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 "data compression of dynamic set valued information systems"):
  Abstract: This paper further investigates the set-valued information system. First, we bring forward three tolerance relations for set-valued information systems and explore their basic properties in detail. Then the data compression is investigated for attribute reductions of set-valued information systems. Afterwards, we discuss the data compression of dynamic set-valued information systems by utilizing the precious compression of the original systems. Several illustrative examples are employed to show that attribute reductions of set-valued information systems can be simplified significantly by our proposed approach.

Includes members:
  Member "some improved results on communication between information systems":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "generalized fuzzy rough sets based on fuzzy coverings")
  Member "covering rough sets based on neighborhoods an approach without using neighborhoods":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "incremental approaches to knowledge reduction of covering decision information systems with variations of coverings")
