偏好依恋模型中共同朋友的成长

Growth of Common Friends in a Preferential Attachment Model

Bikramjit Das, Souvik Ghosh

摘要:

图中的共同朋友(或连接)的数量是两个节点之间的接近度的常用度量。这种测量被用于大型在线社交网络中的链接预测算法和推荐系统。在线性偏好依恋模型中,我们得到了共同朋友数量的增长率。我们应用我们的结果来估计共同朋友的数量。我们还观察到一个相变的限制行为的共同朋友的数量;根据模型的参数的范围,增长要么是幂律,或,对数,或静态的图形的大小。

英文摘要:

The number of common friends (or connections) in a graph is a commonly used measure of proximity between two nodes. Such measures are used in link prediction algorithms and recommendation systems in large online social networks. We obtain the rate of growth of the number of common friends in a linear preferential attachment model. We apply our result to develop an estimate for the number of common friends. We also observe a phase transition in the limiting behavior of the number of common friends; depending on the range of the parameters of the model, the growth is either power-law, or, logarithmic, or static with the size of the graph.
