Rules with Bounded Negations and the Coverage Inference Scheme
Barcelona. Work package 1. May 2002.

Abstract: We develop an experimental study of the combination of the Coverage Inference Scheme proposed by Cristofor and Simovici with the bounded-negation association rules proposed by Fortes, Balcázar, and Morales. Our main contributions are:

• A fully independent experimental validation of the advantages of the Coverage Inference Scheme on two different datasets.
• An experimental validation of the interest of the bounded-negation association rules.
• An assessment of the applicability of the Coverage Inference Scheme to bounded-negation association rules.

Our results clearly indicate that this Inference Scheme can be advantageously used to summarize association rules as the authors suggest, and that its combination with bounded-negation association rules helps overcome the associated problem of handling a large number of output rules.
