电子资源已成为高校读者利用图书馆的首要资源——图书馆电子资源利用情况调查及统计分析 总被引：1，自引：0，他引：1
本文根据“2008某高校学院图书馆电子资源利用情况读者问卷调查”结果进行分析,得出以下结论：电子资源已成为高校读者利用图书馆的首要资源。但真正达到最大化利用图书馆电子资源,使之更有效地为读者服务仍有一段距离。为此,图书馆今后的工作应以内涵建设为主,加强电子资源的宣传及读者检索技巧的培训工作,积极引导师生充分利用图书馆的已有的电子资源。 相似文献

数字资源获取对科学研究的影响—电子期刊全文下载与引用分析 总被引：4，自引：0，他引：4
根据中国科学院国家科学图书馆构建的数字资源环境,以化学领域的15种电子期刊为统计分析样本,分析2003-2005年的全文下载量。利用中国科学引文数据库中国科学院著者引用这15种期刊的引用数据,分析下载行为与引用行为相关的关系。通过数据的统计分析,可以看出数字资源对科学研究行为的影响:期刊全文的高下载量为持续状态;期刊下载行为与期刊引用行为的趋势基本一致;高下载量的期刊引用次数也比较高;下载量低的期刊引用量也比较低。以期刊下载量为自变量,期刊的引用量为因变量,进行线性相关分析。利用皮尔松Person相关系数公式计算证明了下载行为与引用行为存在正向相关关系。 相似文献

ABSTRACT Digital collections of full-text e-books are proliferating on the Web and provide a wealth of open content for students. To examine whether academic libraries are providing a digital gateway to these resources, ten e-book titles from open digital collections were searched in the online catalogs and Web pages of ten academic libraries serving distance learners. Only three of the digital collection e-books were available from any of the library catalogs, and none were found on library Web pages. Availability of the ten e-book titles through Google and other digital discovery tools also had mixed results. Continued projects for improved delivery of open online content are necessary. In order to fulfill their role as digital gateways for their academic communities, libraries must pursue metadata standards to support cross-searching, collaborative projects, and development of e-resource search software, which integrates with the library catalog. 相似文献

Availability studies are used to estimate the proportion of items in a library collection that are available to users, and the proportion of items in a library collection that are unavailable to users as a result of system and/or human errors. Sanjeet Mann of the Armacost Library at the University of Redlands used a series of availability studies to more accurately understand and troubleshoot the e-resources access errors that keep undergraduate students at the university from obtaining the full text of electronic resources. In this presentation, Mann shared the details of his process, his results, and the implications of those results for improving local search systems as well as a conceptual model of e-resource availability errors based on the results of his research. 相似文献

OBJECTIVES: Patterns of use of electronic versions of journals supplied by an academic health sciences library were examined to determine whether they differed from patterns of use among corresponding print titles and to relate the applicability of print collection development practices to an electronic environment. METHODS: Use data supplied by three major vendors of electronic journals were compared to reshelving data for corresponding print titles, impact factors, and presence on Brandon/Hill Lists. RESULTS: In collections where one-click access from a database record to the full text of articles was possible, electronic use correlated with print use across journal pairs. In both versions, Brandon/Hill titles were used more frequently than non-Brandon/Hill titles, use had modest correlations with journals' impact factors, and clinical use appeared to be higher than research use. Titles that had not been selected for the library's print collections, but which were bundled into publishers' packages, received little use compared to electronic titles also selected in print. CONCLUSIONS: Collection development practices based on quality and user needs can be applied with confidence to the electronic environment. Facilitating direct connections between citation databases and the corresponding journal articles regardless of platform or publisher will support scholarship and quality health care. 相似文献

Abstract Vendor-supplied e-resource statistics are often unavailable, unreliable, or not comparable across vendors. This study compared locally generated usage statistics to those supplied by four major publishers, and analyzed the resulting patterns of use. The additional information provided by vendor statistics was assessed to see how it might be utilized selectively to provide a better understanding of the importance of individual titles. The local statistics for all titles provided by the four publishers were then compared. A strong similarity between the two datasets was found, supporting the position that local statistics are a viable alternative to vendor statistics. Another finding was that the 80/20 rule is closer to 80/30 in the online environment. Some of the issues for subject librarians and electronic resources librarians are discussed. 相似文献

Neural Network Agents for Learning Semantic Text Classification 总被引：1，自引：0，他引：1
Stefan Wermter 《Information Retrieval》2000,3(2):87-103
The research project AgNeT develops Agents for Neural Text routing in the internet. Unrestricted potentially faulty text messages arrive at a certain delivery point (e.g. email address or world wide web address). These text messages are scanned and then distributed to one of several expert agents according to a certain task criterium. Possible specific scenarios within this framework include the learning of the routing of publication titles or news titles. In this paper we describe extensive experiments for semantic text routing based on classified library titles and newswire titles. This task is challenging since incoming messages may contain constructions which have not been anticipated. Therefore, the contributions of this research are in learning and generalizing neural architectures for the robust interpretation of potentially noisy unrestricted messages. Neural networks were developed and examined for this topic since they support robustness and learning in noisy unrestricted real-world texts. We describe and compare different sets of experiments. The first set of experiments tests a recurrent neural network for the task of library title classification. Then we describe a larger more difficult newswire classification task from information retrieval. The comparison of the examined models demonstrates that techniques from information retrieval integrated into recurrent plausibility networks performed well even under noise and for different corpora. 相似文献
