" Who is keeping you in that community? "

Abstract

It is a common experience that groups of people with tight 
inter-relations can be easily formed or dissolved. These groups are not 
however restricted to social environments; they can be found in systems 
ranging from protein interaction networks to the Web and can be seen as 
manifestations of complexity. Within the framework of graph theory such 
groups are known as clusters or communities and many techniques have 
been proposed to detect them.

In this talk I will show that a recently introduced inference method on 
networks is able not only to determine clusters but also to measure the 
extent to which each element influences the group membership of its 
neighbors. We demonstrate the generality and relevance of this 
information-based hierarchy with several real-world examples. This is 
joint work with Jose Javier Ramasco of ISI Torino.
