协同搜索过程中用户交流内容与模式研究

Contents and Patterns of Users’Communication in Collaborative Search

[目的/意义]旨在分析协同搜索用户在信息搜索任务过程中的交流内容与模式,从而理解协同搜索用户的关注重点与搜索过程。[研究设计/方法]基于书籍交互检索平台(CLEF-Social Book Search)设计实验,共招募18名被试完成两种搜索任务,通过录音记录对话并对其进行编码和分析,总结交流内容特征和模式。结合任务类型、认知类型组合、服务器记录的搜索交互行为日志以及问卷收集的搜索体验进行了探索分析。[结论/发现]从交流内容上看,协同搜索用户主要理解与评判书目信息、商讨搜索任务计划;比起认知类型不同的用户,相同认知类型的用户在操作交互方面交流更多,在评判决策方面交流较少。交流模式依据讨论内容比重可分为理解评判型、评判主导型、均衡交流型三种,评判主导型用户的任务完成满意度最高。[创新/价值]协同搜索用户的交流反映出搜索过程中需要与同伴商讨协同的焦点,也是需要系统提供协助的重点,给协同搜索系统设计提供一定参考。本研究针对协同搜索的交流内容设计的编码系统对相关的协同交流研究也有借鉴意义。

[Purpose/Significance]This study aims to explore communication contents and patterns while people are searching collaboratively,and tries to understand the characteristics of collaborative information search.[Design/Methodology]The experiment was designed based on the book interactive retrieval platform called CLEF-Social Book Search.Eighteen collaboration participants were recruited to laboratory to complete two different types of book search tasks.Users’interactions with the system during their search were recorded through the backend server.Communication contents of collaborative searchers were recorded,coded and analyzed.Then the contents’characteristics and communication patterns were concluded.Exploration was conducted with the consideration of the task and cognitive type combination,logs of interactive search behavior recorded by server and search experience collected by questionnaire.[Findings/Conclusion](1)Communication contents:Collaborative searchers mainly discuss about the understanding and judgement of books and task plans.They have more discussion about task understanding in the goal-oriented task than in the open-ended task.Searchers of the same cognitive style communicate more about operations than searchers of different cognitive styles,while less about judgements.(2)Communication patterns:Communication patterns can be divided into three groups including understanding and judging group,judging-orientated group and balanced communicating group according to the proportion of discussed contents.Judging-oriented group are relatively more satisfied with the results than the other two groups.[Originality/Value]It has been found that collaborative searchers need to discuss about collaborative focuses with their partners during the search,which the system should significantly facilitate.This study helps understand more about collaborative search by analyzing communication contents and patterns,which may provide inspiration for collaborative search system design.In addition,the coding system of collaborative search communication contents offers reference for other collaborative communication research.
