Though there are a variety of interesting papers on community structure (many of which I still have yet to read), I thought I’d place the Clauset-Newman-Moore paper as downloaded and in my shoebox because it seems that paper was one of the important ones in taking the developed idea and making it practical for very large networks. I like how it starts from the modularity optimization and takes it all the way to the data-structure specific solution into one packaged solution, whose code is readily available on the web–now that’s good research. I may consider that also for Shalizi and company’s CSSR, which has always intrigued me but I’ve never really sat down to really understand what’s going on.
I have recently added a “shoebox” to my home page. The basic idea is any papers, images, code, etc. that I feel at some level is worth storing locally, I place there in reverse chronological order.
What makes something worthy of the shoebox? Beats me, but you may get an idea by looking in it.
