E-mail-alerting system of online databases is a new trend catching up fast with researchers. Results of auto-run set queries are informed through e-mails as ‘alerts’ to the registered user. Even though e-mail-alerting systems are quite popular amongst Internet users, their inherent advantages remain unexplored in the Indian scenario. An effort to explore all such features available in the ScienceDirect online database has been made in this paper. The process of registration for activating e-mail alerts, customizing a home page, selecting favorite journals, search alerts, journal issue alerts, citation alerts and search history are briefed with screen shot examples. The study emphasizes the fact that librarians and information Science professionals should take lead roles in unveiling all such possible features available in various online databases. They should also make efforts at informing the user community of the utility of such features in a bid to enhance the research output.  相似文献

End-user search software is designed to simplify online searching for the casual searcher. User-friendly features provide relatively easy online access to remote databases without the need for expert search systems. At issue is whether the simplified features of such software compromise what is potentially retrievable, and if so, whether the missing information is critical to the end user. A study was designed to address this question, particularly as applied to clinicians using a user-friendly search software package such as Grateful Med. Clinician participants compared their Grateful Med search results with a full Elhill search (as performed by an intermediary) and indicated whether references unique to either search were or were not critical to their information needs.  相似文献

Abstract

Since early 1995, the University of Nevada, Reno (UNR) libraries have offered its user community a new and enhanced service through the InfoTrac SearchBank from Information Access Company (1AC). Available through the libraries' online catalog, this service offers useful features like remote access through the Internet, indexing and abstracting, fall-text access to 460 journal titles, as well as a powerful search engine. The service also provides access to a family of databases in areas such as, general reference, health, business and law information. The purpose of this article is to familiarize the business librarians and researchers with the business databases (General BusinessFile ASAP and Businesslndex Backfile) available through the InfoTrac SearchBank service.  相似文献

The MELVYL MEDLINE project resulted in the addition of a full five-year subset of MEDLINE to the University of California's (UC) MELVYL online union catalog. As one of the nation's largest MEDLINE end-user searching systems, MELVYL MEDLINE provides online bibliographic access to the biomedical journal literature for all UC personnel at over seventy library sites or by remote access. This paper summarizes the project's accomplishments, reports MELVYL MEDLINE use and its impact on library services, and provides insights for other end-user search systems. The project serves as a model for adding databases to the MELVYL catalog and demonstrates the potential for use by other disciplines of a specialized database when readily accessible. Evaluation results report high user satisfaction and high usage. However, many advanced searching features of the interface are little used by searchers. Effects on library services include marked increases in reference transactions and interlibrary loans, with significant declines in mediated search services. Future MELVYL MEDLINE enhancements include matching search retrievals to journal locations, linkage to an online document delivery system, and consideration of building a superset of databases by combining MELVYL MEDLINE with citations from another database in the MELVYL catalog.  相似文献

The argument that mediated online ready reference searching is an indispensable service is presented. The proliferation of Internet resources, including electronic journals, online catalogs, and other resources creates new user expectations and demands on reference service points. While end-user searching makes sense when a common interface for a multitude of diverse databases is provided, the contemporary version of remote access challenges searchers to tackle nearly every type of vendor product available as well as several homegrown varieties. Until "intelligent systems" can span the diversity of available online systems, librarians may once again find themselves in the role of search mediator that was common when online databases were first introduced while the task of keeping reference librarians apprised of developing electronic resources is formidable, end-user instruction is even more so. Because the diversity of online systems makes it impractical to know each system in very much detail, reference librarians will need to concentrate on developing a better conceptual framework.  相似文献

BioSYNTHESIS is a prototype intelligent retrieval system under development as part of the IAIMS project at Georgetown University. The aim is to create an integrated system that can retrieve information located on disparate computer systems. The project work has been divided in two phases: BioSYNTHESIS I, development of a single menu to access various databases which reside on different computers; and BioSYNTHESIS II, development of a search component that facilitates complex searching for the user. BioSYNTHESIS II will accept a user's query and conduct a search for appropriate information in the IAIMS databases at Georgetown. For information not available at Georgetown, such as full text, it will access selected remote systems and translate the search query as appropriate for the target system. The search through various computer systems and different databases with unique storage and retrieval structures will be transparent to the user. BioSYNTHESIS I is complete and available to users. The design work for BioSYNTHESIS II is under development and will continue as a multiyear technical research effort of the proposed Georgetown IAIMS implementation project.  相似文献

The rapid increase of smartphone usage in recent years has provided students the opportunity to participate in mobile learning (m-learning) anywhere, anytime. Academic institutions are also following this trend to launch many m-learning services. This article investigates the differences of the user needs between undergraduate (UG) and postgraduate (PG) students though an online survey with 140 Library Information Systems (LIS) subjects in a Japanese university in order to provide solid foundations for future m-learning studies. We find that UG and PG students do not show significant differences in adopting m-learning by smartphones despite the fact that they have different learning patterns. The m-learning frequencies of smartphones generally range from weekly to monthly, where using search engines is the most frequent, and reading academic resources is the least frequent. They tend to use these services for handling their daily routines (such as search engine, social networks) rather than their academic activities (such as using online databases to search for academic materials). Further, the results also show that content displaying issues (e.g., small display screen, text unable to enlarge) are barriers for most subjects in using these m-learning services.  相似文献

The University of North Texas Libraries provide extensive online access to academic journals through major vendor databases. As illustrated by interlibrary loan borrowing requests for items held in our databases, patrons often have difficulty navigating the available resources. In this study, the Interlibrary Loan staff used data gathered from the ILLiad interlibrary loan management system to investigate why patrons request locally available materials. This study resulted in recommendations for the Libraries' linking strategies in EBSCOhost databases. Several user education needs were identified and communicated to the Libraries' Subject Liaisons.  相似文献

Two-stage statistical language models for text database selection   总被引:2,自引:0,他引:2  
As the number and diversity of distributed Web databases on the Internet exponentially increase, it is difficult for user to know which databases are appropriate to search. Given database language models that describe the content of each database, database selection services can provide assistance in locating databases relevant to the information needs of users. In this paper, we propose a database selection approach based on statistical language modeling. The basic idea behind the approach is that, for databases that are categorized into a topic hierarchy, individual language models are estimated at different search stages, and then the databases are ranked by the similarity to the query according to the estimated language model. Two-stage smoothed language models are presented to circumvent inaccuracy due to word sparseness. Experimental results demonstrate that such a language modeling approach is competitive with current state-of-the-art database selection approaches.  相似文献

This current survey examines the status of multidatabase use by reference personnel responsible for online searching in academic libraries. The study surveyed 200 college and university libraries in the United States with a graduate program in psychology. The results indicate that 90% of database searchers do not restrict their online searches of psychological topics to PsycINFO. Some of the databases that were identified as adjuncts in performing a multidatabase strategy were: ERIC, MEDLINE, SOCIAL SCISEARCH and SOCIOLOGICAL ABSTRACTS. A few respondents indicated using multi-file options such as DIALOG'S DIALINDEX. The current findings suggest that online searchers need to be cognizant of the advantages of multidatabase searching in a designated discipline, and should inform end-users of the availability of such comprehensive search options.  相似文献

This article provides an overview of selected Web-based resources containing grey literature in the area of communication disorders. It is geared to practitioners, researchers, students, and consumers seeking reliable, freely available scientific information. Grey (or gray) literature has been defined as "that which is produced on all levels of government, academics, business, and industry in print and electronic formats, but which is not controlled by commercial publishers."1 This paper reviews various general reference sources potentially containing grey literature on communication disorders. This review includes identification of the methods specialists in this field use to obtain this valuable, yet often overlooked, literature. Access points and search tools for identifying grey literature on communication disorders are recommended. Commercial databases containing grey literature are not included. Conclusions presented in this article are considered complementary to traditionally published information resources on communication disorders, such as scholarly journals, online databases, etc.  相似文献

Increasingly we hear of "electronic publishing" in the form of books and journals made available as databases, either through traditional online services or through electronic message services. This paper explores its potential impact on the medical library community and on the relationship between end user and librarian. The librarian's new roles as intermediary, facilitator, and advocate for end users are examined. The question of developing expertise for evaluating information as well as facilitating access is addressed.  相似文献
