ABSTRACT

The authors of this article analyzed the differences in output when searching MEDLINE direct and MEDLINE via citation management software, EndNote X1®, EndNote Web®, and RefWorks©. Several searches were performed on Ovid MEDLINE and PubMed directly. These searches were compared against the same searches conducted in Ovid MEDLINE and PubMed using the search features in EndNote X1, EndNote Web, and RefWorks. Findings indicated that for in-depth research users, should search the databases directly rather than through the citation management software interface. The search results indicated it would be appropriate to search databases via citation management software for citation verification tasks and for cursory keyword searching.  相似文献

Summary

Digital reference is an important research area with the potential to enhance information delivery to library patrons. The process of digital reference involves the challenges and problems of an interactive computer-mediated reference interview. Related studies of mediated online searching have identified the major tasks during a mediated online search. The search intermediary's tasks included gathering information on the information need, previous searches on the topic by the information seeker, search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and the number of topics to be searched. The information seeker's tasks include providing information to the search intermediary on their topic, discussing their previous information seeking and evaluating the online search output. Models of digital reference interviews need to include more complex information seeking behaviors, such as successive searching and multitasking. Further research is needed to extend our understanding of digital reference processes.  相似文献

ABSTRACT

This article examined the search functions for all individual EAD Web sites listed on the Library of Congress Web site in 2003. In particular, the type of search engine, search modes, options for searching, search results display, search feedback, and other features of the search systems were studied. The data analysis suggests that there have been some improvements for EAD finding aids within Web sites, but also that problems persist. In addition, the functionality of search systems on Web sites varied considerably and the advantages of EAD finding aids for hierarchical searching have not been fully realized. The article also offers observations about cooperative EAD projects, the issue of search queries, and the relationship between Google and EAD Web sites.  相似文献

This article discusses some of the lesser known complexities of LEXlS and WESTLAW and the necessity for evaluating these systems critically. Sample searches highlight the major differences between WESTLAW'S and LEXIS's search protocols. Comparable features of each system are examined to show how users can improve the qualily of their search results and to warn of unintended consequences when users misapply them. Strategies for formulating searches that retrieve relevant cases and prevent the exclusion of potentially relevant cases are considered, along with the economics of online searching. Although the searches presented are limited to Ohio case law, they are adaptable for exploring the nuances of online searching in other state and federal jurisdictions.  相似文献

ABSTRACT

Search engine use is one of the most popular online activities. According to a recent OCLC report, nearly all students start their electronic research using a search engine instead of the library Web site. Instead of viewing search engines as competition, however, librarians at Binghamton University Libraries decided to employ search engine optimization strategies to make their Web site more visible on the search engine result pages. Although search engine optimization is used frequently by commercial Web sites, few libraries have attempted to optimize their own sites. This article describes Binghamton University's experiences in developing and implementing an optimization pilot project. The research presented in this article has importance for libraries who may be considering an optimization project for their own sites.  相似文献

ABSTRACT

In this study, students' use of a new educational Web portal was evaluated with particular emphasis on searching and browsing strategies. The effects and implications of a federated search system are also discussed. Fifty-four students, ranging from 5th to 12th grade, were given five tasks to complete using the SchoolRooms interface. The tasks required students to use both the search box and the categorical browse feature on the Web portal. Data collected were analyzed to determine time on task, rate of success and the subjects' awareness of success, and the type of search method chosen to complete the tasks. In general, students preferred the search-box strategy to the categorical-browse strategy, but exposure to both strategies resulted in increased use of the browse strategy. Success rates varied widely by task. Students had a difficult time distinguishing between various media and format types returned by the federated search. Results suggest that while students prefer a search-box strategy, it is by no means the only way they search for information. Students experienced difficulty in trying to de-aggregate the results of a federated search engine. These findings have implications for information literacy and library instruction. Forthcoming analysis of these data will address the factors related to search success.  相似文献

This study sought to better understand search performance using an online portal containing a collection of heterogeneous library resources for K-12 students. Search performance is examined in terms of search success, search time, strategy, and effort. This study revealed unsuccessful searches tended to take longer than successful searches; preference of search strategy (searching vs. browsing) did not affect search success outcome; students tended to perform well in tasks for which they were able to use various strategies, and unsuccessful searches tended to use more effort—more mouse clicks, more keystrokes, more queries, more sites visited, and more strategy shifts. Implications of the study are also discussed.  相似文献

Abstract

This study examines the promotion and knowledge of online patent literature search among students, librarians, and instructors to enhance university scientific output in Zanzibar. The study was guided by four key questions: What is the level of awareness of students, instructors and library staff about patent documents as source of information? To what extent do students and instructors access online patent databases? What is the library experience in training students about online patent literature searching?, and what are the challenges facing library and instructors in promoting patent literature search? The study used survey approach whereby questionnaire and interview were used to collect data. The recent literatures regarding online patent literature searching were also critically reviewed. A survey was conducted at two Universities in Zanzibar namely the State University of Zanzibar and Zanzibar University, whereby 20 library staff, 10 instructors and 140 undergraduate students from the School of Computing and the Faculty of Engineering were involved in this study. The findings show that more than three quarters of respondents were either partially aware or not aware at all about the existence of free online patent databases. Likewise, the majority of students had no enough skills of patent literature searching. However, usually the library organizes training on general online literature searching skills but patent literature searching was not effectively taught and a big challenge observed in this study regarding promotion of patent literature searching is inadequate patent searching skills among library and instructors. Based on the findings, the study proposed several recommendations to rectify the existing problem.  相似文献

Current online stores suffer from a cardinal problem. There are too many products to offer, and customers find themselves lost due to the vast selection. As opposed to traditional stores, there is little or no guidance that helps the customers as they search. In this paper, we propose a new approach for designing a successful personalized online store enabling the successful searching of customers in the store. This approach is based on algorithms commonly used in recommendation systems, but which are rarely used for searches in online stores. We employ this approach for both keyword and browse searches, and present an implementation of this approach. We compared several search guide algorithms experimentally, and the experiments' results show that the suggested algorithms are applicable to the domain of online stores.  相似文献

Searches with learning intent typically require the users to interact with the searching environment and perform knowledge acquisition features such as scan, read, and process the online content to fulfill their information needs. To capture indicators from searching behaviors that could account for the knowledge gained during a Web search, a qualitative study was performed using the Concurrent Think-Aloud protocol to observe the mechanisms of transfer and map knowledge flows during 78 search sessions. Findings indicate evidence of transfer of learning in the form of sixteen online information searching strategy indicators. This research aids the understanding of how knowledge is gained during search sessions and how to identify behaviors that could indicate that learning has occurred, which could be used to represent knowledge gain on Web search engines. In this way, it can aid search engines to become not only better tools of searching, but also tools of learning.  相似文献

This paper notes the interrelations between the types and methods of information searches, including Internet searches. It suggests the general approach for making a search for documents on the Internet, for example, scientific articles on information and communication. The methods for information searches used on the Internet are characterized with placing a particular emphasis on the method of searching with the use of search systems. General recommendations for successful conduction of searches are advanced to increase their efficiency. The goals and problems faced by a user during scientific information searches are presented. A user’s rights for the results of a search for scientific information are described from the standpoint of legal relations regulated by Russian legislation. Copyright protection methods are also considered based on Russian and foreign legislation.  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

This article summarizes the author's dissertation regarding search strategies of millennial undergraduate students in Web and library online information retrieval systems. Millennials bring a unique set of search characteristics and strategies to their research since they have never known a world without the Web. Through the use of search engines, they have come to expect that searches can be completed using an easy, single search box that produces complete articles on just about any topic. However, the reliability and quality of much of the information on the Web is questionable. Conversely, information that resides in library information retrieval systems is often of high scholarly content, but there is not a single, user-friendly system for millennials to use. A case study investigation was conducted at the State University of New York at Oswego, a public undergraduate university in Central New York. The goal of the study was to identify the search strategies of a sampling of millennial undergraduate students in both Web information retrieval systems and library information retrieval systems in order to expand upon existing theories about millennials and to suggest interface design enhancements, which could make online library information retrieval systems easier for millennials to use. The findings recommend improving database search functionality, such as natural-language searching, spell-checking, and uniform full-text wording and placement. Results also suggested that increasing the availability of full-text articles would contribute to millennials’ use of library information retrieval systems.  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

Abstract

Library Web pages are increasingly designed to be the initial entry point for research, whether used from the library or off campus. But the pages must be intuitive and easy to use or students may bypass them completely, in favor of more familiar Web resources. This article presents the process, results, and evaluation of a Web usability study conducted at Linfield College with undergraduate participants. Web usability testing was a relatively quick and inexpensive way to find out how students used the library Web pages, information that proved invaluable in making effective modifications to them. In the process, researchers gained insights into student online searching and research patterns that have informed reference and teaching activities as well.  相似文献

Use of online databases by humanities scholars searching as end users was monitored in a 2-year project conducted by the Getty Art History Information Program. Visiting Scholars at the Getty Center for the History of Art and the Humanities in Santa Monica, California, were offered the opportunity to do unlimited subsidized searching of DIALOG® databases. This third report from the project presents results of interviews conducted with the scholars regarding their experiences with searching, the role the searching took in their broader research activities, and their attitudes about the future of online searching in the humanities. Scholars found the experience stimulating and novel, with comments ranging from its “addictive” properties to a “Sorcerer's Apprentice” quality to complaints about the “industrialization of scholarship.” Generally, the scholars saw DIALOG searching as supplementing their usual research methods, and not changing them in a fundamental way. Online searching was seen as particularly useful for interdisciplinary research, and as possibly setting a new standard for the extent of literature that should be reviewed. Identified problems were about equally divided between difficulties with the search interface and lack of desired types of resources. All foresaw online searching being used in the future by arts and humanities scholars.  相似文献
