The original semantics of Evaluation Logic in [Mog93] relies on additional properties of strong monads. This paper extends the original semantics by dropping all additional requir...
In this paper we develop a generic declarative diagnoser for normal logic programs that is based on tree search. The soundness and the completeness of the diagnoser are proved. The...
Fixpoint expressions built from functional signatures interpreted over arbitrary complete lattices are considered. A generic notionof automatonis defined and shown, by means of a ...
Many visualization frameworks for ontologies in general and for concept expressions in particular are too faithful to the syntax of the languages in which those objects are represe...
We present lower bounds on the computational complexity of satisfiability and subsumption in several description logics. We interpret these lower bounds as coming from different...
