Abstract. We describe the key features of the proof description language of Declare, an experimental theorem prover for higher order logic. We take a somewhat radical approach to p...
We outline DLMedia, an ontology mediated multimedia information retrieval system, which combines logic-based retrieval with multimedia featurebased similarity retrieval. An ontolog...
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...
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...
