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 "how to improve the outcome of performance evaluations in terms of percentiles for citation frequencies of my papers"):
  Abstract: Using empirical data I demonstrate that the result of performance evaluations by percentiles can be drastically influenced by the proper choice of the journal in which a manuscript is published.

Includes members:
  Member "examples for counterintuitive behavior of the new citation rank indicator p100 for bibliometric evaluations":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "methods for the generation of normalized citation impact scores in bibliometrics which method best reflects the judgements of experts")
  Member "empirical evidence for the relevance of fractional scoring in the calculation of percentile rank scores":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "examples for counterintuitive behavior of the new citation rank indicator p100 for bibliometric evaluations")
  Member "the normalization of citation counts based on classification systems":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "how well does i3 perform for impact measurement compared to other bibliometric indicators the convergent validity of several field normalized indicators")
  Member "which percentile based approach should be preferred for calculating normalized citation impact values an empirical comparison of five approaches including a newly developed citation rank approach p100":
    also connected through other hyperedges:

    also connected through other hyperedges:
      - Hyperedge HE-7 (induced by source paper "an evaluation of percentile measures of citation impact and a proposal for making them better")
  Member "accounting for the uncertainty in the evaluation of percentile ranks":
    also connected through other hyperedges:
      - Hyperedge HE-8 (induced by source paper "the substantive and practical significance of citation impact differences between institutions guidelines for the analysis of percentiles using effect sizes and confidence intervals")
