Complex Networks. Complex Networks Complex Networks are everywhere.
Many phenomena in nature can be modeled as a network, as brain structures, protein-protein interaction networks, social interactions and the Internet and WWW. All such systems can be represented in terms of nodes and edges indicating connections between nodes. In Internet, for example, the nodes represent routers and the edges the physical connections between them. Network of Networks: the last frontier of Complexity Science. Networks of Networks: The Last Frontier of Complexity. Contributions from leaders in the field of Network Science Encapsulates developments in this emerging field in a clear manner Interdisciplinary fields are represented The present work is meant as a reference to provide an organic and comprehensive view of the most relevant results in the exciting new field of Networks of Networks (NetoNets).
Seminal papers have recently been published posing the basis to study what happens when different networks interact, thus providing evidence for the emergence of new, unexpected behaviors and vulnerabilities. X 4, 021014 (2014) - Driving Interconnected Networks to Supercriticality. In the age of Facebook, Twitter, and email, the phenomena of a story, an idea, or a certain behavior going “viral” are commonplace.
But, viewed scientifically, such phenomena are far from being trivial. First of all, the underlying mechanisms have certain degrees of unpredictability, or randomness. Moreover, the structure of human connectivity that enables such viral spreading (or “diffusion”) is actually composed of many layers of networks arbitrarily interconnected. Center for Complex Networks and Systems Research. From networks to hypernetworks in complex systems science. Jeffrey Johnson (Open University, UK) Abstract: Complex systems have multilevel dynamics emerging from interactions between their parts.
Networks have provided deep insights into those dynamics, but only represent relations between two things while the generality is relations between many things. Hypergraphs and their related Galois connections have long been used to model such relations, but their set theoretic nature has inadequate and inappropriate structure.

Link analysis algorithms leverage hyperlinks created by authors as semantic endorsements between pages, while social bookmarks provide a way to leverage annotations by information consumers as a source of information about pages. This project explores a novel approach that is a synergy of the two: soliciting annotations from users about the content of pages, in a way that implicitly forms networks of relationships between and among resources and tags.
