Graph similarity measures

We found out in Part I that the bipartite_projection method in igraph only sums the number of pairwise coincidences. That means, though, that even one shared element between sets is enough to link them. It doesn’t, at all, factor in how many elements of the sets are different or the totalnumber of elements … See more Before we get into the weeds of metrics, methods, and combinatorics (i.e., the mathematics of sets) let’s stop to think for a moment about just what we mean when we say that two things are similar. In general, we refer to … See more The Jaccard index is probably the most well-known and used of the set similarity measures.
