There are a number of frameworks for modelling argumentation in logic. They incorporate a formal representation of individual arguments and techniques for comparing conflicting a...
Local computation in join trees or acyclic hypertrees has been shown to be linked to a particular algebraic structure, called valuation algebra. There are many models of this alge...
Abstract. TBox reasoning in description logics is hard. For example, reasoning in SROIQ (i.e. OWL2-DL) is N2EXPTIME-complete; even with R, a fragment of SROIQ supporting ALC GCIs a...
We present a matrix characterization of logical validity in the multiplicative fragment of linear logic with exponentials. In the process we elaborate a methodology for proving mat...
