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 "faster compressed quadtrees"):
  Abstract: Real-world point sets tend to be clustered, so using a machine word for each point is wasteful. In this paper we first bound the number of nodes in the quadtree for a point set in terms of the points' clustering. We then describe a quadtree data structure that uses $\mathcal{O} (1)$ bits per node and supports faster queries than previous structures with this property. Finally, we present experimental evidence that our structure is practical.

Includes members:
  Member "layered label propagation a multiresolution coordinate free ordering for compressing social networks":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "2ps high quality edge partitioning with two phase streaming")
  Member "succinct representation of well spaced point clouds":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "near optimal euclidean metric compression")
  Member "fully functional static and dynamic succinct trees":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "fully functional bidirectional burrows wheeler indexes")
