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 "reviewers ratings and bibliometric indicators hand in hand when assessing over research proposals"):
  Abstract: Background#R##N#The peer review system has been traditionally challenged due to its many limitations especially for allocating funding. Bibliometric indicators may well present themselves as a complement.

Includes members:
  Member "national peer review research assessment exercises for the hard sciences can be a complete waste of money the italian case":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "peer review versus bibliometrics which method better predicts the scholarly impact of publications")
  Member "towards a book publishers citation reports first approach using the book citation index":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "the insoluble problems of books what does altmetric com have to offer")
  Member "national research assessment exercises a comparison of peer review and bibliometrics rankings":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "peer review versus bibliometrics which method better predicts the scholarly impact of publications")
  Member "allocative efficiency in public research funding can bibliometrics help":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "diversification versus specialization in scientific research which strategy pays off")
