Alternatively, the terminal apparatuses 101, 102, and 103 may store an address database, and the terminal apparatuses 101, 102, and 103 may determine the matching address information from the address database based on the policy user address and the address database stored locally.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
The above-described acquisition process of the address database will be described below.
Fig. 2 is a flowchart of an address matching method for a policy holding user according to an embodiment of the present invention. The execution subject of the method can be an electronic device, such as a server or a terminal device. As shown in fig. 2, the method of the present embodiment includes:
step 201, acquiring N five-level administrative areas in a preset geographic area, and dividing each five-level administrative area into a plurality of grid areas.
Wherein N is greater than or equal to 1.
The preset geographic area is an area where the address database is to be established, and may be, for example, an area where a country is located, and the following description will take a national area of china as an example. The administrative district is a region divided by countries for hierarchical management, and the administrative district of China is divided according to five levels of administrative districts of province, city, county (district), town (street) and village (community), so when the preset geographic region is the region where China is located, the five levels of administrative districts refer to the administrative district divided according to five levels of administrative districts of province, city, county (district), town (street) and village (community). It should be noted that, when the preset geographic area is another country or region, the five-level administrative district in the present application corresponds to the administrative district division manner of the country or region.
Specifically, when an address database is established for a preset geographic area, all five-level administrative area names in the preset geographic area are obtained first, wherein the five-level administrative area names include names of all levels of administrative areas to which the five-level administrative area names belong, and then, an area corresponding to each five-level administrative area is divided into at least two grid areas, wherein the shape corresponding to the grid areas is not limited in the application, for example, the shape corresponding to the grid areas can be a square or other polygons. When the address database of the chinese area is established, the names of all five-level administrative districts in china are first obtained, that is, all the names of provinces, cities, counties, towns, villages (communities) including the provinces, cities, counties (districts) and towns to which the five-level administrative districts belong are included, for example, for the XX village, the name of the XX village is XX village XX town XX village in XX city XX district. Then, the area corresponding to each five-level administrative district is divided into a plurality of grid areas.
Optionally, the grid areas within the same five-level administrative district are of the same density.
Step 202, obtaining address information of the intersections of the grid areas, wherein the address information comprises names of five-level administrative districts to which the intersections belong and longitude and latitude of the intersections.
Specifically, the corresponding position of each intersection point of each grid area on a preset geographic area and the longitude and latitude of the corresponding position are determined, then the name of a five-level administrative district of an area to which the corresponding position of each intersection point on the preset geographic area belongs is determined, a mapping relation between the longitude and latitude of each intersection point of each grid area and the name of the five-level administrative district of each intersection point is established, and the address information of each intersection point of each grid area is obtained, wherein the address information comprises the name of the five-level administrative district corresponding to each intersection point of each grid area and the longitude and latitude of each intersection point.
Fig. 3 is a schematic diagram for establishing a mapping relationship according to an embodiment of the present invention. Diagram a in fig. 3 shows the intersections of six grid areas, respectively intersection 1, intersection 2, intersection 3, intersection 4, intersection 5, and intersection 6. Wherein the latitude and longitude of the intersection of each grid area is determined. The diagram B in fig. 3 shows three preset geographical areas adjacent to each other, namely, a five-level administrative district a, a five-level administrative district B, and a five-level administrative district C. Wherein the name of each five-level administrative district is known. The diagram c in fig. 3 shows the position of the intersection points of the six grid areas in the diagram a in the three five-degree administrative districts shown in the diagram b, which are adjacent to each other. As shown in fig. C, the name of the five-degree administrative district located at the intersection 1 in the five-degree administrative district a, the names of the five-degree administrative districts located at the intersections 4, 5, and 6 in the five-degree administrative district B, and the names of the five-degree administrative districts located at the intersections 2 and 36 in the five-degree administrative district C are determined based on the longitude and latitude of the intersection of each grid area and the name of the five-degree administrative district of each five-degree administrative district. Wherein the names of the five-level administrative districts located at the intersection in the same five-level administrative district are the same. Table 1 shows a mapping relationship between the intersection point and the name of the five-stage administrative district in fig. 3.
Table 1 table of mapping relationship between intersection points and names of five-level administrative districts
| Cross point numbering | Name (R) | Encoding | Function(s) | Five-level administrative district numbering |
| 1 | A | |||
| 2 | C | |||
| 3 | C | |||
| 4 | B | |||
| 5 | B | |||
| 6 | B |
Step 203, generating the address database according to the address information of the intersection points of the plurality of grid areas.
Specifically, when the address information of the intersections of the multiple grid areas is obtained, there may be a case where the corresponding positions of the intersections of the multiple grid areas on the preset geographic area are located in the same five-level administrative district, but because the longitude and latitude of the intersection of each grid area are different, the same five-level administrative district may correspond to the longitude and latitude of the intersections of the multiple grid areas in the generated address database.
The format for storing the address information in the address database may be longitude and latitude of an intersection of the grid area and a five-level administrative district name corresponding to the intersection. Therefore, the address database can be used for matching specific addresses and can be used for matching longitude and latitude, namely a five-level administrative district name corresponding to the longitude and latitude closest to the longitude and latitude is found in the address database.
And step 204, according to the policy user address, determining the address information of a cross point from the address database as the address information matched with the policy user address.
Specifically, when address information matching with the address of the policy user is found in the address database, comparison may be performed according to the levels of five administrative districts from high to low, and when the level of the five administrative districts higher by one is the same, the level of the five administrative districts of the next level is compared, so as to find the address information matching with the address of the policy user. For example, the comparison is performed in the order of the province, city, county (district), town (street), and village (community).
In this embodiment, by acquiring information of N five-level administrative areas in a preset geographic area, dividing each five-level administrative area into a plurality of grid areas, then acquiring address information of intersections of the plurality of grid areas, where the address information includes names of the five-level administrative areas to which the intersections belong, generating an address database of the area according to the address information of the intersections of the plurality of grid areas, and finally matching the address of the policy user by using the address database. Because each five-level administrative district is provided with a plurality of grid areas, the number of the cross points of the grid areas is certainly larger than the number N of the five-level administrative districts in the geographical area needing to establish the address database, each five-level administrative district can be covered, so that the address information of all the five-level administrative districts can be obtained through the cross points of the grid areas, even for a large-range remote district, the specific address information can be obtained, the accuracy of the matched address information can be improved, the accuracy of the matched address information can be ensured when the address database is used for matching the user addresses on the insurance policy, and the insurance policy is finally distributed to correct exhibition staffs.
In some embodiments, an implementation manner of acquiring N five-level administrative areas in the preset geographic area and dividing each five-level administrative area into a plurality of grid areas in step 201 is as follows:
step 2011, obtaining a map of a preset geographic area;
step 2012, obtaining maps of the N five-level administrative areas from the maps of the preset geographic area;
and 2013, dividing each five-level administrative district into a plurality of grid areas according to the N maps of the five-level administrative districts.
The present embodiment is described by taking an example of establishing an address database of a chinese area, wherein fig. 4 is a schematic diagram of a grid area of a divided chinese map according to an embodiment of the present invention.
Specifically, a chinese map and names of all five-level administrative districts in china are obtained first, and the regional ranges of all levels of administrative districts in the five-level administrative districts are displayed on the chinese map, where, due to the limitations of the picture size and the display definition, only the regional ranges of each province in units of provincial administrative districts are shown in fig. 4. Then, as shown in fig. 5, the map of each five-level administrative district is divided into at least two grid areas, wherein the grid areas in each five-level administrative district are the same in size, and the grid areas in any two five-level administrative districts may be the same in size or different in size, and may be determined according to factors such as the area range, population density, and the like of the five-level administrative district. Fig. 5 shows a case where the grid areas in any two five-degree administrative districts are the same in size.
In some embodiments, one implementation of obtaining the address information of the intersection of the plurality of grid regions in step 202 is:
step 2021, acquiring longitude and latitude information of the intersections of the plurality of network areas;
step 2022, acquiring the address information of the intersection according to the longitude and latitude information of the intersection.
Fig. 6 is a schematic diagram of intersections of grid areas on a chinese map according to an embodiment of the present invention, and as can be seen from fig. 4 and 5, a plurality of intersections of grid areas are displayed on a map of each five-level administrative district.
Specifically, the longitude and latitude information of the location of the intersection is obtained according to the specific location of the intersection on the map, and then the name of the five-level administrative district of the location of the intersection can be determined according to the name of the five-level administrative district obtained in step 201, so that the name of the five-level administrative district corresponding to the longitude and latitude information can be determined, and thus the address information of the intersection, that is, the longitude and latitude of the intersection and the name of the five-level administrative district, is obtained.
In step 2022, one embodiment of obtaining the address information of the intersection according to the longitude and latitude information of the intersection is as follows:
step 20221, determining a five-level administrative area in which the longitude and latitude information of the intersection falls;
step 20222, using the name of the five-level administrative district as the address Information of the intersection by the overlay analysis function in the space analysis function of the Geographic Information System (GIS for short).
Referring to the prior art for introduction of a superposition analysis function in a GIS spatial analysis function, after the longitude and latitude of a cross point of a grid area and the position of the cross point in a preset geographic area are determined, a mapping relation is established between the longitude and latitude of the cross point and the name of a five-level administrative district of the preset geographic area position of the cross point by using a point and polygon superposition function in the superposition analysis function, namely the name of the five-level administrative district where the longitude and latitude are located can be inquired through the longitude and latitude, and the stored longitude and latitude located in the five-level administrative district can be inquired through the name of the five-level administrative district.
Fig. 7 is a flowchart of a method implemented in step 204 according to an embodiment of the present invention. As shown in fig. 7, in some embodiments, one implementation of step 204 may be:
and 2041, acquiring the input insurance policy user address.
Specifically, when the user inputs the policy user address, the user not only inputs the name of the five-level administrative district of the policy user address, but also inputs the name of the urban administrative district in the policy user address, for example, the prefecture county, the Hubei province, the county.
And 2042, performing word segmentation on the insurance policy user address according to the grade of the five-grade administrative district.
Specifically, the policy user address is divided into words according to the level of province, city, county (district), town (street) and village (community). For example, the word "prefecture village happy district in the city of shang cheng city of northwest of a lake" is "prefecture of hubei province/salt ning city/shang cheng county/prefecture village/happy district.
And 2043, matching the word-segmented policy keeping user address with address information in the address database.
Specifically, comparison is performed according to the levels of five administrative districts from high to low, and when the levels of the five administrative districts of the higher level are the same, the levels of the five administrative districts of the next level are compared, so that address information matched with the address of the policy user is found.
