Abstract

The present disclosure relates to a method and system for determining a final location associated with a service requester. The method includes obtaining, by at least one computer server of an online transportation service platform, an initial location associated with a service requester; comparing, by the at least one computer server, the initial location with a plurality of candidate locations in a database to generate at least one match result; and determining, by the at least one computer server, a final location based on the at least one match result, wherein the final location is associated with the initial location.

Claims

1. A system configured to operating an online transportation service platform, comprising:

a bus;

at least one storage medium electronically connected to the bus, including a set of instructions for determining a final location associated with a service requester; and

logic circuits in communication with the storage medium via the bus, wherein when executing the set of instructions, the logic circuits are directed to;

obtain electronic signals including an initial location sent from a network associated with a service requester;

compare the initial location with a plurality of candidate locations in a database to generate at least one match result; and

determine the final location based on the at least one match result, wherein the final location is associated with the initial location.

2. The system of claim 1, wherein the initial location is obtained by scanning a bar code by a user equipment associated with the service requester.

3. The system of claim 1, wherein the initial location is obtained by triggering a fix terminal in a fix location by the service requester.

4. The system of claim 1, wherein to compare the initial location with the plurality of candidate locations in the database, the logic circuits are further directed to:

determine an edit distance between the initial location and each of the plurality of candidate locations;

select, from the plurality of candidate locations, a first set of candidate locations corresponding to a first number of smallest edit distances;

determine a geographical distance between the initial location and each of the first set of candidate locations;

select, from the first set of candidate locations, a second set of candidate locations, wherein the corresponding geographical distance of each of the second set of candidate locations is smaller than a first predetermined distance; and

determine the second set of candidate locations as the least one match result.

7. The system of claim 1, wherein to determine the final location based on the at least one match result, the logic circuits are further directed to:

determine that one of the at least one match result is selected by the service requester; and

determine the selected match result as the final location.

8. The system of claim 1, wherein to determine the final location based on the at least one match result, the logic circuits are further directed to:

determine that the at least one match result is not selected by the service requester; and

determine the final location by using a map of a geographical area encompassing the initial location when the at least one processor detects that an point-selection icon is triggered.

9. The system of claim 8, wherein to determine the final location by using the map, the logic circuits are further directed to:

instruct a user equipment to call the map of the geographical area corresponding to region information of the initial location;

instruct the user equipment to display the point-selection icon on the map based on a first point-selection criteria;

instruct the user equipment to move the point-selection icon to a first position on the map in response to an operation of dragging the point-selection icon, wherein the first position is associated with a basic location; and

determine the final location based on a second point-selection criteria and the basic location.

10. The system of claim 9, wherein to determine the final location based on the second point-selection criteria and the basic location, the logic circuits are further directed to:

determine one or more second locations within a third predetermined distance from the basic location; and

determine one of the second locations or the basic location as the final location.

5. The system of 4, wherein to compare the initial location with the candidate locations in the database, the logic circuits are further directed to:

determine a central location of the second set of candidate locations based on attitudes and longitudes of the second set of candidate locations; and

determine the central location as the at least one match result.

6. The system of claim 5, wherein to compare the initial location with the candidate locations in the database, logic circuits are further directed to:

determine at least one first location that is within a second predetermined distance from the central location; and

determine the at least one first location as the at least one match result.

11. A method configured to operating an online transportation service platform, comprising:

obtaining, by at least one computer server of an online transportation service platform, electronic signals encoding an initial location associated with a service requester;

comparing, by the at least one computer server, the initial location with a plurality of candidate locations in a database to generate at least one match result; and

determining, by the at least one computer server, a final location based on the at least one match result, wherein the final location is associated with the initial location.

12. The method of claim 11, wherein the initial location is obtained by scanning a bar code by a user equipment associated with the service requester.

13. The method of claim 11, wherein the initial location is obtained by trigging a fix terminal in a fix location by the service requester.

17. The method of claim 11, wherein the determining of the final location based on the at least one match result further comprises:

determining, by the at least one computer server, that one of the at least one match result is selected by the service requester; and

determining, by the at least one computer server, that the at least one match result is not selected by the service requester; and

determining, by the at least one computer server, the final location by using a map of a geographical area encompassing the initial location when the at least one computer server detects that an point-selection icon is triggered.

19. The method of claim 18, wherein the determining of the final location by using the map further comprises:

instructing a user equipment to call, by the at least one computer server, the map of the geographical area corresponding to region information of the initial location;
