Table 2.

The social dimensions of relationships surveyed by Deri at al.⁹. The last column reports the fraction of nodes of the full communication graph $\mathcal{G}$ that are included in each dimension-specific graph ${\mathcal{G}}_d$. The fraction of nodes in the last column is not exclusive, because nodes can be found in multiple dimension-specific graphs. Our work focused mainly on the dimensions of knowledge and support.
