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 "mathematical foundations of inconsistency analysis in pairwise comparisons"):
  Abstract: This study, based on contemporary mathematical foun- dations, presents an abelian group approach to analyzing inconsis- tency in pairwise comparisons. A general and precise notion of an inconsistency indicator map on a group, taking values in an abelian linearly ordered group, is introduced. For it, metrics and general- ized metrics are investigated. Every inconsistency indicator map generates an inconsistency index of a pairwise comparisons matrix. The inconsistency analysis in pairwise comparisons has broad ap- plications in multi-criteria decision making.
