社群环境下的协同信息检索行为实验研究

An Experimental Study on Collaborative Information Seeking Behavior in Community Environment

【目的】探究社群类型和任务难度对协同信息检索行为的影响。【方法】基于模拟实验,采用问卷调查法、Web日志收集法和访谈法采集数据,使用统计分析法和内容分析法分析数据。【结果】社群类型方面,社群比非社群在协同信息检索中有更多的推荐行为;在检索式构造上不依赖于检索系统;协作方式更为多样化;对任务相关知识的认知方面具有明显优势。但是,专业社群与兴趣社群之间几乎在任何方面都没有显著差异。任务难度差异仅体现在直接输入检索式的方式上,对是否能完成任务的信心具有较大影响。【局限】实验研究的是现实社群,还应加强对虚拟社群以及其他类型社群的研究。【结论】社群类型和任务难度对协同信息检索行为在不同方面产生了不同程度的影响,社群因素的影响比任务因素的影响大。社群与非社群的协同信息检索行为差异较大,但专业社群与兴趣社群则差异不显著。

[Objective] This paper aims to explore how the community type and task difficulty influence the collaborative information seeking behavior. [Methods] Data collection methods include questionnaires, Web log analysis and semi-structured interview. Data analysis methods include statistical analysis and content analysis. [Results] In terms of the community type, compared with non-community, the community has more behaviors of Recommend, it does not depend on the retrieval system when inputting queries, its collaborative approaches are more diverse, it has advantages on the awareness of task knowledge. However, the profession community has no obvious differences with the interest community on any aspect. In terms of the task difficulty, it only influences the methods of issuing queries and confidence of completing the tasks. [Limitations] This paper researches on the real community. It should investigate virtual community and more types of communities in the future. [Conclusions] The community type and task difficulty have different degrees of influence on the different aspects of collaborative information seeking behavior. The factor of community has more influences than the factor of task. And the differences between the community and non-community are obvious, however, the differences between the profession community and the interest community are not significant.
