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 "simple concurrent labeling algorithms for connected components"):
  Abstract: We present new concurrent labeling algorithms for finding connected components, and we study their theoretical efficiency. Even though many such algorithms have been proposed and many experiments with them have been done, our algorithms are simpler. We obtain an $O(\lg n)$ step bound for one of them using a novel multi-round analysis. We conjecture that our other algorithms also take $O(\lg n)$ steps but our best result in this direction is an $O(\lg^2 n)$ bound for one of them. We also point out some gaps in previous analyses of similar algorithms. Our results show that even a basic problem like connected components still has secrets to reveal.
