Abstract. Van Emden and Kowalski proposed a fixpoint semantics based on model-theory and an operational semantics based on proof-theory for Horn logic programs.

In this thesis, we provide a departure from the framework of definite programs by extending the theoretical results of Horn programs to disjunctive (indefinite) ...
In this paper, we extend the semantics of extended Horn programs to disjunctive logic programs with classical negation. We call such programs as extended ...
Disjunctive logic programs are natural extensions of Horn logic programs to represent dis- ... well-founded semantics for general Horn logic programs. For ...
Denotational semantics of logic programming and its extensions (by allowing negation, disjunctions, or both) have been studied thoroughly for many years.

The minimal model semantics of Horn clauses is the basis for the stable model semantics of logic programs.
Abstract. The use of explicit negation enhances the expressive power of logic programs by providing a natural and unambiguous way to assert negated.
Abstract In this paper, it is shown that stable model semantics, perfect model semantics, and partial stable model semantics of disjunctive logic programs ...
