Abstract

Different from existing utility mining techniques with a single minimum utility criterion, this work presents a new utility-based framework that allows users to specify different minimum utility thresholds to items according to the characteristics or importance of items. In particular, the viewpoint of minimum constraints in traditional minimum utility mining is extended to decide the proper criterion for an itemset in mining when its items have different criteria. In addition, an effective mining approach is proposed to cope with the problem of multi-criteria utility mining. The experimental results show the effectiveness of the proposed viewpoint and approach under different parameter settings.
