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...
The paper proposes a formal analysis of the ascriptive view of norms as resulting from pulling together Anderson's reductionist approach, the analysis of counts-as, and a nove...
The verification problem for action logic programs with non-terminating behaviour is in general undecidable. In this paper, we consider a restricted setting in which the problem be...
This paper presents a first step towards a security model that defines access control for logical document structures. el benefits from roles to abstract from users and from secur...
We study the effect of information overload on user engagement in an asymmetric social network like Twitter. We introduce simple game-theoretic models that capture rate competition...
