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. Webb1 maj 2024 · For example, the World Wide Web can be naturally modeled as a graph, with webpages as the vertices and hyperlinks as the edges. Another typical example is the graph modeling for a social network, where vertices represent individual persons and edges represent their friend relationships.

If X = B, there are again three neighbors, but only one pair of neighbors, A and C, has an edge. Thus, we have two more negative examples, and one positive example, for a total of seven positive and three negative.
