Abstract
An important aspect governing the growth of complex networks is
homophily, which is defined as the tendency of sites to link with others
which are similar to themselves. Here, we modify the preferential
attachment from Barabasi-Albert model by including a homophilic term.
Comparisons are made with the Barabasi-Albert model, fitness model and
our present model considering its topological properties: degree
distribution, time dependence of the connectivity, shortest path length
and clustering coefficient. We verify the existence of a region where
the characteristics of sites play an important role in the rate of
gaining links as well as in the number of links between sites with
similar and dissimilar characteristics.
