In peer-to-peer (P2P) environments, a peer needs to interact with unknown peers for the services provided. This requires the trust evaluation prior to and posterior to interactions. This paper presents Trust: a novel and dynamic peer trust evaluation model, which aims to measure the credibility of peers’ recommendations, and thus to filter noise in responses and obtain more accurate and objecti...

Trust can be a valuable ally when filtering information provided by the users of online forums or other tools of social interaction in the web, but it is also an implicit procedure performed by humans. This work studies the notion of Trust in online discussions and defines a generic model to describe, measure and evaluate it. An electronic survey was performed in order to understand how humans ...

High availability and diversity make Volunteered Geographic Information (VGI) an interesting source of information for an increasing number of use cases. Varying quality, however, is a concern often raised when it comes to using VGI in professional applications. Recent research directs towards the estimation of VGI quality through the notion of trust as a proxy measure. In this chapter, we inve...

Personalized Web Search customizes the search according to the information need of the user on the Web. In Personalized Web search, search is personalized using the search results of those users profile which have the information need similar to that of present/current user. It is realized that similarity measure of the users profile is not the sufficient criterion for identifying the trusted u...

Several previous studies measure the extent to which individuals trust other individuals and argue that individual trust is an important element of interaction in organizations and markets. However, a related topic is the extent to which it is possible for individuals to trust groups as separate entities. This concept, referred to as collective trust, has been previously discussed but not caref...

We combine two experiments and a survey to measure trust and trustworthiness—two key components of social capital. Standard attitudinal survey questions about trust predict trustworthy behavior in our experimentsmuch better than they predict trusting behavior. Trusting behavior in the experiments is predicted by past trusting behavior outside of the experiments. When individuals are closer soci...

Building trust is very important because fraud has been on rise in online electronic markets. Trust allows participant in online electronic markets to overcome perceptions of risk and uncertainty and make a deal. This paper proposes a design of a mechanism of building trust in online electronic markets. The interesting aspects of this mechanism is that it not only improves reputation rating mea...

We concentrate on discussing a class of two-person zero-sum games with rough payoffs. Based on the expected value operator and the trust measure of rough variables, the expected equilibrium strategy and r-trust maximin equilibrium strategy are defined. Five cases whether the game exists r-trust maximin equilibrium strategy are discussed, and the technique of genetic algorithm is applied to find...
