Abstract This study examined the task type as an important factor in collaborative information seeking activities, devoting special attention to its impacts on collaborative information seeking behavior, awareness and sentiment. Collaborative information search experiments were conducted on a collaborative search system—Coagmento—for three different types of task (informational, transactional and navigational). System log, surveys and semi-structured interviews were used to collect data, with quantitative and qualitative analyses carried out on the data which related to 12 participants in four groups. Quantitative analysis employed SPSS 20, while qualitative analysis was carried out using ATLAS.ti. Through our research, we found that the task types have impact on users’ collaborative information seeking behavior in terms of web page browsing, search and image using, as well as interact with task awareness. A collaborative team approach is more suitable for completing the informational task than transactional and navigational tasks, while the task type also influences the sentiment. Concretely speaking, the transactional task causes more negative emotions.

任务类型对协作信息搜索行为的影响

摘要这项研究将任务类型视为协作信息搜索活动的重要因素，并特别关注其对协作信息搜索行为，意识和情感的影响。在协作搜索系统Coagmento上针对三种不同类型的任务（信息，事务和导航）进行了协作信息搜索实验。使用系统日志，调查和半结构化访谈收集数据，并对与四组中的12名参与者相关的数据进行定量和定性分析。定量分析采用SPSS 20，而定性分析则采用ATLAS.ti。通过我们的研究，我们发现任务类型会影响用户在网页浏览，搜索和图像使用以及与任务意识的交互。协作团队方法比事务和导航任务更适合完成信息任务，而任务类型也影响情感。具体地说，交易任务会引起更多的负面情绪。
