Figure 4From: Characterization of online groups along space, time, and social dimensionsJaccard similarity between declared and detected groups as a function of their sizes. Diagonal shows an interesting pattern (a) which is not reproduced by randomized groups (b). We subtract (b) from (a) and plot the result in (c), and a histogram of similarity values for a sample of groups lying at the diagonal in (d). For groups of various sizes, we plot 91th and 99th percentiles of similarity between declared and detected groups (e).Back to article page
