摘要

In this paper, a new algorithm named TCSP is proposed to mine sequential patterns with different time constraints.It scans the database into memory and constructs time-index sets for efficient processing.It mines the desired sequential patterns without generating any candidates.We have evaluated the new algorithm with the well-known GSP algorithm and the DELISP algorithm for various datasets and constraints.The comprehensive experiments show that the TCSP algorithm works better and it has good scalability.
