Jingwei+: A distributed large-scale RDF data server

Abstract

With the development of the Linked Data project, the amount of RDF data published on the Web is steadily growing. To deal with the management issues of large-scale RDF data efficiently, we have developed a Bigtable-based distributed RDF repository, named Jingwei+, with a high level of scalability, to support the fast execution of triple pattern queries. The data service engine of Jingwei+ provides RESTful API to the outside, and its Web user interface have implemented the triple pattern query and the Linked Data navigational browsing. This paper demonstrates the query and navigation features of Jingwei+. The Jingwei+ RDF data server has laid the foundation of further development of the Semantic Web search engine. © 2012 Springer-Verlag Berlin Heidelberg.
