What's in a model? Epistemological analysis of Logic Programming
It is commonly believed that the meaning of a formal declarative knowledge representation language is determined by its formal semantics. This is not quite so. This paper shows an...

Solving Hard Disjunctive Logic Programs Faster (Sometimes)
Disjunctive Logic Programming (DLP) under the consistent answer set semantics is an advanced formalism for knowledge representation and reasoning. It is, under widely believed assu...

Ordered Programs as Abductive Systems
In ordered logic programs, i.e. partially ordered sets of clauses where smaller rules carry more preference, inconsistencies, which appear as conflicts between applicable rules, a...

Transforming co-NP Checks to Answer Set Computation by Meta-Interpretation
Many NP-complete problems can be encoded in the answer set semantics of logic programs in a very concise way, where the encoding reflects the typical “guess and check” nature ...

Local Closed-World Assumptions for reasoning about Semantic Web data
Abstract The Semantic Web (SW) can be seen as abstract representation and exchange of data and metadata. Metadata is given in terms of data mark-up and reference to shared, Web-acc...

An Ordered Choice Logic Programming Front-End for Answer Set Solvers
Abstract. Ordered Choice Logic Programming (OCLP) allows for preferencebased decision-making with multiple alternatives without the burden of any form of negation. This complete ab...
