Abstract. In this paper we investigate the design space of access control logics. Specifically, we consider several possible axioms for the common operator says. Some of the axioms...
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...
Abstract. In this paper we investigate how to model legal abrogation and annulment in Defeasible Logic. We examine some options that embed in this setting, and similar rule-based s...
We propose undoable versions of the projection operations used when programs written in higher-order statically-typed languages interoperate with dynamically typed ones, localizing...
Abstract. In this paper, we propose more flexible applicability conditions for the folding rule that increase the power of existing unfold/fold systems for normal logic programs. O...
