Network dataset meta-information.

Basic information about the relationships that the real network datasets used for our power-hop analysis represent. For every network we define its nodes and edges, as well as its type (i.e., directed vs undirected). For the collaboration networks, HEP-TH captures the collaborations between high energy theoretical physicist, while the GR-QC captures the collaborations between physicist working on general relativity and quantum cosmology. Furthermore, the urban networks capture consecutive visitations by Foursquare users to venues in New York City and San Francisco respectively.
