链接内容分析视角下的科学网博客评价探索 总被引：1，自引：0，他引：1
针对传统链接分析重链接形式而轻链接内容的倾向,文章提出了链接内容分析法,并以此为基础提出了"被好友"指标这一新型博客影响力评估指标。并运用该方法对科学网博客进行了实证研究,揭示了科学网博客的核心博客并以可视化形式展示了其社区结构,从而论证了对链接进行内容分析的意义和可行性,为链接分析和博客评价研究提供了新的方法和思路。 相似文献

以网络计量学领域的网站链接数为基础,研究网址入链分布规律。首先,通过研究中网站之间的链接关系,选定入链数作为研究对象,并获取原始数据;接着,利用最小二乘法、K-S检验算法以及M.L. Pao教授提出的指数不为2时的逼近c值的估计公式对数据进行洛特卡定律拟合,发现网络计量学领域的网址入链分布并不服从洛特卡定律。最后,讨论造成不服从洛特卡定律的原因。 相似文献

链接分析对引文分析的启示:从PageRank到Paperank 总被引：1，自引：0，他引：1
链接分析的发展受引文分析理论的影响,在基本假设前提与应用等方面,链接分析都与引文分析相似,例如,网络影响因子来源于期刊影响因子,共链分析来源于共被引分析.另一方面,网络的动态性赋予了链接分析一些特性,这些特性对于引文分析研究有启示作用.本文在简要介绍引文分析与链接分析的相关理论之后,基于链接分析中的PageRank算法提出了Paperank算法,用于引文分析.在对算法的论证过程中,笔者选取了SCEI中的"Webometrics"相关论文为样本,通过比较这些论文的Paperank值与被引次数,凸显Paperank算法的优点.最后,本文提出了Paperank算法的应用前景--学术期刊论文数据库的检索结果排序. 相似文献

通过本节的研究我们发现:①网站各层在规模、文件类型和所拥有的网络链接数量等方面的变化具有明显的规律性,它取决于各层的功能定位;②对于链接密度和页面平均链接数在网站各层之间的变化,本研究未能给予精确的描述,仅就其变化趋势和原因进行了分析。从网站各层功能及其在链接上所表现出的特点来看,功能定位不同的层次,链接出现的频率是不同的,甚至应该能以链接出现频率的变化确切地判断其相应的功能定位,但依靠链接密度和页面平均链接数难以实现这个目标,必须考虑建立与页面功能和链接频率都相关的新的度量指标;③本研究结果证实,我们通过比较网站的网络影响因子筛选出的9个研究对象,其信息组织是比较合理的。这暗示我们,网站信息资源组织的合理程度与其网络影响力可能具有一定的联系。 相似文献

链接分析与引文分析的比较 总被引：13，自引：1，他引：12
网络影响因子沿用了期刊影响因子对引文分析的基本思路,但作为链接分析的指标,用于网络环境中的质量评价是不可靠的。可以根据Pagerank算法提出用于论文质量评价的Pagerank算法;可以根据引文衰减系数提出"链接衰减系数"和"平均链接时距"用于研究网页的老化规律。理想的链接分析工具应当是一种专用搜索引擎。 相似文献

本研究在总结现有以共链分析和社会网络分析为主的学术网络局部结构识别方法的基础上,提出了改进的两步式K核分析方法,首次引入了复杂网络中的社区识别算法进行链接网络的分割,并尝试通过适用性评测验证快速聚类算法在同质Web链接网络的主题结构识别方面的有效性.最后的实验结果表明,本研究提出的改进K核分析方法可以有效地发现存在于链接网络中的主题聚类现象;同时研究中引入的快速聚类算法对以93所大学网站进行了聚类并获得六个主题类.通过聚类准确率指标计算,该聚类方法的平均准确率为72%.以上结论证实了本研究中采用的从链接关系度量,数据矩阵构建、到链接网络分析的方法体系是有效的. 相似文献

Israel’s public diplomacy efforts in the U.S. are aimed at garnering American public support for Israeli foreign policy. This study aims to identify the networks of Israeli public diplomacy toward the United States. Using the theoretical frameworks of networked public diplomacy and strategic narrative, the authors try to understand how network strategy is used and information is circulated to create a strategic narrative. Therefore, the two methods of social network analysis and qualitative content analysis are applied to identify the networks of Israeli public diplomacy in the United States and the content produced by it. The study finds that in Israel’s public diplomacy model, the networking method stands in contrast to its government-oriented strategic narrative. Thus, new forms of communication are applied to conduct old strategies. The research identifies four types of actors who apply new public diplomacy techniques and dissects the strategic narrative they employ to affect the American public in the service of Israeli interests. Despite the effort to apply new forms of public diplomacy, strategic narrative production and dissemination remain highly governmental and closed, which is indicative of the persistence of old forms of public diplomacy. 相似文献

ABSTRACT This article explores the concept of service branding in the context of libraries and information organizations. We discuss community perceptions of library brand value from the librarian's perspectives in the context of public and academic libraries. Librarians’ thoughts and viewpoints in improving the community's library experience are also discussed. The findings highlight the importance of improving the library's visibility, creating appealing ambience, and developing a strategic branding plan in order to provide robust, compelling, and meaningful experiences for their community. 相似文献

The development of marketing activities for an academic library as an outgrowth of an overall library strategic plan can assist in clarifying which key resources and services should be promoted and in developing the optimal activities for communicating their benefits. Marketing as an ancillary process to strategic planning can increase awareness and use of library resources and services among targeted user groups and can present a clear, consistent image to students, faculty, and administration as to what the library offers to the life of the university community and validate its continued funding. A permanent library marketing committee is the best means for coordinating library marketing activities. 相似文献

China's soft power campaign has spawned many scholarly studies on it, but few have examined its rhetorical aspect. Through keyword analysis, this research examines strategic ambiguity in China's public affairs rhetoric surrounding the Six Party Talks over North Korea's nuclear program. The two keywords, ‘the Six Party Talks’ and ‘da ju’ (big picture, overall view), are semantically open and central to China's rhetoric in defining ‘What is it?’ and ‘Why is it?’ with regard to the talks. Analysis shows that strategic ambiguity contributed to some of China's goals. However, it was not adjusted when it stopped working. Its effectiveness was undercut by certain inconsistent messages, and da ju failed to differentiate between domestic and international political context and was also culturally maladaptive. This research contributes to public diplomacy and public affairs rhetoric research. 相似文献

The crisis in Ukraine has accentuated the position of Russian television as the government’s strongest asset in its information warfare. The internet, however, allows other players to challenge the Kremlin’s narrative by providing counter-narratives and debunking distorted information and fake images. Accounting for the new media ecology—through which strategic narratives are created and interpreted, this article scrutinizes the narratives of allegedly fake news on Channel One, perceiving the fabricated stories as extreme projections of Russia’s strategic narratives, and the attempts of the Ukrainian fact-checking website Stopfake.org to counter the Russian narrative by refuting misinformation and exposing misleading images about Ukraine. Secondly, it analyses how Twitter users judged the veracity of these news stories and contributed to the perpetuation of strategic narratives. 相似文献

ABSTRACT To raise the library's profile within the campus community, it is critical to create a strategic plan and align library goals with those of the university. At George Washington University's Gelman Library, the instruction librarians gained internal and external support to hire two new instruction librarians to better support collaboration with the new university writing program. The library then used assessment data to successfully advocate for an additional two positions. 相似文献
