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

认知计算是感知和思考信息处理过程的学科系统。认知计算系统从已有的书目数据中提取相关概念和个体关联,利用机器智能,创造独立于书目格式和以往学习经验之外的数据模型。新的书目著录模式,强调数据科学、认知体系与RDA编目规则的有机结合,分析认知计算系统中“数据层—信息层—知识层”几个层面与FRBR书目世界3组实体的关系,妥善处理编目工作中数据内容庞杂、信息动态分布与知识隐含层级等问题。借助数据挖掘、视觉认知与自然语言处理等认知手段,文献资源编目工作需要经历知识获取、知识编码、知识推理与知识验证4个环节,最终实现书目数据的信息化,为图书馆馆藏的合理布局、阅读推广的开拓创新与个性化信息服务的构建提供智能支撑。 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

我国自从西方引入“Information Science”至今，由于盲目的学科概念的借鉴和本土学术发展的滞后，导致了种种情报与信息的争鸣和讨论。本文从学科元概念出发，以学科社会实践为基点，以信息管理链为依托，循序渐进地论述了中国社会环境下情报学与信息管理学的学科定位问题。 相似文献

随着国家开展“新工科、新医科、新农科、新文科”学科建设，高校图书馆学科服务需要改变现有模式。文章采用文献调研法、对比分析法、问卷调查法、案例研究法，调研中外现有学科服务模式，提出应用项目管理思想来构建面向“四新”的学科服务模式，构建学科服务项目管理模式框架，分析学科服务项目管理模式的运行过程；以东南大学图书馆面向“新工科”的高价值专利培育服务项目为例，阐释项目管理思想应用于图书馆学科服务的可行性、实施过程及效果。研究发现：该模式能够服务于学科交叉融合，与“新工科全面深化、新医科融合发展，新农科高位推进，新文科布局未来”目标相统一，能够提高图书馆的学科服务水平和高校图书馆的服务质量。 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

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

Most studies of collection development mask inadequate theoretical underpinnings with facile assumptions and dazzling statistical manipulations. This essay, in moving toward a model for collection development within both specific collections and library systems as a whole, seeks to demonstrate the full range and complexity of relevant factors. An enlarged theoretical grasp should help highlight both the possibilities and the challenges of existing approaches. One result could be a shift toward gaming or simulation techniques as more realistic analytical tools. 相似文献

An annotated list is presented describing seventeen periodicals that cover significant aspects of the gay, lesbian, bisexual, and transgender (GLBT) community and their culture in whole or in part, with popular content rather than an academic or research focus. The titles included are a selective and representative sampling. The entry for each periodical includes the following information: periodical title, publisher/editor and address, basic information, publication data, content, Internet information, an abstract/annotation, and evaluative statement 相似文献

SUMMARY Ariel files are the starting point for electronic delivery of interlibrary loan articles through ILLiad, Virginia Tech's interlibrary loan system. Despite some advantages to electronic delivery of articles to their desktops, a large majority of ILL customers continue to prefer print on paper delivery rather than electronic delivery. This fact has implications for introducing additional electronic services. Correctly choosing what services to impose on library customers, and what services to offer as value-added options, is fundamental to maintaining the credibility of libraries during these times of rapid change. 相似文献

Library Journal's 2011 Ebook Penetration and Use in U.S. Libraries Survey testifies to e-books’ increasing popularity in academic libraries. This review tracked literature published from 2005 that focused on academic librarians’ best practices for acquiring, cataloging, maintaining, and promoting e-books at their institutions. Some of these practices include implementing trial accesses, considering institutional requirements, providing an e-book presence in the library catalog, monitoring usage statistics, and utilizing the library Web site for promotional efforts. 相似文献

SUMMARY There are between fifteen and twenty U.S. libraries that collect publications from Central Asia, defined here as Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. Collection development responsibility for these countries tends to rest with the Slavic selector, the Middle East selector, or both, divided by language. Vendors who can supply this material mostly also supply publications from other countries of the former Soviet Union. The author briefly discusses the history of collecting from this region and the results of a survey conducted in 2004. She presents evidence indicating that the main reason U.S. libraries are not receiving more books from the region is most likely because they are not being published, not because vendors are doing an inadequate job. 相似文献
