(Embodiment)
1 to 10 are diagrams for explaining the embodiment. Hereinafter, the present embodiment will be described along the following flow with reference to these drawings. First, “1” indicates an outline of the whole embodiment. Then, “2” describes the server configuration, and “3” describes the processing flow. Finally, the effects and the like according to the present embodiment will be described after “4”.

(1 Overview)
(1.1 System overview)
FIG. 1 is a diagram illustrating a schematic configuration of a communication system 1 including a server 100 that is an information processing apparatus. As shown in FIG. 1, the communication system 1 includes a server 100, a server 200, and one or more clients 300. The server 100, the server 200, and the client 300 are each connected to the public network N. The public network N may be any type of network as long as the server 100, the server 200, and the client 300 can communicate with each other. For example, in addition to the Internet, a mobile phone network may be considered.

  Here, the communication system 1 is a system in which the client 300 can receive an information providing service from each of the server 100 and the server 200. As a specific example of the information providing service, for example, in response to a request from the client 300, a map indicating the location of the facility designated by the request is provided, or facility information (information such as facility name, telephone number, address, etc.) is provided. And other services.

  The client 300 is a portable information processing apparatus that can be carried by a user (not shown). Specific examples of the client 300 include a portable terminal (whether it is a so-called smartphone or a feature phone), a notebook PC (Personal Computer), a PDA (Personal Data Assistance), etc. And an input unit.

  The server 100 and the server 200 include facility databases (DB) 110 and 210 and service providing units 120 and 220, respectively. The server 100 and the server 200 perform the above-described various information providing services to the client 300 by the service providing units 120 and 220. Hereinafter, the information provided by the service providing units 120 and 220 to the client 300 will be described as facility information. In the following explanation, “facility” means not only buildings (buildings) such as buildings, but also stores, offices, etc. that move into the building, outdoor facilities such as parks, and any outdoor point. (For example, “XX Square” in the park, “XX Statue” used for meeting, a bus stop, etc.) etc.

  Here, the service providing units 120 and 220 refer to the facility DB 110 and the facility DB 210, respectively, when providing various services. In particular, when the service providing unit 120 of the server 100 provides a service, the facility information is acquired from both the facility DB 110 that the server 100 has and the facility DB 210 that the server 200 has, and the information is collated. Information that summarizes these is provided to the client 300. That is, the data in the facility DBs 110 and 210 must be collated (integrated).

(1.2 Specific examples of facility DB)
Hereinafter, specific examples of the facility DBs 110 and 210 in the present embodiment will be described.
FIG. 2 is a diagram illustrating a specific example of the facility DB 110 included in the server 100. In the example of FIG. 2, the facility information of each facility that the facility DB 110 has includes a facility ID that is uniquely assigned to each facility, a name, an address, a telephone number, and a business type of each facility, and location information ( Latitude and longitude).

  On the other hand, FIG. 3 is a diagram illustrating a specific example of the facility DB 210 included in the server 200. In the example of FIG. 3, the facility information of each facility in the facility DB 210 includes a facility ID that is uniquely assigned to each facility, a name, an address, a telephone number, and a business type of each facility, and location information ( In addition to (latitude and longitude), word-of-mouth information and evaluation information are included.

  Here, in this embodiment, the facility DB 210 included in the server 200 is created based on the facility DB 110 included in the server 100. However, for reasons such as the administrator of the server 100 being different from the administrator of the server 200, the facility IDs that are uniquely assigned to the facilities differ between the facility DB 110 and the facility DB 210 (the server 200 Assign a new facility ID).

  Information such as word-of-mouth and evaluation is added by the server 200 based on information received (input) from the client 300 by the service providing unit 220, for example. Since the server 100 needs to acquire this facility information from the server 200 in order to use the additional information (information such as reviews and evaluations), the facility information in the facility DB 110 and the facility information in the facility DB 210 are used. It is necessary to make a one-to-one correspondence.

  However, as described above, the facility DB 110 and the facility DB 210 have different facility IDs for uniquely identifying facility information (facility) on the respective databases, and the administrator of the server 100 further determines the facility of the server 200. Since the ID cannot be known, the server 100 cannot collate the facility information in the facility DB 110 with the facility information in the facility DB 210 depending on the facility ID.

  It is also possible to associate the facility information in the facility DB 110 and the facility information in the facility DB 210 with information such as the name, address, and telephone number, but it is difficult to ensure complete uniqueness for this method as well. .

  First, the name is not guaranteed to be unique. When there are a plurality of facilities having the same name on the database, the facility information cannot be associated one-to-one between the facility DB 110 and the facility DB 210. As for the address, each facility (store, etc.) residing in the same building (commercial facility, hotel, etc.) often has the same address. Cannot be associated on a one-to-one basis. Regarding telephone numbers, there are cases where telephone number data does not exist (for example, in the case of outdoor facilities), and there are cases where a single telephone number is assigned to a plurality of facilities (for example, various stores in hotels). Therefore, the facility information cannot be associated one-on-one.

  Therefore, in the facility DB 110 of this embodiment (and the facility DB 210 created by reflecting the facility DB 110), the facility information in the facility DB 110 and the facility information in the facility DB 210 are 1 by assigning the position information uniquely for each facility. It is possible to associate with one-to-one.

(1.3 Location information allocation method)
An overview of a method for uniquely assigning location information to a facility will be described with reference to FIG. In FIG. 4, the “representative point” is the position of the position information that the facility information of a plurality of facilities overlaps in the original facility DB 110 (the facility DB 110 before allocation of unique position information). For example, the position of the position information assigned uniformly to all the facilities (stores, etc.) in the building 40 can be considered as an example of “representative points” in FIG.
In FIG. 4, the broken lines correspond to latitude and longitude. Here, it is assumed that the minimum unit of position information (latitude and longitude) in the facility DB 110 is 1 millisecond.

  One millisecond corresponds to about 30 millimeters in the north-south direction (latitude direction), and about 25 millimeters at 35 degrees north latitude in the east-west direction (longitude direction). Therefore, in the display on the map and the like, even if moved for several milliseconds to several tens of milliseconds, there is no significant change in position, and no major problem arises from the viewpoint of using facility information (and position information). Can be considered a thing. Therefore, in this embodiment, for each piece of facility information having overlapping position information (representative points), as shown in FIG. 4, the position information is changed so as to indicate positions near the representative points. To ensure uniqueness.

  More specifically, for each facility information having position information of the position of the representative point indicated by “x” in FIG. 4, the numerical values are changed as follows so that the position information does not overlap (is unique). Let In the example of FIG. 4, the position information (latitude, longitude) is set to (+1 msec, +0 msec) for the first facility information, and (+1 msec, +1 msec) for the second facility information. The third facility information is (+0 msec, +1 msec), the fourth facility information is (−1 msec, +1 msec), and the fifth facility information is (−1 msec, +0 msec). Repeat until there is no duplication of position information. Thereby, the position (representative point) corresponding to the position information is hardly changed, and the position information can be made unique.

  In this way, by making all the location information included in each facility information included in the facility DB 110 unique, it is ensured that the location information is a key between the facility DB 210 and the facility DB 110 created based on the facility DB 110. The facility information can be verified on a one-to-one basis.

In the present embodiment, both values of latitude and longitude are changed when the position information is made unique. By using both values, it becomes possible to concentrate the position of the changed position information in the vicinity of the original representative point, compared to the case where only one of the latitude and longitude values is changed to be unique. .
However, the present invention is not limited to this, and for example, only one value of latitude and longitude may be changed to make the position information unique.

  In the present embodiment, the position information is made unique by changing the latitude and longitude in units of 1 millisecond. However, the present invention is not limited to this. For example, it is a little larger, for example, in units of 5 milliseconds or 10 milliseconds. It may be changed in units. However, if the change is made in a unit that is too large, the influence on the display on the map and the like will increase, so the change unit is preferably set to 100 milliseconds or less.

(2 System overview)
Hereinafter, the functional configuration of the server 100 according to the present embodiment will be described with reference to FIG. FIG. 5 is a functional block diagram showing a functional configuration of the server 100 according to the present embodiment.

  As described above, the server 100 can transmit to the client 300 information that combines the facility information of the facility DB 110 that the server 100 itself has and the facility information of the facility DB 210 that the server 200 has.

  The server 100 includes a facility DB 110, a building boundary information DB 115, a service providing unit 120, an input unit 130, a location information changing unit 140, a first information acquiring unit 150, a second information acquiring unit 160, and a communication interface 170.

  The facility DB 110 manages facility information of each facility as described in “1.2” above with reference to the specific example of FIG. The input unit 130 is a module for inputting facility information (including a part thereof) stored in the facility DB 110. Here, various input methods of facility information can be considered, for example, reading from various storage media such as a DVD (Digital Versatile Disk), or an operator inputting from various input devices such as a keyboard and a mouse, It may be possible to receive facility information from another information processing apparatus via the communication interface 170.

  The building boundary information DB 115 is a database related to coordinate information indicating a building area. As will be described later, the position information changing unit 140 determines the value of the changed position information according to whether the position indicated by the position information is inside the building or outside the building.

  The position information changing unit 140 updates the position information included in the facility information input from the input unit 130 and stored in the facility DB 110 so that each facility information can be uniquely identified. The concept of this method has been described with reference to FIG. 4 in “1.3” above, but in addition, details will be described with reference to FIG. 6 and the like in “3.1” to be described later.

  The first information acquisition unit 150 acquires facility information from the facility DB 110 according to the service provided by the service providing unit 120 to the client 300. The facility information to be acquired may be one or plural. The first information acquisition unit 150 outputs the facility information read from the facility DB 110 to the service providing unit 120 and obtains position information (latitude and longitude) as a key for acquiring the facility information of the corresponding facility from the server 200. 2 Output to the information acquisition unit 160.

  The second information acquisition unit 160 acquires facility information stored in the facility DB 210 from the server 200 via the communication interface 170. As a method for providing facility information by the service providing unit 220 of the server 200, a method using API (Application Program Interface) or the like can be considered. In this case, the second information acquisition unit 160 can receive facility information that matches the position information by giving the API position information as a key.

  The service providing unit 120 transmits various facility information to the client 300 in response to a request from the client 300. At this time, in addition to the facility information acquired by the first information acquisition unit 150 from the facility DB 110, the service providing unit 120 also includes information included in the facility information acquired by the second information acquisition unit 160 from the server 200. 300 can be provided. At this time, the facility information needs to be linked. In the present embodiment, as described above, the location information uniquely assigned to each facility information can be used to associate both facility information. ing.

  The communication interface 170 is an interface that can communicate with the public network N using, for example, TCP / IP (Transmission Control Protocol / Internet Protocol). Service provision to the client 300 by the service providing unit 120 and acquisition of facility information from the server 200 by the second information acquisition unit 160 are performed via the communication interface 170.

(3 Process flow)
Hereinafter, a processing flow in the server 100 will be described with reference to FIGS. 6 to 10. Each processing step to be described later can be executed in any order or in parallel as long as there is no contradiction in processing contents, and other steps can be added between the processing steps. good. Further, a step described as a single step for convenience can be executed by being divided into a plurality of steps, and a step described as being divided into a plurality of steps for convenience can be executed as one step.

(3.1 Location information change process)
First, a process related to the location information change of the server 100 will be described with reference to FIG. FIG. 6 is a flowchart showing a flow of processing of the server 100 related to position information change.

  The location information changing unit 140 reads the facility information stored in the facility DB 110, and determines whether or not there is a plurality of facility information having the same latitude and longitude values (values indicating the original representative points) in the location information (S601). ). If there is no facility information including location information having the same value (No in S601), the location information is already considered to be unique with respect to all the facility information, and the processing is terminated.

  If there are a plurality of pieces of facility information having the same position information (Yes in S601), the position information changing unit 140 checks whether the position of the position information (corresponding to the representative point) is within the building 40 ( S603). At this time, the position information changing unit 140 can determine whether it is inside or outside the boundary of the building 40 (whether it is within the area (region) of the building 40) by referring to the building boundary information DB 115. .

  If the representative point of the facility information to be processed is in the building 40 (Yes in S603), the position information changing unit 140 determines whether there are representative points of other facility information at different positions in the same building 40. Is discriminated (S605). If the representative point to be processed is the only representative point in the building 40 before the position information is changed by the position information changing unit 140 (No in S605), the position information changing unit 140 is duplicated. It is determined whether or not the number of facility information items that can be secured can be secured in the building 40 (S609). Here, “point” means a latitude line and a longitude line in units of 1 millisecond (in the present embodiment, described as 1 millisecond, but other units such as 5 millimeters and 10 millimeters are also conceivable). Point to the point where.

  If all the facility information points can be secured in the building 40 (Yes in S609), the representative points that need to be placed around the original representative points in the building 40 (original representatives). The position of the facility information where the position information indicates the point) is sequentially arranged (changes the position information) (S611). This process is similar to that described above with reference to FIG.

  If all points necessary for the rearrangement of the representative points cannot be secured in the building 40 in S609 (No in S609), first, the representatives of the facilities are placed on the points in the building near the representative points. The points are arranged as much as possible (position information included in the facility information is changed) (S613), and then the representative point of the remaining facility is arranged at a point outside the building 40 near the representative point (the facility information of the facility) The position information included in the data is changed) (S615).

  An overview of the processing of S613 and S615 by the position information changing unit 140 is shown in FIG. In the example of FIG. 7, since only a total of 12 points (including the original representative points) can be secured in the building 40, the 13th and subsequent points (points indicated by “12” in the figure) are outside the building 40. Therefore, they are arranged in order so as to be as close to the original representative point as possible. In this way, by setting the representative point of the facility (location information of the facility information) in the building 40 as much as possible, the occurrence of various inconveniences such as the user misinterpreting the location of the facility after the change of the location information is minimized. It becomes possible to suppress.

  In addition, in S605, in addition to the selected representative point, if there is a representative point of other facility information at a different position in the same building 40 (Yes in S605), the position information changing unit 140 is the same as in S609. Then, it is determined whether or not the number of pieces of facility information requiring rearrangement can be secured in the building 40 (S617).

  When the number of necessary facility information in the building 40 can be secured (Yes in S617), the representative points to be arranged around the respective original representative points in the same building 40 are ratios of the numbers. It arranges according to. An overview of the process of S619 will be described with reference to FIG. FIG. 8 shows that there are two representative points (representative points A and B) of the facility information before the change in one building 40, the number of facility information having position information indicating the representative point A, and the representative point B The number of pieces of facility information having position information indicating 1 is 2 (for example, 10 pieces of facility information have position information showing representative points A, and 20 pieces of facility information show representative points B) It is a figure which shows the change method of position information in the case of having position information.

  In the example of FIG. 8, the position information indicating the representative point B every time one representative point of the facility having the position information indicating the representative point A is arranged around the representative point A (position information is changed). Two representative points of the facility having the are arranged around the representative point B. By mounting in this way, since the representative point of the facility after the change comes around the original representative point as much as possible, it is possible to avoid a large change in the position information.

  In S617, when the number of necessary facility information points cannot be secured in the building 40 (No in S617), the position information changing unit 140 first places the information around the original representative points in the building 40. The representative points that should be arranged are arranged according to the number (S621). This process is performed according to S619. Then, the representative points that could not be arranged in the building 40 are arranged outside the building 40 as much as possible in the vicinity of the original representative points (S623).

  In S603, when the position information (corresponding to the representative point) of the facility information to be processed is outside the building 40 (No in S603), the position information changing unit 140 is not sufficiently in the building 40 nearby. It is determined whether or not there are a number of points (S625). If there are a sufficient number of points (Yes in S625), the position information changing unit 140 re-represents the representative point of the facility information whose position has overlapped outside the building 40 and in the vicinity of the original representative point. Arrange (change position information) (S627).

  The process of S627 will be described with reference to FIG. It is a figure which shows the specific example in the case of newly arrange | positioning a representative point (facility position) near the original representative point which exists outside the buildings 40A and 40B (that is, outdoors). In the example of FIG. 9, when buildings 40A and 40B exist in the vicinity of the original representative point, but sufficient points can be secured on the outside (outdoors), the representative point of the facility whose position is duplicated is An example in the case of rearranging around the representative point (changing the value of position information) is shown.

  In S625, when a sufficient number of points that are not in the building 40 cannot be secured in the vicinity of the original representative points (No in S625), the position information changing unit 140 first sets the number of points outside the building 40 as much as possible. The representative points are arranged (position information is changed so as to indicate a position outside the building 40 near the original representative points), and the remaining information is arranged in the building 40 (position information is changed).

  By doing so, it is possible to set the position information uniquely without changing the position from the original representative point as much as possible and without changing the position attributes such as inside and outside the building 40 as much as possible.

(3.2 Processing of facility information provision)
Hereinafter, the flow of processing related to the facility information provision of the server 100 will be described with reference to FIG. FIG. 10 is a flowchart showing a processing flow of the server 100 for providing location information.

  This process is performed when, for example, the server 100 receives a facility information acquisition request from the client 300, or when the server 100 actively distributes the facility information to the client 300 (without request from the client 300). Done.

  First, the first information acquisition unit 150 acquires facility information from the facility DB 110 based on a request from the service providing unit 120 (S1001). Then, the first information acquisition unit 150 outputs position information (latitude and longitude) included in the facility information, and the second information acquisition unit 160 requests the server 200 to acquire facility information using the position information as a key. Is transmitted (S1003).

  When the second information acquisition unit 160 acquires the facility information from the server 200, the service providing unit 120 acquires the facility information of the facility DB acquired by the first information acquisition unit 150, and the second information acquisition unit 160 acquires from the server 200. Screen information (for example, HTML (described in HyperText Markup Language)) combined with the facility information in the facility DB 210 is generated and transmitted to the client 300 via the communication interface 170 (S1005).

(4 Effects of this embodiment)
As described above, the server 100 according to the present embodiment is capable of associating the facility information, which is information related to the facility, on a one-to-one basis by uniquely setting the position information. In addition, when making the position information unique, the position information is changed in order from the lowest position information value (millisecond in this embodiment), so the position change is kept to a minimum. , Minimizing the influence on the position display on the map.

  Moreover, by using the key that associates the facility information instead of the facility ID as the position information, even if the value of the facility ID is changed or the position information cannot be known, the two facilities DB 110 and 210 It is possible to provide information combined with facility information.
