针对分布式搜索引擎系统中页面信息分布与动态迁移问题,提出了一种信息的动态迁移算法,并对算法参数进行了实验确定。该算法充分利用用户反馈,使得页面信息在各个站点间达到近似最优的分布。经模拟验证,该算法可以有效地优化信息分布、改善系统性能。
Aiming at the distribution and dynamic migration of page information in distributed search engine system, a dynamic information migration algorithm is proposed and the algorithm parameters are experimentally determined. The algorithm makes full use of user feedback, so that the page information reaches an approximately optimal distribution among all the sites. The simulation results show that the algorithm can effectively optimize the information distribution and improve the system performance.
