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 "predicting results of the research excellence framework using departmental h index revisited"):
  Abstract: We revisit our recent study [Predicting results of the Research Excellence Framework using departmental h-index, Scientometrics, 2014, 102:2165---2180; arXiv:1411.1996] in which we attempted to predict outcomes of the UK's Research Excellence Framework (REF 2014) using the so-called departmental h-index. Here we report that our predictions failed to anticipate with any accuracy either overall REF outcomes or movements of individual institutions in the rankings relative to their positions in the previous Research Assessment Exercise (RAE 2008).
