Abstract
Query requests for RDF triples are obtained, wherein the query request(s) contain(s) at least one triple pattern; for each triple pattern, the corresponding elementary pattern is determined, and each triple pattern is converted to a weighted elementary pattern. The occurrence frequency of each elementary pattern is computed based on the weighted elementary patterns; at least one elementary pattern is chosen at least according to the occurrence frequency; and the RDF triples corresponding to the chosen at least elementary pattern are prefetched into the buffer. The corresponding apparatus is also provided. With the above method and apparatus, the frequently accessed RDF triples can be determined and prefetched into the buffer, which improves the query efficiency.
