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. A method for tagging a geographical area, the method comprising:
obtaining attribute information and mobile tracking data for one or more mobile objects, wherein the attribute information comprises a respective plurality of attributes of each of the one or more mobile objects, and wherein the mobile tracking data comprises a plurality of sampling point locations and a corresponding plurality of sampling times, wherein each sampling time corresponds to presence of a respective mobile object at a respective sampling point location; generating new mobile tracking data from the mobile tracking data by determining one or more time slices corresponding to the plurality of sampling times and associating each time slice with a corresponding one or more sampling point locations of the plurality of sampling point locations; determining a respective correspondence relationship for each of the plurality of mobile objects, each respective correspondence relationship indicating a respective number of occurrences of the respective plurality of attributes of the mobile object for each of one or more combinations of a plurality of time slice and sampling point location combinations, the plurality of combinations comprising a first combination of a particular time slice with a first sampling point location and a second combination of the particular time slice with a second sampling point location; determining a similarity between a first sampling point location and a second sampling point location with respect to the particular time slice; clustering the first sampling point location and the second sampling point location with respect to the particular time slice into the geographical area based at least in part on the similarity; and determining a set of attribute information associated with the geographical area with respect to the particular time slice based at least in part on a first set of attributes associated with the first combination and a second set of attributes associated with the second combination.
