Answering conjunctive queries (CQs) has been recognized as a key task for the usage of Description Logics (DLs) in a number of applications. The problem has been studied by many au...
Representing probabilistic knowledge in combination with a description logic has been a research topic for quite some time. In [1] one of such combinations is introduced. We presen...
A recurring problem in conceptual modelling and ontology development is the representation of part-whole relations, with a requirement to be able to distinguish between essential a...
We study conjunctive query answering in the description logic EL, the core of the designated OWL2-EL profile of OWL2. In particular, we present an approach that allows the use of c...
We present an empirical analysis of optimization techniques devised to speed up the so-called TBox classification supported by description logic systems which have to deal with ve...
