Abstract: This paper proposes a novel algorithm MFSPAN (maximal frequent sequential pattern mining algorithm). MFSPAN is used to mine the com plete set of maximal frequent sequential patterns in sequence databases. It solves the problem that the number of frequent subsequences will increase explosively as frequent patterns become longer: because MFSPAN takes full advantage of the property that different sequences may share a common prefix to reduce itemset comparing times. Experiments on standard test data show that MFSPAN is very effective.
Key words: sequential pattern, maximal sequential pattern, long pattern, depthfirst
