In the present embodiment, the display control unit 68 causes the terminal 12 to display information indicating the position on the map specified by the position specifying unit 66, for example. Here, for example, the display control unit 68 may generate a map image 30 showing a position on the map specified by the position specifying unit 66. Then, the display control unit 68 may transmit the generated map image 30 to the terminal 12. Then, the terminal 12 may display the received map image 30 on the output unit 12d.

Hereinafter, an example of the flow of the process of specifying the position on the map corresponding to the residential address indicated in the search condition character string performed on the server 10 according to the present embodiment is illustrated in FIGS. 7A and 7B. Will be explained with reference to.

First, the reception unit 58 receives the search condition character string and the attribute information from the terminal 12 (S101).

Then, the V1 code specifying unit 60 identifies the V1 code included in the V1 code management data whose location partially matches the search condition character string received in the process shown in S101 (S102). Here, the V1 code is specified by referring to the V1 code management data stored in the V1 code management data storage unit 42. In the process shown in S102, the location character string and the partition character string are specified at the same time. In addition, the above-mentioned normalization process of the search condition character string is also executed.

Then, the address notation type specifying unit 62 specifies the type of address notation based on the attribute information received in the process shown in S101 (S103).

Then, the address notation type specifying unit 62 determines whether or not the type of the address notation designated by the user is unknown (S104). Here, for example, when "Unknown" is specified as the address notation type attribute, or when the address notation type attribute is not specified, it is determined that the address notation type specified by the user is unknown. You may do it.

It is assumed that it is determined in the process shown in S104 that the type of address notation specified by the user is unknown (S104: Y). In this case, the address notation type estimation unit 64 estimates the type of address notation indicated by the search condition character string for which the normalization process has been executed (S105). The estimation of the type of address notation will be described later.

Then, the position specifying unit 66 confirms whether or not the type of the address notation estimated by the process shown in S105 is the address display number (S106).

It is assumed that in the process shown in S106, it is confirmed that the type of address notation estimated in the process shown in S105 is the address display number (S106: Y). In this case, the position specifying unit 66 specifies both the lot number corresponding position and the residential address corresponding position based on the search condition character string in which the normalization process is executed (S107), and is shown in this processing example. The process is terminated. Here, both the above-mentioned lot number correspondence position identification process and the above-mentioned residence display correspondence position identification process are executed.

It is assumed that it is determined in the process shown in S104 that the type of address notation specified by the user is not unknown (S104: N). In this case, the position specifying unit 66 confirms whether or not the type of address notation specified in the process shown in S103 is a lot number (S108).

It is assumed that it is confirmed in the process shown in S108 that the type of address notation specified in the process shown in S103 is not a lot number (S108: N). In this case, the position specifying unit 66 confirms whether or not the type of address notation specified in the process shown in S103 is a house number (S109).

It is assumed that the type of address notation specified in the process shown in S103 is confirmed to be the house number in the process shown in S109 (S109: Y). In this case, the position specifying unit 66 specifies the site lot number corresponding to the house number indicated by the search condition character string on which the normalization process is executed (S110). Here, the site lot number management data is referred to, and in the site lot number management data, the lot number associated with the house number indicated by the search condition character string on which the normalization process is executed is specified.

Then, the position specifying unit 66 executes the above-mentioned lot number corresponding position specifying process, specifies the lot number corresponding position corresponding to the lot number specified in the process shown in S110 (S111), and the process shown in this processing example ends. Will be done.

It is assumed that in the process shown in S106, it is confirmed that the type of address notation estimated in the process shown in S105 is not the address display number (S106: N). Also in this case, the position specifying unit 66 executes the above-mentioned lot number corresponding position specifying process, specifies the lot number corresponding position based on the search condition character string for which the normalization process is executed (S111), and this processing example. The process shown in is terminated.

It is assumed that it is confirmed in the process shown in S109 that the type of address notation specified in the process shown in S103 is not the house number (S109: N). In this case, the type of address notation specified in the process shown in S103 is the residential addressing system. In this case, the position specifying unit 66 executes the above-mentioned residence display corresponding position identification process, specifies the residence display corresponding position based on the search condition character string for which the normalization process is executed (S112), and presents the present. The process shown in the process example is terminated.

In the processing shown in S111 and S112 in the above processing example, the position specifying unit 66 sets the value of the next best score rank data included in the processing data corresponding to the processing executed when the position on the map is specified. Also specify.

In the process shown in S110 of the above processing example, the lot number associated with the house number indicated by the search condition character string is not present, for example, when the lot number associated with the house number indicated by the search condition character string does not exist. May not be specified. In this case, even if the position specifying unit 66 executes the first lot number corresponding position specifying process, assuming that the house number indicated by the search condition character string for which the normalization process has been executed is the lot number in the process shown in S111. Good. Further, in this case, in the process shown in S111, the position specifying unit 66 also assumes that the description from the prefecture to the branch number of the house number indicated by the search condition character string on which the normalization process is executed is the lot number. The second lot number corresponding position specifying process may be executed.

Then, of the positions specified by each of the first lot number corresponding position specifying process and the second lot number corresponding position specifying process, the one with the smaller value of the next best point rank data specified together with the position on the map is S111. It may be adopted as a position on the map specified in the process shown in.

Next, an example of the flow of the estimation process of the type of address notation shown in S105 will be described with reference to the flow diagram illustrated in FIG.

First, the address notation type estimation unit 64 confirms whether or not the parent number of the address notation indicated by the search condition character string for which the normalization process has been executed is 100 or more (S201).

It is assumed that it is confirmed that the parent number of the address notation indicated by the search condition character string for which the normalization process is executed in the process shown in S201 is not 100 or more (S201: N). In this case, the address notation type estimation unit 64 confirms whether or not the parent number of the address notation indicated by the search condition character string for which the normalization process has been executed includes kanji or kana (S202). When the parent number of the address notation indicated by the search condition character string for which normalization processing has been executed includes kanji or kana, for example, the parent number of the address notation indicated by the search condition character string is "Exhibit Ko 71" or "a". 12 ”is applicable.

It is assumed that in the process shown in S202, it is confirmed that neither the kanji nor the kana is included in the parent number of the address notation indicated by the search condition character string for which the normalization process is executed (S202: N). In this case, the address notation type estimation unit 64 confirms whether or not the value of the V1 code residence display flag corresponding to the search condition character string for which the normalization process has been executed is "0" (S203). Here, for example, the value of the V1 code residence display flag included in the V1 code management data indicating the location that partially matches the search condition character string received in the process shown in S101 is confirmed.

It is assumed that the value of the V1 code residence display flag corresponding to the search condition character string for which the normalization process has been executed is not "0" (that is, "1") (S203: N). In this case, the area to which the location corresponding to the search condition character string belongs is the residential addressing system area. Therefore, in this case, the address notation type estimation unit 64 estimates the type of the address notation indicated by the search condition character string for which the normalization process has been executed as the residence display number (S204), and the process shown in S105 is completed.

When the value of the V1 code specified in the process shown in S102 is NULL, the value of the V1 code residence display flag cannot be confirmed in the process shown in S203. Also in this case, the address notation type estimation unit 64 estimates the type of address notation indicated by the search condition character string for which the normalization process has been executed as the residential addressing system number (S204), and the process shown in S105 is completed.

It is assumed that in the process shown in S201, it is confirmed that the parent number of the address notation indicated by the search condition character string for which the normalization process is executed is 100 or more (S201: Y). In this case, the address notation type estimation unit 64 estimates the type of the address notation indicated by the search condition character string for which the normalization process has been executed as the lot number (S205), and the process shown in S105 is completed.

It is assumed that in the process shown in S202, it is confirmed that the parent number of the address notation indicated by the search condition character string for which the normalization process has been executed includes kanji or kana (S202: Y). Also in this case, the address notation type estimation unit 64 estimates the type of the address notation indicated by the search condition character string for which the normalization process has been executed as the lot number (S205), and the process shown in S105 is completed.

It is assumed that the value of the V1 code residence display flag corresponding to the search condition character string for which the normalization process has been executed is confirmed to be "0" in the process shown in S203 (S203: Y). In this case, the area to which the location corresponding to the search condition character string belongs is not the residential addressing system area but the lot number area. Therefore, also in this case, the address notation type estimation unit 64 estimates the type of the address notation indicated by the search condition character string for which the normalization process has been executed as the lot number (S205), and the process shown in S105 is completed.

For example, suppose that the search condition character string for which the normalization process is executed is "5-1234-5 Minamiedo, Matsuyama City, Ehime Prefecture", and "lot number" is specified as the address notation type attribute. In this case, in the lot number corresponding position specifying process, the process corresponding to the processing data having the processing number 1 is executed, and the lot number corresponding position is specified. Further, 1 is specified as the value of the next best score rank data.

Further, for example, it is assumed that the search condition character string for which the normalization process is executed is "5-1234-5 Minamiedo, Matsuyama City, Ehime Prefecture", and the address notation type attribute is unknown. In this case, since the parent number of the search condition character string is 1234, the type of address notation is presumed to be the lot number. Then, in the lot number corresponding position specifying process, the process corresponding to the processing data having the processing number 1 is executed, and the lot number corresponding position is specified. Further, 1 is specified as the value of the next best score rank data.

Further, for example, it is assumed that the search condition character string for which the normalization process is executed is "4-3-7 Yamagoe, Matsuyama City, Ehime Prefecture", and "residential addressing system number" is specified as the address notation type attribute. In this case, in the residential addressing system position identification process, the process corresponding to the process data whose process number is 3 is executed. Here, it is assumed that the position corresponding to the residential address cannot be specified in the process. Then, the process corresponding to the process data whose process number is 4 is executed. Then, the position corresponding to the residential addressing system is specified by the process corresponding to the process data in which the process number is 4. Further, 2 is specified as the value of the next best score rank data.

Further, for example, it is assumed that the search condition character string for which the normalization process is executed is "4-105-1-1 Yamagoe, Matsuyama City, Ehime Prefecture", and the address notation type attribute is "house number". Then, it is assumed that the site lot number corresponding to the house number could not be specified by the process shown in S110. In this case, the lot number corresponding position identification process is executed using each of "4-15-1 Yamagoe, Matsuyama City, Ehime Prefecture" and "4-15-1 Yamagoe, Matsuyama City, Ehime Prefecture" as keys.

Here, in the lot number corresponding position identification process for "4-105-1-1 Yamagoe, Matsuyama City, Ehime Prefecture", it is assumed that the lot number corresponding position could not be specified in the process corresponding to the processing data whose processing number is 1. Then, it is assumed that the lot number corresponding position can be specified by the processing corresponding to the processing data whose processing number is 2. In this case, 2 is also specified as the value of the next best score rank data.

On the other hand, in the lot number corresponding position identification process for "4-15-1 Yamagoe, Matsuyama City, Ehime Prefecture", it is assumed that the lot number corresponding position can be specified by the process corresponding to the processing data whose processing number is 1. In this case, 1 is also specified as the value of the next best score rank data.

From the above, the lot number corresponding position specified by the lot number corresponding position identification process for "4-105-1 Yamagoe, Matsuyama City, Ehime Prefecture", where the value of the next best score rank data specified together with the position on the map is small, is in S111. It will be adopted as the position specified by the process.

If the address notation type is not specified, as in the case where the user does not know the address notation type indicated by the search condition character string, the reference data to be referred to in the location search cannot be specified, and as a result, the reference data to be referred to cannot be specified. The position that is the search result cannot be specified accurately.

Based on this, in the present embodiment, as described above, the address notation type estimation unit 64 uses the type of the address notation indicated by the search condition character string based on the parent number of the address notation indicated by the search condition character string. To estimate. Then, the position specifying unit 66 refers to the reference data in which the estimated type of address notation and the position on the map are associated with each other, so that the position on the map corresponding to the address notation indicated by the search condition character string is used. To identify.

In this way, according to the present embodiment, even if the type of the address notation indicated by the search condition character string is not specified, the position which is the search result of the search condition character string can be accurately specified.

If the parent number of the address notation is 100 or more, or if the parent number of the address notation includes kanji or kana, the area represented by the address notation is likely to be a lot number area. Based on this, in the present embodiment, as described above, the address notation type estimation unit 64 has the address notation whose master number indicated by the search condition character string is 100 or more, or the address notation indicated by the search condition character string. It is estimated whether the address notation indicated by the search condition character string is a lot number or a residential address based on whether or not the parent number includes kanji or a pseudonym. For example, the condition that the parent number of the address notation indicated by the search condition character string is 100 or more, or that the parent number of the address notation indicated by the search condition character string contains kanji or kana is satisfied. In this case, it is presumed that the address notation indicated by the search condition character string is the lot number (see S201, S202, and S206). In this way, it is possible to accurately estimate whether the type of address notation indicated by the search condition character string is a lot number or a residential address.

Further, in the present embodiment, it is conceivable that the lot number is specified even in the address display implementation area. Based on this, in the present embodiment, when it is presumed that the search condition character string indicates the residence display number, the location identification unit 66 performs the lot number correspondence position identification process in addition to the residence display correspondence position identification process. Further execution (see S106 and S107). Here, in the residence display corresponding position identification process, the position corresponding to the address notation indicated by the search condition character string specified by referring to the residence display reference data is specified. Then, in the lot number position correspondence process, the position corresponding to the address notation indicated by the search condition character string is specified by referring to the lot number reference data.

In this case, the map image 30 in which the two markers 32 indicating the lot number corresponding position and the residential address corresponding position are arranged may be displayed on the terminal 12.

Further, in the present embodiment, when accepting the search condition character string indicating the house number, the position specifying unit 66 specifies the lot number corresponding to the house number by referring to the site lot number management data (see S110).

Here, as described above, when the lot number corresponding to the house number is specified, the position specifying unit 66 specifies the lot number corresponding position including the process of specifying the position associated with the lot number in the lot number reference data. The process may be executed.

Further, when the lot number corresponding to the house number is not specified, the position specifying unit 66 identifies the position on the map associated with the lot number corresponding to the house number indicated by the search condition character string in the lot number reference data. You may execute the lot number correspondence position identification processing including. Further, in this case, the position specifying unit 66 further specifies the position on the map associated with the lot number corresponding to the part from the prefecture to the branch number of the house number indicated by the search condition character string in the lot number reference data. A second lot number corresponding position specifying process including the process may be executed. Then, in this case, the map image 30 in which the two markers 32 representing the designated positions are arranged may be displayed on the terminal 12. Further, as described above, the map image 30 in which the two markers 32 indicating the smaller value of the next best score rank data specified together among the two specified positions is arranged is displayed on the terminal 12. You may do so.

The present invention is not limited to the above-described embodiment.

For example, when there is reference data in which the house number and the polygon are associated with each other, the polygon corresponding to the house number indicated by the search condition character string may be specified in the reference data. Then, the position of the representative point of the polygon on the map may be specified.

Further, for example, the division of roles between the server 10 and the terminal 12 is not limited to the above. For example, map data may be stored in the terminal 12. Then, the position information on the map and the value of the next best score rank data may be transmitted from the server 10 to the terminal 12. Then, the terminal 12 may generate the map image 30 based on the transmitted position information on the map and the map data. Then, the terminal 12 may display the map image 30 on the output unit 12d.
