Recommender systems promise to support travelers in complex decision-making processes; however, whether a recommendation is seen as credible advice and actually taken into account not only depends on travelers' perceptions of the recommendation but also of the system as the advice giver. A scale to measure recommender system credibility was developed and tested. The results confirm that credibi...

Celebrity Endorsement has become one of the important tools in advertisement persuading customers. No study has been yet conducted in Pakistan to measure the impact of credibility of celebrity on the buying intentions of customers. This paper investigates the credibility of celebrity endorser influence on consumers buying intention and also whether the experience of celebrity with the usage of ...

There are various types of uncertainty in the real world. This is a motivation to investigate the behavior of uncertain phenomena. Random phenomena is one class of objective uncertain phenomena which has been well studied. Probability theory is an efficient tool to study the behavior of random phenomena. Besides randomness, fuzziness is a basic type of subjective uncertainty initiated by Zadeh....

BACKGROUND Current literature evidences higher accuracy of immunological (iFOBT) vis-à-vis guaiac-based (gFOBT) fecal occult blood tests for colorectal cancer (CRC) screening. Few well-designed head-to-head comparisons exist. AIM This meta-analysis assesses the performances of two iFOBTs compared with an established gFOBT using colonoscopy as the gold standard. METHODS We mobilized a bivari...

We introduce a cardinality constrained multi-objective optimization problem for generating efficient portfolios within a fuzzy mean-absolute deviation framework. We assume that the return on a given portfolio is modeled by means of LR-type fuzzy variables, whose credibility distributions collect the contemporary relationships among the returns on individual assets. To consider credibility measu...

A clutch of '-isms' characterises the approach to consciousness which David Chalmers defends: dualism, epiphenomenalism, functionalism, anti-reductionism, and -probably -panpsychism. (The author would no doubt want 'naturalism' included in the list as well, but as we shall see, Chalmers' predilection to describe his theory as 'scientific' stretches credibility.) While the book does not, as far ...

This paper treats risk based on the notions of credibility measure and credibility expected value. Firstly, the paper derives and discusses the credibility expected value. Secondly, the paper presents a new method of analysis of possibilistic portfolios. The new step is a construction by which with a possibilistic portfolio one associates a probabilistic portfolio. The problem solving of possib...

The size and diversity of today’s online content makes it hard for the users to evaluate its credibility. To address this problem, we aim to build a fully-decentralized and robust recommender system to support web credibility assessment. In this proposal, we highlight three pieces of work that serve as starting points for our research, which we organize in a number of steps: (1) an extensive an...
