【Abstract】 Discovery of sequential patterns is becoming increasingly useful in many scientific and commercial domains.However,parallel formulations of the efficient projection-based algorithms has received little attention.The paper briefly introduces the basic concept of frequent sequence mining,then presents a distributed-memory parallel sequence mining algorithm.Moreover,a detailed analysis of the performance for the algorithm is proposed in this paper.更多还原
