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

“人肉搜索”的相关法律问题研究 总被引：1，自引：0，他引：1
"人肉搜索"作为一个新的社会现象虽近几年才出现,然而由其引发的问题和讨论却受到了全社会的广泛关注.尤其是由于缺乏有效的法律规制,"人肉搜索"时常涉及侵犯公民隐私权、公然在互联网上侮辱、诽谤他人等违法行为.该文通过对人肉搜索进行详细分析,以法律角度解析人肉搜索及相关法律问题,从而提出法律思考与建议,以期从制度上加强对人肉搜索的引导和管理. 相似文献

[目的/意义]作为健康信息的一种,在线医评信息对用户医疗决策十分重要。研究用户查寻在线医评信息的过程,挖掘存在的障碍,有助于优化医评网站设计、促进医生在线服务和满足用户健康信息查寻需求。[方法/过程]采用检索实验、内容分析、发声思考和问卷调查等方法,从查寻表现、查寻阶段和查寻障碍3个方面分析在线医评信息这一特定情景下用户的查寻行为及存在问题。[结果/结论]结果显示教育水平和健康信息检索技能与在线医评信息查寻表现正向相关。在线医评信息查寻过程模型包括医生初筛、医评信息检索、浏览、对比、验证和利用6个阶段。健康信息检索技能和甄别能力弱、医评网站评论数量少、医院官网和医评网站可用性差以及医评网站与线下医疗服务融合程度低是影响用户查寻在线医评信息的主要障碍。 相似文献

本文以中国C9联盟高校为研究对象,运用社会网络分析方法,对高校与其他社会组织之间以专利为载体的协同创新活动进行计量分析,探讨我国高校专利合作的主要特征与模式,并选取典型案例深入挖掘有效的产学研协同创新模式。研究结果表明:高校与其衍生企业、所在地周边企业和大型企业集团的合作共同构成了当前高校专利合作网络的主体部分;高校的专利合作行为大多属于偶发、零散和非系统性的合作,真正具有战略目标的持久深入合作关系较少;清华大学与富士康集团的专利合作案例表明,高校与企业应发挥各自在协同创新链条上的长处,探索建立风险共担的利益分配机制,才能逐步形成可持续发展的"产学研"合作生态环境。 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

Search patterns of documents and information requests are their better or worse representatives only, so it is important to carry on examinations on possibilities of designing self-learning information retrieval systems. Another important question is to elaborate such an organization of document search pattern set as to obtain an acceptable response time of the information system to a given information request.A self-learning process of the proposed information system consists in the determination—on a set of document and information request search patterns—of the similarity relation according to L. A. Zadeh.The organization of a set of document search patterns proposed in the paper ensures the limitation of document search pattern set searching process—when retrieving a response to a given information request—to one (or several) subset from previously determined subsets. This makes the information system response time acceptable. The proposed information retrieval strategy is discussed in terms of fuzzy sets. 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

Collaborative information seeking often takes place in co-located settings; such opportunities may be planned (business colleagues meeting in a conference room or students working together in a library) or spontaneous (family members gathered in their living room or friends meeting at a café). Surface computing technologies (i.e., interactive tabletops) hold great potential for enhancing collaborative information seeking activities. Such devices provide engaging direct manipulation interactions, facilitate awareness of collaborators’ activities, and afford spatial organization of content. However, current tabletop technologies also present several challenges that creators of collaborative information seeking system must account for in their designs. In this article, we explore the design space for collaborative search systems on interactive tabletops, discussing the benefits and challenges of creating search applications for these devices. We discuss how features of our tabletop search prototypes TeamSearch, FourBySix Search, Cambiera, and WeSearch, illustrate different aspects of this design space. 相似文献
