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 "binarized pmi matrix bridging word embeddings and hyperbolic spaces"):
  Abstract: We show analytically that removing sigmoid transformation in the SGNS objective does not harm the quality of word vectors significantly and at the same time is related to factorizing a binarized PMI matrix which, in turn, can be treated as an adjacency matrix of a certain graph. Empirically, such graph is a complex network, i.e. it has strong clustering and scale-free degree distribution, and is tightly connected with hyperbolic spaces. In short, we show the connection between static word embeddings and hyperbolic spaces through the binarized PMI matrix using analytical and empirical methods.
