采用系统日志法、问卷调查法、半结构化访谈法等数据收集方法,以及统计分析法和内容分析法等数据分析方法在Coagmento系统上进行用户协同信息检索实验及结果分析。实验结果显示,协同能力和任务类型均对用户的协同信息检索行为产生影响:协同能力不同的用户在“推荐”行为上差异显著;任务类型不同对用户的“浏览网页”、“检索”和“使用图片”行为影响较大。且协同能力较强的用户在实验中获得更好的检索效果,因此,协同检索系统更适合由协同能力较强的用户通过合作来完成复杂任务。 Data collection methods such as system log method, questionnaire method and semi-structured interview method, as well as data analysis methods such as statistical analysis method and content analysis method were used to carry out user collaborative information retrieval experiment and result analysis on Coagmento system. The experimental results show that collaborative ability and task type all have an impact on users’ collaborative information retrieval behavior: users with different synergistic capabilities have significant differences in behavior of “recommending”; tasks of different types have different impacts on the user’s “Retrieve ” and “Use Image ” behavior are more influential. Therefore, the collaborative retrieval system is more suitable for users who have stronger collaborative ability to complete complex tasks through cooperation.
