THISESSAY REVIEWS THE ISSUES SURROUNDING determinations of the credibility of online materials. The author argues, first, that the World Wide Web, and the larger Internet, comprise some very difficult and distinctive features that make conventional ways of assessing credibility adequate only within a fairly bounded frame; second, that beyond this bounded frame, standard credibility measures enc...

Introduction The availability and diversity of educational materials have greatly evolved over the past decade. In particular, resources such as online content and simulation tools more pervasively have been used by students as learning materials. Although this opens up greater access to a variety of educational resources, it also introduces the need to critically evaluate the accuracy and unde...

While the problem of incomplete data in databases has been exten sively studied a relatively unexplored form of uncertainty in databases called inaccurate data demands due attention Inaccurate data results when data are contributed by various information agents with associated credibility Though the data itself is total or complete the reliability of the data now depends on the agents credibili...

Firms often use both objective/verifiable and subjective/non-verifiable performance measures to provide employees with effort incentives. We study a principal/multi-agent model in which a verifiable team-based performance measure and nonverifiable individual performance measures (one for each agent) are available for contracting. A problem with tying rewards to non-verifiable measures is that t...

We investigated the effects of aging and individual differences on credibility judgment of online health information. Analysis of credibility judgment ratings revealed that older adults were less influenced by argument strength in content messages and contextual Website features than younger adults. Verbal protocol analysis revealed that older adults tended to accept the facts they read on the ...

Model credibility index is defined to be a sample size under which the power of rejection equals 0.5. It applies goodness-of-fit testing thinking and uses a one-number summary statistic as an assessment tool in a false model world. The estimation of the model credibility index involves a bootstrap resampling technique. To assess the consistency of the estimator of model credibility index, we in...

To enhance the credibility level/measure of an intuitionistic fuzzy set (IFS), this study proposes notion (IFCS) to express hybrid information a pair membership degree and nonmembership degree. Next, we propose generalized distance similarity measures between IFCSs then further generalize weighted measure trigonometric function-based IFCSs, including cosine, sine, tangent, cotangent based on IF...

communication and information literacy fields about the skills that Internet users need to assess the credibility of online information. The article reviews current recommendations for credibility assessment, empirical research on how users determine the credibility of Inter-net information, and describes several cognitive models of online information evaluation. Based on the literature review ...

Web credibility is becoming a significant factor in increasing user satisfaction, trust, and loyalty. Web credibility is particularly important for people who cannot visit an institution for one reason or other and mostly depend on the website, such as online distance education students. Accordingly, universities and educational websites need to determine the types of credibility problems they ...

But like many aspects of our human society, computers seem to be facing a credibility crisis. Due in part to the popularization of the Internet, the cultural myth of the highly credible computer may soon be history. Although healthy skepticism about computers can be a good thing, if the pendulum swings too far in this direction, computers—especially with respect to Web-based content—could be vi...
