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.

Abstract: A method for managing a region tag comprises: acquiring region identifier information of a geographic region; acquiring an attribute evaluation tag of the geographic region by a user 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; clustering region tags to generate a region time period tag of the geographic region for a time period based on that each region tag 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 region time period tags of the geographic region for time periods, respectively.
