ASSESSING TRUST IN THE SEMANTIC WEB

摘要

The concept of Semantic Web - a new WWW architecture that enhances content with formal semantics and machine-understandable metadata - is briefly presented. Then trusted behaviour of agents in this, fundamentally dynamic, environment is discussed. The paper proposes a probabilistic approach for trust assessing and representation. The methods of comparing probability-based trust levels are also presented. Our approach postulates a simple representation of trust primitives (sets of ratings) which are then used by more sophisticated methods. The proposed solution is also flexible and allows each of the network agents to conduct his own trust policy.
