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 "the construction of characteristic matrixes of dynamic coverings in the covering information systems"):
  Abstract: This paper further investigates the construction of characteristic matrixes of the dynamic covering. First, we introduce an approach to computing the type-1 and type-2 characteristic matrixes of the covering. Then, we discuss that how to get the type-1 and type-2 characteristic matrixes of the dynamic covering. Afterwards, several illustrative examples are employed to show the processes of constructing the type-1 and type-2 characteristic matrixes of the dynamic covering can be simplified greatly by the proposed approach.
