摘要： 引入序列模式时间特征的概念,并提出了一个带时间约束的序列模式挖掘算法，称做TESP(Time-enriched Sequential Pattern mining)，该算法在找出模式的同时，也给出了序列模式的时间特征，并且允许用户在挖掘之前对模式的这些时间特征进行限制，提高了序列模式挖掘的灵活性和有用性。

Abstract: In this paper, the time-enriched sequential pattern concept is introduced, and a novel mining algorithm, called TESP(time-enriched sequential pattern mining ), is developed, which also enables users to issue many time focused constraints and enhances flexibility and usefulness of sequential patterns mining.
