| Abstract(in English) | The number and size of RDF graphs on the Web grow continuously and demand efficient solutions with compressed data storage and fast search. However, fast search is achieved by adding index structures, so it isimportant to reduce both the search time and the memory space. In this work, we propose a Relay Index with only a dual data structure and a query plan algorithm based on a Variable Chain with no additional data. A comparative experiment with TENTRIS, known as a fast RDF store, shows that the search time does not increase and the memory usage is morethan 20 times effective. |
