human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups papers that share a common citing paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "A Survey of Theory and Methods of Invariant Item Ordering"):
  Abstract: This work was initiated while Junker was visiting the University of Utrecht with the support of a Carnegie Mellon University Faculty Development Grant, and the generous hospitality of the Social Sciences Faculty, University of Utrecht. Additional support was provided by the Office of Naval Research, Cognitive Sciences Division, Grant N00014-87-K-0277 and the National Institute of Mental Health, Training Grant MH15758.
