human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "similarity adapted publication vectors a note and a correction on measuring cognitive distance in multiple dimensions"):
  Abstract: In a previous article (Rahman, Guns, Rousseau, and Engels, 2015) we described several approaches to determine the cognitive distance between two units. One of these approaches was based on what we called barycenters in N dimensions. The present note corrects this terminology and introduces the more adequate term similarity-adapted publication vectors. Furthermore, we correct an error in normalization and explain the importance of scale invariance in determining cognitive distance. Overall, we find rather strong correlations between cognitive distances obtained by the 2-dimensional (barycenters) and the N-dimensional (similarity-adapted publication vectors) approaches.
