| Abstract: |
| With the advance of the semantic Web and information extraction techniques, more and more RDF data emerge on the Web. Managing massive RDF data has been a hot research topic for both academic and industrial communities. In the paper, we give a thorough analysis and comparison of the existing techniques from the view of the accumulation and organization of RDF data. Topics on query representation, query processing and query optimization are extensively discussed. We finally identify challenges and future work of the area. |
