协同信息检索行为中的认知研究

A Study of Awareness in Collaborative Information Seeking Behaviors

本文采用问卷调查法和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系统上进行了用户协同信息检索实验，旨在考察协同能力和任务类型这两个因素对协同信息检索行为的情境认知、任务认知和协同认知的影响。实验结果显示，协同能力强弱对用户的情境认知和协同认知的影响较大，而任务类型不同对用户的任务认知影响较大。协同方式从横向上可分为按内容、角色或二者结合分工；从纵向上可分为动态或静态分工。信息类任务分工最为明确，最适合用协同检索系统来完成；事务类任务分工较难，最不适合用协同检索系统来完成。

In order to investigate the impacts of collaborative abilities and task types on people＇s context awareness, task awareness, and collaboration awareness in collaborative information seeking behaviors, we conducted a collaborative information search experiment using the Coagmento system. We also used semi-structured interview and questionnaires for data collection, and content analysis as well as statistical testing as the data analysis methods. Our results show that collaborative abilities have much greater influence on context awareness and collaboration awareness, whereas task types have much greater influence on task awareness. In addition, we find that users＇ collaboration strategies can be divided into content-based mission assignment, role-based mission assignment, and content-role combined mission assignment from the horizontal angle, and dynamic strategy and static strategy from the vertical angle. Since informational tasks are easy to be divided and assigned separately, they are the most suitable tasks for collaborative search, whereas transactional tasks are the least suitable tasks because they are difficult to be divided and assigned.
