Edge Weight Prediction in Weighted Signed Networks

Abstract: Weighted signed networks (WSNs) are networks in which edges are labeled with positive and negative weights. WSNs can capture like/dislike, trust/distrust, and other social relationships between people. In this paper, we consider the problem of predicting the weights of edges in such networks. We propose two novel measures of node behavior: the goodness of a node intuitively captures how much this node is liked/trusted by other nodes, while the fairness of a node captures how fair the node is in rating other no… Show more

“…In the definition of edge weight prediction on WSNs by Kumar et al [KSSF16], they adapted several algorithms for this task, providing us with a set of baseline measures on these datasets. We first use a basic method of Reciprocal [KSSF16], where the edge weight w u,v is same as that of the reciprocal edge weight w v,u if there exists an edge e + v, u ∈ E, and 0 otherwise. We then use two graph algorithms PageRank [PBMW98] and Signed Eigenvector Centrality [Bon07].…”
