human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "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.

Connected through hyperedge HE-1 (induced by source paper "peer review versus bibliometrics which method better predicts the scholarly impact of publications"):
  with members:
    - "systematic analysis of agreement between metrics and peer review in the uk ref"
    - "predicting publication long term impact through a combination of early citations and journal impact factor"
    - "peer review and citation data in predicting university rankings a large scale analysis"
    - "do citations and readership identify seminal publications"
    - "revisiting the scientometric conceptualization of impact and its measurement"
    - "selecting competent referees to assess research projects proposals a study of referees registers"
    - "do they agree bibliometric evaluation versus informed peer review in the italian research assessment exercise"
    - "refrain from adopting the combination of citation and journal metrics to grade publications as used in the italian national research assessment exercise vqr 2011 2014"

Connected through hyperedge HE-2 (induced by source paper "analyzing the disciplinary focus of universities can rankings be a one size fits all"):
  with members:
    - "what do university rankings by fields rank exploring discrepancies between the organizational structure of universities and bibliometric classifications"
    - "does google scholar contain all highly cited documents 1950 2013"
    - "an insight into the importance of national university rankings in an international context the case of the i ugr rankings of spanish universities"
    - "citation analysis may severely underestimate the impact of clinical research as compared to basic research"
