In recent years, user-supplied reviews have increased to become widely prevalent on many websites. Some reviewers (users who comment on items) provide valuable information. Others provide information many people already know. Our goal is to identify credible reviewers who provide valuable information. Twomethods can be used to measure reviewer credibility: assessing reviewers based on the conte...

The relative poverty measure is the most prominent and most–quoted of the EU social inclusion indicators. This paper argues that, while pragmatically defensible in the pre–enlargement setting, the estimates and relative rankings the below–60%–of–median–income measure produces in the enlarged EU context is stretching its validity, credibility and hence legitimacy as a prime indicator to an unten...

The credibility of website has become a decisive factor for the website’s survival and an important driving force of promotion and market expansion. Currently, the credibility of we...

The National Aeronautics and Space Administration (NASA) has endeavored to develop a consistent method of assuring the credibility of simulation results. Requirements like "accurate enough for a particular use" present problems. How do you measure accuracy? What has to be accurate? What factors are measured? How do you quantify “enough for the particular use?” Which functions are measured? When...

In reputation systems, agents collectively estimate the others’ behaviours through feedbacks to decide with whom they can interact. To avoid manipulations, most reputation systems weight feedbacks with respect to the agents’ reputation. However, these systems are sensitive to some strategic manipulations, like oscillating attacks or whitewashing. In this paper, we propose (1) a credibility meas...

This study examines how bloggers establish and enhance the credibility of their blogs through a series of blogging practices. Based on an analysis of interviews with 22 independent bloggers who blog on a range of topics, we present audience-aware credibility as a theoretical construct. Audience-aware credibility is defined as how bloggers signal their credibility based on who they think their a...

Internet users contribute content online through platforms such as blogs, wikis, video sharing sites, and sites that allow user feedback.

Credibility coefficients reflect similarity of objects in respect to other ones in information systems. For decision tables we can use credibility coefficients based on decision rules. Knowledge discovery methods can extract rules from an information system. The knowledge represented by the rules may be not exact due to improper data. Calculation of credibility coefficients is based on an assum...

With the rapid increase of 3-dimensional (3D) content, considerable research related to the 3D human factor has been undertaken for quantitatively evaluating visual discomfort, including eye fatigue and dizziness, caused by viewing 3D content. Various modalities such as electroencephalograms (EEGs), biomedical signals, and eye responses have been investigated. However, the majority of the previ...
