Transitive roles are important for adequate representation of knowledge in a range of applications. In this paper we present a first algorithm to compute least common subsumers i...
This paper presents a new Lambda-Boolean reduction machine for Lambda-Boolean and Lambda-Beta Boolean reductions in the context of Lambda Calculus and introduces the role of Churc...
Logic and probability theory have both a long history in science. They are mainly rooted in philosophy and mathematics, but are nowadays important tools in many other fields such...
We show that a logical framework, based around a fragment of existential second-order logic formerly proposed by others so as to capture the class of polynomially-bounded P-optimi...
This paper studies the relationship between logic programs and term rewriting systems (TRSs). A compositional transform is de ned which given a logic program computes a TRS. For a...
