A New Kind of Emerging Pattern of Change Mining and Its Mining Algorithm

According to the fact that users are interested in the changes of multiple interest measures of association rules,a new kind of emerging pattern is presented which considers not only the changes of support but also the changes of confidence and other measures.Based on the Pareto sorting,a corresponding mining algorithm for Emerging Pattern is designed.Empirical evaluation shows that the proposed algorithm is very effective to recognize emerging patterns from two-period datasets.
