目前国外基于专利和期刊两类异种资源的集成数据预测科技发展趋势已成为重要的研究方向。由于集成数据库构建和分析的复杂性,国内还延续着专利、期刊数据的独立分析方法。为此,文章提出了基于专利和期刊两类异种信息资源的集成数据库构建方法,并对其应用进行了探讨。具体地说,文章分析了知名数据库提供商的专利和期刊的数据结构,从含义上选择了专利和期刊中相互匹配的字段,设计了两类异种数据信息资源的集成数据库,对该数据库的应用进行了概念分析。最后,给出了文章的结论及未来课题。 相似文献

An increasing number of users are reaching out to their academic library from their mobile devices to search for scholarly content. As a result, the resources offered through the library Web site should be equally accessible on all devices. Database content is a critical library resource, and vendor products must evolve to function effectively on all types of devices. This study examined 197 databases at Adelphi University Libraries to determine if they are universally accessible either through the provision of an app or a mobile-optimized Web site. The study concluded that the majority of vendor platforms are not optimized for viewing across smart devices. These findings indicate that libraries should encourage vendors to offer mobile-optimized databases, and desktop computers may still be necessary for database searching. 相似文献

CALIS is a nationwide academic library consortium in China. By coordinating, guiding, and organizing academic libraries, CALIS aims to minimize spending while obtaining foreign resources with the best prices and services. It also aims to meet the demands of teaching and research via the CALIS cooperative purchase service. Since 2005, there has been a customer satisfaction survey to evaluate this cooperative purchase service and the databases subscribed to by the CALIS consortium during the CALIS annual “imported database training week”. 494 staff members from 246 libraries took part in the fourth such survey to evaluate 87 databases cooperatively purchased in 2009. According to the survey, CALIS releases database usage reports and database evaluation rankings to help libraries analysis costs and make more informed collection developments decisions. Such survey activities provide a win–win situation, not only for CALIS and its member libraries, but also for database vendors. Survey results and usage reports help libraries analyze the quality of resources and provide evidence for libraries to choose among different purchasing options. Also, more promotional work has been done to enhance understanding, solve libraries' problems, and improve service quality. Finally, survey results and database evaluation rankings have been used to urge database vendors and publishers to make improvements relevant to libraries' development strategies. 相似文献

ABSTRACT Based on his experience, the author summarizes what reference/collection development librarians and library users want and expect from aggregator databases, and what's needed from database vendors and from librarians to meet these expectations. Particularly important are content quality, reliability, modularity, and affordability, interface simplicity and flexibility, and reliable congruence between and integration of print and electronic editions. From vendors, librarians should demand more and better content guarantees, purchase options, communication of content details and changes, full-text searching, and persistent URLs for individual titles. Librarians should provide analyzed cataloging and holdings for all titles in aggregator databases, keep these records current, fully integrate them with records for print and other electronic editions, and incorporate them into web catalogs, in addition to providing other web access tools such as browsable title lists. 相似文献

Abstract A review of the help files in several major databases revealed that database vendors have begun including information on citing sources, which has the potential to be very useful to students. Surprisingly, 94% of the citation examples in the databases reviewed had errors. The average number of errors per example was 4.3. The citation help appears to have been put together quickly, with little thought and no proofreading. Librarians must insist that vendors correct or remove this information. 相似文献

[目的/意义]通过调查研究,探索适合国内图书馆具有可操作性的数字资源使用统计方法,以期提高数据的准确性和可比性,支持数据资源采购、管理与服务。[方法/过程]通过问卷、访谈等方式调查了15家知名的中文数据库商,分析其数字资源使用统计的现状、问题和需求。[结果/结论]发现仅同方知网一家通过COUNTER审核,4家遵循国内相关标准;仅同方知网能提供统计平台和日志信息;但统计功能均不够完善;统计指标不规范;使用统计数据应用广泛,且普遍认为其准确、规范性对于图书馆和数据库商双方均非常重要。为规范中文数据库使用统计,建议推动中文数据库商遵循COUNTER标准,利用SUSHI统一收割使用统计数据,深化统计平台功能。 相似文献

《Library Acquisitions: Practice & Theory #》1993,17(1):53-59
The past decade has brought many changes in the relationships between librarians and vendors and in the ethics between them. Foremost among these changes have been the advances in library technology and automation. In the past, the symbiotic relationship between librarians and vendors was relatively simple. Librarians wanted a vendor who could supply library materials efficiently, accurately, and with a good discount. The vendor was expected to be knowledgeable about library trends and needs and to be the party with the business savvy and sophistication to work with publishers. Now, not only do librarians expect vendors to supply materials efficiently and accurately, they also expect technological sophistication in the providing of these materials, automated systems, and service for the systems. This is especially true for the acquisition of serial publications and the needs of automated services such as check-in, claiming, ordering, and invoicing. Librarians now want more than just materials at a reasonable price. They want automated systems and databases for acquiring materials, managing budgets, and servicing collections. This paper will review the historical relationship of the ethics between vendors and librarians. It will explore the information and automation society and how the decline of business ethics in the eighties changed this relationship. 相似文献
