Analyzing and Modeling Communities Interactions through Social Semantic Web Applications: interacting with dynamic semantic systems of the web.

The web is a worldwide system never sleeping. In all its dimensions the complexity of the web is growing. The dynamics of the system and its ever-changing contexts make it very difficult to interact with it. The flexibility and extensibility of semantics-based systems is more and more used to tackle the diversity of web resources and applications through metadata describing web resources. But the growing use of semantic representations also augments the complexity of the web and makes it more difficult to interact with.
