Two levels of description of nonmonotonic reasoning are distinguished. For these levels semantical formalizations are given. The first level is defined semantically by the notion o...
The CEL system is known for its scalability of reasoning in the lightweight DL EL++ which has been proved suitable for several ontology applications, most notably from the life sci...
Previous CASC competitions have focused on proving difficult problems on small numbers of axioms. However, typical reasoning applications for expert systems rely on knowledge base...

In this paper we develop frameworks for logical systems which are able to re ect not only nonmonotonic patterns of reasoning, but also paraconsistent reasoning. For this we conside...
Well Founded Semantics is adequate to capture nonmonotonic reasoning if we interpret the Well Founded model of a program P as a (possibly incomplete) view of the world. Thus the W...
