Abstract

Translations to (first-order) Datalog have been used in a number of inferencing techniques for description logics (DLs), yet the relationship between the semantic expressivities of function-free Horn logic and DL is understood only poorly. Although Description Logic Programs (DLP) have been described as DLs in the 'expressive intersection' of DL and Datalog, it is unclear what an intersection of two syntactically incomparable logics is, even if both have a first-order logic semantics. In this work, we offer a characterisation for DL fragments that can be expressed, in a concrete sense, in Datalog. We then determine the largest such fragment for the DL and provide an outlook on the extension of our methods to more expressive DLs.
