Subjective measures, used to model interestingness of rules, are user-driven, domain-dependent, and include unexpectedness, novelty and actionability (Adomavicius and Tuzhilin 1997, Liu et al. 1997, Silberschatz and Tuzhilin 1995). Liu et al. (1997) define a rule as actionable, if a user can do an action to his/her advantage based on that rule. Their notion of actionability is too vague and leaves the door open to a number of different interpretations. Raś and Wieczorkowska (2000) assume that actionability has to be expressed in terms of attributes that are present in the database. They have introduced a new class of rules (called action rules) that are constructed from certain pairs of association rules extracted from that database. A conceptually similar definition of an action rule was proposed independently by Geffner and Wainer (1998). Action rules have been investigated further in Raś and Gupta (2002), Raś and Tsay (2003), Raś et al. (2005) and Tzacheva and Raś (2004). In order to construct action r...
