human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "analysis of computer science communities based on dblp"
  Abstract: It is popular nowadays to bring techniques from bibliometrics and scientometrics into the world of digital libraries to explore mechanisms which underlie community development. In this paper we use the DBLP data to investigate the author's scientific career, and analyze some of the computer science communities. We compare them in terms of productivity and population stability, and use these features to compare the sets of top-ranked conferences with their lower ranked counterparts.

Connected through hyperedge HE-1 (induced by source paper "analyzing the evolution and diversity of sbes program committee"):

    - "csindexbr exploring the brazilian scientific production in computer science"

Connected through hyperedge HE-2 (induced by source paper "discovering archetypes to interpret evolution of individual behavior"):
