学术数据库的利用分析   总被引:7,自引:0,他引:7  
近些年来,由CALIS牵头组织的中国大学集团共引进了24个学术数据库。这些数据库的引进为各学校的教学和科研活动的开展起到积极的文献保障作用,但是如果不能对数据库的利用情况进行有效的分析和评价,则无法确切地知道数据库的使用状况,甚至给学校的财政带来浪费。本文将以全文数据库Elsevier ScienceDirect OnSite在东南大学使用情况为例,探讨文献资源对东南大学重点学科的满足度、用户所在学科分布和下载文献的时间分布,数据库的购置成本和效益分析等,以期望提高学术数据库的利用水平。  相似文献

GAP理论模型在数字资源绩效评价中的应用   总被引:1,自引:1,他引:0  
选择湖北民族学院图书馆2008年以来使用三年以上的4个典型全文数据库(CNKI、VIP、SDOS、SDL)作为研究对象,建立SERVQUAL和LibQUAL+TM模型,依据绩效值与下载成本、用户期望、用户感知等相关性,导出绩效值定义与计算公式,并分析其重要影响因子。结果发现,SDOS单篇下载成本是1.86元,是集团单篇下载成本(0.7元)的2.5倍,位居首位。SDL单篇下载成本是0.16元,是集团单篇下载成本(0.10元)的1.5倍,位居第二;专家组的绩效值SDL最高,用户组的绩效值CNKI最高(P<0.05),两者平均,以SDOS为最低(P<0.05)。研究表明,绩效值定义与计算公式经过4个典型全文数据库的验证与应用,理论绩效值与实际绩效值具有一致性和可操作性,具有实际应用价值。  相似文献

In the era of digital libraries, Web-based electronic databases have become important resources for education and research, providing functionality and ease of use superior to print products. Analysis of usage of such online systems can provide valuable information on user behavior, and on usage of electronic information in general. Furthermore, the findings can be used to improve effectiveness of these electronic systems and identify areas for improvement, ranging from user interface and functionality to documentation and product training. This article analyzes usage of the Taiwan-based ScienceDirect OnSite E-journal system, one of the largest and most heavily used full-text Science, Technology, and Medicine (STM) databases worldwide.  相似文献

An exploratory study to investigate perceived differences between searching full-text databases and bibliographic databases was undertaken. BRS's full-text database, Comprehensive Core Medical Library (CCML), and BRS's current MEDLINE file (MESH) were compared. Identical literature search topics were run in the two databases and the results evaluated regarding currency of search results, success in answering specific questions, uniqueness of information retrieved, and relevancy of retrieval. Additionally, connect time and costs were noted to aid in determining the feasibility of offering full-text database searching as a service for which the authors' institution would charge.  相似文献

Background: The researchers involved in this study work at Exeter Health library and at the Complementary Medicine Unit, Peninsula School of Medicine and Dentistry (PCMD). Within this collaborative environment it is possible to access the electronic resources of three institutions. This includes access to amed and other databases using different interfaces. Objectives: The aim of this study was to investigate whether searching different interfaces to the amed allied health and complementary medicine database produced the same results when using identical search terms. Methods: The following Internet‐based amed interfaces were searched: DIALOG DataStar; EBSCOhost and OVID SP_UI01.00.02. Search results from all three databases were saved in an endnote database to facilitate analysis. A checklist was also compiled comparing interface features. Results: In our initial search, DIALOG returned 29 hits, OVID 14 and Ebsco 8. If we assume that DIALOG returned 100% of potential hits, OVID initially returned only 48% of hits and EBSCOhost only 28%. In our search, a researcher using the Ebsco interface to carry out a simple search on amed would miss over 70% of possible search hits. Subsequent EBSCOhost searches on different subjects failed to find between 21 and 86% of the hits retrieved using the same keywords via DIALOG DataStar. In two cases, the simple EBSCOhost search failed to find any of the results found via DIALOG DataStar. Conclusions: Depending on the interface, the number of hits retrieved from the same database with the same simple search can vary dramatically. Some simple searches fail to retrieve a substantial percentage of citations. This may result in an uninformed literature review, research funding application or treatment intervention. In addition to ensuring that keywords, spelling and medical subject headings (MeSH) accurately reflect the nature of the search, database users should include wildcards and truncation and adapt their search strategy substantially to retrieve the maximum number of appropriate citations possible. Librarians should be aware of these differences when making purchasing decisions, carrying out literature searches and planning user education.  相似文献

美国过刊数据库概况及对我国开发过刊数据库的思考   总被引:7,自引:0,他引:7  
20世纪末,美国开始出现过刊数据库,例如JSTOR、Wilson公司期刊文献回溯数据库、 MUSE项目及期刊题录索引等。国内目前尚没有1989年之前的过刊回溯数据库。在国内建设 过刊数据库具有减小馆藏压力、挽救过刊、优化服务等重要意义。建设过刊数据库既有不利因 素,也有可操作性。参考文献8。  相似文献

A survey to determine attitudes toward end-user searching was made at Loyola University's Medical Center Library using MEDIS, an online full-text and bibliographic medical retrieval system. One hundred forty-one completed questionnaires were analyzed for this report. Information was collected on user familiarity with computers, end-user training, system use, mechanics of searching, and attitudes toward future use. Computer familiarity was highest among the faculty users. Ninety percent of the respondents saw librarians as a crucial agent in training and in providing end-user assistance. Respondents identified five major reasons for using the system: helpfulness, convenience, time savings, rapid feedback, and presentation of needed information. Searching the MEDLINE database rather than the full-text database was the search method of choice. Continued use of both mediated and end-user searching was intended by most of the respondents. Survey results support a perceived need for end-user searching and confirmed recommendations of the Association of American Medical Colleges on medical information science skills.  相似文献
