情报与信息、数据、知识、智慧、智能的关系,以及信息链、DIKW链在分析这些概念及关系时所体现的价值,都是情报学中最基本、最核心且尚未达成共识的理论问题。本文依据不同定义的内核,将现有的情报定义归纳为军事说、文献—知识说、企业说三种观点;利用文献分析法、概念分析法以及案例分析法,立足于中国情报实践,综合各种观点的合理之处,在取最大“公约数”的基础上凝练出情报的新定义:情报是为特定目的、在特定时间传递给特定对象的特定关键信息;从多源视角对该定义进行分析,并整合了信息哲学、全信息理论以及DIKW链的代表性观点,优化了现有的信息链理论,进而提出了新的信息链。图1。参考文献45。 相似文献

文章分析了数字出版“免费”赢利模式的概念、前提条件、实现路径和未来发展。通过对数字出版赢利模式的文献梳理,运用经济学思维,并结合当前数字出版产业实际运行经验进行理论反思。数字出版的“免费”赢利模式是指企业系统内由数字出版活动组成的价格、注意力和数据的结构链,及企业这个结构系统与外部环境的耦合关系。“免费”赢利模式成立的前提条件是信息产品和服务的低边际成本,心智交易成本的降低和免费的非理性快乐。其实现路径依赖于注意力与数据的多少和注意力与数据的转化效率。它的未来取决于宏观经济稳定增长的预期,注意力的开发程度,以及数据与隐私权之间的矛盾关系。 相似文献

科学文献关键词链的概念──一种统计分析方法 总被引：4，自引：1，他引：4
科学文献关键词链也象引证链一样，能将众多离散的科学文献、科学著者等有机地“链接”成一个有机的群体，分析这些群体，对研究文献规律、著者规律、甚至学科规律都是至关重要的。对科学文献关键词链的结构关系进行定量研究，将可能会开拓出一种类似于引证分析方法的方法。本文试就科学文献关键词链的概念、引文献群、引著者群及群中著者的权数、统计分析的应用前景等几个问题进行初步论述。 相似文献

一、载体论与本体论《新闻大学》第17期发表的王洪祥同志的《有关信息和新闻的几点断想》,观点新颖,发人深思。但在这篇论文中,有两个提法,有点自相矛盾。一是“新闻是信息的载体”,指的是载体与载波的关系,新闻是“载体”,信息是“载波”;另一是“新闻是社会上具有传播价值的信息”,指的是种属关系,新闻是“种”,信息是“属”。王文前一句说新闻是“信息的载体”,后一句话又说新闻是“……的信息”,那么,新闻究竟是信息还是 相似文献

This article surveys a sample of sources of the information about Romania available to British readers in nineteenth century British newspapers and periodicals. It traces first contacts between the Romanian lands and Britain after the union of the principalities of Wallachia and Moldavia in 1859, then after their independence from the Ottoman Empire. The article highlights an increased Romanian interest in British periodicals, which reported and reviewed Romanian literature and scholarship. The article concludes that nineteenth century British newspapers and periodicals offer a great variety and wealth of new material previously unavailable or unknown to researchers. It also states that only a portion of a large quantity of this material has been indexed and is therefore available via the bibliographic sources mentioned in the article. The author argues for the need of a new and updated British-Romanian bibliography, which can draw on new online resources offering access to thousands of new newspapers and periodical records. 相似文献

ABSTRACT The paper looks at library approval plans for material published in Slavic, East European, and Eurasian countries from the selector's point of view. Reasons why a selector would or would not want one are examined. Success with approval plans requires monitoring receipts, as well as good and ongoing communication among the selector, the acquistions department, and the vendor. A preliminary list of vendors offering approval plans for the countries of the region appears in the appendix. 相似文献

ABSTRACT The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed. 相似文献

ABSTRACTIn today's current political environment raising support for millage renewals, bond campaigns or even millage continuations for public libraries is affected by national politics, and a tendency towards tax aversion on principle across the country. The lessons we can learn from the governing boards of small and rural public libraries are worth raising up to a greater national consciousness. Board governance, community consciousness, and facilities management are clear and logical tools that elected boards of public libraries can use to politick for support of libraries. 相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire. 相似文献

Chromebooks and the G Suite group of products, like Google Search, Gmail, and Google Docs, have rapidly expanded in American schools during the past 5 years. The impact of one-to-one Chromebook devices and the pervasive use of Google's software products in American education cannot be overstated. This article explores some of the influences of these products on research, based on the experiences of a librarian and technology coordinator at an elementary education level. The author has several suggestions for effective research with these products in mind. 相似文献

Library historians can learn a great deal from studying the gender of authorship and institutional affiliation of a scholarly journal. The focus of this study is to examine these two aspects of journal production in library history to see who is producing published research in this field. Twenty-three years of Libraries & Culture were chosen as the target volumes. The study reveals that more men than women published in library history as well as locating which institutions were represented. This type of information is usedful to the library historian engaged in the analysis of published scholarship, and more generally to scholars with an interest in patterns of literature production in fields closely related to the social and behavioral sciences. 相似文献

ABSTRACT The history of the almanac in Croatia is reconstructed through primary research in bibliographic and archival sources. The almanac is a vehicle for knowledge communication in informal contexts, engaging both oral tradition and literary forms traceable to medieval literacy and ways of structuring knowledge. The history of the almanac in Croatia reflects the changing context of the book trade, literacy, and the evolution of language. Four main stages are identified: (1) the beginning of the annual almanac in the seventeenth century; astrological almanacs reflecting the sensibility of the Baroque period; (2) the Enlightenment's stimulation of almanac publishing in the spirit of contemporary secular reforms in agriculture and education; (3) nineteenth-and twentieth-century almanac trade, showing complex and overlapping networks for the production, distribution and appropriation of printed almanacs;(4) roughly the end of World War II, when the almanac slowly moved out of the role of a popular mass medium and into specialized niches represented by regional, diaspora, and religious almanacs. 相似文献
