mentioned above, the "visit facility" includes undecided data when the vehicle 60 is in motion.
Then, the location information database creation unit 311 constructs and updates the location information database 322 by storing the information corresponding to each attribute in the field.

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

If the position information does not include information indicating the parking position, for example, the position corresponding to the last received position information from the start to the end of the transmission of the position information or a constant position. It is also possible to identify the visiting facility by considering the position that does not change with time as the 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 location information does not include the information indicating the parking position, for example, the facility set as the destination in the route guidance can be specified as the visiting facility.

The degree of "matching" between the parking position and the facility position described above may be arbitrarily determined. For example, when the vehicle-mounted navigation device 10 or the mobile terminal 20 can measure the position information with high accuracy, the range for determining the match may be narrowed. On the other hand, when the vehicle-mounted navigation device 10 or the mobile terminal 20 cannot measure the position information with such high accuracy, the range for determining the match may be widened. That is, even if the positions are slightly misaligned, it may be determined as a match.

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

Further, the "departure position" in the location information database 322 is the departure position in the movement route when moving to the visiting facility.
The location information database creation unit 311 identifies the departure position 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. 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 the transmission of the position information is the departure position. It can also be regarded as.
The location information database creation unit 311 specifies whether or not the departure position is a facility (and a parking lot associated with the facility) included in the map information 321 based on the departure position specified in this way. be able to.

Further, the "location information" in the location information database 322 is all the location information that changes discretely with time from the departure position to the parking position in the movement route when the visiting facility is visited. In addition, in the "location information" in the location information database 322, the location information from the first departure position to the visiting facility shall be concatenated and stored. The location information database creation unit 311 stores all the location information received during the period from the start to the end of the transmission of the location information in the field.

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

<Mobile visit determination unit 312>
Next, the mobile visit determination unit 312 will be described.
The moving object visit determination unit 312 can create and store the moving object visit data of the vehicle 60 by referring to the past movement history of the position information of the position information database 322 based on the identification information of the vehicle 60. 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, 12 months, etc., based on the location information database 322. Extract all facilities. Then, the mobile visit data for the visits of all the facilities visited within the predetermined period is created and stored in the storage unit 32. The predetermined period is not limited to 3 months, 6 months, 12 months, or the like. It can be set arbitrarily based on the characteristics of the facilities belonging to the category.
The mobile visit determination unit 312 may create mobile visit data as facility information by adding detailed data such as the date and time of the visit and the staying time to the category to which the facility belongs and the name of the facility.

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

<Clustering processing unit 314>
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, and moves based on the accumulated visiting facility list. Performs a clustering process that divides the body users into clusters. By doing so, the same attribute label can be attached to the mobile users belonging to the same cluster.
It should be noted that clustering is a so-called "data classification method without a teacher", and is a method for automatically classifying data without an external standard. In this embodiment, the clustering process by category will be briefly described by taking clustering by the K-means method, which is a known non-hierarchical method, as an example. The method related to clustering is known to those skilled in the art, and a known clustering method other than the K-means method, which is 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 list of visiting facilities of each moving body (vehicle 60) according to a plurality of categories stored in the storage unit 32. Here, the total number of moving objects (vehicles 60) that have visited arbitrary facilities belonging to a plurality of categories is N.
The clustering processing unit 314 generates a feature vector by using the visit facility list for each category of each moving body i (1 ≦ i ≦ N). Therefore, the clustering processing unit 314 sets the total number of visits to the facilities belonging to the plurality of categories to the facilities belonging to the plurality of categories within the predetermined period in advance, for example, to be equal to or higher than a preset threshold value. It is preferable to prepare a list of M facilities (M is an arbitrary natural number) of facilities j (1 ≦ j ≦ M). As a result, the data of the facility with a small total number of visits of the mobile body i (1 ≦ i ≦ N) (that is, the facility with a small number of visits of the mobile body user within a predetermined period) is excluded as noise. The processing time can be shortened.
Then, the number of times the moving body i (1 ≦ i ≦ N) visits the facility j (1 ≦ j ≦ M) n (i, j) (0 ≦ n) is the characteristic of the moving body i (1 ≦ i ≦ N). A feature vector as a vector (i, j) can be generated.
The feature vector shown above is only an example, and is not limited to this. For example, when the moving body i (1 ≦ i ≦ N) has visited the facility j (1 ≦ j ≦ M), the feature amount (i, j) = 1 and the moving body i (1 ≦ i ≦ i ≦). When N) has never visited the facility j (1 ≦ j ≦ M), a feature vector may be generated in which the feature amount (i, j) = 0 of the moving body i (1 ≦ i ≦ N). .. Further, a threshold value 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, for example, equal to or greater than the threshold value. In addition, the feature vector of each moving body i (1 ≦ i ≦ N) may be generated from the visiting facility list for each category of each moving body 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 mobile body i (1 ≦ i ≦ N) based on the feature vector, and each cluster corresponding to the number of clusters (““ Set the initial value of the representative vector of (also called "unit").
After that, the clustering processing unit 314 performs each moving body i (1 ≦ i ≦ N) so that the distance (for example, the Euclidean distance) between the feature vector and the representative vector of each moving body i (1 ≦ i ≦ N) is minimized. ) Is distributed to any of multiple units.
After that, the clustering processing unit 314 calculates a new representative vector of the unit based on the feature vector of the moving body i (1 ≦ i ≦ N) distributed to each unit for each unit. Based on the new representative vector, the clustering processing unit 314 performs each moving body i (1 ≦ i ≦ N) so that the distance between the feature vector and the representative vector of each moving body i (1 ≦ i ≦ N) is minimized. The feature vector of N) is distributed to any of a plurality of units. In this case, when the units are reassigned, the clustering processing unit 314 is a new representative of the units based on the feature vector of the moving body i (1 ≦ i ≦ N) distributed to each unit. The vector is calculated, and the feature vector of each moving body i (1 ≦ i ≦ N) is distributed to any of a plurality of units based on the new representative vector in the same manner as described above. By repeating such processing, the clustering processing unit 314 can complete the clustering when the redistribution of the units is no longer performed.
The feature vectors of moving objects with similar visiting facilities in each category are assumed to be close in distance. From this, it can be expected that by the clustering process described above, moving objects having similar visiting facilities in each category will be distributed to the same cluster.

In this way, the clustering processing unit 314 collects 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 visited 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 attached to the mobile users assigned to the same cluster. As described above, the example clustering process is an example, and the present invention is not limited to this. By applying a known clustering method, the visiting facility list for each category in the plurality of categories of the vehicle 60 (moving body) is collected from the plurality of moving bodies, and the visiting facility list is divided into clusters to make the same. The same attribute label may be attached to the mobile users distributed to the cluster.
In this way, by cluster analysis of the visited facility list for each category in the plurality of categories of the mobile body, similar users of the facilities to be visited are clustered in the same cluster in each category of the user of the mobile body in the plurality of categories. Can be distributed to. By doing so, it is possible to obtain profiling data representing the attributes of the mobile users assigned to the same cluster. That is, the user's profiling data can be obtained only from the floating car data without using sensitive data such as the Internet search history and the contents of the mail.

<Facility Information Distribution Department 315>
The facility information distribution unit 315 is divided into clusters by the clustering processing unit 314, and the mobile users are similar to the visiting facilities in a plurality of categories, so that the distribution information targets the categorized users. Can be delivered.
More specifically, the facility information distribution unit 315 collects the visited facility lists for each category in a plurality of categories, and the mobile user belonging to each cluster calculated by accumulating the visit facility preferences in the plurality of categories. Since it is presumed that the users are similar to each other, for example, when an arbitrary cluster is specified via the input unit 36, the distribution information can be distributed to the mobile users belonging to the cluster. ..
Referring to the above-mentioned examples (Category A, Category B, Category C), for example, a cram school chain store whose price is lower than the average of a young family having similar tastes of visiting facilities from Category A to Category C mentioned above. By designating a middle-tier cluster and distributing facility information about the cram school chain store to mobile users who belong to the cluster, it is possible to perform more accurate targeting advertisements.
By doing so, it is possible to provide the targeting advertisement according to the preference (characteristic) of the mobile user in a plurality of categories, so that the mobile user who receives the distribution information of the facility feels annoyed. Is reduced.
In the above example, the public relations person (operator) exemplifies an embodiment in which a predetermined cluster is designated via the input unit 36, but the present invention is not limited to this. For example, although not shown, a predetermined cluster may be designated via a terminal device communicably connected to the information analysis device 30.
Further, when designating a predetermined cluster, for example, the display unit 35 may display a cluster attribute list (or a visited facility list) or the like so that the cluster can be selected from the attribute list.

The embodiments of each functional unit of the information analysis system 1 of the present invention have been described above based on the configurations of the vehicle-mounted navigation device 10, the mobile terminal 20, and the information analysis device 30 mounted on the vehicle 60. It should be noted that the embodiment of each functional unit included in the information analyzer 30 of the present invention is distributed even in one computer, in one place or in several places, and distributed in a large number of computers interconnected by a communication network. Can be deployed to run. It can also be configured using multiple virtual computers on the cloud.

<Operation of this embodiment>
Next, the operation of the present embodiment will be described with reference to the flowcharts of FIGS. 7 and 8. Here, FIG. 7 is a flowchart showing an operation at the time of collecting location information and updating the location information database. Further, FIG. 8 is a flowchart showing an operation at the time of analysis of overlapping visiting facilities for a moving body user (user of vehicle 60).

First, the operation at the time of collecting the position information of the vehicle-mounted navigation device 10 and creating / updating the position information database 322 will be described with reference to FIG. 7.
It is determined whether or not the position information transmitting unit 112 starts transmitting the position information (step S11). Here, as described above, transmission is started when the ignition switch of the vehicle 60a is turned on. If the ignition switch remains off (No in step S11), transmission by the position information transmitting unit 112 is not started. On the other hand, when the ignition switch is turned on (Yes in step S11), the process proceeds to step S12.

In step S12, the sensor unit 14 acquires position information by positioning the position of the vehicle-mounted navigation device 10 (step S12).

The position information transmission unit 112 acquires position information from the sensor unit 14, and transmits the acquired position information to the information analyzer 30 in real time or burst transmission at a predetermined cycle (step S13).

In step S14, the location information database creation unit 311 of the information analysis device 30 creates and updates the movement history record in the location information database 322 based on the location information transmitted in step S13.

Next, it is determined whether or not the position information transmission unit 112 ends the transmission of the position information (step S15). As described above, the transmission ends when the ignition switch of the vehicle 60a is turned off. When the ignition switch of the vehicle 60a remains on (No in step S15), positioning in step S12, transmission in step S13, and creation / update of the movement history record in the 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 S16, the location information database creation unit 311 of the information analysis device 30 updates the location information database 322 (visit facility) by determining the visit facility of the movement history record when the transmission of the location information is completed.
By the operation described above, the collection of location information and the creation and update of the location information database are realized.

Next, the operation at the time of collecting the location information of the mobile terminal 20 and updating the location information database will be described. Regarding the mobile 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 reference set to Yes in step S11 is "a vehicle such as an ignition switch". Replaced with "when the start switch of 60b is turned on and the vehicle 60b and the mobile terminal 20 are paired", and the criterion of Yes in step S14 is "the start switch of the vehicle 60b such as the ignition switch is turned off and the vehicle 60b and the mobile terminal 20 are carried." It may be replaced with "when the pairing of the terminal 20 is canceled". Therefore, duplicate explanations will be omitted.

Next, with reference to the flowchart of FIG. 8, the operation of the information analysis device 30 at the time of cluster analysis (clustering process) regarding the mobile user (user of the vehicle 60) will be described.

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

In step S22, the visiting facility list creation unit 313 creates and stores a list of visiting facilities 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 collects the visited facility list for each category and performs cluster analysis.

In step S24, the clustering processing unit 314 collects the visiting facility lists for each category and divides them into clusters, thereby assigning the same attribute labels to the mobile users who are distributed to the same cluster.

As described above, by cluster analysis of the visiting facility list for each category in the plurality of categories of each moving object (vehicle 60), similar users of the facilities to be visited in each category of the user of the moving object in the plurality of categories are analyzed. Can be distributed to the same cluster. The attributes of each cluster obtained by the clustering process in this way can be given to the mobile users assigned to the cluster.

According to the present embodiment described above, by performing a cluster analysis on a facility visited by a plurality of mobile bodies, the preference of the mobile body user can be easily grasped as a typified mass, whereby the mobile body can be easily grasped. It is possible to provide targeting advertisements according to the user's preference (characteristics).
In this embodiment, the clustering process based on the visited facility list for each category in the plurality of categories of the vehicle 60 (moving body) is illustrated, but it can also be applied to the clustering process based on the visited facility list in one category.
