The advent of the internet has resulted in the exponential growth in availability of information as well as the sources from which this information can be gathered. Information has become an asset as well as a vital tool for decision making processes. In order to gain new information, a business is often required to give some information, it is already in possession of, up. This information cou...

BACKGROUND The development and implementation of a remediation plan for the residual arsenic trioxide stored at the former Giant Mine site in the Canadian Northwest Territories has raised important issues related to trust. Social and individual trust of those responsible for making decisions on risks is critically important in community judgements on risk and the acceptability of risk managemen...

We believe that distrust can be as important as trust when agents are making a decision. An agent may not trust a source because of lack of positive evidence, but this does not necessarily mean the agent distrusts the source. Trust and distrust have to be considered as two separate concepts which can coexist. We are aware that an adequate way to take this fact into account is by considering exp...

The significance of efficient security mechanisms in P2P and Grid systems is unquestionable, since security is considered to be a quality of service factor for such systems. Traditional security mechanisms in P2P and Grid systems include encryption, sand-boxing and other access control and authentication mechanisms. Unfortunately these techniques incur additional overhead. By using trust and re...

Trust has been viewed as an integral component of agent decision making in the context of multiagent systems (MASs). Various formal and semi-formal trust schemes, motivated by diverse considerations and influenced by various fields of study, have been proposed, implemented, and evaluated. We believe that there still exists a pressing need for developing a comprehensive trust management scheme t...

While trust is seen as central to most social relations, most writers, including sociologists of science, assume that modern trust relations--especially those in regulatory relationships - tend towards the impersonal. Drawing on ethnographic material from one kind of scientific oversight body--research ethics committees based in the UK NHS--this paper argues that interpersonal trust is crucial ...

Trust and reputation have been proposed in the Multiagent Systems area as a way to assist agents to select good partners in order to improve interactions between them. As well as trust, agent emotions have been studied with the aim of making the actions and reactions of the agents more like those of humans. In this paper, we present a trust model based on emotions. It is a hybrid mathematical a...

In many computing systems, information is produced and processed by many people. Knowing how much a user trusts a source can be very useful for aggregating, filtering, and ordering of information. Furthermore, if trust is used to support decision making, it is important to have an accurate estimate of trust when it is not directly available, as well as a measure of confidence in that estimate. ...

Cyber-physical system (CPS) provides more powerful service through combining software service and physical device. It is an effective solution to organize various CPS services to realize collaborative decision making (CDM). In CPS, finding out the most competent participators for CDM sponsor is a core problem. To solve this problem, we propose a novel capacity and trust computation based CPS se...

This paper presents a personalized approach for distributed trust management by employing the k-means range algorithm, a combination of the partitional kmeans clustering algorithm with orthogonal range search concepts. The aim of this approach is to aid the human or computer agent in organizing information from multiple sources into clusters according to its “trust features”. Thus the agent can...
