The knowledge management literature suggests that reuse of externalized knowledge is fundamental for improved efficiency, reduced costs and reduced dependency on individual know-how. Rather than considering knowledge as a specific thing the paper relates knowledge to the work people do. It suggest that knowledge management literature avoids to take into account how knowledge needs to be made cr...

The literature on network management is extensive. However, it generally explores network structures, neglecting the impact of management strategies. In this article we assess the effect of management strategies on network outcomes, providing empirical evidence from 119 urban revitalization networks. We go beyond current work by testing a path model for the determinants of network outcomes and ...

Trust is an important tool in human life, as it enables people to cope with the uncertainty caused by the free will of others. Uncertainty and uncontrollability are also issues in computer-assisted collaboration and electronic commerce in particular. A computational model of trust and its implementation can alleviate this problem. This survey is directed to an audience wishing to familiarize th...

We propose a formal model for reputation-based trust management. In contrast to credential-based trust management, in our framework an agent’s reputation serves as the basis for trust. For example, an access control policy may consider the agent’s reputation when deciding whether to offer him a license for accessing a protected resource. The underlying semantic model is an event semantics inspi...

The open, sharing and anonymous nature of peer-to-peer (P2P) network has offered opportunities and threats for the development of distributed computing technology. One feasible way to minimize threats is to establish the reputation-based global trust model. Most of current trust mechanisms are not only unable to restrain effectively such malicious behavior as collusive attacks, but also take no...

Trust management is a concept of automatic verification of access rights against distributed security policies. A policy is described by a set of credentials that define membership of roles and delegation of authority over a resource between the members of roles. Making an access control decision is equivalent to resolving a credential chain between the requester and the role, which members are...
