摘要
目前我国图书馆正在朝着数字化、多样化的方向发展。针对传统的图书馆图书信息采集方法存在的采集时间长、效率低等问题,提出一种柔性策略的图书信息自动采集方法。方法根据四象限划分方法划分数字图书馆图书信息,确定图书信息采集优先集,采用双重判断方法以单位时间内的图书信息变化量为依据,判断图书信息波动程度,并根据波动情况制定应激式调整方案,自适应调节采集间隔,完成图书信息自动采集。实验结果证明,所提方法可以快速、精确地完成图书信息采集。
At present,traditional book information collection methods lead to long collection time and low efficien-cy.Therefore,a method to automatically collect book information based on flexible strategy was proposed.The four-quadrant division method was used to divide the book information in digital library and determine the priority set of book information collection.Based on the change of book information in unit time,double judgment method was used to judge the fluctuation degree of book information.According to fluctuation situation,the stress adjustment scheme was made.The collection interval was adaptively adjusted.Finally,the automatic collection of book information was completed.Simulation results show that the proposed method can complete the collection of book information quickly and accurately.
