From description-logic programs to multi-context systems

The combination of logic program-style rules with other reasoning systems has been a fertile topic of research in the last years, with the proposal of several different systems that achieve this goal. In this work, we look at two of these systems, dl-programs and multi-context systems, which address different aspects of this combination, and include different, incomparable programming constructs. We prove that every dl-program can be transformed into a multi-context system in such a way that the different semantics for each paradigm are naturally related. As a consequence, constructions developed for dl-programs can be automatically ported to multi-context systems. In particular, we show how to model default rules over ontologies with the usual semantics.
