摘要： In a data processing system, association rules are used to determine correlations of attributes of collected data, thereby extracting insightful information therefrom. In solving an optimized association rule problem where multiple instantiations for at least one uninstantiated attribute are required, unlike prior art, not all possible instantiations are considered to realize an optimized set of instantiations. Rather, using inventive pruning techniques, only selected instantiations need to be considered to realize same. In accordance with the invention, instantiations are assigned weights and are subject to pruning in an order dependent upon their weight. The weighted instantiations are tested based on selected criteria to identify, for example, those instantiations, consideration of which for the optimized set would be redundant in view of other instantiations to be considered. The identified instantiations are disregarded to increase the efficiency of determining the optimized set.
