针对标准更新定量研究问题,以中国稀土标准体系为例,基于现行的稀土标准体系,通过检索CSSN等标准数据库,对标准更新信息进行系统分析和判断,提出把标准更新分为“一对一”和“多对一”两类,并建立标准更新的数值模型,分别对稀土国家标准、行业标准更新情况进行定量描述。通过对稀土标准体系更新方式和历年更新情况的定量研究,在一定程度上反映出稀土行业技术进步及应用规律。该方法可用于其他类似标准体系的更新定量研究。 相似文献

基于图挖掘的文本主题识别方法研究综述 总被引：1，自引：1，他引：0
本文通过文献调研分析,将基于图挖掘的文本主题识别方法总结为中心度方法、紧密关联子图查找和图聚类三种,后两者又细分为基于clique子团或类clique子团、基于图拓扑结构或结点属性聚类的方法。中心度方法通过对比文本网络中术语结点的重要度来实现文本主题的识别,紧密关联子图查找和图聚类方法则是根据文本图中术语结点和边的属性相似度来识别文本核心主题。基于语言文本网络自身特性,如何构建复杂文本关系图来同时揭示术语间的句法、共现和语义关系,如何基于术语关联和图拓扑结构识别其中的紧密关联子团,基于何种标准将紧密关联子团聚类以揭示文本核心主题,都是未来需要进一步深入研究的问题。表1。 相似文献

Macroappraisal as developed in Canada has had significant currency in archival literature over the past decade, and aspects
of its program and ideas have been implemented in other jurisdictions. For the first time, this essay probes the theoretical
and practical origins of macroappraisal in Canada since 1950 and why its originators no longer found convincing the predominant
status quo on appraisal as articulated by T.R. Schellenberg. The essay then summarizes the theory of macroappraisal as articulated
at the National Archives of Canada, and the strategic and program infrastructure developed in the 1990s to turn the new theory
into operational reality. As no archival concept is universally locked in time, the evolution and changes in the macroappraisal
program, both in theory and strategy, are also analysed in its Canadian home base over its first decade, as well as some internal
and external criticisms of it. The essay intends to illuminate the deeper context of macroappraisal, so that an international
audience may better understand its strengths and weaknesses. As the author is the principal architect of macroappraisal, the
essay consists of equal parts of archival history, theoretical analysis, and personal reflection. 相似文献

In this article, the author offers a contextualist approach to contemporary debates about new (and old) media in different historical times and geographical places. This approach, rather than starting with the internal essence of a technology and then attempting to deduce its effects from its technical specifications, begins with an analysis of the interactional and cultural systems in play in a particular context and then investigates how any particular technology is fitted into them. Building on his previous work in microanalyses of technology use in the home, and drawing on recent debates in technology studies and media anthropology, he further develops the implications of this approach, at a macro level, in terms of temporal and cultural contexts. The article concludes by reviewing the outstanding problems that still confront our field, in respect to its deeply ingrained presumptions concerning the universal relevance of what are, in fact, specifically Western (and thus contingent) relations between television, technology and national cultures. 相似文献

In late nineteenth-century USA, technological developments in paper production—a shift from a reliance on scarce cotton rag to plentiful wood—drastically reduced the price of newsprint. That decline helped overturn the reigning economics of the daily newspaper and resulted in the rise of new cheap papers with vastly expanded circulation. This novel mass press encompassed almost all Americans in the public sphere as represented by its pages. Focusing on newspapers in Detroit, this study examines the manifold consequences this shift had for the press's economics, its news agenda, and the implicit identity of the audience it addressed. The rise of a mass press in the late nineteenth century, however, was not specific to Detroit or the USA. As comparative historians have highlighted, the emergence of a mass press in Europe and elsewhere was a turning point that deeply marked the historical evolution of press systems around the globe. 相似文献

Over the past few decades, public relations has developed significantly in the West into a sophisticated management function which is recognized as an integral part of any organization's attempt to communicate with various persons, both within and outside the organization, in order to achieve its goals and objectives. However, this is not the case in the Arab world where public relations remains underdeveloped and, even when practised, is relatively unsophisticated. This paper deals with the public relations function in a prominent though controversial Arab media organization: Al Jazeera Satellite Channel. It explores how Al Jazeera has been dealing with internal and external communication issues impelled initially by its role as a satellite broadcaster spearheading changes in a vibrant Arab mediascape and subsequently by its expansion into a global broadcaster. Drawing on James Grunig's four models of communication to analyze Al Jazeera's public relations practices, the case study at hand outlines some of the communication challenges and opportunities the organization has been facing during its 10 years of existence. The case of an indigenous organization like Al Jazeera operating in a culturally distinct environment puts into perspective communications issues and complicates our understanding of how public relations is understood and practised outside the normative Western public relations paradigm. 相似文献

This paper examines televisual parody as a media literacy educator, and the potential of parody to channel the powers of comedy and entertainment in order to “teach” the techniques and rhetoric of televisual texts and genres. It focuses on the case of the hugely successful and popular animated parodic sitcom, The Simpsons, and its playful attack on advertising and promotional culture. Currently in its 16th season, The Simpsons broadcasts to approximately 60 million viewers in 70 countries weekly, offering a playful critique of television from within the television frame. 相似文献

This article discusses the changes that are occurring in the world of cataloging. It argues that these changes need to be coordinated. It also discusses the feature of current OPACs, FRBR, the Paris Principles and its proposed replacement (ICP), AACR2 and its proposed replacement (RDA), ISBD, and the relationships between and among these standards. It argues that the syntax of ISBD is an essential component of RDA and all future international and national cataloging codes. 相似文献

How have the three services-indexing, reference (including history of medicine), and interlibrary loan-been provided throughout the years by NLM, and how have they been used? At the present time of great growth and development, the use of the computer has influenced these services and will continue to figure prominently in plans for the future. NLM's services often have not been well or correctly used by its public, even by librarians. Some of its services, however, need to be provided in more depth and on a higher scale, and they should be publicized more widely. History shows that NLM has been faithful to its basic charge and has gone far beyond it in its service to the medical, educational, and library communities. Medical librarians are most fortunate that such a great national resource exists to provide materials and services to fulfill the needs of their libraries. 相似文献
