Abstract

In this paper, we discuss the draft OWL 2 RL profile from the perspective of applying the constituent rules over Web data. In particular, borrowing from previous work, we discuss (i) optimisations based on a separation of terminological data from assertional data and (ii) the application of authoritative analysis to constrain third party interference with popular ontology terms. We also provide discussion relating to the applicability of new OWL 2 constructs for two popular Semantic Web ontologies --- namely FOAF and SIOC --- and provide some evaluation of the proposed use-cases based on reasoning over a representative Web dataset of approx. 12 million statements.
