The paper investigates the characterisation of vague concepts within the framework of modal logic. This work builds on the supervaluation approach of Fine and exploits the idea of...
This paper proposes a modelling of information security policies in the framework of possibilistic logic. Our modelling is based on the concept of roles associated with users. Acc...
Abstract. Higher-order representation techniques allow elegant encodings of logics and programming languages in the logical framework LF, but unfortunately they are fundamentally i...
We present a framework for encoding planning problems in logic programs with negation as failure, having computational e ciency as our major consideration. In order to accomplish o...
In previous work, we developed a framework for expressing general preference information in default logic and logic programming. Here we show that the approach of Brewka and Eiter ...
