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 identify the roots of broad research topics and fields the introduction of rpys sampling using the example of climate change research"):
  Abstract: Since the introduction of the reference publication year spectroscopy (RPYS) method and the corresponding programme CRExplorer, many studies have been published revealing the historical roots of to...

Includes members:
  Member "climate change research in view of bibliometrics":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "does the public discuss other topics on climate change than researchers a comparison of explorative networks based on author keywords and hashtags")
  Member "introducing citedreferencesexplorer crexplorer a program for reference publication year spectroscopy with cited references standardization":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "identifying single influential publications in a research field new analysis opportunities of the crexplorer")
  Member "growth rates of modern science a bibliometric analysis based on the number of publications and cited references":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "citation text generation")
  Member "detecting the historical roots of research fields by reference publication year spectroscopy rpys":
    also connected through other hyperedges:
