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 "the dispersion of the citation distribution of top scientists publications"):
  Abstract: This work explores the distribution of citations for the publications of top scientists. A first objective is to find out whether the 80---20 Pareto rule applies, that is if 80 % of the citations to a top scientist's work concern 20 % of their publications. Observing that the rule does not apply, we also measure the dispersion of the citation distribution by means of the Gini coefficient. Further, we investigate the question of what share of a top scientist' publications go uncited. Finally, we study the relation between the dispersion of the citation distribution and the share of uncited publications. As well as the overall level, the analyses are carried out at the field and discipline level, to assess differences across them.
