Abstract

A method for managing a region tag may comprise acquiring a region identifier information of a geographic region, acquiring an attribute evaluation tag of the geographic region by a user whose geographic position is in the geographic region and a time identifier of the attribute evaluation tag, integrating the region identifier information, the attribute evaluation tag, and the time identifier thereof into a region tag of the geographic region, and clustering region tags of the geographic region in a time domain comprising one or more time periods to generate a region time period tag of the geographic region for each time period.

First claim

The invention claimed is:

1. A method for managing a region tag, comprising:
acquiring region identifier information of a geographic region;
acquiring an attribute evaluation tag of the geographic region by a user whose geographic position is in the geographic region and a time identifier of the attribute evaluation tag, and scoring the attribute evaluation tag to obtain a score of the attribute evaluation tag, wherein the score of the attribute evaluation tag comprises a ratio of a number of the attribute evaluation tag to a total number of all attribute evaluation tags;
integrating the region identifier information, the attribute evaluation tag, and the time identifier thereof into a region tag of the geographic region;
clustering one or more region tags to generate a region time period tag of the geographic region for a time period based on that each of the one or more region tags comprises the region identifier information of the geographic region and a time identifier within the time period, wherein the region time period tag of the geographic region for the time period corresponds to a function attribute of the geographic region for the time period; and
outputting one or more region time period tags of the geographic region for one or more time periods, respectively.

2. The method for managing a region tag according to claim 1 , wherein the acquiring an attribute evaluation tag of the geographic region by a user whose geographic position is in the geographic region and a time identifier of the attribute evaluation tag comprises:
acquiring social media data information of the user whose geographic position is in the geographic region; and
obtaining, from the social media data information, evaluation information by the user of a function attribute of the geographic region, using the evaluation information as the attribute evaluation tag of the geographic region, obtaining a time of the attribute evaluation tag from the social media data information, and using the time as the time identifier.

3. The method for managing a region tag according to claim 1 , after the acquiring an attribute evaluation tag of the geographic region by a user whose geographic position is in the geographic region and a time identifier of the attribute evaluation tag, further comprising:
classifying attribute evaluation tags of the geographic region into at least one tag class; and
normalizing attribute evaluation tags in each of the at least one tag class.

4. The method for managing a region tag according to claim 1 , wherein the scoring the attribute evaluation tag to obtain a score of the attribute evaluation tag comprises:
counting a number of attribute evaluation tags of the geographic region; and
calculating, according to the number of attribute evaluation tags, an occupancy rate of the attribute evaluation tag in the attribute evaluation tags of the geographic region, and using the occupancy rate as the score of the attribute evaluation tag.

5. The method for managing a region tag according to claim 1 , after the acquiring an attribute evaluation tag of the geographic region by a user whose geographic position is in the geographic region and a time identifier of the attribute evaluation tag, further comprising:
selecting at least one attribute evaluation tag with a highest score as the attribute evaluation tag of the geographic region.

6. The method for managing a region tag according to claim 1 , after the acquiring an attribute evaluation tag of the geographic region by a user whose geographic position is in the geographic region and a time identifier of the attribute evaluation tag, further comprising:
separately determining whether the score of each attribute evaluation tag of the geographic region is lower than a preset threshold;
in response to determining that a score of an attribute evaluation tag of the geographic region is lower than the preset threshold, eliminating the attribute evaluation tag from attribute evaluation tags of the geographic region; and
in response to determining that a score of an attribute evaluation tag of the geographic region is not lower than the preset threshold, using the attribute evaluation tag as the attribute evaluation tag of the geographic region.

7. The method for managing a region tag according to claim 1 , wherein the integrating the region identifier information, the attribute evaluation tag, and the time identifier thereof into a region tag of the geographic region comprises:
separately determining whether each attribute evaluation tag of the geographic region has a respective time identifier;
in response to determining that an attribute evaluation tag of the geographic region has a respective time identifier, integrating the attribute evaluation tag, the respective time identifier thereof, and the region identifier information into a database, and generating the region tag of the geographic region; and
in response to determining that an attribute evaluation tag of the geographic region does not have a respective time identifier, eliminating the attribute evaluation tag from attribute evaluation tags of the geographic region.

8. The method for managing a region tag according to claim 7 , wherein in response to determining that an attribute evaluation tag of the geographic region has a respective time identifier, the integrating the attribute evaluation tag, the respective time identifier thereof, and the region identifier information into a database comprises:
writing a data combination of the attribute evaluation tag, the respective time identifier thereof, and the region identifier information as a data record into a data table of the database, to serve as the region tag of the geographic region;
wherein, a primary key in the data table is the region identifier information.

9. The method for managing a region tag according to claim 1 , after the integrating the region identifier information, the attribute evaluation tag, and the time identifier thereof into a region tag of the geographic region, further comprising:
counting a number of region tags of the geographic region; and
calculating, according to the number of region tags, an occupancy rate of each region tag in the region tags of the geographic region.

10. The method for managing a region tag according to claim 9 , after the integrating the region identifier information, the attribute evaluation tag, and the time identifier thereof into a region tag of the geographic region, further comprising:
separately determining whether the occupancy rate of each region tag of the geographic region is higher than a preset threshold;
in response to determining that an occupancy rate of a region tag of the geographic region is higher than the preset threshold, maintaining the region tag as the region tag of the geographic region; and
in response to determining that an occupancy rate of a region tag of the geographic region is not higher than the preset threshold, eliminating the region tag from the region tags of the geographic region.

11. The method for managing a region tag according to claim 1 , wherein clustering one or more region tags comprises:
fuzzifying date information recorded in the one or more region tags of the geographic region;
sequencing the one or more region tags according to a chronological order of time identifiers recorded in the region tags; and
clustering the sequenced one or more region tags in the time domain comprising one or more time periods to generate a region time period tag of the geographic region for each time period;
wherein the region time period tag is a description about a function attribute of the geographic region for each time period; one region
