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

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

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

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
