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 "ensemble clustering for graphs"):
  Abstract: We propose an ensemble clustering algorithm for graphs (ECG), which is based on the Louvain algorithm and the concept of consensus clustering. We validate our approach by replicating a recently published study comparing graph clustering algorithms over artificial networks, showing that ECG outperforms the leading algorithms from that study. We also illustrate how the ensemble obtained with ECG can be used to quantify the presence of community structure in the graph.

  Member "comparing graph clusterings set partition measures vs graph aware measures":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "ensemble clustering for graphs comparisons and applications")
  Member "comparative evaluation of community detection algorithms a topological approach":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "ensemble clustering for graphs comparisons and applications")
