基于DC的医学信息资源元数据比较分析

分析比较3种医学信息资源 metadata(MCM、CISMeF、EBM metadata)的格式、结构、编码语言等,探讨医学信息资源metadata应用开发等问题。     

Metadata:组织和发现Internet信息资源的数据

metadata是“关于数据的数据”,本文介绍了metadata的基本情况,并对HTML和XML环境的 几个metadata规范进行了论述（包括 Dublincore,PICS,Web Collections,CDF,MCF及RDF）。由于metadata 在Internet信息资源的组织和发现方面起着非常重要的作用,作者呼吁国人应当加强对metadata的研究。     

网络半结构化信息资源的描述

要对网络信息资源进行更好的管理和查询,首先要建立一种合理的信息资源描述机制。metadata是描述网络信息资源的有力工具,但新的信息描述机制--linking机制不仅能表述metadata的内容,而且可以表达比metada更丰富的语义,弥补metadata自身不能克服的一些缺陷。     

Metadata的涵义

本文从Webster字典对meta一词的释义出发，列举若干实例，总结metadata一词的涵义；同时就metadata一词的引伸意义作了阐释，并对“元搜索引擎”这种译法提出了不同观点。     

基于DC的医学资源元数据方案

介绍五种医学资源元数据方案：OhioLINK医学元数据、NLM Metadata Schema、 Medical Core Metadata（MCM）、CISMeF元数据、EBM metadata，分析比较他们的共性与区别，为制定我国的医学元数据方案提供思路。     

数字图书馆及其信息组织与检索浅识

探讨了数字图书馆的定义及特征，通过对当前网络信息组织与检索的关键技术－metadata和搜索引擎技术的分析，提出数字图书馆信息组织与检索存在的问题。     

元数据的具体功能探讨

元数据,英文名为“metadata”,作为一个科学术语最早出现在计算机信息技术领域,例如,在数据库系统中的数据词。目前在设计与创建信息资源系统的很多领域中,元数据已成为常用的重要术语。经济全球化、社会信息化使元数据在档案领域的应用得到增强。档案在各国政治、经济、文化等领域发挥的重要作用,一方面使电子档案飞速增加;另一方面使档案数字化突飞猛进。因此对元数据功能的认识和理解,有助于加快档案数字化建设。现就元数据具体功能作如下探讨。元数据是管理电子文件不可缺少的重要工具。在传统的档案库,没有检索工具,也能搜寻所需文件。…     

专题:21世纪图书馆学情报学的研究方向

元数据(metadata)是计算机可识读的关于数字化信息资源的信息,是关于数据的数据.因特网的发展要求对网络知识空间的信息进行组织、控制,元数据研究有利于形成自动化、高质量的网络搜索引擎,有利于网上信息存取和检索.元数据研究的侧重点是:①技术元数据,说明数字化信息资源的类型、存储格式和采用的技术标准;②权限元数据,说明信息资源的责任人或产权关系;③保存元数据,说明信息资源的存储位置,用统一数据定位符(URL)等来标志;④资源发现元数据,说明信息资源的类别、主题标志等;⑤元数据检索的工具和系统;⑥元数据的标准化问题.     

基于MDR的知识图谱语义关系及表示标准化模型研究

本文通过对国内外知识图谱标准化研究和发布情况的系统梳理与剖析,发现当前知识图谱标准化过程中缺乏对底层语义关系结构和表示的标准化。因此,本文首先在MDR (metadata registries)概念元模型的基础上,扩充了语义关系类型和关系表示,构建了一个标准的、可扩展的、通用的知识图谱语义关系元模型,为知识图谱中语义关系的构建提供了必备的语义要素,实现从传统数据语义结构向知识图谱语义结构的迁移。其次,为实现语义关系表示的标准化,以该标准化元模型为指导,构建知识图谱语义关系标准化本体栈,为知识图谱语义关系标准化提供了从语义关系结构到表示的标准构建体系。最后,以石油领域井下作业业务需求为背景,对其中涉及的语义关系进行注册,并据此实现了石油领域井下作业知识图谱中语义关系的标准化,验证了本文提出的知识图谱语义关系元模型的合理性和正确性,提出的知识图谱语义关系元模型具有创新性。

British Writings on Romania: From Travel Accounts to Studies

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.     

Slavic Approval Plans: What Works and What Doesn't

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.     

由“资源集聚”向“需求导向”转变——对武汉科技信息服务平台建设的思考

Politicking for the Public Library

ABSTRACT

In 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.     

Architectures of Knowledge and Literary Tradition: A History of the Almanac in Croatia

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.     

基于文献时间特征的学科主题演化分析方法研究 ——以图书情报学领域为例

How Digital Content Resellers are Impacting Trade Book Publishing

Some key questions for publishers in today’s market are: Could Amazon’s recent merger and acquisitions strategy create a disruptive or paradigm shifting business model in the publishing industry? Do their recent actions post mergers and acquisitions illustrate a predicable pattern of behaviour that publishers can strategize around? This paper will explore these questions and look at some of the possible reasons behind Amazon’s business practices and the possible consequences to publishers.     

Germany's New Culture of Welcome—Our Libraries are an Essential Part of it

ABSTRACT

German authorities are expecting more than 1 million refugees by the end of 2015. These people come to Germany to seek protection and assistance and to build a new life, therefore it is important to welcome them and to assist them in their integration as soon as possible. This situation creates a versatile and perfectly fitting opportunity for cultural and educational programs, including libraries, which can play a vital role in this integration process. The key to integration is the knowledge of the German language, and the most important challenge now is to teach the necessary language skills to as many asylum-seekers as possible.     

Syndicating Rich Bibliographic Metadata Using MODS and RSS

Abstract

Many libraries use RSS to syndicate information about their collections to users. A survey of 65 academic libraries revealed their most common use for RSS is to disseminate information about library holdings, such as lists of new acquisitions. Even though typical RSS feeds are ill suited to the task of carrying rich bibliographic metadata, great potential exists for developing applications that can exploit metadata exposed to Web services via RSS. Using the MODS metadata format, entire catalog records can be seamlessly embedded in RSS 2.0 feeds. Existing tools, such as Library of Congress Java toolkits and XSLT stylesheets, can facilitate this process, while a new XSLT stylesheet may be used to create the RSS feeds complete with MODS records. As an example of the added functionality these MODS/RSS feeds can offer, records from a MODS-enriched RSS feed can be ingested into a non-RSS application such as Zotero. As more emerging library technologies use Web services architectures to handle data objects, the ability to syndicate catalog records will become more critical to providing innovative library Web services.     

Device-Driven Research: The Impact of Chromebooks in American Schools

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.
