In this paper we extend the logic of violation proposed by [14] with time, more precisely, we temporalise that logic. The resulting system allows us to capture many subtleties of t...
We propose a computationally oriented non-monotonic multi-modal logic arising from the combination of agency, intention and obligation. We argue about the defeasible nature of thes...
In recent years, several researchers have proposed techniques for providing users with assistance in understanding and overcoming authorization denials. The incorporation of envir...

We describe our preliminary work in modeling conversation specifications and policies as positive/negative permissions and obligations. Our model is generic as it is independent o...
This paper introduces a technique for incremental and compositional model checking that allows efficient reuse of model-checking results associated with the features in a product l...
