" Who is keeping you in that community? "
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.
