  Hereinafter, an information acquisition system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the information acquisition system according to the embodiment. In this figure, reference numeral 1 denotes an information acquisition device. The information acquisition apparatus 1 includes an information reception processing unit 101, an information acquisition processing unit 102, a search region specifying processing unit 103, a specified attribute region extraction processing unit 104, an inclusion region search processing unit 105, a coordinate region conversion processing unit 106, A region search processing unit 107, a region position information DB (database) 108, a region inclusion relation information DB 109, a region attribute information DB 110, and a coordinate region correspondence information DB 111 are provided. The information acquisition system also includes a terminal (search instruction processing unit) 2 and a region related information collection server 3 connected to the information acquisition device 1 via a communication network.

  Here, in the information acquisition method using the information acquisition system, first, the location information of each area where information is provided by a plurality of different information providers is stored in the database, and the user's location is acquired separately. Thus, an area suitable for the target search method is searched. In the search, an area including the user position and an area included in the search range are searched, and corresponding information is acquired. In order to extract a region including the user position, it is necessary to hold the inclusion relation of the regions in the database and extract the region including the user position when given the user position. At this time, the inclusion relation between the areas is not directly described in the database, but, for example, the inclusion relation with the area represented by an address (hereinafter simply referred to as an address) is described. For example, it holds that the area is included in the address for the area in the address, and holds that the area including the address is included in the area with respect to all the addresses constituting the area. Thus, when it is acquired that the user belongs to a specific area in the address, an area including the user is acquired by acquiring an address including the area and an area associated with the address. Further, when the user's position is acquired by latitude and longitude, the same operation may be performed by converting the address into an address by using the map DB.

  For determining whether the region is included in the search range, the region having the representative point is included in the search range depending on whether a specific point (hereinafter, representative point) in the region is approximately included in the search range. Determine if it is included. That is, the region within the search range is specified by registering the latitude and longitude of the representative point of the region in the database. In addition, it is easy to search if the search range is expressed by a set of circles by determining whether or not the region is included in the search range by approximating whether the representative point of the region is included in the search range. It becomes. Then, the search range is expressed by the set of latitude and longitude of the reference point and the allowable distance from the reference point, and information corresponding to each area is obtained by taking the union of the set of areas included in each circle. Perform the acquisition process.

  Then, the information acquisition system includes an area position information DB 108 that holds the coordinates of the representative point of the area containing the information, and area inclusion relation information that holds the area inclusion relation for acquiring the area including the designated area. A DB 109 is provided. In the information acquisition system, when the information specifying the coordinates or the region and the search method are transmitted, the region is specified, the union of the specified region is calculated, and the information belonging to the region is acquired. Done.

Next, the processing flow of the information acquisition system will be described.
First, as an example, a case of searching for a URL specifying peripheral store information along a route and a case of searching for a URL for displaying a map necessary on the route with respect to a travel route predicted by the user will be shown. This example merely shows one embodiment, and does not limit the scope of the claims.

  1 shows an example of an information acquisition system in the case where there is one terminal 2 provided with a search instruction processing unit (search instruction function). However, as shown in FIGS. The form connected to an information acquisition system may be sufficient. In the present embodiment, for convenience of explanation, an explanation will be given using an example in which one terminal 2 provided with a search instruction processing unit (search instruction function) is connected to the information acquisition system.

  First, the information acquisition device 1 in the information acquisition system includes an area position information DB 108 (stores the correspondence between the area ID and the latitude / longitude information of the representative point in the area), and an area inclusion relation information DB 109 (the area ID and the address of the area). ) And a region attribute information DB 110 (stores a relationship between an area ID and information indicating the size of the area). In addition, the information registration function in each DB can be used from other servers and terminals. Then, a person who wants to send information according to the position information outside can create a state where the position information of the area used for information transmission can be registered.

  In addition to information for converting latitude / longitude and area ID (map DB <stores correspondence between latitude / longitude and address>), a boundary is defined by a set of line segments whose end points are defined by latitude / longitude for the area in the address. A coordinate region correspondence information DB having a correspondence between a region defining a region and a region ID, a correspondence between the region ID and a latitude / longitude of one point in the region, and conversion of latitude / longitude and region ID using the information included therein (latitude The information acquisition apparatus 1 includes a coordinate area conversion processing unit 106 that performs conversion into an ID of an area including longitude, or conversion of a representative point corresponding to the area ID into latitude and longitude.

 FIG. 1 shows an example in which the region position information DB 108, the region inclusion relation information DB 109, and the region attribute information DB 110 are different databases, but the functions of these databases are configured in one database. May be. Further, the area ID may be composed of an address and a number to which the area belongs, for example. For example, an area that covers a plurality of municipalities in Tokyo, such as Tokyo-A1, or an area that exists in an address, such as 5-A1, XXX City 3-4-4, Tokyo May be identified by a specific area ID.

  The area-related information collection server 3 having the area-related information collection function, for example, stores a correspondence relationship between information that specifies an area and information that belongs to the area (area ID and URL of information that belongs to the area). When the area ID is received, information belonging to the corresponding area is returned to the information acquisition apparatus 1.

  And, for example, a store manager or a server manager who collects store information is a server (for example, a Web server) for transmitting information, and when access is received, a function for transmitting information corresponding to a region Install a server with Further, the latitude / longitude of the representative point of the region is registered in the region position information DB 108, the address at which the region is located, or the address formed by the region is registered in the region inclusion relation information DB 109, and the size of the region ( For example, information specifying half of the maximum length of a line segment in the area is registered in the area attribute information DB 110. Further, the region-related information collection server 3 registers the correspondence between the URL of the web page published by the manager of the store and the server installed by the server administrator who collects the store information and the region ID. When there are a plurality of candidates for information to be transmitted in the area, for example, individual position information in the area is registered in a database installed in the own server in association with the URL of the web page. In addition, an administrator who provides information inside the station and an indoor map installs a server capable of transmitting such information in the same manner as described above, and performs similar registration.

  As a result, information in which the position information of the area corresponding to the DB in the information acquisition system is registered is acquired by the processing of each processing unit provided in the information acquisition device 1. Then, a server that receives information specifying the search method as shown in FIG. 4 and returns the search result is provided in the information system.

  In addition, when the terminal 2 or the like having an external search instruction function provides a user with a map on a route and a local map at a transit station, for example, first, a travel route is predicted from position information (for example, in the past) A server that has the function of creating information that specifies the search method from the route that is used the most frequently in the route) to receive input from the user and display the results Connect the server to the information acquisition system.

  Then, when receiving an input from the user, using the location information of the user acquired based on the search method such as the latitude and longitude acquired using the GPS receiver or the address and latitude and longitude registered in the schedule, the current location and Get destination location information. And the terminal 2 provided with the search instruction | indication function uses these acquired information and log | history, and predicts a user's moving route. Here, FIG. 5 is a diagram showing an outline of prediction of a user's movement route. When the user's purpose is to search for a store along the moving route and to acquire a local map of a station on the route, the terminal 2 having the search instruction function is shown in FIG. Store information and station premises map information in the area shown in the figure) (area with a radius of 200m centered on the current location <Point 1> and area with a radius of 100m centered on the destination <Point 3>) Therefore, information indicating the search method shown in FIG. 4 is generated and transmitted to the information acquisition device.

  Next, when the information acquisition device 1 receives information on the search method from the terminal 2, the in-area area search processing unit 107 represents the area held in the area position information DB 108 in order to acquire the surrounding information of the point 1 in FIG. Using the latitude and longitude of the point, the representative point of each region where the distance from the point 1 is 200 m or less is acquired. FIG. 7 is a diagram showing an outline of a region and representative points of the region. For example, referring to FIG. 7, the latitude and longitude of the representative points of region 1, region 2, and region 3 are located in a range of 200 m centering on point 1. Therefore, the in-region area search processing unit 107 acquires the area position information of the area 1, the area 2, and the area 3.

  For point 2, in order to search for a map in the station, the latitude and longitude of point 2 are converted into the station address using the map DB, and the address is included using the information in the area inclusion relation information DB 109, as shown in FIG. Extract regions. Here, FIG. 8 is a diagram showing an outline of extraction of a region including the point 2. Further, when the surrounding store information is searched again for the point 3 of the destination, each area whose distance from the point 2 is 100 m or less using the latitude and longitude of the representative point of the area held in the area position information DB 108 Get a representative point of. FIG. 9 is a second diagram showing an outline of a region and a representative point of the region. For example, referring to FIG. 9, the latitude and longitude of the representative points of the regions 7 and 8 are located in a range of 100 m centering on the point 2. Therefore, the in-area area search processing unit 107 acquires area position information of the areas 7 and 8.

  In this case, since information of a short distance is necessary rather than information over a wider area, for example, the size is set to 100 m or less as an attribute of the region, and thus a part of the region is not extracted. The condition for this attribute may be the type of service provided in the area. In this case, when a service type is specified in the search condition, an area having no attribute is not extracted. After performing these processes, the information acquisition processing unit 102 obtains the sum of the set of areas corresponding to the points 1 and 3 among the extracted areas, and the information acquisition processing unit 102 transmits the information to be transmitted to the area related information collection server. The information shown in the figure is transmitted to an external region related information collection server 3 having a region related information collection function.

  When the area-related information collection server 3 receives the information from the information acquisition device 1, the area-related information collection server 3 extracts URLs of information corresponding to the areas registered from the store or station, and the extracted URLs for all areas are shown in FIG. The information related to the region-related information collection server is generated and transmitted to the information acquisition device 1. When the information acquisition device 1 receives the information shown in FIG. 11 from the region-related information collection server 3, the information acquisition device 1 transfers the information to the terminal 2 having the search instruction function. Then, using the received information, the terminal 2 displays information such as that shown in FIG. 12 (a diagram showing an example of a screen displayed using the information of the search result) on the screen of the terminal 2, for example.
