Abstract
A data processing system processes data sets (such as low-resolution transaction data) into high-resolution data sets by mapping generic information into attribute-based specific information that may be processed to identify frequent sets therein. When association rules are generated from such frequent sets, the complexity and/or quantity of such rules may be managed by removing redundancies from the rules, such as by removing rules providing only trivial associations, removing rules having only a part group as the consequent, modifying rules to remove redundant antecedent items and/or filtering subsumed rules from the generated rule set that do not provide sufficient lift to meet an adjustable specialization lift threshold requirement.
