Abstract

In this paper we focus on providing a cache model based on Top-K data source instead of expatiatory result records for deep web query. By integrating techniques from IR and Top-K, a data reorganization strategy is presented. Also some measures about cache management and optimization are proposed to improve the performances of cache effectively. Results from the simulation show the proposed cache model significantly improves query performance when compared with various alternate strategies.
