[目的 /意义]通过移动图书馆与非移动图书馆OPAC用户使用检索点的比较,探索用户通过不同设备使用图书馆OPAC系统的行为差异,为不同设备OPAC系统检索点的设置等提供参考。[方法/过程]运用日志挖掘法,对比分析移动图书馆与非移动图书馆检索点出现概率、检索点搜索成功率、检索点变化模式等方面的异同。[结果 /结论]移动图书馆与非移动图书馆检索点存在差异,非移动图书馆在检索点的设置和利用上具有优势。移动图书馆可以通过舍弃低概率的检索点,简化界面内容;通过设置网页标签的形式,方便用户转移检索点;通过减少组配的检索点数量,并突出检索点和检索框来提高组配检索的比例。
[Purpose / Significance] By comparing the use of search points between OPAC users in mobile libraries and non-mobile libraries, this paper explores the behavior differences of users using OPAC systems in different libraries and provides references for setting OPAC system search points of different devices. [Methods / Procedures] Using log mining method, the similarities and differences between the search probability of search points in mobile libraries and non-mobile libraries, the search success rate of search points and the change patterns of search points are compared and analyzed. [Result / Conclusion] There are differences between the retrieval points of mobile libraries and non-mobile libraries. Non-mobile libraries have advantages in the setting and utilization of retrieval points. The mobile library can simplify the content of the interface by discarding the low-probable retrieval points, facilitate the user to transfer the retrieval points by setting the form of the webpage labels, improve the grouping retrieval by reducing the number of the matching retrieval points and highlighting the retrieval points and the retrieval box proportion.
