ABSTRACT
In this paper, we present a novel approach to compact the representation, called Combined Bit Map (CBM), which compresses the RDF data and allows the search for the specific terms using Graphics Processing Units (GPUs). Since GPUs have limited memory size, using the CBM structure enables us to put more RDF data in the GPU memory. Further, since GPUs contain many processing elements, utilizing them concurrently will speed up the RDF query processing. The experimental results show that the proposed representation can reduce the size of original RDF data by 70 percent. Furthermore, the search time on such a representation using the GPU is 60 times faster compared to the conventional search time.
