Trust propagation is the principle by which new trust relationships can be derived from pre-existing trust relationship. Trust transitivity is the most explicit form of trust propagation, meaning for example that if Alice trusts Bob, and Bob trusts Claire, then by transitivity, Alice will also trust Claire. This assumes that Bob recommends Claire to Alice.(More)
In the absence of legal enforcement procedures for the participants of an open e-marketplace, trust and reputation systems are central for resisting against threats from malicious agents. Such systems provide mechanisms for identifying the participants who disseminate unfair ratings. However, it is possible that some of the honest participants are also(More)
There has been a lot of research and development in the field of computational trust in the past decade. Much of it has acknowledged or claimed that trust is a good thing. We think it's time to look at the other side of the coin and ask the questions why is it good, what alternatives are there, where do they fit, and is our assumption always correct? We(More)
ACORN (Agent-based Community Oriented Routing Network) is a distributed multi-agent architecture for the search, distribution and management of information in networks. ACORN utilizes the concept of 'information as agent' together with an application of Stanley Milgram's Small World Problem (the idea of Six Degrees of Separation) in order to route(More)
A layered architecture for advanced collaborative environments has been developed to map the definition of a collaboration task from the requirements needed to accomplish the task, to the collaboration services that can be used to satisfy those needs, and to the technologies on which the services can be delivered. The architecture takes into account the(More)
Trust transitivity is a common phenomenon embedded in human reasoning about trust. Given a specific context or purpose, trust transitivity is often manifested through the humans' intuition to rely on the recommendations of a trustworthy advisor about another entity that the advisor recommends. Although this simple principle has been formalised in various(More)
Two similar multiagent systems have been designed to address the issue of information sharing within a multiagent system. This paper examines architectural components that have been added to our information sharing societies, ACORN and MP3. Through this exploration, we conclude that these components and their underlying concepts can be added to other(More)
ACORN (Agent-based Community Oriented Routing Network) is a distributed multi-agent architecture for the search, distribution and management of information across networks. ACORN utilises the concept of 'information as agent' together with an application of Stanley Milgram's Small World Problem (the idea of the Six Degrees of Separation) in order to route(More)
