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 "the accuracy of the demographic inferences shown on google s ad settings"):
  Abstract: Google's Ad Settings shows the gender and age that Google has inferred about a web user. We compare the inferred values to the self-reported values of 501 survey participants. We find that Google often does not show an inference, but when it does, it is typically correct. We explore which usage characteristics, such as using privacy enhancing technologies, are associated with Google's accuracy, but found no significant results.

Includes members:
  Member "an empirical study of mobile ad targeting":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "exploring server side blocking of regions")
  Member "a methodology for information flow experiments":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "influence in classification via cooperative game theory")
  Member "adscape harvesting and analyzing online display ads":
