摘要
[目的/意义]"搜索即学习"是近年来交互式信息检索的研究热点,用户在学习型搜索任务下的交互特征是优化学习型搜索系统的基础,认知风格与话题熟悉度作为用户重要的个人知识特征,值得深入研究。[方法/过程]文章采用用户实验法,将用户完成学习型任务的交互行为划分为搜索、阅读和记录三类,探索认知风格与话题熟悉度如何分别及共同影响这些交互行为。数据分析阶段采用双因素方差分析方法。[结果/结论]研究发现,认知风格主要影响用户在学习型搜索任务下的搜索行为,话题熟悉程度影响阅读行为和记录行为;此外,两者对用户的搜索结果利用率和平均记录时间等交互行为产生交互影响,而不同用户在各类交互行为的时间分配上具有一致性。
