PrefixSpan: Mining Sequential Patterns by Prefix-Projected Pattern
2011
International Journal of Computer Science & Engineering Survey
Sequential pattern mining discovers frequent subsequences as patterns in a sequence database. Most of the previously developed sequential pattern mining methods, such as GSP, explore a candidate generation-and-test approach [1] to reduce the number of candidates to be examined. However, this approach may not be efficient in mining large sequence databases having numerous patterns and/or long patterns. In this paper, we propose a projection-based, sequential pattern-growth approach for efficient
