Rule Based Computation of Updates to Terminologies
In this paper we formalise compilation of the conjunctive bodies of a restricted class of Horn rules into updates on terminologies. This involves a pre-processing of the graphs re...

On the Semantic Relationship between Datalog and Description Logics
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 o...
