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 "a 1 varepsilon embedding of low highway dimension graphs into bounded treewidth graphs"):
  Abstract: Graphs with bounded highway dimension were introduced by Abraham et al. [Proceedings of SODA 2010, pp. 782--793] as a model of transportation networks. We show that any such graph can be embedded i...

Includes members:
  Member "beyond highway dimension small distance labels using tree skeletons":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "travelling on graphs with small highway dimension")
  Member "fixed parameter approximations for k center problems in low highway dimension graphs":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "travelling on graphs with small highway dimension")
  Member "the traveling salesman problem low dimensionality implies a polynomial time approximation scheme":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a quasi polynomial algorithm for well spaced hyperbolic tsp")
  Member "cops robbers and threatening skeletons padded decomposition for minor free graphs":
    also connected through other hyperedges:
