摘　　要：信息搜索用户的学习交互是包含用户-搜索系统交互、用户-搜索引擎结果页面交互、用户-搜索内容交互、用户-其他用户交互等维度的综合概念体系。协同搜索情境则进一步增加了用户学习交互的复杂性。文章设计一项信息搜索实验,以探究不同社交关系类型和协作效能水平对协同搜索用户学习交互的影响,为理解信息搜索用户的协作学习机制奠定基础;使用双因素方差分析法、Mann-Whitney U非参数检验与质性分析法,综合分析实验当中产生的数据。研究发现:社交关系类型不能对协同搜索用户的学习交互产生影响;协作效能对协同搜索用户的网页链接深度、知识讨论次数和知识共享次数具有主效应;社交关系类型与协作效能对用户的网页平均浏览时间具有交互作用:高协作效能水平下,朋友组的网页平均浏览时间多于陌生人组,低协作效能水平下,陌生人组的网页平均浏览时间多于朋友组。相关研究结论能够激励信息搜索用户对协作学习的重视,并为支持良好学习体验的协作信息检索系统的设计提供借鉴。Learning interaction during the information retrieval process is an integral concept,including the interactions between user and search system(U-S),search engine result page(U-SERP),search content(U-C),other users(U-U),and so on.Collaborative search further increases the complexity of the learning interaction.This paper designs an information search experiment to explore the effects of social relationships and collaborative efficiency(or,collaborative effectiveness) on users' learning interaction,thus laying a foundation for understanding users' collaborative learning mechanism.Using two-factor ANOVA,Mann-Whitney U nonparametric tests and qualitative analysis,this paper comprehensively analyses the data generated in the experiment.The study shows:Social relationship type does not affect the learning interaction in collaborative search;Collaborative effectiveness has a main effect on the depth of web links,the number of knowledge discussions,and the amount of knowledge sharing among users;Social relationship type and collaborative effectiveness have an interaction effect on the average browsing time of users.The average browsing time of the friend group is higher than that of the stranger group at the high level of collaborative effectiveness,while the average browsing time of the stranger group is higher than that of the friend group at the low level of collaborative effectiveness.The study can encourage information seeking users to attach importance to collaborative learning,and serve as a reference for designing collaborative information retrieval systems to support better learning experience.
