WebThe graph representation of a similarity matrix. The numbered squares correspond to the objects, while the weights on certain edges correspond to the dissimilarities. 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 things as similar when they are neither the quite the same nor are they entirely different. … See more 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. … See more The Jaccard index is probably the most well-known and used of the set similarity measures. You may also see this one referenced as the … See more We now have three very specific ways to measure similarity, so how do we choose which measure to use? Well, there’s no “one size fits all” … See more

WebThe n-by-n matrix S = (S i, j) i, j = 1, …, n contains pairwise similarity values between connected nodes in the similarity graph. The similarity matrix of a graph is also called an adjacency matrix. The similarity matrix is symmetric because the edges of the similarity graph are directionless. A value of S i,j = 0 means that nodes i and j of ...
