A scale based trust model for multi-context environments

When interactions among users of a system have to take place, for example, over the internet, establishing trust relationships among these users becomes crucial. However, the way this trust is established depends to a certain extent on the context where the interactions take place. Most of the times trust is encoded as a numerical value that might not be very meaningful for a non very experienced user. In this paper we propose a model that takes into account the semantic and the computational sides of trust. This avoids users having to deal directly with the computational side, having instead to deal with meaningful labels such as Bad or Good in a given context. Keyword 1 Trust, trust scale, labels of trust, multi-context trust.
