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

国家叙词库采用以《汉语主题词表》为中心表、其他中文叙词表向中心表映射的模式进行基于概念的语义集成。为了研究学科交叉对国家叙词库语义映射造成的影响,本文选取八部叙词表中环境科学大类5 120个概念,与《汉语主题词表》环境科学大类8 329个概念进行映射实验。通过计算机自动匹配发现,多表映射存在一个概念等同映射到多个概念,多个概念等同映射到一个概念等逻辑问题。本文以实例形式分析这些逻辑问题的存在形式,并从概念专指度、概念语义模糊、语义关系结构、学科背景等方面分析产生这些逻辑问题的主要原因;在此基础上,提出解决这些逻辑问题的原则以及映射完整性的判定规则。图16。表5。参考文献14。 相似文献

网络叙词表的组织结构及优化模式研究 总被引：2，自引：0，他引：2
网络叙词表是重要的网络信息组织工具,目前已投入使用的网络叙词表根据宏观结构的不同可以分为3种类型,它们主要用于网络信息资源描述和检索系统两个方面。虽然网络叙词表在组成上与印刷本叙词表没有大的差异,但在其生成和实现方式上有很多不同点,而且它在入口界面、词汇控制和标识系统3个微观结构方面也有着显著的特征和优势。同时,网络叙词表在宏观结构和微观结构方面也有必要进行一系列优化,以完善其使用功能。 相似文献

传统叙词表的本体化构建是目前叙词表发展的重要方向。当前叙词表转换为本体的描述语言有XML(S)、RDF(S)、SKOS、OWL等,文章通过对几种典型的描述语言和叙词表之间的语义关系进行映射分析,从描述能力、人工干预、应用性三个层面总结了描述语言在表示叙词表语义关系方面的差异性。该研究不仅有助于传统叙词表在语义环境下进行发展,而且对于本体描述语言的完善具有非常重要的作用。 相似文献

中文叙词表的语义化转换 总被引：1，自引：0，他引：1
[目的/意义]随着语义网与关联数据的兴起与发展,采用SKOS语言对叙词表进行语义化描述成为主流,这为叙词表在网络上的发布、共享以及在网络环境下的应用提供新的契机。[方法/过程]以《汉语主题词表》为例,对中文叙词表的语义化表示、验证和关联数据发布进行探索。首先,制定基于SKOS、SKOS-XL和SKOS扩展的叙词表语义化表示方案, 实现对叙词表的无损语义描述, 开发基于N-Triples格式的词表语义化转换程序, 使大规模词表的语义化转换更加简单高效;其次,采用新兴的SPIN框架对语义化词表的完整性进行验证, 为SKOS词表的正确性与合法性提供保证;最后,采用“Jena TDB+Fuseki+Pubby”的组合将SKOS/RDF词表数据在网络上发布为关联数据,并开发词表关联数据检索界面。[结果/结论]实验结果表明,采用本文的方法能够实现整个《汉语主题词表》的高效语义化转换、验证与发布,促进中文叙词表在网络上的共享与应用。 相似文献

基于SKOS 的国防科学技术叙词表向本体的转换研究 总被引：2，自引：0，他引：2
本文对通过<国防科学技术叙词表>来构建国防科技领域本体进行了研究.文章简要介绍了几种本体描述语言,在详细描述W3C 新推出的本体描述语言标准SKOS 的基础上,结合<国防科学技术叙词表>分析了SKOS 对于概念、属性、映射的描述方法.SKOS 具有简单、系统、全面的特点,使得本体的构建更为方便、高效,为国防领域的知识共享和重用奠定了基础.在本文的实例部分,介绍分析了<国防科学技术叙词表>,尤其是词表中的字顺表所包含的主要语义关系,之后节选了词表的枪械部分段落,在详细分析枪械体系中的概念和其中的关联关系等的基础上完成了本体的转换. 相似文献

叙词表词汇转换系统的设计 总被引：5，自引：1，他引：4
本文在借鉴国外叙词表转换系统研制方法(集成词表)的基础上,以《汉语主题词表》、《社会科学检索词表》和《经济学管理学论文题录索引词汇表》三种汉语叙词表为实验样本,结合我国叙词表的特点,以金融银行学科为例,用计算机程序设计了一个实验性的叙词表词汇转换系统。实验表明该系统的词汇转换率达到78％—87％。 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

This article describes a study of the two most popular plagiarism-detection software platforms available on today's market—Turnitin (http://www.turnitin.com/static/index.html) and SafeAssign (http://www.safeassign.com/). After a brief discussion of plagiarism's relevance to librarians, the authors examine plagiarism-detection methodology and conduct a review of the current literature regarding plagiarism-detection efficacy. To evaluate detection efficacy for Turnitin and SafeAssign, the authors constructed a brief study in which twenty sample papers containing portions of plagiarized material were submitted to each platform. The results show that Turnitin had the highest overall success at plagiarism detection with an 82.4 percent detection rate. Additionally, both platforms had a combined false-positive detection rate of 16.8 percent. The authors conclude that close review of material suspected of plagiarism is still essential for proper identification. 相似文献
