Nima Dokoohaki

The document discusses security considerations for semantic web services. It describes how semantic web services add formal descriptions to allow automated discovery, composition and invocation of web services. The document outlines key security dimensions like authorization, privacy and trust that are important in this context. It proposes a semantic policy framework to address security requirements through semantically-described policies and addresses some challenges in standardizing approaches.
