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 "refinement in the tableau synthesis framework"):
  Abstract: This paper is concerned with the possibilities of refining and improving calculi generated in the tableau synthesis framework. A general method in the tableau synthesis framework allows to reduce the branching factor of tableau rules and preserves completeness if a general rule refinement condition holds. In this paper we consider two approaches to satisfy this general rule refinement condition.

Includes members:
  Member "using tableau to decide description logics with full role negation and identity":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "blocking and other enhancements for bottom up model generation methods")
  Member "automated synthesis of tableau calculi":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "blocking and other enhancements for bottom up model generation methods")
  Member "hypertableau reasoning for description logics":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "knowledge graphs")
