We define a mathematical measure for the quantitative comparison of probabilistic computational trust systems, and use it to compare a well-known class of algorithms based on the so-called beta model. The main novelty is that our approach is formal, rather than based on experimental simulation.

In grid computing, trust has massive significance. There is lot of research to propose various models in providing trusted resource sharing mechanisms. The trust is a belief or perception that various researchers have tried to correlate with some computational model. Trust on any entity can be direct or indirect. Direct trust is the impact of either first impression over the entity or acquired ...

Trust and reputation are important factors that influence the success of both traditional transactions in physical social networks and modern e-commerce in virtual Internet environments. It is difficult to define the concept of trust and quantify it because trust has both subjective and objective characteristics at the same time. A well-reported issue with reputation management system in busine...

Multi-agent paradigms have been developed for the negotiation and brokering in B2C e-commerce .Few of the models consider the mental states and social settings (trust and reputation) but rarely any model depicts their combination. In this work, we present three mathematical models. First cognitive computational model which is combined model of belief, desire, intention (BDI) model for agent’s m...

How well can experienced Internet shoppers detect new forms of seller deception on the Internet? This study examines consumer evaluations of a real commercial web site and a fraudulent site that imitates it. The forged site contains malicious manipulations designed to increase trust in the site, decrease perceived risk, and ultimately increase the likelihood that visitors would buy from it. Bes...

In this work, a trust-based mixed-initiative scheme for teleoperation of multiple mobile robots is developed. In the proposed scheme, the task of controlling the robots is shared between a human operator and autonomous controllers of the mobile robots. The control inputs from human and the autonomous robot controllers are dynamically blended via a computational human-to-robot trust model. Meanw...

In a multiagent system, a truster keeps estimating and revising its trust for a trustee based on its interactions with trustee. Understanding these interactions and estimating trust from them is an interesting and challenging topic and therefore, several works have been pursued in this direction. Scissors et al. (Scissors et al. 2009) explore the linguistic similarity in chat messages to estima...
