The topological properties calculated in the SSN.

Topological features	Description
Betweenness centrality	The fraction of shortest paths between node pairs that pass through the node
Clustering coefficient	The number of triangles (3 loops) that pass through this node
PageRank	The number and PageRank metric of all nodes that link to the node
Degree	The number of edges connected to the node
