A parallel algorithm for mining user frequent moving patterns
-
Abstract
Through daily moving trajectories, one can effectively find the frequent moving rules, i.e., user frequent moving patterns. Based on PrefixSpan algorithm, a parallel algorithm named PASFORM is presented for mining user frequent moving patterns. PASFORM uses a new pruning strategy to reduce the search space and several time constraints to make mining results time-tagged. It also employs the parallel method to mine mass data and a prefix tree to save the store space. Experimental results show that PASFORM is effective and efficient.
