Abstract. In this paper, we continue the recently started work on integrating action formalisms with description logics (DLs), by investigating planning in the context of DLs. We p...
The purpose of validating a conceptual schema is to check whether it specifies what the designer intended. Our approach to validation consists in translating the schema into logic ...
Abstract. In this paper, we propose more flexible applicability conditions for the folding rule that increase the power of existing unfold/fold systems for normal logic programs. O...
This paper proposes constructs that can be used to declaratively specify the disjoint nature of object properties or roles. These constructs may be a useful extension to the Descr...
Transitive roles are important for adequate representation of knowledge in a range of applications. In this paper we present a first algorithm to compute least common subsumers i...
