摘要：
In order to prefetch the data that may be accessed by user before a query was posed, a novel prefetching method towards databaspace by exploiting query logs was proposed. Firstly, some intention features were extracted from the query logs, and the clustering technique was performed on the intention features. Secondly, the user query intention was identified. Finally, the query answers were prefetched according to the identified intention. The experimental results show that the proposed method can not only have a higher accuracy, but also improve the query efficiency, and it outperforms the existing methods. © 2016, Editorial Board of Journal of Harbin Engineering.
