An Interest-based P2P RDF Query Architecture, “CNDS lab

Abstract. Currently most centralized RDF storage and query architecture have problems in query performance and scalability. In this paper we present a dis-tributed RDF query architecture to address these problems, which is built on Chord and Sesame. In our architecture, we construct semantic topology with distributed interest-index to route query and take advantage of semantic simi-larity between query and peer to select peers which are capable of answering the given query. Experimental results have showed that our approach has a much better performance while achieving a good recall rate.
