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 "compressed representation of learning spaces"):
  Abstract: Learning Spaces are certain set systems that are applied in the mathematical modeling of education. We propose a suitable compression (without loss of information) of such set systems to facilitate their logical and statistical analysis. Under certain circumstances compression is the prerequisite to calculate the Learning Space in the first place. There are connections to the dual framework of Formal Concept Analysis and in particular to so called attribute exploration.

Includes members:
  Member "the minimal hitting set generation problem algorithms and computation":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "query oriented text summarization based on hypergraph transversals")
  Member "the joy of implications aka pure horn functions mainly a survey":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "dualization in lattices given by implicational bases")
  Member "compactly generating all satisfying truth assignments of a horn formula":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "allsat compressed with wildcards from cnf s to orthogonal dnf s by imposing the clauses one by one")
