Journal ArticleDOI
Declarative modeling of the operational behavior of logic languages
TL;DR: A new declarative semantics for logic programs is defined, which is based on interpretations containing (possibly) non-ground atoms, and one of the two models allows the set of computed answer substitutions to be characterized precisely.
Journal ArticleDOI
The s-semantics approach: Theory and applications
TL;DR: In this paper, an approach to the semantics of logic programs whose aim is to find notions of models which really capture the operational semantics, and are, therefore, useful for defining program equivalences and for semantics-based program analysis is presented.
Journal ArticleDOI
Kernel-LEAF: a logic plus functional language
TL;DR: Kernel-LEAF is a logic plus functional language based on the flattening technique that is able to cope with partial functions and has a clean model-theoretic semantics, where the domains of the interpretations are the algebraic CPOs.
Journal ArticleDOI
A grey-weighted skeleton
Giorgio Levi,Ugo Montanari +1 more
TL;DR: In this paper a grey-weighted skeleton is defined for grey-valued continuous and quantized images, and a procedure for the inversion of agrey-weighting skeleton is proposed for obtaining a binary reconstructed image from aGrey-Weighted skeleton.
Journal ArticleDOI
A general framework for semantics-based bottom-up abstract interpretation of logic programs
TL;DR: This paper defines an abstract interpretation framework based on a fixpoint approach to the semantics which leads to the definition, by means of a suitable set of operators, of an abstract fixpoint characterization of a model associated with the program.
