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 "unfolding the structure of a document using deep learning"):
  Abstract: This work was partially supported by National Science Foundation grant 1549697 and gifts from IBM and Northrop Grumman.

Includes members:
  Member "understanding and representing the semantics of large structured documents":
    also connected through other hyperedges:
      (none)
  Member "understanding the logical and semantic structure of large documents":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "table of contents generation on contemporary documents")
  Member "contextual lstm clstm models for large scale nlp tasks":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "connecting gans and mfgs")
  Member "tensorflow large scale machine learning on heterogeneous distributed systems":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "chameleon a deep learning meta architecture for news recommender systems phd thesis")
  Member "text understanding from scratch":
    also connected through other hyperedges:
