众多叙词表及术语资源由于资源分散、更新维护慢、不能满足数据大规模应用需要,导致应用情况不理想。叙词表的集成化可对现有信息资源进行充分整合,有助于优化知识组织体系,拓展术语资源的应用范围。本文提出的叙词表集成化体系框架涵盖了标准规范体系、词表集成化支撑体系、词表集成化概念体系、叙词表集成化过程和方法以及系统服务与应用五个方面。集成化过程是在多来源术语集成构建词汇集成库的基础上,进行概念映射、概念融合与关系校验实现概念和概念关系的语义集成,构建一个覆盖多学科领域的、语义关系多样的集成化词表。最后,本文提出了推进集成资源的智能化服务和社会场景应用的具体策略,推动叙词表资源的可持续发展。 相似文献

信息过载现象导致发现并获取有用信息变得越来越困难,用户急切需要精准的知识发现和问题解答服务,通过对当前实现精准知识发现的主要技术方法进行分析,本研究分别采用基于传统知识组织构建方法和基于深度学习的方法,面向湿地领域进行语义知识组织体系的构建和精准发现实验。实验分析证明,传统知识组织方法无法单独支持特定主题的精准知识发现,尽管基于词向量的深度学习方法可以有效弥补传统知识组织系统的局限,但会受到计算语料规模和质量的限制。因此,本研究最终提出融合知识组织与认知计算的基本思路和体系框架,分析了融合方案所涉及的关键技术,这对于构建新一代开放知识服务系统具有重要指导意义。图3。参考文献15。 相似文献

文章通过对开放存取(OA)领域中"模式探索、资源建设、用户服务"研究发展脉络的梳理,对当今学术界基于本体的用户服务理念和基于Folksonomy的用户服务思想两大主流的用户服务思想进行了对比分析。在此基础上,基于本体与Folksonomy融合的视域,尝试构建了开放存取(OA)用户服务体系框架模型,并对该框架模型中的6个主要核心环节进行了阐述。最后从语义性、动态性、多样性3个方面对基于本体与Folksonomy融合的开放存取(OA)用户服务体系框架进行了探讨。 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

This essay investigates key moments in the history of personal digital assistant (PDA) marketing to women. Analyzing promotional texts for three PDAs that received considerable press coverage from 1999 to 2001, this essay explores the cultural significance of the convergence of anxieties about women's place in the gendered division of labor with the computer industry's changing marketing imperatives. Drawing on an array of promotional texts, including news articles, press releases, promotional Web sites, and ads appearing in newspapers and magazines, this paper tells the story of how the computer industry aimed to sell smaller, faster computing devices to women while promising to mediate and thus reproduce women's overwork as paid and familial laborers. After experimenting with the PDA as a sexy fashionable gadget for working women, marketers approached women as mothers with “Audrey,” an Internet appliance designed for the kitchen. 相似文献

This study explores the attitudes and actions of bank managers toward communication spending during recession. Results of this study indicate that organizational leaders cut communication spending early during recession and also erroneously rely on the bank's financials to mitigate irrational customer withdrawals. This research is used to illustrate the need for public librarians to meet the needs of bank stakeholders when their institution ceases to communicate during crises, for academic librarians to educate students in undergraduate and graduate programs regarding heightened information needs during recession, and for corporate librarians to understand a potential avenue for competitive advantage during recession. 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 Many events over the past decade have jeopardized the library's ability to fulfill its basic mission resulting in a shift of information delivery paradigms. Interlibrary loan, document delivery and resource sharing have become essential rather than peripheral and funding patterns are reflecting this philosophical shift. There is renewed interest in cooperative collection development and multiple options for meshing document delivery with an existing ILL program. Within this environment under a redefined mission statement, the Rasmuson Library, University of Alaska Fairbanks, addresses these shifting paradigms and has implemented a program to meet the information needs of its patrons. 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

Three public libraries were examined to assess their patterns of social interaction as determined by oral communication, with the primary aim of the research being to identify liaisons within the communications network. A subsidiary aim was to determine the 'fit' of the emergent with the formal organizational structure. It was possible to compare the structures of the organizations in two cases, and in both of these cases the emergent (informal) structure matched the formal structure quite closely. Library and Information Center managers need to attach some degree of importance to such knowledge as the informal and formal structural fit may impinge upon organizational effectiveness. 相似文献
