human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "computing with logic as operator elimination the toyelim system"
  Abstract: A prototype system is described whose core functionality is, based on propositional logic, the elimination of second-order operators, such as Boolean quantifiers and operators for projection, forgetting and circumscription. This approach allows to express many representational and computational tasks in knowledge representation - for example computation of abductive explanations and models with respect to logic programming semantics - in a uniform operational system, backed by a uniform classical semantic framework.

Connected through hyperedge HE-1 (induced by source paper "facets of the pie environment for proving interpolating and eliminating on the basis of first order logic"):
  with members:
    - "craig interpolation and access interpolation with clausal first order tableaux"

Connected through hyperedge HE-2 (induced by source paper "pie proving interpolating and eliminating on the basis of first order logic"):
  with members:
    - "craig interpolation and access interpolation with clausal first order tableaux"
    - "foundations for uniform interpolation and forgetting in expressive description logics"
