Real-world Trust Policies

One of the most important problems on the semantic web area is the one of trust. The growing exchange of semantic web data raises the need of policies that allow filtering out untrustworthy information. It is necessary, however, to model adequately the concept of trustworthiness, otherwise one may end up with operational trust measures that lack a clear meaning. It is also important to have a path from one’s trust requirements to concrete trust policies. Our proposal is to ease the building of this path, through a representation of trust requirements grounded on a specific notion of trust and an algorithm to map this representation to trust policies. We report our ongoing effort on this direction.
