Magic Computation for Wll-founded Semantics
We propose a new realization of goal-directed query evaluation of (non-oundering) normal logic programs for the well-founded semantics. To this end we introduce a new magic templates transformation and give a new xed point characterization of the well-founded semantics, lifting an existing deenition from the ground to the non-ground case. The new xed point characterization enables us to show a ...
متن کاملBusiness Semantics: The Magic Instrument Enabling Plug & Play Collaboration?
Business is changing towards knowledge intensive and value critical over the life cycle. Products are increasingly embedding intelligence; therefore the role of Service and Product Architecture is becoming very important. In the context of knowledge sharing we use the term ontology to mean a specification of a conceptualization. That is, ontology is a description [like a formal specification of...
متن کاملMinstrel Reloaded: From the Magic of Lisp to the Formal Semantics of OWL
This paper is a review of a story generation system called Minstrel. It uses complex but hand-crafted Lisp knowledge structures to generate short computer-generated stories within the King Arthur domain. The knowledge representation model of Minstrel is reimplemented using a W3C standard language to analyze the pros and cons of technology updates over this kind of classic AI projects.
متن کاملA \varGamma -magic Rectangle Set and Group Distance Magic Labeling
A Γ -magic rectangle set MRSΓ (a, b; c) of order abc is a collection of c arrays (a× b) whose entries are elements of group Γ , each appearing once, with all row sums in every rectangle equal to a constant ω ∈ Γ and all column sums in every rectangle equal to a constant δ ∈ Γ . In the paper we show that if a and b are both even then MRSΓ (a, b; c) exists for any Abelian group Γ of order abc. Fu...
متن کاملCreating Semi-Magic, Magic and Extra Magic n× n Squares when n is Odd
We define a simple algorithm for creating large numbers of semi-magic n× n squares when n is odd. Special cases of the algorithm can also be used to easily create magic and extra magic (or panmagic) n× n squares when n is odd. The algorithm can also create extremely magic n × n squares when n ≥ 5 is prime. These extremely magic n × n squares have n! standard magic n-element subsets, and these n...
