Giant component of University of Warsaw (UW) co-authorship network based on publications from years 2007-2009 (period 1) and 2010-2012 (period 2).
An igraph
object with undirected graph with 1486 vertices and 7505 edges, and the following attributes:
affiliation
– Vertex attribute identifying groups of departments:
natural sciences, social sciences, humanities, other (other departments of
UW), and external (co-authors who are not employees of UW)
color
, size
, label
– Vertex attributes for easy plotting. Color corresponds
to the affiliation
attribute.
p1
– Logical edge attribute. It is TRUE
if researchers incident on
that edge co-authored at least one publication in period 1.
p2
– Logical edge attribute. It is TRUE
if researchers incident on
that edge co-authored at least one publication in period 2.
The basis of this network is a co-authorship graph built from all articles, books, and chapters in edited volumes published in years 2007-2012 that have at least one employee of University of Warsaw as a (co)author.
