Business Model Ontologies in OLAP Cubes [chapter]

Christoph Schütz, Bernd Neumayr, Michael Schrefl
2013 Lecture Notes in Computer Science  
We adopt business model ontologies for the representation of nonnumeric measures in OLAP cubes. We propose modeling guidelines and adapt traditional OLAP operations for ontologyvalued measures.  ...  Business model ontologies capture the complex interdependencies between business objects.  ...  OLAP with Ontology-valued Measures: Merge Abstraction replaces sets of RDF triples by more 'abstract' RDF triples. Shared facts represent additional background knowledge about a business domain.  ...

Transforming multidimensional models into OWL-DL ontologies

Nicolas Prat, Jacky Akoka, Isabelle Comyn-Wattiau
2012 2012 Sixth International Conference on Research Challenges in Information Science (RCIS)  
Based on this model, OLAP cubes may be defined, enabling decision makers to analyze and synthesize data. Ontologies (and, more specifically, OWL ontologies) are a key component of the semantic Web.  ...  The ontology may also be used to represent OLAP cubes on the semantic Web (with RDF), by defining these cubes as instances of the OWL-DL multidimensional ontology.  ...  It is therefore natural to combine business intelligence (and more specifically multidimensional modeling and OLAP) with the semantic Web (more specifically ontologies).  ...
