A New Approach for Resolving Conflicts in Actionable Behavioral Rules

Abstract EN

Knowledge is considered actionable if users can take direct actions based on such knowledge to their advantage.

Among the most important and distinctive actionable knowledge are actionable behavioral rules that can directly and explicitly suggest specific actions to take to influence (restrain or encourage) the behavior in the users’ best interest.

However, in mining such rules, it often occurs that different rules may suggest the same actions with different expected utilities, which we call conflicting rules.

To resolve the conflicts, a previous valid method was proposed.

However, inconsistency of the measure for rule evaluating may hinder its performance.

To overcome this problem, we develop a new method that utilizes rule ranking procedure as the basis for selecting the rule with the highest utility prediction accuracy.

More specifically, we propose an integrative measure, which combines the measures of the support and antecedent length, to evaluate the utility prediction accuracies of conflicting rules.

We also introduce a tunable weight parameter to allow the flexibility of integration.

We conduct several experiments to test our proposed approach and evaluate the sensitivity of the weight parameter.

Empirical results indicate that our approach outperforms those from previous research.
