Representing Paraconsistent Reasoning via Quantified Propositional Logic,can be naturally formulated or reformulated by means of quantified Boolean formulas. More precisely, we describe polynomial-time constructible encodings providing axiomatisations of the given reasoning tasks. In this way, a whole variety of a priori distinct approaches to paraconsistent reasoning be

On the Complexity of Paraconsistent Inference Relations,ques have been investigated in depth from a logical point of view, but far less to what concerns the computational complexity aspects. The purpose of this chapter is to present in a structured way the main complexity results identified so far for paraconsistent inference based on multi-valued propositional logics.

Relevant Logic and Paraconsistency, then examined. The relevant refusal to validate these inferences is defended, and finally it is suggested that more needs to be done towards a satisfactory theory of when they may nonetheless safely be used.

Consistency of XML Specifications,on the classes of DTDs and constraints involved, it ranges from linear time to undecidable. Furthermore, we show that for some of the most common classes of specifications checking consistency is intractable.
