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...
Following the approaches and motivations given in recent works about action languages over description logics, we propose an action formalism based on a constructive semantics for ...
Abstract. We introduce a nonmonotonic framework for belief revision in which reasoning about the reliability of different pieces of information based on meta-knowledge about the in...
We prove co-N2ExpTime-hardness for conjunctive query entailment in the description logic ALCOIF , thus improving the previously known 2ExpTime lower bound. The result transfers to ...
Abstract. Automata-based decision procedures commonly achieve optimal complexity bounds. However, in practice, they are often outperformed by sub-optimal (but more local-search bas...
