We define a new operation in description logics, the difference operation or subtraction operation. This operation allows to remove from a description as much as possible of the i...
The paper presents experimental comparison of several resolution strategies for reasoning in Fuzzy Description Logic based on Fuzzy Predicate Logic with evaluated syntax. Resoluti...
We describe a method for characterizing the expressive power of description logics. The method is essentially model-theoretic in nature, and it is applied to obtain expressiveness...
Abstract. Nested logic programs and epistemic logic programs are two important extensions of answer set programming. However, the relationship between these two formalisms is rarel...
Permissive-Nominal Logic (PNL) is an extension of firstorder logic where term-formers can bind names in their arguments. This allows for direct axiomatisations with binders, such...
