Using superimposed multidimensional schemas and OLAP patterns for RDF data analysis

Median Hilal, Christoph G. Schuetz, Michael Schrefl
2018 Open Computer Science  
On top of that, we introduce OLAP patterns for RDF data analysis, which are recurring, domain-independent elements of data analysis.  ...  Analysts may compose queries by instantiating a pattern using only the MD concepts and business terms.  ...  Analysts may then instantiate OLAP patterns by providing elements from an MD schema and business terms as actual values for the formal pattern elements.  ...
