Abstract

We investigate query reformulation rules in OBDA to obtain either more or less answers. We extend DL-Lite with complex role inclusions and define rules that produce query relaxations/restrictions over any dataset.We also introduce a set of data-driven rules to get more fine-grained reformulations.
