[目的/意义] 社交媒介不仅提供了用户间知识交流的平台,而且形成了知识复用的渠道。一部分社交网络用户在信息传播、知识共享等方面都能够对其他用户产生影响,称之为“小众专家”。对“小众专家”群体的研究对于社交网络中信息传播具有促进作用。[方法/过程] 以MetaFilter数据集为例,利用用户社交网络活动数据,生成用户关系网络,结合网络分析与时序分析筛选“小众专家”,分析“小众专家”群体在不同语义环境下的“稳定-迁移”特征,并提出评测指标,进行验证分析。[结果/结论] 结果显示：只有极少部分“小众专家”能够在多种语义环境下保持稳定性,而大部分“小众专家”只能在单一语义环境中保持稳定性。 相似文献

[目的/意义] 探讨用户在“豆瓣读书”发布短评的动机,尝试判断短评作为图书影响力的评估指标是否有效,以期为中文学术图书评价的Altmetrics指标建构提供参考。[方法/过程] 以CBKCI统计报告公布的被引前十的古籍类中文学术图书为样本,采用扎根理论对样本图书在“豆瓣读书”网的1 142条“短评”进行分析,探究短评的产生动机及相应短评数据的可用性。[结果/结论] 用户产生短评的动机包括讨论、分享、消遣娱乐、外界压力、情感宣泄和资料获取6个主范畴。其中,“讨论”动机是最主要的动机,其两个子动机“表达与图书有关的个人经验或想法”和“表达对图书的见解或个人解释”占所有短评数据的四成以上,表明用户不是仅复制图书部分句子或章节,而是试图找到并传播图书最有价值的部分,此类短评数据可用以评价中文学术图书价值;而“分享” “消遣娱乐” “外界压力” “情感宣泄”和“资料获取”等动机相对来说难以较好地反映用户对图书的态度和认知,不宜纳入中文学术图书Altmetrics评价指标中。 相似文献

开放存取思想迎合了网络时代信息交流的特点,开创了一种新的、高效的交流模式。开放存取包含两层含义:一是指学术信息免费向公众开放;二是指学术信息的可获得性。网络环境下的学术信息开放存取服务有多种类型,如:在线文档发布、科学家与研究组内部的直接交流、通过电子邮件的自由辩论、搜索引擎的索引与检索服务、第三方集成检索服务等。图3。参考文献10。 相似文献

Much of information policy is focused on establishing the parameters of information access—ensuring or limiting access to certain types of information. Given how central information access is to virtually every aspect of society, policy can be seen as one of the most significant forces influencing the information society. Recent events, however, have fueled changes in the ways that some governments use policy to shape access, none more significantly than the United States. This paper examines the meanings of and relationships between policy and access, as well as their key roles in society and democratic participation. Following an examination of the historical and social impacts of policies about access, the article analyzes the perspectives of the Bush administration on how policy should shape information access as an illustration of the relationships between policy and access. The paper examines the issues raised by the Bush administration’s views on access and policy and the implications of their policies for the United States, for the global information society, and for research related to information. Ultimately, the paper raises questions about the extent to which information policies about access can be used for overtly political purposes, what might be described as “information politics,” without significantly altering the meaning of information access in a society. 相似文献

Access to government information has been considered an essential element of democracy since the foundation of the American republic. Over time, the amount of government information produced has increased significantly, and the rise of e-government has made access to online government information, communication, and services equally vital to participation in society and interaction with governments. However, the outlets of free public access to government information and e-government have constricted over time, leaving public libraries as one of the only free public Internet access points in most communities. As a result, public libraries serve as a social guarantor of access to and assistance with government information and e-government services. This article first discusses the historical evolution of the means of access to government information and changes over time in responsibilities in providing such access. After exploring the interrelationships between government information and e-government, the article then details the development of the role of public libraries as guarantors of e-government access. Finally, the article examines the impacts of policy on e-government access in libraries, leading to a set of recommendations and conclusions to support the vital library roles related to e-government. 相似文献

《Government Information Quarterly》1997,14(2):143-154
There is much discussion in research literature regarding the information produced by inter-governmental organizations (IGOs) and what publications are available for use in libraries. At the same time, there is little discussion of the information policies of IGOs regarding access to IGO information. In fact, the freedom of information debate, with few exceptions, has not been extended to include IGOs. Although IGOs are made up of governmental bodies, the role of the IGO seems to be that of facilitator for state policy formation. This role fails to recognize that IGOs produce information of their own accord and make decisions which affect peoples in the member states. This article surveys the issue of access to IGO information and discusses how national debates can be extended to the IGO level. It shows both explicit and implicit information policies with case studies from the environmental information field: the European Union's (EU) directive on environmental information, and the Global Environment Facility (GEF). Three issues emerge: these are varying levels of access to IGO information, varying levels of IGO information policy, and a relative paucity of research on the subject. The principles of accountability, transparency, and public involvement are being made explicit more frequently in the documents of IGOs. However, a continuing gap between explicit and implicit policies must be bridged. 相似文献
