Many applications require a measure of "similarity" between objects. One obvious example is the "find-similar-document" query, on traditional text corpora or the World-Wide Web. More generally, a similarity measure can be used to cluster objects, such as for collaborative filtering in a recommender system, in which “similar” users and items are grouped based on the users’ preferences.

WebbSimRank is a classic measure of the similarities of nodes in a graph. Given a nodeuin graphG=(V,E), a single-source SimRank query returns the SimRank similarities s(u,v)be … Webb22 nov. 2015 · Basic SimRank Equation Let's denote the similarity between objects a and b by s (a,b) ∈ [0, 1]. Following our earlier motivation, we write a recursive equation for s (a,b). If a = b then s (a, b) is defined to be 1. Otherwise, where C is a constant between 0 and 1. A slight technicality here is that either a or b may not have any in-neighbors.
