A few months ago I stumbled across a simple measure of cluster overlap. Assume two clusters, A and B, that contain a total of n nodes of which m nodes belong to both clusters or, in other words, n is the number of nodes in the union of A and B and m the number of nodes in the intersection of A and B. The measure is something along the lines of  overlap=m/n=nodes in intersection/nodes in union. My problem is (1) that I have forgotten where I found this measure and (2) am not 100% sure that it was as simple as I recall. If you recognize this problem, can point me to a source or provide me with a correct or better formula, your help will be much appreciated.<div>
