In order to better model agent-agent interaction, a robust model for trust is necessary. Many computational trust models have been created in the past, but during the course of research, I’ve found none that model every facet of trust appropriately. In order to rectify this, I’ve devised a model based off of prior work in the field, and some ideas gleaned from sociology and neurobiology. The co...

Trust is a central concept in public-key cryptography infrastructure and in security in general. We study its initial quanti…cation and its spread patterns. There is empirical evidence that in trust-based reputation model for virtual communities, it pays to restrict the clusters of agents to small sets with high mutual trust. We propose and motivate a mathematical model, where this phenomenon e...

The increasing reliance on information gathered from the Web and other Internet technologies (P2P networks, e-mails, blogs, wikis, etc.) raises the issue of trust. Trust policies are needed to filter out untrustworthy information. This filtering task can be leveraged by the increasing availability of Semantic Web metadata that describes the information retrieved. It is necessary, however, to ad...

Trust models that rely on recommendation trusts are vulnerable to badmouthing and ballot-stuffing attacks. To cope with these attacks, existing trust models employ different trust aggregation techniques to process the recommendation trusts and combine them with the direct trust values to form a combined trust value. However, these trust models are biased as recommendation trusts that deviate to...

current research examines the impact of perceived justice (including distributive justice, procedural justice and interactional justice) on perceived service quality and customer behavioral intentions (including word of mouth, trust and revisit intention).statistical sample comprises 120 customers of iran insurance company in shiraz holding automobile insurance and have record of visiting the c...

The growth in knowledge sharing enabled by the (Semantic) Web has made trust an increasingly critical issue. Based on explicit inter-agent trust relations, a trust network emerges on the (Semantic) Web in the knowledge sharing context. The concept of a trust network and its application to knowledge sharing have received recent attention but neither their structural properties (e.g. dynamics, co...
