In this paper we outline an approach for reasoning about the trustworthiness of users when advice from peers is provided and a majority opinion is central to the overall calculation. Typically, trust modeling frameworks have reasoned with binary reports from peers (i.e. trustworthy or not). In this paper, we illustrate how to do trust modeling when numeric advice is provided, instead (i.e. degr...

Trust is a construct of paramount importance in society. Accordingly, computational trust is evolving fast in order to allow trust in artificial societies. Despite the advances in this research field, most computational trust approaches evaluate trust by estimating the trustworthiness of the agents under evaluation (the trustees), without however distinguishing between the different dimensions ...

1. The Significance of Group Trustworthiness We value trustworthiness where we find it, in friends, colleagues, and strangers. This is because it is easier to cooperate with trustworthy individuals than with untrustworthy ones, but also because trustworthiness is appreciated for its own sake. Conversely, we resent untrustworthiness when we encounter it, and try to minimise interaction with untr...

We analyze the determinants of trust and trustworthiness in a matching equilibrium when agents have heterogeneous predispositions towards trusting and trustworthy behavior, there is transmission of information via both individual and collective reputations, and successful matches may persist. In new matches, more social trustworthiness breeds more individual trust. However, whether more social ...

Trust Establishment is one of the significant resources to enhance the scalability and reliability of resources in the cloud environment. To establish a novel trust model on SaaS (Software as a Service) cloud resources and to optimize the resource utilization of multiple user requests, an integrated software trust estimator with multi-user resource competence (IST-MRC) optimization mechanism is...

We propose generic declarative definitions of individual and collective trust relations between interacting agents and agent collections, and trust domains of trust-related agents in distributed systems. Our definitions yield (1) (in)compatibility, implicational, and transitivity results for trust relationships, including a Datalog-implementability result for their logical structure; (2) comput...

The present study aimed at investigating the relationship between organizational trust and organizational commitment in staff. Eighty-four persons from 101 staff of department of Sports and Youth in the province of Mazandaran responded to two questionnaires of “Organizational Trust Inventory (OTI)” developed by Shockley-Zalaba, Ellis, and Winograd (2000) and “Organizational Commitment Questio...

Online Social Networks (OSNs) have become an integral part of daily life in recent years. They have been used as a means for a rich variety of activities, such as seeking service providers or recommendations. In these activities, trust is one of the most important factors for participants’ decision-making process. Therefore, it is necessary and significant to predict the trust between two parti...

In this paper, we discuss a general methodology for analysis and modeling of trust relationships in distributed computing. We discuss the classification of trust relationships, categorize trust relationships into two layers and provide a hierarchy of trust relationships based on a formal definition of trust relationship. We provide guidelines for the analysis and modeling of trust relationships...
