A Novel Algorithm for Efficiently Sequential Pattern Mining : IESE-Span
검색

    초록·키워드

    this paper proposed an IESE-Span algorithm using frequent itemsets to mine sequential patterns. This algorithm redefines the length of sequence and increases the granularity of mining sequential patterns. At first, this algorithm mines all the frequent itemsets as the increasing unit in the process of sequential pattern mining. Position information of frequent 2-itemsets (or sequences) is represented by frequent 2-itemsets (or sequences)-adjacency matrix and support degree of sequence is calculated by positions sets. Experiments show that the proposed algorithm is better in both time and space performance compared to traditional sequential pattern mining algorithm.
