This study investigated the quality and clarity of health information from a total of 238 (126 English and 112 Chinese) answers retrieved from Yahoo!Answers sites. Registered nurses and library professionals judged information quality based on 8 criteria: accuracy, completeness, relevance, readability, verifiability, professional advice, usefulness and non-commercialization. Writing clarity was assessed through rhetorical structure analysis. Results showed that 46% of answers were of poor quality. Furthermore, many Q&A site users were unable to distinguish adequately between high- and low-quality answers. Only 60% of their selected best-answers corresponded to those of the health professionals. These results indicate that the reliability of health information on Q&A sites is questionable. This unreliability may partially be due to the fact that Q&A site answers contain both medical information and social support. Although both are important, they are not always compatible. It may even be dangerous to mistakenly present social support as objective medical information. This research suggests that medical advice and social support should be separated. This has a further advantage in that medical advice could be subjected to stringent, necessary quality assurance measures, without interfering with social support. 相似文献

Public librarians in South Korea assist users in obtaining information on a variety of topics. However, health-related information and services have a lower profile than other services due to a perceived lack of librarian expertise in searching and evaluating health resources. Although public library users are actively seeking health information, it has become critical for both public librarians and users to develop skills for using and evaluating Internet health resources. Therefore, this study was conducted to identify a set of useful criteria to evaluate online health web sites for both librarians and library users. From a comprehensive literature review, 33 criteria related to health website evaluation were identified. Using this set of criteria, South Korean public librarians and users were asked to rate the importance of each criterion in surveys. A strong consensus was found between the two groups. The top 10 most highly rated criteria from both groups were identified and compared. The results led to the development of an initial set of 12 evaluation criteria for health websites. It is expected that the final set of criteria will be used by public librarians to recommend the best health websites to their users. Although the study was conducted in South Korean public libraries, the findings are applicable in providing evaluation services of health websites to libraries worldwide. 相似文献

As new venues of information and tools for information access are emerging, people's online information seeking behavior is dramatically evolving. While a majority of well-established and classical models of information seeking and behavior are still valid, there is a growing need to study and explain novel information sources and information seeking behaviors that are unique to these sources. One emerging domain is social question and answer (Q&A). This article develops a research agenda for social Q&A, reviewing recent studies and identifying core issues, questions, and challenges. 相似文献

This research examined the ways in which academic librarians and users interact when using social media tools such as Twitter and Weibo as well as end-users' and librarians' perceptions of the types of interaction through social media. The study conducted an analysis of 1600 microblog posts sampled from twenty university library Weibo (Chinese Twitter) sites and twenty library Twitter sites in English-speaking countries. The results were compared using Chi-Square analysis. Results indicated that at present academic librarians in English-speaking countries use post information relevant to the library (news and events) and respond to information/research inquiries. And academic librarians in China are likely to use Weibo to communicate with users and to disseminate library news. Given the lack of previous research on how social media such as micro-blogging in general facilitates communication between librarians and library users in academic libraries between in English-speaking countries and China, this study provides valuable information concerning librarians' and end-users' interactions of information/knowledge sharing activities, which will enable libraries to be better positioned to promote user engagement through SNS usage. 相似文献

The professional identity of librarians is established with regard to the current understanding of their knowledge practices. The global phenomenon of false and untrustworthy information circulating on social media platforms paints a new issue that librarians must conquer. Messages, content, news, and information on the web make it challenging for librarians to educate users as to where the sources come from and the need to evaluate for credibility and trustworthiness. During the pandemic, and with a surge of information disorders on social media, the World Health Organization recommended building resilience to misinform-ation and engaging and empowering communities to take positive action. This research seeks to explore the relationship between professional identities and the participation of librarians in an infodiverse environment, specifically by exploring how Filipino librarians applied aspects of their knowledge practices to the evaluation of social media health information during the pandemic. 相似文献

The information age demands that health sciences librarians take active roles in the educational process. Librarians have traditionally taught users how to access information. Now, with the proliferation of information, librarians must accept new roles and teach the user efficient techniques for evaluating and processing information as well. Innovative roles for librarians at Texas Tech University Health Sciences Center include teaching users to use technology for information management, to appraise literature critically for quality, and to develop skills for lifelong learning. This paper reviews the history of educational activities in health sciences libraries and describes the teaching programs at Texas Tech. 相似文献

The current study investigates how social media affordances influence individuals’ source credibility perceptions in the presence of risk information, specifically examining how bandwagon heuristics interact with different identity heuristics at the individual level. The MAIN model and warranting theory serve as the theoretical framework to examine the effects of bandwagon cues and identity cues embedded in retweets and users’ profile pages for health and risk online information processing. A posttest-only experiment with a self-report questionnaire was administered to participants. Results indicate that different online heuristic cues impact the judgments of competence, goodwill, and trustworthiness. Authority cues strongly influenced source credibility perceptions. A reverse-bandwagon effect was observed in influencing source credibility judgments. 相似文献

This paper empirically investigates the association of quality information provided by a government agency on social media and citizen’s online political participation. It further answers the why and how questions regarding the existence of this relationship by examining the mediating influence of transparency, trust, and responsiveness. The data was collected from 388 followers of the social media platforms of a government agency i.e. Punjab Food Authority and the findings of the analysis were obtained using structural equation modeling technique. The results reveal that the agency’s provision of quality information on social media was significantly related to perceived transparency, trust in agency, perceived responsiveness, and citizens’ online political participation. Moreover, the results show that perceived transparency mediates the relationship between agency’s provision of quality information on social media and citizens’ trust in agency. Additionally, trust in agency was an insignificant predictor and perceived responsiveness was a negative predictor of citizens online political participation, Also, trust in agency and perceived responsiveness suppressed the relationship between agency’s provision of quality information on social media and citizens’ online political participation. This study aims to bring awareness and contribution to the body of knowledge about the governmental use of social media and its resulting benefits since in developing countries like Pakistan the research in this area is sparse. Further, it provides strategic and practical suggestions to agencies regarding advantages of utilizing social media in their communication with citizens. 相似文献
