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

简单知识组织系统与汉语主题词表 总被引：3，自引：1，他引：2
简单知识组织系统(SKOS)是W3C组织语义网下的工作组织发布并维护,为知识组织系统的表达提供强有力且简单的机器理解方式。它的建立为叙词表的形式化表达提供了概念、模型,使各叙词表之间、叙词表与本体之间的映射成为可能。如何利用SKOS,使叙词表在词义检索中得到更好地应用,实现用户检索请求的语义本体化,将是叙词表研究者更大的挑战。 相似文献

叙词表具有清晰的语义结构,便于从中抽取概念和关系,目前已有十多种叙词表被用各种方法转换为本体。叙词表转换为本体的难度依赖于叙词表本身的特点。我国《汉语主题词表》有自身的一些特点和不足,转换过程中应对叙词及其存在关系明确界定,把握四个方面的基本原则。以特定应用或特定领域为核心,《汉语主题词表》在转换为本体的过程中,需要调整叙词表中概念之间的关系:一是核心概念的选择;二是概念之间关系的改造。 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

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

Abstract The Russian government is exerting increasing control over the country's media, although the media are resisting. This government-media conflict is relevant to Western academics and libraries, because the variety and quality of Russian periodicals is at stake. In addition, if the media are constrained, publishers of books are likely to experience restrictions, too. The difficulties the government is having in controlling the media, however, are a measure of how much Russia has changed. At the same time this conflict is occurring, book publishing is thriving. Official statistics show the number of titles published surpassed even the previous record set in 1977. Planning is in progress to restructure the state book industry sector, including publishing, printing and distribution. Book prices have increased more rapidly than inflation, and postage costs have also increased. Russian Press Service is doing its best to keep its prices to Western libraries down. 相似文献

SUMMARY Describing her experience of establishing an Electronic Document Delivery Service at the library of the Lahore University of Management Sciences (LUMS), the author discusses the various issues, which significantly effect the net cost, delivery time and management process of providing such a service by a library in Pakistan. While presenting multiple options leading to an effective solution, the advantages and disadvantages of each option have been highlighted, and their implications, with particular reference to Pakistani libraries, have been discussed. The various points to be considered by Pakistani Librarians, while selecting a commercial Document Provider, have also been discussed. In the end, the author discusses the potential of using the Electronic Document Delivery facility as a time-saving and cost-effective tool for Resource Sharing among libraries in Pakistan. 相似文献

ABSTRACT No one can predict what document delivery will look like in the future, but librarians must guard patron confidentiality even in an electronic environment. This time it isn't an easily solved problem like finding another way of recording circulation than handwriting patron names onto circulation cards, it is instead the tracking of personal information attached to electronic text supplied by publishers that is a potential violator of patron privacy. Unmonitored in their efforts to protect their intellectual property without considering the rights of their customers, publishers could pose a threat to their customers' privacy, thus limiting their legal right of free access to information. Although encryption technology would appear to provide an answer to the confidentiality problem, it is not a panacea and that must be considered as the National Information Infrastructure is developed. Librarians need to stay alert to the developments in electronic publishing to be sure their concerns for patron privacy continue to be heard. 相似文献
