Using such a database, for example, a service for searching a web page from a map can be provided.

<Functional configuration>
FIG. 2 is a diagram illustrating an example of functional blocks in the map server device according to the present embodiment. Note that the functional blocks of the map server device described below can be realized as hardware, software, or both hardware and software. Specifically, if a computer is used, a CPU, a main memory, a bus, or a secondary storage device (a hard disk, a non-volatile memory, a storage medium such as a CD or a DVD, a read drive for the medium, etc.), information Input devices used for input, printing equipment, display devices, other hardware components such as external peripheral devices, interfaces for external peripheral devices, communication interfaces, driver programs for controlling these hardware, Other examples include application programs and user interface applications.

  Then, by CPU processing according to the program developed on the main memory, the data input from the input device or other interface and held in the memory or hard disk is processed and stored, An instruction for controlling the software is generated. The present invention can be implemented not only as a map server device but also as a method. A part of the invention can be configured as software. Furthermore, a software product used for causing a computer to execute such software and a recording medium in which the product is fixed to a recording medium are naturally included in the technical scope of the present invention (the same applies throughout the present specification). Is).

  As shown in FIG. 2, the “map server device” (0200) of the present embodiment includes a “trigger reception unit” (0201), an “output unit” (0202), and a “reception unit” (0203). And an “accumulation unit” (0204) and a “map output unit” (0205).

  The “trigger reception unit” (0201) has a function of receiving a trigger for a predetermined map display request from a client, and is realized by, for example, a communication IF (interface), a CPU (central processing unit), a main memory, a trigger reception program, and the like. can do. Note that “trigger” refers to information that triggers when a predetermined map display request is made. For example, a web page in which a code for map display described by a script tag or the like is embedded is displayed on a user's client terminal device. The HTTP request that is automatically generated according to the script tag is displayed. Another example is an HTTP request generated by clicking a map display button arranged on a web page according to an embedded code.

  FIG. 3 is a diagram for explaining an example of a trigger received by the trigger receiving unit. As shown in this figure, an access code α described in a script tag such as “script˜src =“ http: // Japanmap˜ ”is embedded in the HTML document of the web page. When the user displays a web page in which the code is embedded on the client terminal, an HTTP request for accessing the address indicated by the code is generated and transmitted on the client terminal. And in the map server apparatus of a present Example, it is the condition that this trigger reception part receives the transmitted HTTP request as a trigger.

  Note that the map display code embedded in the web page may be generated as follows, for example. That is, the creator of the web page or the like accesses the map server device and inputs a map, an address of a map icon, a landmark name, or latitude / longitude information to be displayed on his / her web page according to the GUI. Then, the code for displaying the map image specified by the input information on the web page is generated by the map server device. When the code generated in this way is notified to the web page creator or the like, the creator can embed the code in the source of his web page and display the map image on the web page. It becomes possible.

  The “output unit” (0202) has a function for outputting a client program and a tag necessary for map display to the client in response to reception of a trigger. For example, a CPU, a main memory, and an output program Can be realized. The “tag necessary for map display” is a tag generated based on display map specific information (latitude / longitude information, etc.) included in the code, and is generated and output including the latitude / longitude information, for example. The In the client terminal, an HTTP request or the like for accessing a desired map image is generated using the tag.

  In addition, “the client program output in response to the reception of the trigger” refers to a program for acquiring the URL of the web page referred to when generating the trigger from the client in response to the reception of the trigger, For example, an applet type program such as Script may be used.

  Specifically, as shown in FIG. 4, the program is, for example, an applet type program, and is executed on the client terminal to acquire the URL of the web page in which the trigger is embedded. Further, this program executes an access (HTTP request) including the acquired URL to the server device. As described above, the server device according to the present embodiment easily outputs an access log including the URL of the web page referred to when displaying the map by outputting the program having the above function to the client terminal and executing the program on the client. Can be collected.

  As shown in FIG. 4, the program may use a so-called “beacon method” in which access information is collected by accessing a beacon image using an <img> tag. In that case, the output unit of the map server device of the present embodiment preferably has an image access program output means for outputting an image access program which is a program for obtaining the URL by using access to the beacon image. As described above, the URL acquisition process can be executed in the background of the display process of the web page and map image by the browser by executing the applet type program on the client terminal and acquiring the URL. Therefore, the process can be made invisible to the user, a long and unpleasant URL can be seen by the user, the acquired URL can be arbitrarily deleted from the access address, etc. Can be prevented.

  Further, for example, even when the referrer setting capable of acquiring the referrer URL is disabled on the browser side, the URL can be acquired by executing access to the beacon image by the applet-type program or the like in this way. There is also an effect that it is possible.

  The “reception unit” (0203) has a function of receiving a map display request generated by using the tag output from the output unit and the URL transmitted by the program output from the output unit. This can be realized by an IF, CPU, main memory, reception program, and the like. Specifically, first, a map of a predetermined range centered on the latitude and longitude is stored in the map server device using, for example, latitude and longitude information of the map indicated by the tag output from the output unit at the client terminal. An image distribution request is generated. And the distribution request of the map image is received by this receiving unit.

  Further, as described above, secondly, for example, an applet type program is executed on the client terminal, whereby the URL of the referenced web page is acquired by the program. Further, when the program is executed and an access including the acquired URL is executed on the server device, the map server device of the present embodiment provides the URL of the web page for displaying the map to the receiving unit. And so on. If the URL is received as an access to the above-described beacon image, the receiving unit may include an image access receiving unit that receives an access to the beacon image.

  The “accumulation unit” (0204) has a function of associating and accumulating the URL and map identification information for identifying the map requested by the map display request. For example, a recording medium such as an HDD, a CPU, a main memory It can be realized by a storage program. The information indicating the map stored in association with the URL may be various. For example, if an identification ID is attached to each map image, it may be stored. There are various methods for associating the URL with the map identification information. For example, the program itself has a map display function, and executes a map display request using a tag output at the same time as acquisition of a URL and transmission to a server. In the server device, the map of the map display request transmitted by the same program is associated with the URL. Or in the said program, it comprises so that the map identification information shown with the tag output simultaneously with self may be acquired at the time of the output from a server apparatus. When the URL is transmitted from the client terminal, the map identification information is transmitted in association with each other, and the received server device grasps the association between the two.

  In addition, the storage unit may include a “coordinate storage unit” (not shown). The “coordinate accumulating means” further has a function of accumulating the URL of the referred web page in association with the requested center coordinates of the map, thereby accumulating the map center coordinates in association with the URL. FIG. 5 is a conceptual diagram showing an example of a database constructed by data recorded on the HDD or the like by the coordinate storage means. Of course, the data accumulated as the information indicating the map other than the center coordinates may be the coordinates of the left end of the map. Then, using such a database, for example, a service for displaying a link icon or the like to a web page associated with the position at a predetermined position on the map image can be provided.

  The “map output unit” (0205) has a function of outputting information for map display to the client in response to the received map display request, and is realized by a communication IF, CPU, main memory, and map output program. be able to. Specifically, for example, a map image for display on the client is generated from the map image database in accordance with, for example, latitude / longitude information or image size information included in the map display request, and returned.

  In this manner, the map server device according to the present embodiment outputs the map display tag and the program for collecting the map display and the access log to the client terminal according to the code embedded in the web page. Then, by receiving the URL of the program executed and transmitted and the map display request based on the tag, the database is constructed by associating the URL with the center coordinates of the map and the URL, and constructing a database. Can be returned and displayed.

<Hardware configuration>
FIG. 6 is a schematic diagram illustrating an example of the configuration of the map server device when the above functional components are realized as hardware. The operation of each hardware component in the map / URL association accumulation process will be described with reference to FIG.

  As shown in this figure, the map server device includes a “CPU” (0601) and a “main memory” (0602) for executing various arithmetic processes related to the above-described components. The storage unit also includes an “HDD” (0603), a trigger reception unit, a reception unit, and a “communication IF” (0604) as a map output unit. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  A program is read out to the “main memory”, and the “CPU” refers to the read out program and executes various arithmetic processes according to the procedure indicated by the program. In addition, a plurality of addresses are assigned to each of the “main memory” and “HDD”, and in the calculation processing of the “CPU”, the addresses are specified and accessed to store the data. It is possible to perform arithmetic processing using.

  Here, access to the blog page B introducing the restaurant is executed at the client terminal. In the blog page B, a code described by, for example, a script tag indicating latitude / longitude information for displaying a map indicating the location of the restaurant introduced in the article, address information of the map server device, etc. Is embedded. Therefore, when the user's client terminal device reads the blog page B, it generates an HTTP request according to the embedded code, and transmits it to the map server device as a trigger for displaying the map.

  Then, in the map server device according to the present embodiment, the output program is interpreted with the reception of the HTTP request as a trigger, and the applet program for acquiring the URL is combined with the tags necessary for the map display according to the interpretation result. Reply to the terminal. This applet program has a map display function and a function for acquiring the URL of the web page (blog page B in the above example) from which a trigger for map display is transmitted from a browser and transmitting it to the map server device. And.

  Therefore, this applet program generates an HTTP request which is a map display request including latitude and longitude information using the tag at the client terminal. At the same time, the applet program obtains the URL of the blog page B from which it is transmitted from the browser. And each is transmitted to a map server apparatus.

  When the map server apparatus receives an HTTP request for a map display request through the “communication IF”, the map server apparatus stores it in the address 3 of the “main memory”. In response, the “CPU” interprets the map output program. Then, according to the interpretation result, the map image indicated by the tag included in the HTTP request of the map display request is read to the address 4 of “main memory” and returned to the client terminal. In the map server device of the present embodiment, the URL of the blog page B transmitted from the client terminal by the program is also received by the “communication IF” and stored in the address 5 of the “main memory”. Then, the “CPU” interprets the stored program, and according to the interpretation result, the center coordinates of the map stored at address 4 and the URL stored at address 5 transmitted by the same program as the map display request, Are recorded in “HDD” or the like. And the map server apparatus of a present Example can construct | assemble the database as shown in FIG. 5 by it.

The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care.

  As shown in this figure, first, a predetermined map display request trigger is received from a client accessing and displaying a web page in which a map display code is embedded (step S0701). Then, in response to the reception of the trigger, a tag necessary for map display and the URL of the web page referred to when generating the trigger are acquired from the client, for example, processing such as accessing a beacon image of the map server device Is output to the client (step S0702).

  After that, when receiving a map display request generated using a tag by the program output in step S0702 and a request for acquiring a beacon image generated including a URL (step S0703), the received beacon image is received. The URL of the referenced web page is extracted from the acquisition request, and is recorded in a storage unit such as an HDD in association with the map requested in the map display request (step S0704). At the same time, in response to the received map display request, information for map display is output to the client (step S0705).
