The Resource Description Framework (RDF) serves as the foundation for the publication of a growing amount of semantic web data still largely untapped by companies for data analysis. Most RDF data sources, however, do not correspond to the MD modeling paradigm and, as a consequence, elude traditional OLAP. The complexity of RDF data in terms of structure, semantics, and query languages renders RDF data analysis challenging for a typical analyst not familiar with the underlying data model or the SPARQL query language. Hence, conducting RDF data analysis is not a straightforward task. We propose an approach for the definition of superimposed MD schemas over arbitrary RDF datasets and show how to represent the superimposed MD schemas using well-known semantic web technologies. 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. Upon pattern instantiation, the corresponding SPARQL query over the source data can be automatically generated, sparing analysts from technical details and fostering self-service capabilities.<\/jats:p>","DOI":"10.1515\/comp-2018-0003","type":"journal-article","created":{"date-parts":[[2018,7,13]],"date-time":"2018-07-13T01:30:57Z","timestamp":1531445457000},"page":"18-37","source":"Crossref","is-referenced-by-count":4,"title":["Using superimposed multidimensional schemas and OLAP patterns for RDF data analysis"],"prefix":"10.1515","volume":"8","author":[{"given":"Median","family":"Hilal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph G.","family":"Schuetz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Schrefl","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","reference":[{"key":"ref111","first-page":"1","article-title":"Query Recommendation https www org sparql query","volume":"12","author":"SPARQL","year":"2013","journal-title":"Language"},{"key":"ref51","first-page":"905","article-title":"Vocabulary for OLAP cubes on the semantic web In Proceedings of COLD org","author":"Etcheverry","year":"2012"},{"key":"ref41","doi-asserted-by":"crossref","first-page":"151","DOI":"10.1007\/s12599-016-0424-6","article-title":"Self service","author":"Alpar","year":"2016","journal-title":"business intelligence Business Information Systems Engineering"},{"key":"ref121","first-page":"1","article-title":"Linked Data -
