Design And Implementation Of RDF Graph Management Tool

Semantic Web is referred as the next generation of Web technologies, RDF is a standard framework for the Semantic Web, it has formed a multi-layered Semantic Web architecture with RDF. SPARQL is a query language and protocol designed by the W3C RDF Data Working Group, it can query for RDF data. The RDF graph management command of SPRAQL can create, remove a graph and also allows move, copy, add operation between graphs.the Add command,which is a RDF graph management command, execute the merge processing when RDF triples are different. It consider two RDF triples are completely different as long as there is any literally difference in the subject, predicate or object. But actually, different descriptions of the same resource may be semantically identical or similar, the Add operation is to make the same semantic RDF triples to a graph if only rely on the literally identification,this operation will undoubtedly increase the redundant data in RDF graph.this paper propose a RDF triples-similar assessment programs which based on WordNet, and propose a new RDF graph management command "SimiAdd". The simiAdd command no longer checked if the RDF triples are literally identical, but check the RDF triples’s semantic similarity,only RDF triples that have little semantic similarity will have to do a merge operation.Contrast the result of the execution of Add command and SimiAdd command, the SimiAdd command which is based on the RDF triples-similarity assessment program can effectively filter out some semantic similar triples when operating RDF graph merge process, to some extent, it can avoid too much redundant set of RDF graph, and it make the RDF graph management more convenient.
