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,Web资源二次查询与一般一次查询结果可能存在差异.主要通过实验方法针对Web资源二次查询检索行为特性进行分析与研究.研究结果显示,相对比于信息一次查询行为,在Web资源二次查询过程中所使用的检索方式、检索策略更为多元化、所采用的检索优化方法更丰富.为搜索引擎技术的发展进行了信息检索角度的有益探讨.%It is very common in daily life to access the internet for querying the related resources repeatedly. However, usually the result of the secondary query on Web resources may differ to the one from the first query due to constant variation of networks information. In this paper, we analyse and study mainly through the means of experiments the behaviour characteristics of secondary Web resource query and retrieval. Study result shows that, compared with the first information query behaviour, the retrieval means and strategies used in secondary Web resources querying process are more diversified, the retrieval optimisation approach used has more choices. This article made a useful discussion on the development of search engine technology in terms of information retrieval perspective.
