Purpose – One of the most effective ways information retrieval (IR) systems including Web search engines can improve relevance performance is to provide their users with tools for facilitating query expansion. Search engines such as Google provide users with keyword suggest tools. This paper aims to investigate users’ criteria in relevance judgment regarding Google’s keywords suggest tool and to see how such keywords would lead to more relevant results from the viewpoint of users. Design/methodology/approach – Through a mixed method approach, quantitative and qualitative data were collected from 60 postgraduate students at Ferdowsi University of Mashhad, Iran, using four different instruments (questionnaire, thinking aloud technique, query logs and interviews). Findings – Among other criteria, the “relation between suggested keywords and the information need” (with the mean rate of 3.53 of four) was considered the most important by searchers in selecting suggested keywords for query expansion. Also, the “relation between suggested Keywords and the retrieved items” (with the mean rate of 3.62) was considered the second most important criterion in judging the relevance of the retrieved results. The participants agreed that the suggested keywords by Google improved the retrieval relevance. The content analysis of the participants’ aloud-thinking sessions and the interviews approved such findings. Originality/value – This research makes a contribution to the need of designers of IR systems regarding the use of add words for query expansion. It also helps librarians how to instruct searchers with expanding their queries to retrieve more relevant results. Another contribution of the study is the identification of a number of new relevance judgment criteria for Web-based environments.
During the COVID-19 pandemic, modern science demonstrated its ability to respond well to the health crisis by publishing useful and reliable information. This disease has also led to an increase in psychological publications in this field. However, most scientometric studies have focused on medical aspects, and social science research has been neglected. Therefore, to fill this research gap, we analyzed the research on COVID-19 in the field of psychology to provide an insight into the perspective, research fields, and international collaborations. Data were collected from the Web of Science database and analyzed using Citespace and Bibliometrix (Biblioshiny). The overall performance of the documents was described, and then keyword co-occurrence and co-authorship networks were visualized. Fifteen main clusters were formed by drawing document co-citation network. The result indicates that Anxiety, mental health, delirium, loneliness , and suicide were important topics for researchers. Considering the special conditions that COVID-19 created for human societies, perhaps one of the most important subjects in the field of health is psychological studies. Using the results of this study, psychology researchers can identify their potential colleagues and research gaps in the subject of Covid-19.
Background and aims:Effective information search and access to the right information at the right time, has become one of the ideals medical purposes for physicians. If for any reason physicians do not get an immediate response and appropriate to their clinical questions, a big problem and serious fault in various processes including diagnosis and treatment in health care happen. Medical librarian or Information professionals are expert in the acquisition, integration, and implementation of updated and reliable information and can help to solve this problem. Thus, the present study investigates a fundamental solution in this context to solve the problem by using and enjoyment of the medical librarian in teaching expertise.Methods:This was a descriptive study. Training how to do effective search to access information in the frame of workshop to fourth-year medical students in the Persian Gulf hospitals set a timetable (one month), 8 sessions and per section took an hour and a half meeting held. In order to assess the training, the students were taken pre-test and post-test. The sample size of 57which included the entering medical students of 2013 who had recently entered to clinical stage of treatment. Students randomly assigned to the Intervention group included 29 and control group 28. Information gathered through the Self-administered questionnaire and its validity and reliability have been highlighted by 10 professors of library and information field. Data analysis was performed using statistical software SPSS16.Results:The results were determined by using chi-square test shown the student satisfaction after attending a workshop and 90 percent of the physician evaluated medical librarians useful to provide updated information on evidence-based medicine.Conclusion:Training students who have recently entered to the clinical stage, for doing effective search on evidence-based medical information in order to meet the needs of the medical community and reduce medical errors that occur in clinical practice, is necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
