Considering the network of collaboration among scientists, what are the nodes and links?

  1. Nodes are the scientists and links connect scientists with at least one paper in common.
  2. Nodes are papers and scientists, and links connect a scientist to a paper he/she authored.
  3. Nodes are the topics and the links connect a scientist to a topic of his/her interest.
  4. Nodes are scientists, and two scientists are connected if they work in the same department.
  5. None of the above.
