Social question-and-answer (Q&A) sites have the potential to serve as a useful source of online information based on their content-focused and collaborative nature. Although previous research has examined various attributes of high-quality information on social Q&A sites (e.g., best answers), relatively less attention has been paid to what affects users’ credibility assessments of information in the social Q&A context. The present study developed a social Q&A platform-specific framework for web credibility assessment, including 21 criteria under six types of web credibility, based on a literature analysis and case study of two online Q&A communities, Stack Exchange and Wikipedia Reference Desk. Using the selected sites’ policies and guidelines (n = 46) as the source of evidence, the case study revealed that content-related attributes (e.g., evidence-based, pertinence) were most frequently identified (12 of 21 criteria) as potential cues and heuristics for web credibility assessments of social Q&A sites, followed by author-related (five of 21; e.g., reputation) and design-related (four of 21; e.g., engaging design) factors. Design-related criteria were rarely included in previous models of web credibility on social Q&A or similar peer-knowledge production platforms. However, our findings showing that both Stack Exchange and Wikipedia Reference Desk have policies regarding all four design-related criteria in our framework—engaging design, moderation, design appropriateness, and ease of use—indicate the potential influences of design features on users’ web credibility assessment on social Q&A sites. Some differences emerged between the two cases, such as policies regarding the answerer's credentials or semantic accuracy that are present on Wikipedia Reference Desk but absent on Stack Exchange. Such differences in the sites’ policies reflect how they position themselves as social Q&A communities—Wikipedia, of which Wikipedia Reference Desk is a part, as an encyclopedia, and Stack Exchange as a community-based platform for learning, sharing knowledge, and building careers of users. 相似文献

Transaction uncertainty is an impediment to customer satisfaction and remains a problem in the dual-channel retailing context. Most consumers use web stores for information and evaluation. This process influences their subsequent retailer selection and consumer satisfaction. In this study, the retailer brand, as the source of transaction information, is considered as a solution to the problem of transaction uncertainty. Brand attractiveness, the affective aspect of brand, is identified as an affective-based uncertainty mitigator and is considered together with brand credibility, the cognitive aspect of brand. Drawing on the source attractiveness/credibility model, retailer brand attractiveness and credibility are proposed and confirmed to reduce transaction uncertainty, in turn improving customer satisfaction. The moderating role of online–offline channel integration on the uncertainty reduction effect of retailer brand attractiveness and credibility is investigated. Online–offline channel integration has been found to be the essential condition for the uncertainty reduction effect of retailer brand attractiveness. Online–offline channel integration is also found to form a synergy with retailer brand credibility in reducing uncertainty. These findings show that the web stores of dual-channel retailers should invest in brand attractiveness and credibility orderly and coordinate brand investment with online–offline channel integration. 相似文献

The spreading of misinformation and disinformation is a great problem on microblogs, leading user evaluation of information credibility a critical issue. This study incorporates two message format factors related to multimedia usage on microblogs (vividness and multimedia diagnosticity) with two well-discussed factors for information credibility (i.e., argument quality and source credibility) as a holistic framework to investigate user evaluation of microblog information credibility. Further, the study draws on two-factor theory and its variant three-factor lens to explain the nonlinear effects of the above factors on microblog information credibility. An online survey was conducted to test the proposed framework by collecting data from microblog users. The research findings reveal that for the effects on microblog information credibility: (1) argument quality (a hygiene factor) exerts a decreasing incremental effect; (2) source credibility (a bivalent factor) exerts only a linear effect; and (3) multimedia diagnosticity (a motivating factor) exerts an increasing incremental effect. This study adds to current knowledge about information credibility by proposing an insightful framework to understand the key predictors of microblog information credibility and further examining the nonlinear effects of these predictors. 相似文献

Web sites often provide the first impression of an organization. For many organizations, web sites are crucial to ensure sales or to procure services within. When a person opens a web site, the first impression is probably made in a few seconds, and the user will either stay or move on to the next site on the basis of many factors. One of the factors that may influence users to stay or go is the page aesthetics. Another reason may involve a user’s judgment about the site’s credibility. This study explores the possible link between page aesthetics and a user’s judgment of the site’s credibility. Our findings indicate that when the same content is presented using different levels of aesthetic treatment, the content with a higher aesthetic treatment was judged as having higher credibility. We call this the amelioration effect of visual design and aesthetics on content credibility. Our study suggests that this effect is operational within the first few seconds in which a user views a web page. Given the same content, a higher aesthetic treatment will increase perceived credibility. 相似文献

This study examined: (1) whether a peripheral cue and subject knowledge influenced the credibility judgments in the context of Wikipedia; and (2) whether certain factors affected heuristic processing in the context of Wikipedia. The theory of bounded rationality and the heuristic-systematic model serve as the basis of this study. Data were collected employing a quasi-experiment and a web survey at a large public university in the Midwestern United States in the fall of 2011. The study participants consisted of undergraduate students from nine courses whose instructors agreed to their participation. A total of 142 students participated in the study, of which a total of 138 surveys were useable. The major findings of this study include the following: a peripheral cue and knowledge influenced the credibility judgments of college students concerning Wikipedia. The effect of a peripheral cue on credibility judgments was not different between those with high versus low knowledge. Finally, perceived credibility was positively related to heuristic processing, but knowledge, cognitive workload or involvement in a topic was not. This study suggests that educators and librarians need to integrate heuristic approaches into their literacy programs, guiding students to effectively use and not blindly accept cues. Wikipedia needs to offer noticeable cues that can help Wikipedia readers assess the credibility of information. The role of perceptions in heuristic processing needs further investigation. Further, this study demonstrates the strength of a peripheral cue on credibility judgments, suggesting that further research is needed when cues lead to effective credibility judgments and when cues lead to biased credibility judgments. Finally, this study provides the suggestion of an integrated model of the theory of bounded rationality and the heuristic-systematic model that can enhance our understanding of heuristics in relation to credibility judgments. 相似文献

Although commonly confused, the values inherent in copyright policy are different from those inherent in scholarly standards for proper accreditation of ideas. Piracy is the infringement of a copyright, and plagiarism is the failure to give credit. The increasing use of Web-based electron publication has created new contexts for both piracy and plagiarism. In so far as piracy and plagiarism are confused, we cannot appreciate how the Web has changed the importance of these very different types of wrongs. The present paper argues that Web-based publication lessens the importance of piracy, while it heightens the need for protections against plagiarism. Copyright policy protects the opportunity for publishers to make a profit from their investments. As the cost of publication decreases in the electronic media, we need fewer copyright protections. Plagiarism is the failure to abide by scholarly standards for citation of sources. These standards assure us that information can be verified and traced to its source. Since Web sources are often volatile and changing, it becomes increasingly difficult and important to have clear standards for verifying the source of all information. 相似文献

Journalists, emergency responders, and the general public use Twitter during disasters as an effective means to disseminate emergency information. However, there is a growing concern about the credibility of disaster tweets. This concern negatively influences Twitter users’ decisions about whether to retweet information, which can delay the dissemination of accurate—and sometimes essential—communications during a crisis. Although verifying information credibility is often a time-consuming task requiring considerable cognitive effort, researchers have yet to explore how people manage this task while using Twitter during disaster situations.To address this, we adopt the Heuristic-Systematic Model of information processing to understand how Twitter users make retweet decisions by categorizing tweet content as systematically processed information and a Twitter user’s profile as heuristically processed information. We then empirically examine tweet content and Twitter user profiles, as well as how they interact to verify the credibility of tweets collected during two disaster events: the 2011 Queensland floods, and the 2013 Colorado floods. Our empirical results suggest that using a Twitter profile as source-credibility information makes it easier for Twitter users to assess the credibility of disaster tweets. Our study also reveals that the Twitter user profile is a reliable source of credibility information and enhances our understanding of timely communication on Twitter during disasters. 相似文献

This study examines the impacts of social influence, which are manifested by popularity and source credibility, on social endorsement in social Q&A community; and how the relationship is impacted by temporal-spatial factors. By collecting panel data from a large platform, the results of an econometric model demonstrate that popularity and source credibility are positively associated with social endorsement. With respect to the moderation effects, the results further show that time distance strengthens the effect of popularity on the social endorsement, but undermines the effect of source credibility; while crowdedness plays the role that strengthens the impact of popularity on the social endorsement, it has no significant moderating effect on the relationship between source credibility and social endorsement. Both theoretical and practical implications are discussed. 相似文献

This research is a part of ongoing study to better understand citation analysis on the Web. It builds on Kleinberg's research (J. Kleinberg, R. Kumar, P. Raghavan, P. Rajagopalan, A. Tomkins, Invited survey at the International Conference on Combinatorics and Computing, 1999) that hyperlinks between web pages constitute a web graph structure and tries to classify different web graphs in the new coordinate space: out-degree, in-degree. The out-degree coordinate is defined as the number of outgoing web pages from a given web page. The in-degree coordinate is the number of web pages that point to a given web page. In this new coordinate space a metric is built to classify how close or far are different web graphs. Kleinberg's web algorithm (J. Kleinberg, Proceedings of the ACM-SIAM Symposium on Discrete Algorithms, 1998, pp. 668–677) on discovering “hub web pages” and “authorities web pages” is applied in this new coordinate space. Some very uncommon phenomenon has been discovered and new interesting results interpreted. This study does not look at enhancing web retrieval by adding context information. It only considers web hyperlinks as a source to analyze citations on the web. The author believes that understanding the underlying web page as a graph will help design better web algorithms, enhance retrieval and web performance, and recommends using graphs as a part of visual aid for search engine designers. 相似文献

Regulation of clinical practice is a characteristic aspect of the medical profession. Regardless of whether this regulation derives from government-sourced guidelines or materials from government-sponsored institutions, it results in a high production of information resources (institutional information resources), which are disseminated to the clinical stuff in order to ensure compliance. In that case, the issue of credibility of these information resources might arise, since medical practice is characterized by a high frequency of change. The latter involves a continuous effort on the part of the clinical staff, which is motivated by work-related factors (e.g., need for compliance) or personal motivation (e.g., need for self-improvement). In this study we consider a simple trust model, according to which we assume that perceived trust is a direct antecedent of perceived credibility. We evaluate whether work-related or personal motivating factors influence the relation between perceived credibility and trust toward institutional information sources and how the effect of each factor affects this relation. Findings suggest that work-related factors have a higher impact on the relation between credibility and trust than personal motivation factors, while they are stressing the important role of hospital libraries as a dissemination point for government-sponsored information resources. 相似文献

Drawing upon elaboration likelihood model (ELM) and espoused culture, this study predicts that eWOM reader's individualism–collectivism orientation (ICO) moderates eWOM antecedent factors’ effects on the perception of information credibility. 274 data were collected from two leading electronic word-of-mouth (eWOM) forums in China, the results confirm our prediction: eWOM reader's ICO positively moderates information sidedness’ effect on the perception of information credibility, it also negatively moderates the relationships between information consistency/information rating and information credibility. These findings validate the necessity and importance to consider readers’ espoused cultural differences in eWOM context. 相似文献
