Table 1 Properties of the different layers of the scientific networks and the Core over which link prediction is computed. We show the number of nodes N, the total weight \(W = \sum_{i j \alpha } w_{ij}^{\alpha }\), the average degree \(\langle k\rangle \), the overlap between the collaboration layer and the other layers, and the global clustering coefficient C. The overlap is defined as the fraction of links in the collaboration layer that are also present in citations layer or keyword layers
