In our paper we aim at the discovery of partially-ordered sequential rules which satisfy a given correlation gap constraint. Applying this constraint to the support threshold determines a more relevant rule, among other parameters. We also require it in sparse datasets, where long sequences with many distinct events exist. By focusing on the gap size between antecedent and consequent of a rule, we show that the resulting vast number of rules gets highly reduced while keeping the flexibility between a minimum and a maximum distance in between.
