It is widely accepted that spatial reasoning plays a central role in artificial intelligence, for it has a wide variety of potential applications, e.g., in robotics, geographical...

We show how edge-labelled graphs can be used to represent first-order logic formulae. This gives rise to recursively nested structures, in which each level of nesting corresponds ...
Defeasible Logic is a rule-based non-monotonic logic with tractable reasoning services. In this paper we extend Defeasible Logic with nested rules. We consider a new Defeasible Log...
Design constraints express essential behavioural properties of a software system. Two key elements of a scheme for enforcing design constraints are presented: a logic for describin...
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...
