| 摘 要： | 把高频词及其可视化呈现作为数字图书馆用户信息分析的辅助策略，对其与用户信息分析效率之间的关系进行考察，通过对照两组用户三个阶段的实验结果，发现高频词表对被试完成浏览型的数字信息分析任务的效率无显著影响；高频词的可视化呈现对被试完成浏览型数字信息分析任务的效率有显著影响；高频词及其可视化呈现对被试完成归类型数字信息分析任务的效率无影响。实验结果证明了数字图书馆辅助用户提高信息分析效率的可行性。

| Abstract: | The paper provides high-frequency-word lists and their visualized figures as assist-tools,explores the relationship among the tools and the efficiency of users’ analysis of digital information.Through a pre-and post-test compared team design experiment,it finds that: high-frequency-word lists doesn’t affect users’ efficiency of digital information analysis significantly;the providing of visualized figures of high-frequency-words significant improves the efficiency of users’ information analysis;however,the tools doesn’t affect the efficiency of user’ information analysis in processing of classification tasks significantly.The experiment results show the feasibility of auxiliary-strategies of users’ digital information analysis. |
