Since its introduction, frequent set mining has been generalized to many forms, including online mining with Carma, and constrained mining with CAP. Regardless, scalability is always an important aspect of the development. In this paper, we propose a novel structure called segment support map to help mining of frequent itemsets of the various forms. A light-weight structure, the segment support map improves the performance of frequent-set mining algorithms by: (i) obtaining sharper bounds on the support of itemsets, and/or (ii) better exploiting properties of constraints. Our experimental results show the effectiveness of the segment support map.
