An Attributed Predicate RDF

In knowledge representation reification, N-Quads and Named Graph have been introduced to represent context of knowledge, meta-information, provenance or any statements of statement. In this work we propose an attributed predicate RDF as a new alternative model in triple RDF to overcome the problem to represent statements of statement or any additional information of statement. We study that the predicate of RDF will play a more important role in graphs of knowledge. We can add any statements of statement by connecting them to the predicate. Basically, therefore we extend the predicate of RDF accordingly. The result of this work show that our model can avoid reification, adding context and any additional statements to enrich the main statement in triple RDF. Finally, it can be retrieved naturally by SPARQL. The experimental result shows that the performance of our model surpasses the performances of the other models.
