According to my dictionaries, "credibility" is the property of being credible, with the latter meaning roughly the same as believable. So with this definition, a policy lacks credibility if it is one that could not reasonably be believed. It would appear that William Fellner (1976, 1979), who introduced the idea into the macroeconomic arena, chose this particular word because he believed that t...

Credibility influences a user’s interest in a web site. Once users perceive the credibility of a web site they will be more likely to use it. A combination of factors affects such credibility – such as the provider, content, aesthetics, accessibility and solution of technical problems. The aesthetics of a web site can affect a user’s first impressions of credibility. Experiments have shown that...

With the fast development of Social Networking Services (SNS) such as Twitter, which enable users to exchange short messages online, people can get information not only from the traditional news media but also from the masses of SNS users. However, SNS users sometimes propagate spurious or misleading information, so an effective way to automatically assess the credibility of information is requ...

The purpose of this study was to develop a psychometric questionnaire in order to evaluate the educational web site “Youth 2004” considering the attitudes and the perceptions of Greek Australian students. In addition, the differences among the age and sex were also investigated. Participants were 317 Greek Australian students, between the ages from 12-17 years old. Data was collected using an o...

I argue that taking the Practical Conditionals Thesis (PCT) seriously demands a new understanding of the semantics of such conditionals. Practical Conditionals Thesis: A practical conditional [if A][ought(B)] expresses B’s conditional preferability given A Paul Weirich has argued that the conditional utility of a state of affairs B on A is to be identified as the degree to which it is desired u...

In peer-to-peer (P2P) environments, a peer needs to interact with unknown peers for the services provided. This requires the trust evaluation prior to and posterior to interactions. This paper presents Trust: a novel and dynamic peer trust evaluation model, which aims to measure the credibility of peers’ recommendations, and thus to filter noise in responses and obtain more accurate and objecti...

Previous studies have demonstrated that varying these cues can affect how user's rate online health information [4], [5]. To date however there has only been one study that investigated whether the presence/absence of these cues affected the persuasiveness of a health website [6]. The outcome measure of this study (N=85) was self reported alcohol consumption; the cues investigated included adve...

In this paper focus is set on data reliability. We propose a few methods, which calculate credibility coefficients for objects stored in decision tables. Credibility coefficient of object is a measure of its similarity with respect to the rest of the objects in the considered decision table. It can be very useful in detecting either corrupted data or abnormal and distinctive situations. It is a...

Suitability of a diagnosis support and its intuitive transparency depend on medical knowledge representation. An appropriate representation should solve the following problems: a consistent interpretation of symptoms of different nature, formulation of rules that is close to diagnostic heuristics and implementation of a credibility measure that estimates diagnostic hypotheses. The paper suggest...

The change of economic circumstances in recent years has increased the gaps of credibility among firms, and the necessity to measure the credibility adequately is an important ever-increasing factor. As the result, it is essential for banks to assess the rating evaluation of borrowers appropriately in order to measure the amount of credit risk. This paper reviews preceding studies regarding mod...
