Temporalising Tractable Description Logics
It is known that for temporal languages, such as firstorder LT L, reasoning about constant (time-independent) relations is almost always undecidable. This applies to temporal des...

Tractable Reasoning with DL-Programs over Datalog-rewritable Description Logics
Abstract. The deployment of KR formalisms to the Web has created the need for formalisms that combine heterogeneous knowledge bases. Nonmonotonic dl-programs provide a loose integr...
