摘要

Frequent sequence mining is a fundamental and essential operation in the process of discovering the sequential rules. Most of the sequence mining algorithms use apriori methodology or build the larger sequences from smaller patterns, a bottom-up approach. In this paper, we present an algorithm that uses top-down approach for mining long sequences. Our algorithm defines dominancy of the sequences and uses it for minimizing the scanning of the data set.
