Webb2 juli 2015 · SimRank would be ideal for this purpose, except that it applies to unweighted graphs. It's easy to adapt the matrix representation of SimRank to use weighted edges: S = max { C ⋅ ( A T ⋅ S ⋅ A), I } Just replace the entries in … WebbThus, we see two more positive examples and we see our ﬁrst negative example. 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. Finally, when X = D, there are four neighbors.

Webb10 maj 2024 · 从 SimRank 到 SimRank++上一篇博客《SimRank与视频相似度计算》介绍了 SimRank$^{[1]}$ 及其在视频推荐中的应用，这一篇再谈谈 SimRank++。顾名思义，SimRank++ 是在 SimRank 的基础上做了一些优化，在文献 [2] 中提出时是为了解决搜索词改写的问题，本质上也就是计算搜索词的相似度。 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.

SimRank basic MC framework returns an approximated SimRank score in O ¹n w tº time, where n w is the number of walks sampled from each node and t is a bound on their length. To e ciently approximate SemSim we develop an analogous MC framework, thereby enabling a direct application of SimRank optimizations.

Another typical example is the graph modeling for a social network, where vertices represent individual persons and edges represent their friend relationships.
