摘要: A probabilistic method for inferring common routes from mobile communication network traffic data is presented. Besides providing mobility information, valuable in a multitude of application areas, the has dual purpose enabling efficient coarse-graining as well anonymisation by mapping individual sequences onto routes. The approach to represent spatial trajectories Cell ID that are grouped into using locality-sensitive hashing and graph clustering. demonstrated be scalable, accurately group an evaluation set GPS tagged data.
