“…Frequent itemset mining (Agrawal & Srikant, 1994;Cho, Pei, & Wang, 2005;Han, Cheng, Xin, & Yan, 2007) is a fundamental and primary research topic in data mining. It started as a phase in the discovery of association rules (Ashrafi, Taniar, & Smith, 2007;Daly & Taniar, 2004;Jiang, Hu, Wei, Song, Han, & Liang, 2011;Taniar, Rahayu, Lee, & Daly, 2008;Tjioe & Taniar, 2005;Vo, Hong, & Le, 2013), but has since been generalized, independent of these, to many other patterns, for example, frequent sequences (Al-Mulla & Aghbari, 2011;Lu, Chen, Adjei, & Keech, 2008), episodes (Tatti & Cule, 2012), movement pattern (Taniar & Goh, 2007), and frequent subtree (Nguyen & Yamamoto, 2012;Xiao, Yao, & Yang, 2005).…”
