社会合作信息查寻与检索:机制、模型与特征 总被引：1，自引：0，他引：1
通过典型人肉搜索案例"辽宁女事件"的剖析,揭示人肉搜索的社会合作信息查寻与检索性质;基于该案例分析社会合作信息查寻与检索过程机制,抽象出社会合作查寻与检索的框架模型。概括总结了社会合作查寻与检索的基本特征:搜索主体的群体自主性,搜索对象的全面性,搜索过程的迭代反馈相干性和智能性,搜索结果的准确适用性,以及去中心性、共享性及自组织性,并进一步讨论了社会合作信息查寻与检索代表的两种搜索发展模式:以人际关系为基础的智能化搜索模式,以正反馈累积为动力的"再中心化"自组织模式。 相似文献

借鉴认知心理学的研究成果,构建了信息检索的认知过程模型,指出基于认知的信息获取可能是单用户完成,或是单用户通过社会求助完成,或是直接在群体范围完成。把信息查寻与检索认知模型的研究历史划分为个体认知和社会认知两个阶段,评述了两个阶段中的主要理论模型,发现无论个体认知还是社会认知都无法解释说明查寻检索过程中的合作实践。借鉴Ingwersen整体认知观思想,嵌入合作信息查寻与检索过程构建了信息查寻与检索的社会认知模型,并详述了该模型的运行机制。该模型不仅集成了系统导向与用户和认知导向的信息检索研究范式,并为合作查寻与检索找到了合理的学科位置归宿。 相似文献

In this article we investigate the expressions of collaborative activities within information seeking and retrieval processes (IS&R). Generally, information seeking and retrieval is regarded as an individual and isolated process in IR research. We assume that an IS&R situation is not merely an individual effort, but inherently involves various collaborative activities. We present empirical results from a real-life and information-intensive setting within the patent domain, showing that the patent task performance process involves highly collaborative aspects throughout the stages of the information seeking and retrieval process. Furthermore, we show that these activities may be categorised and related to different stages in an information seeking and retrieval process. Therefore, the assumption that information retrieval performance is purely individual needs to be reconsidered. Finally, we also propose a refined IR framework involving collaborative aspects. 相似文献

Despite the many implicit references to the social contexts of search within information seeking and retrieval research, there has been relatively little work that has specifically investigated the additional requirements for collaborative information-seeking interfaces. Here, we re-assess an existing analytical inspection framework, designed for individual information seeking, and then apply it to evaluate a recent collaborative information-seeking interface: SearchTogether. The framework was built upon two models of solitary information seeking, and so as part of the re-assessment we first re-frame the models for collaborative contexts. We re-frame a model of search tactics, providing revised definitions that consider known collaborators. We then re-frame a model of searcher profiles to analyse support for different group dynamics. After presenting an analysis of SearchTogether, we reflect on its accuracy, showing that the framework identified eight known truths, eight new insights, and no known-to-be-untrue insights into the design. We conclude that the framework: (a) can still be applied to collaborative information-seeking interfaces; (b) can successfully produce additional requirements for collaborative information-seeking interfaces; and (c) can successfully model different dynamics of collaborating searchers. 相似文献

Collaborative information seeking is integral to many professional activities. In hospital work, the medication process encompasses continual seeking for information and collaborative grounding of information. This study investigates breakdowns in collaborative information seeking through analyses of the use of the electronic medication record adopted in a Danish healthcare region and of the reports of 5 years of medication incidents at Danish hospitals. The results show that breakdowns in collaborative information seeking is a major source of medication incidents, that most of these breakdowns are breakdowns in collaborative grounding rather than information seeking, that the medication incidents mainly concern breakdowns in the use of records as opposed to oral communication, that the breakdowns span multiple degrees of separation between clinicians, and that the electronic medication record has introduced risks of new kinds of breakdown in collaborative information seeking. In working to prevent and recover from breakdowns in the seeking and sharing of information a focus on collaborative information seeking will point toward collaborative, organizational, and systemic reasons for breakdown and areas for improvement, rather than toward individual error. 相似文献

Collaborative information seeking: The combined activity of information seeking and collaborative grounding 总被引：1，自引：1，他引：0
Since common ground is pivotal to collaboration, this paper proposes to define collaborative information seeking as the combined activity of information seeking and collaborative grounding. While information-seeking activities are necessary for collaborating actors to acquire new information, the activities involved in information seeking are often performed by varying subgroups of actors. Consequently, collaborative grounding is necessary to share information among collaborating actors and, thereby, establish and maintain the common ground necessary for their collaborative work. By focusing on the collaborative level, collaborative information seeking aims to avoid both individual reductionism and group reductionism, while at the same time recognizing that only some information and understanding need be shared. 相似文献
