Sequential pattern mining has been a well-studied area in data mining for over a decade. Yet researchers are still uncovering interesting problems, new algorithms and ways to improve upon existing methods. To efficiently mine long sequential patterns, closed sequential pattern mining was introduced. In this paper, the authors propose an efficient closed sequential pattern mining algorithm CSPAM by integrating the best qualities of an efficient sequential pattern mining algorithm SPAM and an efficient closed item set mining algorithm closet.
