In the context of exploratory OLAP, coupling the information wealth of linked data with the precision and detail of corporate data can greatly improve the effectiveness of the decision-making process. In this paper we outline an approach that enables users to extend the hierarchies in their corporate cubes through a user-guided process that explores selected linked data and derives hierarchies from them. This is done by identifying in the linked data the recurring modeling patterns that express roll-up relationships between RDF concepts and translating them into multidimensional knowledge.

Abstract
In the context of exploratory OLAP, coupling the information wealth of linked data with the precision and detail of corporate data can greatly improve the effectiveness of the decision-making process. In this paper we outline an approach that enables users to extend the hierarchies in their corporate cubes through a user-guided process that explores selected linked data and derives hierarchies from them. This is done by identifying in the linked data the recurring modeling patterns that express roll-up relationships between RDF concepts and translating them into multidimensional knowledge.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
