The DMCS Solver for Distributed Nonmonotonic Multi-Context Systems
The DMCS system is an implementation of the equilibrium semantics for heterogeneous and nonmonotonic multi-context systems (MCS) [3], which feature contexts with heterogeneous and possibly nonmonotonic logics. Ea...

Decomposition of Distributed Nonmonotonic Multi-Context Systems
Multi-Context Systems (MCS) are formalisms that enable the interlinkage of single knowledge bases, called contexts, via bridge rules. Recently, a fully distributed algorithm for evaluating heterogeneous, nonmo...

Realizing Default Logic over Description Logic Knowledge Bases
We consider a realization of Reiter-style default logic on top of description logic knowledge bases (DL-KBs). To this end, we present elegant transformations from default theories to conjunctive query (cq-)pro...

Relevance-Driven Evaluation of Modular Nonmonotonic Logic Programs
Modular nonmonotonic logic programs (MLPs) under the answer-set semantics have been recently introduced as an ASP formalism in which modules can receive context-dependent input from other modules, while allowi...
