Multidimensional Context Representations for Situational Trust

We propose a generic model for situation representation in agent trust models. As we argue that general trust models are inappropriate in complex environments and their use for advanced decision-making is limited due to the lack of detail, we introduce a generic framework for context representation in trust model. Presented method is independent of the trustfulness representation formalism in the underlying trust model. It doesn´t prescribe any particular form for the set of reference contexts that holds the trustworthiness information in the context space: we define and evaluate the baseline approach with regular grid and discuss future extension towards more adaptive approaches using octant trees and fuzzy clustering techniques
