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 "implementing the topological model succinctly"):
  Abstract: We show that the topological model, a semantically rich standard to represent GIS data, can be encoded succinctly while efficiently answering a number of topology-related queries. We build on recent succinct planar graph representations so as to encode a model with m edges within \(4m+o(m)\) bits and answer various queries relating nodes, edges, and faces in \(o(\log \log m)\) time, or any time in \(\omega (\log m)\) for a few complex ones.

Includes members:
  Member "fast and compact planar embeddings":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "indexing graph search trees and applications")
  Member "fast set intersection and two patterns matching":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "fast join project query evaluation using matrix multiplication")
  Member "succinct indexable dictionaries with applications to encoding k ary trees prefix sums and multisets":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "path query data structures in practice")
