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 "shallow discourse parsing using distributed argument representations and bayesian optimization"):
  Abstract: This paper describes the Georgia Tech team's approach to the CoNLL-2016 supplementary evaluation on discourse relation sense classification. We use long short-term memories (LSTM) to induce distributed representations of each argument, and then combine these representations with surface features in a neural network. The architecture of the neural network is determined by Bayesian hyperparameter search.

Includes members:
  Member "when are tree structures necessary for deep learning of representations":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "description based text classification with reinforcement learning")
  Member "one vector is not enough entity augmented distributional semantics for discourse relations":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "deep enhanced representation for implicit discourse relation recognition")
