Handling uncertainty and vagueness in real world becomes a necessity for developing intelligent and efficient systems. Based on the credibility theory, a fuzzy clustering approach that improves the classification accuracy is targeted by this work. This paper introduces a design of an efficient set of fuzzy rules that are inferred by a hybrid model of SOFM (Self Organized Features Maps) and FRAN...

A Theory of Employment Guarantees: Contestability, Credibility and Distributional Concerns* This paper develops a theory of employment guarantees when labour markets are imperfect and when the credibility of government policy announcements could be in doubt. The basic feature of an EGS is that any individual who satisfies a set of specified criteria is guaranteed public employment at a given wa...

Recently the National Council on Compensation Insurance has significantly revised the Experience Rating Plan for Workers' Compensation. The new plan is referred to as the Revised Experience Ratlng Plan. It is a practical application of credibility theory using parameter uncertainty and risk heterogeneity. This paper compares the revised plan to the prior experience rating plan, with particular ...

Building upon the persuasion theory in the social psychology literature, this study investigates how companies can use microblogging services to influence consumers’ participation and brand loyalty. We develop and empirically test our research model using an online survey in China. Our findings show that persuasion factors, including information quality, perceived similarity, and source credibi...

The modeling of complex risk situations imposes the existence of multiple ways to represent the risk and compare the risk situations between them. In probabilistic models, risk is described by random variables and risk situations are compared by stochastic dominance. In possibilistic or credibilistic models, risk is represented by fuzzy variables. This paper concerns three indicators of dominan...

Information Retrieval methods, and search systems in general, are now a significant part of our interaction with the world outside of our direct reach. As such, they influence the way we perceive the reality we cannot directly experience. From here, the issue of credibility of IA systems is raised, and in this poster we look at the work which has already been done, observe its limits and propos...

Coalitional game deals with situations that involve cooperations among players, and there are different solution concepts such as the core,the Shapley value and the kernel. In many situations, there is no way to predict the payoff functions except for the expert experiencesand subjective intuitions, which leads to the coalitional game with fuzzy payoffs. Within the framework of credibility theo...
