Abstract

A method is provided. The method includes: determining, by one or more computers, a name of a target region, wherein the name of the target region is determined based on geometry attribute information of the target region; and determining, by one or more computers, region attribute information of the target region based on the name of the target region.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
determining, by one or more computers, a name of a target region, based on a geometry attribute of the target region, wherein the target region is delineated based on roads or boundaries of points of interest (POI) in a real world, or by taking natural objects in the real world as boundaries, wherein the geometry attribute comprises a centroid of the target region, wherein the geometry attribute further comprises at least two of a visual center point of the target region, a first perimeter of the target region, and a first area of the target region, wherein the name of the target region comprises a first grid code and a second grid code, wherein the first grid code is determined based on the visual center point of the target region, and wherein the second grid code is determined based on at least one of the first perimeter and the first area of the target region;
determining, by one or more computers, region attribute information of the target region based on the name of the target region, wherein the region attribute information includes region portrait information obtained based on basic information of the target region, and wherein the basic information includes an area, a population, traffic information and enterprises information; and
performing recommendation based on the region portrait information of the target region, comprising:
pushing, based on the region portrait information of the target region, videos and news to a client of a demographic of the target region.

2. The method according to claim 1 , wherein the determining the first grid code based on the visual center point of the target region comprises:
determining Mercator coordinates based on coordinates of the visual center point of the target region; and
determining the first grid code based on the Mercator coordinates by using a Geohash algorithm.

3. The method according to claim 1 , wherein the determining the second grid code based on at least one of the first perimeter and the first area of the target region comprises:
determining the second grid code based on a second grid code determination rule, and at least one of the first perimeter and the first area of the target region.

4. The method according to claim 1 , wherein the first perimeter and the first area are historical data of the target region, and the method further comprises:
determining at least one of a second perimeter and a second area of the target region,

wherein the second perimeter and the second area are latest data of the target region;
determining, based on the second perimeter and the first perimeter, or the first area and the second area, whether a change in perimeter or area of the target region exceeds a threshold; and
determining a second grid code based on at least one of the first perimeter and the first area if the change does not exceed the pre-determined threshold.

5. The method according to claim 1 , wherein the visual center point represents a center point that is visually located in a maximum internally-included regular region of a polygonal region.

6. The method according to claim 1 , wherein determining the visual center point of the target region comprises:
obtaining a closed polygon representing the target region;
selecting a maximum available internally-included rectangle or circle from the closed polygon;
determining a geometric center point of the maximum available internally-included rectangle or circle; and
determining the geometric center point as the visual center point of the target region.

7. A computing device, comprising:
one or more processors; and
a memory storing one or more programs configured to be executed by the one or more processors, the one or more programs comprising instructions for performing operations comprising:
determining a name of a target region based on a geometry attribute of the target region, wherein the target region is delineated based on roads or boundaries of points of interest (POI) in a real world, or by taking natural objects in the real world as boundaries,

wherein the geometry attribute comprises a centroid of the target region, wherein the geometry attribute further comprises at least two of a visual center point of the target region, a first perimeter of the target region, and a first area of the target region, wherein the name of the target region comprises a first grid code and a second grid code, wherein the first grid code is determined based on the visual center point of the target region, and wherein the second grid code is determined based on at least one of the first perimeter and the first area of the target region;
determining region attribute information of the target region based on the name of the target region, wherein the region attribute information includes region portrait information obtained based on basic information of the target region, and wherein the basic information includes an area, a population, traffic information and enterprises information; and
performing recommendation based on the region portrait information of the target region, comprising:
pushing, based on the region portrait information of the target region, videos and news to a client of a demographic of the target region.

8. The computing device according to claim 7 , wherein the determining the first grid code based on the visual center point of the target region comprises:
determining Mercator coordinates based on coordinates of the visual center point of the target region; and
determining the first grid code based on the Mercator coordinates by using a Geohash algorithm.

9. The computing device according to claim 7 , wherein the determining the second grid code based on at least one of the first perimeter and the first area of the target region comprises:
determining the second grid code based on a second grid code determination rule, and at least one of the first perimeter and the first area of the target region.

10. A non-transitory computer-readable storage medium storing one or more programs comprising instructions that, when executed by one or more processors of a computing device, cause the computing device to perform operations comprising:
determining a name of a target region based on a geometry attribute of the target region, wherein the target region is delineated based on roads or boundaries of points of interest (POI) in a real world, or by taking natural objects in the real world as boundaries,

wherein the geometry attribute comprises a centroid of the target region, wherein the geometry attribute further comprises at least two of a visual center point of the target region, a first perimeter of the target region, and a first area of the target region, wherein the name of the target region comprises a first grid code and a second grid code, wherein the first grid code is determined based on the visual center point of the target region, and wherein the second grid code is determined based on at least one of the first perimeter and the first area of the target region;
determining region attribute information of the target region based on the name of the target region, wherein the region attribute information includes region portrait information obtained based on basic information of the target region, and wherein the basic information includes an area, a population, traffic information and enterprises information; and
performing recommendation based on the region portrait information of the target region, comprising:
pushing, based on the region portrait information of the target region, videos and news to a client of a demographic of the target region.
