The objective of this paper is to present a study of the publication profile of Computer Science graduate programs, using collaboration social networks. In order to attain this goal, we considered 8 programs in Brazil, 16 programs in North America (13 in the United States and 3 in Canada) and 6 in Europe (3 in the United Kingdom, 2 in France and 1 in Switzerland). For these 30 programs, we obtained a set of 2,007 faculty members and collected their publication data from DBLP, summing up 176,537 authors and 352,766 publication citations distributed among 2,176 publication vehicles. The results obtained from different measurements over the social network show differen- ces in the publication profile of Brazilian, North-American and European pro- grams. For instance, the size of the giant component indicates reduced colla- boration between European faculty members when compared to their Brazilian and North American counterparts. A comparisson between the social networks of 30 different Computer Science sub-areas shows differences in the diversity of network relationships (clustering coefficient) for sub-areas closely related to Mathematics, such as Algorithms and Theory. We also present the results of a inter relationship study involving Computer Science sub-areas.
