We define logical relations between the denotational semantics of a simply typed functional language with recursion and the operational behaviour of low-level programs in a varian...
Abstract. A generalized decision logic in interval-set-valued information tables is introduced, which is an extension of decision logic studied by Pawlak. Each object in an interva...
In this paper, we propose a translation from normal first-order logic programs under the answer set semantics to first-order theories on finite structures. Specifically, we introd...
The use of background knowledge and the adoption of Horn clausal logic as a knowledge representation and reasoning framework are the distinguishing features of Inductive Logic Prog...
We outline a possible logic that will allow us to give a unified approach to reasoning about computational effects. The logic is given by extending Moggi’s computational λ-cal...
