Overviewing the RDF(S) semantic web

Abstract—The RDF(S) semantic web consists of many billions statements about resources (RDF data and RDFS metadata). We propose an original and effective approach to improve performance of retrieving information in RDF(S) statements sets, by quickly discarding irrelevant RDF data sets and moreover using classic search ways (like SPARQL and Jena). To that end, we define and associate at each RDF data set a kind of overview, small and search-oriented, which has to be queried first before querying whole data. Index Terms—semantic web; RDF(S); overviewing informa-tion; compression by specialization; web search; large scaling I
