human: Given a node-centered hypergraph: <hypergraph>, where nodes represent authors and hyperedges represent groups of authors who co-authored the same paper.

Details of the hypergraph:
Center node: "Preference modeling on totally ordered sets by the Sugeno integral"
  Abstract: We present in this paper necessary and sufficient conditions for the representation of preferences in a decision-making problem, by the Sugeno integral, in a purely ordinal framework. We distinguish between strong representation (exact) and weak representation (no contradiction on strict preferences).

Connected through hyperedge HE-1 (induced by source paper "Representation of preferences over a finite scale by a mean operator"):
