Research on the Improved Storage and NSDL ScheduIing AIgorithm Based on Top-k Query AIgorithms
Top-k query algorithms for its high efficiency has been widely applied, but its efficiency with the increase in size of data, shows a larger decline. Aiming at the Top-k query algorithms defects, puts a NSDL scheduling algorithm based on disk storage, and the NSDL algo-rithms for Top-k query algorithms that approximate, ANSDL. Compares NSDL and traditional I/O overhead DG algorithm, judges from the results, NSDL algorithms with higher efficiency and precision, and ANSDL algorithms under certain conditions to further improve the NS-DL query efficiency.
