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 "scholia and scientometrics with wikidata"):
  Abstract: Scholia is a tool to handle scientific bibliographic information in Wikidata. The Scholia Web service creates on-the-fly scholarly profiles for researchers, organizations, journals, publishers, individual scholarly works, and for research topics. To collect the data, it queries the SPARQL-based Wikidata Query Service. Among several display formats available in Scholia are lists of publications for individual researchers and organizations, publications per year, employment timelines, as well as co-author networks and citation graphs. The Python package implementing the Web service is also able to format Wikidata bibliographic entries for use in LaTeX/BIBTeX.

Includes members:
  Member "altmetrics in the wild using social media to explore scholarly impact":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "readership data and research impact")
  Member "two dimensional ranking of wikipedia articles":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "novel version of pagerank cheirank and 2drank for wikipedia in multilingual network using social impact")
