The linked data benchmark council (LDBC)

In the last years we have seen an explosion of massive amounts of graph shaped data coming from a variery of applications that are related to social networks (Facebook, Twitter, blogs and other on-line media) and telecommunication networks. Furthermore, the W3C Linking Open Data Initiative [8] has boosted the publication and interlinkage of a large number of datasets on the Semantic Web [2] resulting to the Linked Open Data Cloud. These datasets with billions of RDF triples such as Wikipedia [5], US Census bureau [4], CIA World Factbook [1], DBPedia [5], and government sites1 have been created and published online. Moreover, numerous datasets and vocabularies from e-science are published nowadays as RDF graphs most notably in life and earth sciences, astronomy [6][7][3] in order to facilitate community annotation and interlinkage of both scientific and scholarly data of interest. Technology and bandwidth now provide the opportunities for compiling, publishing and sharing massive Linked Data datasets. A significant number of commercial semantic repositories (ie, RDF databases with reasoner and query-engine) which are the cornerstone of the Semantic Web exist.
