“…For the Semantic Web to work, both triple-stores and SPARQL query processing engines have to scale well with the size of data. This is especially true when the size of RDF data is too big such that it is difficult, if not impossible, for conventional triple-stores to work with (Cudré-Mauroux et al, 2013;Luo, Picalausa, Fletcher, Hidders, & Vansummeren, 2012;Wilkinson, Sayers, Kuno, Reynolds, & others, 2003) In the past few years, however, new advances have been made in the processing of large volumes of data sets, aka big data, which can be used for processing big RDF data (Abadi, Marcus, Madden, & Hollenbach, 2007;Morsey, Lehmann, Auer, & Ngomo, 2011;Sakr & AlNaymat, 2010).…”
