Nonmonotonic Description Logic Programs: Implementation and Experiments
Abstract. The coupling of description logic reasoning systems with other reasoning formalisms (possibly over the Web) is becoming an important research issue and calls for advanced...

Nonmonotonic Model Inference-A Formalization of Student Modeling
A student model description language and its synthesis method are presented. The language called SMDL is based on a logic programming language taking 4 truth values such as true, ...

Exploiting Conjunctive Queries in Description Logic Programs
We present cq-programs, which enhance nonmonotonic description logics (dl-) programs by conjunctive queries (CQ) and union of conjunctive queries (UCQ) over Description Logics kno...

Nonmonotonic Ontological and Rule-Based Reasoning with Extended Conceptual Logic Programs
We present extended conceptual logic programs (ECLPs), for which reasoning is decidable and, moreover, can be reduced to finite answer set programming. ECLPs are useful to reason ...

Experimenting with Nonmonotonic Reasoning
In this paper, we describe a system, called TheoryBase, whose goal is to facilitate experimental studies of nonmonotonic reasoning systems. TheoryBase generates test default theor...
