“…That is, they are designed to discover (and update) all association rules in a database (meeting the user-defined thresholds mentioned above) rather than allowing the user to perform targeted queries. Targeted queries are useful for applications where the user wants to discover association rules involving a subset of the items contained in a database, instead of all items [7,8]. To process targeted queries for association rule mining efficiently in the context of static or incremental databases, the Itemset Tree (IT) data structure was proposed [7,8].…”

“…Targeted association mining utilizes the itemset tree data structure, which reduces the complexity of rule mining as compared to Apriori-like algorithms [4] [5]. Previous work by Lavergne et al [6] introduced the Ordered Min-Max Itemset Tree, which takes advantage of the ordered nature of the tree as well as the range of items contained within a given subtree to reduce the search path for a given query. The query sets, known as user defined interest itemsets (UDII), represent the user's interests.…”
