ABSTRACT
In the following, three systems designed according to certain of the principles proposed in the preceding chapters are presented. The first system, GridVine, is a DHT-based Semantic Overlay Network fostering semantic interoperability through Semantic Gossiping. The second system, called PicShark and described in Chapter 9, builds on GridVine to offer picture sharing functionalities in environments where picture annotations are scarce and heterogeneous. Finally, Chapter 10 is dedicated to idMesh, a system that takes advantage of Emergent Semantics principles to disambiguate online identities.
