Investigation of end-user searching at the New York Hospital-Cornell University Medical Center (NYH-CUMC) revealed that 8% of the physicians surveyed were end users, 63% were interested in learning to search, and 29% were not interested. When training sessions were offered at the Burke Rehabilitation Center, an affiliated institution, 50% of the medical staff attended at least one class, but only 7% of the total staff became frequent searchers. Analysis of the precision and recall ratios of searches conducted by five end users at HYH-CUMC indicated that the best results were obtained by end users who had been taught to search by experienced librarian-searchers. The quality of end user searches did not appear to be affected by the "friendliness" of the systems used, the frequency of searching habits, or the length of time that an end user had been searching. 相似文献

The Alfred Taubman Medical Library at the University of Michigan has offered instruction in online literature searching to third-year pharmacy students as a component of the course "Drug Information and Scientific Literature Evaluation" since 1983. In the spring of 1989, a follow-up study was conducted to assess the impact of instruction on four classes of graduates. Of a pool of 151 graduates, 90 (60%) responded to a mailed questionnaire on their use of information and computerized literature searching. The respondents were divided into four subgroups: end-user searchers, users of intermediaries, end users who used intermediaries, and those who did not use computerized literature search systems. Seventy-two percent of the respondents used some type of computerized literature searching, and 42% performed their own searches. The four subgroups differed in general computer use, familiarity with MEDLINE search terminology, information use, reasons for using or not using literature searching, and characteristics of searches (i.e., type, time frame, amount, and frequency). Training in end-user search systems appears to have had an impact on the continued use of computerized literature searching several years after the formal educational program. 相似文献

This study compares the results of subject searching in two online catalog systems, one system with authority control, the other without. Transaction logs from Library A (no authority control) were analyzed to identify searching patterns of users; 885 searches were attempted, 351 (39.7%) by subject. One hundred forty- two (40.6%) of these subject searches were unsuccessful. Identical searches were performed in a comparable library that had authority control, Library B. Terms identified in "see" references at Library B were searched in Library A. One hundred five (73.9%) of the searches that appeared to fail would have retrieved at least one, and usually many, records if a link had been provided between the term chosen by the user and the term used by the system. 相似文献

Since 1970, Indiana University School of Medicine Library (IUSML) has traditionally been a high volume online searching institution. The library recently implemented an end user searching program which includes MEDLINE on CD-ROM. The effect of CD-ROM on online end user and mediated searching is discussed. Comparative statistics are provided by category of search service. CD-ROM has had a dramatic lowering effect on online end user searching and has had little effect on mediated searching. IUSML's experience with CD-ROM technology has been a positive one. Trained end users have become IUSML's greatest asset. 相似文献

This study analyzes the search behavior of end users who had taken a class in searching MEDLINE on the National Library of Medicine's MEDLARS system. Of the class alumni, 58% obtained passwords. Most of these were still conducting their own searches twelve to eighteen months later. Telephone interviews and search observations indicated that these end users were satisfied with their results and felt they had mastered the basic mechanics of searching. However, appropriate use of explodes and subheadings, as well as locating appropriate search terms, still presented difficulties for them. Further training in these areas may be required. 相似文献

The nature of bibliographic instruction in this hospital library continues to evolve. As the library makes easy-to-master, menu-driven tools for online searching available to end users, the demand for this service and the accompanying training increases. The demand for formal sessions covering research techniques is also increasing. Upon request, the library offered an extended research orientation to the housestaff in Obstetrics and Gynecology in May of 1993. An introduction to the use of CD-ROM was included to highlight its usefulness for citation verification, author searches, and for periodic current awareness searches on a particular topic. The UMH Library staff strive to offer the most current and comprehensive facilities and services to their users. These include automated access to the library's book, journal, and audiovisual holdings using the Data Trek system; online bibliographic searching by library staff and end users using CD Plus MEDLINE on CD-ROM and Grateful MED software; participation in clinical rounds to provide research support for clinical care; and several types of bibliographic instruction. In addition to the informal teaching of library research techniques that the library staff offers on a daily basis, the Library at Union Memorial Hospital is pleased to be able to provide a formalized and evolving bibliographic instruction program. 相似文献

MEDLINE (MEDLARS-ON-LINE) is the new on-line, interactive bibliographic searching system which was recently developed by the National Library of Medicine. The system provides users with lists of bibliographical citations and other information from a three-year file of over 1,250 biomedical journals. A survey testing user reactions was conducted at the University of Virginia Medical Library. The results of the survey are based on replies by 246 users who requested one or more MEDLINE searches between September 1972 and March 1973. The findings indicate that over 93% believe that MEDLINE is a substantial improvement over the traditional methods of searching through the printed indexes. These respondents also stated that the results of MEDLINE searches had assisted them in their clinical or research work, or both. Asked whether they would continue to use MEDLINE after the imposition of user charges on July 1, 1973, about 75% said that they would. The remaining 25% expressed some reservations and doubts. The survey gives reason to believe that with the imposition of user charges the use of MEDLINE will decline. 相似文献

The paper reviews the highlights of a four-week trial period (November 19-December 18, 1970) during which the Medical Library of the University of Virginia experimented with a new remote-access bibliographical control and retrieval system via its TWX machine. The system, called AIM-TWX, was sponsored by the Lister Hill National Center for Biomedical Communications and utilizes a timeshared IBM 360/67 computer in Santa Monica, California. Citations from 109 clinically-oriented journals from 1966 to date, including those currently included in the Abridged Index Medicus, may be retrieved either on- or off-line.Various aspects of this service are described, including problems of staffing, training, and record keeping, as well as the role of the MeSH vocabulary which is the principle "language" of the man-computer dialog.The statistical results indicated that the system was used for approximately 200 minutes on nineteen days and that an average of sixteen searches were run on any given day, or about 4.6 searches per hour of use. In spite of an inexperienced staff who had little knowledge of the MeSH vocabulary and whose training schedule was limited to one four-hour session, the experiment was highly successful in terms of searches and citations.At the end of the period, 298 searches had been run for 114 requestors, and 5,343 citations had been produced. Only fifty-five searches yielded no citations. The experiment generated a great deal of excitement and interest among the staff of the Library and of the Medical Center. Moreover, a large number of medical practitioners in large and small communities of Virginia participated in this experiment, indicating that there exists a great demand for this type of literature searching which AIM-TWX is able to provide with great rapidity. 相似文献

There is a current trend to make museum collections widely accessible by digitising cultural heritage collections for the Internet. The present study takes a user perspective and explores the characteristics of online museum visitors' web search behaviour. A combination of quantitative and qualitative methods was deployed in a case study at a National Museum of Military History. Quantitatively, data from a web questionnaire survey and a user study of interactive searching behaviour were collected and analysed. Qualitatively, observation protocols were coded and analysed based on inductive content analysis. It was found that metadata elements on factual object related information, provenience, and historic context was indicated to be relevant by the majority of the respondents, characterising the group of special interest museum visitors as information hungry. Further, four main characteristics of online museum visitors' searching behaviour were identified: (a) searching behaviour has a strong visual aspect, (b) topical searching is predominantly exploratory, (c) users apply broad known item searches, and (d) meaning making is central to the search process. 相似文献

A better understanding of users' search interactions in library search systems is key to improving the result ranking. By focusing on known-item searches (searches for an item already known) and search tactics, vast improvement can be made. To better understand user behaviour, we conducted four transaction-log studies, comprising more than 4.2 million search sessions from two German library search systems. Results show that most sessions are rather short; users tend to issue short queries and usually do not go beyond the first search engine result page (SERP). The most frequently used search tactic was the extension of a query (‘Exhaust’). Looking at the known-item searches, it becomes clear that this query type is of great importance. Between 38%–57% of all queries are known-item queries. Titles or title parts were the most frequent elements of these queries, either alone or in combination with the author's name. Unsuccessful known-item searches were often caused by items not available in the system. Results can be applied by libraries and library system vendors to improve their systems, as well as when designing new systems. Future research, in addition to log data, should also include background information on the usage, for example, through user surveys. 相似文献

The effect of introducing user fees on the frequency and quality of MEDLINE searching with GRATEFUL MED by physicians in clinical settings was tested. After training and free use (prior study), consenting participants were randomly allocated to pay searching costs (pay group) or continue without fees (no pay group). Fifty-nine physicians participated. Among the prior study's frequent searchers, the pay group searched at less than one third of the rate of those assigned to no pay. For less frequent searchers in the prior study, only 48% of those assigned to pay did any searches, compared with 85% for the no pay group (P = 0.006), and for those who did search, their frequency was almost half. However, there was no significant difference in the quality of searches; both groups demonstrated about equivalent recall (P = 0.77), but significantly lower precision (P = 0.03) than for the librarian's independent searches. Similarly, there was no difference in the proportion of searches affecting clinical decisions for the two groups. Thus, imposing user charges for online searching in clinical settings after a period of free use adversely affects searching quantity, but not quality. MEDLINE providers should consider whether user fees will undermine its benefits. 相似文献

Discovery tools offer users a powerful way of searching library holdings as well as external databases and indexes. They are becoming an increasingly common part of the library user experience, and research on the usability of such tools is expanding. In 2012, a mid-sized academic research library implemented Primo Discovery and Delivery by Ex Libris and conducted a diagnostic usability test to investigate how the tool is used without instruction, to discover patterns in searching behavior, and to uncover how compatible Primo is with user search behavior. This article will describe the design and implementation of the usability study. Despite some design flaws, users adapt to the tool over time and can perform effective searches. This article also provides recommendations for future usability studies in specific targeted areas where problems were detected. 相似文献

The problem of language in Web searching has been discussed primarily in the area of cross-language information retrieval (CLIR). However, much CLIR research centers on investigation of the effectiveness of automatic translation techniques. The case study reported here explored bilingual user behaviors, perceptions, and preferences with respect to the capability of the Web as a multilingual information resource. Twenty-eight bilingual academic users from Myongji University in Korea were recruited for the study. Findings show that the subjects did not use Web search engines as multilingual tools. For search queries, they selected a language that represents their information need most accurately depending on the types of information task rather than choosing their first language. Subjects expressed concerns about the accuracy of machine translation of scholarly terminologies and preferred to have user control over multilingual Web searches. 相似文献
