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 "on axiomatization of inconsistency indicators for pairwise comparisons"):
  Abstract: This study examines the notion of inconsistency in pairwise comparisons for providing an axiomatization for it. It also proposes two inconsistency indicators for pairwise comparisons. The primary motivation for the inconsistency reduction is expressed by a computer industry concept “garbage in, garbage out”. The quality of the output depends on the quality of the input.

Includes members:
  Member "studying a set of properties of inconsistency indices for pairwise comparisons":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "satisfaction of the condition of order preservation a simulation study")
  Member "a monte carlo study of pairwise comparisons":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the convergence of the pairwise comparisons inconsistency reduction process")
  Member "axiomatic properties of inconsistency indices for pairwise comparisons":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "inconsistency indices for incomplete pairwise comparisons matrices")
  Member "on distance based inconsistency reduction algorithms for pairwise comparisons":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "on orthogonal projections on the space of consistent pairwise comparisons matrices")
