RDF Data Clustering.

The Web is evolving from a Web of Documents to a Web of Data. Meanwhile, the development of Semantic Web applications opens the way for addressing complex information needs. In this scenario, clustering is identified as a crucial task for semantic mashups. After a thorough review of RDF clustering techniques, the paper addresses the open issues within the efficient exploitation of the knowledge contained in RDF data sources. Then, first promising attempts in exploring the applicability of community detection algorithms for RDF clustering are reported.
