  The inventor has intensively studied to create the database. As a result, it has been found that common names given to predetermined areas such as street names used for roads are often used as part of the names of facilities in the vicinity of the predetermined area. Therefore, it has been conceived that, if data relating to the common name of the area is generated based on the name of the facility near the predetermined area, the common name data can be generated easily and in accordance with the actual situation.

The present invention has been made in view of the above-mentioned problems, and the first aspect is defined as follows. That is,
A nickname data generation device that generates nickname data in which a nickname of an area is associated with a predetermined area displayed on a map,
A facility data storage unit that stores facility data including the name of the facility and location information of the facility;
A first facility data extraction unit that extracts first facility data including the common name in the name of the facility from the facility data storage unit;
An area specifying unit for specifying the position information of the area based on the position information of the extracted first facility data;
A stringing unit that links the common name to the positional information of the region;
A so-called data generation device.

By generating common name data in this way, it is possible to generate common name data that is simple and suitable for the actual situation.
Here, examples of the “area” include a road, a shopping street, an underground mall, and the like.
In addition, the “common name of the area” may be a name or the like generally called in the local area or around the area as the name of the area. In the case of “XX street” as the common name, “xx passage” and the like are included as similar words.
Therefore, the common name is a street name, and the region can be a road (seventh aspect).
“Linking” refers to associating the common name and the position information of the region with each other.
The associating unit can associate the common name data with position information of a representative point associated with the region (third aspect). The representative point may be a center point of the region (fourth aspect). Furthermore, the representative point may be a center of gravity of the location of the facility obtained based on location information of a plurality of the extracted facility data (fifth aspect).

The second aspect of the present invention is defined as follows. That is,
In the common name data generation device defined in the first aspect, a second facility data extraction unit that extracts second facility data including a search element for searching for the common name from the facility data storage unit;

The first facility data extraction unit extracts first facility data including the specified common name in the name of the facility.

According to the common name data generation device of the second aspect defined in this way, the second facility data including the search element is extracted based on a predetermined search element, and the common name is automatically given from the search element. And the first facility data can be extracted based on the identified common name. According to this, even when the accurate common name is not known in advance, the common name can be automatically specified, and the specified common name can be associated with the region. The common name may be specified based on the name of the facility of the extracted second facility data in addition to the search element.
Here, the “search element” is an element for specifying a common name. For example, “street store” or the like can be used as a search element. In addition to “street store”, “dori store”, “street branch”, “highway store”, “road store”, and “bypass store” can be used as search elements.
When the search element is “street store”, the second facility data including the “street store” is extracted, and the name “XX street” is obtained from “XX street store” obtained by appropriately sorting. It can be specified.

The area specifying unit specifies an area associated with the common name based on the location information of the facility in the first facility data. For this reason, two areas that have the same common name and that are close to each other but that are apart may be identified. In such a case, it seems that it is practical to associate a common name with an area formed by connecting the two areas.
Therefore, the sixth aspect of the present invention is defined as follows. That is,
In the common name data generation device defined in any one of the first to fifth aspects, the area specifying unit specifies position information of the first target area and position information of the second target area as the position information of the area. And when the first region and the second region exist apart from each other, the positional information of the third region is specified by connecting the first region and the second region,
The association unit associates the common name with the position information of the third region.
