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 "exptime tableaux for the description logic shiq based on global state caching and integer linear feasibility checking"):
  Abstract: We give the first ExpTime (complexity-optimal) tableau decision procedure for checking satisfiability of a knowledge base in the description logic SHIQ when numbers are coded in unary. Our procedure is based on global state caching and integer linear feasibility checking.

Includes members:
  Member "a cut free exptime tableau decision procedure for the logic extending converse pdl with regular inclusion axioms":
    also connected through other hyperedges:
      (none)
  Member "optimal and cut free tableaux for propositional dynamic logic with converse":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "exptime tableaux for type pdl")
  Member "complexity results and practical algorithms for logics in knowledge representation":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "satisfiability and query answering in description logics with global and local cardinality constraints")
  Member "reasoning with individuals for the description logic shiq":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "conjunctive query answering via a fragment of set theory extended version")
