To ensure the re-use of domain ontologies the usual approach relies on a pivot language, e.g., Kif, intoandfromwhich the domainontologyis translated. This requires several distinc...
This paper examines a new technique based on tableau, that allows one to introduce composition of roles from the right hand side of complex role inclusion axioms (RIAs). Our motiva...
We propose to build an automated reasoning system for first-order logic (FOL) by translating reasoning problems to a fragment of FOL called coherent logic (CL) and then solving t...
Unsatisfiable concepts are a major cause for inconsistencies in Description Logics knowledge bases. Popular methods for repairing such concepts aim to remove or rewrite axioms to r...
This paper proposes a framework to learn concepts from di erent kinds of observations. We de ne a language to describe meta-concepts, that represent the sets of possible concepts ...
