Aspects of semantic interpretation, such as quantifier scoping and reference resolution, are often realised computationally by non-monotonic operations involving loss of informati...
Vulnerabilities in a system may have widely varying impacts on system security. In practice, security should not be defined as the absence of vulnerabilities. In practice, securit...

One of Semantic Web strengths is the ability to address incomplete knowledge. However, at present, it cannot handle incomplete knowledge directly. Also, it cannot handle non-monoto...
Craig's Interpolation Theorem is an important meta-theoretical result for several logics. Here we describe a formalisation of the result for first-order intuitionistic logic w...
Logic programming with negation offers a compelling approach to abductive reasoning. This paper shows a simple view of abduction in this context for the completion semantics, unde...
