Summary As society has come to equate economic prosperity with the health of our living resources, national science policy has called for the development of a comprehensive digital knowledge base to support informed decision making and wise resource management. The Internet and World Wide Web demonstrate the earliest stages of this evolving virtual library of the natural world, offering an increasing array of high-quality, innovative resources and services in the natural science arena. This article discusses the leading providers of natural science information on the Internet and highlights some of the exemplary resources they are delivering online. The discussion concludes with a brief discussion of the role of the librarian in developing the Web of natural science knowledge online and provides a short Webliography of starting points for further exploration of this subject area. 相似文献

Summary A typology of information needs for political science allows academic librarians to match local and Internet resources with materials relevant to public users, non-major undergraduates, political science majors, graduate students, and professional political scientists. Recognizing public and non-specialist users, we may distinguish needs for information about politics from that which is specifically political science information. Second, the needs of majors, graduate students, and political science professionals often fall within the bounds created by the discipline's generally recognized subfields. Finally, as academics, graduate students and professionals have functional needs for information that helps them teach, publish, and participate in professional affairs. Because the number of potentially relevant topics is singularly broad and the literature of the discipline spans two and a half millennia, this article emphasizes gateway or directory Web sites appropriate to each type of information need. 相似文献

Abstract Access to biological information on the World Wide Web continues to grow at a rapid pace. Many resources that previously required a trip to the library are now accessible from the desktop PC. Three major categories of biology Web sites are explored: those with citation information, those functioning as clearinghouses or directories to other Web sites, and those that present biological information in innovative ways. The suggested Web sites are some of the best and may serve as models for future Web development. Many useful citation Web sites are fee-based and are likely to continue as such for the near future; MEDLINE and AGRICOLA are important exceptions. Many significant clearinghouse and information Web sites are not fee-based and allow innovative ways of finding and sharing information. The state of research information on the WWW is not developed enough for the researcher to forego using paper sources. 相似文献

Abstract Presently, eating disorders affect millions of people. Today, the media and the Internet are major publishing channels for consumer health information. Much research has found that the media may offer insufficient information on eating disorders. This research examines the quantity of adult consumer health publications on eating disorders in magazine articles and on the Internet in 1998 and investigates the effectiveness of Internet search engines. The results indicate that the resources found in popular magazines and on the Internet are not adequate, and that the Internet search engines are not effective in searching for information. 相似文献

面向网络信息资源聚合搜索的细粒度聚合单元元数据研究 总被引：1，自引：0，他引：1
由于相关信息片段分散分布在海量且复杂多样的网络信息资源中,用户往往需要花费大量时间浏览、查询和收集所需信息。面向聚合搜索的细粒度聚合单元元数据可以深入揭示信息特征及其关联关系,促进知识发现并提升知识服务效率。因此,有必要构建细粒度聚合单元的元数据描述框架。本文以图书情报领域开放获取期刊论文、在线百科、博客等网络信息资源为数据源,采用逻辑结构分析和形式结构分析方法建立聚合单元划分框架,包括篇章层级的标题、著者等外部特征,以及节段、句群、图表单元中的话语意图和语义功能等特征;通过分析聚合单元的属性特征及复用DC、LOM元数据元素,构建描述聚合单元访问信息、物理信息和语义信息的元数据框架;设计检索数据库并采用实验法对聚合单元元数据框架进行验证。实验表明,该元数据框架可支持多类型网络信息资源、各层级细粒度聚合单元的检索,可为细粒度信息聚合与搜索提供理论基础与实践指导。图7。表6。参考文献58。 相似文献

SUMMARY The sites reviewed in this article represent only a small fraction of the consumer health information sites available on the Web and are intended to be a starting point for locating authoritative, reliable health information. The first part of this article focuses on evaluation, since this is an important component of using information, particularly information located on the Internet. The second part of the paper reviews consumer-related Web sites arranged by categories:Comprehensive Sites; Directories/Portals;Government Sites; Association Sites; Drug Information; Alternative Medicine; Nutrition and Food Safety; and Other Health Issues. 相似文献

因特网的分析索引:乌托邦的梦想 总被引：3，自引：1，他引：2
检索互无关联的信息条目和数字内容时,所有查询因特网资源的方法都变得力不从心。本文通过研究现有的因特网查询方法、传统的书目控制和网站设计,探讨了对分析索引的需求问题。通过对这些索引的开发、设计和筛选过程中遇到的相关问题的讨论,得出一个结论,即在因特网上创建全面的分析索引不现实,而创建小型具体化的索引可能是查询某些具体数字信息的最佳途径。 相似文献

Summary Providing quality reference services is more challenging than ever. In addition to traditional print sources, the information professional now has a dazzling array of databases, both free and expensive, readily available. Internet reference service has evolved quickly over the last decade, moving from a place of last resort to a mainstream application. Librarians have responded in many innovative ways to connect their customers with information available on the Internet. However, superior Internet reference service requires substantial investments in equipment that administrators will have to consider. Staff and customer training have become pressing needs. Providing access to appropriate databases and materials will become increasingly challenging. 相似文献

Abstract As the World Wide Web continues to grow, the problem of locating quality resources becomes progressively more acute. While search engines can be invaluable tools for locating certain specific types of information, the technology is more limited in dealing with broad enquiries. This article outlines the development of the BUBL LINK / 5:15 service, which combines powerful browse and search options with a selective approach toresource discoveryand cataloging, and describes how the service overcomes some of the problems in locating Internet resources. 相似文献

AbstractThis article reports on a research project undertaken at a university in Iran to study the impact of academic libraries consortium on research productivity. The overall objective of study was to examine to what extent the subscribed resources meet the needs of users and to determine the quality of cited journals by researchers. It also examined the relationship between the access method to a cited journal, its quality and the average citing to it. The results of the present research can help decision makers for selecting and providing suitable resources and databases based on the users' needs. 相似文献

ABSTRACT In 1996 a team of researchers at the Alcohol Research Group (ARG) in Berkeley and the Addiction Research Foundation (ARF) in Toronto began a three year study of U.S. federal alcohol control policy. This paper draws on anecdotal evidence from the Policy Project to make a case study of the impact of Internet information resources on the development and adaptation of research strategies. We consider how Internet access affects utilization of information services within an organization; prospects and pitfalls in adapting research strategies to Internet resource availability; critical Internet resources for substance abuse policy analysis; and measures of utilization and effectiveness applicable to assessing the impact of Internet resources. 相似文献

SUMMARY This article examines the changing paradigms of reference librarianship as they relate to the study of Africa. It discusses important issues to do with the role of the reference librarian in assisting future scholarly research. Particular attention is given to how electronic resources are influencing the nature of Africana reference services and collection development. Given the problems faced in accessing information from Africa, emphasis is also placed on how partnerships between U.S. and African libraries and scholarly institutions can help improve information access in and about Africa. 相似文献

SUMMARY The quantity of legal and government information accessible through online delivery has increased tremendously. Information technology has revolutionized the way much of this information is disseminated by government and the way that researchers access it. The increase in publication can be attributed to two factors: the government's efforts to create a virtual depository of publications and the capability of Internet technology to provide personalized “feeds” of topic-specific information through Web logs and RSS news aggregators. In this article, finding tools, primary and secondary sources of legal and regulatory government information will be identified and described including search engines and guides. 相似文献
