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 necessary and sufficient condition for two relations to induce the same definable set family"):
  Abstract: In Pawlak rough sets, the structure of the definable set families is simple and clear, but in generalizing rough sets, the structure of the definable set families is a bit more complex. There has been much research work focusing on this topic. However, as a fundamental issue in relation based rough sets, under what condition two relations induce the same definable set family has not been discussed. In this paper, based on the concept of the closure of relations, we present a necessary and sufficient condition for two relations to induce the same definable set family.

Includes members:
  Member "matroidal structure of rough sets based on serial and transitive relations":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "rough matroids based on coverings")
  Member "geometric lattice structure of covering based rough sets through matroids":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "geometric lattice structure of covering and its application to attribute reduction through matroids")
