Tagging geographical areas

摘要

A method of tagging a geographical area includes obtaining, with a processing device, attribute information and mobile tracking data of a plurality of mobile objects, wherein the mobile tracking data comprises sampling time and corresponding sampling point locations of the mobile objects; converting the mobile tracking data of the plurality of mobile objects into new mobile tracking data according to the correspondence relationship between the sampling time and a time slices, wherein the new mobile tracking data include time slices and corresponding sampling point locations; and obtaining a set of attribute information of at least one geographical area with respect to the time slices based on the new mobile tracking data, wherein the at least one geographical area is obtained by clustering the sampling point locations.

1. An apparatus for tagging a geographical area, comprising:
a processor implemented tracking data obtaining module configured to obtain attribute information and mobile tracking data of a plurality of mobile objects, wherein the mobile tracking data comprises sampling time and corresponding sampling point locations of the mobile objects; a processor implemented tracking data converting module configured to convert the mobile tracking data of the plurality of mobile objects into new mobile tracking data according to the correspondence relationship between the sampling time and time slices, attribute information, and occurrence times, wherein the new mobile tracking data include time slices and corresponding sampling point locations, wherein the occurrence times are based on the number of times each of the plurality of mobile object is recorded at the time slices and sampling point locations of the new mobile tracking data; and a processor implemented attribute information first obtaining module configured to obtain a set of attribute information of at least one geographical area with respect to the time slices based on the new mobile tracking data and to determine a set of attribute information of the at least one geographical area with respect to the time slice, wherein the at least one geographical area is obtained by clustering the sampling point locations, wherein the processor implemented attribute information first obtaining module comprises: an attribute information second obtaining module configured to obtain a set of attribute information of a plurality of mobile objects with respect to a same time slice and a same sampling point location based on the new mobile tracking data; and a clustering module configured to cluster sampling point locations based on a similarity between sampling point locations with respect to the same time slice to obtain at least one geographical area.
