[目的 /意义]探讨高校图书馆用户在使用图书馆OPAC系统查找相关资源时调整提问的行为模式。[方法/过程]以北京师范大学图书馆OPAC日志数据为对象,采用S.Y.Rieh与Xie Hong提出的提问调整模式类型,利用内容分析法对提问日志进行内容编码和统计分析。[结果 /结论]高校图书馆用户的OPAC提问调整基本模式与网络信息检索提问调整模式基本一致,并且,在动态调整模式过程中,还可以细化为直线、阶梯、锯齿、凹凸、循环等子模式。针对如何优化OPAC系统和提升用户信息素养提出若干建议。
[Purpose / Significance] To explore the behavioral mode of university library users adjusting questions when they use the library OPAC system to find related resources. [Method / Process] Taking the OPAC diary data of Beijing Normal University Library as an object, this paper adopts the questions raised by S.Y.Rieh and Xie Hong to adjust the pattern types, and uses the content analysis method to carry out content coding and statistical analysis on the question log. [Result / Conclusion] The basic mode of OPAC question adjustment of university library users is basically consistent with that of online information retrieval and questioning, and can be further subdivided into straight lines, steps, serrations, concavities and convexities, loops, etc. during the dynamic adjustment mode mode. Suggestions on how to optimize OPAC system and improve user information literacy.
