ABSTRACT Web-scale discovery services promise fast, easy searching from a single Google-like box, pleasing users and making library resources more discoverable. Some librarians embrace the concept of giving users what they have come to expect from Google, while others are concerned that this will “dumb down” searching and undermine information literacy. In this article we explore the potential impact of Web-scale discovery tools on information literacy, focusing particularly on undergraduate research skills. We review the existing literature and present findings and experiences from two mid-sized academic libraries that have adopted EBSCO Discovery Service as their library home page portal. 相似文献

Academic law libraries now have access to many Dialog databases through the transparent interface of Westlaw. This is available at a moderate charge under the academic contract with West. Many of these databases are of special interest to librarians, and are being underutilized. This paper surveys some available databases with special library uses, and notes special aspects of searching the Dialog databases through the Westlaw interface. 相似文献

Funds made available at the close of the 2010–11 fiscal year allowed purchase of the EBSCO Discovery Service (EDS) for a year-long trial. The appeal of this web-scale discovery product that offers a Google-like interface to library resources was counter-balanced by concerns about quality of search results in an academic health science setting and the challenge of configuring an interface that serves the needs of a diverse group of library users. After initial configuration, usability testing with library users revealed the need for further work before general release. Of greatest concern were continuing issues with the relevance of items retrieved, appropriateness of system-supplied facet terms, and user difficulties with navigating the interface. EBSCO has worked with the library to better understand and identify problems and solutions. External roll-out to users occurred in June 2012. 相似文献

面向LOD的关联发现过程的定位、目标与复杂性分析 总被引:1,自引:1,他引:0
本文以关联数据应用过程中的关联发现过程为研究对象,分析了面向关联开放数据(LOD)的关联发现过程的定位、目标与复杂性。本文认为,关联发现过程处于关联数据应用过程三阶段(数据发布、数据互联与数据消费)中的第二阶段。关联发现过程的整体目标是构建多类资源之间的关联数据网络,该过程的本质就是关联数据网络不断演变的过程。关联发现的过程具有多任务、多路径、多步骤等复杂性特征。目前流行的关联发现框架还存在缺乏对整个网络演变过程的支持、任务类型单一、缺乏流水线机制等不足。因此,关联发现技术的研究急需新的面向整个关联数据网络的、支持完整演变过程的、支持多任务集成的理论、方法与框架。图5。表1。参考文献17。 相似文献

Web-scale discovery systems are gaining momentum among academic libraries as libraries seek a means to provide their users with a one-stop searching experience. Illinois State University's Milner Library found itself in the unique position of having access to two distinct discovery products, EBSCO Discovery Service and Serials Solutions’ Summon. Two researchers at Milner conducted a usability study for the former product in 2010, and now two other researchers, including one involved with the EBSCO Discovery Service study, have conducted the same study on the latter product. The goals of the study were twofold: first, to identify user behavior while using discovery systems’ search features and to see whether using these features would improve the user's searching experience, and second, to compare user experiences with EBSCO Discovery Service and Summon at Illinois State University. The similarities and differences in user expectations, use, manipulation, and satisfaction with both discovery tools are explored in this article, with the ancillary hope that libraries investigating discovery tools might be able to make a more thoroughly informed choice in acquiring their own Web-scale discovery system. 相似文献

Web-scale discovery service systems and platforms are continuing to evolve and become more commonly adopted in academic libraries. Functioning as more than next-generation catalogs due to their volume and associated Web services, they invite strategic inquiry and launch libraries into deeper questioning and continuous critical thinking concerning discovery system best practices. This article explores emerging library discovery positions and discovery requirements gleaned through position postings from Autocat, Code4Lib, ERIL-L, and NGC4Lib listserv e-mails, from February 2012 through July 2014, along with a 2013 scan of Association of Research Library (ARL) staff directories’ Web sites. As seen through the lens of recent discovery position postings and names of discovery positions at ARL libraries, staffing solutions suggest strategic oversight and deep understanding of discovery systems, metadata, and users. This study of 36 discovery positions reveals directors or managers as comprising the highest number with ten (28 percent), systems with eight (22 percent), cataloging and metadata with seven (19 percent), acquisitions or electronic resources with five (14 percent), user experiences with three (8 percent), access services with two (6 percent), and general technical services with one (3 percent). These emerging discovery positions traverse both traditional technical and public services functions, with the majority, 26 (72 percent), from large research-level institutions. 相似文献

The intent of this investigation was to learn what factors may have contributed to low usage of a small set of reputable open access scholarly journals, as evidenced in graduate student reference lists. Inquiry into differences among open access sources referenced between 2005 and 2014 revealed that non-indexed journals were being used notably fewer times than their commercially indexed counterparts. A comparison of HTML source code between indexed and non-indexed journals illustrated that certain metadata and other coding features may have affected the visibility of non-indexed journal content. The study suggests to librarians the presence of less visible empirical literature on the web and to smaller, independent academic publishers, the need to apply better quality metadata and optimization strategies to their open access journal content. 相似文献
