SLGAD Resolution for Inference on Logic Programs with Annotated Disjunctions
Abstract. Logic Programs with Annotated Disjunctions (LPADs) allow to express probabilistic information in logic programming. The semantics of an LPAD is given in terms of the well...

A Note on the Relationships Between Logic Programs and Neural Networks
Several recent publications have exhibited relationships between the theories of logic programming and of neural networks. We consider a general approach to representing normal lo...

On Odd and Even Cycles in Normal Logic Programs
An odd cycle of a logic program is a simple cycle that has an odd number of negative edges in the dependency graph of the program. Similarly, an even cycle is one that has an even...

Beyond Tamaki-Sato Style Unfold/Fold Transformations for Normal Logic Programs
Unfold/fold transformation systems for logic programs have been extensively investigated. Existing unfold/fold transformation systems for normal logic programs allow only Tamaki-Sa...

Induction of Stable Models
In the line of previous work by S. Muggleton and C. Sakama, we extend the logical characterization of inductive logic programming, to normal logic programs under the stable models ...

Using Nested Logic Programs for Answer Set Programming
We present a general method to improve computation of answer sets by analyzing structural properties of normal logic programs. Therefore we use labeled directed graphs associated t...

Semantics of disjunctive programs with monotone aggregates - an operator-based approach
All major semantics of normal logic programs and normal logic programs with aggregates can be described as fixpoints of the one-step provability operator or of operators that can...

An Algorithm for Local Variable Elimination in Normal Logic Programs
A variable is local if it occurs in a clause body but not in its head. Local variables appear naturally in practical logic programming, but they complicate several aspects such as ...

A Purely Model-Theoretic Semantics for Disjunctive Logic Programs with Negation
Abstract. We present a purely model-theoretic semantics for disjunctive logic programs with negation, building on the infinite-valued approach recently introduced for normal logic...
