Trust is a major aspect of decision making when two parties are involved, and the lack of face to face exchanges of the Internet deeply changes relations and behaviours regarding the available services. The already existing trust management systems over the Internet are one way only. Either they allow a provider to tell what it expects from a client (identification, qualifications), either it a...

Recommender systems using traditional collaborative filtering suffer from some significant weaknesses, such as data sparseness and scalability. In this study, we propose a method that can improve the recommender systems by combining similarity, trust and reputation. We modify the way that neighbors are selected by introducing the trust and reputation metrics in order to develop new relations be...

This article draws on empirical material concerning the communication and use of knowledge in experimental physics and its relations to the culture of theoretical physics. The role that trust plays in these interactions is used to create a model of social distance between interacting theoretical and experimental cultures. This article thus seeks to reintroduce trust as a fundamental element in ...

The article develops a process and control model for the analysis and design of inter-firm relations, in which both opportunism and trust play a role. Its aim is to develop a tool which helps to analyze combinations, balances and imbalances of trust and opportunism, formal and informal forms of governance, and viable sequences of strategies of governance, depending on different conditions. It e...

Evolutionary game-theory is a powerful tool to investigate the development of complex relations between individuals such as the emergence of cooperation and trust. But the propagation of genes is an unrealistic assumption when it comes to model fast-changing social interactions. We show how a transition from evolutionary game-theory to learning can be made. Specifically, we show how cooperation...

This paper discusses elements of inter-entrepreneurial trust in regional networks and clusters in terms of influencing business processes and economic viability in today’s economy. The message that can be extracted from the literature is that competitive advantage strongly depends on interfirm collaboration and that networks with a high degree of trust lead to entrepreneurship and innovation. T...

Research on trust in e-commerce typically views trust as an important condition of successful commercial exchange. It aims to identify relevant factors of trust and establish how these influence potential buyers' decisions to interact with vendors. The aim is to provide ways of increasing trust. This paper questions the validity of this traditional approach to trust in e-commerce. It criticizes...

Trust is a construct studied by a growing number of disciplines that, in time, following a natural process of convergence, have increasingly featured the multidisciplinarity of studies. To fully appreciate the increasing multidisciplinarity of trust literature, a review of the major research areas from the different disciplines has been done. This in order to understand two elements: (1) the ma...

Knots of trust are groups of community members having overall “strong” trust relations between them. In previous work we introduced the knot aware trust based reputation model. According to this model, in order to provide a member with reputation information relative to her viewpoint, the system must identify the knot to which that member belongs and interpret its reputation data correctly. In ...

Can we trust without any reliable truth information? Most trust architectures work in a similar way: a trustor makes some observations, rates the trustee, and makes recommendations to his friends. When he faces a new case, he checks his trust table and uses recommendations given by trustworthy friends to decide whether he will undertake a given action. But what if the observations that are used...
