摘要
日常生活中,上网重复查询相关资源等情况十分普遍,但由于网络信息一直处于变化之中,信息重复检索结果可能存在差异。通过实验方法针对网络信息检索与再检索这两阶段对应的过程特性进行研究。研究结果显示,与初始检索过程对比来说,虽然信息重复检索相对比较节约时间,但其检索对应难度也比较高。最后,针对网络信息检索系统及个人信息管理层面提出一些改善建议。
In daily life,it is quite common to re-query related resources.However,the re-finding results of information may differ from each other due to the constant variation of web information.We mainly study the process characteristics corresponding to two phases of web information finding and re-finding by the means of experiment.Research result demonstrates that,compared with the initial finding process,though the information re-finding relatively saves more time,but the corresponding difficulty in finding is higher.In end of the paper,we present some improvement advices on web information retrieval system and personal information management issues.
