Abstract

Embodiments of the present application relate to an information searching method based on geographic location, an information searching system based on geographic location, and a computer program product for searching for information based on geographic location. An information searching method based on geographic location is provided. The method includes acquiring need information and geographic location information corresponding to a mobile terminal user, looking up a preset geographic location zone threshold value based on the need information, preconfigured mappings of preset geographical location zone information and category information, and searching for target information corresponding to the need information based on the geographic location information of the mobile terminal user and the preset geographic location zone threshold value.

Claims

1. An information searching method based on geographic location, comprising:

acquiring, using one or more processors, need information and geographic location information corresponding to a mobile terminal user;

looking up, using the one or more processors, a preset geographic location zone threshold value based on the need information, preconfigured mappings of preset geographical location zone information and category information; and

searching for, using the one or more processors, target information corresponding to the need information based on the geographic location information of the mobile terminal user and the preset geographic location zone threshold value.

2. The information searching method based on geographic location as described in claim 1, wherein looking up the preset geographic location zone threshold value based on the need information comprises:

determining the category level of the finest category level to which the need information is belongs; and

looking up the preset geographic location zone threshold value corresponding to the category level of the finest category level.

3. The information searching method based on geographic location as described in claim 1, further comprising, before the acquiring of the need information and the geographic location information corresponding to the mobile terminal user, receiving a location service request sent by the mobile terminal user, the location service request including a keyword indicating the need information corresponding to a first terminal.

4. The information searching method based on geographic location as described in claim 3, wherein the acquiring of the need information corresponding to the mobile terminal user comprises:

extracting the keyword from the location service request; and

querying a local database of a server to acquire the need information corresponding to the mobile terminal user based on the keyword.

5. The information searching method based on geographic location as described in claim 3, wherein the acquiring of the need information corresponding to the mobile terminal user comprises:

extracting the keyword from the location service request; and

establishing the keyword as the need information corresponding to the mobile terminal user.

6. The information searching method based on geographic location as described in claim 1, further comprising after the looking up of the preset geographic location zone threshold value corresponding to the need information based on the geographic location information of the mobile terminal user and the preset geographic location zone threshold value and before the searching for the target information corresponding to the need information falling within the geographic location zone threshold value:

searching in a database for the product information based on the need information;

classifying the found product information into a category; and

acquiring the product type-related need information corresponding to the need information based on the category.

7. The information searching method based on geographic location as described in claim 1, further comprising after the searching for the target information corresponding to the need information falling within the geographic location zone threshold value based on the geographic location information of the mobile terminal user and the preset geographic location zone threshold value:

acquiring target information that satisfies a voice communication requirement from the found target information.

8. The information searching method based on geographic location as described in claim 7, wherein the acquiring of the target information that satisfies the voice communication requirements from the found target information comprises:

acquiring a preset activity time period corresponding to the found target information; and

regarding the target information having an activity time period including the current time as the target information that satisfies the voice communication requirement.

9. The information searching method based on geographic location as described in claim 1, further comprising:

receiving a request sent by the mobile terminal to revise the geographic location zone threshold value.

10. The information searching method based on geographic location as described in claim 1, further comprising, after the searching for the target information corresponding to the need information based on the geographic location information of the mobile terminal user and the preset geographic location zone threshold value:

providing the found target information to a mobile terminal of the mobile terminal user.

11. An information searching system based on geographic location, comprising:

at least one processor configured to;

acquire need information and geographic location information corresponding to a mobile terminal user;

look up a preset geographic location zone threshold value based on the need information, preconfigured mappings of preset geographical location zone information and category information; and

search for target information corresponding to the need information based on the geographic location information of the mobile terminal user and the preset geographic location zone threshold value; and

a memory coupled to the at least one processor and configured to provide the at least one processor with instructions.

12. The information searching system based on geographic location as described in claim 11, wherein looking up the preset geographic location zone threshold value based on the need information comprises:

determine the category level of the finest category level to which the need information belongs; and

look up the preset geographic location zone threshold value corresponding to the category level of the finest category level.

13. The information searching system based on geographic location as described in claim 11, wherein the at least one processor is configured to:

before the acquiring of the need information and the geographic location information corresponding to the mobile terminal user, receive a location service request sent by the mobile terminal user, the location service request including a keyword indicating the need information corresponding to a first terminal.

14. A computer program product for searching for information based on geographic location, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

to acquiring need information and geographic location information corresponding to a mobile terminal user;

looking up a preset geographic location zone threshold value based on the need information, preconfigured mappings of preset geographical location zone information and category information; and

searching for target information corresponding to the need information based on the geographic location information of the mobile terminal user and the preset geographic location zone threshold value.

15. The computer program product for searching for information based on geographic location as described in claim 14, wherein looking up the preset geographic location zone threshold value based on the need information comprises:

determining the category level of the finest category level to which the need information belongs; and

looking up the preset geographic location zone threshold value corresponding to the category level of the finest category level.

16. The computer program product for searching for information based on geographic location as described in claim 14, further comprising, before the acquiring of the need information and the geographic location information corresponding to the mobile terminal user, receiving a location service request sent by the mobile terminal user, the location service request including a keyword indicating the need information corresponding to a first terminal.
