This provides a way of learning ground acyclic ProbLog programs from interpretations: first the interpretations are represented in tabular form, then a Bayesian network learning algorithm is applied and the learned network is translated into a ground ProbLog program. The program is then further analyzed in order to identify noisy or relations in it. The paper proposes an algorithm for such identification and presents an experimental analysis of its computational complexity.} }

In this paper we consider a dataset regarding periodontitis, that includes the analysis of nine genetic markers for 148 individuals. We analyze these data by using a novel subgroup discovering algorithm, named APRIORI-B, that is based on APRIORI and bootstrap techniques. This algorithm can use different metrics for rule selection. Experiments conducted by using as rule metrics novelty and confirmation, confirmed some previous results published on periodontitis.}, keywords = {Data Mining, Functional Genomics, Marker Analysis, Periodontitis} }
