Online communities provide a social sphere for people to share information and knowledge. While information sharing is becoming a ubiquitous online phenomenon, how to ensure information quality or induce quality content, however, remains a challenge due to the anonymity of commentators. This paper introduces moderation into reputation systems. We show that moderation directly impacts strategic ...

As electronic commerce developed, it became clear that buyers and sellers needed a way to evaluate the reputation of potential trade partners. Online reputation systems were developed to meet this need. More recently, online reputation systems have expanded into additional domains such as the evaluation of college professors. The study proposed here examines the characteristics of two represent...

Current deployed reputation systems simply aggregate numerical ratings provided by buyers, but overlook the buyers’ subjectivity difference in evaluating the transactions with a seller. To address this problem, we propose a subjectivity alignment approach for reputation computation (SARC).

We examine the determinants of professional reputation. Does quantity of exposures raise reputation independent of quality? Does quality of the most important exposure have extra effects on reputation? In a very large sample of academic economists, there is little evidence that a scholar’s most influential work provides any extra enhancement of reputation. Quality rankings matter more than abso...

Reputation mechanisms provide a solution to this problem by discouraging fraudulent behavior and encouraging honest behavior of participants in the uncertain and un-trusted environment of e-market. This paper discusses trust and reputation relationships, and high...

Trust is required in file sharing peer-to-peer (P2P) systems to achieve better cooperation among peers and reduce malicious uploads. In reputation-based P2P systems, reputation is used to build trust among peers based on their past transactions and feedbacks from other peers. In these systems, reputable peers will usually be selected to upload requested files, decreasing significantly malicious...

Reputation systems can be used to foster good behaviour and to encourage adherence to contracts in e-commerce. Several reputation systems have been deployed in practical applications or proposed in the literature. This paper describes a new system called the beta reputation system which is based on using beta probability density functions to combine feedback and derive reputation ratings. The a...

a r t i c l e i n f o Corporate reputation is critical for cultivating stakeholder relationships and, specifically, for regaining public trust. Corporate reputation results from the firm's interactions with stakeholders, emphasizing the important role employees play in reputation management. However, employees are not necessarily aware of, or prepared for, this extra-role assignment, indicating...

Being able to manage reputation is an important social skill, but it is unclear whether autistic children can manage reputation. This study investigated whether 33 autistic children matched to 33 typical children could implicitly or explicitly manage reputation. Further, we examined whether cognitive processes-theory of mind, social motivation, inhibitory control and reciprocity-contribute to r...

Reputation management for peers in Bittorrent P2P network is very much important due to its open and anonymous nature. Some malicious peers distribute low quality or fake files in the network and pollute the environment. In this paper, we propose a fuzzy inference system to design P2P reputation management system which generates the reputation values for each torrent files by interacting with o...
