The relative contributions of expertise in search skills and domain knowledge were examined when using the Internet to find information. Four conditions were compared: expert searchers/high domain knowledge; expert searchers/low domain knowledge; novice searchers/high domain knowledge; and novice searchers/low domain knowledge. Search outcomes and verbal protocols were analyzed. The combination of search expertise and high domain knowledge yielded the most efficient searches. Higher search expertise yielded access to sites rated more accurate and credible. High domain knowledge yielded sites rated more thorough. Verbal protocols depicted searching as a complex decision process. Findings have implications for instructional support.  相似文献

The results of an analysis of the international flow of periodical and proceedings publications in different priority areas (the nanosystem industry and materials, information-telecommunication systems, rational wildlife management, and power and power conservation) and of critical technologies entering into them are presented. As the main sources of the information on foreign and Russian databases (SCOPUS, Current Contents. CSA, Ulrich’s Periodicals Directory, RZH VINITI, and the Russian Academy of Sciences) open scientific Internet resources were used. For correctness, a separate preparation of the terminological base of each subject area was made. Lists of publications on the detailed publishing and data about the availability of access to them on various Internet platforms were compiled as a result. The characteristics of the most important electronic resources for each area are given. The publishing houses and companies responsible for the major publications on the considered subjects not accessible at present to the Russian scientific community through widely known consortia (NEIKON and the Russian Federal Property Fund) are revealed.  相似文献

Background: To minimise retrieval bias, manual literature searches are a key part of the search process of any systematic review. Considering the need to have accurate information, valid results of the manual literature search are essential to ensure scientific standards; likewise efficient approaches that minimise the amount of personnel time required to conduct a manual literature search are of great interest. Objective: The objective of this project was to determine the validity and efficiency of a new manual search method that utilises the scopus ? database. Methods: We used the traditional manual search approach as the gold standard to determine the validity and efficiency of the proposed scopus method. Outcome measures included completeness of article detection and personnel time involved. Using both methods independently, we compared the results based on accuracy of the results, validity and time spent conducting the search, efficiency. Results: Regarding accuracy, the scopus method identified the same studies as the traditional approach indicating its validity. In terms of efficiency, using scopus led to a time saving of 62.5% compared with the traditional approach (3 h versus 8 h). Conclusions: The scopus method can significantly improve the efficiency of manual searches and thus of systematic reviews.  相似文献

Kaleida Health Libraries, in partnership with the Buffalo and Erie County Public Library, presented "Seniors Connect: A Health Information Project." The program was funded by the Community Foundation for Greater Buffalo and the Kaleida Health Foundation. The purpose of the project was to teach African-American and Hispanic senior citizens or their caregivers residing in the city of Buffalo how to search the Internet to find quality, accurate, understandable health information. Attendees were taught to distinguish quality information from inaccurate, misleading, and fraudulent material. A total of fourteen training sessions were offered. The Seniors Connect program was initiated with health fair at each branch library, conducted by Kaleida Health staff, to provide an opportunity for participants to learn about health care services available in their community; observe demonstrations of health information searches on the Internet; learn about new treatment modalities for diseases such as diabetes, high cholesterol, thyroid abnormalities, and hypertension; and interact with area health care providers and library staff. The sessions were highly rated by attendees and many participants expressed their gratitude for a program geared specifically toward seniors.  相似文献

Summary

This study examines the search tactics used by Web users to start their searches and deal with search problems such as too many postings and no relevant postings. Four search topics were developed to allow for comparison of search tactics used in four types of searches. The tactics analyzed include search statements, number of search statements, starting points, and tactics to solve the two search problems mentioned above. Search statements were searched in Alta Vista to determine their success and their nature was analyzed. With regard to the tactics used to address search problems, t-tests and chi-square tests found no difference between searches for texts and searches for graphic information, and between known-item searches and subject searches. Some of Web users' search tactics were similar to those for online searching or online catalog searches, but several tactics were unique to Web searching.  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 National Library of Medicine information access grant allowed for a collaborative project to provide computer resources in fourteen clinical practice sites that enabled health care professionals to access medical information via PubMed and the Internet. Health care professionals were taught how to access quality, cost-effective information that was user friendly and would result in improved patient care. Selected sites were located in medically underserved areas and received a computer, a printer, and, during year one, a fax machine. Participants were provided dial-up Internet service or were connected to the affiliated hospital's network. Clinicians were trained in how to search PubMed as a tool for practicing evidence-based medicine and to support clinical decision making. Health care providers were also taught how to find patient-education materials and continuing education programs and how to network with other professionals. Prior to the training, participants completed a questionnaire to assess their computer skills and familiarity with searching the Internet, MEDLINE, and other health-related databases. Responses indicated favorable changes in information-seeking behavior, including an increased frequency in conducting MEDLINE searches and Internet searches for work-related information.  相似文献

This study reports the results of a survey conducted at Aligarh Muslim University (AMU) to determine the extent to which Internet users are aware and make use of the Internet resources and services. The study examines the information searching behavior of Internet users. A questionnaire and follow-up interviews with the postgraduate students, research scholars and academic staff were conducted to collect data. A total of 489 questionnaires were distributed to the selected sample of eight faculties; 405 valid samples were collected. The data were analyzed according to the background of Internet users, Internet information searching behavior, use of Internet resources and services, quality of Internet information, problems of the Internet access and need for Internet literacy. The study found that the majority of respondents had a 5 year history of Internet access. The academic staff spent more time on the Internet than the students and research scholars. Although Internet search engines were the preferred information searching tool, other methods such as databases, gateways and World Wide Web (WWW) were also used. Online journals and databases were the preferred information sources among the Internet users. Respondents chose e-mail, WWW and search engines as important Internet services. About 60% of respondents believed that the good quality of information on the Internet made it a useful tool for education and research. Slow speed, lack of training and information overload were indicated as some of the factors affecting Internet usage. Further, recommendations are made to improve the use of Internet, including a well-planned Internet literacy program and preparation of subject gateways.  相似文献

Changes that are occurring in the information space of science are discussed. It is shown that global trends in this area, first of all the internetization of scientific communication and dissemination of open access to scientific publications, led to the occurrence of new methods of Scientometrics, namely, webometrics. Global and domestic webometric methods for creating indexes are described. The features of the Russian webometric index are listed. We conclude that the creation of a more complete and differentiated national index along with the world webometric index is advisable for adequate monitoring of the electronic resources of Russian science. Use of the experience of the Institute of Scientific and Educational Information of the Russian Academy of Education as a platform of the national experience index is proposed.  相似文献

OBJECTIVE: To evaluate the adequacy of the MEDLINE instruction routinely given to all entering medical students at the University of Miami School of Medicine and the ability of students to search effectively for and retrieve evidence-based information for clinical decision making by the end of their third-year. METHODOLOGY: The authors developed and implemented a strategy for evaluating the search strategies and articles selected by third-year students, who participated in the Objective Structured Clinical Examination (OSCE) in June 1996, 1997, and 1998, and reviewed the literature on evidence-based medicine and evaluation of medical student searches. RESULTS: A mean of 5% of the students' search strategies and a mean of 26% of articles selected were ranked "excellent" or "good"; a mean of 26% of search strategies were ranked "fair" and a mean of 69% were ranked "poor"; and a mean of 22% of articles selected were ranked "fair" and a mean of 52% were ranked "poor" based on the strategy developed to evaluate student searches. CONCLUSIONS: Evaluating medical student searches for evidence-based information is an effective way of evaluating students' searching proficiency, and, in turn, the adequacy of the instruction they receive. Based on the results of the OSCE test, the school of medicine expanded the library's educational role and the library implemented major changes in the training program. Information on evidence-based medicine is now incorporated into the MEDLINE instruction. Library faculty evaluate the required searches performed by students for evidence-based information during their first and second years; 30% of students are identified for follow-up, individualized instruction based on the evaluation; and a new case-based curriculum has been proposed with a fourteen-week problem-based learning (PBL) block. These developments are timely in light of the evidence-based competencies recently published by the Association of American Medical Colleges.  相似文献

OBJECTIVES: To explore library staff and health professionals' views on the effectiveness of information skills training and librarian mediated searching as methods of providing information for patient care. This is the second article describing the Effective Methods of Providing InfoRmation for patIent Care (EMPIRIC) project. The first paper, in a previous issue of this journal (Brettle et al. The costs and effectiveness of information skills training and mediated searching: quantitative results for the EMPIRIC project. Health Information and Libraries Journal 2006, 23, 239-247) describes the quantitative results. METHODS: A questionnaire survey to library staff and health professionals in the North West. Data was collected on perceptions of services, satisfaction and service usage. Statistical data were analysed using the Statistical Package for the Social Sciences (SPSS) and qualitative data using thematic analysis. RESULTS: Both information skills training and mediated searches are perceived by library staff and health professionals to be effective. There is strong support for mediated searches carried out on behalf of the health professional and information skills training to enable them to carry out their own searches. The results provide insights into the effectiveness of the services and the factors that make them effective. CONCLUSIONS: Evidence and stakeholders views support the provision of both information skills training and mediated search services. Both services are valued by users who see them as complementary methods of obtaining information depending on their needs at different times.  相似文献
