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 "centrality in dynamic competition networks"):
  Abstract: Competition networks are formed via adversarial interactions between actors. The Dynamic Competition Hypothesis predicts that influential actors in competition networks should have a large number of common out-neighbors with many other nodes. We empirically study this idea as a centrality score and find the measure predictive of importance in several real-world networks including food webs, conflict networks, and voting data from Survivor.

Includes members:
  Member "dynamic competition networks detecting alliances and leaders":
    also connected through other hyperedges:
      (none)
  Member "the spatial ecology of war and peace":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "dynamic competition networks detecting alliances and leaders")
  Member "negative link prediction in social media":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "social science guided feature engineering a novel approach to signed link analysis")
