A justification for an entailment in an OWL ontology is a minimal subset of the ontology that is sufficient for that entailment to hold. Since justifications respect the syntactic form of axioms in an ontology, they are usually neither syntactically nor semantically minimal. This paper presents two ...

In this paper, we present an approach to determining the cognitive complexity of justifications for entailments of OWL ontologies. We introduce a simple cognitive complexity model and present the results of validating that model via experiments involving OWL users. The validation is based on test da ...

In this paper, we present the new version of WebProtégé that we designed with two m ...

The Atomic Decomposition of an ontology is a succinct representation of the logic-based modules in that ontology. Ultimately, it reveals the modular structure of the ontology. Atomic Decompositions appear to be useful for both user and non-user facing services. For example, they can be used for onto ...

We will provide a brief introduction to OWL, in fact OWL2, and the underlying Description Logic, clarifying the semantics and providing examples to help the understanding of this admittedly complex formalism. In particular, we will discuss common misunderstandings around OWL and OWL2, explain the op ...
