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 ...
We show how the reasoning tasks of checking various versions of conservativity for the description logic DL-Litebool can be reduced to satisfiability of quantified Boolean formulas...

The paper addresses the problem of explaining some reasoning tasks associated with the DL-Lite Description Logic. Because of the simplicity of the language, standard concept level ...

Many visualization frameworks for ontologies in general and for concept expressions in particular are too faithful to the syntax of the languages in which those objects are represe...
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 show that reasoning in the temporal conceptual model ERV T , a fragment of ERV T that only allows timestamping is complete for 2-ExpTime. The membership result is based on an em...
Description Logics are a family of very expressive logics but some forms of knowledge are much more intuitive to formulate otherwise, say, as rules. Rules in DL can be dealt with t...
