A paraconsistent semantics with contradiction support detection

We begin by motivating the use of paraconsistency and the detection of contradiction supported conclusions by recourse to examples. Next we overview WFSX_P and present its embedding into WFS. We then address the problem of detecting contradiction support and relate it to WFSX_p's intrinsic properties. Afterwards, we show how to implement two recent modal contradiction related constructs in the language of extended logic programs in order to gain explicit control of contradiction propagation. We finish by making comparisons and drawing some conclusions.
