This is a tutorial on a set of core concepts related to Internet communication for my courses at Purdue University. For technical details, take a look at the PowerPoint presentation The Internet is not one net. It is more versatile than that. The…
Rhia improves upon work done by http://arxiv.org/abs/cond-mat/0408187 Community analysis algorithm proposed by Clauset, Newman, and Moore (CNM algorithm) finds community structure in social networks. Unfortunately, CNM algorithm does not scale well and its use is practically limited to networks whose sizes are…
MEJ Newman seems to have not only cracked the tough nut of detecting community structure in large networks but has also written the code to help the research community do it as well… Many kudos…. A. Clauset, M.E.J. Newman and C. Moore,…
Just as the man says, how do you detect communities in networks that are asymetric… We consider the problem of finding communities or modules in directed networks. The most common approach to this problem in the previous literature has been simply to…
Fascinating paper on revealing community structure in networks… Similar to Newman’s work… To comprehend the multipartite organization of large-scale biological and social systems, we introduce a new information theoretic approach that reveals community structure in weighted and directed networks. The method decomposes…
Is this a way of getting at what has become the holly grail of community research, namely detecting structure in any given group? We consider the problem of detecting communities or modules in networks, groups of vertices with a higher-than-average density of…
