By sending to the mobile phone by text etc., it is possible to receive a guidance service according to time and place.

Japanese Patent Laid-Open No. 2000-215211

  However, since the guidance script created in Patent Document 1 guides a general spot, information different from the user's intention may be provided. For example, sending general store information to a user who wants outdoor shop information is not useful information and cannot satisfy the user's satisfaction.

  An object of the present invention is to provide an information distribution device, an information distribution system, and an information distribution method capable of distributing spot information that satisfies the user's satisfaction.

  An information distribution apparatus according to the present invention is an information distribution apparatus that is connected to a plurality of user terminals via a network and distributes spot information to the user terminals. Each spot visited by each user from the plurality of user terminals. Log collection means for collecting the spot visited by each user within a predetermined period as log data, and calculating a co-occurrence spot for each spot included in the log data, and calculating the spot and the co-occurrence Co-occurrence spot calculation means for associating and storing the spot in the storage means, the current position of the user is received from the user terminal, and the co-occurrence spot for the spot closest to the current position of the user is extracted from the storage means. Co-occurrence spot extracting means and the extracted co-occurrence spot are distributed to the user terminal as the spot information. Characterized by comprising a spot information distribution means, the for.

In the present invention, spots actually visited by a user within a predetermined period from a plurality of user terminals are collected as log data, and a co-occurrence spot for each spot is calculated based on the log data. Here, the co-occurrence spot will be described. When a user who visits the spot A has a high probability of visiting the spot B, the spot B is set as a co-occurrence spot of the spot A. Further, the current position of the user terminal is received by a request or setting from the user terminal, the co-occurrence spot for the spot closest to the current position is extracted from the storage means, and the co-occurrence spot is spot information for the user terminal Send as.
According to this, since the information delivery apparatus collects the spot that the user actually visited as log data, it is possible to obtain an appropriate co-occurrence spot based on the actual data. In addition, since the user who is presented with the co-occurrence spot can make a next schedule based on information about what kind of spot other people are visiting, it is possible to distribute information useful to the user. . In particular, because people who have the same hobbies and preferences are likely to visit the same spot, it is possible to deliver useful information for the user by presenting the co-occurrence spot obtained based on actual data to the user. it can. That is, user satisfaction can be improved.

  In the information distribution apparatus according to the present invention, the co-occurrence spot calculation means includes, for the spot and the arbitrary spot, a ratio of the number of persons who are at both the spot and the arbitrary spot with respect to the number of persons at the spot, and the arbitrary spot. The co-occurrence degree obtained by multiplying the ratio of the number of people who were in both the spot and the arbitrary spot with respect to the number of people who were in the spot, and if the co-occurrence degree is equal to or greater than a predetermined threshold, A co-occurrence spot with respect to the spot is preferable.

  In the present invention, the co-occurrence between each spot and another arbitrary spot is determined using an index called a co-occurrence degree. The higher the co-occurrence degree is, the higher the co-occurrence is, and a threshold is set to determine whether or not it is a co-occurrence spot. According to this, since the index of the co-occurrence degree is used, the co-occurrence spot can be appropriately obtained. Therefore, the information distribution apparatus can provide information that the user satisfies with the co-occurrence spots that are appropriately obtained.

  In the information distribution apparatus of the present invention, the co-occurrence spot extraction unit extracts a co-occurrence spot for the spot from the storage unit when the current position of the user is a spot, and the current position of the user is determined from the spot. In the case of being away, it is preferable to identify the spot closest to the current position of the user and extract the co-occurrence spot for the spot from the storage means.

  The current position acquired from the user terminal may be on the road and is not necessarily at the spot. Therefore, if the current position is in the spot, the spot can be specified, but if the current position is not in the spot, the spot at the closest position is specified. Thereby, since the data received from the user terminal can be used without waste and a large number of log data can be collected, a more appropriate co-occurrence spot based on the actual data can be obtained.

The flowchart which shows operation | movement of the said information delivery apparatus. The flowchart which shows operation | movement of the said information delivery apparatus.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the information distribution system 1 has a configuration in which an information distribution apparatus 10 and a user terminal 20 are connected via the Internet 2.

The user terminal 20 is registered as a user in the information distribution apparatus 10 in advance, and each user terminal 20 is given a user ID for identifying the user. Among the user terminals 20 registered as a user, the user terminal 20 that permits transmission of position information to the information distribution apparatus 10 transmits the current position to the information distribution apparatus 10. The information distribution device 10 stores the received current position of the user terminal 20 as log data, and obtains a co-occurrence spot for each spot based on the accumulated log data.
The information distribution apparatus 10 acquires the current position of the user terminal 20 and transmits a spot corresponding to the current position or a co-occurrence spot for the closest spot to the user terminal 20.

Hereinafter, each configuration will be described in detail.
The Internet 2 is the Internet based on a general-purpose protocol such as TCP / IP, but is not limited to this. For example, any configuration that transmits and receives data, such as a network such as a communication network in which a plurality of base stations capable of transmitting and receiving information via a wireless medium configure a network, can be used.

  The information distribution apparatus 10 includes a storage unit such as a RAM (Random Access Memory) or a ROM (Read Only Memory) and a control unit such as a CPU (Central Processing Unit) as a hardware configuration. The RAM has a temporary area where data and the like can be temporarily stored, and the ROM stores an OS (Operating System: basic software), programs for controlling various servers, various applications, various data, and the like. The CPU reads programs stored in these storage means and performs various processes according to the programs.

As shown in FIG. 1, a log database 101, a co-occurrence spot database 102, a user database 103, and a spot database 104 are stored in the storage unit of the information distribution apparatus 10.
For example, as shown in Table 1 below, the log database 101 includes a user ID that identifies the user terminal 20, a spot ID that identifies a spot visited by the user terminal 20, and a time associated therewith. It has a table structure stored as a record. Here, the user ID is uniquely identifiable and stored in the user database when user registration is performed to use the information distribution apparatus 10. The spot ID is assigned so that the spot can be uniquely identified, and is stored in advance in the spot database. The items are not limited to those listed here, and other items may be added as appropriate as long as they can be used as log data.

  In the co-occurrence spot database 102, for example, as shown in Table 2 below, a spot ID for identifying a spot and two spot IDs that co-occur on this spot are associated and stored as one record. It has a table structure. The number of co-occurrence spots stored is not particularly limited, and may be one or three or more spots may be stored.

The user database 103 stores a user ID for identifying a user, information such as user attributes, and whether or not position information can be transmitted to the information distribution apparatus 10 in association with each other.
The spot database 104 stores a spot ID for identifying a spot, a spot name, coordinates of latitude and longitude indicating the spot position, and information such as traffic guidance in association with each other.

Moreover, the information delivery apparatus 10 is provided with the setting means 11 which sets a co-occurrence spot, and the delivery means 12 which delivers spot information as a function structure of a control means.
The setting means 11 stores the spot visited by each user received from the plurality of user terminals 20 as log data, and sets a co-occurrence spot for each spot based on this log data. The setting unit 11 includes a first position information receiving unit 111, a log creating unit 112, and a co-occurrence spot calculating unit 113. Here, the first location information receiving unit 111 and the log creating unit 112 function as a log collecting unit of the present invention.

The first position information receiving unit 111 receives position information of the user terminal 20 that is periodically transmitted from the user terminal 20 that has approved transmission of the position information. Specifically, the position information calculated by receiving a GPS signal in the user terminal 20 is received. The position information includes latitude and longitude coordinates indicating the position of the user terminal 20, the time at the position, and the like. The user position information received by the first position information receiving unit 111 is used to collect log data.
The log creating unit 112 determines a spot existing at the position of the coordinate from the coordinates included in the position information received by the first position information receiving unit 111 and the coordinates of each spot stored in the spot database 104. The user ID that identifies the user who is the owner of the user terminal 20 is associated with the spot ID that identifies the spot where the user was and the time that the user was at the spot, and is stored in the log database 101 as log data.

  The co-occurrence spot calculation unit 113 calculates a co-occurrence spot for each spot based on the log data stored in the log database 101. Specifically, the number of people who visited the spot Sa within a predetermined period is P (Sa), the number of people who visited the spot Sb is P (Sb), and the number of people who visited both the spots Sa and Sb is P (Sa; Sb). And the co-occurrence degree C (Sa; Sb) of the spots Sa and Sb is obtained by the following equation (1). Here, the predetermined period can be appropriately set such as 5 hours, a half day, and a day.

  C (Sa; Sb) = P (Sa; Sb) / P (Sa) × P (Sa; Sb) / P (Sb) (1)

  If the co-occurrence degree C (Sa; Sb) is equal to or greater than an arbitrary threshold value, the co-occurrence is determined. That is, when the co-occurrence degree C (Sa; Sb) is equal to or greater than an arbitrary threshold, it can be said that the spot Sa is a co-occurrence spot of the spot Sb and the spot Sb is a co-occurrence spot of the spot Sa. The threshold value can be set arbitrarily. Then, the spot ID of the spot Sb determined to be the co-occurrence spot of the spot Sa is stored in the co-occurrence spot database 102 in association with the spot ID of the spot Sa. In this way, the co-occurrence degree for the spot Sa is calculated for all the spots, and the co-occurrence spot is obtained.

The distribution unit 12 transmits the co-occurrence spot for the current position of the user terminal 20 to the user terminal 20 as spot information. The distribution unit 12 includes a second position information reception unit 121, a co-occurrence spot extraction unit 122, and a spot information distribution unit 123. Here, the second position information receiving unit 121 and the co-occurrence spot extraction unit 122 function as a co-occurrence spot extraction unit of the present invention.
The second position information receiving unit 121 acquires user position information from the user terminal 20. Specifically, the position information calculated by receiving a GPS signal in the user terminal 20 is received. The position information includes latitude and longitude coordinates indicating the position of the user terminal 20. The user's position information received by the second position information receiving unit 121 is used to distribute optimal spot information to the user.

The co-occurrence spot extraction unit 122 identifies the spot where the user terminal 20 is located from the position information of the user terminal 20 and the coordinates of each spot stored in the spot database 104. When the coordinates where the user terminal 20 is located do not correspond to any spot, the closest spot is specified. Then, the co-occurrence spot associated with the spot ID for identifying the identified spot is extracted from the co-occurrence spot database 102.
The spot information distribution unit 123 acquires spot information associated with the spot ID that identifies the extracted co-occurrence spot from the spot database 104 and distributes the spot information to the user terminal 20. The spot information includes a spot name, a place, a business type, a traffic guide, and the like. In addition, when the coordinates where the user terminal 20 is located do not correspond to any spot, information on the closest spot specified by the co-occurrence spot extraction unit 122 is also distributed together with information on the co-occurrence spot.

  As the user terminal 20, for example, a mobile phone, a smartphone, a mobile computer, or the like can be used, and storage means such as a RAM (Random Access Memory) and a ROM (Read Only Memory), a CPU (Central Processing Unit), and the like. Control means. The user terminal 20 is configured to receive GPS signals, calculate longitude and latitude coordinates, and transmit them to the information distribution apparatus 10. A program that periodically transmits position information to the information distribution apparatus 10 is incorporated into the user terminal 20 that has approved the transmission of the position information to the information distribution apparatus 10, and this program is executed.

[Operation of Information Distribution Device 10]
Next, operation | movement of the information delivery apparatus 10 is demonstrated based on a flowchart.
In the information distribution system 1, the step of obtaining a co-occurrence spot and the step of providing spot information to the user terminal 20 operate separately.
First, the step of obtaining the co-occurrence spot will be described with reference to FIG.
In the information distribution system 1, the user terminal 20 is registered in advance in the information distribution apparatus 10 and is given a uniquely identifiable user ID. At the time of user registration, whether or not to approve the transmission of the position information to the information distribution apparatus 10 is selected, and this information is stored in the user database 103. Note that a program that periodically transmits position information to the information distribution apparatus 10 is incorporated in the user terminal 20 that has approved the transmission of the position information.

The first position information receiving unit 111 receives position information transmitted from the user terminal 20 (step S11).
Next, the log creation unit 112 identifies the corresponding spot from the spot database 104 based on the latitude and longitude coordinates included in the position information. Then, the user ID of the user terminal 20 that has transmitted the position information, the spot ID of the spot, and the time included in the position information are associated and stored in the log database 101 (step S12).

  Then, the co-occurrence spot calculation unit 113 calculates the co-occurrence degree of other spots with respect to a certain spot based on the log data stored in the log database 101 using the above equation (1), and has the co-occurrence degree. Assume that a spot that is equal to or greater than a threshold value, for example, 60% or more, is a co-occurrence spot of the spot, and associates a spot ID that identifies a spot that has been determined as a co-occurrence spot with a spot ID that identifies the spot. 102 (step S13).

  For example, a user who visits the outdoor shop A has a high probability of visiting the outdoor shop B and the outdoor shop C, but has a low probability of visiting the jewelry shop D. This probability is the co-occurrence degree described above, and the outdoor shop B and the outdoor shop C whose co-occurrence degree is equal to or greater than the threshold value are co-occurrence spots of the outdoor shop A. Therefore, the outdoor shop B and the outdoor shop C are associated with the outdoor shop A, and the respective spot IDs are stored in the co-occurrence spot database 102.

Next, the step of providing spot information to the user terminal 20 will be described with reference to FIG.
When the user wants to acquire spot information, the user accesses the information distribution apparatus 10 from the user terminal 20 and transmits a request for spot information. At this time, the location information of the user terminal 20 is also transmitted simultaneously.
The second position information receiving unit 121 receives a request from the user terminal 20 together with position information (step S21).

Next, the co-occurrence spot extraction unit 122 identifies the corresponding spot from the spot database based on the coordinates included in the received position information. If there is no such spot, the closest spot is specified. Then, the co-occurrence spot of the spot is extracted from the co-occurrence spot database 102 (step S22).
The spot information distribution unit 123 acquires information about the extracted spot from the spot database 104, and distributes the spot information to the user terminal 20 that has requested the spot information. (Step S23).

  In the example described above, when a user in the outdoor shop B accesses the information distribution apparatus 10 from the user terminal 20 to request spot information, the information distribution apparatus 10 stores the co-occurrence spot database 102 as a co-occurrence spot of the outdoor shop B. The stored spot information of outdoor shops A and C is transmitted to the user terminal 20. In addition, when there are a plurality of co-occurrence spots, the user terminal 20 may display them in order of the degree of co-occurrence.

[Operational effects of this embodiment]
According to the above embodiment, the following effects can be obtained.
The setting unit 11 collects log data based on the position information received from the user terminal 20, and obtains a co-occurrence spot for each spot based on the collected log data. As described above, since the co-occurrence spot is obtained using the information of the spot actually visited by the user, an appropriate co-occurrence spot based on the actual data can be obtained.
Further, since the distribution unit 12 distributes the co-occurrence spots appropriately set as described above as the spot information based on the current position of the user terminal 20, it can distribute the spot information suitable for the user's intention. And user satisfaction can be satisfied.

For example, if a user visiting the outdoor shop A wants to see other shops, and requests spot information from the information distribution apparatus 10, the outdoor shop that is a co-occurrence spot associated with the outdoor shop A Information on B and C is transmitted. Thus, by performing information distribution using the co-occurrence spots, information suitable for the user's hobbies and interests can be distributed, and the user's satisfaction can be improved.
On the other hand, even if there is no clear purpose of visiting an outdoor shop, it is useful for the user because it is possible to obtain information on what other people are visiting.

[Modification]
In addition, this invention is not limited to embodiment mentioned above, In the range which can achieve the objective of this invention, the deformation | transformation shown below is also included.
For example, in the above embodiment, when there is a request from the user terminal 20, the distribution unit 12 extracts the co-occurrence spot and transmits it to the user terminal 20, but the timing for distributing the spot information is not limited to this. . For example, the distribution unit 12 may periodically access the user terminal 20 to acquire the current position, and unilaterally distribute the spot information to the user terminal 20.

Further, in the above embodiment, the position information periodically transmitted from the user terminal 20 receives information and creates log data each time. For example, the coordinates of the place where the user terminal 20 visited on that day And the user terminal 20 side, and log data may be created by sending the information to the information distribution apparatus 10 at the end of the day, for example, at 24:00.
Moreover, in the said embodiment, although it was set as the structure which transmits a positional information regularly to the information delivery apparatus 10 by running the program integrated in the user terminal 20, the information delivery apparatus 10 is a position information of a positional information regularly. The configuration may be such that the location information is acquired by accessing the user terminal 20 that has approved the distribution.

  Moreover, in the said embodiment, although the setting means 11 and the delivery means 12 were comprised in one apparatus, you may comprise each means in a separate apparatus.

  The present invention can be used as an information distribution device, an information distribution system, and an information distribution method for distributing spot information to a user.
